Embodiment 1

[0021] The raw rice paper is lightly calendered once with a calender at a speed of 1000m / min, a pressure of 40KN / m, and a temperature of 50°C. Then, 80 parts by mass of enzyme-converted starch, 10 parts by mass of polyvinyl alcohol, and AZC type water-resistant The sizing solution combined with 10 parts by mass of chemical agent is sizing once on each side with a concentration of 11% at 50°C, and dried by an infrared dryer. Repeat the above actions and coat each side once. , the total coating amount per side is 6g / m 2 , Obtain the rice paper for printing.

Embodiment 2

[0023] The cooked rice paper is sizing solution composed of 95 parts by mass of enzyme-converted starch and 5 parts by mass of PAPU type water-resistant agent, using a roller coater at a concentration of 8% and a temperature of 50°C to carry out sizing on each side once, and using infrared rays Dry in the dryer, repeat the above actions and apply twice on each side, the amount of coating on each side is 7g / m 2 , Obtain the rice paper for printing.

Embodiment 3

[0025] Cooked rice paper adopts 85 parts by mass of etherified starch, 10 parts by mass of PAPU type water-resistant agent, and 5 parts by mass of carboxymethyl starch. The sizing solution combined with a concentration of 8% at a temperature of 60 ° C uses a roll coater to carry out sizing on each side Once, and use an infrared dryer to dry, repeat the above action and coat each side again, the total coating amount of each side is 6g / m 2 , the paper of gained adopts calender to carry out light calendering once with the speed of 1000m / min, the pressure of 40KN / m, the temperature of 50 ℃, obtain described rice paper for printing.

Abstract

The invention discloses printing rice paper and a manufacture method thereof. The printing rice paper comprises a rice paper body, wherein a surface gluing layer is arranged on the rice paper body; and the surface gluing layer comprises the following components: 75-100 parts by mass of starch, 20-0 parts by mass of polyvinyl alcohol, 25-0 parts by mass of hydrated resistant agent and 20-0 parts bymass of carboxymethocel or carboxymethyl starch. The traditional rice paper is processed by the processes of surface gluing, calendaring, and the like during the manufacture to be manufactured a ricepaper product suitable for modern printing. The printing rice paper product maintains the original pure vein of the rice paper and has the characteristics of smooth performance and loose and tough quality. By adopting the printing rice paper to print, no hair falling phenomenon generates, and the printing speed and the production efficiency are high.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to processing traditional rice paper by surface sizing, calendering and other processes to produce printing rice paper suitable for modern printing and a manufacturing method thereof. Background technique [0002] Xuan paper is a treasure of Chinese culture. It can be divided into cooked rice paper and raw rice paper. The characteristic of cooked rice paper is that it does not infiltrate after contact with water, while raw rice paper has a strong wetting property when it encounters water. Two kinds of rice paper are used to make traditional Chinese paintings, that is, ink and water-soluble pigments are used to paint on rice paper, which has a better effect. However, there are many shortcomings in printing. On the one hand, due to the rough surface, it is impossible to show the realism of the printed product; Frequent parking, low production efficiency. [0003] Along with t...
