Problems solved by technology

[0003] Although the existing heat-reflective and heat-insulating coatings also have heat-reflecting substances and heat-insulating substances, most of the film-forming substances are acrylic resins, polyester resins, fluorosilicone resins, epoxy resins, etc., and the main film-forming substances are relatively single. Comprehensive performance is not good enough
Generally speaking, under the same base material conditions, the filler plays a leading role in the reflective thermal insulation effect of reflective thermal insulation coatings, among which the filler is an important part of the coating, and its selection is the key to the preparation of high-efficiency reflective thermal insulation coatings One, the reflective heat-insulating coatings in the prior art mainly use glass microspheres or ceramic microspheres as functional substances for heat insulation, which have the disadvantages of poor heat insulation performance, poor storage stability, high price and inconvenient construction.

Abstract

The invention discloses a reflection thermal insulating coating which comprises the following components in parts by mass: 50-60 parts of an organic silicon phosphate type filming ion polymer, 7-12 parts of mesoporous silica, 7-12 parts of aluminum oxide nanotubes, 10-15 parts of a solvent and 3-6 parts of functional aids. Compared with a common reflection thermal insulating coat in the prior art,the reflection thermal insulating coating disclosed by the invention is more excellent in comprehensive property such as weather resistance, binding force with buildings and chemical resistance, andis relatively remarkable in reflection thermal insulating effect.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a reflective heat-insulating coating for exterior walls of buildings. Background technique [0002] With the rapid development of my country's construction industry and the increasingly prominent energy crisis, the energy saving and consumption reduction of buildings is becoming more and more important. my country's building energy consumption ranks first among all types of energy consumption in the country. The use of coatings with heat insulation function on the exterior walls of buildings is an effective way to save energy and reduce consumption of buildings. It can not only keep the indoor temperature constant and increase the temperature difference between indoor and outdoor, but also realize the original decoration, protection and mildew resistance of the coating. and other functions. [0003] Although the existing heat-reflective and heat-insulating coatin...
