Abstract

The invention discloses a low odor acrylate adhesive for level bonding, which comprises a component A and a component B, wherein the component A comprises the following raw materials: 40-65wt% of monofunctional acrylate monomer, 1-10wt% of bifunctional acrylate monomer, 15-30wt% of shock resistance core-shell resin, 5-15wt% of elastomer, 1-5wt%of initiator, 0.1-1wt% of stabilizer, 0.1-2wt%of coupling agent and 0.3-1wt% of volatilization inhibitor; the component B comprises the following raw materials: 40-65wt% of monofunctional acrylate monomer, 1-10wt% of bifunctional acrylate monomer, 15-30wt% of shock resistance core-shell resin, 5-15wt% of elastomer, 1-3wt% of adhesion accelerator, 0.1-1wt% of reducer, 0.1-1wt% of stabilizer, 0.01-1wt% of accelerator and 0.3-3wt% of volatilization inhibitor; and the component A and the component B are uniformly mixed at a volume ratio of 1:1. The prepared acrylate structural adhesive has the characteristics of low odor, environmental friendliness,good low temperature impact resistance and the like, and higher stripping strength and shear strength for plastics and metals.

Description

technical field [0001] The invention relates to the technical field of two-component acrylic structural adhesives, in particular to a low-odor acrylic adhesive used for level bonding and a preparation method thereof. Background technique [0002] Two-component acrylate adhesives are widely used in structural bonding in various industries due to their characteristics of fast curing at room temperature, high strength, good toughness, and simple process. With the improvement of environmental protection requirements, many factory workers require the use of acrylic structural adhesives that do not contain strong pungent odors (such as methyl methacrylate). [0003] Instant adhesive has excellent fast positioning performance, but usually has poor heat resistance and moisture resistance, low peel strength and impact strength, especially in low temperature environments with almost no impact strength. [0004] Two-component epoxy adhesive has the characteristics of high temperature ...
