Abstract

The invention provides a technology-based ultra-wide wave infrared thermal insulation coating, comprising the following components: acrylic resin, polycopper carbosilane, infrared reflector, curing agent, auxiliary agent, curing accelerator and solvent. Polycopper carbosilane has a relatively complete crystal structure, so it has strong infrared reflection ability; the infrared reflector is made of a mixture of amorphous selenium powder, hematite powder and reddish silver mineral powder with a certain particle size with high refractive index. This component is the sum of the three infrared reflection bands, and has ultra-wide wavelength infrared reflection properties, which enables the coating to achieve excellent thermal insulation effects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to ultra-wide wave infrared thermal insulation coatings. Background technique [0002] Building envelope energy saving has been applied for a long time. The main method is to paste materials with small heat transfer coefficient and large thickness, commonly known as "wearing a cotton jacket", which is the heat conduction and heat insulation method. . This energy-saving method of conduction heat insulation, material testing and thermal calculation is very popular. But in practice, it is found that the problem is huge, the visible fire and falling off, and the invisible problem is more serious. China is a vast country, with huge differences in climate between the north and the south, and the four distinct seasons. A single "padded jacket" is no problem in winter, but there is a big problem in summer. Not only does it not save energy, but it consumes energy. The reason is very simp...
