Problems solved by technology

The design of urethane acrylate is relatively flexible, and various products with good toughness and high strength can be designed. However, in the field of adhesives, the adhesion of this kind of resin to plastics is not ideal. In addition, the selection technology of special additives in the synthesis process can achieve Colorless or yellowish transparent polyurethane acrylate resin is still difficult

Abstract

The invention relates to a polyurethane acrylate resin used for bonding PC plastic, and a preparation method thereof. each 100 weight amount of a reaction composition mainly comprises, by weight, a component A composed of 5 to 50 parts of a non-reaction type single-functionality (methyl) acrylate monomer as a diluent, a component B composed of 20 to 60 parts of one or a plurality of aliphatic polycarbonate dihydric alcohols, a component C composed of 10 to 40 parts of a bifunctionality isocyanate, a component D composed of 0.05 to 2.0 parts of two or more anti-oxidants, a component E composedof 1.0 to 25.0 parts of two or more hydroxy containing single-functionality (methyl) acrylate monomers, and a component F composed of 0.05 to 1.0 part of a condensation catalyst. The NCO / OH molar ratio of the polyurethane acrylate resin is maintained to be 1.2 to 2.5; when NCO is terminated with the hydroxy containing single-functionality (methyl) acrylate monomer, the OH / NCO molar ratio is maintained to be 1.05 to 2.0.

Description

technical field [0001] The invention relates to the technical field of photocurable oligomers, in particular to a polyurethane acrylate resin used for bonding PC plastics and a preparation method thereof. Background technique [0002] Ultraviolet curing technology does not require heating during curing, and has the characteristics of less environmental pollution, low energy consumption, high efficiency, small shrinkage, good chemical stability, and good applicability. Therefore, it is widely used in wood, glass and jewelry industry, glass furniture, medical treatment, electronics, electrical appliances, optoelectronics, optical instruments, automobile manufacturing and other fields. The main components in UV curing technology generally include oligomers, reactive diluents and photoinitiators, among which the performance of oligomers determines the basic performance of the main formulation, which occupies a considerable proportion of the entire system as a skeleton resin. It...
