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 / ABS composite material and its products to solve the problems of poor fluidity, low elongation at break and poor impact resistance of the current PPS / ABS composite material.

Abstract

The invention discloses a high-fluidity fiber reinforced PPS / ABS composite material and a product thereof. The composite material comprises: by weight, thermoplastic resin comprising 35-50 parts of PPS polymer and 0.1-10 parts of ABS resin; a reinforcing filling material comprising 40-60 parts of flat section glass fiber and 0.5-2 parts of a granular glass filling material; and 0.5-2 parts of a compatilizer. The PPS resin reinforced by the flat section glass fiber and the fibrous filling material except the flat section glass fiber is adopted as a substrate, the ABS resin and hollow glass beads are added, and the compatibilization effect of the added ABS resin with the compatilizer is used to increase the fluidity, the elongation at break and the impact strength, and a reinforced composite resin composition with high mechanical strength, high fluidity and low warp is formed.

Description

【Technical field】 [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high fluidity fiber reinforced PPS / ABS composite material and its products. 【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...
