Abstract

The present invention provides a multi-functional environment-friendly zeolite interior wall putty powder and a preparation method thereof. The putty powder is made of the following raw materials in percentage by weight: modified zeolite powder 35-50 wt%, Shuangfei powder 30-40 wt%, ash calcium powder 3-10wt%, white cement 3-5wt%, quartz sand powder 3-5wt%, rubber powder 4-7wt%, and the rest additives. The multifunctional and environmentally friendly zeolite interior wall putty powder contains a variety of specific components, so that the product can be more firmly bonded to the concrete surface, and it will not pulverize when it meets water, and it also has a certain degree of air purification, The effect of regulating temperature and humidity.

Description

technical field [0001] The invention belongs to the field of green building materials used for indoor wall surface decoration, and in particular relates to a multifunctional environment-friendly zeolite inner wall putty. Background technique [0002] In the field of building materials, interior wall paint is a must-use material for interior wall decoration, and its usage is huge, and it is closely related to human health. While some traditional interior wall paints bring aesthetics, they may contain some harmful volatile substances such as TVOC. According to the report of the World Health Organization (WTO), a large part of 68% of modern human diseases is related to indoor air pollution. According to the data from the China Indoor Environment Monitoring Center, the number of deaths caused by indoor air pollution in my country is as high as 111,000 each year. [0003] As consumers' cognition and requirements for home decoration interior wall coatings continue to increase, t...
