Abstract

The invention discloses an adhesive used for a waterproof roll. The adhesive used for the waterproof roll takes lactic acid / glycerol organic zirconium as a crosslinking agent and an ethylene-ethyl acrylate copolymer fiber-based solution as a thickening agent, so that the adhesive used for the waterproof roll has obvious temperature-sensitive crosslinking property, and gel with good temperature and shearing sustainability can be formed under the crosslinking action; meanwhile, the copolymer base solution treated by fibers is adopted, so that surface activity of the copolymer can be improved, the crosslinking effect can be promoted, and viscoelasticity and thixotropy can be improved.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for waterproof coiled material and a preparation method thereof. Background technique [0002] Traditional vegetable adhesives are easily hydrolyzed at high temperatures and have poor protection for the substrate, while ethylene-ethyl acrylate copolymer has strong thickening ability and good temperature resistance; [0003] Usually, the most commonly used crosslinking agent for obtaining polymer gels is organoboron or organozirconium, and organoboron crosslinking agents can only withstand temperatures up to 150°C. Organic zirconium can be crosslinked under acidic conditions and has high temperature resistance. Up to 200 ° C, has broad application prospects. Contents of the invention [0004] The purpose of the present invention is to provide a kind of adhesive for waterproof coiled material and its preparation method. [0005] The present invention is achieved through the following ...
