Abstract

The invention belongs to the technical field of rubber hoses, and particularly relates to a power steering high-pressure hose, which comprises an inner rubber layer, an enhancement layer, a middle rubber layer, an enhancement layer and an outer rubber layer which are arranged from inside to outside, wherein the inner rubber layer comprises the following components in parts by mass: 50-100 parts of chlorosulfonated polyethylene, 2-10 parts of active magnesium oxide, 1-6 parts of pentaerythritol, 1-4 parts of anti-aging agent, 2-8 parts of dispersing agent, 80-130 parts of semi-reinforcing carbon black, 10-50 parts of activated light calcium carbonate, 20-50 parts of plasticizer, 0.2-1 part of accelerant, and 0.5-5 parts of cross-linking agent; the cohesiveness of yarns and rubber is good, and through tests, the yarns and the rubber cannot be separated and can be integrally torn when being forcedly separated; the inner rubber layer is excellent in physicochemical property, the enhancement layers select rayon, hose expansion capacity is ultra low, the inside volume expansion is as low as 1.13ml / m, adhesive force inner rubber, middle rubber and outer rubber tear is realized, and the pulse performance is good.

Description

technical field [0001] The invention belongs to the technical field of rubber hoses, and in particular relates to a high-adhesion, high-pulse and low-expansion power steering high-pressure hose. Background technique [0002] Automobile steering system is very important to the driving safety of automobiles, and it is a system that must be paid attention to in automobile safety. With the development of the automobile industry and the enhancement of environmental protection and safety awareness, automobile manufacturers have put forward higher requirements for the noise and sensitivity of the power steering system. The performance is difficult to meet the needs of the market, and the requirements of low noise and high sensitivity make the ultra-low expansion power steering high-pressure hose ready to come out. [0003] Chinese patent 201010610351.6 discloses a power steering high-pressure hose, which includes five layers from inside to outside, namely inner rubber layer, braid...
