Abstract

The invention discloses a preparation method for a multifunctional super-hydrophobic hybrid material (coating) which not only has the photocatalysis performance, but also has super-hydrophobic performance. The preparation method comprises the following steps: firstly, preparing stable silicon dioxide gelatin and titanium dioxide gelatin; adding the silicon dioxide gelatin and the titanium dioxide gelatin at the mass ratio of 1.0-4.0 into an organic silane alcohol solution; sealing, and standing at the temperature of 60-75 DEG C; washing for 3-5 times by an alcohol solution after 16-24 h standing; performing centrifugation, drying and crushing to obtain drainage TiO2-SiO2 mixed gelatin powder; adding the TiO2-SiO2 mixed gelatin powder into a polymer organic solvent, performing supersonic treatment for 30-60 min, quickly stirring at the room temperature for 10-30 min to obtain a mixed hybrid emulsifiable solution.

Description

technical field

[0001] The invention relates to a preparation method of a hybrid material, more specifically to a preparation method of a multifunctional superhydrophobic hybrid material. Background technique

[0002] Superhydrophobic (surface static contact angle greater than 150°) surfaces widely exist in nature. Natural selection, survival of the fittest, many characteristics of organisms in nature through evolution are almost perfect, many plant roots and leaves, insect wings, water strider legs and bird feathers are all natural super-hydrophobic materials . Studies have shown that by constructing a rough surface with low surface energy and micro-nano scale, a super-hydrophobic surface can be obtained, on which water droplets can roll back and forth freely, and remove pollutants such as dust attached to the surface, thereby effectively containing the material Surface pollution, oxidation, snow accumulation, and fluid viscosity have brought great convenience to people's...
