Problems solved by technology

[0002] With the prosperity of the domestic auto market, the car film industry has gradually formed a scale. Thousands of domestic film adhesive suppliers have been unable to enter the high-end market due to technical defects.
At present, the high-performance, solvent-based special adhesive technology for automotive film is mainly monopolized by multinational giants such as Rohm and Haas and 3M. still unable to compete with the aforementioned multinational giants
[0003] The defect of most adhesive products in the market at present is that the acrylic system as the main body cannot meet the comprehensive balance of high stickiness, high peel strength and high transparency, weather resistance and heat resistance

Abstract

The invention discloses an adhesive for an automobile adhesive film and a preparation method thereof, and belongs to the field of adhesives. The adhesive consists of 25-45% of acrylate soft monomers, 5-10% of hard monomers, 3-10% of acrylic acid series functional monomers, 0.1-2.0% of solvent initiator, 40-50% of organic solvent, 0.05-0.5% of thiol chain transfer agent, 0.5-5% of silane coupling agent and the like. The adhesive is mainly used as a protective film for automobile glass, and is formed by polymerizing monomers with similar refraction coefficients. The film formed by the adhesive polymer has the advantages of favorable transparence, outstanding weatherability and high yellowing resistance, and can satisfy the demands of adhesives for the automobile adhesive film.
