Description

[Technical Field] 【0001】 The present invention relates to a mineral fiber product comprising mineral fibers in contact with a binder resulting from the curing of an aqueous binder composition that does not contain phenol and formaldehyde. [Background technology] 【0002】 Mineral fiber products generally include man-made vitreous fibers (MMVF), such as glass fibers, ceramic fibers, basalt fibers, slag wool, mineral wool, and stone wool, which are bonded together by a cured thermosetting polymer binder material. For use as thermal insulation or soundproofing products, bonded mineral fiber mats are usually manufactured by converting a molten material made from suitable raw materials into fibers using conventional methods, such as a spinning cup process or a cascade rotor process. The fibers are blown into a molding chamber, and while still hot and in the air, a binder solution is sprayed onto them, and they are randomly deposited on a moving conveyor as mats or webs. The fiber mats are then transferred to a curing oven, where heated air is blown into the mats to cure the binder and firmly bond the mineral fibers. 【0003】 In the past, the selected binder resin was phenol-formaldehyde resin, which can be economically manufactured and extended with urea before use as a binder. However, in consideration of existing and proposed laws regarding the reduction or elimination of formaldehyde emissions, formaldehyde-free binders have been developed, such as polycarboxypolymer and polyol or polyamine-based binder compositions disclosed in, for example, European Patent Publication No. 583086, European Patent Publication No. 990727, European Patent Publication No. 1741726, U.S. Patent No. 5,318,990, and U.S. Patent Publication No. 2007 / 0173588. 【0004】 Another group of non-phenol-formaldehyde binders are addition / elimination reaction products of aliphatic anhydrides and / or aromatic anhydrides with alkanolamines, as disclosed, for example, in International Publication No. 99 / 36368, International Publication No. 01 / 05725, International Publication No. 01 / 96460, International Publication No. 02 / 06178, International Publication No. 2004 / 007615 and International Publication No. 2006 / 061249. These binder compositions are water-soluble and exhibit excellent binding properties in terms of curing rate and curing density. International Publication No. 2008 / 023032 discloses a urea-modified binder of its type that provides mineral wool products with reduced water absorption. 【0005】 Since some of the starting materials used in the manufacture of these binders are fairly expensive chemicals, there is an ongoing need to provide formaldehyde-free binders that can be manufactured economically. 【0006】 A further benefit of previously known aqueous binder compositions from mineral fibers is that at least a large portion of the starting materials used in the manufacture of these binders are derived from fossil fuels. The consumer trend towards products manufactured entirely or at least partially from renewable materials continues, and therefore, there is a need to provide binders for mineral wool that are manufactured at least partially from renewable materials. 【0007】 A further consequence of previously known aqueous binder compositions for mineral fibers is that they contain corrosive and / or harmful components. This necessitates protective measures for machinery involved in the manufacture of mineral wool products to prevent corrosion, and also requires safety measures for the people handling this machinery. This leads to increased costs and health problems, and therefore there is a need to provide binder compositions for mineral fibers with reduced content of corrosive and / or harmful materials. 【0008】 A further effect related to binder compositions for mineral fibers known from the prior art is that the curing of the binder composition during the production process of mineral wool products bonded by the binder may involve the release of undesirable substances that require emission control and contribute to an increase in the complexity of the machinery involved in production and an increase in costs. 【0009】 In recent years, many binders for mineral fibers based to a significant extent on renewable starting materials have been provided. In many cases, these binders, which are based to a significant extent on renewable resources, are also formaldehyde-free. 【0010】 However, many of these binders are still relatively expensive because they are based on relatively costly basic materials. 【0011】 On the other hand, binders for mineral fibers based on oxidized lignin components have been provided in order to be suitable as components of binder compositions for mineral wool. Very good binding properties are achieved by these mineral wool binders based on pre-oxidized lignin, but the preparation of such binders still requires an additional step of oxidizing the lignin component before the lignin component can be used as a component for the binder composition. This preliminary oxidation step required to utilize the lignin component complicates the production process of such binders to some extent by increasing the reaction time and decreasing the output (production rate), and increases the cost of such binders due to the additional costs for raw materials, process equipment and personnel allocation. 