Abstract

The invention relates to waterborne environment-friendly high-adhesion sealing adhesive, prepared by combining sealing adhesive stock solution, Tacolyn 3509 emulsion tackifying resin, waterborne rosin, organic wax and deionized water according to a weight ratio of 5:3:1:0.5:0.5, wherein the sealing adhesive stock solution is made by polymerizing, at a weight ratio, deionized water, an emulsifier, styrene, methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, acrylic acid, ethyl acrylate, N-methylolacrylamide, diacetoneacrylamide, a molecular control agent, a PH buffer agent, an initiator, a PH regulator and a functional aid. The invention also relates to a preparation method of the waterborne environment-friendly high-adhesion sealing adhesive. Compared with the prior art, the waterborne environment-friendly high-adhesion sealing adhesive has high initial adhesion and high permeability, can dry fast from surface in 20 s, and has peel strength of greater than 2 N / cm when it is dry.

Description

technical field [0001] The invention relates to the technical field of sealing glue, in particular to a water-based environment-friendly high-adhesion sealing glue and a preparation method thereof. Background technique [0002] Sealing glue is a one-component quick-drying water-based adhesive, non-toxic and non-polluting. Its products include hand glue and machine glue. Glue for lap molding.
