Abstract
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 the papermaking paint field, particularly a kind of papermaking paint that good surface properties and higher paper intensity are provided, and use the coated paper of this papermaking paint.
Background technology
Coated paper carries out drying and forms after coating with pigment is the coating of main component at least one surface of body paper.Coated paper can be as commercial printed articles such as poster, brochure, advertisement posters behind polychrome printing or single color printing, or as publications such as books, magazines, thereby in routine work and life, is widely used.
The character of coating directly affects the coated paper performance.Existing a kind of common coating is to be main body with starch, and its cost is higher relatively.When being applied to coated paper production, the operability of coating operation is poor, resin added is relatively low, can not good surface properties be provided for coated paper.Another kind of lower-cost coating is to be main body with pigment, when it is used for coated paper production, can have higher resin added, but makes the coated paper intensity difference of gained.
Summary of the invention
Therefore, be necessary to provide a kind of papermaking paint that good surface properties and higher paper intensity are provided, and the coated paper that uses this papermaking paint.
A kind of papermaking paint comprises starch, pigment, binding agent, reaches water.By quality, said starch is 100 parts, and said pigment is 100 to 400 parts, and said binding agent is 0.5 to 5 part.The solid content of said 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 said body paper.Said coating layer is to form through apply papermaking paint on said body paper surface.Said papermaking paint comprises starch, pigment, reaches binding agent.By quality, said starch is 100 parts, and said pigment is 100 to 400 parts, and said binding agent is 0.5 to 5 part.The solid content of said papermaking paint is 20% to 50%, and range of viscosities is 10 to 50 centipoises.
The starch of the papermaking paint that technical scheme 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 coating operability, can adopt large high-speed paper machine to carry out applying glue easily, and does not have 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 properties and higher paper intensity simultaneously.
