A reinforced organic-inorganic composite concrete external curing agent and a preparation method thereof, wherein the external curing agent is made from the following raw materials: 15-20 parts of paraffin wax, 10-15 parts of microcrystalline wax, 5-10 parts of stearic acid parts, 10-20 parts of polymer emulsion, 5-10 parts of strengthening components, 5-10 parts of compound emulsifier, 0.2-2 parts of defoamer, 0-3 parts of leveling agent, and 50-100 parts of deionized water. The polymer emulsions are styrene-acrylic emulsion, pure acrylic emulsion, silicone-acrylic emulsion, and ethylene-propylene emulsion; the strengthening components are polyether-hydrated calcium silicate organic-inorganic composite material, triethanolamine, calcium nitrate, calcium formate, urea, silicic acid Sodium, potassium silicate, sodium metasilicate pentahydrate; compound emulsifier is polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monostearate, sorbitan monostearate, Sorbitan fatty acid ester, nonylphenol polyoxyethylene ether, etc. Also provided is a preparation method of the external curing agent. The invention can improve the effective water retention rate and compressive strength ratio of concrete. |
