Abstract

The invention relates to a method for preparing a light resistant and antiflaming aqueous acrylate resin coating. The method is characterized by comprising the steps of heating up water, an emulgator, tea polyphenol lipidosome and methacrylic acid to be 55DEG C, stirring for 90 minutes, adding polyaniline, nano zirconia, monomer A, an antiflaming material and estradiol benzoate, emulsifying for 40-60 minutes, heating up to 80DEG C, keeping warm for 1 hour, dropwise adding an initiator, then reacting for 2 hours so as to obtain nuclear layer emulsion; and dropwise adding monomer B and an initiator into the nuclear layer emulsion simultaneously, keeping warm and reacting for 2 hours, adding a fermenting material C, keeping warm at 75-85DEG C and reacting for 1-3 hours, adding metal salt, regulating pH to be 4.0, keeping warm at 75-85DEG C and reacting for 1-2 hours, cooling to be 50DEG C, adding a crosslinking agent, reacting for 30 minutes, adding ammonia water to regulate pH value to be 5, adding bronopol, regulating the temperature to be 75-85DEG C, reacting for 30 minutes, so as to obtain the light resistant and antiflaming aqueous acrylate resin coating. The obtained acrylate resin coating has good light resistance and fire resistance, and has environment-friendly production technology.

Description

technical field [0001] The invention relates to a method for preparing a coating, in particular to a method for preparing a light-resistant and flame-retardant water-based acrylic resin coating. Background technique [0002] Acrylic emulsion paint is the most widely used type of emulsion paint. It can be used not only as interior and exterior wall paint and roof waterproofing materials in the construction industry, but also as a fabric coating agent in the textile industry and as a fabric coating agent in the leather industry. Leather finishing agent, but also can be applied to metal, wood coatings, road marking coatings, paper and textile adhesives, etc. However, due to the fact that the field of use is often exposed to sunlight, since the sun’s rays contain a large amount of ultraviolet light harmful to colored objects, its wavelength is about 290~460nm, these harmful ultraviolet light will change the color of the coating through chemical oxidation and reduction. , affect...
