Chloroprene rubber adhesive

Abstract

The invention discloses a chloroprene rubber adhesive which consists of the following components in parts by weight: 30-40 parts of chloroprene rubber, 120-150 parts of methylbenzene, 25-30 parts of tert-butyl phenol-formaldehyde resin, 2-4 parts of zinc oxide, 1-2 parts of magnesium oxide, and 0.1-0.3 part of 2,6-butylated hydroxytoluene. Compared with the prior art, the chloroprene rubber adhesive provided by the invention is high in adhesion strength, excellent in heat resistance and weathering resistance, and suitable for electronic elements easy to generate heat.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and more specifically relates to a neoprene adhesive. Background technique [0002] The rapid development of the electronic information industry provides a good environment for the rapid development of the electronic component industry. Electronic component products are characterized by small size, light weight and high performance. Bonding technology is widely used in the assembly of such products. Although neoprene adhesives have poor electrical insulation due to the polar chlorine atoms contained in their molecules, they have fast crystallization speed, high cohesion, strong initial adhesion, high bonding strength, relatively low price, and the film is elastic. And softness is good. [0003] As a solvent-based adhesive, neoprene adhesives inevitably have solvent volatilization during use, which has an impact on the environment; in addition, electronic components are prone to heat, and the c...
