Aqueous flame-retardant and thermal-insulated coating and preparation method thereof

Abstract

The invention discloses an aqueous flame-retardant and thermal-insulated coating and a preparation method thereof, relates to a building coating, and provides a building thermal-insulated coating integrating flame-retardant property, thermal-insulated property and decorative function. The coating consists of emulsion, a fire retardant, titanium, hollow glass beads, water and assistants, with the respective mass parts being 35-40, 20-30, 15-20, 5-10, 19-21 and 11-15. The coating uses fire retardants of inorganic type, phosphorus type and nitrogen type and utilizes synergistic action among different fire retardants to achieve the retardant effect with less amount and without influencing the physical properties of the coating layer; better thermal-insulated effect can be achieved when the thickness of the coating layer is about 1mm through obtaining thermal insulation property by reducing thermal conductivity, thermoconvection and thermal radiation through the glass beads; and the thermal-insulation and flame-retardant properties of the coating are reflected by that the heat conduction coefficient is not more than 0.090 w / (m.k), and the oxygen index is not less than 28.0 percent.

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 ...

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
