Problems solved by technology

At present, the acrylic adhesive used in the manufacturing process of engineering-grade reflective film can only be used for pasting on the surface of metal materials such as aluminum plates due to its weak adhesion to the surface of plastic materials with low surface energy.
The scope of application of engineering-grade reflective film has been severely limited

Abstract

The invention provides an acrylate adhesive, a preparation method thereof and an adhesive for an engineering-level reflective film and belongs to the technical field of adhesives. The acrylate adhesive is prepared from the following ingredients in parts by weight: 17.6-38 parts of butyl acrylate, 0.3-1.2 parts of acrylic acid, 0-0.7 part of hydroxyethyl acrylate, 20-40 parts of methyl isobutyl ketone, 20-45 parts of ethyl acetate, 0.04-0.13 part of azodiisobutyronitrile and 8-17 parts of tackifying resin. According to the acrylate adhesive, the preparation method thereof and the adhesive for the engineering-level reflective film, the adhesive has unchanged adhesion with an aluminum coating in an engineering-level reflective film production process, so that the produced engineering-level reflective film not only has excellent surface adhesion with metallic materials such as aluminum plates, but also has good adhesion performance and outstanding water resistance when the engineering-level reflective film is stuck to surfaces of low-surface-energy materials such as PP and PE.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to acrylate adhesives, a preparation method thereof, and adhesives for engineering grade reflective films. Background technique [0002] Engineering-grade reflective film is a kind of traffic sign material with retroreflective properties. When the light shines on the engineering-grade reflective film, the light can be retroreflected. Using the performance of engineering-grade reflective film, people use it to make traffic signs and are widely used On highways and ordinary roads, especially for driving at night, it provides a good safety guarantee. At present, the acrylic adhesive used in the manufacturing process of engineering-grade reflective film can only be used for pasting on the surface of metal materials such as aluminum plates because of its weak adhesion to the surface of plastic materials with low surface energy. The scope of application of engineering-grade reflective ...
