Abstract

The invention discloses a high-reflection thermal insulation coating. The high-reflection thermal insulation coating comprises a priming paint layer and a finishing paint layer, wherein the priming paint layer contains the following components (in parts by weight): 10%-15% of rutile titanium dioxide with the average grain diameter of 300nm, 10%-20% of hollow glass bead with the average grain diameter of 300nm, 5%-10% of talcum powder with the average grain diameter of 200nm, 40%-50% of organic silicone modified acrylic acid and 15%-20% of purified water; and the finishing paint layer containsthe following components (in parts by weight): 3%-12% of kaolin with the average grain diameter of 10 microns, 3%-12% of rutile titanium dioxide with the average grain diameter of 10 microns, 10%-25%of hollow glass bead with the average grain diameter of 20 microns, 5-10% of talcum powder with the average grain diameter of 20 microns, 0.5-1.5% of ferrous chloride, 40%-50% of organic silicone modified acrylic acid and 15%-20% of purified water. The invention aims at providing the high-reflection thermal insulation coating. The coating has the effects of ultralow heat conductivity coefficient,good thermal insulation property, good flexibility, durability and contamination resistance and safety and convenience in construction.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to a high-reflection heat-insulating coating. Background technique [0002] Solar reflective heat insulation coatings for buildings use the properties of coating components that have high reflectivity for most wavelengths in the radiation spectrum from the sun to reduce the temperature of the outer walls of buildings, reduce the temperature difference between indoors and outdoors, and thereby reduce heat transfer. The driving force makes the indoor temperature lower than the indoor temperature of the cement wall or ordinary paint wall, reduces the power consumption of refrigeration equipment, and achieves the effect of energy saving. [0003] The energy of sunlight is mainly concentrated in visible light and near-infrared rays, which account for more than 90% of solar energy. When the sunlight is projected onto the surface of an object, it follows the law of visible light and ha...
