Abstract
The invention discloses one and pre-myopic-preventing flaxen can write paper.The pre-myopic-preventing writing paper of the present invention, its preparation method comprises the following steps, and uses the mixing slurry that hardwood pulp and softwood pulp are prepared according to the weight ratio of 1:0.5-1.3, through bleaching, dissipates slurry, defibrination, the slurry that obtains with slurry, adopts conventional method molding to obtain paper；In described process with slurry, add following component in relative to total pulp weight ratio: alkaline bright yellow 0.01～0.02 ‰, Basic Orange 0.01～0.06 ‰ and benzidine yellow G 0～0.01 ‰, chrysophene G 0.01～0.02 ‰, titanium dioxide 0.1 ‰.Prepared by the present invention writes paper: (1) surface presents faint yellow, and color and luster is soft, it is possible to effectively pre-myopia prevention occurs；(2) fluent writing, the not invariant color of unrestrained ink, long-term storage colour stable；(3) paper can suppress the healthy of the growth protecting user of noxious bacteria.
Description
Technical field
The present invention relates to a kind of writing paper to open, pre-myopic-preventing flaxen can write paper particularly to one.
Background technology
It is reported, adolescents in China myopia sickness rate is 50%～60%, compared with the rate of myopia in the whole world 22%, seriously exceedes international average level.Its students in middle and primary schools are 28%, junior school student is 60%, high school student is 85%, show high correlation at school age.This is big mainly due to Middle school students ' learning pressure, and every day is long in the face of the time of books, big by eye intensity.
The homework book that usual student uses is that white paper printing forms, and homework book brightness is high, and student needs highly to watch the word on the paper that intensity of light reflection is big attentively for a long time in writing process.In this case, student's visual fatigue intensity is big, and vision is gradually reduced, and ultimately results in myopia.
Disclosed in Chinese patent CN102310680 a kind of pre-myopic-preventing thin, being designed with the paper of reflection 510 ~ 590nm gold-tinted, the paper with specific filtration improves the light color and luster of homework book reflection.But this invention only proposes the paper that a kind of appearance colour is yellow, and the preparation method of unexposed paper, and other controls being likely to vision produces the factor of impact.
Summary of the invention
It is an object of the invention to overcome the deficiency only disclosing the imagination using yellow paper in prior art and do not provide the method effectively realizing target imagination, it is provided that a kind of paper that can effectively prepare and play pre-myopia prevention purpose.
In order to realize foregoing invention purpose, the invention provides techniques below scheme:
A kind of pre-myopic-preventing writing paper, uses the mixing slurry that hardwood pulp and softwood pulp are prepared according to the weight ratio of 1:0.5-1.3, through bleaching, dissipates slurry, defibrination, the slurry that obtains with slurry, adopts conventional method to prepare paper.In described process with slurry, add following component in relative to total pulp weight ratio: alkaline bright yellow 0.01～0.02 ‰, Basic Orange 0.01～0.06 ‰ and benzidine yellow G 0～0.01 ‰, chrysophene G 0.01～0.02 ‰, titanium dioxide 0.1 ‰.Paper forming process is sent into calender when the moisture in paper is lower than 7.6wt%, suppresses.
Adopting writing paper prepared by the inventive method, color and luster presents faint yellow, reflective soft, it is possible to effectively alleviate asthenopic generation in process of reading and writing.Particularly by alkaline bright yellow and Basic Orange with the use of, mix according to the ratio of 1:1 to 1:3, the color and luster obtained is particularly soft, and Color highlights.Add chrysophene G, paper color fastness can be made more, in use preserve the longer time, suplementing colorant as alkaline bright yellow and Basic Orange, benzidine yellow G also has same effect, and addition is lower, the color fastness of paper when being used in combination with chrysophene G, stability is particularly pertinent, can keep good stability in the environment of humid.Finally in dyestuff, the present invention also added titanium dioxide, and the addition of titanium dioxide not only has dyeing to brighten, the effect of softening paper color and luster, and titanium dioxide can also suppress microbial growth, increases the stability of paper, health coefficient.It is another object of the present invention to improve the reflection coefficient of paper and scattering coefficient, when in paper, moisture is lower than 7.6wt% time, feeding calender, suppresses, owing to also added a small amount of titanium dioxide, so the paper that compacting obtains, not only surfacing, and scattering coefficient is good.In writing process, paper blotting coefficient, paper surface diffuse-reflectance goes out flaxen soft color, makes the eyes of writer be in relaxation state, does not produce asthenopia.
Further, described bleaching process adopts alkalescence bleaching process.Described alkalescence bleaching process is conventional alkaline bleaching process.
Further, described scattered slurry process adopt horizontal starch dispensing machine to carry out dissipating slurry.
Further, in described defibrination process, refining concentration 28～32wt%, defibrination rotating speed 1200～1650r/min.
Compared with prior art, beneficial effects of the present invention: prepared by the present invention writes paper: (1) surface presents faint yellow, and color and luster is soft, it is possible to effectively pre-myopia prevention occurs；(2) fluent writing, the not invariant color of unrestrained ink, long-term storage colour stable；(3) paper can suppress the healthy of the growth protecting user of noxious bacteria.
