Abstract

The invention discloses a preparation method of a water-resistant adhesive used for bonding a metal member. The method comprises the following steps: 1) preparing a raw material of hydrogenated bisphenol type A epoxy resin, then preparing the hydrogenated bisphenol type A epoxy resin for standby; 2) performing modification on the hydrogenated bisphenol type A epoxy resin, adding a modifier and performing a heating reaction with the hydrogenated bisphenol type A epoxy resin to obtain the modified epoxy resin; 3) preparing a mixed curing agent, wherein the mixed curing agent comprises 25-58 parts of a diaminodiphenyl-methane curing agent, 6-15 parts of epoxypropane o-tolyl ether, 13-25 parts of a filling material, 9-17 parts of an ethylene propylene rubber, and 6-12 parts of a DOPO fire retardant; and 4) independently packaging the modified epoxy resin and the mixed curing agent, and packaging the every two materials. Through reasonable control the ratio between the reactants, the reaction condition can be controlled in a reasonable mode, and the epoxy resin adhesive with high endurance is prepared.

Description

technical field [0001] The invention relates to the field of polymer gels, in particular to a method for preparing a water-resistant glue used for bonding metal components. Background technique [0002] As a commonly used bonding product in the construction industry, metal component adhesives are widely used in building construction and house interior decoration. For house interior decoration, metal component adhesives are often used in metal products. However, the commonly used metal component adhesives usually contain organic poisons such as aldehydes, and their release will affect human health. Therefore, how to solve the problem of releasing polluting gas from metal components with glue is an urgent technical problem. [0003] And epoxy resin adhesive can solve the problem of existing building adhesive as a kind of environment-friendly gel material, and described epoxy resin adhesive is a class by epoxy resin base material, curing agent, diluent, accelerator and Engine...
