Preparation method of modified organosilicone super-hydrophobic material, preparation method of super-hydrophobic aggregate and self-adaptive cement-based material
The invention discloses a preparation method of a modified organosilicone super-hydrophobic material, a preparation method of a super-hydrophobic aggregate and a self-adaptive cement-based material. The preparation method of the modified organosilicone super-hydrophobic material provided by the invention comprises the following steps: respectively dissolving a siloxane polymer and fluorinated nano SiO2 in an organic solvent to obtain a siloxane polymer solution and a fluorinated nano SiO2 dispersion liquid, and then mixing the two solutions to obtain a mixed solution; under the intense stirring state, absolute ethyl alcohol and a curing agent are sequentially added into the mixed solution, and the modified organosilicone super-hydrophobic material is obtained. Due to the special structure, the modified organic silicon super-hydrophobic material has super-hydrophobic performance, the modified organic silicon super-hydrophobic material is uniformly stirred with cement-based aggregate, super-hydrophobic modification of the cement-based aggregate can be realized, the cement-based material is prepared from the modified cement-based aggregate, and self-adaptive regulation and control of a cement-based structure on a complex freezing and thawing environment can be realized.
本发明公开了一种改性有机硅类超疏水材料的制备方法、超疏水骨料的制备方法和自适应水泥基材料。本发明提供的改性有机硅类超疏水材料的制备方法，包括以下步骤：将硅氧烷类聚合物、氟化纳米SiO2分别溶于有机溶剂中，得到硅氧烷类聚合物溶液和氟化纳米SiO2分散液，再将两种溶液混合得到混合溶液；在强力搅拌状态下，依次向混合溶液中加入无水乙醇和固化剂，得到改性有机硅类超疏水材料。该改性有机硅类超疏水材料由于特殊的结构使其具有超疏水性能，与水泥基骨料均匀搅拌，可实现水泥基骨料的超疏水改性，利用改性后的水泥基骨料制备出水泥基材料，能够实现水泥基构筑物对冻融复杂环境的自适应调控。
