Abstract

An energy-saving water-based coating adsorbing and degrading formaldehyde and releasing negative oxygen ions is characterized in that the energy-saving water-based coating is prepared from, by weight, at least 15-30 parts of hydroxyl water-based resin, 40-100 parts of a first packing and 5-25 parts of a second packing, wherein the first packing is one or more of diatomite, coarse whiting and ash calcium, and the second packing is selected from montmorillonite and / or sericite. The energy-saving water-based coating has good breathability, water resistance, formaldehyde degradation performance and other excellent performance and can be used on the basic layers and face layers of building walls.

Description

technical field [0001] The invention relates to an energy-saving water-based paint which absorbs and degrades formaldehyde and releases negative oxygen ions. Specifically, the present invention relates to an energy-saving water-based coating that absorbs and degrades formaldehyde and releases negative oxygen ions and a preparation method thereof. More specifically, the present invention relates to an energy-saving water-based coating that absorbs and degrades formaldehyde and releases negative oxygen ions, as well as its preparation method and construction process. Background technique [0002] With the improvement of living standards, the problem of indoor air pollution is gradually attracting people's attention. Studies have shown that volatile harmful gases released by interior decoration and decoration materials such as formaldehyde, benzene, and toluene are the main causes of air pollution. Existing interior wall paints often add glue, latex powder, varnish and other ...
