Abstract

The invention discloses a high-efficiency solidified water-resistant adhesive. The high-efficiency solidified water-resistant adhesive comprises the following components in parts by weight: 150-270 parts of a hydrogenation bisphenol type A epoxy resin base-material, 20-45 pars of a cyanoethylated diethylenediamine curing agent, 6-12 parts of ethylene glycol diglycidylether, 15-30 parts of a filling material, 9-15 parts of an acrylic acid ester rubber, and 7-20 parts of dimethyl methylphosphate. By reasonable control of ratio between the reactants, the reaction condition can be controlled in a reasonable mode, and the epoxy resin adhesive with high endurance is prepared. The epoxy resin adhesive has the excellent moisture resistance and heat resistance, excellent machinery characteristics such as impact resistance, and has good bonding performance and, endurance performance, and a preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of polymer gels, in particular to an efficient curing water-resistant adhesive. Background technique [0002] As a commonly used bonding product in the construction industry, building adhesives are widely used in construction and interior decoration of houses. For interior decoration of houses, floor adhesives are often used in composite floors. The commonly used floor adhesives usually contain organic poisons such as aldehydes, and their release will affect human health. Therefore, it is an urgent technical problem to solve the problem of how to solve the pollution gas released by the glue used for composite floor. [0003] As an environmentally friendly gel material, epoxy resin adhesive can solve the problem of existing construction adhesives. The epoxy resin adhesive is a kind of epoxy resin binder, curing agent, diluent, accelerator and Engineered adhesives formulated with fillers. Due to its good bonding perf...
