Anti-freezing radiation heat-insulating coating and preparation method thereof

Abstract

The invention discloses an anti-freezing radiation heat-insulating coating which is characterized by being made from following raw materials, by weight: 21-23 parts of a cordierite-based composite infrared radiation material, 40-43 parts of pure acrylic emulsion, 21-23 parts of anhydrous alcohol, 8-9 parts of rutile titanium dioxide, 1-2 parts of sodium polyacrylate, 2-3 parts of hydrogenated castor oil, 8-10 parts of mica powder, 1-1.5 parts of urea, 0.8-1 part of propylene glycol, 1-2 parts of lauryl sodium sulfate, 27-30 parts of deionized water, and 0.6-0.8 parts of glyceryl stearate. In the coating, the cordierite-based composite infrared radiation material is employed as a filling material so that the infrared emitting rate can be increased, and the coating is better in heat insulation and temperature reduction, can reduce indoor / outdoor temperature difference and is energy-saving and environmental-protective. The coating contains the urea and the propylene glycol, so that the coating is improved in anti-freezing performance and is prolonged in service life. In the coating, the mica powder and the like components are activated and then are mixed with other components, so that the coating is fine and compact in film, is high in infrared emitting rate, is beneficial to heat insulation and temperature reduction, is energy-saving and environmental-protective and can reduce the indoor / outdoor temperature difference.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a frost-resistant radiation heat-insulating coating and a preparation method thereof. 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 accounts for about 27% of the country's total energy consumption, ranking first among all types of energy consumption in the country. Heating and air conditioning energy consumption accounts for 55% of the total building energy consumption, and it is increasing at a rate of 1% per year. Therefore, the research and development of building thermal insulation coatings has significant economic, environmental and social benefits. The use of coatings with heat insulation function on the exterior walls of buildings can not only ...

AI Technical Summary

Problems solved by technology

[0004] The heat insulation coatings currently used have the following disadvantages: the coating is aged by the sun's ultraviolet rays all the year round; the temperature is too low in winter, which leads to the pulverization of the coating and the bottoming phenomenon

As a result of the combined effect of the above problems, the heat insulation effect of the coating film will be deteriorated and the service life will be shortened.
