Description

Invention Field

[0001] This invention belongs to the field of compositions comprising plant fibers, hyperbranched polylysine, and components having groups having the following formula. The composition is particularly suitable for preparing objects such as engineered wood, for example, fiberboard.

[0002] background In the context of this invention and in the literature, polylysine refers to various types of lysine homopolymers that may differ from each other in stereochemistry and linkage position. Lysine, as a precursor amino acid (in either of its two enantiomers, namely D- and L-lysine; “L” and “D” refer to the chirality at the central carbon atom of lysine), contains two amino groups; one at the α-carbon and one at the α-carbon. Either of these two amino groups can be the polymerization position, thereby producing α-polylysine or α-polylysine.

[0003] Fibers (or fibers; these terms are used interchangeably in the context of this invention) constitute a class of materials that are continuous filaments or discrete, elongated sheets, similar in length to thread. Human uses of fibers are diverse. They can be spun into filaments, strings, or ropes, used as reinforcing agents in composite materials made into sheets to manufacture products such as paper or felt. Fibers are commonly used in the manufacture of other materials. Fibers can be recycled. In the context of this invention, the term "fiber" also includes recycled fibers.

[0004] Based on their origin, fibers are divided into two main categories: natural fibers and synthetic fibers. Synthetic fibers are also called man-made, artificial, or manufactured fibers.

[0005] Natural fibers are further divided into: i) mineral fibers (e.g., asbestos, wollastonite, attapulgite, hydrous kaolinite), ii) animal fibers (e.g., silk, wool, sinew, cashmere, mohair, angora rabbit hair, animal hair), and iii) plant fibers based on the arrangement of cellulose (also known as "natural cellulose fibers") or the arrangement of cellulose with lignin (also known as "natural lignocellulose fibers"), and derived from sources of natural cellulose or natural cellulose with lignin, such as plants, which are living organisms that absorb water and inorganic substances through their roots and synthesize nutrients in their leaves through photosynthesis using the green pigment chlorophyll, exemplified by trees, bamboo, shrubs, herbs, grasses, ferns, and mosses. Examples of plant fibers include, but are not limited to, wood fiber, reed fiber, bamboo fiber, seaweed, jute fiber, flax fiber, hemp seed fiber, ramie fiber, Manila fiber, sisal fiber, kapok fiber, cotton, banana fiber, coconut fiber, rye fiber, wheat fiber, rice fiber, kenaf (hibiscus cannabinus) fiber, straw fiber, grass fiber, leaf fiber, and mixtures thereof.

[0006] Synthetic fibers (also known as man-made or artificial fibers) can be further classified into: i) cellulose fibers regenerated from natural resources, also known as regenerated cellulose fibers (e.g., rayon, modal, lyocell, cellulose acetate, cellulose triacetate), ii) inorganic fibers and iii) polymer fibers.

[0007] Cellulose fibers are a subset of fibers. Cellulose fibers are fibers derived from cellulose of any source, whether natural or manufactured (the latter also known as synthetic cellulose fibers). Therefore, cellulose fibers can be natural (e.g., from natural cellulose sources such as cellulose fibers from trees (including bamboo) and seaweed) or synthetic (e.g., cellulose fibers regenerated from natural cellulose, such as rayon, modal, lyocell, cellulose acetate, and cellulose triacetate). Synthetic cellulose fibers are also referred to in the art as man-made cellulose fibers, regenerated cellulose fibers, or manufactured cellulose fibers or artificial cellulose fibers.

[0008] In the context of this invention, the terms “synthetic cellulose fiber,” “man-made cellulose fiber,” “made cellulose fiber,” “artificial cellulose fiber,” or “regenerated cellulose fiber” are used interchangeably, and these terms are used to distinguish synthetic cellulose fiber from natural cellulose fiber and natural lignocellulose fiber, both of which are plant fibers.

[0009] One of the most important fiber types is wood fiber, including recycled wood fiber. There are two main types of wood: a) softwood and b) hardwood. Softwood comes from coniferous trees. Exemplary softwoods include, but are not limited to, pine, mahogany, and fir. Softwood can be used for furniture and doors, but is primarily used for the construction of roof trusses and vertical partition walls. Hardwood comes from leafy trees. These trees may have flowers and produce seeds, such as nuts and fruits. Exemplary hardwoods include, but are not limited to, oak, beech, and mahogany. Hardwood is denser and also stronger and more durable than softwood. They are used for furniture and are generally more expensive than softwood. Wood can be recycled. In the context of this invention, the term "wood" also includes recycled wood.

