Abstract

The invention discloses an adhesive for bonding stainless steel and rubber. The adhesive comprises, by mass, 240 to 255 parts of vinyl acetate, 118 to 142 parts of butyl acrylate, 72 to 84 parts of hydroxyethyl methacrylate, 16 to 22 parts of tert-butyl acrylate, 13 to 18 parts of vinyl versatate, 2 to 5 parts of acrylic acid, 0.8 to 1.2 parts of an initiator, 30 to 34 parts of an emulsifier and 490 to 510 parts of water. The adhesive is an aqueous adhesive, does not contain nitroso-compounds and heavy metals, is environmentally friendly, does not produce any damage to the human body, can be used between stainless steel and rubber and has high bond strength.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive used for bonding stainless steel and rubber. Background technique [0002] Stainless steel and rubber are bonded into a whole through adhesives, which are involved in many fields and occupy a very important position in the industry. For example: on the engine parts of automobiles and aircrafts, the adhesives of stainless steel and rubber in the foreskins of oil seals, tires, rubber rollers, rubber linings, conveyor belts, wires and wrenches are widely used. [0003] Most of the existing adhesives used for bonding stainless steel and rubber contain nitroso compounds or lead salts, which are relatively harmful to the environment and cause great harm to the human body. For example, the patent CN93114420.5 single-coat rubber-metal adhesive contains aromatic nitroso compounds and metal compounds. And with the development of society, the bonding strength of the adhesive...
