Problems solved by technology

At present, most superhydrophobic coatings use high-priced fluorine-containing low-surface-energy materials as starting materials, and are prepared in two or more steps under harsh conditions, so the practicability is greatly limited.

Embodiment Construction

[0016] The preparation method of superhydrophobic coating, comprises the following steps:

[0017] (1)D 5 / SiO 2 in situ polymerization;

[0018] (2) Surface pretreatment of glass slides;

[0019] (3) Prepare the coating by air spraying.

[0020] Among them, D 5 / SiO 2 The method of in situ polymerization is:

[0021] (1) Weigh D 5 , ethanol and nano-SiO 2 , placed in a weighing bottle, and ultrasonically oscillated for 10 minutes: add 0.06g of concentrated sulfuric acid, continue to oscillate for 15 minutes, and seal it at room temperature for 24 hours;

[0022] (2)D 5 and the quality of ethanol are constant weight 3.00g and 0.50g respectively, nano-SiO 2 The mass is 0.07g; add 0.04g KH570, ultrasonic treatment for 30min, and finally obtain a series of slight emulsions.

[0023] Wherein, the method for pretreatment of the surface of the slide glass is: clean the slide glass, and then immerse the slide glass in a mixture of ammonia water:hydrogen peroxide:water=1:1:...

Abstract

The invention relates to the field of preparation in the materials chemistry, in particular to a preparation method of a super-hydrophobic coating. The preparation method of the super-hydrophobic coating includes the steps of (1) in-situ polymerization of D5 / SiO2, (2) glass slide surface pretreatment (3) coating preparation by air spraying. In D5 / SiO2 in-situ polymerization, KH570 is used for modification, and the super-hydrophobic coating is successfully prepared on the surface of glass by means of air spraying. Infrared spectrum detection results show that nano SiO2 particles and D5 ring-opening products are compounded successfully. The preparation method is simple to operate and practical.

Description

technical field [0001] The invention relates to the field of chemical preparation of materials, in particular to a method for preparing a superhydrophobic coating. Background technique [0002] The surface of the lotus leaf is composed of a "papillary" layer and a low surface energy waxy layer. Inspired by the "lotus leaf effect" in nature, Barthlott and Neinhuis first synthesized a superhydrophobic coating, and its superior performance is derived from the surface of the coating. Due to the synergistic effect of chemical composition and surface structure, the surface layer can be constructed of low surface energy materials such as polytetrafluoroethylene, or an air pillow-like structure with high surface roughness can be introduced to increase the surface area. According to the "binary synergy" theory, sol-gel method, vapor deposition method, template method, electrochemical method, ion sputtering method and other methods can be used to construct a rough structure on the sur...
