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 superhydrophobic materials, and relates to a superhydrophobic and highly stable nano-ceramic coating and its application method. In the present invention, the boehmite material used as a lithium battery separator material is used as a component of a superhydrophobic coating, and its unique crystal structure is used to form a micro-nano structure of a superhydrophobic material on the surface when it is prepared into a coating; and Because boehmite has the characteristics of uniform dispersion and stability, large specific surface area and low cost, in the later application of materials, its component A and component B are simply dispersed and mixed in proportion, and then coated on the surface of the target object. After curing, a highly stable super-hydrophobic and highly stable nano-ceramic coating can be formed. The superhydrophobic coating provided by the present invention is cheap, simple to use, and has a short process cycle, and can be applied to various substrates, easy to be popularized and used on a large scale, and can be applied to scenes such as oceans, coastal areas, and ships, and can be well realized Freeze-resistant, self-cleaning and corrosion-resistant.
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...
