Abstract

The invention discloses an automobile power steering rubber hose material. The automobile power steering rubber hose material is prepared from following raw materials, by weight, 97 to 100 parts of EPDM 4770R, 3 to 4 parts of maleic acid di-n-butyl ester, 1 to 2 parts of hexafluoro- acetylacetone, 1 to 2 parts of ethyl naphthol, 0.9 to 1 part of bis(P,P-bis-ethylhexyl diphosphato)ethanediolato titanate, 5 to 7 parts of di-n-octyl phthalate, 2 to 3 parts of polyacrylamide, 7 to 10 parts of hydrotalcite, 3 to 4 parts of glass powder, 1 to 2 parts of 1,2-dimethylimidazole, 0.7 to 1.1 parts of sulphur, 0.7 to 1 part of promoter ZBX, and 17 to 25 parts of a composite filling material. The automobile power steering rubber hose material possesses excellent rebound resilience, and using effects; is long in service life; and is capable of realizing steering preferably.

Description

[0001] technical field [0002] The invention mainly relates to the field of auto parts, in particular to an automobile steering power rubber hose material. Background technique [0003] The mechanical steering device of the car can realize the steering of the car, but when the load on the steering shaft is large, it is difficult to turn smoothly only by the driver's physical strength as the steering energy. In order to reduce the force of the driver operating the steering wheel, people add a set of power steering assist device on the basis of the mechanical steering device, and the rubber hose in this device needs to have good resilience and strong pressure resistance. Guarantee the normal use of the device. Contents of the invention [0004] The object of the present invention is to provide a rubber hose material for automobile steering power. [0005] The present invention is achieved through the following technical solutions: [0006] An automobile steering power r...
