Abstract

The invention discloses a composite architectural heat-insulation coating and a preparation method thereof. The composite architectural heat-insulation coating is formed by mixing the following ingredients by mass: 25 to 40 parts of water, 0.3 to 0.9 part of a thickening agent, 0.1 to 0.3 part of a multifunctional additive, 0.3 to 1.2 parts of an ageing resistant additive, 0.2 to 0.5 part of a wetting agent, 0.5 to 2.0 parts of a dispersing agent, 0.4 to 1.3 parts of a mold inhibitor, 0.2 to 0.5 part of an antifoaming agent, 2 to 5 parts of a film-forming additive, 8 to 20 parts of a pigment, 6 to 13 parts of a heat-insulation functional additive formed by mixing two or three of phase change microcapsules, hollow glass microspheres and polymeric microspheres, and 38 to 52 parts of an emulsion. The composite architectural heat-insulation coating is favorable in appearance, excellent in storage stability, equal to or lower than 1.06 g / cm<3> in density, equal to or lower than 0.065 W / (m.k) in heat conductivity, larger than 10 DEG C in heat-insulation temperature difference, favorable in washability and brushability, and excellent in heat-insulation effect.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a composite building thermal insulation coating and a preparation method of the building thermal insulation coating. technical background [0002] With the development of economy, the global demand for energy is increasing day by day. During the use of buildings, a large amount of energy is consumed in heating, air conditioning, ventilation, hot water supply, etc. These energy sources account for about 30% to 40% of the total energy consumption of human beings. Facing the increasingly tense energy sources, the issue of building energy conservation has caused more and more problems. attention of more and more countries. Practice has proved that the most direct and effective way to save energy in buildings is to use thermal insulation materials. According to the energy-saving practice in Japan, every 1t of thermal insulation materials used can save 3t of standard coal per year, and i...
