Abstract

The invention relates to gypsum plaster with effects of removing formaldehyde and releasing negative oxygen ions and a preparation method of the gypsum plaster and belongs to the technical field of chemical building materials. The gypsum plaster is prepared from the following components in percentage by weight: 35%-50% of beta-semi-hydrated gypsum powder, 10%-15% of Portland cement, 5%-15% of calcium hydroxide, 10%-25% of quartz sand, 0.1%-1% of redispersible latex powder, 0.5%-2% of a water reducer, 0.1%-1% of a water retaining agent, 0.1%-1% of a defoamer, 0.1%-1% of a retarder and 12%-20% of a negative oxygen ion powder photocatalytic material. The gypsum plaster is light in weight, good in thermal insulation performance, small in shrinking percentage and fireproof, and has a breathing effect as well as functions of regulating indoor air temperature, facilitating construction and the like.

Description

technical field [0001] The invention relates to a plaster plaster capable of eliminating formaldehyde and releasing negative oxygen ions and a preparation method thereof, which belongs to the technical field of chemical building materials. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, interior decoration has become a fashion, but due to the use of building materials containing pollutants, urban indoor air pollution, especially formaldehyde pollution, is very serious. According to statistics, 60% -94% of newly decorated rooms have air formaldehyde concentration exceeding the national standard limit. [0003] Patent 101857412A discloses a multifunctional plaster ready-mixed mortar and its preparation method and application. Its formula consists of: β-hemihydrate gypsum, heavy calcium carbonate, calcium hydroxide, quartz sand, methylaminocellulose ether, adhesive , phase change material, modifi...
