A kind of infrared reflective heat insulation coating and preparation method thereof

Abstract

The invention relates to an infrared reflection thermal insulation coating, comprising the following raw materials in percentage by weight: 40-60% of film forming emulsion, 6-12% of rutile titania, 2-3% of thermal insulation filler, 6-12% of phosphogypsum whiskers, 1.5-5% of film forming additive, 1-5% of defoaming agent, 0.5-2% of thickening agent, 0.1-1% of dispersing agent and 15-35% of water. The coating can reflect visible light and infrared ray in sunlight to achieve the aims of saving energy and reducing consumption; in addition, the coating is favorable in elasticity and has waterproof and decorative effects.

Description

technical field

[0001] The invention relates to an infrared reflective heat-insulating coating and a preparation method thereof, which are mainly used for exterior walls of buildings. Background technique

[0002] Building energy consumption is an important part of my country's total energy consumption, accounting for about 1 / 3 of the whole society's energy consumption, which is 2-3 times that of developed countries. my country's construction industry is developing rapidly, and most of my country's buildings are high-energy non-energy-saving buildings. During use, heating, air conditioning, hot water supply, etc. consume a lot of energy. If no building energy-saving measures are taken, it is estimated that my country's building energy consumption will reach 108.9 billion tons of standard coal by 2020; Amazing amount. The goal of my country's building energy conservation is that by 2020, the total energy consumption of buildings in the whole society will reach 65% energy sav...
