Embodiment Construction

[0016] The papermaking coating provided by the present invention, the coated paper using the papermaking coating and the manufacturing method of the coated paper provided by the present invention will be further described in detail with reference to the accompanying drawings and multiple embodiments.

[0017] The invention provides a paper coating, which comprises pigment, butadiene-styrene copolymer, glucose monomer polymer, sodium polyacrylate, carboxymethyl cellulose, wet strength agent, lubricant and water.

[0018] The pigment is 100 parts by mass. The pigment is mainly calcium carbonate. The calcium carbonate includes a first type of calcium carbonate and a second type of calcium carbonate. In the first type of calcium carbonate, the content of particles with a particle size of less than 2 microns accounts for 65%. In the second type of calcium carbonate, the content of particles with a particle size of less than 2 microns accounts for 95%. In terms of mass, in 100 pa...

Abstract

A papermaking coating comprises, by weight, 100 parts of pigment, 9-12 parts of butadiene-phenylethylene copolymer, 4-6 parts of glucose monomer polymer, 0.05 part of sodium polyacrylate, 0.05-0.9 part of carboxyl methyl cellulose, and water. The solid content of the papermaking coating is 65%-71%. The invention further provides a making method of coated paper using the papermaking coating, and the coated paper.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a papermaking coating capable of providing a higher coating amount, a method for manufacturing coated paper using the papermaking coating, and coated paper. Background technique [0002] Coated paper is formed by coating at least one surface of base paper with paint mainly composed of pigments and then drying it. Coated paper can be used as commercial printing materials such as posters, brochures, advertising pictures after multi-color printing or single-color printing, or as publications such as books and magazines, and is widely used in daily work and life. [0003] The properties of coatings directly affect the performance of coated paper. An existing common coating is based on starch. When it is applied to the production of coated paper, the operability of the coating operation is poor and the coating amount is relatively low. A lower coating amount cannot provide goo...
