Problems solved by technology

Traditional anti-graffiti coatings are formulated with epoxy resins; epoxy resins are very demanding on the environment. Once applied, they will form a coating similar to high-gloss glass sheets, but epoxy resins are mostly two-component, It needs to be prepared on the spot during construction, and it contains a lot of solvents, which does not meet the requirements of environmental protection

Abstract

The invention discloses a formaldehyde-removing anti-graffiti multifunctional environmentally-friendly coating comprising the following raw materials by weight: 10% to 50% of aldehyde-removing resin emulsion, 20 to 50% of anti-graffiti resin emulsion, 1 to 5% of magnesium aluminium silicate, 1 to 10% of a membrane-formation aid, 1 to 8% of ethylene urea, 0.1 to 1% of 2-amino-2-methyl-1-propanol, 1to 6% of glycerol, 3 to 9% of chitin, 0.01 to 0.5% of phenolphthalein, 0.1 to 3% of a defoamer, 0.1 to 3% of a thickener, 1 to 8% of aqueous calcium stearate, 20 to 70% of water;the sum of the abovecomponents is 100%. The preparation method comprises the following steps: adding the water, the ethylene urea, the chitin and the calcium stearate in a dispersion kettle for dispersing, further dispersing with the magnesium aluminium silicate, further dispersing with the glycerin, the defoamer and the membrane-formation aid, then adding the aldehyde-removing resin emulsion, and the anti-graffiti resin emulsion, and finally adding the thickener, the 2-amino-2-methyl-1-propanol and the phenolphthalein.

Description

technical field [0001] The invention relates to an environmentally friendly paint, in particular to a formaldehyde-removing, graffiti-resistant, multi-functional environmentally friendly paint and a preparation method thereof. Background technique [0002] Formaldehyde has been determined by the World Health Organization as a carcinogenic and teratogenic substance, and is generally considered to be the number one indoor killer. Various decorative wood-based panels inevitably contain a certain amount of formaldehyde; in newly decorated indoor environments, the incubation period of formaldehyde is as long as several years, and it is mutagenic, carcinogenic, and reproductively toxic. At present, there are many methods and tools for removing formaldehyde in the society, but the results are not satisfactory. For example, use an air purifier to purify the air and remove formaldehyde. Most of this equipment is equipped with an activated carbon adsorption layer. After a period of u...
