Controlled released stably coating material capable of purifying air and preparation method thereof

Abstract

The present invention adopts special dispersion technological process and nano treatment process to make the material capable of releasing negative ions into a nano negative ion powder pulp, then adds the nano negative ion powder pulp to paint so as to obtain a long-acting stable air-purifying paint. Said paint can effectively decompose harmful gases in the air, such as formaldehyde, benzene, dimethylbenzene and nitrogen oxide, etc, and the harmful gas removing rate can be up to above 90%, and can automatically release negative ions for a long period. Its paint solid content is 20-70 wt%, and negative ion powder content is 1-10 wt%.

Description

technical field

[0001] The invention relates to the field of chemical industry, and relates to a paint capable of long-term and stable air purification and a preparation method thereof. Background technique

[0002] Negative ions refer to negatively charged ions that have obtained one or more electrons. In fountains, waterfalls, seashores, lakes and other places, the air is fresh and comfortable, because the air contains a large number of negative ions. Negative ions can not only improve air quality, but also have a The human body has a health care function——to detoxify free radicals and make body fluids weakly alkaline. It can also restore active oxygen produced by atmospheric pollutants such as nitrogen oxides and cigarettes, and neutralize positively charged air pollutants such as Dust, waste gas, virus, bacteria and other biological suspended pollutants, eliminate toxic and harmful gases such as benzene, formaldehyde, ketone, ammonia, acid odor, body odor, cigarette odor...
