▎ 摘 要
NOVELTY - An anti-corrosion coating comprises raw materials comprising 40-50 pts. wt. modified acrylic emulsion, 0.8-1 pt. wt. modified graphene, 9-13 pts. wt. titanium dioxide, 8-10 pts. wt. talc powder, 1.2-1.6 pts. wt. anti-rust additives, 5-6 pts. wt. additive agent, and 20-30 pts. wt. deionized water. The coating is prepared by adding modified graphene, titanium dioxide and talc powder to the modified acrylic emulsion, increasing temperature to 80-90 degrees C, dispersing at high speed of 800-1000 rpm under constant temperature of 25-30 minutes to obtain a premix, and stopping heating, adding additive thickening agent, dispersant and coupling agent to 1/3 volume of deionized water, stirring, mixing evenly and adding to the obtained premix, dispersing for 10-12 minutes at 400-500 rpm, adding anti-rust additives, and dispersing for 8-10 minutes, and adding film-forming additive agent, defoaming agent, and remaining deionized water and dispersing at 200-300 rpm for 15-17 minutes. USE - Anti-corrosion coating used as shielding layer for protecting metal-made building materials. ADVANTAGE - The coating has excellent corrosion resistance, film-forming performance, adhesiveness with respect to substrate, water resistance and aging resistance by using modified acrylic emulsion, comprehensive properties, and can slow down the contact between building materials and corrosive media, by using modified graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of anti-corrosion coating, which involves adding modified graphene, titanium dioxide and talc powder to the modified acrylic emulsion, increasing the temperature to 80-90 degrees C, dispersing at high speed of 800-1000 rpm under constant temperature for 25-30 minutes to obtain a premix, and stopping heating, (ii) adding additive thickening agent, dispersant and coupling agent to 1/3 volume of deionized water, stirring and mixing evenly and adding to the obtained premix, dispersing for 10-12 minutes at 400-500 rpm, then adding anti-rust additives, and dispersing for 8-10 minutes, and (iii) adding film-forming additive agent and the defoaming agent, and remaining deionized water and dispersing at 200-300 rpm for 15-17 minutes.
