Description

Technical Field

[0001] This invention relates to the field of polymer technology, and more specifically, to a POE compatibilizer, a preparation method, and a high-performance PGA material. Background Technology

[0002] 3D printing technology has a wide range of applications, covering almost all sectors of manufacturing. In prototyping, 3D printing can quickly create product prototypes, helping designers and engineers verify the feasibility of their designs. In production applications, 3D printing technology has gradually shifted from prototyping to manufacturing, particularly in high-demand fields such as medical, aerospace, and automotive, where it has demonstrated enormous potential. For example, in the medical field, 3D printing can create personalized medical devices and implants; in the aerospace field, it can print complex parts and structural components.

[0003] 3D printing technology using biodegradable materials is a cutting-edge field that combines environmental protection with advanced manufacturing techniques. This technology utilizes biodegradable materials to construct three-dimensional solids through layer-by-layer stacking, and has broad application prospects and significant environmental benefits.

[0004] In recent years, with the increasing global awareness of environmental protection, the demand for biodegradable materials has experienced explosive growth. PGA (polyglycolic acid), as an important biodegradable material, has played a significant role in replacing traditional plastics and reducing environmental pollution, and its market size has continued to expand in recent years. It is predicted that the global PGA resin market will reach US$520 million by 2029 and is expected to continue growing at a CAGR of 26.7% in the coming years. The industrial production technology of PGA is relatively mature, mainly including glycolic acid (ester) polycondensation and glycolide ring-opening polymerization. With continuous technological advancements, the production cost of PGA has gradually decreased, and production capacity has continued to expand, providing strong support for its application in a wider range of fields. China's PGA industry has ushered in a period of rapid development. Several large-scale PGA projects have been launched, such as the 50,000-ton / year and 200,000-ton / year polyglycolic acid projects of Yulin Chemical Co., Ltd. of the State Energy Group. The implementation of these projects has not only promoted the rapid increase in PGA production capacity but also facilitated the improvement of the industrial chain and technological level. PGA also has excellent processability and can be synthesized and processed through various methods. PGA is chemically stable, but under specific conditions (such as water and microbial action), it can rapidly degrade, with the final degradation products being carbon dioxide and water, which are harmless to the environment. Its degradation rate is the fastest among biodegradable plastics, and it does not require special degradation conditions. Due to its excellent biocompatibility and degradability, PGA is widely used in the medical field, such as in surgical sutures, drug delivery systems, fracture fixation materials, and tissue engineering scaffolds. PGA degrades into water and carbon dioxide in the human body, therefore it does not cause rejection reactions. As a fully biodegradable plastic, PGA can replace traditional plastics in many applications, such as agricultural films, food preservation packaging, and bottle materials. Although PGA materials have a green label, its structural problems lead to material performance defects, resulting in significant limitations in its applications. How to solve the problems of low hardness, poor toughness, high brittleness, rapid crystallization, and poor flowability is a challenge we need to address in modified blending processing. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a POE compatibilizer and its preparation method, as well as a high-performance PGA material and its preparation method. By adding a crosslinking agent, a crosslinking aid, and carboxylated styrene-butadiene rubber powder, a POE compatibilizer with good hardness, resilience, and heat resistance is obtained. Then, the POE compatibilizer is used as the toughening base material for PGA material, resulting in a green and environmentally friendly high-performance PGA material with good rigidity, strength, impact resistance, toughness, flowability, and glass transition temperature.

[0006] Firstly, one of the objectives of this invention is to provide a POE compatibilizer material.

[0007] Specifically, the POE compatibilizer is made from raw materials comprising the following components, wherein the weight parts of each component are as follows, based on 100 parts by weight of POE material:

[0008]

[0009]

[0010] Preferably, the weight parts of each component are:

[0011]

[0012] The POE material used in this invention has unique hardness and Mooney coefficient, and its performance is further improved after interaction with crosslinking agents and crosslinking aids. POE materials meeting the above requirements include commercially available POE8467 products in the art.

[0013] Furthermore, the crosslinking agent is selected from organic peroxides, preferably from one or a combination of 2,4-di-tert-butyl peroxypropylbenzene (BIBP), 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane (DBPH), dicumyl peroxide (DCP), tert-butyl hydroperoxide (TBHP), tert-pentyl hydroperoxide (TAHP), benzoyl peroxide (BPO), tert-butyl peroxide (TBPB), and tert-pentyl peroxide (TAPB).

[0014] Furthermore, the crosslinking aid is selected from one or a combination of triallyl isocyanurate (TAIC), bismaleimide (BMI), and vinyltrimethoxysilane (VTMS).

[0015] It is worth mentioning that the compounds obtained by replacing one or two hydrogen atoms in the organic peroxides used in this invention with organic groups, when used in conjunction with crosslinking aids, can significantly improve the crosslinking degree of POE materials and enhance their physical properties. In particular, vinyltrimethoxysilane can also form silicon-oxygen bonds during the crosslinking process, further improving the material's heat resistance, weather resistance, and mechanical properties.

