High-whiteness chromo board paint and high-whiteness chromo board

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.