[0010] During timber preparation, timber (softwood, hardwood) is used to manufacture timber (also known as lumber); timber is actually the wood used to make beams and slats. In the context of this invention, the term "solid wood" is used to distinguish timber from engineered wood.

[0011] Engineered timber (also known as mass timber, composite timber, artificial timber, or engineered wood) includes a range of derivative timber products made by bonding or fixing together various wood elements (such as fibers, filaments, yarns, strips, bundles, threads, short fiber yarns, particles, fragments (such as wood chips, sawdust), shavings (such as sawmill shavings), veneers, sheets, boards, pulp (such as wood pulp), and mixtures thereof) through various fixing methods to effectively form composite materials. Exemplary types of engineered timber include, but are not limited to, plywood, densified timber (including chemically densified timber), fiberboard [this term includes low-density fiberboard (LDF; also known as particle board or chip board), medium-density fiberboard (MDF), and high-density fiberboard (HDF; also known as waffle board or flakeboard)], oriented strand board (OSB), laminated timber (glulam; glued laminated timber), laminated veneer lumber (LVL), cross-laminated timber (CLT), parallel strand lumber (PSL), laminated strand lumber (LSL), finger joints, beams (including I-joints and I-beams), trusses (including roof and floor trusses), and transparent wood composites. Engineered timber products are engineered to precise design specifications, tested to meet national or international standards, and provide consistency and predictability in their structural performance. Engineered timber products are used in a wide range of applications, from residential to commercial buildings and industrial products.

[0012] Fiberboard constitutes a subset of engineered wood. Types of fiberboard (in ascending order of density) include low-density fiberboard (LDF; also known as particleboard or chipboard), medium-density fiberboard (MDF), and high-density fiberboard (HDF; also known as waffle board or chipboard). In the context of this invention, a density of up to 500 kg / m³ is used. 3 (Preferred to be at least 100 and at most 500 kg / m) 3 Fiberboard with a density higher than 500 kg / m³ is considered LDF. In the context of this invention, LDF refers to fiberboard with a density higher than 500 kg / m³. 3 And at most 1000 kg / m 3 (Preferred weight: at least 550 and at most 800 kg / m³) 3 Fiberboard with a density higher than 1000 kg / m³ is considered MDF. In the context of this invention, MDF refers to fiberboard with a density greater than 1000 kg / m³. 3(Preferred value is above 1000 and at most 1500 kg / m) 3 More preferably, higher than 1000 and at most 1100 kg / m 3 Fiberboard made from materials such as MDF is considered HDF. In principle, fiberboard can be formed using either wet or dry forming processes. In a wet forming process, water is used to distribute the fibers into a pad, which is then pressed into a board. In a dry process, fibers from a refiner pass through a dryer and spray line, where an adhesive is applied, and the fiber is then formed into a web, which is pressed into a board. Typical fiberboard manufacturing (on an industrial scale) begins with wood cutting: fresh or recycled wood material is cut and sorted into small pieces of similar size. The chips are washed to remove things like dust and sand. Metal scraps such as nails can be removed using magnets placed above a conveyor belt used to move the chips forward. In the case of MDF, for example, the chips are then steam-treated to soften them so that the fibers can separate. A small amount of paraffin wax is added to the steam-treated chips, and they are transformed into fluffy fibers in a fiber separator, and shortly thereafter sprayed with urea-formaldehyde (UF) or phenolic (PF) resin. The wax prevents the fibers from clumping together during storage. In the case of particleboard, the fibers or debris can also be sprayed with additional resin before the next step. The fibers or debris are arranged into a uniform "pad" on a conveyor belt. This pad is pre-compressed and then hot-pressed (applying heat and pressure simultaneously). The hot pressing bonds the fibers or debris together. The board is then cooled, trimmed, sanded, and can be faceted or laminated. UF resin is primarily used in the MDF industry.

[0013] In recent years, there has been an increasing need for compositions capable of rapid curing at low temperatures to prepare fiberboard [this term includes low-density fiberboard (LDF; also known as particleboard or chipboard), medium-density fiberboard (MDF), and high-density fiberboard (HDF; also known as waffle board or chipboard)], said fiberboard having: - Internal bond strength of at least 0.3 MPa, - A fracture modulus of at least 9 MPa (R b ),and - Apparent elastic modulus (E) of at least 1600 MPa.

