Acrylate adhesive

Abstract

The invention discloses an acrylate adhesive which is a two-component adhesive and comprises a reducing agent and an oxidizing agent, wherein the reducing agent comprises the following components in%age by weight: 30-70% of an acrylate monomer containing at least one vinyl group, 1-10% of methacrylic acid, 5-15% of an elastomer, 0-0.1% of a stabilizer, 5-20% of toughening resin, 0.1-2% of an accelerator, 0.1 to 2% of an activating accelerator, 0 to 10% of a filler, 0.5 to 3% of an adhesion promoter, 1 to 5% of tackifying resin, 0 to 2% of a surface drying promoter, 0.5 to 1.5% of a coupling agent and 0 to 2% of a thixotropic agent. The oxidizing agent comprises the following components in%age by weight: 20-40% of epoxy resin, 15-25% of a plasticizer, 10-15% of polyether polyol, 20-40% of a peroxide, 4%-6% of a thixotropic agent and 0.1%-0.3% of ferric ferrocyanide. The volume ratio of the reduce agent to the oxidizing agent is 10: 1. The acrylate adhesive has weak corrosion to copper, good bonding effect and good storage stability..

Description

technical field [0001] The invention relates to a chemical synthetic adhesive, in particular to an acrylic adhesive. Background technique [0002] Acrylic adhesives have fast curing speed, high strength, good toughness, and oily surface bonding, and are widely used in machinery, electronics, transportation, handicrafts and other fields. But because it has strong corrosivity, especially to the corrosion of copper, a kind of black substance will be formed on the surface of copper, which will have a negative impact on the conductivity of copper, although the acrylic adhesive disclosed in the prior art passes through Adding a corrosion inhibitor reduces its corrosion on the copper surface, but the bonding effect is poor and the storage stability is poor. Contents of the invention [0003] Aiming at the above-mentioned technical defects, the present invention provides a two-component acrylate adhesive with weak corrosion to copper, good bonding effect and good storage stabilit...
