The invention discloses papermaking paint. The papermaking paint comprises starch, a pigment, a binder and water. Calculated based on mass, the starch takes up 100 parts, the pigment takes up 100-400 parts and the binder takes up 0.5-5 parts. The solid content of the papermaking paint is 20% to 50%, and the viscosity range is from 10 to 50 centipoises. The technical scheme also provides coated paper using the papermaking paint.
Description
Technical field
The invention belongs to papermaking paint field, particularly a kind of papermaking paint that good surface property and higher paper intensity are provided, and use the coated paper of this papermaking paint.
Background technology
Coated paper be coated with on the surface at least one of body paper with pigment be main component coating after carry out drying and formed.Coated paper can as commercial print things such as poster, brochure, advertisement posters after polychrome printing or single color printing, or as the publication such as books, magazine, thus be widely used in routine work and life.
The character of coating directly affects ways and methods.Existing a kind of common coating is based on starch, and its cost is relatively high.When being applied to coated paper production, the operability of coating operations is poor, resin added is relatively low, can not provide good surface property for coated paper.Another kind of lower-cost coating is based on pigment, when it is produced for coated paper, can have higher resin added, but make the coated paper intensity difference of gained.
Summary of the invention
Therefore, be necessary to provide a kind of papermaking paint that good surface property and higher paper intensity are provided, and use the coated paper of this papermaking paint.
A kind of papermaking paint, comprises starch, pigment, binding agent and water.By mass, described starch is 100 parts, and described pigment is 100 to 400 parts, and described binding agent is 0.5 to 5 part.The solid content of described papermaking paint is 20% to 50%, and range of viscosities is 10 to 50 centipoises.
A kind of coated paper, comprises body paper and covers the coating layer of described body paper.Described coating layer is formed by applying papermaking paint on described body paper surface.Described papermaking paint comprises starch, pigment and binding agent.By mass, described starch is 100 parts, and described pigment is 100 to 400 parts, and described binding agent is 0.5 to 5 part.The solid content of described papermaking paint is 20% to 50%, and range of viscosities is 10 to 50 centipoises.
The starch of the papermaking paint that technical solution of the present invention provides and pigment have specific ratio, and its solid content and viscosity are also in a particular range.This papermaking paint has good painting work, and large high-speed paper machine can be adopted easily to carry out applying glue, and without the generation of stuck glue, the unequal bad phenomenon of applying glue during applying glue.Use the coated paper of this papermaking paint to possess good surface property and higher paper intensity simultaneously.
