Problems solved by technology

The process is as follows: the free radical photoinitiator first absorbs UV light energy to be excited, and then transfers electrons to the iodonium salt, and then generates super acid to initiate cationic photopolymerization and free radical to initiate free radical photopolymerization. The inhibition of free radicals and the sensitivity of cationic polymerization to water improve the curing degree and physical and chemical properties of the coating film, and solve the problems of oxygen inhibition and slow curing caused by the single initiator. At the same time, the photocuring speed is fast and the dissolution Good performance, absorption wavelength up to 390nm, is a high-efficiency, energy-saving, environmentally friendly light-curing release coating

Abstract

The invention provides a high-efficiency anti-sticking UV release coating applied to pressure-sensitive adhesives and its preparation and application; the coating comprises the following components and weight percentages: photoinitiator 3-8%, co-initiator 3-5% %, reactive diluent 20‑40%, silicone acrylic resin 15‑45%, non-silicon type acrylic resin 25‑45%. The present invention adopts a free radical and cationic compound initiator system, and utilizes the sensitization effect obtained by the synergistic effect of the two to better solve the problems of oxygen inhibition and slow curing caused by the single initiator, and at the same time, the photocuring speed is fast , good solubility, absorption wavelength up to 390nm, is a high-efficiency, energy-saving, environmentally friendly light-curing release coating.

Description

technical field [0001] The invention relates to a high-efficiency anti-adhesive UV release coating applied to pressure-sensitive adhesives and its preparation and application. Background technique [0002] Pressure-sensitive adhesive is the abbreviation of pressure-sensitive adhesive. It is a type of adhesive that can be firmly bonded to the adherend without solvents, heat or other means, just by applying light finger pressure. Release coatings, also known as release agents and anti-sticking agents, are widely used in rolls of transparent adhesives, label pressure-sensitive adhesives, paper diapers, etc. Film, dry film photoresist (for engraving electronic circuit boards) and other fields, the main function is to protect the rubber surface of pressure-sensitive adhesive products. When the pressure-sensitive adhesive is used, the release protective film can be easily peeled off. It can be said that the coating area of ​​the pressure-sensitive adhesive is as large as the coa...
