Abstract

The invention provides a technology-based ultra-wide-amplitude infrared thermal insulation coating. The technology-based ultra-wide-amplitude infrared thermal insulation coating comprises the following components: acrylic resin, polycopper carbosilane, an infrared reflecting agent, a curing agent, an auxiliary agent, a curing accelerator and a solvent. The polycopper carbosilane has a relatively complete crystal structure, so that the polycopper carbosilane has relatively strong infrared reflection capability; the infrared reflecting agent is prepared from a mixture of amorphous selenium powder, hematite powder and light red silver ore powder with high refractive index and certain particle size, and the component integrates the sum of infrared reflection bands of the amorphous selenium powder, the hematite powder and the light red silver ore powder and has ultra-wide-amplitude infrared reflection performance, so that the coating can achieve excellent effects of heat preservation and heat insulation.

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] The energy saving of building envelope structure has been applied for a long time. The main method is to add materials with small heat transfer coefficient and large thickness, commonly known as "wearing cotton jacket", which is the heat conduction insulation method, which requires heat insulation materials with small heat transfer coefficient and large thickness. . This conduction heat insulation energy-saving method, material detection and thermal calculation are very popular. But in practice, it is found that there are huge problems. The visible ones are fire and falling off, while the invisible ones are more serious. China has a vast territory, with huge differences in climate between the north and the south, and four distinct seasons. A single "padded jacket" is no problem in winter, but i...