[0014] Fracture modulus (R) b Both apparent elastic modulus (R) and apparent elastic modulus (E) constitute the bending properties of an object, such as fiberboard. The internal bond strength and bending properties of fiberboard are crucial to their consumer acceptance and their commercial success. For internal bond strength, R... bFiberboards that do not meet at least one of the aforementioned thresholds, as defined in E, fail to exhibit a level acceptable to the end consumer. Therefore, fiberboards with enhanced internal bond strength and flexural properties are desirable. Enhanced flexural properties allow for greater resistance to mechanical and / or physical stresses experienced by the fiberboard during its service life, including but not limited to its preparation, packaging, unpacking, transport, storage, and use. Fiberboards suffering from poor flexural properties are typically brittle and exhibit little or no resistance to mechanical and / or physical stresses. Consequently, poor flexural properties severely limit their applications and uses (if any) and / or their lifespan (once used), and are therefore generally rejected by consumers. Furthermore, enhanced internal bond strength is also desirable because it ensures acceptable physical integrity and allows for greater resistance to mechanical and / or physical stresses experienced by the fiberboard during its service life. Rapid curing at low temperatures is also highly desirable for compositions suitable for preparing fiberboards, as it improves preparation efficiency, increases throughput, and reduces the amount of energy required to cure the composition.

The particle size distribution of wood chips is determined by vibrating sieve method using a sieve with apertures of 3.15 mm or larger, according to ISO 17827-1:2016. According to this standard (ISO 17827-1:2016), the median (d50) of the particle size distribution is reported and defined as the calculated particle size of the sample in which 50% of the particles have a mass lower than or higher than d50%. The median is graphically established by the intersection of the cumulative distribution curve and the 50% line [(X-axis: particle / aperture size (mm), and Y-axis: cumulative weight % (%)].

[0063] In this article, "room temperature" refers to 23 ± 0.5℃.

[0082] The topic of this section is referred to as "A1" in the instruction manual.

[0083] To illustrate, Figure 1 Hyperbranched polylysine with a theoretical (calculated) molecular weight of 0.4 dB and 3350.6 Da was described, while Figure 2 The primary ammonium salts of hyperbranched polylysine were described, in which some primary ammonium cations (-NH3) exist in the structure of the primary ammonium salts that counteract hyperbranched polylysine. +The anion of ) is chloride ion, and among them Figure 2 The primary ammonium salt of hyperbranched polylysine has a theoretical (calculated) molecular weight of 0.4 dB and 3569.3 Da.

[0084] Lysine, as a precursor amino acid (either of its two enantiomers, namely D- and L-lysine; "L" and "D" refer to the chirality at the central carbon atom of lysine), contains two amino groups; one at the α-carbon and one at the α-carbon. Either of these two amino groups can be the polymerization position. In principle, polylysine is formed from lysine or a lysine salt (L-lysine, D-lysine, or any mixture of L-lysine, such as a racemic mixture; or L-lysine salt, D-lysine salt, or any mixture thereof, such as a racemic mixture) in a condensation polymerization reaction, wherein water is released when the amino group of one lysine molecule and the carboxyl group of another lysine molecule react with each other to form an amide bond in the presence of water. Removal of water from the reaction mixture favors the formation of polylysine.

[0085] Hyperbranched polylysine can be prepared by various methods. In principle, methods for preparing hyperbranched polylysine can be classified into four main categories: i) methods based on the ring-opening addition polymerization of e-protected L-lysine-N-carboxylic anhydride (NCA) with a nucleophilic primer; ii) methods using a derivative of L-lysine*xHCl activated at the carboxyl group; iii) methods involving the direct thermal addition polymerization of L-lysine; and iv) methods involving a salt of lysine with at least one acid in the presence of at least one catalyst selected from tertiary amines, basic alkali metal salts, alkaline earth metal salts, quaternary ammonium salts, alkoxides, alkanoates, chelates, and organometallic compounds of metals from groups IIIA to VIIIA or IB to VB of the periodic table. The following paragraphs in this section provide some examples of methods for preparing hyperbranched polylysine, such as those for the claimed invention.

[0086] Hyperbranched polylysine can be prepared via the so-called AB2 pathway. AB2 is a term used to represent a trifunctional monomer containing one reactive group A and two reactive groups B; hyperbranched polymers can be prepared via intermolecular reactions when these groups A and B are reactive with each other. Lysine is an example of such a trifunctional monomer, wherein the reactive group A is a carboxyl group, and each of the two reactive groups B is an amino group of lysine, and wherein these A and B groups in lysine are reactive with each other; therefore, the AB2 polymerization pathway of lysine yields hyperbranched polylysine.

