Problems solved by technology

The surface sizing agent that can be applied to watercolor painting paper is also a lot, has introduced a kind of production method of watercolor painting and calligraphy paper as Chinese patent CN107268316A, this method adopts starch to carry out surface sizing, can effectively improve the rub resistance of watercolor painting paper, but for other The improvement of several properties is small; Chinese patent CN105970716A introduces a kind of manufacturing method of handmade watercolor painting paper, this method adopts gelatin, polypropylene glue or polyethylene glue to carry out surface sizing, gelatin surface sizing can effectively improve the abrasion resistance of paper and color reproduction, but it will affect the water resistance and washing resistance of paper, while polypropylene glue and polyethylene glue are difficult to directly sizing on the surface of paper
[0004] In the prior art, the performance of each surface sizing agent is different, and the currently disclosed methods are difficult to meet all the performance requirements of watercolor painting paper at the same time

Abstract

The invention provides a surface sizing solution and a preparation method of watercolor drawing paper, and relates to the technical field of paper surface sizing. The surface sizing solution providedby the invention comprises a sizing agent and water, and the mass content of the sizing agent in the surface sizing solution is 2-8%. The sizing agent comprises the following components in parts by weight: 100 parts of gelatin; 0-10 parts of a cross-linking agent; and 0-15 parts of a water repellent agent. The content of the cross-linking agent and the content of the water repellent agent are notzero at the same time. The cross-linking agent comprises formaldehyde and / or glutaraldehyde. The water repellent agent comprises one or more of an organic fluorine compound, a styrene-acrylic emulsion, an alkylketene dimer, a paraffin emulsion and neutral rosin size. When the surface sizing solution provided by the invention is used for preparing the watercolor drawing paper, the color reducibility, the rubbing resistance, the water resistance and the washing resistance of the paper can be improved at the same time, and the performance requirements of the watercolor drawing paper are met.

Description

technical field [0001] The invention relates to the technical field of paper surface sizing, in particular to a method for preparing a surface sizing solution and watercolor paper. Background technique [0002] Painting paper is mainly divided into two categories: one is Chinese painting paper, and the other is Western painting paper. Chinese painting paper includes Xuan paper, mulberry paper and Jiajiang paper, etc. Western painting paper includes watercolor paper, oil painting paper and printmaking paper. Watercolor painting paper is a kind of high-grade painting paper specially used for drawing watercolor paintings in the art world. With the vigorous development of watercolor painting in our country, watercolor painting paper has been widely used. As the carrier of watercolor painting, the characteristics of the paper play a vital role in the realization of various techniques of watercolor painting. In order to meet the painting requirements of watercolor painting, the ...
