Abstract

The invention discloses an air-brake hose material which comprises the following raw materials in parts by weight: 93-100 parts of ethylene-propylene-diene monomer rubber 4770R, 7-10 parts of polydicyclopentadiene, 4-5 parts of polyvinylidene fluoride, 2-3 parts of polyvinyl alcohol, 1-2 parts of fenbendazole, 4-6 parts of poly(butyl acrylate), 2-3 parts of monopotassium phosphate, 0.2-0.4 part of trimethylhexamethylenediamine, 2-4 parts of calcium aluminate, 4-7 parts of carbon fiber, 20-24 parts of carbon black, 1-1.6 parts of 2,4-dichlorobenzoyl peroxide, 0.8-1 part of an accelerating agent CSB, 0.4-1 part of an accelerating agent CPB and 16-27 parts of a composite filler. An air-brake hose provided by the invention is good in positioning performance, high in overall strength and good in aging resistance and corrosion resistance.

Description

[0001] technical field [0002] The invention mainly relates to the field of auto parts, in particular to a pneumatic brake 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 pneumatic brake hose material. [0005] The present invention is achieved through the following technical solutions: [0006] A pneumatic brake hose material, which is composed of the following r...
