Abstract

The invention provides a polyacrylate UV adhesive. The polyacrylate UV adhesive is prepared from, by weight, 50-72 parts of polyacrylate, 10-15 parts of reactive diluents, 2-7 parts of photoinitiator, 1-2 parts of stabilizer, 2-4 parts of adhesive force enhancer, 1-2 parts of pigment, 2-3 parts of thixotropic agent, 1-2 parts of flatting agent, 1-3 parts of age resister, 5-8 parts of PTFE and 2-5 parts of chromic oxide. The invention further provides a preparation method of the polyacrylate UV adhesive. The polyacrylate UV adhesive has good wear resistance.

Description

Technical field: [0001] The invention relates to a UV glue, in particular to a polyacrylate UV glue and a preparation method thereof. Background technique: [0002] UV glue, also known as shadowless glue, photosensitive glue, and ultraviolet light curing glue, is a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive or as a glue for paints, coatings, inks, etc. Material use. UV is the abbreviation of UltravioletRays in English, that is, ultraviolet light. Ultraviolet rays are invisible to the naked eye and are a section of electromagnetic radiation other than visible light. The wavelength range is generally 110-400nm. The principle of UV glue curing is that the photoinitiator (or photosensitizer) in the UV curing material absorbs ultraviolet light under the irradiation of ultraviolet light to generate active free radicals or cations, triggering monomer polymerization and crosslinking chemical reactions, so that the adhesive Converts from...
