Abstract

The invention provides an environment-friendly high-performance epichlorohydrin rubber with good processability, and its components include 30-50 parts of copolymerization type epichloride rubber and 50-70 parts of homopolymerization type epichloride rubber. This product solves the problem of nickel, lead, ethylene thiourea and other harmful substances contained in the traditional epichlorohydrin rubber formula. The present invention improves the vulcanization speed and prolongs the storage time of the rubber material through the combined use of the vulcanization system, overcomes the shortcomings of short scorch time and unstable product quality of the triazine vulcanization system of chloroether rubber, and provides a product with good processing performance and durability. Green and environment-friendly epichlorohydrin rubber with better high temperature performance. The epichlorohydrin rubber provided by the invention meets the standard of the epichlorohydrin rubber for fuel pipes.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-performance environment-friendly epichlorohydrin rubber with good processability. Background technique [0002] Chlorine ether rubber has better bending resistance and elasticity; the chlorine atoms of the side groups provide oil resistance, solvent resistance, combustion resistance, low air permeability and good adhesion; it is widely used in the manufacture of tires, hoses, tapes, Cables and other various rubber products. However, the traditional vulcanization and anti-aging systems of epichlorohydrin rubber are not environmentally friendly and have great harm to the human body and the environment. [0003] After research on the formulation of chloroether rubber, triazine-based environment-friendly vulcanization systems have been gradually applied and promoted. Chinese patent application No. 200810010681.4 discloses a TCY (2,4,6-trithiol-thiotriazine) as Vulcanizing age...
