Abstract

The invention belongs to the technical field of macromolecular materials, and particularly, discloses a composite material of PPA and PPS and a preparation method thereof. The PPA and the PPS, which are used as main raw materials, are modified under a melting state in combination with a filling enhancer, a lubricating agent, an antioxidant and a coupling agent. The filling enhancer is added to improve the mechanical and thermal properties of the composite material, the lubricating agent is added to improve the processability of the composite material, the antioxidant is added to improve the stability of the PPA during processing, and the coupling agent is added to reinforce the bonding between the filling enhancer and matrix resin.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a composite material of polyphthalamide and polyphenylene sulfide and a preparation method thereof. parts etc. Background technique [0002] Polyphthalamide (PPA) is a semi-crystalline thermoplastic aromatic polyamide, commonly known as aromatic high-temperature nylon. PPA has excellent heat resistance, the long-term working temperature can be as high as 180°C, and the short-term temperature resistance can reach 290°C; at the same time, PPA has high modulus, high hardness, high cost performance, dimensional stability, low water absorption, etc. Due to its excellent performance, PPA has broad application prospects in many fields, but it also has the disadvantages of poor flame retardancy and low resin flow properties, which limit the application of PPA. [0003] Polyphenylene sulfide (PPS) is currently the largest amount of special engineering plastics, kno...
