Problems solved by technology

With the widespread use of UV-curable adhesives, the problems caused by UV-curable adhesives have become increasingly prominent. Due to their special chemical structures and characteristics, traditional UV-curable adhesives cannot be degraded or hydrolyzed by microorganisms in the environment. Long-term stay in the environment has become a major hidden danger and threat in modern society

Abstract

The invention relates to a UV curing adhesive and a preparation method thereof. The preparation method of the UV curing adhesive comprises the following steps: adding 30-60 parts of poly(butylene succinate) modified acrylate resin, 15-50 parts of a filler, 15-40 parts of an active monomer and 1-10 parts of a photoinitiator into a stirring pot and carrying out rapid stirred for 20-50 min; and then adding 0.5-5 parts of a flatting agent, and continuing stirring for 5-20 minutes. The UV adhesive provided by the invention can be naturally degraded under certain conditions after being cured, and is green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of chemical adhesives, in particular to a UV curing adhesive and a preparation method thereof. Background technique [0002] UV curing adhesive is a kind of adhesive that makes the bonded substrate quickly produce bonding performance under the action of ultraviolet light energy. UV curing adhesives have developed rapidly at home and abroad due to their advantages of fast curing speed, low curing temperature, no pollution, and energy saving. They have been widely used in printed circuit board manufacturing, optical fiber bonding, liquid crystal display installation, electronic component assembly, etc. It plays a huge role in many fields, especially in some places where traditional adhesives cannot be used, such as high-precision electronic equipment or the bonding of heat-sensitive substrates. With the widespread use of UV-curable adhesives, the problems caused by UV-curable adhesives have become increasingl...
