Abstract

The invention provides a formaldehyde removal coating and a preparation method thereof, and relates to the field of formaldehyde treatment. The formaldehyde removal coating comprises the following components in parts by weight: 5-10 parts of an activated carbon loaded nano TiO2 material, 3-5 parts of chitosan, 3-5 parts of rosin resin, 0.1-1 part of nano graphene, 5-10 parts of lignin, 1-5 parts of a plant extract, 1-5 parts of light calcium, 0.2-2 parts of biological enzyme, 30-50 parts of silicone acrylic emulsion, 0.05-1 part of a coalescing agent, 0.05-1 part of a defoaming agent, 0.05-1 part of a dispersing agent and 20-40 parts of water, the biological enzyme comprises peroxidase, formaldehyde dehydrogenase and polyphenol oxidase, wherein the plant extract is an aloe extract, a Chinese ivy extract, an Agave americana extract and a dayflower extract. Through use of the formaldehyde removal coating, formaldehyde is removed in a manner of combining physical adsorption, chemical catalysis, the biological enzyme and the plant extracts, the removal effect is improved, and the formaldehyde removal coating is safe, non-toxic and harmless.

Description

technical field [0001] The invention relates to the technical field of formaldehyde treatment, in particular to a formaldehyde-removing coating and a preparation method thereof. Background technique [0002] Formaldehyde is the material of higher toxicity, has been determined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. Studies have shown that: formaldehyde has strong carcinogenic and short cancer effects. The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, gene mutations in the nucleus, DNA single-strand cross-linking and DNA-protein cross-linking and ...
