Abstract

The invention relates to the field of fine chemicals, and specifically relates to an ammonia-removing and formaldehyde-removing paint. The paint comprises an orange and tangerine plant peel extract, an emulsion, titanium dioxide, heavy calcium, calcined kaolin, saponite and auxiliary agents acceptable in paints. The paint provided by the invention does not release formaldehyde, and the volatile organic compound (VOC) content of the paint is low, such that the quality of the paint satisfies a national standard. As results of experiments, the formaldehyde-removing rate is 76.49-84.97%, and the ammonia-removing rate is 100%. With the paint, formaldehyde and ammonia in the air can be effectively and continuously removed.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a coating for removing ammonia and formaldehyde. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, people's awareness of environmental protection and health requirements are increasing day by day, and the pollution caused by toxic and harmful substances in building decoration materials to the environment and the impact on human health have become increasingly prominent. Toxic and harmful substances mainly come from pollutants such as formaldehyde and ammonia released from building decoration materials. Among them, formaldehyde mainly comes from plywood, joinery board, paint, coating and other decorative materials used for interior decoration. It is a colorless and soluble irritating gas, which is relatively harmful to the human body. It can cause eye, skin, etc. It can stimulate the nervous ...
