Embodiment 1

[0016] The invention provides an anti-myopia booklet and a production method. The composition is as follows in parts by weight: softwood long fiber bleached chemical pulp accounts for 60-100 parts, mechanical wood pulp accounts for 80-150 parts, and alkaline bright yellow: 2 parts- 10 parts, benzidine yellow: 10-20 parts, titanium dioxide: 20-30 parts, realgar: 20-30 parts, polyacrylonitrile fiber: 50-70 parts, acrylamide copolymer: 1-10 parts , calcium carbonate: 20-50 parts and cationic starch: 60-70 parts.

[0017] The preparation method comprises the following steps:

[0018] (1) Use a pulper to crush waste paper or wheat straw into shredded pulp with a particle size of less than 1mm and a slurry concentration of 5-10%, and pass the obtained shredded pulp through a pressure sieve with a pressure of 2 MPa and a sieve. The hole diameter is 3mm;

[0019] (2) Bleaching the ground wood pulp, and grinding and pressing the bleached pulp, so that the length of the pulp is 1-2 mm...

Abstract

The invention discloses a myopia-preventing book and a manufacturing method thereof. The myopia-preventing book comprises, by weight, 60-100 parts of needlebush long fiber bleached chemical pulp, 80-150 parts of mechanical wood pulp, 2-10 parts of auramine, 10-20 parts of benzidine yellow, 20-30 parts of titanium dioxide, 20-30 parts of realgar, 50-70 parts of polyacrylonitrile fiber, 1-10 parts of an acrylamide copolymer, 20-50 parts of calcium carbonate and 60-70 parts of cationic starch. Light yellow myopia-preventing paper is made in the invention, can reflect specific frequency spectrum colored light, and can be matched with other color lights to form suitable contrast in order to effectively improve the influence of white full-frequency light on eyesight, the adopted paper displays light yellow with the brightness of 60-55% and can reflect colored light with the wavelength of 500-700 nm, and enough contrast is formed between the brightness and the chromaticity of characters on the paper in order to form an optimal visual environment, so when the book is used, the myopia prevention effect can be achieved.

Description

technical field [0001] The invention relates to the field of paper production, in particular to an anti-myopia booklet and a production method. Background technique [0002] The white paper that people use every day has white full-frequency reflection, which is irritating to the eyes, and the light yellow anti-myopia paper can reflect a specific spectrum of color light, which matches other color lights and has a suitable contrast, which can effectively improve the white full-frequency light. The impact on vision can achieve the effect of preventing myopia. Because yellow paper can absorb blue light and purple light that are harmful to the eyes, while white paper has white full-frequency light reflection, which is irritating to the eyes. Relatively speaking, yellow paper can relieve visual fatigue. Since the current anti-myopia paper is generally made of plant fibers, and because a large number of primary and secondary school students need to use paper for homework exercises...
