Abstract
This invention refers to a kind of peak yellow health-care paper protecting from myopia, and its preparation. The process includes crushing wheat stalk, mixing sodium sulfite, sodium hydroxide and anthraquinone with wheat stalk fibers, steam-boiling the said mixture in water to form paper pulp materials, sifting out them to remove impurities, adding liquid chlorine, sodium hydroxide and sodium hypochlorite into them, heating to bleach pulp materials, pulverizing pulp materials; Adding alkali peak yellow, acid violet, aluminum sulphate, rosin glue, dithionite oil etc into pulp materials, diluting paper pulp with water in order to adjust colour, putting paper pulp on shaped net according to meet finished paper thickness, heating and drying to get products. This health-care paper is peak yellow, pretty and without lost fresh and hurt eyes. Its surface is smoothness, water tolerance and oil tolerance, and physical strength and surface strength reaching the write paper standard.
Description
Technical field
The present invention relates to a kind of manufacture method of bright yellow myopia prevention health care paper, belong to pulp technology for making paper.
Background technology
Traditional writes or publication grade, and its outward appearance generally is white.For making white paper more attractive in appearance, or be fit to certain special purposes, generally all will in the paper pulp of papermaking, add a large amount of fluorescent whitening agents and indigo plant, cudbear etc., with the brightness and the aesthetics of raising paper.The shortcoming of existing paper is that under ordinary ray, the eyes that the reverberation that produces from paper stimulates the user strongly make the user feel visual fatigue easily, cause the rising of the myopia incidence of disease.And the former pulp brightness of the paper of traditional blank sheet of paper to require be 70～75%, therefore association with pulp bleaching agent consumption height in paper-making process, chemical reaction is violent, has increased the difficulty of technology controlling and process.
Summary of the invention
The objective of the invention is to propose a kind of manufacture method of bright yellow myopia prevention health care paper, in paper-making process, add a kind of particular dye, not only change the white appearance of traditional paper, and make color soft attractive in appearance, reduce strong reflective stimulation to eyes, alleviate the user reading, when writing visual fatigue and to the injury of eyes.
The manufacture method of the bright yellow myopia prevention health care paper that the present invention proposes comprises following each step:
(1) wheat straw is pulverized, making fibre length is below 25 centimetres;
(2) add sodium sulfite, NaOH and anthraquinone in wheat straw fiber, and fully mix, the percentage by weight that its addition accounts for wheat straw is:
Sodium sulfite 8%
NaOH 4%
Anthraquinone 0.05%
(3) said mixture is placed on boiling becomes pulp in the water, the concentration of slurry is 2～3%, and boiling temperature is 140～170 ℃, and digestion time is 1～3 hour, the slurry after the boiling is sieved, to remove coarse impurities;
(4) add liquid chlorine, NaOH and clorox in the slurry after boiling, heat to 35～40 ℃, kept 2～5 hours, so that paper pulp is bleached, the percentage by weight that its addition accounts for slurry is:
Liquid chlorine 6%
NaOH 5%
Clorox 2%
(5) slurry of above-mentioned steps (4) is pulverized, making its beating degree is 30;
(6) add alkaline bright yellow, acid purple, aluminum sulfate, gum rosin, hydrosulfurous acid oil and top sizing fixative in the slurry of step (5), the percentage by weight that its addition accounts for slurry is:
Alkaline bright yellow 0.025%
Acid purple 0.001%
Aluminum sulfate 5%
Gum rosin 1.1%
Hydrosulfurous acid oil 0.014%
Top sizing fixative 0.001%, top sizing fixative can be styrene, second propylene or silicate polymer;
Thin up pulp density to 0.2～0.3% is to adjust the color of paper pulp;
(7) according to last paper sheet thickness requirement, it is on the 75 purpose forming nets that the paper pulp of step (6) is layered on specification, and 60～85 ℃ of heating 5～10 seconds down, paper gets product.
The manufacture method of the bright yellow myopia prevention health care paper that the present invention proposes, change fluorescent whitening agent and bluish violet dyestuff in traditional paper technology, mix the bright yellow myopia prevention health care paper of lovely luster, good visual effect with dyestuffs such as alkaline bright yellow, sour purples, color and luster is bright yellow, attractive in appearance but do not lose bright-coloured, do not hinder eyes, reflectance spectrum is 550nm～650nm.The surface smoothing of paper, and water-fast, oil resistivity good, physical strength and surface strength have all reached GB/T12654-1990 writing paper standard.Therefore the present invention has reduced the papermaking cost owing to reduced the kind and the consumption of bleaching agent.
The specific embodiment
The manufacture method of the bright yellow myopia prevention health care paper that the present invention proposes is selected basic-dyeable fibre for use, and with aluminum sulfate as painted precipitating agent, with sodium dithionite as color-fixing agent, with the durability of assurance color and luster.Because of the present invention is lower to the whiteness requirement of former paper pulp, be 55～60%, therefore adopted the tri-stage bleaching technology of alkalization-chlorination-hypochlorite post-bleach, the chemical reaction in the bleaching process is comparatively gentle, makes paper-making process be easy to control.
Below be one embodiment of the present of invention:
Wheat straw is pulverized, making fibre length is about 20 centimetres, in wheat straw fiber, add sodium sulfite, NaOH and anthraquinone, and fully mix, the percentage by weight that its addition accounts for wheat straw is: sodium sulfite 8%, NaOH 4%, anthraquinone 0.05% is placed on said mixture that boiling becomes pulp in the water, and the concentration of slurry is 3%, boiling temperature is 150 ℃, digestion time is 2 hours, and the slurry after the boiling is crossed sieve twice, and primary screen aperture is 8 millimeters, it is 2.2 millimeters for the second time, to remove coarse impurities; Add liquid chlorine, NaOH and clorox in the slurry after boiling, heat to 40 ℃, kept 3 hours, so that paper pulp is bleached, the percentage by weight that its addition accounts for slurry is: liquid chlorine 6%, NaOH 5%, clorox 2%, slurry is pulverized, and making its beating degree is 30; Go into alkaline bright yellow at last, acid is purple, aluminum sulfate, gum rosin, hydrosulfurous acid oil and top sizing colouring agent, thin up pulp density to 0.2%, to adjust the color of paper pulp, top sizing colouring agent wherein is a styrene, the percentage by weight that its addition accounts for slurry is: alkaline bright yellow 0.025%, acid purple 0.001%, aluminum sulfate 5%, gum rosin 1.1%, hydrosulfurous acid oil 0.014%, top sizing colouring agent 0.001%, according to last paper sheet thickness requirement, it is on the 75 purpose forming nets that paper pulp is layered on specification, heats 8 seconds down at 70 ℃, and paper gets product.
