Abstract
A color paper of taking care of eye health and improving vision is prepared through breaking wheat straw, proportionally mixing it with sodium sulfite, sodium hydroxide and anthraquinone, digestion to become pulp, sieving, adding liquid chlorine, sodium hydroxide and sodium hypochlorinite, thermal bleaching, pulverizing, adding alkaline bright yellow, alkaline green, aluminium sulfate, rosin gum and dithionour acid oil, diluting by water, shaping paper on net and drying.
Description
Technical field the present invention relates to a kind of preparation method of colored vision strengthening paper, belongs to pulp technology for making paper.
What background technology was 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.
The objective of the invention is to propose a kind of preparation method of colored vision strengthening 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 preparation method of the colored vision strengthening paper that the present invention proposes comprises following each step:
(1) wheat straw is pulverized, making fibre length is 30～50 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) in the slurry of step (5), add alkaline bright yellow, Viride Nitens, aluminum sulfate, gum rosin and hydrosulfurous acid oil, thin up pulp density to 0.2～0.3%, to adjust the color of paper pulp, the percentage by weight that its addition accounts for slurry is:
Alkaline bright yellow 0.014%
Viride Nitens 0.005%
Aluminum sulfate 5%
Gum rosin 1.1%
Hydrosulfurous acid oil 0.014%
(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 preparation method of the colored vision strengthening paper that the present invention proposes, change fluorescent whitening agent and bluish violet dyestuff in traditional paper technology, mix the colored vision strengthening paper of lovely luster, good visual effect with dyestuffs such as alkaline bright yellow, Viride Nitenses, it is faint yellow that color and luster is, attractive in appearance but do not lose bright-coloured, do not hinder eyes, reflectance spectrum is 470nm～550nm.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 preparation method of the colored vision strengthening paper that the present invention proposes selects 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 monochlor(in)ate one 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 45 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, Viride Nitens, aluminum sulfate, gum rosin and hydrosulfurous acid oil at last, thin up pulp density to 0.2%, to adjust the color of paper pulp, the percentage by weight that its addition accounts for slurry is: alkaline bright yellow 0.014%, Viride Nitens 0.005%, aluminum sulfate 5%, gum rosin 1.1%, hydrosulfurous acid oil 0.014%, 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.
