Thermal-insulation and self-cleaning coating

Abstract

The invention discloses thermal-insulation and self-cleaning coating. The coating can be directly used on a metal exterior protection plate, has a good thermal-insulation effect, is environment-friendly, sanitary, convenient for cleaning, attractive and durable and can reduce construction workload of the thermal-insulation layer of a metal exterior protection plate. The coating comprises the following materials in percentage by weight: 60 to 90 percent of polyvinylidene fluoride, 5 to 10 percent of nano carbon tubes, 1 to 5 percent of titanium oxide, 5 to 10 percent of pigment and the balanceof additive. The invention can be widely used in the field of building materials.

Description

technical field [0001] The invention relates to a coating with heat-insulating and self-cleaning functions. Background technique [0002] With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal packaging and so on. At present, many new buildings adopt metal structure roofing systems, especially steel structure buildings, and their roofing systems naturally also adopt metal structure roofing systems. Composite metal roofing systems are more and more widely used in various industries, sports, entertainment, exhibition halls, retail supermarkets and other buildings. Metal roofing systems require the use of metal roof panels and metal structural base plates. Additionally, metal wall panels are now commonly used in various building systems. Coated metal panels used for wall or roof enclosures, including the above-mentioned metal roof panels, metal structural bottom panels and metal wall panels, can b...

Problems solved by technology

However, as the use time increases, impurities such as dust particles and harmful substances such as bacteria will adhere to the outer surface, but it is difficult to detect; and because the metal enclosure generally hangs high and is very troublesome to clean, the existing metal enclosure Fences are seldom cleaned on a regular basis; as time goes by, the surface of the metal fenders tends to get foggy and dark, affecting the aesthetics of the product

[0004] In addition, metal enclosures are used for enclosure. In summer when the temperature is high, the temperature of the enclosed indoor space will be high due to the heat absorption of the metal enclosures. In winter when the temperature is low, due to the heat conduction of the metal However, the temperature of the enclosed indoor space is too low. In order to overcome the influence of temperature, the method of adding heat insulation layer and heat insulation material is generally used for heat insulation, but this method not only takes up space, but also requires more installation work. Large, low installation efficiency
