Abstract

The invention discloses a vehicle-used oil resistant insulated rubber pipe, which comprises the following raw materials in parts by weight: 81-90 parts of ternary ethylenepropylene EP35, 25-30 parts of butyronitrile rubber, 1-2 parts of sulfosuccinate sodium salt, 4-6 parts of brucite, 2-3 parts of beta-diketone, 2-3 parts of calcium phosphate, 30-35 parts of carbon-white, 2-4 parts of hydrate zinc borate, 1-3 parts of 4,4'-oxybis benzenesulfonyl hydrazide, 2-4 parts of calcium fluoride, 2-3 parts of triglycol, 1-2 parts of an accelerant CA, 1-2 parts of an antiager KY405, 0.8-1 part of sulphur and 14-25 parts of composite filler. The vehicle-used oil resistant insulated rubber pipe, disclosed by the invention, has the characteristics of good oil and flex resistant and anti-crack performance, good utilization of electric insulation performance of carbon-white and high insulation performance, and meanwhile has excellent insulation performance and improved security.

Description

[0001] technical field [0002] The invention mainly relates to the field of auto parts, in particular to an oil-resistant insulating rubber tube for vehicles. 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 an oil-resistant insulating rubber tube for vehicles. [0005] The present invention is achieved through the following technical solutions: [0006] An oil-resistant insulating...
