Abstract

The invention discloses an inorganic aldehyde-removing fireproof water-based coating, which comprises the following components in parts by weight: 62-75 parts of water-based epoxy-modified acrylic resin, 6-18 parts of inorganic aldehyde-removing modifier, and 5 parts of flame retardant ~10 parts, 0.1~0.5 parts of wetting and dispersing agent, 0.1~0.3 parts of coalescent agent, 0.05~0.2 parts of defoaming agent and 15~30 parts of deionized water. The water-based epoxy-modified acrylic resin used in the present invention is green and environmentally friendly. After adding flame retardants, inorganic aldehyde-removing modifiers and various additives, the coating is not only environmentally friendly, but also has strong flame retardancy. In addition, it can remove harmful gases such as formaldehyde emitted by other materials, so it has a good formaldehyde purification effect.

Description

Technical field [0001] The present invention relates to the field of environmentally friendly coatings, specifically to an inorganic aldehyde removal fire-retardant waterborne coating. Background [0002] With the continuous improvement of people's living standards in recent years, interior decoration materials are becoming more and more abundant, and some materials will gradually release toxic and harmful substances such as formaldehyde during use. Formaldehyde pollutants mainly come from decorative materials such as plywood, fine wood panels, paints and coatings used as interior decoration, which is a colorless and soluble irritating gas, which is more harmful to the human body, it can cause irritation of the eyes, skin and respiratory tract, causing abnormal function of the nervous system, immune system, endocrine system, and at the same time has embryotoxicity, teratogenic effect, carcinogenic effect, and the flame retardant effect of existing building decoration materials is...
