Abstract

The invention discloses environment-friendly architectural paint capable of absorbing formaldehyde. The architectural paint comprises the following raw materials in parts by weight: 10-25 parts of a citrus peel extract, 10-25 parts of diatomite, 35-50 parts of a formaldehyde-removing styrene-acrylic emulsion, 5-20 parts of quartz sand, 15-35 parts of coarse whiting, 0.1-1 part of hydroxyethyl cellulose, 1-10 parts of calcined kaolinite, 0.3-1.5 parts of one or two dispersing agents, 0.1-1 part of an antifoaming agent, 0.1-1.2 parts of a thickening agent, 0.1-0.5 parts of a wetting agent and 80-100 parts of deionized water. The architectural paint can acheive the function of removing formaldehyde without being subsequently added with a functional material, so that the long-term effect and the stability on formaldehyde removing of the architectural paint are achieved; both the purification efficiency and the purification effect of the architectural paint reach the standards, wherein the purification efficiency is higher than 85% and the purification persistence index is higher than 70%.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a formaldehyde-absorbing environment-friendly architectural coating and a preparation method thereof. Background technique [0002] Formaldehyde, as one of the toxic and harmful substances produced by interior decoration materials, seriously affects the health of human households. 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. [0003] CN104046062A discloses a formaldehyde-absorbing architectural coating. The coating produces hydr...