[0087] Hyperbranched polylysine can also be prepared as follows: 50% by weight of L-lysine in water is charged into a reactor, such as a glass reactor equipped with a distillation apparatus. After the L-lysine in water (50% by weight) has been charged into the reactor, the reactor is slowly heated (over 2-8 hours) to 120-190°C (this slow temperature increase is necessary to avoid precipitation of unreacted L-lysine in the reactor, which may occur if too much water is distilled off before full reaction). When the desired reaction temperature is reached, the reaction is then continued at the desired temperature for 2-30 hours. Optionally, 50% by weight of L-lysine in water can be added to the reactor during distillation to maintain a constant packing level. The reaction is monitored by taking samples at regular time intervals, diluting the samples in water to 60% by weight, and measuring the apparent viscosity. When the apparent viscosity of these samples is at the desired viscosity, the reaction mixture is discharged. If necessary, water can be added to the reaction mixture before discharge to produce a product with the desired solids content and apparent viscosity. A high-pressure reactor can be used for this method. If a high-pressure reactor is used in this method, L-lysine (50 wt%) in water is charged into the high-pressure reactor, which is equipped with a distillation apparatus connected to the reactor via a pressure relief valve. After the L-lysine (50 wt%) in water is charged into the high-pressure reactor, the pressure in the reactor begins to increase, while the pressure relief valve is closed and the reactor is heated to 120-190°C. During the reaction, the pressure in the reactor is preferably maintained between 1-6 bar (1 bar = 100,000 Pa); this preferred pressure range is also maintained during the reaction by carefully and periodically opening and closing the pressure relief valve to allow distillation of water and a certain amount of pressure release. When the desired reaction temperature is reached, the reaction is then continued at the desired temperature for 2-30 hours. Optionally, L-lysine (50 wt%) in water can be added to the reactor during distillation to maintain a certain packing level. The reaction is monitored by taking samples at regular time intervals, diluting the samples in water to 60 wt%, and measuring the apparent viscosity. When the apparent viscosity of these samples is at the desired viscosity, the reaction mixture is discharged. If desired, water can be added to the reaction mixture before discharge to produce a product with the desired solids content and apparent viscosity. The preparation of hyperbranched polylysine conforming to the invention shown in the examples provides an embodiment of the method described above in this section.

[0088] Another method for preparing hyperbranched polylysine is to use L-lysine hydrochloride as the starting material. The polymerization of L-lysine hydrochloride is carried out as follows: L-lysine hydrochloride (550 g, 3 mol) and NaOH (120 g, 3 mol) are added to a 1-L glass reactor equipped with a distillation apparatus. The reactor is heated to 120-190 °C and stirred for 2 to 30 hours. To monitor the reaction, samples are taken every few hours, dissolved in water to a solid content of 60 wt%, and the apparent viscosity is measured. For discharge, water (calculated to ensure the reaction mixture has a resulting solid content of 70-80 wt%) is added dropwise to the reactor, and the temperature is lowered to 90 °C during water addition. The resulting reaction mixture (70-80 wt% solid content) is then discharged in water at 90 °C.

[0089] Another method for preparing hyperbranched polylysine uses L-lysine hydrochloride and L-lysine as starting materials. Accordingly, L-lysine (50 wt%) (409.4 g, 1.4 mol), L-lysine hydrochloride (255.7 g, 1.4 mol), and NaOH (55.8 g, 1.4 mol) in water are added to a 1-L glass reactor. The reactor is heated to 120–190 °C and stirred for 2–30 hours. To monitor the reaction, samples are taken every few hours, the solid content in water is reduced to 60 wt%, and the apparent viscosity is measured. For discharge, water (calculated to ensure the reaction mixture will have a resulting solid content of 70–80 wt%) is added dropwise to the reactor, and the temperature is lowered to 90 °C during water addition. The resulting reaction mixture (70–80 wt% solid content) is then discharged in water at 90 °C.

[0090] Another method for preparing hyperbranched polylysine is based on the ring-opening addition polymerization of α-protected L-lysine-N-carboxylic anhydride (NCA) with a nucleophilic primer. Examples of this method are disclosed by Klok et al. in WO 2003 / 064452 and Macromolecules 2002, 35, 8718-8723, and by Rodriguez-Hernandez et al. in Biomacromolecules 2003, 4, 249-258. According to the latter, N... e A mixture of trifluoroacetyl-L-lysine-NCA (TFA-Lys-NCA) and Z-lysine-NCA undergoes ring-opening polymerization with an aliphatic amine. In a separate coupling step, N is introduced as a branch point. α N ɛ -Di(9-fluorenyl-methoxycarbonyl)-L-lysine (N α N ɛ-Di(benzyloxycarbonyl)-L-lysine p-nitrophenyl ester was introduced as a branch point, and after deprotection with piperidine, two new amine groups were obtained, which allowed for the ring-opening polymerization of TFA-Lys-NCA and Z-Lys-NCA. These reaction cycles were repeated multiple times. Birchall et al. have also described structurally similar hyperbranched block copolymers in Chem. Commun. 1998, 1335-1336. α-amino acid NCA was subjected to ring-opening polymerization with an aliphatic amine. N,N'-di(benzyloxycarbonyl)-L-lysine p-nitrophenyl ester was introduced as a branch point, and after H2 / Pd / C deprotection, it had two free amine groups for further ring-opening of amino acid NCA. These reaction cycles were repeated multiple times.

