Abstract

The invention discloses a power-assisted steering rubber hose made of chlorinated polyethylene rubber and a preparation method. The power-assisted steering rubber hose adopts chlorinated polyethyleneas a raw material so as to be favorable in extrusion property and capable of meeting the requirements on materials and performances of the power-assisted steering rubber hose, adopts a novel thiadiazole vulcanization system matched with an amine accelerant so as to be good in vulcanization effect, can get the best material performance through being used by an automobile, and has heat resistance and DEXRON transmission fluid resistance being approximately equal to a traditional chlorosulfonated polyethylene formula; an chlorinated polyethylene extrusion process is stable to operate, so that therequirement of the power-assisted steering hose of the automobile on the DEXRON transmission fluid resistance can be better met.

Description

technical field [0001] The invention belongs to the technical field of automobile rubber hoses, in particular to a power steering rubber hose of chlorinated polyethylene rubber and a preparation method thereof. technical background [0002] Automotive power steering hose is composed of fabric reinforcement layer and synthetic rubber. It is a hydraulic steering equipment used for the active connection between power steering device and power steering pump. The material of the hose is chlorosulfonated polyethylene rubber with a layer of fabric reinforcement in the middle. The inner layer of the hose should be resistant to damage from DEXRON transmission fluid or hydraulic power fluid specified by the buyer. Recently, due to environmental pollution and other factors, DuPont in the United States has to shut down its factories producing chlorosulfonated polyethylene materials, resulting in a shortage of chlorosulfonated polyethylene materials and a skyrocketing price. Therefore, ...
