Description

Technical Field

[0001] This invention relates to a high-toughness, wear-resistant polyphenylene sulfide alloy material and its preparation method, belonging to the field of polymer composite materials technology. Background Technology

[0002] Polyphenylene sulfide (PPS), also known as polyphenylene sulfide, has good overall properties, including high temperature resistance, corrosion resistance, radiation resistance, non-flammability, and good mechanical and electrical properties. However, PPS has low impact strength and poor flexural strength; moreover, PPS melt viscosity is high, resulting in poor flowability and insufficient processing performance; and its cost is relatively high compared to general engineering plastics. These disadvantages limit the application range of PPS.

[0003] Patent CN111875963A uses polyphenylene sulfide resin, nylon 6 resin, mica powder, flat glass fiber, calcium sulfate whiskers, titanate coupling agent, ethylene-maleic anhydride-glycidyl methacrylate copolymer, 2,2'-(1,3-phenylene)-dioxazoline, N,N'-bis(2,2,6,6-tetramethyl-4-piperidinyl)-1,3-phenylenediamide, and bis(2,6-di-tert-butyl-4-

[0004] Polyphenylene sulfide / nylon 6 composite material was prepared by using pentaerythritol diphosphate (PPS) of methylphenylene(II) phosphate. The ability of amorphous molecular activity was suppressed by mineral and glass fiber fillers, and the low linear expansion coefficient of inorganic fillers was combined to make the PPS / PA6 alloy material have low linear expansion coefficient and low warpage characteristics.

[0005] Patent CN1272124A discloses a method for manufacturing polyphenylene sulfide (PPS) composite materials modified by blending zinc oxide whiskers and glass fibers or carbon fibers with polyphenylene sulfide (PPS) resin. The purpose is to use zinc oxide as a corrosion inhibitor to improve the corrosion resistance to metals and eliminate the adverse effects on mechanical and physical properties. However, after adding zinc oxide, the tensile strength and elongation at break of the injection-molded polyphenylene sulfide (PPS) composite material are reduced, and its impact strength is also reduced.

[0006] Although glass fiber reinforcement can significantly improve the rigidity and other mechanical properties of PPS, the modified material after reinforcement has poor processability, poor impact resistance, rough surface of the product, and too much loose fiber, which cannot well meet the injection molding, performance and appearance requirements of the parts.

[0007] In view of the above problems, this invention is proposed. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the first objective of the present invention is to provide a high-toughness and wear-resistant polyphenylene sulfide alloy material.

[0009] A second objective of this invention is to provide a method for preparing the aforementioned alloy material.

[0010] To achieve the first objective, the present invention is implemented through the following technical solution: a high-toughness and wear-resistant polyphenylene sulfide alloy material, comprising, by weight, 35-50 parts of polyphenylene sulfide, 25-45 parts of nylon, 5-15 parts of fiber composition, 5-10 parts of thermally conductive filler, 0.5-5 parts of compatibilizer, 0.5-5 parts of antioxidant, and the balance of coupling agent.

[0011] Preferably, based on 100 parts by weight, it includes 35-40 parts by weight of polyphenylene sulfide, 30-35 parts by weight of nylon, 10-15 parts by weight of fiber composition, 5-8 parts by weight of thermally conductive filler, 0.5-3 parts by weight of compatibilizer, 0.5-3 parts by weight of antioxidant, and the balance of coupling agent.

[0012] By adopting the above technical solution, adding fiber composition and thermally conductive filler can improve the thermal stability, mechanical strength and other performance indicators of the product. By adding fiber composition for reinforcement, the strength and impact performance of the material can be improved without losing thermal performance and stiffness. Adding thermally conductive filler can significantly improve the impact performance of composite materials, resulting in heat-resistant, wear-resistant and high-strength composite materials.

[0013] Preferably, the fiber composition comprises glass fiber and carbon fiber in a mass ratio of 1-2:2-5; the glass fiber is processed with β-(3,4-

[0014] The carbon fibers are impregnated with an epoxycyclohexyl(ethyltrimethoxysilane) surface treatment agent and then impregnated with glyoxal and chitosan.

[0015] Preferably, the glass fiber has a diameter of 15-30 μm and the carbon fiber has a length of 2-5 mm.

[0016] Preferably, the carbon fiber includes polyacrylonitrile-based carbon fiber, phenolic-based carbon fiber, and lignin-based carbon fiber, with a mass ratio of 3-5:1-3:1.

[0017] By adopting the above technical solution, glass fiber and carbon fiber are added to the composite material in combination, and the mechanical and thermodynamic properties of the alloy material are further optimized by adjusting the ratio of the two and the diameter of glass fiber and the length of carbon fiber.

[0018] Preferably, the thermally conductive filler is composed of alumina, aluminum nitride and silicon carbide in a mass ratio of 2-3:1-3:1.

[0019] Thermally conductive fillers, as the name suggests, are fillers added to matrix materials to increase the thermal conductivity of the materials. Commonly used thermally conductive fillers include alumina, magnesium oxide, zinc oxide, aluminum nitride, boron nitride, and silicon carbide. Among them, micron-sized alumina and silicon micro powder are the main components, while nano-alumina and nitrides are used as filler powders in the field of high thermal conductivity. Zinc oxide is mostly used as a filler in thermal paste (thermal grease).

[0020] Preferably, the antioxidant comprises one or more of pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], tris[2,4-di-tert-butylphenyl]phosphite, and 1,3,5-tris(4-tert-butyl-3-hydroxy-2,6-dimethylbenzyl)-1,3,5-triazine-2,4,6-(1H,3H,5H)-trione.

[0021] The antioxidant used in this invention is designed to eliminate oxygen molecules inside the material, thereby further preventing the polyphenylene sulfide resin from discoloring at high temperatures.

[0022] Preferably, the compatibilizer is maleic anhydride or maleic anhydride graft.

[0023] SEBS, maleic anhydride-grafted styrene or maleic anhydride-grafted ethylene

[0024] Octene copolymer; the coupling agent is a silane coupling agent, titanate coupling agent, aluminate coupling agent or polymeric coupling agent.

[0025] To achieve the second objective, the present invention provides a method for preparing a high-toughness, wear-resistant polyphenylene sulfide alloy material, comprising the following steps:

[0026] S1: The polyphenylene sulfide, nylon, fiber composition, thermally conductive filler, compatibilizer, antioxidant and coupling agent are dried;

[0027] S2: Glass fibers are processed through β-(3,4-

[0028] The carbon fiber is impregnated with epoxycyclohexyl(ethyltrimethoxysilane) surface treatment agent for 0.5-1h, and impregnated with glyoxal and chitosan for 1-2h.

[0029] S3: The treated glass fiber and carbon fiber are mixed with a coupling agent, and then other components are added to a high-speed mixer for mixing to obtain a premix.

[0030] S4: The premix is ​​fed into a twin-screw extruder for melt mixing and then extruded and granulated to obtain the alloy material.

[0031] Preferably, in step S4, the screw speed is 250-600 r / min and the barrel temperature is 200-300℃.

[0032] The beneficial effects of this invention are:

[0033] (1) The alloy material of the present invention has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability and excellent electrical properties of polyphenylene sulfide and high mechanical strength, high temperature resistance and low water absorption of nylon. By adding fiber composition to the alloy material for reinforcement, the strength and impact performance of the material are improved.
