Embodiment 1

[0035] This embodiment discloses a production process of an anti-myopia workbook, comprising the following steps:

[0036] (1) Prepare the following raw materials in parts by mass: 32 parts of straw, 12 parts of green sandalwood bark, 45 parts of hemp bamboo, 4.4 parts of boric acid, 8 parts of sizing agent, 4 parts of silica powder, 6.5 parts of Zhongxiang soil, 5.5 parts of wollastonite 1.5 parts of magnesium oxide, 0.04 parts of magnesium hydroxide, 1.8 parts of aluminum hydroxide, 7.5 parts of phosphoric acid;

[0037] (2) Preparation of slurry: tie the straw and soak it in water, take it out when the grass color changes from yellow to light yellow, then soak it in milk of lime, and steam it for 10 hours; take it out and wash away the residual alkali, and then make pulp by mechanical method A first slurry is obtained. Cut green sandalwood bark and hemp bamboo into wood blocks with a thickness of 0.5cm, and then soak them in 12% sodium hypochlorite solution for 6 hours; af...

Abstract

The invention belongs to the technical field of papermaking, and particularly discloses a production technology of anti-myopia workbooks. The production technology comprises the following steps: (1) preparing raw materials; (2) preparing slurry: processing straws, so as to obtain first slurry, and processing wood and bamboos so as to obtain second slurry; (3) performing mixing, and performing pulping; (4) preparing mixed liquid; (5) performing filling: mixing and stirring silicon micro powder with wollastonite, Zhongxiang earth with remained magnesium oxide so as to obtain a mixed filling, adding the mixed liquid to the mixed filling, performing stirring so as to obtain mixed materials, adding the mixed materials to pulping liquid, performing stirring, heating the liquid during stirring, and when the temperature of the liquid is heated to 78-84 DEG C, and stopping heating, so as to obtain papermaking slurry; (6) performing drying; (7) performing inking and performing printing; (8) performing binding. Through the adoption of the technical scheme of the production technology disclosed by the invention, the produced workbooks have the effect of being anti-myopia, and the obtained paper has favorable properties in aspects of strength, smoothness, printing adaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a production process of an anti-myopia workbook. Background technique [0002] Human eyes perceive fonts through the chromaticity and brightness contrast between paper and characters. White paper has a strong ability to reflect light. The whiter the paper, the stronger the reflected light. caused the greatest visual fatigue. The stronger the light, the greater the degree of visual fatigue caused. Regardless of the length of the viewing distance, the ciliary muscle is in a state of excessive contraction, causing the viewpoint to move forward. This visual environment becomes an incentive for the visual distance to approach, which can easily lead to myopia in the long run . [0003] "Anti-myopia book" can emit color light of a specific frequency, creating a safe and comfortable visual environment, which can minimize visual fatigue, give full play to the two visual ...
