Concrete waterproof compacting agent as well as preparation method and application thereof
The invention discloses a concrete waterproof compacting agent as well as a preparation method and application thereof. The concrete waterproof compacting agent is prepared from 30 to 50 parts of polytetrafluoroethylene micro powder, 10 to 20 parts of nano aluminum oxide, 30 to 50 parts of sodium methyl silicate, 20 to 30 parts of sodium fluosilicate, 10 to 20 parts of trifluoropropyl methyl polysiloxane, 5 to 10 parts of polyoxyethylene fatty alcohol ether, 3 to 5 parts of silane coupling agent, 3 to 5 parts of titanate coupling agent and 800 to 1200 parts of water. The concrete waterproof compacting agent prepared by the invention contains polytetrafluoroethylene and nano aluminum oxide components, is good in aging resistance and excellent in crack resistance and water resistance, can be directly added into a concrete material, and is simple to construct; the water-proofing agent can be directly added into concrete, solves the problem that a conventional water-proofing agent cannot permeate to a sufficient depth during construction, can coat and repair the concrete on the surface, further strengthens the water-proofing and crack-resisting effects and prolongs the service life, and particularly has important significance on water proofing of underground engineering concrete.
本发明公开了一种混凝土防水密实剂及其制备方法和应用，混凝土防水密实剂包括聚四氟乙烯微粉30~50份，纳米氧化铝10~20份，甲基硅酸钠30~50份，氟硅酸钠20~30份，三氟丙基甲基聚硅氧烷10~20份，聚氧乙烯脂肪醇醚5~10份，硅烷偶联剂3~5份，钛酸酯偶联剂3~5份，水800~1200份。本发明制备的混凝土防水密实剂含有聚四氟乙烯和纳米氧化铝成分，耐老化性能好，且具有优异的抗裂防水性能，且能够直接添加在混凝土材料中，施工简单；可直接添加在混凝土中，解决了常规防水剂施工时不能渗透至足够深度的问题，且能够在表面对混凝土进行涂覆和修护，进一步强化防水、抗裂效果，延长使用年限，尤其对于地下工程混凝土的防水具有重要意义。
