Abstract

The invention provides a chromo board coating. The chromo board coating comprises the following components in parts by mass: 100 parts of pigment, 0 to 30 parts of starch, 0 to 30 parts of emulsion, 0.01 to 2 parts of antifoaming agent, 0.01 to 2 parts of rheological agent, 0.01 to 2 parts of dispersing agent, 0.01 to 2 parts of bactericide, and 0.01 to 3 parts of pH (Potential of Hydrogen) modifier. According to the coating, surface sizing for raw paper is removed on the premise that the original printing intensity of a chromo board is ensured, so that the manufactured chromo board is high in density, comfortable in visual sense and smooth in touch. When in manufacturing with pulp, 20 to 30% of latching speed of a paper machine can be increased, and thus, the output is increased, and the benefit is raised.

Description

technical field [0001] The invention belongs to the field of papermaking, in particular to a coating material for papermaking and its application. 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] Copperplate cards are generally cut into flat specifications, the size is 787×1092mm, 880×1230mm, and the weight is 200-350g / square meter. The...
