Abstract

The invention provides an ultraviolet-curing pressure-sensitive composition and a pressure-sensitive adhesive. The ultraviolet-curing pressure-sensitive composition comprises low polymers, a reactive diluent and a photoinitiator, wherein the weight ratio of the reactive diluent to the low polymers is 40:60-60:40, and the weight content of the photoinitiator in the composition is 1-5%. The low polymers comprise the following components in parts by weight: 20-40 parts of polyolefin acrylate and 4-30 parts of polyurethane acrylate. The ultraviolet-curing pressure-sensitive composition can not result in pollution caused by solvent volatilization in the use process. The weight ratio of the monomer reactive diluent to the low polymers is controlled at 40:60-60:40, so that the bonding property of the pressure-sensitive adhesive is greatly enhanced. Furthermore, by using the polyolefin acrylate as the component of the low polymer, the olefin functional group can enable the pressure-sensitive adhesive formed by the ultraviolet-curing pressure-sensitive composition to have higher weather resistance and further have higher light transmission rate.

Description

technical field [0001] The invention relates to the field of adhesive materials, in particular to a UV-curable pressure-sensitive composition and a pressure-sensitive adhesive Background technique [0002] The pressure-sensitive adhesives commonly used at present are mostly manufactured by solvent-based coating method, emulsion-type coating method or hot-melt adhesive coating method. Among them, the solvent-based coating method is to dissolve the adhesive in a solvent (such as gasoline, xylene, etc.), and then apply it to the anti-adhesive material (kraft paper, polyethylene film, silicone) after dissolving, and then dry it. The treatment then transfers the adhesive to the substrate by transfer coating to form a pressure sensitive adhesive patch. Due to the thinness of the base material, it is generally coated with organic silicon and fluorine substances to reduce the adhesion of the adhesive layer to the surface of the base material. The emulsion type coating method is to...
