Abstract

A purpose of the invention is to overcome the defects of the existing waterproof material technology. The invention specifically relates to a super-weather-resistant environment-friendly ultraviolet light curing pressure-sensitive adhesive for high-end waterproof materials, and a preparation method thereof, wherein the adhesive comprises, by weight, 20-45 parts of butyl acrylate, 10-50 parts of 2-ethylhexyl acrylate, 0.5-2 parts of acrylic acid, 0-2 parts of hydroxyethyl acrylate, 60-90 parts of ethyl acetate, 0.2-2 parts of benzoyl peroxide, 0.5-3 parts of dilauroyl peroxide, 10-30 parts of apetroleum resin, 0-5 parts of an antioxidant and 0.1-10 parts of a photoinitiator. The waterproof coiled material prepared by utilizing the ultraviolet light curing adhesive disclosed by the invention has advantages of excellent weather resistance, excellent heat resistance, high adhesive force and good water resistance, and substantially meets the requirement of waterproof materials on durability.

Description

technical field [0001] The utility invention relates to the technical field of pressure-sensitive adhesives, in particular to a super-weather-resistant and environment-friendly UV-curable pressure-sensitive adhesive applied to high-end waterproof materials and a preparation method thereof. Background technique [0002] In recent years, building waterproofing occupies a very important position in engineering design. It has always been the place where quality problems are most likely to occur in construction projects. Once leakage occurs, it is difficult to completely cure it; Not enough attention has been paid to construction, thinking that as long as the building looks good and the function is reasonable, it is a good building. With the growth of the economic environment, people's concept of waterproofing of buildings has gradually changed, and the concept of focusing on price economy in the past has changed to the concept of waterproof function. Also considering the quality...