【Prior Art Documents】 【Patent Documents】 【0012】 【Patent Document 1】 European Patent Application Publication No. 583086 【Patent Document 2】 European Patent Application Publication No. 990727 【Patent Document 3】 European Patent Application Publication No. 1741726 [Patent Document 4] U.S. Patent No. 5,318,990 [Patent Document 5] U.S. Patent Application Publication No. 2007 / 0173588 [Patent Document 6] International Publication No. 99 / 36368 pamphlet [Patent Document 7] International Publication No. 01 / 05725 Pamphlet [Patent Document 8] International Publication No. 01 / 96460 Pamphlet [Patent Document 9] International Publication No. 02 / 06178 Pamphlet [Patent Document 10] International Publication No. 2004 / 007615 Pamphlet [Patent Document 11] International Publication No. 2006 / 061249 Pamphlet [Patent Document 12] International Publication No. 2008 / 023032 Pamphlet [Overview of the project] [Problems that the invention aims to solve] 【0013】 Accordingly, the object of the present invention was to provide a mineral wool product comprising mineral fibers in contact with a binder resulting from the curing of a binder composition suitable for binding mineral fibers, which can be manufactured inexpensively using renewable materials as starting materials, reducing or eliminating corrosive and / or harmful materials. 【0014】 A further object of the present invention was to provide a mineral wool product comprising mineral fibers in contact with a binder resulting from the curing of a binder composition suitable for binding mineral fibers, which enables an increased solids content (and thus reduced transport costs and less environmental impact), reduced viscosity (which makes processing on a large scale easier), and a longer shelf life. 【0015】 Furthermore, the present invention provides the use of a lignin component for the preparation of a binder composition for mineral wool. [Means for solving the problem] 【0016】 According to a first aspect of the present invention, • Component (i) in the form of lignosulfonate trinin having a carboxylic acid group content of 0.03 to 2.0 mmol / g, for example 0.03 to 1.4 mmol / g, for example 0.075 to 2.0 mmol / g, for example 0.075 to 1.4 mmol / g based on the dry weight of the lignosulfonate trinin, • One or more crosslinking agents as components (ii) A mineral fiber product is provided which includes mineral fibers in contact with a binder resulting from the curing of an aqueous binder composition that does not contain phenol and formaldehyde, which contains the above. 【0017】 In particular, according to the first aspect of the present invention, • Component (i) in the form of lignosulfonate trinin having a carboxylic acid group content of 0.03 to 2.0 mmol / g, for example 0.03 to 1.4 mmol / g, for example 0.075 to 2.0 mmol / g, for example 0.075 to 1.4 mmol / g based on the dry weight of the lignosulfonate trinin, • One or more crosslinking agents as components (ii) A mineral fiber product containing mineral fibers in contact with an aqueous binder composition, preferably an aqueous binder composition that does not contain phenol and formaldehyde, which is obtained from the curing of such a binder, provided that the aqueous binder composition is • Molecular weight M of 500 or less W epoxy compounds having ·Formula R-[C(O)R1] x A carbonyl compound selected from the aldehyde and carbonyl compounds, wherein in the above formula, R represents a saturated or unsaturated linear, branched, or cyclic hydrocarbon group, a group containing an aromatic nucleus consisting of one or more 5 or 6 carbon atoms, or a group containing an aromatic heterocycle containing one or more 4 or 5 carbon atoms and an oxygen atom, a nitrogen atom, or a sulfur atom, and this R group may contain other functional groups. R1 is a hydrogen atom or C1~C 10 Represents an alkyl group, x is a carbonyl compound in the range of 1 to 10. • Polyamines, Monosaccharides and oligosaccharides Mineral fiber products that do not contain crosslinking agents selected from are provided. 【0018】 The inventors have surprisingly found that it is possible to provide mineral wool products containing mineral fibers bound by a binder resulting from the curing of a binder composition that can be manufactured from an inexpensive, renewable material in the form of a lignin component. This lignin component does not require an oxidation process prior to use in the binder composition and contains little to no corrosive or harmful substances. 【0019】 The inventors have surprisingly found that it is possible to provide mineral wool products containing mineral fibers bound by a binder resulting from the curing of a binder composition that requires only two main components in the simplest form, a lignin component and a crosslinking agent, or three main components in the form of a lignin component, a crosslinking agent, and a plasticizer. This reduction in the complexity of the binder composition compared to previously known multi-component systems reduces the complexity of the supply chain, facilitates the handling of storage capacity, and improves the storability of the binder. All of these factors contribute to the economic advantages of the binder composition according to the present invention.

