The above patent adjusts the color of the paper pulp by adding the dye and the fixative after bleaching the paper pulp to prepare the myopia-preventing paper, but the adoption of the bleaching agent and the dye can cause certain pollution to the environment and destroy the ecological environment.
Disclosure of Invention
The invention aims to provide a production process of an anti-myopia exercise book, and aims to solve the problem of large environmental pollution caused by preparation of the existing anti-myopia exercise book.
In order to achieve the purpose, the basic scheme of the invention is as follows: a production process of a myopia prevention exercise book comprises the following steps:
(1) preparing the following raw materials in parts by mass: 30-40 parts of straw, 10-20 parts of wood, 42-50 parts of bamboo, 4-7 parts of boric acid, 8-10 parts of sizing agent, 3.8-5 parts of silica powder, 6-8 parts of topaz, 5-9 parts of wollastonite, 1.2-2 parts of magnesium oxide, 0.04-0.06 part of magnesium hydroxide, 1.6-2.2 parts of aluminum hydroxide and 7.5-10 parts of phosphoric acid;
(2) preparing slurry: processing the straws to obtain first slurry; treating wood and bamboo to obtain a second slurry;
(3) mixing and pulping: mixing the first slurry, the second slurry and boric acid together, then pulping, and adding a sizing agent while pulping to obtain a pulping slurry;
(4) preparing a mixed solution: adding aluminum hydroxide into water, stirring, adding 2/5-3/5 of the total amount of phosphoric acid, heating to 60-65 ℃, adding the rest phosphoric acid, continuing heating to 82-88 ℃, adding magnesium hydroxide and 0.12-0.35 part of magnesium oxide, and stirring to obtain a mixed solution;
(5) filling: mixing and stirring the silica micropowder, wollastonite, clockwork and the rest magnesium oxide to obtain mixed filler, adding the mixed solution into the mixed filler, and stirring to obtain a mixed material; adding the mixed materials 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 ℃ to obtain paper pulp;
(6) and (3) drying: coating the paper pulp obtained in the step (5) on a coating machine, and then conveying the paper pulp into a dryer for dehydration and drying to prepare base paper;
(7) ink mixing and printing: blending yellow ink, printing the base paper obtained in the step (6), and printing an ink mesh pattern coating on the base paper;
(8) binding: the printed paper is cut into a suitable size and then bound with the cover sheet of the workbook.
The working principle of the basic scheme is as follows: the method is characterized in that straws, woods and bamboos are used as raw materials for manufacturing paper, the raw materials are mixed with a certain amount of boric acid after being pulped, the boric acid can increase the viscosity of a mixed solution of the first slurry and the second slurry to a certain extent, the retention rate of silica micropowder, wollastonite, bentonite and magnesium oxide added subsequently is improved, meanwhile, the boric acid has an anticorrosion effect, and no preservative is required to be added subsequently. And (4) adding aluminum hydroxide and phosphoric acid into the mixed solution prepared in the step (4), wherein the aluminum hydroxide and the phosphoric acid can react to generate aluminum dihydrogen phosphate, and adding magnesium oxide and magnesium hydroxide can enable the mixed solution to form a better net structure, increase the bonding efficiency of the mixed solution and facilitate the retention of the filler. And (5) stirring the mixed liquid and the mixed filler, wherein the mixed liquid is coated on the surface of the mixed filler, and the filler exists in a form of a composite system, so that the strength of the paper is not obviously reduced due to the addition of the filler, and the strength of the paper is greatly improved.
The beneficial effect of this basic scheme lies in:
1. according to the technical scheme, the straw, the wood and the bamboo are used as main raw materials for manufacturing the paper, so that the deforestation can be effectively reduced. The produced paper is natural light yellow without being bleached, and does not need to be dyed by a dyeing agent, so that the environment pollution caused by the dyeing agent and the bleaching agent is avoided, and meanwhile, the strong light stimulation to human vision is avoided, so that the myopia prevention effect is achieved.
2. The paper is made of straw, wood and bamboo in fixed proportion, and the straw, wood and bamboo fibers are mixed, so that the homework book suitable for writing can be produced. The characteristics of the wood and the bamboo are similar, the wood and the bamboo are pulped together, the fibers of different substances can be fully mixed, and the trouble of independent pulping and the waste of resources are avoided.
3. The wollastonite is in a needle column shape, can be interwoven with plant fibers when being added as a filler to form a net structure, and is not easy to fall off after being added. The silica micropowder can effectively fill the pores between fibers, and can react with alkaline material magnesium oxide to generate gel, thereby being beneficial to the retention of the filler. The clockwork is high-plasticity clay and has high binding force, and is mixed with other fillers to be beneficial to the retention of the fillers in gaps of fibers. Meanwhile, through long-term research, the applicant discovers that the opacity of paper can be effectively increased and the smoothness and the printing performance of the paper can be enhanced by adopting the silica powder, the wollastonite, the magnesium oxide and the bentonite as the fillers.
