Problems solved by technology

For electronic products or other products, once the adhesive tape is used, it is required that the adhesive tape can maintain its viscosity under the condition of large temperature difference, and the adhesive can be easily peeled off from the film. Under other properties such as uniformity, there is a bottleneck in improving the roughness of the matte surface

Abstract

The invention discloses a matte acrylic acid adhesive. The matte acrylic acid adhesive comprises, by weight, 70-80 parts of methyl methacrylate, 25-38 parts of ethyl acrylate, 15-18 parts of dimethyldiethoxylsilane, 35-45 parts of a solvent, 2-3 parts of nano-SiO2 powder, 1.2-1.8 parts of nano-Al2O3 powder, 0.2-0.5 parts of micron-sized SiO2 powder, 0.2-0.5 parts of micron-sized Al2O3 powder, 0.6-1 part of isocyanate, 4-6 parts of rosin resin, 3-6 parts of terpene resin, 1-1.5 parts of an azo-compound, 4-6 parts of a N-nitroso compound and 0.5-2 parts of a coupling agent. The coupling agent has a chemical formula of CH2=CH-Si(OC2H5)3. The matte acrylic acid adhesive improves acrylic acid adhesive roughness under the condition of no increasing of particle diameter, prevents cluster and settlement of SiO2 and Al2O3 powder in a system and improves adhesion with a base.

Description

technical field [0001] The invention relates to an acrylic adhesive, in particular to a matte acrylic adhesive. Background technique [0002] Acrylic adhesives are used to attach one object to another. People pay more attention to the visual requirements such as the style and color of various furniture or electronic products, so the appearance of electronic products is particularly important, and the requirements for adhesive tape are getting higher and higher, often requiring strong adhesion and thickness Thinner sticky tape. For electronic products or other products, once the adhesive tape is used, it is required that the adhesive tape can maintain its stickiness and can easily peel off the adhesive from the film under the condition of large temperature difference. Under other properties such as uniformity, there is a bottleneck in improving the roughness of the matte surface. SUMMARY OF THE INVENTION [0003] The invention provides a matte acrylic adhesive, which imp...
