Abstract

The invention is suitable for the field of plastics compounding technologies, and provides a PPO / PA / HIPS (polyphenylene oxide / polyamide / high impact polystyrene) composite material and a preparation method thereof. The PPO / PA / HIPS composite material comprises the following components in parts by weight: 15-35 parts of polyphenyl ether, 45-65 parts of polyamide, 1-10 parts of impact-resistant polystyrene, 2-8 parts of a compatilizer, 2-5 parts of a flexibilizer A, 2-5 parts of a flexibilizer B, 0.1-0.5 part of main antioxygen, 0.1-0.5 part of auxiliary antioxygen and 0.1-2 parts of an additive. The PPO / PA / HIPS composite material provided by the invention has natural matte effect, good fluidity, and strong flexibility, better mechanical property, thermal performance, processability, creep resistance and size stability. The preparation method is simple in flow, reasonable and controllable in process conditions, and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of plastic composites, in particular to a PPO / PA / HIPS composite material and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPO) resin is a non-crystalline thermoplastic polymer, which has the characteristics of high strength, good rigidity, small specific gravity, good dimensional stability, excellent electrical insulation and creep resistance, but it has processing flow Poor performance, intolerant to organic solvents. [0003] Nylon (PA) is a crystalline polar polymer with good fluidity, easy processing, and good resistance to organic solvents, but it has disadvantages such as easy water absorption, poor dimensional stability, and heat resistance. [0004] The PPO / PA products currently on the market, due to the extremely poor compatibility between the two, have no obvious reinforcing effect. Therefore, most PPO / PA products use glass fiber or glass fiber and minerals as r...
