Problems solved by technology
[0006] In view of the above existing problems or deficiencies, in order to solve the problems of relatively high raw material prices of existing superhydrophobic materials and the difficulty of large-scale application due to the limitation of technology, the present invention provides a superhydrophobic, highly stable nano-ceramic coating and its application method. Starting from the current limitations of super-hydrophobic coating technology that is difficult to apply and promote in a large area, and taking into account economy and practicability, the ratio of raw materials and application difficulty are improved, and at the same time, super-hydrophobic coatings are realized with low unit price, fast curing, simple large-area application and high stability

Embodiment
[0030] Step 1. Prepare materials:
[0031] Mix boehmite nano powder, polydimethylsiloxane, platinum catalyst, bisphenol A type epoxy resin, and ethyl acetate to obtain coating component A.
[0032] A coating component B was obtained by mixing hydrogen-containing silicone oil, diethylenetriamine, and an adduct of butyl glycidyl ether.
[0033] Step 2. Add all the coating components A and B prepared in step 1 into the beaker, and then perform ultrasonic mixing for 3 minutes.
[0034] Step 3, then put the paint obtained in step 2 into the spray gun, and evenly spray it on the surface of the aluminum plate.
[0035] Step 4. Put the aluminum plate sprayed in step 3 into an oven, set the temperature of the oven at 60° C., and keep it warm for 2 hours, and then obtain a hydrophobic nano-ceramic coating.
[0036] Table 1 is the coating components of 8 groups of embodiments and the corresponding obtained coating properties. The unit of the content of each component in the table is g...

Abstract
The invention belongs to the technical field of super-hydrophobic materials, and relates to a super-hydrophobic and high-stability nano ceramic coating and an application method thereof. According to the invention, the boehmite material used as a lithium battery diaphragm material is used as a component of the super-hydrophobic coating, and a micro-nano structure of the super-hydrophobic material is formed on the surface when the boehmite material is prepared into a coating by utilizing a unique crystal structure of the boehmite material; and boehmite has the characteristics of uniform and stable dispersion, large specific surface area and low cost, so that during later material application, a component A and a component B are simply dispersed and uniformly mixed in proportion, then the mixture is coated on the surface of a target object, and the super-hydrophobic and high-stability nano ceramic coating with high stability can be formed after curing. The super-hydrophobic coating provided by the invention is low in price, simple in application method and short in process period, can be applied to various substrates, is easy to popularize and use in a large scale, can be applied to scenes such as oceans, coastal areas and ships, and can well realize anti-icing, self-cleaning and corrosion resistance.
Description
technical field [0001] The invention belongs to the technical field of superhydrophobic materials, and relates to a superhydrophobic and highly stable nano-ceramic coating and its application method. Background technique [0002] Although the commercial hydrophobic or anti-icing coatings on the market have the characteristics of easy preparation, fast curing and certain hydrophobicity, in general, the unit price is too high, and the most important aspect of hydrophobicity can only achieve ordinary hydrophobicity. , it is difficult to achieve anticorrosion similar to ship materials and antifreeze for fan blades; in addition, hydrophobic materials are composed of polymers, and under long-term ultraviolet radiation, the materials will age, resulting in a decrease in stability. Therefore, superhydrophobic and inexpensive coating technology that can be applied to multiple environments needs to be developed urgently. [0003] In addition, the preparation of coatings is a key tech...
