Abstract

The invention belongs to the technical field of papermaking, and concretely discloses drawing paper. The drawing paper comprises the following raw materials, by weight: 30-40 parts of softwood pulp, 30-40 parts of hardwood pulp, 20-40 parts of mechanical pulp, 10-15 parts of poplar pulp, 1-5 parts of cationic starch, and 2-4 parts of surface glue.

Description

technical field [0001] The application belongs to the technical field of papermaking, in particular to a production process of drawing paper. Background technique [0002] Drawing paper is drawing paper for watercolors, pencil drawings, charcoal drawings, etc. The paper is white and thick, with irregular lines on the paper surface. It is resistant to friction, so that it is not easy to fluff when rubbing with an eraser when painting. And it has good water resistance, so that it will not spread when painting watercolors. [0003] The traditional production method of drawing paper has strict requirements on pulp, most of which use bleached wood pulp and cotton pulp as raw materials, and the production cost is high. Contents of the invention [0004] In order to solve the above technical problems, the application provides a drawing paper production process, the application is achieved by the following scheme: [0005] A drawing paper, comprising the following raw material...
