Embodiment 1

[0037] Example 1: A formaldehyde-removing coating, which includes components and their corresponding parts by weight as shown in Table 1, and is prepared through the following steps:

[0038] S1: Add corresponding weight parts of mesoporous silicon and catalytic titanium dioxide into the paint stirring tank, and stir the mesoporous silicon and catalytic titanium dioxide evenly at a speed of 500 rpm;

[0039] S2: Add corresponding parts by weight of water-soluble hydroxyethyl cellulose, defoamer, silicone-based regulator and other components by corresponding parts by weight and stir at a speed of 500 rpm for ten minutes;

[0040] S3: Add toning titanium dioxide for toning, diatomaceous earth and heavy calcium carbonate and stir at a speed of 1250 rpm for 30 minutes;

[0041] S4: Add the anti-freeze-thaw stabilizer and defoamer of corresponding weight parts and stir at a speed of 1000 rpm for five minutes, and observe the elimination of bubbles during the stirring process;

Abstract

The invention discloses a formaldehyde-removing coating and a preparation method thereof. The coating is prepared from the following components in parts by weight: 18.35 to 21.25 parts of deionized water, 8.3 to 12.5 parts of calcium carbonate, 15.3 to 30.6 parts of diatomite, 10.1 to 20.4 parts of toned titanium dioxide, 0.8 to 1.2 parts of an anti-freezing and thawing stabilizer, 0.2 to 0.6 partof a defoaming agent, 0.08 to 0.4 part of a silicone matrix conditioner, 0.9 to 4.5 parts of rheology modifier, 25.1 to 36.6 parts of special emulsion for self-crosslinking and 0.8 to 1.9 parts of rest components; the special emulsion for self-crosslinking is prepared from pure acrylic acid and a reactant for reacting with formaldehyde, wherein the mixing weight ratio of the pure acrylic acid tothe reactant is (2.72 to 3.92) : 1; the rest components include a dispersing agent, a wetting agent and a bactericide. The formaldehyde-removing coating disclosed by the invention has an effect of effectively absorbing and decomposing formaldehyde.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a formaldehyde-removing coating and a preparation method thereof. Background technique [0002] There are often a large amount of harmful substances such as formaldehyde in newly renovated rooms. Formaldehyde will cause great damage to the human body and need to be vacant for a long time before moving in. The formaldehyde-removing paints currently on the market can only absorb formaldehyde in the paint on the wall without actually decomposing formaldehyde. [0003] At present, the Chinese patent document with the application publication number CN105086650A in the prior art discloses an environmentally friendly architectural coating that absorbs formaldehyde, which includes the following raw materials by weight fraction: 10-25 parts of citrus fruit peel extract, 10-25 parts of diatomaceous earth , 35-50 parts of aldehyde-removing styrene-acrylic emulsion, 5-20 pa...
