Inorganic putty powder with function of governing humidness

Abstract

The invention relates to interior wall putty powder with air humidity regulating function, which belongs to the field of building materials. The putty powder is composed of 10 to 50 weight portions of humidity regulating material, 15 to 50 weight portions of inorganic binding material, 15 to 50 weight portions of inorganic filler, and 1 to 5 weight portions of sub divisible rubber powder; the humidity regulating material comprises one type or more than one type of diatomite, sepiolite, attapulgite, vermiculite, zeolite powder, kaolin and bentonite. Because of the environment protection and humidity regulating functions, the multi-pore inorganic mineral material is taken as humidity regulating material and applied in the building interior wall putty powder. With water added in, the putty powder is mixed into lacquer putty and applied on the wall surface, which can effectively regulate the indoor air humidity, so that the indoor air humidity is controlled within the scope which is beneficial to the health of human body; meanwhile, the putty powder has no pollution, no VOC released and can be directly used for decoration.

Description

technical field [0001] The invention relates to building decoration materials, in particular to an interior wall putty powder which can effectively adjust the relative humidity of the indoor environment. Background technique [0002] In daily life, too high humidity will make people feel chest tightness and difficulty breathing, and too high humidity is conducive to the growth of bacteria; when the humidity is too low, the air will appear dry, and items will easily dry out and so on. In recent years, as people's requirements for living comfort are increasing day by day, the influence of humidity level on human living environment has been paid more and more attention. In order to pursue a relatively comfortable humidity environment, people use many methods to control humidity, the most common ones are the use of humidifiers and air conditioners. However, these mechanical control of humidity requires a lot of energy, and the lack of ventilation in the room when using no fresh ...

AI Technical Summary

Problems solved by technology

Chinese patent application 200610099093.3 discloses a moisture-regulating material for textiles and walls, which is composed of biocatalyst, 2-5nm mesoporous materials (sepiolite, diatomite, attapulgite, etc.) and superabsorbent resin , the humidity control range is 35-75% relative humidity, in which the superabsorbent resin plays the role of humidity control, and the mesoporous material is the carrier of other components. The humidity control material has a large amount of moisture absorption, but still has poor moisture absorption and release characteristics The defect of limited moisture absorption and desorption, and there are still technical obstacles in direct use

Traditional putty has fatal shortcomings such as low strength, high water absorption, loose texture, and formaldehyde content, which cannot meet the increasing use requirements; It needs to be adjusted from the compatibility of all components. Therefore, there is still a blank in the market for high-quality and environmentally friendly putty products with humidity control functions.