[0091] Another method for preparing hyperbranched polylysine is based on a derivative of L-lysine*2HCl activated at the carboxyl group. According to this method, hyperbranched polylysine is prepared in a one-pot synthesis by activating the carboxyl group with N-hydroxysuccinimide (NHS). The NHS-activated L-lysine*2HCl is stirred in dimethyl sulfoxide (DMSO) for 23 hours with a catalytic amount of dimethylaminopyridine (DMAP) and 3 equivalents of diisopropylethylamine (DIEA), and the polymer is precipitated from ethyl acetate.

[0092] Another method for preparing hyperbranched polylysine is based on the thermal addition copolymerization of amino acid mixtures. The thermal addition polymerization of free lysine is known and has been carried out under various reaction conditions. Plaquet et al. (Biochimie 1975, 57 1395-1396) polymerized L-lysine in aqueous solution at 105 °C for up to 10 weeks, or by heating at 165 °C for 8 hours. This reaction was carried out without a catalyst and the yields were very low, invariably below 72.5%. Harada (Bull. Chem. Soc. Japan 1959, 32, 1007-1008) polymerized L-lysine under a nitrogen atmosphere at 180 to 230 °C for 30 minutes to 2 hours. Rohlfing and colleagues (Archives of Biochemistry and Biophysics 1969, 130, 441-448) polymerized L-lysine (free base) under a nitrogen atmosphere between 186°C and 192°C. WO 00 / 71600 describes the condensation of L-lysine monohydrate in a pressure apparatus. Fox et al. (BioSystems 1976, 8, 40-44) used not only L-lysine but also L-lysine*HCl as a starting monomer for thermal polymerization at 195°C. L-lysine*HCl was reacted at 195°C with the addition of orthophosphoric acid.

[0093] US 8846842 B2 discloses yet another method for preparing polylysine that does not require protecting group manipulation or carboxyl group activation, and in which higher molecular weights can be achieved than those known in the prior art. This objective has been achieved by means of a method for preparing non-crosslinked hyperbranched polylysine, which involves the following reaction: (A) A salt of lysine and at least one acid. (B) If appropriate, at least one amino acid other than lysine. (C) If appropriate, at least one dicarboxylic acid or polycarboxylic acid or its copolymerizable derivative, and (D) If appropriate, at least one diamine or polyamine or its copolymerizable derivative. (E) If appropriate, in at least one solvent, at a temperature of 120 to 200 °C, in the presence of at least one catalyst (F), said catalyst (F) being selected from (F1) tertiary amines and amidines, (F2) basic alkali metal salts, alkaline earth metal salts, or quaternary ammonium salts, and (F3) alkoxides, alkanoates, chelates, or organometallic compounds of metals of groups IIIA to VIIIA or IB to VB of the periodic table. This method can be used to prepare materials with a weight-average molecular weight M of up to 750,000 Da. w Non-crosslinked hyperbranched polylysine.

[0094] Hyperbranched polylysine can be synthesized, for example, by direct thermal addition polymerization of L-lysine or its ammonium salt. The thermal addition polymerization of lysine is carried out in the absence of a solvent. WO 2007 / 060119 describes the polycondensation of L-lysine hydrochloride in the presence of sodium hydroxide, water (10 wt%, based on L-lysine hydrochloride), and the catalyst dibutyltin dilaurate. The mixture was heated to an internal temperature of 150 °C with stirring. After a reaction time of 5 hours, water was distilled off under reduced pressure (200 mbar), and after removing the majority of the water, the temperature was slowly increased to 180 °C and the pressure reduced to 10 mbar. After 8 hours, 240 g of the aqueous distillate was collected. Hennon et al. (Biochimie 1971, 53, 215-223) described the preparation of a brown resin starting from an aqueous solution of lysine (50 wt%). The solution was concentrated by evaporation at 105°C to 110°C, then maintained at 165°C to 170°C while being stirred by guiding a weak stream of preheated nitrogen through it. A brown resin was obtained after 8 hours at 165°C to 170°C. Ho et al. described the synthesis of polylysine by thermally heating an aqueous lysine solution at 160°C for 2 days. The obtained polylysine had a branching degree between 0.50 and 0.54. When microwave-assisted heating was used at 200°C, the obtained polylysine had a branching degree between 0.30 and 0.32. US 2013 / 0123148 ​​discloses the preparation of polylysine by heating an aqueous lysine solution in the presence of a catalytic amount of dibutyltin dilaurate. According to the examples in US 2013 / 0123148, the obtained polylysine had a branching degree greater than 0.30.

