Embodiment 1

[0030] Embodiment 1 The raw materials of the high-whiteness copper plate card coating are as follows: heavy calcium carbonate 100g, fatty acid antifoaming agent 0.02g, ethylene-based bis-stearamide 0.02g, acrylic resin 0.2g, styrene-butadiene latex 5g, Modified corn starch 8g, processed potato starch 1g, stilbene 0.5g, isothiazolinone 0.02g, sodium hydroxide 0.15g. Adding 0.15 g of sodium hydroxide in Example 1 can make the pH of the coating 8.5-9.

Embodiment 2- Embodiment 4

[0032] Embodiment 2-Example 4 differs from Example 1 only in that the amount of whitening agent and thickener in the high-whiteness copperplate card coating is different, and the raw materials used in Example 1-Example 4 high-whiteness copperplate card coating As shown in Table 1, adding 0.15g of sodium hydroxide in Examples 2-4 can make the pH of the coating be 8.5-9.

Abstract

The invention relates to the papermaking field, and especially relates to a high-whiteness chromo board paint and a high-whiteness chromo board. The high-whiteness chromo board paint comprises the following raw materials by mass fraction: 100 parts of pigment, 4-6 parts of synthetic latex, 8-10 parts of biological latex, 0.01-0.05 parts of antifoaming agent, 0.1-0.3 parts of rheological agent, 0.01-0.05 parts of dispersant, 1-5 parts of thickener, 0.5-1.5 parts of brightening agent, 0.01-0.05 parts of bactericide and a proper amount of pH conditioning agent. The chromo board paint is used for double face coating on a copperplate raw paper, and then infrared drying, drying in a baking oven and rewinding steps are carried out to obtain the high-whiteness chromo board. The high-whiteness chromo board has the printing effects that the paper glossiness is especially excellent, ink color is bright, the paper is highwhite, loose thickness is high, roughness is high, stiffness is excellent, the hand feeling is concave-convex, the paper color is light, and the high-whiteness chromo board is rich in artistic atmosphere.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a high-whiteness copperplate card coating and a high-whiteness copperplate card. Background technique [0002] Art Board is a high-grade printing cardboard made of base paper coated with white paint, with a weight of more than 200gsm. It is mainly used for printing the cover of high-grade books and periodicals, color pictures, various exquisite commodity advertisements, samples, commodity packaging, trademarks, etc. Art Board was translated as art card in my country in the 1930s. Because when this kind of paper was used to print exquisite famous paintings in Europe, the printing plate corroded by the copper plate was used for drying, so according to the convention of naming by purpose, the art paper used for copper plate printing is called copper plate card. [0003] The main raw materials of copperplate cards are copperplate base paper and paint. The requirements for coated base pa...
