Abstract
The invention provides an antifouling paint, an antifouling coating and a preparation method thereof, and relates to the technical field of functional materials. The antifouling paint is prepared from the following raw materials: a hexamethylene diisocyanate tripolymer, amino-terminated polydimethylsiloxane, N, N-dimethylformamide, methylated melamine formaldehyde resin and a p-toluenesulfonic acid aqueous solution. The antifouling paint provided by the invention has the advantages of easily available raw materials, simple preparation method, low cost, no fluoride harmful to the environment, and environmental friendliness; The antifouling paint is wide in application range and can be applied to various types of base materials, and the obtained coating is high in transparency and does not affect the appearance of the base materials. The antifouling coating provided by the invention has wide liquid repellency and good self-cleaning performance, pollutants such as dust on the surface of the coating can be easily washed away by water and some oily liquid drops, and the antifouling coating has the advantages of high transparency, high smoothness, high hardness, flexibility, wear resistance, acid, alkali and salt resistance, corrosion resistance, ultraviolet radiation resistance and good environmental durability.
Description
technical field [0001] The invention relates to the technical field of functional materials, in particular to an antifouling coating, an antifouling coating and a preparation method thereof. Background technique [0002] Antifouling coatings have many potential application values. For example, glass walls used in high-rise buildings can keep the walls clean for a long time, avoiding accidents caused by manual high-altitude scrubbing and waste of water resources; Muddy water pollutes the car body, and rainwater can easily wash away the dust on the car body, reducing the number of artificial car washes and saving water resources; used for windshields of cars, airplanes, and ships, which can improve the vision of vehicles during driving and improve driving safety ; Used in solar panels can reduce the accumulation of dust and increase conversion efficiency. [0003] In recent years, researchers have made great progress in the research of this kind of materials in terms of resea...
