Problems solved by technology

At the same time, because there are a large number of benzene rings in the main chain of PPS, and the degree of crystallinity is very high, its elongation at break is low, and its toughness and impact resistance are also poor, which limits its application to a certain extent.
[0004] In view of this, it is necessary to develop a PPS / PS composite material and its products to solve the problems of poor fluidity and poor impact resistance of the current PPS / PS composite materials.

Abstract

The invention provides a fiber reinforced PPS / PS composite material and a product thereof. The fiber reinforced PPS / PS composite material comprises the following materials by weight: thermoplastic resin, which includes 35 to 50 parts of PPS polymer and 0.1 to 10 parts of PS resin; a reinforced filling material, which includes 40 to 60 parts of flat envelope glass fiber and 0.5 to 2 parts of a granular glass filling material; and 0.5 to 2 parts of a compatilizer. According to the fiber reinforced PPS / PS composite material and the product thereof, PPS resin, the flat envelope glass fiber and fibrous filling materials except the flat envelope glass fiber are used as a matrix, the PS resin and hollow glass beads are added, and through addition of the PS resin and compatibilization of the compatilizer, fluidity and impact strength are improved, so a reinforced composite resin composition with higher mechanical strength, higher fluidity and lower warping performance is formed.

Description

【Technical field】 [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a fiber-reinforced PPS / PS composite material and a product thereof. 【Background technique】 [0002] Polyphenylene sulfide (PPS) is also known as polyphenylene sulfide and poly(sub)phenylene sulfide. PPS is a lightweight, high-performance material I1 developed by Philips Petroleum Company in 1967, industrialized production began in the 1970s, and put on the market under the trade name "Ryton"; it is following polyamide (PA), polyoxymethylene (POM ), polycarbonate (PC), modified polyphenylene oxide (MPPO), polybutylene methacrylate (PBT), and is recognized as the sixth largest engineering plastic. As the matrix of high-performance resin-based composite materials, PPS is receiving more and more attention in the application of electronics, automobiles, precision machinery, aerospace and military equipment. [0003] The chain link structural unit of PPS is ve...