[0016] Furthermore, lubricant A is selected from one or a combination of polyethylene glycol, polyethylene, and silicone-based lubricants; preferably from one or a combination of polyethylene glycol, polyethylene wax, polytetrafluoroethylene, methyl silicone oil, and silicon powder. Due to the high viscosity of POE, lubricant A can reduce frictional heat generated between materials and between the POE material and the barrel during twin-screw extrusion, as this frictional heat can affect the cross-linking of the material.

[0017] Furthermore, the raw materials also include light stabilizers, which are selected from commonly used light stabilizers in the art, such as light stabilizer 622, light stabilizer UV329, light stabilizer UV577, and light stabilizer 944. In this invention, polymeric high molecular weight hindered amine light stabilizers are preferred; more preferably, a polymer of succinic acid and (4-hydroxy-2,2,6,6-tetramethyl-1-piperidinol) (light stabilizer 622) is preferred. The light stabilizer can be stably dispersed in the material and can effectively absorb or reflect ultraviolet light, preventing it from causing the breakage and degradation of the polymer chains, thereby extending the service life of the product. The amount of light stabilizer added is the conventional amount used in the art, and those skilled in the art can adjust it as needed.

[0018] Furthermore, the raw materials also include antioxidants; the antioxidants are selected from those commonly used in the art; hindered phenolic antioxidants are preferred in this invention, such as antioxidant 1010, antioxidant 1073, antioxidant 264, etc. Antioxidants can prevent cross-linking degradation of the material. The amount of antioxidant added is the conventional amount used in the art, and those skilled in the art can adjust it as needed.

[0019] Secondly, another objective of this invention is to provide a method for preparing POE compatibilizing materials, which is one of the objectives of this invention.

[0020] Specifically, the preparation method includes:

[0021] After mixing and extruding the above components according to the required amount, POE compatibilizer material is obtained.

[0022] More specifically, the preparation method includes:

[0023] POE material, crosslinking agent, crosslinking aid, carboxylated styrene-butadiene rubber powder, and lubricant A are mixed in a high-speed mixer for 1-3 minutes, then added to a twin-screw extruder and granulated under an extrusion process at a temperature of 180-200℃ and a main extruder speed of 50-150 rpm to obtain POE compatibilized material.

[0024] Thirdly, the objective of this invention is to provide a high-performance PGA material.

[0025] Specifically, the high-performance PGA material is prepared from the POE compatibilizer material, which is one of the objectives of this invention, and the following components. Based on 100 parts by weight of the PGA material, the weight parts of each component are as follows:

[0026]

[0027]

[0028] Preferably, the weight parts of each component are:

[0029]

[0030] Furthermore, the composite antioxidant is selected from a combination of hindered phenolic antioxidants and phosphite antioxidants; preferably, it is a combination of long-acting antioxidant 1010 and short-acting antioxidant 168; wherein the weight ratio of hindered phenolic antioxidants to phosphite antioxidants is 0.5–2, preferably 0.8–1. During production and use, POE compatibilizers are prone to oxidation reactions due to mechanical forces, light, and heat. These oxidation reactions damage the physical and chemical properties of cross-linked POE materials, such as reducing their strength, toughness, and heat resistance, leading to material aging. The aforementioned composite antioxidant can effectively inhibit these oxidation reactions, maintain performance stability, thereby improving the stability of cross-linked POE materials and ensuring that cross-linked POE products maintain good performance throughout their use.

[0031] Furthermore, lubricant B is selected from one or a combination of polyethylene glycol, polyethylene, and silicone-based lubricants; preferably polyethylene glycol. Because PGA material has high hardness and generates frictional heat rapidly and uncontrollably, the addition of lubricant B in this invention can reduce friction between the plastic and processing equipment, making the processing smoother and thus reducing energy consumption. In addition, in processes such as injection molding, the polyethylene glycol lubricant can effectively prevent plastic from adhering to the mold, making the product easier to demold. This not only improves production efficiency but also significantly enhances the surface quality of the product.

[0032] Furthermore, the raw materials also include a light stabilizer, which is selected from polymerizable high molecular weight hindered amine light stabilizers; preferably, it is a polymer of succinic acid and (4-hydroxy-2,2,6,6-tetramethyl-1-piperidinol) (light stabilizer 622). The light stabilizer can absorb ultraviolet light, quench singlet oxygen, and decompose hydroperoxides into inactive substances, thereby eliminating or slowing down photochemical reactions in the polymer under light radiation. Meanwhile, because the light stabilizer has a half-life, its effectiveness is affected by the environment, thermal history, and light intensity. During use, the environmental impact is significant, requiring secondary addition to achieve a stabilizing effect.

