Environmentally friendly water-based paint capable of removing formaldehyde through reacting and preparation method thereof

Abstract

An environmentally friendly water-based paint capable of removing formaldehyde through reacting comprises 1 to 10 weight parts of ethylideneimine ketone, 30 to 45 weight parts of polymer emulsion, 0.5 to 2.0 weight parts of a film forming additive, 0.1 to 0.5 weight parts of an antifoaming agent, 20 to 40 weight parts of filling materials, 15 to 30 weight parts of distilled water and 2 to 5 parts of other additives. The preparation method of the environmentally friendly water-based paint comprises successively adding a wetting agent, a dispersant, parts of the antifoaming agent and the filling materials into the distilled water and then grinding to disperse to get slurry ; preparing a 30 % ethylideneimine ketone solution which is then added into the polymer emulsion; and successively adding the slurry, the film forming additive, the remaining antifoaming agent, a mildew preventor, an antifreeze, a levelling agent and a thickening agent into the polymer emulsion, adjusting a PH value to 8.0 to 9.5, and finally carrying out constant volume operation with the distilled water. The paint can effectively inhibit release of the formaldehyde in water-based paints, and has advantages of low production cost, simple process and suitability for popularizing.

Description

【Technical field】 [0001] The invention relates to an environment-friendly water-based paint with the function of removing formaldehyde by reaction, and a preparation method of the environment-friendly water-based paint. 【Background technique】 [0002] In recent years, people have paid more and more attention to the problem of home decoration pollution, and for most families, the most important substance of indoor pollution is formaldehyde. The formaldehyde that causes home decoration pollution comes from various decoration materials. Specifically, the formaldehyde in decoration pollution mainly comes from the adhesives used in wood-based panels and furniture, as well as the paint sprayed on interior walls and furniture surfaces. Formaldehyde can be released slowly due to the use of urea-formaldehyde or phenolic resin adhesives with formaldehyde as the main component in the production of various artificial boards and some furniture, and in the decoration of walls and floors. ...

AI Technical Summary

Problems solved by technology

In addition, water-based paint represented by latex paint, as a substitute for organic solvent-based paint, its dispersion medium is water, which has less environmental pollution. There are more or less formaldehyde residues, so the wall paint will still release formaldehyde and other harmful substances into the air during use, resulting in serious indoor air pollution.
