preparation example Construction

[0021] The preparation method of water-soluble paint for surface treatment of vacuum aluminum-coated paper base paper provided by the invention, its steps are as follows:

[0022] 1) Add the dispersant to a high-necked beaker containing 80-90% of the total weight of water, disperse and dissolve it at a speed of 200-300 rpm, add kaolin with an average particle size of 1-5 μm and a whiteness of ≥90% to the beaker, Increase the speed to 1500-2000rpm, and adjust the pH value to 7-9 to keep the physical properties of the pigment dispersion stable, disperse for 5-10 minutes, then add ordinary calcium carbonate to the beaker, keep the speed unchanged, disperse for 5-10 minutes, and finally Add nano-calcium carbonate into the beaker, increase the speed to 2000-3000rpm, and the dispersion time is 10-20min.

[0023] 2) Mix the pigment suspension, latex, thickening auxiliary latex, rheology additive, defoamer, water resistance agent and the rest of the water prepared in step 1) under rel...

Embodiment 1

[0025] 1) Add 1.5 g of sodium polyacrylate dispersant into a high-necked beaker containing 50 g of distilled water in total weight, disperse and dissolve at a speed of 300 rpm, add 80 g of kaolin to the beaker, increase the speed to 1500 rpm, and adjust the pH value to 7-9, Disperse for 10 minutes, then add 15g of ordinary calcium carbonate to the beaker, keep the speed constant, disperse for 10 minutes, and finally add 5g of nano-calcium carbonate to the beaker, increase the speed to 2500rpm, and disperse for 15 minutes.

[0026] 2) The pigment suspension prepared in step 1), 8g latex (carboxylated styrene-butadiene latex), 2g thickening auxiliary latex (CMC), 0.5g rheology modifier (organic bentonite), 1g defoamer (non-silicon defoamer) agent ZCX-02), 0.5g water-resistant agent (ZR-1 zirconium carbonate ammonium) and 17g distilled water were mixed under relatively low-speed stirring to prepare a water-soluble coating for the surface treatment of vacuum metallized paper base p...

Embodiment 2

[0028] 1) Add 1 g of sodium polyacrylate dispersant to a high-necked beaker containing a total weight of 40 g of distilled water, disperse and dissolve at a speed of 300 rpm, add 60 g of kaolin to the beaker, increase the speed to 1500 rpm, adjust the pH value to 7-9, and disperse 10min, then add 30g of ordinary calcium carbonate to the beaker, keep the speed constant, disperse for 10min, finally add 10g of nano-calcium carbonate to the beaker, increase the speed to 2500rpm, and disperse for 15min.

[0029] 2) The pigment suspension prepared in step 1), 7.5g latex (styrene-butadiene latex), 3g thickening auxiliary latex (CMC), 0.75g rheological modifier (organic bentonite), 1g defoamer (non-silicon defoamer) Agent ZCX-02), 0.5g water-resistant agent (ZR-1 zirconium carbonate ammonium) and 14g distilled water were mixed under relatively low-speed stirring to prepare a water-soluble coating for the surface treatment of vacuum metallized paper base paper, with a solid content of a...

Abstract

The invention provides water soluble paint as well as a preparation method and an application thereof. The water soluble paint for the base paper surface treatment of the vacuum aluminum-plated paper comprises a pigment, rubber latex, a dispersing agent, a rheological agent, a water-resistant agent, a defoaming agent and water, wherein the pigment is kaolin and / or calcium carbonate. The water soluble paint for the base paper surface treatment of the vacuum aluminum-plated paper can be applied to the surface treatment of cigarette lining paper. The paint for the base paper surface treatment of the vacuum aluminum-plated paper is mainly characterized in that (1) after being coated, the water soluble paint with high solid content has small drying load; (2) the defect that an organic solvent is used in the traditional paint for the surface treatment of the vacuum aluminum-plated paper is overcome, and the requirements of environmental friendliness, energy conservation and emission reduction for the paint are satisfied; (2) under the condition that a wear-resisting agent is not used, the wear resistance is better, and the cost is reduced; and (2) as a proper amount of nanometer calcium carbonate is added in the paint, the smoothness and the gloss on the surface of the paper are improved.

Description

technical field [0001] The invention relates to a water-soluble paint for surface treatment of base paper for vacuum aluminized paper, in particular to an undercoating paint for vacuum aluminized paper lining cigarettes. Background technique [0002] The main function of cigarette lining paper is to prevent moisture and maintain fragrance, including two types: calendered aluminum foil composite lining paper and vacuum aluminized lining paper. At present, calendered aluminum foil composite lining paper is widely used in the domestic tobacco industry. Its process is simple and its plasticity is strong, but the aluminum foil layer is thick (7-9μm), and the aluminum consumption is large. Composite adhesives containing volatile organic solvents such as benzene, alcohols, and ketones. In contrast, the vacuum aluminized lining paper has good processability, high brightness, thin aluminum layer (0.025-0.035μm), and is easy to degrade, and the vacuum aluminized lining paper using wa...
