Optical and thermal radiation-resisting nano-composite metal surface paint and preparation method thereof

Abstract

The invention relates to an optical and thermal radiation-resisting nano-composite metal surface paint, which consists of pure acrylic emulsion, a pigment, a filler, titanium dioxide, nano radiation-resistant slurry, ethylene glycol, 2,2,4-trimethyl-1,3-pentanediol-mono-isobutyrate (Taxanol), polyacrylate, water, a thickener and other auxiliary agents. The invention is characterized by special components and preparation method of the paint, and provides an environmentally-friendly optical and thermal radiation-resisting nano-composite metal surface paint of which the solar radiation reflectivity is over 84.4 percent at 410 to 1,000nm, and a preparation method thereof.

Description

technical field [0001] The invention relates to a coating material used on a metal surface and a preparation method thereof, in particular to a photothermal radiation-resistant nanocomposite metal surface coating capable of reflecting light and heat radiation on a metal surface through a special production method and a preparation method thereof Background technique [0002] Most of the steel plate and steel structures currently on the market, such as color steel roofs, metal storage tanks, granary oil tanks, petrochemical pipeline surfaces, containers, refrigerated vehicles, prefab buildings, car driving rooms, board houses, etc., do not have the function of heat insulation. Parts with heat insulation and cooling function are often painted with silver powder paint, but silver powder paint not only has poor heat insulation performance, but also needs to be sprayed with water to cool down in hot summer, which consumes a lot of water, electricity and energy. At the same time, s...

Problems solved by technology

[0002] Most of the steel plate and steel structures currently on the market, such as color steel roofs, metal storage tanks, granary oil tanks, petrochemical pipeline surfaces, containers, refrigerated vehicles, prefab buildings, car driving rooms, board houses, etc., do not have the function of heat insulation. Parts with heat insulation and cooling function are often painted with silver powder paint, but silver powder paint not only has poor heat insulation performance, but also needs to be sprayed with water to cool down in hot summer, which consumes a lot of water, electricity and energy. At the same time, silver powder paint is an oil-based paint. , strong environmental hazard

[0003] There are still problems with the metal heat insulation coatings that have emerged recently. The nano heat insulation reflective coatings for grain and oil warehouses with patent application number 03117347.0 use vermiculite, sepiolite, ceramic bubbles, floating beads, expanded perlite, etc. as the main heat insulation materials. Reduce heat insulation coefficient to achieve cooling effect; patent application number is 02109969.3 acrylic nano microemulsion, water-based heat-reflective heat-reflective coating and its manufacturing method and patent application number is 03111863.1 water-based epoxy modified acrylic heat-reflective heat-resistant coating, although Compared with the previous oil-based paint, it has been improved, but its use environment still uses organic solvents, which has not reached the true sense of environmental protection
