Embodiment Construction

[0020] 1. First use a part of ethyl acetate and n-butanol to adjust the concentration of polytetrafluoroethylene resin and polyvinyl butyral, adjust to apply four cups for 25 seconds, and then seal the high temperature chelation. The temperature of chelation is 150 ℃, and the time 60 minutes. After cooling, the viscosity of the solution will increase, turn on the stirring, and then add some ethyl acetate and n-butanol to dilute to adjust the viscosity.

[0021] 2. Add various additives to the resin solution, stir, and then add titanium dioxide, talc powder, and light calcium powder in turn and stir. The stirring speed should reach 5000 rpm, high-speed stirring, and the stirring time should be more than 30 minutes.

[0022] 3. Finally, add the remaining various additives and stir evenly.

Abstract

A self-cleaning nano coating has high adhesion ability, high film hardness and toughness, excellent self-cleaning function, high anti-dust and anti-dirt adhesion ability, excellent hydrophobicity and high probability of dirt cleanness and is environment-friendly. The self-cleaning nano coating is prepared from a nano-structure material with an IPN (interpenetrating polymer network) technology. Through simulation of a lotus leaf water repellent principle, invasion of dust and oil dirt is effectively prevented, and pollutants are easily taken away through rainwater washing, so that the coating is clean and looks new for a long time; the self-cleaning nano coating can be applied to surfaces of materials including ordinary glass, organic glass, plastics, ceramics, metals, textile and the like and has a self-cleaning effect.

Description

technical field [0001] Nano self-cleaning coating is an environmentally friendly and clean coating that has hydrophobic physical properties and can play the role of easy cleaning and self-cleaning independently developed by Beijing Zhisheng Weihua Chemical Co., Ltd. It has the technical advantages of high light transmittance, nanoscale, and single effective crystal form. Background technique [0002] In recent years, air pollution has become more and more serious. Dust, moisture, oil pollution, automobile exhaust and other substances in the atmosphere will seriously pollute the outer walls of urban buildings and architectural glass, making them eclipsed and difficult to clean in large areas, which is time-consuming and laborious. . With the continuous improvement of people's requirements for quality of life and the continuous enhancement of environmental protection and energy-saving awareness, the surface with self-cleaning function has been developed rapidly. A self-clean...
