Embodiment 1

[0028] 1) Preparation of topcoat

[0029] 100g of calcium carbonate, 0.06g of sodium polyacrylate were mixed and dispersed at high speed for 30min. After the dispersion was uniform, 11g of styrene-butadiene latex, 0.01g of fatty acid antifoaming agent, 0.08g of sodium carboxymethyl cellulose, and 0.12g of sodium hydroxide were added. .

[0030] 2) Preparation of primer

[0031] Primer coating ratio: calcium carbonate 100g, styrene-butadiene latex 11g, fatty acid antifoaming agent 0.01g, sodium hexametaphosphate 0.04g, polyamide 0.08g, sodium hydroxide 0.12g.

[0032] The coating weight of the primer is 10-20g, and the coating weight of the topcoat is 10-20g. The primer is applied first and then the topcoat is applied. After coating, it is dried and calendered with a super calender to ensure bulk and smoothness. , the characteristics of gloss.

[0036] 2) Preparation of primer

[0037] Primer coating ratio: calcium carbonate 100g, styrene-butadiene latex 11g, fatty acid antifoaming agent 0.01g, sodium hexametaphosphate 0.04g, organic bentonite 0.08g, sodium hydroxide 0.12g.

[0038] The coating weight of the primer is 10-20g, and the coating weight of the topcoat is 10-20g. The primer is applied first and then the topcoat is applied. After coating, it is dried and calendered with a super calender to ensure bulk and smoothness. , the characteristics of gloss.

Embodiment 3

[0040] 1) Preparation of topcoat

[0041] 100g of calcium carbonate, 0.06g of sodium polyacrylate were mixed and dispersed at high speed for 30min. After the dispersion was uniform, 11g of styrene-butadiene latex, 0.01g of fatty acid antifoaming agent, 0.08g of sodium carboxymethyl cellulose, and 0.12g of sodium hydroxide were added. .

[0042] 2) Preparation of primer

[0043] Primer coating ratio: calcium carbonate 100g, styrene-butadiene latex 11g, fatty acid antifoaming agent 0.01g, sodium hexametaphosphate 0.04g, polyvinyl alcohol 0.08g, sodium hydroxide 0.12g.

[0044] The coating weight of the primer is 10-20g, and the coating weight of the topcoat is 10-20g. The primer is applied first and then the topcoat is applied. After coating, it is dried and calendered with a super calender to ensure bulk and smoothness. , the characteristics of gloss.

Abstract

The invention provides a coated paper coating with high printing gloss. The coated paper coating comprises topcoat and first coat. The invention further provides a preparation method of the coated paper coating with high printing gloss. The gloss difference change of coated paper is large before and after the coated paper is printed, the gloss difference between the printed coated paper and the coated paper which is not printed is effectively increased, the printing stock content to be shown is highlighted, the printing effect is remarkably improved, the printing quality of the coated paper is improved, on-machine running performance can be improved, and the quality of the coated paper can be improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a high printing gloss coated paper coating and a preparation method thereof. Background technique [0002] Coated paper is widely used as a kind of cultural paper, and commercial printing has a great demand for coated paper with good gloss after printing. For the coated paper with high gloss before printing, the gloss difference before and after printing is also crucial to the printing quality. At present, the coated paper on the market mainly relies on improving the pre-press gloss to correspondingly improve the post-press gloss, and the resulting difference in gloss before and after printing is small, which cannot highlight the content of the substrate to be displayed, which has a certain impact on the printing effect. . SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a coating for coated paper with high p...
