Pressure-sensitive adhesive with anti-dazzle function

Abstract

The invention discloses an anti-dazzle acrylic sticker which comprises a thin film substrate layer, and the lower surface of the thin film substrate layer is connected with a release film by bonding through a pressure sensitive adhesive layer; the pressure sensitive adhesive layer is composed of the following components in parts by weight: 70-80 parts of methyl methacrylate, 25-38 parts of ethyl acrylate, 15-18 parts of dimethyldiethoxysilane, 35-45 parts of solvent, 2-3 parts of nanoscale SiO2 powder, 1.2-1.8 parts of nanoscale Al2O3 powder, 0.2-0.5 parts of micron-scale SiO2 powder, 0.2-0.5 parts of micron-scale 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 azoic compound, 4-6 parts of N-nitroso compound, and 0.5-2 parts of coupling agent. According to the invention, the roughness of an acrylic adhesive is increased under the condition of not increasing the particle diameter, the sedimentation of SiO2 powder and Al2O3 powder in a system is also avoided, and a binding force with a substrate is improved.

Description

technical field [0001] The invention relates to an adhesive, in particular to a pressure-sensitive adhesive with anti-glare function. Background technique [0002] With the vigorous development of electronic technology, electronic products such as mobile phones, MP4, MP5, cameras, digital video cameras, and notebook computers are being introduced from old to new. In order to prevent the surface of the electronic product screen from being scratched or worn and affect the use effect, a screen protective film is generally pasted on the screen surface of the electronic product. The protective film generally consists of a substrate layer and an adhesive layer coated on the substrate layer. The requirements for adhesive tapes are also getting higher and higher, and adhesive tapes with strong adhesion and thinner thickness are often required. For electronic products or other products, once the adhesive tape is used, it is required that the adhesive tape can maintain its viscosity...

AI Technical Summary

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
