Addition type fluorosilicone rubber and preparation method thereof

Abstract

The invention provides an addition type fluorosilicone rubber. The preparation steps comprise: S1, reinforcing of hydrogen-terminated polyphenyl-(dimethylsiloxy) siloxane; S2, open milling of polydimethylvinylsiloxane; S3, cross-linking mixing, and S4, curing. The invention further provides a preparation method of the addition type fluorosilicone rubber. According to the invention, the preparationmethod is simple and easy to implement, free of flash, high in precision, short in production period and suitable for large-scale production; and the prepared addition type fluorosilicone rubber is completely vulcanized and has excellent basic properties and excellent mechanical properties.

Description

technical field

[0001] The invention relates to the technical field of rubber materials, in particular to an addition-type fluorosilicone rubber and a preparation method thereof. Background technique

[0002] In today's world, the field of rubber materials is booming. As one of the stars in the field of rubber materials, fluorosilicone rubber is promoting the development of the field of rubber materials with its unique charm. This rubber material not only has the superior high and low temperature resistance of traditional silicone materials (-60℃~310℃), superior physical and mechanical properties, aging resistance and self-extinguishing at high temperature, also has excellent thermal stability of traditional fluorocarbon materials, extremely superior oil resistance and solvent resistance. Addition-type fluorosilicone rubber is a typical representative of fluorosilicone rubber. It has excellent electrical insulation properties, aging resistance, good elasticity, rapid and con...
