Preparation method of organic silicon super-hydrophobic material, preparation method of super-hydrophobic coating composite material and coating type super-hydrophobic mortar
The invention discloses a preparation method of an organic silicon super-hydrophobic material, a preparation method of a super-hydrophobic coating composite material and coating type super-hydrophobic mortar. The preparation method of the organosilicone super-hydrophobic material provided by the invention comprises the following steps: respectively dissolving polydimethylsiloxane and KH570-SiO2 in butyl acetate and absolute ethyl alcohol to obtain a polydimethylsiloxane solution and a KH570-SiO2 dispersion liquid, and then mixing the two solutions to obtain a mixed solution; and mixing the mixed solution with a curing agent to prepare the organic silicon super-hydrophobic material. The high-volatility absolute ethyl alcohol is used as the dispersion liquid, gas-phase-induced phase separation is generated along with volatilization of the dispersion liquid, a large number of micropore gas cavity structures are captured in the uniform and stable low-surface-energy layer, finally, a self-assembled porous micro-framework structure is formed, mechanical robustness is provided for the coating, and the mechanical performance of the coating is improved. And the coexistence of the nano particles and the microporous air cavities ensures that the coating has super-hydrophobicity.
本发明公开了一种有机硅类超疏水材料的制备方法、超疏水涂层复合材料的制备方法和涂层式超疏水砂浆。本发明提供的有机硅类超疏水材料的制备方法，包括以下步骤：将聚二甲基硅氧烷、KH570‑SiO2分别溶于乙酸丁酯、无水乙醇中，得到聚二甲基硅氧烷溶液和KH570‑SiO2分散液，再将两种溶液混合得到混合溶液；然后将混合溶液与固化剂混合制得有机硅类超疏水材料。以上将高挥发性的无水乙醇作为分散液，随着分散液的挥发产生气相诱导的相分离，使均匀稳定的低表面能层内部捕获了大量微孔气腔结构，最终形成自组装的多孔微骨架结构，进而为涂层提供机械鲁棒性，且纳米粒子与微孔气腔的同时存在保证涂层具有超疏水性。
