Abstract

The invention discloses an ultraviolet curing adhesive with high hydrophobicity. The ultraviolet curing adhesive consists of the following raw materials in percentage by weight: 30-60 parts of fluorine modified urethane acrylate resin, 20-40% of a silane modified acrylate monomer, 15-30% of a methacrylate monomer and 1-7% of a photoinitiator. The ultraviolet curing adhesive with high hydrophobicity, which is disclosed by the invention, is good in hydrophobicity, high in mechanical property retention rate after being soaked into water, large in contact angle with the water, excellent in cured substance property, high in adhesion reliability and wide in application range.

Description

technical field [0001] The invention belongs to the field of photocurable materials, and relates to a UV-curable adhesive with high hydrophobicity and a preparation method thereof, which are suitable for applications requiring water-resistant environments. Background technique [0002] Light-curing materials have been widely studied due to their outstanding advantages such as fast curing speed, environmental friendliness, low energy consumption, and no solvent volatilization, and they are rapidly promoted in various industries. However, UV-curable adhesives also have their own limitations. Conventional UV-curable adhesives have obvious limitations in the application of water resistance. Because the acrylate molecular chain is highly hydrophilic, the surface contact angle is low, and the water absorption rate is high. As time goes on, some molecular chains will be destroyed by water, and a large number of water molecules will enter the colloid, so that the mechanical properti...
