Embodiment 1

[0031] This embodiment discloses a production process of anti-myopia paper, comprising the following steps:

[0032] (1) Prepare the following raw materials in mass parts: 29 parts of rice straw, 16 parts of reed, 12 parts of mulberry bark, 38 parts of Cizhu, 4.2 parts of boric acid, 8 parts of sizing agent, 3.6 parts of silicon micropowder, 5.3 parts of talcum powder, 6 parts of earth, 0.12 parts of magnesium oxide, 0.02 parts of magnesium hydroxide, 1.5 parts of aluminum hydroxide, and 7.5 parts of phosphoric acid.

[0033](2) Preparation of slurry: select the stalks of straw and reed, tie them into water and soak them in water, take them out when the grass color changes from yellow to light yellow, then soak them in milk of lime, and steam them for 10 hours; take them out and wash away the residual alkali, then The first slurry is obtained by mechanical pulping. Cut mulberry bark and Cizhu into wood blocks with a thickness of 0.45 cm, and then soak them in 10% sodium hypoc...

Embodiment 2

[0041] This embodiment discloses a production process of anti-myopia paper, comprising the following steps:

[0042] (1) Prepare the following raw materials in parts by mass: 31 parts of straw, 19 parts of reed, 14 parts of mulberry bark, 39 parts of Cizhu, 4.9 parts of boric acid, 9 parts of sizing agent, 4 parts of silicon micropowder, 6.4 parts of talcum powder, 7 parts of earth, 0.18 parts of magnesium oxide, 0.025 parts of magnesium hydroxide, 1.7 parts of aluminum hydroxide, and 8 parts of phosphoric acid.

[0043] (2) Preparation of slurry: select the stalks of straw and reed, tie them into water and soak them in water, take them out when the grass color changes from yellow to light yellow, then soak them in milk of lime, and steam them for 10 hours; take them out and wash away the residual alkali, then The first slurry is obtained by mechanical pulping. Cut mulberry bark and Cizhu into wood blocks with a thickness of 0.5 cm, and then soak them in a 12% sodium hypochlo...

Embodiment 3

[0051] This embodiment discloses a production process of anti-myopia paper, comprising the following steps:

[0052] (1) Prepare the following raw materials in parts by mass: 34 parts of straw, 23 parts of reed, 15 parts of mulberry bark, 44 parts of Cizhu, 5.4 parts of boric acid, 9 parts of sizing agent, 4.2 parts of silicon micropowder, 8 parts of talcum powder, 8 parts of earth, 0.28 parts of magnesium oxide, 0.03 parts of magnesium hydroxide, 1.9 parts of aluminum hydroxide, and 9 parts of phosphoric acid.

[0053] (2) Preparation of slurry: select the stalks of straw and reed, tie them into water and soak them in water, take them out when the grass color changes from yellow to light yellow, then soak them in milk of lime and steam them for 11 hours; take them out and wash away the residual alkali, then The first slurry is obtained by mechanical pulping. Cut mulberry bark and Cizhu into wood blocks with a thickness of 0.6 cm, and then soak them in 14% sodium hypochlorite...

Abstract

The invention belongs to the technical field of papermaking and particularly discloses a production process of myopia prevention paper. The production process comprises the following steps: (1) preparing raw materials; (2) preparing pulp by treating straws and reeds to obtain first pulp and treating wood and cluster bamboo to obtain second pulp; (3) mixing and pulping; (4) preparing mixed liquid;(5) adding filler by mixing and stirring silica micropowder, talcum powder and Dongsheng soil to obtain a mixed filler, adding the mixed liquid into the mixed filler, stirring to obtain a mixed material, adding the mixed material into the pulping liquid, stirring, heating the liquid in the stirring process, and stopping heating when the temperature of the liquid is heated to 78-84 DEG C to obtainpapermaking pulp; (6) drying; (7) calendering; and (8) coiling. The paper produced by the technical scheme has a myopia prevention effect; meanwhile, the produced paper has good properties of strength, smoothness, printing adaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of papermaking, in particular to a production process of anti-myopia paper. 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 functions of color...
