Problems solved by technology

However, the current building energy-saving and thermal insulation measures are only aimed at the outer envelope of the building. Generally, no thermal insulation measures are used between the partition walls of the buildings in the building. In this way, different buildings may have different temperatures, resulting in thermal pressure. A room experiences heat loss, the flow of heat from a warmer room to a cooler room
This unfair phenomenon of heat use is likely to cause various problems and contradictions. For example, the heat loss in the household is serious, which makes the heat use uneven among neighbors, resulting in unfair phenomena, and has high building energy consumption, thus Influenced the promotion of my country's building energy conservation policy

Abstract

The invention provides interior wall thermal insulation coating. The interior wall thermal insulation coating comprises the following components in parts by weight: 5-45 parts of water, 3-25 parts of auxiliaries, 3-55 parts of inorganic fillers, 5-55 parts of coating resin and 1-30 parts of doped semiconductors and metal-clad hollow microspheres. The interior wall thermal insulation coating has the beneficial effects that as the doped semiconductors are used, the wall surface coated with the coating has a low thermal radiation absorption coefficient and a low high thermal storage coefficient and the temperature of the wall surface can rise; the indoor temperature is also increased while the wall temperature rises, thus greatly improving the thermal comfort degrees of rooms and improving the indoor thermal insulation effect; the metal-clad hollow microspheres have high infrared reflectivity and low emissivity and have a certain thermal reflection effect; and as the metal-clad hollow microspheres have hollow structures and a low thermal conductivity coefficient, the thermal conductivity coefficient of the coating is reduced and the mid-far infrared thermal ray blocking capacity of the thermal insulation coating is substantially promoted, thus improving the indoor thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a thermal insulation coating for interior walls. Background technique [0002] At present, the heating method commonly used in my country is mainly radiator convection heating mode, such as floor heating, radiators, etc. Radiation heating systems such as infrared electrothermal film are gradually popularized because of more uniform heat distribution and higher thermal efficiency on the human body and other objects. Indoor heat conduction is mainly radiation and convection. Regardless of whether convection heating or radiation heating is used, heat radiation plays an important role in the indoor heat effect. When heat radiation reaches the surface of the wall, it will be absorbed by the wall and be lost to the outside. [0003] Heating energy consumption in winter is the main energy consumption of Chinese buildings, and the Chinese government has continuously ...
