Abstract

The invention discloses an ultraviolet curing transfer printing adhesive composition for a microprism reflective film as well as a preparation method and application of the ultraviolet curing transfer printing adhesive composition. The ultraviolet curing transfer printing adhesive composition comprises the following components in parts by weight: 20-70 parts of epoxy acrylic resin; 20-40 parts of bisphenol fluorenyl polyurethane acrylate; 20-60 parts of a photopolymerization monomer; 1-5 parts of a photoinitiator; and 1-3 parts of a fluorine-modified polymer or monomer. The specific bisphenol fluorenyl polyurethane acrylate and the fluorine-modified polymer or monomer are added into an epoxy acrylic resin system to improve the refractive index and the demolding effect of the ultraviolet curing transfer printing adhesive composition. The ultraviolet curing transfer printing adhesive composition can be used for structure transfer printing in a microprism reflective film, and has a good demolding effect; and the reflectivity of the prepared microprism reflective film is high.

Description

technical field [0001] The present invention relates to the technical field of UV-curable transfer adhesives, and more particularly, to a UV-curable transfer adhesive composition for microprism reflective film and its preparation method and application. Background technique [0002] UV curing transfer adhesive has the advantages of convenient use, fast curing speed, high light transmittance, convenient operation, and environmental friendliness, and has been widely used in various plastic film industries. The UV curing transfer adhesive formula generally includes: reactive diluent monomers, photoinitiators, acrylate prepolymers, additives, etc. [0003] The micro-prism reflective film is a reflective material with high reflective brightness and excellent aging resistance. It is widely used in various road traffic safety signs, traffic safety facilities and vehicle safety devices, etc., and can play an obvious safety warning role. . The micro-prism reflective film is compose...
