Problems solved by technology

[0002] With the rapid development of my country's economy, various materials are widely used in various fields in production and life, but a single material will inevitably suffer from corrosion, pollution and other problems during normal use, which will affect the service life of the material
Among them, the range hood made of aluminum alloy plate has been in the polluted atmosphere of oil fume for a long time, which is not only difficult to clean, but also affects the use and appearance.

Abstract

The invention discloses a preparation method of an oil-resistant self-cleaning coating, and relates to the technical field of new materials. The method comprises the following steps: performing ultrasonic treatment on an electrostatic spinning solution, performing secondary ultrasonic treatment on fibers sprayed from a syringe needle before reaching a negative electrode during electrostatic spinning, and enabling the negative electrode to be an aluminum alloy plate during electrostatic spinning, so that the fibers are directly generated on the aluminum alloy plate to form a crossed three-dimensional net-shaped coating; water on the surface of the coating falls off to take away part of oil stains, and the rest oil stains fall off automatically, so that the self-cleaning effect is achieved; and the aluminum alloy with the fiber prepared on the surface is soaked twice, the aluminum alloy is soaked in a foamed polyvinyl alcohol solution for the first time, the aluminum alloy is soaked in a polyvinyl alcohol silica sol solution for the second time and heated, the coating is firmly bonded to the surface of the aluminum alloy, and meanwhile the service life is prolonged.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a preparation method of an oil-stain-resistant self-cleaning coating. Background technique [0002] With the rapid development of my country's economy, various materials are widely used in various fields in production and life, but a single material will inevitably suffer from corrosion, pollution and other problems during normal use, which will affect the service life of the material . Among them, the range hood made of aluminum alloy plate has been in the polluted atmosphere of oil fume for a long time, which is not only difficult to clean, but also affects the use and appearance. Therefore, it is very promising to directly prepare a layer of coating on the aluminum alloy plate, which can not only easily clean the surface of the range hood, but also prevent oil pollution and self-cleaning. Contents of the invention [0003] The purpose of the present invention is to provide a me...
