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
[0004] 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 a blank in the market for high-quality and environmentally friendly putty products with humidity control functions

Abstract

The invention discloses a preparation method of interior wall putty with dehumidification and humidification functions. The preparation method comprises the following steps of: S1, adding one third of 20-24 parts of water to a stirrer, then adding 2-4 parts of carboxy methyl cellulose and 0.3-0.4 part of carbon fiber with the length of 3-5mm, mixing uniformly, weighing diatomite and sepiolite in 20-24 parts of humidifying material at a ratio of 5:(2-3), adding the weighed diatomite and sepiolite to the mixture, controlling the stirring speed at 100-200r / m, and stirring for 10-15 minutes to obtain a mixture A; step two, adding another one third of water to another stirrer, adding 26-28 parts of light weight calcium, 32-34 parts of heavy calcium, 8-10 parts of puffed corn starch and 3-5 parts of sodium gluconate to the stirrer, and stirring for 10-15 minutes to obtain a mixture B; step three. adding the mixture A to the mixture B, then adding 7-9 parts of white cement and the balance of water, and stirring for 15-25 minutes to obtain the putty. The putty prepared by the method can absorb moisture in air so as to reduce the humidity during high air humidity and release moisture so as to increase the humidity during low air humidity.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of 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. 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 fre...