[0033] Furthermore, a fourth objective of this invention is to provide a method for preparing the high-performance PGA material, which is the third objective of this invention.

[0034] Specifically, the preparation method includes:

[0035] The above components are stirred and extruded according to the required amount to obtain high-performance PGA materials.

[0036] More specifically, the preparation method includes:

[0037] PGA material, POE compatibilizer, composite antioxidant, and lubricant B are placed in a high-speed mixer and stirred for 1 to 3 minutes at 30 to 50°C. Then, the mixture is added to a twin-screw extruder and extruded at 200 to 240°C and 200 to 350 rpm / min to obtain high-performance PGA material.

[0038] It is worth mentioning that during the processing of cross-linked POE-toughened PGA materials, the viscosity of the POE / PGA material increases significantly after melting due to the addition of POE compatibilizer, which can easily lead to increased load and current in the twin-screw extruder. To solve the above processing problems, lubricating materials are usually added to reduce friction between the material and the screw barrel, thereby improving material production efficiency. At the same time, a certain amount of composite antioxidants are added to improve the material's antioxidant effect, stability, and service life. Long-acting antioxidants are hindered phenolic antioxidants, such as 1010, antioxidant 1073, and antioxidant 264 commonly used in this field; short-acting antioxidants are phosphite antioxidants, such as phosphate esters 168, phosphate ester 618, and phosphate ester 626 commonly used in this field, which can capture free radicals to decompose peroxides to achieve antioxidant effects.

[0039] Finally, a fifth objective of the present invention is to provide the application of the high-performance PGA material of the third objective of the present invention.

[0040] Specifically, the high-performance PGA material provided by this invention can be used as a 3D printing material.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] 1. The POE used in this invention is primarily a random copolymer of ethylene and α-olefin (1-octene). This copolymer is obtained by polymerizing ethylene and α-olefin through the action of a metallocene catalyst. Ethylene and α-olefin undergo physical cross-linking through the crystallization of polyethylene segments, resulting in a thermoplastic elastomer with dual properties of plastic and rubber. This invention significantly improves the heat resistance temperature of POE through cross-linking. Cross-linked POE maintains stable properties at higher temperatures, is less prone to thermal degradation or deformation, and exhibits significantly improved tensile strength, tear strength, and other key mechanical properties. Simultaneously, cross-linking reduces permanent deformation and improves resilience and creep resistance. These improved properties make POE perform exceptionally well in applications requiring high mechanical stress.

[0043] 2. This invention utilizes POE material as a toughening agent for PGA material and carboxylated styrene-butadiene rubber powder as an intermediate medium. The carboxyl groups of the carboxylated styrene-butadiene rubber powder react with a large number of hydroxyl groups in the PGA material, thereby improving the interaction and significantly enhancing the compatibility of the material. The toughness and rigidity of the material are enhanced, and the brittleness is reduced, effectively broadening the application field of the material.

[0044] 3. This invention, through the addition of a crosslinking agent, crosslinking aid, light stabilizer, and carboxylated styrene-butadiene rubber powder via melt extrusion granulation, yields a crosslinked POE compatibilizer material with good hardness, resilience, and heat resistance. When combined with PGA material, the crystallinity of PGA material is significantly reduced, effectively improving the brittleness of PGA material, increasing its toughness, and effectively broadening its application areas. Simultaneously, it also significantly enhances the overall physical properties of PGA material, making it a better material for 3D printing.

[0045] 3. The POE compatibilizer material obtained by this invention contains a large number of long-chain ethylene segments. After cross-linking, it is melt-blended with PGA material. The polyglycolic acid monomers are connected by ester bonds. When mixed with POE material, the chain segments of PGA material are extended, the toughness of PGA material is improved, stress cracking is reduced, and the performance of the material is improved.

[0046] 4. Due to the high viscosity and narrow processing temperature range of extruded PGA materials, the addition of cross-linked POE materials can easily cause cross-linking of POE materials under the second heat history. The added lubricant can reduce the friction between materials and between the material and the barrel, reduce the generation of frictional heat, and prepare uniform high-performance PGA materials.

[0047] 5. The high-performance blended PGA material provided by this invention is an excellent new material with green and environmentally friendly characteristics, as well as excellent physical properties, high rigidity, strength and certain spinning effect. Its glass transition temperature can be increased from 30-60℃ to 50-90℃, which can be used as a material for 3D printing.

[0048] 6. In this invention, POE material is made into a masterbatch and then co-extruded with PGA material. Compared with directly co-extruded POE material with PGA material, the material performance is better. The main reason is that when POE material is directly co-extruded with PGA material, phase separation will occur between the materials due to differences in components and structures. Moreover, the physical properties of POE material will be significantly reduced after adding PGA material without treatment. Detailed Implementation
