[0009] CN104017495A discloses a composite heat-insulating coating, which conceptually designs a coating that integrates three heat-insulating methods of reflection, radiation, and barrier, and uses functional materials such as nano-titanium dioxide, anti-oxidation and anti-aging agents, and anti-ultraviolet agents. It can be seen from the composition that the coating cannot achieve three heat insulation effects of reflection, radiation and barrier at the same time

Abstract

The invention provides a building coating with a heat insulation function and a preparation method thereof. The building coating with the heat insulation function is divided into an internal wall coating and an external wall coating, wherein each of the internal wall coating and the external wall coating is composed of a basic carrier for film forming of the coating, a heat insulating material, a heat reflecting material, a heat radiating material, filler, an assistant and water. The preparation method comprises the following steps: preparation of heat insulating material slurry, preparation of function material slurry, grinding of slurry, and paint mixing. The film forming thickness of the building coating is 0.2-0.3mm, so that the building coating belongs to a thin building energy-saving coating; the internal and external wall building coatings have higher heat conducting resistance and lower convection heat transfer, so that the building coating has different heat radiating effects under different temperature environments in different seasons and has the heat insulation function; the building coating is high in safety and long in service life; and the preparation method is simple and is suitable for industrial production.

Description

technical field [0001] The invention relates to an architectural coating and a preparation method thereof, in particular to an architectural coating with heat insulation function after coating the outer surface and the inner surface of the outer wall of a building and a preparation method thereof. Background technique [0002] my country's existing buildings are about 50 billion square meters, and more than 95% of the buildings are high-energy buildings compared with developed countries. However, my country's building energy consumption accounts for about 30% of the total energy consumption of the society, and building energy consumption has an increasing trend every year. Building energy consumption includes building construction energy consumption and building use energy consumption. Among them, building construction energy consumption is one-time energy consumption, and building use energy consumption belongs to annual energy consumption. Therefore, building energy consu...
