Abstract

The invention discloses a high-speed coating super-transparent acrylate pressure-sensitive adhesive emulsion, which comprises the following raw materials in parts by weight: 60-90 parts of acrylate soft monomer, 3-25 parts of acrylate hard monomer, functional 0-10 parts of monomer, 2-10 parts of high refractive index monomer, 0-0.05 part of molecular weight regulator, 0.1-0.8 part of reactive anionic emulsifier, 0.1-0.5 part of reactive nonionic emulsifier, 0.02 part of defoamer -0.1 part, substrate wetting agent 0-0.08 part, initiator 0.2-1.0 part, water; pH value: 7.5-8, solid content: 40-55%. The pressure-sensitive adhesive emulsion of the present invention can not only be coated at high speed (150‑300m / min), has no defects such as bubbles on the rubber surface, and the peeling force is not less than 2.0N / 10mm, and the light transmittance can reach more than 90%, which can be widely used Used in the manufacture of protective films in the fields of decoration, electronics, electrical appliances and automobile industries.

Description

technical field [0001] The invention belongs to the field of pressure-sensitive adhesives, and in particular relates to a super-transparent acrylic pressure-sensitive adhesive emulsion that can be coated at a high speed and a preparation method and application thereof. Background technique [0002] The ultra-transparent acrylate pressure-sensitive adhesive that can be coated at high speed means that within the coating speed range of 150-300m / min, there is no residual adhesive on the surface of the adherend when it is peeled off from the adherend, and it maintains a certain mechanical strength. At the same time, it has high Light transmittance and low haze value. [0003] At present, the ultra-transparent acrylate pressure-sensitive adhesives that can be coated at high speed are mainly solvent-based acrylates. Solvent-type acrylate has excellent comprehensive properties, but it contains 50-70% of organic solvents such as toluene and ethyl acetate, which not only affects the ...
