Abstract

The invention relates to an anti-static adhesive resin on an aluminum surface. The anti-static adhesive resin comprises the following components in parts by weight: 50 parts of ethylene-methacrylate copolymerization resin, 40-60 parts of ethylene-vinyl acetate copolymerization resin, 6-10 parts of graphite, 1-5 parts of silane coupling agent, 10-30 parts of butadiene styrene rubber and 0.1-1 part of antioxidant. The prepared adhesive resin can form good adhesion with aluminum and has good anti-static performance.

Description

[0001] technical field [0002] The invention relates to an antistatic adhesive resin on the surface of aluminum. Background technique [0003] Ordinary bonding resins are generally insulators, and their volume resistivity is greater than 10 10 Ω·cm, its conductivity can be improved by introducing conductive fillers. When the volume resistivity drops to 10 6 -10 10 When the volume resistivity is lower than Ω·cm, the bonding resin begins to have antistatic ability; as the volume resistivity further decreases, the bonding resin can even become a semiconductor and a conductor. The improvement of the conductivity has expanded the application field of the bonding resin, and it has been widely used in the fields of antistatic and electronic equipment. [0004] Aluminum and aluminum alloys are light in weight, corrosion-resistant, high in mechanical strength, and high in production efficiency. They have been widely used in various industries, especially in automobiles, motorcyc...
