Abstract

The invention discloses a hybrid acrylate AB adhesive which comprises the following components in percentage by mass: a component A: 50.0%-65.0% of a polymeric monomer, 5.0%-10.0% of a functional monomer, 5.0%-10.0% of modified tackified alkyd resin, 10.0%-25.0% of reinforced resin, 10.0%-20.0% of toughened rubber, 2.0%-6.0% of a reducing agent and 0.1%-2.0% of a stabilizer; and the component B comprises the following components in percentage by weight: 55.0%-65.0% of a polymeric monomer, 2.0%-8.0% of a functional monomer, 1.0%-5.0% of methacrylic acid wax, 20.0%-35.0% of reinforced resin, 5.0%-15.0% of toughened rubber, 1.0%-6.0% of an oxidant and 0.5%-5.0% of a stabilizer. The invention also discloses a preparation method of the hybrid acrylate AB adhesive. Through compounding of the raw materials, the prepared hybrid acrylate AB glue has excellent adhesion to engineering plastics such as ABS, ASA and the like, has the characteristics of low odor, good curing debonding property, strong adhesive force, high toughness, fatigue resistance, creep resistance, good heat resistance, good weather resistance and wide range of bonding materials, and can meet the bonding requirements of new energy automobile body materials.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a hybrid acrylate AB adhesive and a preparation method thereof. Background technique [0002] In recent years, energy problems and environmental pollution problems have become increasingly serious, and the development of new energy vehicles has become an important strategy to implement the national requirements for energy conservation and emission reduction, and the development of a low-carbon economy. Different from traditional automobiles, new energy automobile body materials are more inclined to lightweight materials, such as high-strength steel, aluminum alloy, magnesium alloy, carbon fiber and various engineering plastics. At present, the traditional acrylate AB glue on the market has the characteristics of easy operation, fast curing at room temperature and high bonding strength, but it also has poor toughness, fatigue resistance and creep resistance, and is not suitable ...
