RUBBER COMPOSITION FOR HIGH-PRESSURE HOSE WITH EXCELLENT OIL RESISTANCE, WEATHER RESISTANCE, ABRASION RESISTANCE, AND ADHESION WITH BRASS-COATED STEEL WIRE

摘要

PURPOSE: A rubber composition for high-pressure hose is provided to form a rubber layer adhered with a brass-coated steel wire used in a reinforcing layer of a high-pressure hose while not using expensive rubber such as chloroprene.;CONSTITUTION: A rubber composition for high-pressure hose comprises NBR 100.0 parts by weight, PVC 10~50 parts by weight, and epoxy resin 1~15 parts by weight as an adhesive-imparting agent. The epoxy resin is a condensate between bisphenol A and epichlorohydron. The high-pressure hose comprises an inner layer(1), a reinforcing layer(2) formed on the inner layer, and an outer layer(3) formed on the reinforcing layer. The reinforcing layer of the high-pressure hose comprises brass-coated steel wire.;COPYRIGHT KIPO 2010