4. In general, the binding force between fillers such as silica powder, wollastonite, clockwork and the like and fibers is poor, so that the retention rate of the fillers is low, the retention rate is low, the filler is wasted, and the lost fillers cause the problem of difficult waste treatment. According to the invention, the viscosity of the mixed solution of the first slurry and the second slurry is increased to a certain extent by adding boric acid, so that the retention rate of the filler can be improved, the addition amount of the filler can be reduced, and the cost is saved; meanwhile, the added boric acid also has the function of corrosion prevention, and no additional preservative is needed to be added in the subsequent process.
5. The addition of the filler can save the amount of the vegetable fiber and improve certain properties of the paper, but the addition of the filler can seriously deteriorate certain technical indexes of the paper, especially strength indexes. In the invention, the strength of the paper prepared by preparing the mixed solution and adding the mixed solution into the slurry is obviously improved.
Further, the reticular pattern coating in the step (7) is composed of a plurality of regular hexagons with the side length of 0.1-3mm and the line profile of 0.05-1mm, and any one side length of the adjacent regular hexagons is overlapped together to be printed into a honeycomb grid pattern. The coating with a specific color and a specific shape is coated on the paper, so that the wavelength of the reflected light of the homepage can be between 500 and 600nm, and the effect of preventing myopia can be achieved by using eyes in the green light area, thereby achieving the effect of protecting the eyes.
Further, the step (2) of preparing the first slurry comprises the following specific steps: bundling straws, then putting the straws into water for soaking, fishing out the straws when the grass color is changed from yellow to light yellow, then soaking the straws in lime milk, and steaming the straws for 8 to 12 hours; taking out and washing residual alkali, and pulping by a mechanical method to obtain first slurry. The straw is darker, if the paper obtained without treatment is yellow, the paper prepared by the pulp has the reflected color light with the wavelength of 480nm-550nm, and does not have good myopia prevention effect.
Further, the step (2) of preparing the second slurry comprises the following specific steps: cutting wood and bamboo into blocks with thickness of 0.4-0.7cm, and soaking in 10-15% sodium hypochlorite solution for 5-7 hr; after soaking, cooking the wood and the bamboo by a sulfate method to obtain slurry, wherein the specific parameters are as follows: 1: 2.8-3.2, alkali consumption: 17-19% sodium oxide, maximum cooking pressure: 0.72-0.75MPa, maximum cooking temperature: 165-168 ℃, and the cooking time is 6-8 h; and washing and screening the obtained slurry to obtain second slurry.
In the present application, the reason why the block raw material is directly subjected to the bleaching treatment rather than the second slurry after processing is that: the block raw materials are bleached, the bleaching degree is lower than that of the direct bleaching of the second pulp, the raw materials can keep proper light yellow, and the waves reflected by the paper prepared by the raw materials are not easy to cause visual fatigue; and also reduces the environmental pollution caused by directly bleaching the second pulp. Meanwhile, multiple experiments of the applicant show that the wood and the sympodial bamboos are treated within the parameter range, so that the wood and the sympodial bamboos can be made into mixed slurry with good mixture, the trouble of independently treating the wood and the sympodial bamboos is avoided, the operation steps of mixing the wood and the bamboo slurry are reduced, the efficiency is improved, and the resources are saved.
Further, the drying in the step (6) comprises primary drying and secondary drying, wherein the temperature of the primary drying is controlled to be 48-53 ℃, and the time is kept for 1-2 hours; during secondary drying, the initial temperature of drying is controlled at 70-75 deg.C, and the temperature of drying is reduced by 0.2-0.4 deg.C per second until it is reduced to 45-50 deg.C. Compared with primary drying, the paper prepared by secondary drying has smoother surface and better quality. The temperature of preliminary drying is lower, avoids that too high messenger's moisture speed of volatilizing of drying temperature is too fast, leads to the reaction too violent, makes the surface unevenness of paper easily. When carrying out secondary drying, the paper has tentatively stereotyped, and when secondary drying, the temperature speed that makes drying reduces gradually, avoids the high temperature to lead to the paper to lose water too fast, makes the paper crooked, sticks up.
Further, the method also comprises a step of calendering the base paper after the step (6); calendering is carried out by a calender, and the temperature of upper and lower rolls of the calender is controlled at 46-52 ℃ during calendering. Calendering can improve the smoothness and gloss of paper and to some extent can control the caliper of the paper. Through a plurality of tests of the applicant, the temperature of the upper roller and the lower roller of the calender is controlled within the temperature range, and the calendering effect is better.
Further, the timber is wingceltis bark; the bamboo is selected from sympodial bamboo, specifically selected from one of yellow bamboo, green bamboo, Sagittaria trifoliata, and Ma bamboo. The pteroceltis tatarinowii bark is developed in tenacity fibers, and can be mixed with fibers of bamboo and straw to produce paper suitable for writing. The sympodial bamboos grow faster and have higher yield than the scattered bamboos, and the sympodial bamboos are superior to the scattered bamboos as paper making raw materials in terms of fiber morphology and cellulose content.
