The prepative method of waterborne Symphony Art Coatings

The preparation method of water-based magic color art paint consists of binder (styrene-acrylic emulsion, polyvinyl acetate emulsion), dispersant (water-based fabric dehydration slurry), pigment (iron oxide, pearl mica powder), stabilizer (aqueous solution modified paraffin wax , propylene glycol), color particle forming agent (modified polyvinyl alcohol solution), thickener (hydroxyethyl cellulose and bentonite compound), suspending agent (SH white printing paste), defoamer (tributyl phosphate) Composition, characterized in that: The preparation method of modified polyvinyl alcohol: first add 100g of PVA to 1000mL of water, heat at 90℃～94℃ for 015h to dissolve, at this time pH=6, slowly add 31% HCl 3mL, 36% formaldehyde 10mL, Adjust the pH of the liquid to 5, add 85% H3PO43mL, stir at 80°C-94°C for 1h, add 4g of urea when the liquid pH=2, stir at 80°C-90°C for 015h, cool, and adjust the pH to 7 with 10%NaOH, That is to make modified polyvinyl alcohol glue; preparation process of hydroxyethyl cellulose or sodium hydroxymethyl cellulose and bentonite composite thickener: Weigh 100g of dry bentonite, disperse it in 200g of water, stir well, remove sand Granules, add 4g Na2CO3, stir to form a slurry, then add 0.15g ~ 2g hydroxyethyl cellulose, and stir evenly to form a compound thickener colloid.
