Embodiment Construction
[0050] Below by embodiment the present invention will be further described:
[0051] Table 1 The raw material composition mass percentage of silicone emulsion in the embodiment
[0052]
[0053] Preparation:
[0054] According to the ratio of raw materials in Table 1, firstly add stabilizer and surfactant into water, mix well to obtain solution A; then add polysiloxane, nano silicon dioxide, penetration enhancer to alkoxysilane, mix well Obtain B solution;
[0055] Under high-speed dispersion conditions, add solution A dropwise into solution B; maintain high-speed dispersion during the dropping process. During high-speed dispersion, the dispersion speed of solution A is 2000rpm, and the dropping speed of solution A is 5-15g / min·kg. After completion, a white milky liquid with stable performance is formed, which is the stock solution of penetrating silicone protective agent.
[0056] Brush the above emulsion on the surface of fly ash masonry, 95 blue bricks and C30 concret...
