Interior wall putty with dehumidification and humidification functions

Abstract

The invention discloses interior wall putty with dehumidification and humidification functions. The interior wall putty is prepared from the following raw materials in parts by weight: 20-24 parts of humidifying material, 26-28 parts of light weight calcium, 32-34 parts of heavy calcium, 8-10 parts of puffed corn starch, 3-5 parts of sodium gluconate, 2-4 parts of carboxy methyl cellulose, 0.3-0.4 part of carbon fiber with the length of 3-5mm, 7-9 parts of white cement and 20-24 parts of water, wherein the humidifying material comprises diatomite and sepiolite, the weight ratio of the diatomite to the sepiolite is 5:(2-3), and the granularities of both the diatomite and the sepiolite are no more than 200 meshes. The interior wall putty disclosed by the invention can absorb moisture in air so as to reduce humidity during high air humidity and release moisture so as to increase humidity during low air humidity.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an interior wall putty with dehumidification and humidification functions. 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. [0003] 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 air air cond...

Problems solved by technology

A Chinese patent application discloses a moisture-regulating material for textiles and walls, which is composed of a biocatalyst, a 2-5nm mesoporous material (sepiolite, diatomite, attapulgite, etc.) and a 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 disadvantage of limited moisture release, and there are still technical obstacles in direct use

[0005] Adding the existing humidity control materials directly into the putty powder cannot play the role of humidity control, but needs to be formulated from the compatibility of all components. Therefore, there is still no high-quality and environmentally friendly putty products with humidity control functions on the market.
