A kind of interior wall insulation coating

Abstract

The invention provides interior wall heat-insulating paint which comprises the following components in parts by weight: 5-45 parts of water, 3-25 parts of assistant, 3-55 parts of inorganic filler, 5-55 parts of paint resin and 1-30 parts of infrared reflection pigment and metal-coated hollow microsphere, wherein for the infrared reflection pigment, the refractivity is more than 2.0, and the particle size is no less than 1mu m. In the invention, the infrared reflection pigment of which the refractivity is more than 2.0 and the particle size is no less than 1mu m ensures that most of the heat energy absorbed by the surface of a wall can be instantaneously reflected back indoors, thus improving the indoor heat-insulating effect; and the metal-coated hollow microsphere has high infrared reflectivity and low emissivity, is in a hollow structure and is low in heat conductivity coefficient, so that the heat conductivity coefficient of the paint is reduced, and the middle and far infrared heat ray blocking capability of a heat-insulating coating is greatly enhanced, thereby improving the indoor heat-insulating 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 ...

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
