Nano thermal insulation coating

Abstract

The invention discloses nano thermal insulation coating which comprises the following components in part by weight: 25 to 40 parts of nano-aluminum phosphate, 10 to 15 parts of acrylate emulsion, 5 to 10 parts of nano manganese oxide, 2 to 8 parts of nano-zirconia, 3 to 7 parts of nano titanium carbonitride, 1 to 5 parts of sodium dioctyl sulfosuccinate, 9 to 14 parts of lauryl sodium sulfate, 21 to 28 parts of polyvinyl alcohol, 11 to 14 parts of nano perlite, 4 to 9 parts of nano calcium silicate powder, 5 to 7 parts of polypropylene fibre, 7 to 16 parts of nano beta-hemihydrate gypsum powder, and 30 to 35 parts of water. The nano thermal insulation coating improves comprehensive performances of the coating, such as heat insulation property, washability, antibacterial self-cleaning property and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation material preparation, and in particular relates to a nano thermal insulation coating. Background technique [0002] Applying nanotechnology and nanomaterials to coatings can use the principle of double vegetables in lotus leaves and nano-effects such as "zero convection" to improve the thermal insulation, water resistance and mildew resistance of coatings. Aluminum silicate is a material with good high temperature resistance and good heat insulation performance, and nano-aluminum silicate has good suspension stability due to its small particle size, narrow particle size distribution, and no precipitation and stratification. Dispersion and fineness indicators, so that the appearance, gloss, hardness and dispersion of the coating have good effects. The use of nano-aluminum silicate in the coating can make the coating produce nano-effects such as "zero convection", which greatly reduces t...

Problems solved by technology

There are also people who add nano-components to improve the quality of coatings. For example, the invention patent No. 03118030.2 uses pure acrylic emulsion as the base material and adds nano-scale zinc oxide, silicon oxide and titanium oxide. Scrub resistance, antibacterial and self-cleaning functions, but the thermal insulation effect is poor, and the production process is more complicated
