专利汇可以提供Vibration insulating rubber with fittings and manufacture thereof专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent the lowering of an adhesive strength under a corrosive environment by providing a rough surface on at least the mating surface with a rubber elastic member of a fittings and a chemically formed film on the fittings face including the rough surface while an adhesive layer is provided on the mating surface of bond the rubber elastic member and the fittings integrally.
CONSTITUTION: A rugged surface is formed on a face of a fittings. Then, the fittings face including the rough surface is subjected to a chemical treatment for film forming. After a washing thereof with water, an adhesive layer with a specified thickness is formed. The fittings thus treated is arranged in a vulcanization molding die and green rubber is injected thereinto or a vulcanized rubber molded into a specified shaped is brought into contact with the fittings to heat and pressurize it. Then, the rubber and the fittings are integrated by adhesion through the adhesive layer. This can prevent corrosion to be caused by a local electric current phenomenon when water, salt water and the like permeate into the adhesion interface through the adhesion end while strengthening the bond between the rubber elastic member and the fittings combined with an effect of increased surface area of bonding due to the rough surface provided on the surface of the fittings.
