specific Embodiment approach

[0012] The specific embodiment: below is an example of the present invention:

[0013] The composition and weight ratio of a water-based anti-acid and alkali digital imaging paint are as follows: 18 parts of water, 22 parts of elastic emulsion, 20 parts of fluorocarbon emulsion, 1.5 parts of wetting agent, and 0.8 parts of dispersing agent are added sequentially at low speed; 4 parts of titanium dioxide BA0101; 8 parts of nano-silicon dioxide; 7 parts of opaque polymer OP-62B added in sequence at medium speed; 16 parts of light calcium carbonate; 0.2 parts of dispersant polyvinylpyrrolidone S-1, Then carry out high-speed dispersion for 30 minutes, 0.45 parts of defoamer 224, 0.05 parts of film-forming aid; 2 parts of cationic color-fixing agent polyacrylate ammonium salt, measure viscosity and pH value, weigh and pack.

[0014] According to experiments and customer use, the water-based acid and alkali resistant digital image coating of the present invention has good ink-fixing...

Abstract

The invention discloses an aqueous acid-and-alkali-resistant digital imaging coating. The aqueous acid-and-alkali-resistant digital imaging coating comprises 10-20wt% of water, 20-22wt% of an elastic emulsion, 20-25wt% of a fluorocarbon emulsion, 0.8-1.6wt% of a wetting agent, 0.7-0.9wt% of a dispersant, 3-5wt% of titanium dioxide, 7-9wt% of nanometer silica, 6-8wt% of an opaque polymer, 16-18wt% of light calcium carbonate, 0.05-0.7wt% of an antifoaming agent, 0.05-0.1wt% of a film forming assistant and 1-3% of a cationic color fixing agent. A film obtained through using the coating has the advantages of good ink fixing performance, good water resistance, unlikely color change and dye penetration, strong acid and alkali resistances, low softness, good elasticity, and suitable smoothness and glossiness.