[0095] WO 2016 / 062578 A1 discloses a method for preparing hyperbranched polylysine suitable for large-scale production of polylysine in improved yields. According to WO 2016 / 062578 A1, polylysine can be prepared by a method comprising the following steps: (a) heating a boiling aqueous reaction mixture containing lysine and water in a weight ratio of 1:10 to 3:1 to a temperature in the range of 135 to 165°C over 2 to 8 hours, for example, 4 to 8 hours; and (b) maintaining the reaction mixture from step (a) at a temperature in the range of 135 to 165°C and at a pressure below atmospheric pressure, wherein water is removed from the mixture, and any temperature rise is less than or equal to 30°C within 60 minutes. Conventional technical-grade aqueous solutions of lysine can be used in the method disclosed in WO 2016 / 062578 A1, and a catalyst is not required. At the end of the second step, the mixture is in a liquid state, such as a melt of polylysine, rather than a resin. Preferably, the aqueous starting mixture is an aqueous solution of lysine in water. The lysine contained in this aqueous starting mixture can be L-lysine, D-lysine, or any mixture of L-lysine and D-lysine, such as a racemic mixture. This aqueous starting mixture can be, for example, an aqueous solution of L-lysine in water containing 50% by weight of L-lysine and 50% by weight of water; for example, ADM liquid L-lysine supplied by Archer Daniels Midland, product code: 035101, or Sewon L-Lysine supplied by Paik Kwang. ®50% liquid feed, or BestAmino™ L-Lysine liquid feed grade supplied by CJ CheilJedang. Polylysine is formed from lysine in a polycondensation reaction, where water is released when the amino group of one lysine molecule and the carboxyl group of another lysine molecule react with each other to form an amide bond in the presence of water. Removal of water from the reaction mixture is beneficial for polylysine formation. Typically, the temperature of the reaction mixture is continuously increased. The method disclosed in WO 2016 / 062578 A1 requires the removal of water from the reaction mixture. Any means suitable for removing water can be used to remove water from the reaction mixture. It is preferred to evaporate water from the mixture. It is most preferred to remove water from the mixture by distillation. This method requires a pressure below atmospheric pressure in the second step. The pressure reduction promotes the evaporation of water and thus accelerates the polycondensation reaction. According to WO 2016 / 062578 A1, the weight-average molecular weight and number-average molecular weight of polylysine depend on the total duration of the method and the temperature of the reaction mixture. Crosslinking is more likely to occur if the reaction mixture is kept at a higher temperature for a longer period of time. Preferably, the method is carried out without a catalyst. This method can be carried out continuously or preferably in batches. It is preferably carried out in a so-called one-pot mode, where lysine is entirely contained in the initial charge and the polycondensation reaction takes place in a reactor with backmixing. However, reaction schemes in multi-stage reactor systems, stirred tank cascades, or tubular reactors are also suitable.

[0096] The primary ammonium salt of hyperbranched polylysine can be prepared, for example, by protonating the amino group of hyperbranched polylysine with an acidic agent, such as a protic acid, alkenyl carboxylic acid, or alkyl sulfonic acid. In the context of this specification, reagents used to prepare the primary ammonium salt of polylysine are referred to as "protonating reagents." Such protonation results in a structure containing at least one primary ammonium cation (-NH3). + The primary ammonium salt of hyperbranched polylysine, wherein the cation is counterbalanced by an anion, and wherein the primary ammonium cation is a cationized form of the amino group of the hyperbranched polylysine. The structure of the anion depends on the reactant used for protonation of the amino group of the hyperbranched polylysine; exemplary anions include, but are not limited to, halide anions (e.g., fluoride, chloride, bromide, iodide), carboxylate anions, and sulfonate anions. Preferably, the anion is selected from halide anions, carboxylate anions, and sulfonate anions; more preferably, the anion is selected from halide anions and carboxylate anions; even more preferably, the anion is selected from halide anions, such as fluoride ions, chloride ions, bromide ions, iodide ions, such as chloride ions, bromide ions, iodide ions, such as chloride ions and bromide ions, such as chloride ions.

