Description
Technical field
The present invention relates to a kind of pulp technology for making paper, be specifically related to a kind of production method of light grey antifatigue paper.
Background technology
People's blank sheet of paper used in everyday, there is the reflection of white full range, stimulation is had to eyes, traditional books paper has impact to eye in near-distance reading, it can produce near-distance reading pupil expand and closely the brightness contradiction that increases pupil contraction depending on state, depending on receive during surplus body white light set off by contrast black and distortion dispersion viewpoint depending on state and colour make depending on colour cast backward other look can realize require institutional framework adjustment to meet them correctly look effect, this all can impel kopiopia.The patent No. be 95111654 to patent discloses a kind of myopic-preventing book thin, the reverberation proposing " in different visual environments, visual capacity and degree of fatigue are different " white book printing paper can suppress colour vision function, reduce visual capacity; White reflective light can cause maximum visual fatigue while causing high-high brightness contrast, and this fatigue environment is easy to cause myopia.Advocate to use yellow paper to print student's book thin for this reason.The patent No. be 98110785 patent also disclose the thin paper using of a kind of near-sighted book, advocate to use green paper to print book thin, the thin reverberation really to some extent solved due to white paper of these new books suppresses colour vision function, reduce visual capacity, easily cause the problem of myopia, but yellow and green reverberation frequency spectrum is all a wider scope, such as, in the vision of people, yellow, the yellow that particularly purity is higher, be easy to most in all colours cause asthenopic color, it often caused strong Eye irritation, when display screen operation, yellow is exactly clearly by as one of background that should not use, green reflecting light spectral range is 530 ~ 580nm, comprise light green, medium green and blackish green, although there is the green case as myopia prevention homework book in the market, but standard spectrum luminous efficiency≤0.9154 of this kind of green (spectral range is 570 ~ 580nm), can not play anti-asthenopic effect well.And grey paper, it solves pupil contradiction with low-light level and looks state, with can reflective white font solve distortion dispersion viewpoint look state, also solve the impact of coloured light on eye with colourless, and reduce the energy consumption of light process with the dazzle caused compared with low contrast solution high-contrast and low-light level.Therefore, grey paper wrongly written or mispronounced character books can effective relieving eye strain.
Because current paper generally adopts string to produce, and major part adopts the white paper after bleaching to add the mode of dyestuff to prepare paper, adopt bleaching agent and dyestuff, certain injury is caused to environment, adopt log to manufacture paper simultaneously, cause the felling of forest, destroy environment.Traditionally production technology, the main raw material adopted in papermaking is not straw pulp, is exactly wood pulp, and wherein caused social reality problem is a lot, and such as environmental pollution is large, production cost is high.This project adopts secondary stock waste paper as main production raw material, for alleviation China paper making raw material resource pressure, improves waste and old resource utilization, reduces production cost, promote recycling economy socialization, have very significant realistic meaning.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of production method of antifatigue paper, the paper of output is warm grey, saturation degree is 70-90%, and lightness is 20-45%, can effective fatigue-relieving, production process is little to environmental injury, and cost is low.
A production method for light grey antifatigue paper, is characterized in that this, comprises following steps:
(1) waste paper or wheat straw pulper are broken into granularity and are less than below 2mm, slurry concentration is the shredded paper slurry of 5-20%;
(2) sieved through pressurized screen by the shredded paper obtained slurry, pressure is 2-4MPa, and mesh size is 2-5mm;
(3) adopt defibrator that shredded paper slurry is carried out fiber separation, the fiber fineness obtained is greater than 95%, impurity removal rate more than 92%;
(4) isolated fiber to be sized mixing colouring, carbon black, titanium dioxide, aluminum sulfate, gum rosin are added in fibre stuff, the percentage by weight that its addition accounts for slurry is: carbon black 0.1%-0.5%, titanium dioxide 1-5%, aluminum sulfate 5-10%, gum rosin 1.1-2.5%, mix and blend 30-120 minute, mixing temperature is 30-50 DEG C;
(5) dehydration forming, mixed slurry drying and dewatering is shaping, and bake out temperature is 80-160 DEG C, drying time is can obtain antifatigue paper in 5-30 minute.
Solid retains through flocculation filtration by the impurity through being separated in described step 3, and residue waste water filters after alkaline chemical precipitation metal ion, then through charcoal absorption and quartz sand filtration, then waste water is arranged outward.
In described step 5, drying and dewatering adopts two-sided oven dry.
The granularity of described carbon black is 0.5-5um, and the granularity of described titanium dioxide is 1-10um.
Waste paper or wheat straw is adopted to manufacture antifatigue paper, effectively reduce the felling of forest, reduce cost, adopt pressurized screen and defibrator to realize the at utmost purifying of fiber simultaneously, adopt carbon black, titanium dioxide directly and fibers mixture prepare antifatigue paper, avoid the use of bleaching agent, decrease the injury to environment, the light gray simultaneously produced is softer, antifatigue better effects if.Adopt double dewatering drying technology, enhance productivity, improve the quality of paper simultaneously.
The invention has the beneficial effects as follows: a kind of production method of light grey antifatigue paper, the paper of output is warm grey, and saturation degree is 70-90%, and lightness is 20-45%, can effective fatigue-relieving, and production process is little to environmental injury, and cost is low.
