Problems solved by technology

Although the current building thermal insulation coatings have thermal insulation effect, there are generally the following problems: (1) The fire-proof and flame-retardant effect is poor. Since the base material is made of polymer, the polymer itself is easy to burn, so the coating cannot achieve the effect of fire-proof and flame-retardant , a hidden danger to safety
(2) The decorative effect is poor. The coatings of thermal insulation coatings currently available on the market are all thicker to achieve good thermal insulation effects, so they cannot achieve a good decorative effect, which limits their application

Abstract

The water-based flame-retardant heat-insulating and heat-insulating paint and a preparation method thereof relate to a building paint and provide a building heat-preserving paint integrating flame-retardant performance, heat-preserving performance and decorative functions. The coating is composed of emulsion, flame retardant, titanium dioxide, hollow glass microspheres, water and additives. The components are emulsion 35-40, flame retardant 20-30, titanium dioxide 15-20, hollow glass Microbeads 5-10, water 19-21, additives 11-15. Using a variety of inorganic, phosphorus, and nitrogen flame retardants, taking advantage of the synergistic effect between different flame retardants, can achieve flame retardant effects with a small amount of use, while not affecting the physical properties of the paint coating; Glass beads are used to reduce thermal conductivity, heat convection and heat radiation to obtain thermal insulation performance. The coating thickness is about 1mm to achieve a good thermal insulation effect. The thermal insulation and flame retardant properties of the coating are reflected in the thermal conductivity ≤ 0.090W / (mk), and the oxygen index ≥ 28.0%.

Description

technical field [0001] The invention relates to a building coating, in particular to a coating with flame-retardant, heat-insulating and heat-insulating functions and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and social production, energy and the environment have become two major issues of increasing concern to the whole society, thus putting forward higher requirements for energy saving and environmental protection. The world's energy demand is growing at a rate of 2% per year, and about 30% of this energy is consumed in buildings. In our country, building energy consumption together with the energy consumption of envelope structure materials has accounted for 27.6% of the total energy consumption in the country, and will gradually increase to more than 33% with the improvement of people's living standards. Energy efficiency in buildings is an effective way to improve building energy efficiency. Among ...