[0097] The XL component can react with the polylysine component. Members of the XL component can be prepared by a variety of methods. For example, to prepare an XL component having at least two XL1 groups, a polyamine or diamine (e.g., isophorone diamine) and solid phosgene are dissolved separately in a suitable organic solvent; then, the polyamine or diamine solution is added dropwise to the phosgene solution at room temperature or up to 40°C, and the reaction time is typically 2 to 7 hours; after the reaction is complete, the product is distilled to obtain the XL component having at least two XL1 groups.

[0098] Examples of XL components include, but are not limited to, monomeric diisocyanates, monomeric polyisocyanates, isocyanate-functionalized polyurethanes, and isocyanurate trimers of diisocyanates (e.g., isocyanurate trimers of 1,6-hexamethylene diisocyanate, isocyanurate trimers of isophorone diisocyanate, isocyanurate trimers of toluene diisocyanate, and isocyanurate trimers of methylene diphenyl diisocyanate).

[0181] Chemicals, raw materials and other materials used in the examples SEWON L-Lysine® (50 wt% L-lysine in water, lot number 181224) is supplied by Daesang and used as supplied. Desmodur® 44 V 20 L NP (pMDI) is a liquid dark brown polymeric isocyanate based on isomers and homologues of diphenylmethane-4,4'-diisocyanate with higher functionality (NCO content 30.5 wt%–32.5 wt%; viscosity at 25°C: 160 - 240 mPa·s; density at 20°C: 1.23 g / cm³). 3Desmodur® H (HDI) (Hexamethylene-1,6-diisocyanate; Molecular weight: 168 g / mol, Equivalent weight: 84; CAS No.: 822-06-0; NCO content: >49.6% wt%; Color value: <30 Hazen; Viscosity at 25°C: 3 mPa·s; Density at 20°C: 1.05 g / ml; Flash point: 135°C; Vapor pressure at 25°C: 1.4 × 10⁻⁶ -2 Desmodur® I (IPDI) (isophorone diisocyanate; molecular weight: 222 g / mol; equivalent weight: 111; CAS No.: 4098-71-9; NCO content: 37.4% wt%; color value: <30 Hazen; viscosity at 25°C: 10 mPa·s; density at 20°C: 1.06 g / ml; flash point: 150°C; vapor pressure at 25°C: 1.2 mPa·s) -3 D-(+)-glucose (anhydrous, 99% pure) was obtained from ThermoScientific (abbreviated as glucose). ε-polylysine (pale yellow powder, 99.4% pure) was supplied by Bonding Chemical. ε-polylysine has an M of 21301 Da as determined by the GPC method described in this specification. n 22061 Da of M w and polydispersity (PD) of 1.04 (=M) w / M n The apparent viscosity was 32480 mPa·s, as determined by the rheological method described in this specification. This polylysine is mentioned as PLL-2C in the examples and is not based on the claimed invention. The object (fiberboard; FB) shown in the examples was prepared using wood chips having a water content of 2.7 wt%, a density of 240 kg / m³, and a d50 (median particle size distribution of wood chips; according to ISO 17827-1:2016) of 4.5 mm.

[0182] Preparation of polylysine components 1.1.1 Hyperbranched polylysine 1 (abbreviated as PLL-1) The preparation of hyperbranched polylysine 1 (PLL-1) was carried out as follows: 6254 g of SEWON L-Lysine® was added to a 10-liter glass reactor equipped with a distillation apparatus at room temperature. The temperature in the reactor was then slowly (over 4 hours) raised to 105°C (this slow temperature increase is necessary to avoid precipitation of unreacted L-lysine in the reactor, which may occur if too much water is distilled off before full reaction and conversion). Once the temperature in the reactor reached 105°C, water distillation began. The reactor temperature was then slowly raised to 160°C. When the reaction reached 130°C, 2610 g of SEWON L-Lysine® was slowly added to the reactor at the same rate as the distilled water. The temperature was then maintained at 160°C for 1 hour. After 1 hour at 160°C, a vacuum of 100 mbar was slowly applied until the apparent viscosity of the reactor contents, as determined by rheological analysis as disclosed in the specification, reached 1300 mPa·s. Once an apparent viscosity of 1300 mPa·s was achieved, the temperature in the reactor was then reduced to 90°C, and water was metered into the reactor to achieve a solid content of 60 ± 1% by weight. The final product – hyperbranched polylysine 1 (PLL-1) – was obtained as a brown solution in water.

