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