Problems solved by technology

Due to the good crystallinity and poor toughening effect of traditional polyaryletherketone materials, they are generally used as matrix resins or as alloys with other resins.
For example, the patent CN107778769A "A Glass Fiber Reinforced PPS / PEEK Alloy and Its Preparation Process" discloses that PEEK is used as an alloy to disperse the same PPS, but due to the poor toughening effect of PEEK, it is still necessary to introduce other toughening agents to improve the impact strength of the material
Up to now, there has been no relevant patent publication on the modification of thermoplastic engineering plastics using polyaryletherketone materials as tougheners

Abstract

The invention discloses a high-toughness glass fiber reinforced polyphenylene sulfide composite material, and belongs to the technical field of PPS modified plastics. The high-toughness glass fiber reinforced polyphenylene sulfide composite material comprises the following components in parts by weight: 40 to 70 parts of polyphenylene sulfide resin, 30 to 50 parts of glass fibers, 3 to 10 parts of phenolphthalein polyether ketone, 0.3 to 0.6 part of a nucleating agent, 0.5 to 1 part of a dispersing agent and 0.1 to 0.3 part of a high-temperature lubricating agent. The impact strength of the composite material is greatly improved compared with that of a traditional flexibilizer, and meanwhile good flame retardant performance can be maintained.

Description

technical field [0001] The invention relates to the technical field of PPS modified plastics, in particular to a high-toughness glass fiber reinforced polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties. It is widely used in electronics, automobiles, machinery and chemical industries. There are a wide range of applications. In practical application, PPS usually needs to be reinforced by glass fiber to use PPS itself has low impact strength, and the product is brittle. During the modification process, a toughening agent needs to be added for toughening treatment. [0003] Generally speaking, commonly used toughening agents for PPS include ethylene-methyl acrylate-glyci...