[0183] Characterization of hyperbranched polylysine 1 (PLL-1): DB: 0.43 [D = 18.2 (integrated at 4.15–4.40 ppm); Lα = 9.3 (integrated at 3.90–4.10 ppm); Lε = 47.4 (integrated at 3.25–3.30 ppm)], gel content: 0.0%; M n 2250 Da, M w : 10609 Da, polydispersity (PD) (=M w / M n ): 4.72, Amine value (AN): 386 mgKOH / g, Acid value (AV): 33 mg KOH / g (three ERC peaks were recorded in the titration method), Apparent viscosity: 1300 mPa.s.

[0184] 1.1.2. Hyperbranched polylysine 3 (PLL-3C) The preparation of hyperbranched polylysine 3 (PLL-3C) was carried out as follows: 3400 g of SEWON L-lysine® was added to a 5 L-pressure reactor equipped with a distillation apparatus connected to the reactor via a pressure relief valve (referred to herein as the "PR valve"). Once all the SEWON L-lysine® had been added to the reactor, the PR valve was closed. The temperature inside the reactor was then slowly (over 2 hours) increased to 130°C for approximately 2 hours, and the pressure was brought to 3.5 bar. Once the temperature in the reactor reached 130°C, the PR valve was carefully opened to allow distillation of water; the reactor temperature was maintained at 130°C until the solids content was 82 ± 1% by weight. During this stage, and to maintain the mass of approximately 3400 g in the reactor, SEWON L-lysine® was pumped into the reactor at the same rate as the distilled water. Once a solids content of 82 ± 1% by weight was achieved (at which point the pressure in the reactor decreased from 3.5 bar to 1.2 bar), the PR valve was closed. Subsequently, the temperature and pressure in the reactor were increased to 190°C and 5 ± 0.5 bar, respectively. During this stage, the temperature and pressure in the reactor were maintained at 190°C and 5 ± 0.5 bar, respectively, until the apparent viscosity of the reactor contents (as measured in the instructions) reached 4800 mPa·s; during this stage, the pressure in the reactor was maintained at 5 ± 0.5 bar by periodically and carefully distilling out water through the PR valve. Once the apparent viscosity of 4800 mPa·s was achieved, the temperature in the reactor was reduced to 90°C, and water was metered into the reactor to achieve a solid content of 60 ± 1% by weight. The final product – hyperbranched polylysine 3 (PLL-3C) – was obtained as a brown solution in water.

[0185] Characterization of hyperbranched polylysine 3 (PLL-3C): DB: 0.27 [D = 12.45 (integral at 4.15–4.40 ppm); Lα = 19.38 (integral at 3.90–4.10 ppm); Lε = 42.76 (integral at 3.25–3.30 ppm)], gel content: 5.0%, M n : nm Da (insoluble), M w :nm Da (insoluble), polydispersity (PD) (=M w / M n ): nm, Amine value (AN): 213 mg KOH / g, Acid value (AV): 52 mg KOH / g (three ERC peaks were recorded in the titration method), Apparent viscosity: 4900 mPa.s.

[0186] This polylysine is not based on the claimed invention.

[0187] 1.1.3 Comparison of the preparation methods of fiberboard and the invented fiberboard The comparative and inventive compositions shown in Table 1 were prepared as follows: a) The fiber component was placed in a planetary mixer without any mixing; b) The polylysine component was added to the fiber component and mixed within 60 seconds; c) The XL component was then added to the mixture of the polylysine component and the fiber component prepared in b); d) After the XL component was added, the mixture in step c) was mixed for 4 minutes.

[0188] By using a suitable hot press (e.g., Fontijne TP800) to achieve a pressing time factor of 19 sec / mm, the corresponding compositions were subjected to simultaneous heating (120°C) and pressure [50 kg / cm²]. 2 = 4903.325 kPa)] (hot pressing) to prepare the comparative and inventive objects, namely fiberboard, to form a board of 28 (L) x 34 (W) x 1.5 (T) cm (425 cm) 2 (surface area).

[0189] All fiberboards prepared and tested had a thickness of 15 mm ± 10%.

[0190] All fiberboards prepared and tested had a density of 700 kg / m³. 3 ± 10%.

[0191] The weight of the polylysine component shown in Table 1 is calculated based on the solid content of the polylysine component determined by the solid content method disclosed in the specification; therefore, the reported weight of the polylysine component shown in Table 1 corresponds to a solid content of 100% for the polylysine component.

[0192] The weights of the XL components shown in Table 1 are calculated based on the solids content reported by the supplier (see § 1.1); therefore, the reported weights of the XL components shown in Table 1 correspond to a solids content of 100% for the XL components.
