Abstract

The invention relates to a high-strength polyphenylene sulfide composition. The high-strength polyphenylene sulfide composition is prepared from the following components in parts by weight: 15 to 50 parts of polyphenylene sulfide, 15 to 55 parts of glass fibers, 15 to 30 parts of titanium dioxide, 15 to 20 parts of calcium stearate, 5 to 15 parts of polyethylene naphthalate, 1 to 6 parts of calcium stearate, 5 to 20 parts of isocyanate coupling agents, and 1 to 2 parts of 2,6-tert-butyl-4-methylphenol. The inventor performs a great amount of selection experiments for components and usage amounts of the components, and accidentally finds that the high-strength polyphenylene sulfide is high in flexibility, low in shrinkage rate of materials, and also high in mechanical performance of a product. The prepared high-strength polyphenylene sulfide composition has prominent advantages of flame resistance, environmental friendliness, heat stability, good mechanical performance, easiness in machining and molding and the like, and is wide in application fields such as electrical field, electronic parts, automobile parts and the like.

Description

technical field [0001] The invention belongs to the technical field of new materials and environmental protection and energy saving, and in particular relates to a high-strength polyphenylene sulfide composition. 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 the phenylthio group on the main chain of its molecule, the sulfur atom and the benzene ring are neatly arranged alternately, which endows the molecule with highly stable chemical bond characteristics, and is easy to stack into a crystal lattice structure with high thermal stability, making it have many unique properties. The performance is mainly manifested in: excellent thermal stability, chemical stability, dimensional stability, corrosion resistance and electrical properties, excellent phys...
