Abstract

The invention relates to an ultraviolet curing adhesive with high elongation and low elastic modulus and a preparation method thereof. The ultraviolet curing adhesive comprises the following raw materials by weight percent: 25-70% of polyurethane-acrylate oligomer, 20-70% of propyleneesters active diluent, 2-7% of photoinitiator and 1-5% of mercaptan compound. The preparation method of the ultraviolet curing adhesive comprises the following steps: weighting the raw materials by weight percent, adding into a stirrer, vacuumizing until the vacuum degree is -0.08MPa to -0.05Mpa, stirring uniformly at the speed of 500-1,000r / min for 0.5-2h, and airing at normal temperature to obtain the ultraviolet curing adhesive. The ultraviolet curing adhesive with high elongation and low elastic modulus overcomes the defects of low elongation and high elastic modulus of the conventional ultraviolet curing adhesive and has excellent performance, high adhesion reliability and a wide range of application.

Description

technical field [0001] The invention relates to an ultraviolet light curing adhesive, in particular to an ultraviolet light curing adhesive with high elongation and low elastic modulus and a preparation method thereof, belonging to the field of adhesives. Background technique [0002] UV-curable adhesives have been widely studied due to their outstanding advantages such as fast curing speed, environmental friendliness, low energy consumption, and no solvent volatilization, and are rapidly promoted in various industries. However, UV-curable adhesives also have their own limitations. The elongation of conventional UV-curable adhesives is not high, and they cannot be used well in some occasions that require high elongation. In addition, the elastic modulus of conventional UV-curable adhesives is relatively high, and how to reduce the elastic modulus is also an urgent problem to be solved. Contents of the invention [0003] In order to solve the problems of low elongation and...
