Fluororubber composition and molding articles

Abstract

The invention discloses a fluororubber rubber composition and moulding product, which comprises the following parts: 100wt% fluororubber, 5-50wt% non-metal whisker and 0. 1-5wt% surface activator. The invention possesses high stretching strength and modulus, which improves heat resistance and abrasion resistance.

Description

technical field [0001] The present invention relates to a fluororubber composition and its molded articles, especially a fluororubber composition and its molded articles for sealing purposes. Background technique [0002] Viton is a kind of high temperature resistant and medium resistant rubber, which is widely used in the manufacture of engine oil seals, sealants and other products. However, the conventional physical properties of fluorine rubber decay quickly under high temperature conditions, so it is necessary to improve the physical properties at room temperature as much as possible. At present, carbon black, white carbon black, etc. are commonly used as fillers, which can be used under normal circumstances, but in the case of harsher conditions, such as: separators for deep wells in oil extraction, crankshaft oil seals for automobile engines, and the current fluorine Rubber has problems such as large compression permanent deformation and short service life.
