concrete sealant

Abstract

The invention provides a concrete sealing curing agent. The concrete sealing curing agent is prepared from a component A and a component B, which are packaged independently, wherein the component A is prepared from the following components in percentage by weight: 20 weight percent to 25 weight percent of sodium silicate, 5 weight percent to 15 weight percent of poly-lithium silicate, 5 weight percent to 15 weight percent of silica sol, 3 weight percent to 7 weight percent of a photocatalyst, 0.5 weight percent to 1 weight percent of a penetrating agent, 0.5 weight percent to 1 weight percent of a surfactant, 0.4 weight percent to 0.6 weight percent of a surface modifier, 0.4 weight percent to 0.6 weight percent of a de-foaming agent and the balance of de-ionized water; the component B is prepared from the following components in percentage by weight: 0.2 weight percent to 0.6 weight percent of graphene, 25 weight percent to 45 weight percent of organic silicon modified water-based epoxy resin, 5 weight percent to 15 weight percent of silica sol, 0.1 weight percent to 2 weight percent of a catalyst, 0.1 weight percent to 3 weight percent of a stabilizer and the balance of de-ionized water. The concrete sealing curing agent provided by the invention has the advantages of reasonable design, high rigidity, high permeability, good wearing resistance and good waterproof performance, and also has a protection effect on concrete.

Description

technical field [0001] The invention belongs to the technical field of protective treatment of concrete materials, and in particular relates to a concrete sealing and curing agent. Background technique [0002] Concrete refers to a mixture made of cement, granular aggregate, water, chemical admixtures and mineral admixtures that need to be added in an appropriate proportion. It has the advantages of economy, durability, fire resistance, and high compression resistance. It is one of the most important civil engineering materials in contemporary times. [0003] 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. The accelerated deterior...

AI Technical Summary

Problems solved by technology

Concrete sealing and curing agent is a multi-component chemical reagent with low viscosity. After being coated on the surface of the concrete structure, it can quickly penetrate into the interior of the concrete structure due to capillary action and react with the free calcium inside to form an insoluble amorphous state. Calcium silicate hydrate can block the pores of concrete structures and improve their hardness and water resistance. However, the existing concrete sealing and curing agents are not ideal for improving the water resistance of concrete structures.
