Preparation method for water-soluble concrete silane emulsion water-proofing agent
The invention relates to a preparation method for a concrete silane emulsion water-proofing agent, in particular to a preparation method for a water-soluble concrete silane emulsion water-proofing agent and aims to solve the technical problems that silane emulsion is hard to prepare and poor in stability. The preparation method comprises the steps that 1, compound emulsifier is added to distilled water till the compound emulsifier is completely dissolved in the water, amino silicon oil is added, then triethylamine is added, triethoxyoctylsilane is added for flow returning, acrylic acid synthetic resin emulsion is added, reacting and cooling are carried out, and white emulsion is obtained; 2, phosphoric acid is added to the emulsion obtained in the step 1, the pH value of a system is adjusted to 6-10, the system is placed in a high-speed emulsifying machine to be emulsified, stabilizer polyethylene glycol 6000 and bactericide are added to the system, emulsification continues to be carried out through the high-speed emulsifying machine, and the water-soluble concrete silane emulsion water-proofing agent is obtained. The problem that silane emulsion is unstable and is prone to layering is solved, and hydrophobicity is further improved. The preparation method is applied to the field of preparation of water-proofing agents.
