Preparation method of concrete early strength agent
The invention discloses a preparation method of a concrete early strength agent. Firstly, allyl polyethylene glycol, acrylic acid, sodium methallyl sulfonate, maleic anhydride and tert-butyl peroxybenzoate are mixed, heated, kept warm and cooled to the room temperature, octadecanol, p-toluenesulfonic acid and ethyl acetate are added, heated, kept warm and cooled to the room temperature, octadecanol, p-toluenesulfonic acid and ethyl acetate are added, heated, kept warm and cooled to the room temperature, a mixture A is sequentially washed with a sulfuric acid aqueous solution with the volume percentage being 1%-3%, a NaOH aqueous solution with the volume percentage being 1%-3% and water, air-dried and then mixed with benzotriazole, 2,6-tert-butyl paracresol, hexamethylenetetramine, trimellitate, a surfactant, triisopropanolamine, sodium nitrite, sodium sulfate, calcium chloride, aluminum potassium sulfate and ethanol, the mixture is stirred, and the concrete early strength agent is obtained. The early strength agent can substantially improve the early strength and the later strength of concrete and shorten the construction period and further has excellent performance of water reduction, plasticity maintaining, rusting prevention and stability.
