Abstract

The invention discloses a heat-insulating coating for an inner wall. The heat-insulating coating comprises the following components in percentage by weight: 20 to 40 percent of acrylic acid latex, 0.1 to 5 percent of moistening agent, 0.1 to 5 percent of dispersing agent, 5 to 20 percent of diatomite, 5 to 10 percent of hollow glass microsphere, 5 to 25 percent of titanium white powder, 0.1 to 5 percent of thickening agent, 1 to 10 percent of swelling microsphere, 3 to 10 percent of opaque polymer and 20 to 40 percent of water. The novel heat-insulating coating for the inner wall has the characteristics of slow temperature rise during heating and slow temperature drop during heat emission, and can properly adjust the indoor temperature and make the housing environment more comfortable; and, the aqueous latex is used, so that the heat-insulating coating is safe to the human body and the environment, and belongs to green environmentally-friendly product.

Description

technical field [0001] The invention relates to a thermal insulation coating for interior walls. Background technique [0002] Saving energy, reducing consumption, and improving economic benefits are one of the basic goals of scientific research and technology development, and coating technology is no exception. After the 1970s, the world's climate became warmer, and the earth's energy sources were increasingly exhausted. In my country's energy consumption, building energy consumption accounts for about 1 / 4 of the national energy consumption, while building insulation materials only account for about 11% of the total. It can be seen that building energy conservation has great potential. Under the background of vigorously popularizing heat insulation materials in foreign countries, it can be predicted that my country will gradually introduce laws and regulations that require heat insulation measures for new houses. Among building heat insulation materials, building heat ins...
