[0004] 2. Sensitization: Skin contact with a certain dose of formaldehyde can cause allergic dermatitis; respiratory tract inhalation of a certain dose of formaldehyde may induce bronchial asthma
[0005] 3. Mutagenic effect: high concentration formaldehyde is also a genotoxic substance
The resin and some additives of traditional interior latex paint contain formaldehyde-releasing components, which will aggravate indoor formaldehyde pollution

The invention discloses a formaldehyde-reducing shell powder coating. The formaldehyde-reducing shell powder coating comprises the following components in parts by mass: water, propylene glycol, a preservative (formaldehyde-free), a dispersing agent, a defoaming agent, a wetting agent, cellulose, a pH modifier, titanium dioxide, calcined shell powder, a coalescing agent, a preservative, a formaldehyde reducing emulsion, Unihub E, a defoaming agent, a leveling agent and a rheological thickener. According to the formaldehyde-reducing shell powder, a novel formaldehyde reducing emulsion is adopted, and a grafting functional monomer is of a diketone structure which does not contain an amine or hydrazine structure, so that an odor purification effect is relatively good; two Hs of methylene between the diketone structures have relatively strong activities and easily react with formaldehyde, so that formaldehyde can be effectively purified; the formaldehyde-reducing shell powder prepared by virtue of a formula provided by the invention can meet the requirements of international standard JC / T 1074-2008 on formaldehyde purification efficiency and formaldehyde purification persistence, and furthermore, the formaldehyde purification efficiency of the formaldehyde-reducing shell powder coating reaches 85% and is high than the formaldehyde purification efficiency of most formaldehyde-reducing coatings in the market.
Description
Technical field: [0001] The invention relates to the technical field of coatings, in particular to a formaldehyde-reducing shell powder coating. Background technique: [0002] Formaldehyde is a colorless gas with a pungent smell. HCHO, C=O carbonyl group has strong reactivity and is easy to react with organic macromolecules such as proteins and nucleic acids in the body. Therefore, formaldehyde is harmful to human health. When the concentration of formaldehyde in the air exceeds a certain dose (formaldehyde exceeds the standard), it will bring harm to the human body in the following aspects: [0003] 1. Irritation effect: short-term exposure to high concentration of formaldehyde will cause irritation to the skin, mucous membranes and respiratory tract, and patients will experience symptoms such as tearing, sore throat, cough, shortness of breath, and dyspnea. [0004] 2. Sensitization: Skin contact with a certain dose of formaldehyde can cause allergic dermatitis; respirato...