Preferably, the test is carried out in accordance with ISO 16000 for testing aldehyde emissions. 【0036】 In a preferred embodiment, the binder does not contain phenol. 【0037】 For the purposes of this application, the terms “phenol-free” and “phenol-free” are defined as an aqueous binder composition containing phenol in an amount of 0.25% by weight or less, for example 0.1% by weight or less, for example 0.05% by weight or less, based on the total weight of the aqueous composition having a dry solids binder content of 15% by weight. [ka] 【0038】 In one embodiment, the binder composition does not contain added formaldehyde. 【0039】 In one embodiment, the binder composition does not contain added phenol. 【0040】 For the purposes of this invention, the term "monosaccharides and oligosaccharides" is defined to include monosaccharides and oligosaccharides having 10 or fewer sugar units. 【0041】 For the purposes of this invention, the term "sugar" is defined to include monosaccharides and oligosaccharides having 10 or fewer sugar units. 【0042】 Ingredient (i) Component (i) is one or more lignosulfonate lignins, in the form of lignosulfonate lignins having a carboxylic acid group content of 0.03 to 2.0 mmol / g, for example 0.03 to 1.4 mmol / g, for example 0.075 to 2.0 mmol / g, for example 0.075 to 1.4 mmol / g based on the dry weight of the lignosulfonate lignin. 【0043】 Lignin, cellulose, and hemicellulose are the three main organic compounds in plant cell walls. Lignin can be thought of as an adhesive that holds cellulose fibers together. Lignin contains both hydrophilic and hydrophobic groups. Lignin is the second most abundant natural polymer in the world, second only to cellulose, and is estimated to account for about 20-30% of the total carbon contained in biomass totaling over 1 billion tons. 【0044】 The lignosulfonate process introduces a large number of sulfonate groups to make lignin soluble not only in water but also in acidic aqueous solutions. Lignosulfonates contain up to 8% sulfur as sulfonates, while Kraft lignin contains 1-2% sulfur, most of which is bound to the lignin. The molecular weight of lignosulfonates is 15,000-50,000 g / mol. The typical hydrophobic core of lignin, along with numerous ionized sulfonate groups, makes this lignin attractive as a surfactant, and lignin often finds applications in dispersing cement and other materials. 【0045】 To produce value-added lignin-based products, lignin must first be separated from biomass, and several methods can be used for this purpose. Kraft and sulfite pulping processes are well-known for their effective separation of lignin from wood and are therefore used worldwide. Kraft lignin is separated from wood with the help of NaOH and Na2S. Lignin from the sulfite pulping process is expressed as lignosulfonate and is produced by using sulfites containing sulfite and / or magnesium, calcium, sodium, or ammonium at various pH levels. Currently, lignosulfonate accounts for 90% of the entire market for commercially available lignin, and the total annual global production of lignosulfonate is approximately 1.8 million tons. Lignosulfonate generally has abundant sulfonic acid groups and therefore contains more sulfur than kraft lignin. Due to the presence of sulfonating groups, lignosulfonate is anionically charged and water-soluble. The molecular weight (Mw) of lignosulfonate can be similar to or greater than that of kraft lignin. Due to its unique properties, lignosulfonates have a wide range of applications, including animal feed, insecticides, surfactants, additives in oil drilling, stabilizers in colloidal suspensions, and plasticizers in concrete admixtures. However, most new pulp mills employ kraft technology for pulp production, and therefore kraft lignin is more readily available for value-added production. 【0046】 However, lignosulfonates and Kraft lignin have different properties due to different isolation processes and therefore different functional group distributions. The high level of sulfonic acid groups in lignosulfonates, generally at least one for every four C9 units, makes lignosulfonates strongly charged at all pH levels in water. This abundance of ionizable functional groups can explain most of the differences compared to other industrial lignins. The higher charge density allows for easier water solubility and a higher solids content in solution compared to Kraft lignin. Also for the same reason, lignosulfonates have a lower solution viscosity compared to Kraft lignin at the same solids content, which can make them easier to handle and process.

