Embodiment 1

[0039] Step 1, beating: 100% bleached cotton pulp (whiteness not less than 80 degrees). The raw materials are added to a 300-liter beater for beating, and the beating time is about 1 hour until the fibers of the raw materials are completely dispersed;

[0040] Step 2. In-pulp sizing: After the beating is completed, first lift the beating knife roller of the beating machine, and then add neutral sizing agent AKD with a dry weight of 0.1% of the raw material to the beating machine that has been beaten. Make it disperse evenly for about five minutes; then add wet strength agent PAE of 0.1% dry weight of the raw material to the beater, and run the knife for about five minutes to make it evenly dispersed to form pulp;

[0041] Step 3: Pour the pulp into a 1.2-meter-long, 1.2-meter-wide, and 1-meter-deep stainless steel papermaking tank, and add water until the slurry concentration is 2‰ (the weight percentage of absolute dry fiber to water), and carry out after fully mixing. fish ...

Embodiment 2

[0050] Step 1, beating: add 100% bleached hemp pulp (whiteness not less than 80 degrees) raw materials into a 300-liter beating machine for beating, and the beating time is about 1 hour until the fibers of the raw materials are completely dispersed;

[0051] Step 2. In-pulp sizing: After beating, first lift the beating knife roller of the beater, and then add neutral sizing agent AKD with a dry mass of 0.2% of the raw material to the beater that has been beaten. Make it disperse evenly for about five minutes; then add wet strength agent PAE with 0.2% absolute dry mass of raw materials into the beater, and run the knife for about five minutes to make it disperse evenly to form pulp;

[0052] Step 3: Pour the pulp into a stainless steel tank with a length of 1.2 meters, a width of 1.2 meters, and a depth of 1 meter, and add water until the concentration of the pulp is 2‰, mix well and then fish out the paper;

Embodiment 3

[0061] Step 1, beating: Add half of the bleached cotton pulp and half of the bleached hemp pulp into a 300-liter beater for beating. The beating time is about 1 hour until the fibers of the raw materials are completely dispersed;

[0062] Step 2. In-pulp sizing: After the beating is completed, first lift the beating knife roller of the beater, and then add neutral sizing agent AKD with a dry weight of 0.3% of the raw material to the beater that has been beaten, and move the knife Make it disperse evenly for about five minutes; then add wet strength agent PAE with 0.3% absolute dry mass of the raw material into the beater, and run the knife for about five minutes to make it disperse evenly to form pulp;

[0063] Step 3: Pour the pulp into a stainless steel tank with a length of 1.2 meters, a width of 1.2 meters, and a depth of 1 meter, and add water until the concentration of the pulp is 2‰, mix well and then fish out the paper;

Abstract

The invention belongs to the technical field of papermaking, and discloses a method for making manual watercolour paper. The method comprises the following steps that 1, pulping is carried out; 2, gluing in pulp is carried out; 3, the pulp is poured into a container, water is added, and the mixture is fully mixed to be uniform; 4, paper fishing is carried out; 5, wet paper squeezing is carried out; 6, vacuum water absorption is carried out; 7, double rollers are used for embossing; 8, drying is carried out through a drying cylinder; 9, surface gluing is carried out, wherein the surface of dried finished paper is coated with gelatin or polypropylene glue or polypropylene glue, and natural drying is carried out. The manual watercolour paper good in drawing performance, high in ageing resistance and capable of meeting the individual needs of painters is obtained.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a method for manufacturing handmade watercolor painting paper. Background technique [0002] Watercolor paper is art paper specially designed for drawing watercolor paintings. Watercolor painting is Western painting. Generally, the picture drawn with water and pigment is called watercolor painting. Its painting method has two kinds of dry method and wet method.
