Reinforced organic-inorganic composite concrete external curing agent and preparation method thereof

Abstract

The invention discloses a reinforced organic-inorganic composite concrete external curing agent and a preparation method thereof. The external curing agent is prepared from the following raw materials: 15-20 parts of paraffin, 10-15 parts of micro-crystalline wax, 5-10 parts of stearic acid, 10-20 parts of polymer emulsion, 5-10 parts of a reinforcing component, 5-10 parts of a composite emulsifier, 0.2-2 part of an anti-foaming agent, 0-3 parts of a leveling agent and 50-100 parts of deionized water. The polymer emulsion is a styrene-acrylic emulsion, a pure acrylic emulsion, a silicone acrylic emulsion or an ethylene-propylene emulsion; the reinforcing component is a polyether-hydrated calcium silicate organic inorganic composite material, triethanolamine, calcium nitrate, calcium formate, urea, sodium silicate, potassium silicate and sodium meta-silicate pentahydrate; and the composite emulsifier is polyoxyethylene sorbitan mono-oleate, polyoxyethylene sorbitan mono-stearate, sorbitan mono-stearate, sorbitan fatty acid ester, nonyl phenol polyoxyethylene ether and the like. The invention also provides a preparation method of the external curing agent. The effective water retention rate and the compressive strength ratio of concrete can be improved by the external curing agent.

Description

technical field [0001] The invention relates to a concrete external curing agent, in particular to a reinforced organic-inorganic composite concrete external curing agent, which belongs to the technical field of building material chemical additives. The invention also relates to a preparation method of the reinforced organic-inorganic composite concrete external curing agent. Background technique [0002] Cement concrete has strong bearing capacity, good durability, and surface machinability. Its raw material resources are very rich and it has a mature mixing process. It is currently the most widely used and used building material in the world. The performance of concrete is mainly determined by three factors, namely, the performance of concrete raw materials, the design of concrete mix ratio, and the post-concrete maintenance. Among them, the post-maintenance of concrete will have a decisive impact on the final performance of concrete. If the concrete maintenance is not tim...

Problems solved by technology

[0005] Some of the above technologies are relatively complicated, and some use organic fluorine monomers, which are expensive and increase the cost of curing agents; and their inorganic components such as montmorillonite and illite will be compatible with organic components after organic surface treatment. Increased resistance, but it will significantly increase the viscosity of the system, which will have adverse effects on the later packaging, transportation and construction of the product

[0006] The above technologies have not given specific guidance on how to make the external curing agent of concrete improve the effective water retention rate and compressive strength ratio of concrete