[Examples] 【0190】 In the following examples, several binders that fall under the definition of the present invention were prepared and compared with binders according to the prior art. 【0191】 The following characteristics were measured for the binder according to the present invention and the binder according to the prior art. 【0192】 Binder component solid content The content of each component in a given binder solution before curing is based on the anhydrous mass of the component. 【0193】 Lignosulfonates were supplied by Borregaard, Norway and LignoTech, Florida, as liquids with approximately 50% solids content. Primid XL552 was supplied by EMS-CHEMIE AG. Silane (Momentive VS-142 40% active) was supplied by Momentive and was calculated as 100% for simplicity. NH4OH 24.7% was supplied by Univar and used in the supplied form. PEG200, urea, KOH pellets, and 1,1,1-tris(hydroxymethyl)propane were supplied by Sigma-Aldrich and used as is, assumed to be anhydrous for simplicity. 【0194】 Binder solids The contents of the binder after hardening are called "binder solids." 【0195】 Disk-shaped stone wool samples (5 cm in diameter; 1 cm in height) were cut from the stone wool and heat-treated at 580°C for at least 30 minutes to remove all organic matter. The solid content of the binder mixture was measured by distributing a sample of the binder mixture (approximately 2 g) onto the heat-treated stone wool discs in a tin foil container. The weight of the tin foil containers containing the stone wool discs was weighed before and immediately after the addition of the binder mixture. Two stone wool discs were prepared by filling the tin foil containers with such binder mixtures, and then heated at 200°C for 1 hour. After cooling and storage at room temperature for 10 minutes, the samples were weighed and the binder solid content was calculated as the average of the two results. 【0196】 Next, a binder having the desired binder solid content could be produced by diluting it with the required amount of water and a 10% silane aqueous solution (Momentive VS-142). 【0197】 mechanical strength research Bar test The mechanical strength of the binders was tested using a bar test. For each binder, 16 bars were produced from a mixture of the binder and stone wool shots from stone wool spinning production. 【0198】 A sample (16.0 g) of this binder solution having 15% dry solids was thoroughly mixed with a shot (80.0 g). The resulting mixture was then filled into four slots (4 x 5 slots / foam; slot top dimensions: length = 5.6 cm, width = 2.5 cm; slot bottom dimensions: length = 5.3 cm, width = 2.2 cm; slot height = 1.1 cm) of heat-resistant silicone form for making small bars. The mixture in the slots was then pressed with a flat metal bar of the appropriate size to produce a uniform bar surface. Sixteen bars were made in this manner from each binder. The resulting bars were then cured typically at 225°C. The curing time was 1 hour. After cooling to room temperature, the bars were carefully removed from the container. Five of these bars were aged in a water bath at 80°C for 3 hours. This method of curing the prepared bars was used in the examples in Table 1. 【0199】 After drying for 3 days, a three-point bending test was conducted using a Bent Tram machine (test speed: 10.0 mm / min; bursting level: 50%; nominal strength: 30 N / mm²). 2 Support distance: 40 mm; Maximum deflection: 20 mm; Nominal modulus of elasticity (nominal e-module): 10,000 N / mm 2 In the experiment, aged bars and five unaged bars were destroyed to examine their mechanical strength. The bars were placed in the machine with the "top surface" (i.e., the side with dimensions of length = 5.6 cm and width = 2.5 cm) facing upwards. 【0200】 Examples of binders, reference binders (urea-modified phenol-formaldehyde resin, PUF-resol) This binder is urea-modified phenol-formaldehyde resin, PUF-resol. 【0201】 The phenol-formaldehyde resin is prepared by reacting 606 g of a 37% formaldehyde aqueous solution and 189 g of phenol in the presence of 25.5 g of a 46% potassium hydroxide aqueous solution at a heating rate of approximately 1°C per minute, reaching a reaction temperature of 84°C. This reaction is continued at 84°C until the resin's acid resistance reaches 4 and most of the phenol is converted. Then, 241 g of urea is added, and the mixture is cooled. 【0202】 Acid tolerance (AT) represents the number of times a given amount of binder can be diluted with acid without the mixture becoming cloudy (the binder precipitating). Sulfuric acid is used to determine the termination criteria in binder manufacturing, and an acid tolerance of less than 4 indicates the end of the binder reaction. 【0203】 To measure AT, prepare a titrant by diluting 2.5 ml of concentrated sulfuric acid (>99%) with 1 L of deionized water. Then, titrate 5 mL of the binder to be examined with this titrant at room temperature, keeping the binder moving by manual shaking. If preferred, use a magnetic stirrer and magnetic stirring rod. Continue titration until a slight cloudiness appears on the binder that does not disappear when the binder is shaken. 【0204】 Acid resistance (AT) is calculated by dividing the amount of acid (mL) used in the titration by the amount of sample (mL). AT = (Titration volume used (mL)) / (Sample volume (mL)) 【0205】 Using the obtained urea-modified phenol-formaldehyde resin, a binder is prepared by adding 25% aqueous ammonia (90 mL) and ammonium sulfate (13.2 g), followed by the addition of water (1.30 kg). 