Composite polyphenyl thioether material

Abstract

The invention provides a composite polyphenyl thioether material. The composite material consists of the following components by weight percent: 40-80% of polyphenyl thioether, 20-50% of glass fiber, 3-10% of an impact modifier, and 1-2% of an antioxidant. The composite polyphenyl thioether material has favorable impact property, heat resistance and higher comparative tracking index, at the same time, the composite polyphenyl thioether material has higher flowability, and the composite polyphenyl thioether material is suitable for manufacturing electrical and electronic products, mechanical products, automobile parts and other heat-resistant and corrosion-resistant products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyphenylene sulfide composite material. Background technique [0002] Polyphenylene sulfide (PPS), also known as polyphenylene sulfide and polyphenylene sulfide, is a new type of special engineering plastic that was first created and put into production by Phillips Petroleum Co of the United States in 1968. Due to its special molecular structure, it has many unique properties, mainly in: excellent thermal stability, chemical stability, dimensional stability, corrosion resistance, good bonding performance, excellent flame retardancy, good Electrical properties, blendable modification. At present, it has a wide range of applications in automobile manufacturing, electrical and electronic, chemical, instrumentation and aerospace industries. [0003] Due to the existence of a large number of benzene rings on the main chain of PPS, the rigidity of the material is increa...

Problems solved by technology

However, the impact toughness of the material has not been greatly improved, and the tracking index of the material itself is relatively low, generally less than 150V. In order to expand its application range, it is necessary to improve its impact performance and tracking index

[0004] Chinese patent CN1462771 uses nano-styrene-butadiene rubber to modify polyphenylene sulfide. This patent is mainly used for the preparation of pure glass fiber reinforced polyphenylene sulfide composite materials. Since the addition of rubber reduces the fluidity of the material, it is not suitable for thin-walled molding. parts

Similarly, Chinese patent CN1513914 proposes the use of olefin resin and polyphenylene sulfide to form a polyphenylene sulfide composition, which is also not suitable for the manufacture of thin-walled parts
