▎ 摘  要

NOVELTY - Natural non-toxic aqueous paint comprises 35-45 wt.% water-soluble resin, 17-23 wt.% filler, 13-17 wt.% adjuvant and 20-30 wt.% deionized water. USE - Used as natural non-toxic aqueous paint. ADVANTAGE - The natural non-toxic aqueous paint: utilizes silicon carbide fiber and graphene oxide which reduces sedimentation of fillers during curing process of the paint, improves toughness and strength of paint to avoid cracking and peeling; utilizes nano titanium dioxide and aluminum oxide powder which improves antibacterial effect and anti-ultraviolet ability of paint. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing natural non-toxic aqueous paint comprising (i) adding ceramic microbeads, silicon carbide fibers, nano-titanium dioxide and alumina powder into the mixer, stirring at 300 revolution/minute for 20 minutes to obtain filler, (ii) adding anti-settling agent, cyclohexanone into reaction kettle, heating to 40-50degrees Celsius, then adding polyamide wax, ultrasonically dispersing for 40-60 minutes, reducing temperature of the mixed reactants to normal temperature, then adding zinc stearate and liquid paraffin into cooled mixed reactants, ultrasonically dispersing for 30-50 minutes to obtain anti-settling agent, (iii) adding deionized water and water-soluble resin into reaction kettle, fully stirring for 20-30 minutes, adding anti-settling agent, preservatives, film-forming aids, dispersants, defoaming agent and toughening agent, fully stirring for 20-30 minutes, adding the filler into obtained solution, fully stirring for 30-50 minutes to obtain semifinished paint and (iv) transferring semifinished paint to sand mill for repeated grinding, and then filtering to obtain final product.
