Abstract

The invention relates to a formula of an adhesive for metal and an application of the adhesive, in particular to a formula of adhesive primer for hot vulcanization of chloroprene rubber and metal parts and belongs to the field of preparation processes of the adhesive for metal. The formula of the adhesive for metal comprises raw materials in parts by weight as follows: 100 parts of a polyisocyanate adhesive, 40-60 parts of chlorinated rubber cement containing chlorinated rubber and a solvent as well as 40-60 parts of chloroprene rubber cement containing chloroprene rubber and a solvent. The application of the adhesive for the metal comprises the steps as follows: (1) preparation of the chloroprene rubber cement; (2) preparation of the chlorinated rubber cement; (3) compounding; (4) coating; (5) vulcanization. The vulcanization bonding strength of the adhesive with metal is greatly improved, the bonding strength is about 10 MPa, and the preparation process is simple and feasible while the bonding performance is improved. The adhesive has low requirements for application environments and little use limitation.

Description

technical field [0001] The invention relates to a formula of bonding glue for metal and its application, in particular to the formula of thermally vulcanized bonding primer for neoprene rubber and metal parts, and belongs to the field of preparation technology of bonding glue for metal. Background technique [0002] Neoprene is one of the most widely used rubber materials in the field of underwater acoustic transducers. It not only has high tear strength, but also has good oil resistance, sea water resistance, low temperature resistance, and high insulation performance. At present, thermal vulcanization molding is widely used in the sound transmission seal of underwater acoustic transducers. Neoprene and metal are very different heterogeneous materials. It is directly vulcanized and bonded to the metal, and the bonding force is low. The method of thermal vulcanization bonding is often used, that is, a series of surface treatments are first performed on the metal, and then th...
