Problems solved by technology

In recent years, with the development of phosphorus chemical enterprises, the discharge of phosphogypsum is increasing day by day. The annual by-product discharge of phosphogypsum in many key phosphorus chemical enterprises reaches 1 million to 2 million tons, but most of the phosphogypsum is in a state of stockpiling. Phosphogypsum has become a bottleneck restricting the development of phosphorus chemical industry and a major problem in environmental protection

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...
