Abstract

The invention relates to building coating capable of removing methyl aldehyde and a preparation method of the building coating. The building coating capable of removing methyl aldehyde is prepared from the following components in parts by weight: 20-30 parts of deionized water, 0.1-0.5 part of hydroxyethyl cellulose, 0.1-0.2 part of a pH regulator, 0.5-1.2 parts of a dispersing agent, 0.2-0.4 part of a lubricating agent, 0.2-0.6 part of a defoaming agent, 10-20 parts of titanium dioxide, 20-30 parts of calcium triple superphosphate, 1-5 parts of calcined kaolin, 1-5 parts of diatomite, 0.1-0.5 part of a thickening agent, 30-40 parts of aldehyde removal styrene-acrylic emulsion, 2-3 parts of a coalescing agent and 0.5-1.5 parts of propylene glycol. The prepared building coating capable of removing the methyl aldehyde has the advantage that an aldehyde removal function can be realized without adding a functional material later, and long-term and stable aldehyde removal effect of the prepared building coating is realized.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a formaldehyde-removable architectural coating and a preparation method thereof. Background technique [0002] Formaldehyde is the main toxic and harmful substance produced by interior decoration materials, which seriously affects the health of human household. Reports have shown that long-term exposure to formaldehyde can cause various respiratory tract, digestive tract and skin cancers. At present, people usually use indoor ventilation, prolong the stay time, and use formaldehyde remover to reduce the indoor formaldehyde concentration. The above method is difficult to remove the formaldehyde release point in the concealed and unventilated area. In order to effectively remove formaldehyde from interior decoration for a long time, people have done a lot of work. CN101020794B has introduced a kind of preparation method of environment-friendly water-based paint, mainly uses amino compoun...
