Problems solved by technology

It can be seen that the self-cleaning coating material also relies on the self-cleaning effect of titanium oxide, and there are only resin materials and titanium oxide without other components. The performance of the coating material is single and unstable, and it is extremely vulnerable to external corrosion. Not conducive to the long-term use of the coating

Abstract

The invention provides a self-cleaning composite material and a preparation method thereof, and relates to the technical field of materials. The composite material is prepared from the following components in parts by mass: 25-40 parts of polyurethane resin, 10-15 parts of nano-titanium oxide, 5-10 parts of yttrium oxide, 4-8 parts of alkali metal sulfonate, 6-12 parts of poly(meta-ethylene acid ester), 6-15 parts of nano-tungsten oxide, 4-10 parts of white carbon black, 3-8 parts of polyoxyethylene ether, 6-12 parts of magnesium oxide ceramic micro-powder, 6-15 parts of glass fiber, 5-10 parts of a curing agent and 12-22 parts of acetone. The self-cleaning composite material provided by the invention has the advantages of excellent photocatalysis performance, excellent self-cleaning performance, stable property, good weather tolerance and durability and excellent mechanical performance, and can be used as a surface coating material of metal or alloy materials.

Description

technical field [0001] The invention belongs to the field of material technology, in particular to a self-cleaning composite material and a preparation method of the composite material. Background technique [0002] Nano self-cleaning materials refer to materials that keep themselves clean under natural conditions. The materials themselves have multiple functions such as anti-fouling, deodorizing, anti-bacterial, and anti-mildew. [0003] At present, the application range of self-cleaning materials includes the protection of various material surfaces, enhancing the anti-scratch ability of polymer surfaces, and being used for oil, dust, and pollution prevention. [0004] Nano self-cleaning materials are mainly self-cleaning coatings (films), and their self-cleaning performances are also different through different film materials and different components. Nano-titanium oxide is a commonly used self-cleaning material. Due to its photocatalytic, self-cleaning and antibacterial ...
