Abstract

The invention discloses high-strength impact-resistance acrylate adhesive and a preparation method thereof. The high-strength impact-resistance acrylate adhesive is prepared from raw materials of methyl methacrylate, tetrahydrofuran metacrylic acid ester, polyoxytertramethylene glycol, diphenyl-methane-diisocyanate, cumene hydroperoxide, 2,6-di-tert-butyl-p-cresol, tetramethylthiourea, butadiene-acrylonitrile rubber, diethylaminoethanol, isophorone diamine, di-n-octyl phthalate, hydrogenated rosin resin, ethylene vinyl-acetate copolymer, lead sulfate tribasic, polyacrylic acid, nano-calcium titanate and the like. According to the high-strength impact-resistance acrylate adhesive and the preparation method thereof, provided by the invention, a flexibilizer, namely the butadiene-acrylonitrile rubber and chlorinated polyethylene are modified, so that the impact resistance and fatigue resistance of an adhesive layer are greatly strengthened, filler such as fumed silica is added so as to reduce the shrinking percentage of a curing process and improve impact-resistant toughness and other mechanical strength of the adhesive layer, and can form a hydrogen bond chain-bridged effect by being dispersed into the adhesive to generate a reversible three-dimensional network structure, so that the adhesive is endowed with the optimum flowing deformation effect.

Description

technical field [0001] The invention relates to an adhesive, in particular to a high-strength impact-resistant acrylic adhesive and a preparation method thereof. Background technique [0002] Humans have a very long history of using adhesives. As early as 5,000 years ago, people mixed water and clay as adhesives. Early human adhesives were all made of natural products, and most of them were water-soluble. At the beginning of the 20th century, with the rapid development of industrial technology, the emergence of polymer materials provided abundant raw materials for the development of adhesives, and people produced synthetic adhesives suitable for industry to replace the original natural adhesives. With the emergence of synthetic adhesives, bonding technology has made great progress, so adhesives have not been widely used as a connecting medium between materials until modern times. [0003] Acrylate adhesive is a two-component room temperature curing adhesive based on free r...
