| titleOfInvention | Special coating for paperboard coating and paperboard |
| abstract | The invention belongs to the technical field of coatings, and particularly relates to a special coating for coating a paperboard and the paperboard. A special paint for coating paperboard comprises a pre-coating paint, a core coating paint and a surface coating paint. The main raw materials of the coating comprise heavy calcium carbonate, kaolin, styrene-butadiene latex, coating starch, liquid alkali, water repellent agent, water-retaining agent and other additives. According to the invention, the raw material proportion is designed according to the different functions of each part of coating, kaolin with different whiteness is used for replacing part of calcium carbonate in the coating prepared by the invention, so that the coating has certain covering performance, the dosage of coating starch is higher than that of the traditional formula, which is beneficial to enhancing the strength of the coating, and the dosage of the water-retaining agent is higher than that of the traditional formula, so that the water-retaining performance of the coating can be improved, water-soluble chemical raw materials in the coating can be prevented from excessively permeating into paper, and the bonding strength between core coating and precoating coating is ensured; the invention reasonably matches each part of raw materials to ensure that the smoothness and whiteness of the coated paperboard are higher and the whole coating effect is good. |
