Abstract

The present invention relates to an environmental protection aging-resistance acrylate adhesive, which comprises two components, wherein the first component comprises, by weight, 50-70 parts of a methacrylate or acrylate combination monomer, 10-15 parts of an epoxy modified acrylate monomer, 5-8 parts of a toughening agent, 1-10 parts of a thickening agent, 1-10 parts of a peroxide, and 0.1-5 parts of a stabilizer, and the second component comprises, by weight, 45-65 parts of a methacrylate or acrylate combination monomer, 10-15 parts of an epoxy modified acrylate monomer, 5-8 parts of a toughening agent, 1-10 parts of a thickening agent, 5-15 parts of an adhesion tackifier, and 1-10 parts of an accelerant composition. Compared with the adhesive in the prior art, the adhesive of the present invention has characteristics of substantially improved production operation field environment quality, excellent peeling performance, good shear strength, good tensile strength and good weathering resistance.

Description

technical field [0001] The invention relates to an adhesive, in particular to an environment-friendly and aging-resistant acrylic adhesive. Background technique [0002] Acrylate adhesive is a kind of ester monomer containing acrylic acid or methacrylic acid structural group as the base material, which can be quickly cured by adding curing agent, initiator and accelerator, and can achieve a certain adhesiveness in a short period of time. Thermosetting structural adhesives with high bonding strength and bonding effect. The first generation of acrylate adhesive (First gener-ationaerylie adhesive, referred to as FGA) was accidentally discovered by Eastman Company of the United States when it synthesized a series of vinyl compounds in 1955. It is mainly composed of acrylic monomers, catalysts, and elastomers. Although this adhesive has high shear strength, its peel strength, bending and impact strength are low, and its curing speed is slow, so it was not widely used in the earl...
