Problems solved by technology

However, none of the coatings sold on the market can completely solve these problems. At present, coatings are more concerned about their surface properties, such as: coatings with wet appearance, sound absorption, odor, spreading rate, water and alkali resistance, and scrub resistance. Elimination of organic compounds (VOC), formaldehyde and other harmful substances in the living environment, air purification, breathing adjustment and noise reduction, heat insulation, fire and flame retardancy, and increase the stain resistance and antibacterial ability of wall coatings are not good enough or have no effect

Abstract

The invention relates to an indoor decoration coating, in particular to a stain-resistant mould-proof diatom ooze coating and a preparation method thereof. The stain-resistant mould-proof diatom ooze coating has the advantages that with diatomite of a cellular micropore structure, zeolite powder and the like serving as functional filler, the stain-resistant mould-proof diatom ooze coating is capable of purifying harmful substances such as VOC (volatile organic compounds), formaldehyde and dampness, achieving breathing hygroscopic, heat-insulating, fireproof and flame-retarding effects, reducing noise and the like; diatomite composite nano-zinc oxide as an alkaline stabilizing agent being compounded with long-acting sterilizing mould-proof auxiliaries such as BIT isothiazolinone, methyl-1H-benzimidazol-2-yl-carbamic acid and 3-iodo-2-propynyl N-butylcarbamate, the stain-resistant mould-proof diatom ooze coating is in a weakly-alkaline state for a long term when absorbing and releasing water molecules and dampness to eradicate mould reproduction completely and therefore has the functions of mould proofing, stain resistance and self cleaning.

Description

technical field [0001] The invention relates to an interior decoration coating, in particular to a diatom mud coating and a preparation method thereof. Background technique [0002] In people's home life, problems such as wall stains, cracks, dampness, water leakage, and mold growth have long plagued our living and living, especially in the indoor environment. The concentration of harmful substances such as formaldehyde and organic compounds (VOC) frequently exceeds the standard. The mold caused by excessive air humidity reproduces rapidly, resulting in moldy and deteriorated items, causing the elderly and children with low immunity to contract diseases, which is closely related to people's health. And these problems can be solved by brushing paint. However, none of the coatings sold on the market can completely solve these problems. At present, coatings are more concerned about their surface properties, such as: coatings with wet appearance, sound absorption, odor, spreadi...