【0206】 Next, the binder solids content was measured as described above, and this mixture was diluted with the necessary amount of water and silane for mechanical measurement (15% binder solids solution, 0.5% silane of binder solids). 【0207】 Examples 1-7 In the following examples, the entry numbers for the binders correspond to the entry numbers used in Table 1. 【0208】 The carboxylic acid group content of all lignosulfonates used in the binder according to the present invention is: 31 Measurements using 1P NMR revealed that the concentration ranged from 0.05 to 0.6 mmol / g based on the dry weight of lignosulfonate lignin, but for this particular batch used in Examples 1, 2, 3, 4, 5, 6, and 7, it was found to be 0.14 mmol / g. 【0209】 Example 1 30.0 g of lignosulfonate solution (50% solids) was mixed with 0.4 g of NH4OH (24.7%), followed by the addition of 0.7 g of silane (Momentive VS-142, 40% active, 10% aqueous solution), and then 68.9 g of water. The mixture was then mixed to obtain a 15% solids solution, which was subsequently used for testing the mechanical properties in a bar test. 【0210】 Example 3 30.0 g of lignosulfonate solution (50% solids) was mixed with 0.4 g of NH4OH (24.7%), followed by the addition of 6.0 g of Primid XL552 (100% solids) and mixing. Finally, 1.0 g of silane (Momentive VS-142 40% active, 10% aqueous solution) and 102.6 g of water were added and mixed to obtain a 15% solids solution, which was then used for mechanical property testing in a bar test. 【0211】 The mechanical properties are shown in Table 1. For simplicity, the amounts of all other components are recalculated based on 100g of dry lignin. 【0212】 As can be seen from Table 1, in the combination of lignosulfonate and crosslinking agent (Primid XL552), a larger amount of crosslinking agent results in better mechanical properties. 【0213】 [Table 1] 【0214】 Examples 5-7: Testing of stone wool products The properties of the low-density products were examined in accordance with DS / EN13162:2012+A1:2015, which represents the product standards for factory-manufactured mineral wool (MW) products, and the relevant mechanical and other basic properties of stone wool products. 【0215】 This test was performed on thick plates, and for each of the different test methods, specimens were cut according to the dimensional specifications and the number of specimens required to obtain one test result, as described in EN13162. Each of the values ​​described for the obtained mechanical properties is the average of more results according to EN13162. 【0216】 The tests are performed on products or test specimens sampled directly from the production line before packaging (line cuts) and / or products or test specimens sampled from the packaged product 24 hours after packaging (24-hour packs). 【0217】 size The dimensions of the products and test specimens were determined in accordance with the relevant test methods DS / EN822:2013:Thermal insulating products for building applications - Determination of length and width, and DS / EN823:2013:Thermal insulating products for building applications - Determination of thickness. 【0218】 Binder content (ignition loss) The binder content was determined according to DS / EN13820:2003: Thermal insulating materials for building applications - Determination of organic content. In this test, the binder content was defined as the amount of organic material burned out at a given temperature (500±20℃) as specified in the standard. In the test, a temperature (590±20℃, for at least 10 minutes until a certain mass was reached) was used to ensure that all organic material was burned out. The loss on ignition was determined using at least 10g of wool corresponding to 8 to 20 cutouts (minimum 8 cutouts), which were evenly distributed throughout the test specimen using a cork borer to ensure that the entire thickness of the product was included. The binder content was defined as the LOI (Liquid Intake). The binder included oil and other binder additives. 【0219】 Tensile strength The tensile strength of low-density products was determined according to EN1608:2013: Thermal insulating products for building applications - Determination of tensile strength parallel to faces. Tensile strength was measured for test specimens from line cuts and 24-hour packs. 【0220】 Self-flexing (f70) Self-deflection is measured according to an internal test method for determining the deflection caused by the net weight of the product. A test specimen with a length of 990±10 mm and a width of a minimum of 270±5 mm and a maximum of 680±5 mm is placed horizontally on two supports (inclined tables) and two movable support devices with a mutual center distance of (700±2) mm. Self-deflection is measured at the center of the specimen and recorded either mechanically or electrically (transducer with display), and read on either a scale or a digital display. If the original product is longer than 990±10 mm, the excess length is trimmed. Self-deflection is measured on both sides of the test specimen. The measurement accuracy is ±0.2 mm for self-deflection < 10 mm and ±1 mm for self-deflection > 10 mm. 【0221】 Self-deflection is reported as (f70, 70cm span) = (f1 + f2) / 2mm, where f1 is the measurement when surface 1 is facing upwards, and f2 is the measurement when surface 2 is facing upwards. 【0222】 Tests will be performed on test specimens from line cuts and test specimens from 24-hour packs. 【0223】 Example 5 The stone wool product was manufactured using the binder described in Example 5, at a curing oven temperature set to 275°C. 【0224】 730.0 kg of ammonium lignosulfonate was placed in a mixing vessel, to which 8.5 L of NH4OH (24.7%) was added and stirred.
