Abstract
The present invention discloses an notebook capable of preventing myopia. It is characterized by that said invention uses yellowish paper containing yellow dyes of cold yellow G and alkali canary yellow O to make the yellowish paper produce yellowish brightness with 51%-59% and can reflect the colour light whose wavelength is 500-550 nm. The brightness of said paper and chromaticity of picture or image printed on the paper can be formed into enough contrast, so that it can produce optimum visual environment so as to can obtain the effect of preventing myopia.
Description
Technical field:
The present invention relates to a kind of books, the exercise-book of using for the student specifically, this exercise instinct effectively prevents and prevents eye fatigue, thereby reaches the purpose of pre-myopia prevention.
Background technology:
The employed paper of present most books is white, and its characteristics are that brightness is strong.But because it produces strong white reflection, and make the eyes fatiguability, become one of reason of bringing out myopia.Chinese patent CN1137980A discloses a kind of myopia prevention books, be in paper pulp, suitably to add an amount of weld or when top sizing, in glue, mix an amount of weld, so that paper flavescence, and then the catoptrical wavelength of change paper, reduce the stimulation of reverberation, play myopic-preventing purpose human eye.But in fact, not all yellow paper all has myopic-preventing effect.And if used paper is any brightness, contrast that can not be suitable with the pattern generating of being printed causes to guarantee all have myopic-preventing effect.
Content of the present invention:
The invention provides a kind of exercise-book, it is characterized in that: it is the light yellow of 51%-59% that used paper manifests brightness.
The invention provides a kind of exercise-book, it is characterized in that: it is the light yellow of 54%-56% that used paper manifests brightness.
The present invention also provides a kind of exercise-book, it is characterized in that containing in the used lurid paper freezing yellow G, the weld of alkaline bright yellow O.
The present invention also provides a kind of myopia prevention exercise-book, and it is characterized in that containing in the used lurid paper according to the former slurry oven dry stock of white material weight is benchmark, is respectively 0.1 ‰-0.5 ‰, 0.1 ‰-0.5 ‰ the yellow G that freezes, the weld of alkaline bright yellow O.
The present invention further provides a kind of myopia prevention exercise-book, but it is characterized in that the coloured light that used light yellow paper reflection wavelength is 500-550nm.
The present invention also provides the purposes of this exercise-book in pre-myopia prevention.
The present invention contains by use freezes yellow G, the light yellow paper of the weld of alkaline bright yellow O is the light yellow of 51%-59% and make used paper manifest brightness, can reflection wavelength be the coloured light of 500-550nm, use more health of eye thereby play, make it more effectively play myopic-preventing effect.
The specific embodiment:
The present invention specifically realizes by following scheme:
Exercise-book of the present invention mainly is the exercise-book that the student uses, and replaces original white paper to print with following light yellow paper.
Used light yellow paper is following production:
1. measure white former slurry, dyestuff directly freezes yellow G, alkaline bright yellow O and industrial salt: they are benchmark with the former slurry oven dry stock of white material weight all, are respectively 0.1 ‰-0.5 ‰, 0.1 ‰-0.5 ‰ and 0.3%-0.5%.
2. produce free rosin size emulsion and aluminum sulfate solution according to the method and the concentration of routine, get the former slurry dilution of different cultivars routinely, the mixing pulp brightness is 78%-80%, is diluted to conventional concentration.Pigment directly freezes yellow G, alkaline bright yellow O and industrial salt are to add water under 50 ℃-70 ℃ the situation to dilute respectively in temperature, two kinds of pigment is 31/10000-32/1000 with the ratio of water weight during dilution, and during the industrial salt thin up, industrial salt is 3/100-31/100 with the ratio of water weight.
3. follow procedure adds various batchings:
In stock white, add the gum rosin emulsion, mix after 10-15 minute, add industrial salt; Mix after 10-15 minute, add and directly freeze yellow G solution; Mix after 10-15 minute, add aluminum sulfate solution; Mix after 10-15 minute, add alkaline bright yellow O solution, mix stand-by.
4. manufacture paper with pulp:
Papermaking is manufactured paper with pulp in the process broken reuse amount less than 15%.
Talcous addition is 15%-25%, and flow-type adds continuously in the taper slurry-stablizing case before flow box.And copy paper according to conventional pulping method.
The paper of Sheng Chaning can be printed to various exercise-books as required according to the method described above.Various exercise-books comprise: matts for example, big calculation, regular script in small characters this, block letters this, check book is plagiarized a book this, the Chinese phonetic alphabet this, the phonetic Tian shape grille note, single line this, two-wire this, English this, Russian this, arithmetic this, or the like.Because the wavelength of the reflecting light frequency spectrum of used paper is particularly suitable for the eyes of human body, and the colourity of the image of printing on the brightness of this paper and the paper forms enough contrasts, thereby form best visual environment, when using this exercise-book to carry out various study and exercise, can play the effect of pre-myopia prevention.
The following examples are explained to the present invention, but do not limit the present invention.Embodiment 1:
1280 kilograms in the former slurry of extracting waste, wherein bleached wheat straw pulp adapted amount is 90%, and bleaching import softwood pulp dosage is that whiteness was 79% after 10%, two kind of slurry amount was mixed, and slurry concentration is 3.2%, and volume is 40000 liters.
