Abstract

The invention relates to an automobile power-steering pipe structure and a rubber formula; the automobile power-steering pipe is that: an inner layer adopts butyronitrile inner rubber and an outer layer adopts chloroprene outer rubber; the structure is that: butyronitrile inner rubber/braided wires/butyronitrile middle rubber/braided wires/butyronitrile outer rubber; or butyronitrile inner rubber/braided wires/butyronitrile outer rubber; meanwhile, the invention provides a butyronitrile inner rubber formula and a chloroprene outer rubber formula; the conveying medium of the inner rubber layeradopts the butyronitrile rubber, as the butyronitrile rubber contains acrylonitrile and has polarity, besides the oil resistivity, the butyronitrile rubber has the characteristics of ageing resistance and low ventilation property; the outer layer adopts chloroprene rubber which has god heat resistance and ozone resistance. By adopting contrastive analysis of the butyronitrile rubber, the chloroprene rubber formula and chlorosulfonated polyethylene rubber formula, the formula performance can meet standard requirements. The automobile power-steering pipe which is prepared by the formula which replaces the chlorosulfonated polyethylene rubber formula can meet normal production conditions and performance and reduce the material cost.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to automobile power steering hose structures and rubber formulas. Background technique [0002] With the rapid development of the automobile industry, the application of power steering gears in automobile steering systems is becoming more and more common. Among them, the rubber hose must use materials with good heat resistance and power steering fluid resistance. Patent No. 200510049886.X discloses a power steering tube formula and production process, which discloses a chlorosulfonated polyethylene rubber formula. But at present, due to the closure of its chlorosulfonated polyethylene rubber production plant by DuPont of the United States, and the production capacity of other manufacturers is too small, the global supply of chlorosulfonated polyethylene rubber is tight, and the sales price of its products has also skyrocketed. It causes users who use chlorosulfonated polyethy...
