Problems solved by technology

The disadvantage of this method is that it damages the physical properties of the coating
Because in order to achieve sufficient adsorption, it is necessary to ensure that the capillary pores of the porous material are exposed to the surface of the paint film, so that the paint film cannot be too dense, so its scrub resistance will be affected accordingly
Another disadvantage of the adsorption method is that when the formaldehyde content in the air is low, the adsorbed formaldehyde will be dissociated or replaced by other gases, which cannot achieve a good adsorption effect, and the adsorption capacity of the adsorption material is very limited. It is easy to reach saturation

Abstract

The invention relates to the field of fine chemical engineering, in particular to an inner wall latex paint. The inner wall latex paint comprises bamboo charcoal powder, photocatalyst, acetate-acrylic emulsion and auxiliary agents acceptable in the coating. The inner wall latex paint provided by the invention releases low formaldehyde and volatile organic compounds (VOC), and the quality of the inner wall latex paint accords with national standards; proved by experiments, the inner wall latex paint can effectively inhibit bacteria, the bacteria inhibiting rate is over 99.99 percent, and the formaldehyde removal rate is 93.05 to 97.06 percent; and the VOC removal rate of the inner wall latex paint is 52.73 to 72.11 percent, the removal rate of benzene is 53.15 to 73.26 percent, and the inner wall latex paint can constantly and effectively remove the formaldehyde and other VOC in the air.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an interior wall latex paint. Background technique [0002] Investigations by specialized agencies in the United States and Japan have found that the indoor air pollution of many civil and commercial buildings is 2 to 5 times that of outdoor air pollution. The pollution of interior decoration materials and furniture is the main cause of indoor air pollution. Among them, materials such as paint, plywood, particle filler, interior wall paint, and plastic veneer all contain organic volatiles such as formaldehyde, benzene, ethanol, and chloroform. [0003] The main components of organic volatile gases (VOC) are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, including: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters , acids and petroleum hydrocarbon compounds, etc. When the VOC in the room reac...
