Problems solved by technology

However, this mode has a fatal flaw. If under the appropriate light intensity, highly active substances such as free radicals generated by photocatalysis have a strong oxidizing ability, it is likely to destroy the original core components of the coating, causing discoloration and damage to the coating. If there is no suitable light intensity, the coating will not have the purification ability, and the modified photocatalyst will also bring difficulty in adjusting the color of the coating.

Abstract

The invention discloses an environment-friendly coating for indoor air pollution risk control and a preparation method of the environment-friendly coating, and the coating comprises the following components in parts by mass (calculated as 100 parts): 30-60 parts of epoxy resin; 5 to 10 parts of titanium dioxide; 5-10 parts of negative ion powder; 2-5 parts of a formaldehyde modifier; 2-5 parts of a benzene series complexing agent; 2-5 parts of an ozone catalyst; 0.02 to 0.5 part of a dispersing agent; 0.1 to 0.5 part of leveling agent; 0.1 to 0.5 part of an antifoaming agent; 0.1 to 0.5 part of an antioxidant; 0.1 to 0.5 part of a film-forming agent; 0.1 to 1 part of an antibacterial mildew inhibitor; 5-20 parts of a curing agent; and 10 to 20 parts of deionized water; the benzene series complexing agent is a macromolecular hyperbranched polymer; and the ozone catalyst is a full-active-component high-efficiency moisture-resistant composite catalyst. The environment-friendly coating has the advantages of efficiently removing formaldehyde, ozone, benzene series and the like.

Description

technical field [0001] The invention belongs to the technical field of indoor air pollution risk management and relates to a coating, in particular to an environmentally friendly coating used for indoor air pollution risk control and a preparation method thereof. Background technique [0002] In recent years, with the rise of the home improvement industry, human beings have become increasingly polluted after the soot pollution (first generation pollution) brought about by the industrial revolution in the 18th century and the photochemical smog pollution (second pollution) brought about by the development of the petroleum and automobile industries in the 19th century. Enter the third generation air pollution period marked by indoor air pollution. Indoor pollution is recognized by the international community as the most harmful environmental factor to public health. The content of harmful gases indoors in newly renovated or newly built buildings is usually 10 to 100 times hig...
