Abstract

The invention relates to an auxiliary agent for cement gypsum products. The auxiliary agent is composed of 100 parts by weight of an EVA emulsion, 0.01 to 0.1 part by weight of benzotriazole, 0.01 to 0.1 part by weight of a dispersant, 0.01 to 0.1 part by weight of a leveling agent, and 0.01 to 0.1 part by weight of a film forming auxiliary agent; the mass content of the EVA in the EVA emulsion is 10 to 50%, and the number-average molecular weight of the EVA is 1000 to 8000. In the prior art, a concrete sealing curing agent is generally adopted to treat a concrete structure, and the concrete sealing curing agent is a multi-component chemical reagent, is very low in viscosity, and is difficult to deform after coating the surface of the concrete structure, due to the capillary action, the concrete sealing curing agent can rapidly permeate into the concrete structure and react with free calcium in the concrete structure to generate insoluble amorphous hydrated calcium silicate, so that pores of the concrete structure are blocked, and the hardness and the waterproofness of the concrete structure are improved.

Description

technical field [0001] The invention relates to an additive for cement gypsum products. Background technique [0002] During the hardening process of concrete, the surface layer and the internal structure contain a large number of interpenetrating pores. As a result, during the service process of concrete structures, it is often difficult to resist the erosion of corrosive substances in the environment due to poor surface quality or insufficient compactness, resulting in the performance of concrete structures. Accelerated deterioration, reducing the durability and service life of concrete structures, aiming at the defects of concrete. [0003] Concrete sealing and curing agent is generally used in the prior art to treat concrete structures. Concrete sealing and curing agent is a multi-component chemical reagent with low viscosity. After being coated on the surface of concrete structures, it can quickly penetrate into the concrete due to capillary action. The interior of the...
