Preparation method for concrete silane paste impregnation waterproof agent
The invention provides a preparation method for a concrete silane paste impregnation waterproof agent, relates to a preparation method for an impregnation waterproof agent, and aims to solve the problems that the adhesion of existing liquid silane and silane emulsion is poor. The preparation method comprises the following steps: 1, weighing; 2, mixing to obtain a mixed solution; 3, performing initial reaction to obtain a reactant; 4, emulsifying to obtain the concrete silane paste impregnation waterproof agent. The preparation method has the advantages that the shortcoming of poor adhesion of liquid silane and silane emulsion is overcome, the construction is convenient, and multiple construction manners such as spraying, brushing and roll coating can be adopted for coating of vertical surfaces, so that the loss of active substances is reduced; the permeability of a pore structure of the material per se can be maintained; the waterproofness and permeability of the concrete silane paste impregnation waterproof agent are better than those of liquid silane and silane emulsion, the water absorption of a concrete structure can be reduced by 90% or above, the penetration depth of silane is increased, and silane can penetrate into the concrete surface at 3-4 mm. The method is mainly used for preparation of the concrete silane paste impregnation waterproof agent.
