Embodiment 1

[0020] A kind of environment-friendly paper for protecting eyesight, comprising a paper substrate coated with a layer of protective coating; the substrate includes the following components: 70g of plant fiber, 18g of kaolin, 2g of water repellent, 18g of carboxylated styrene-butadiene latex, Gur Glue 3g, silicone acrylic resin emulsion 15g, sodium carboxymethyl cellulose 14g, cellulose fiber 3g; Described protective coating is to adopt modified melanin sizing material to form, and the coating amount of modified melanin sizing material is 2g / m 2 . Wherein, the modified melanin rubber is prepared by the following steps: dissolving 5 g of sodium metasilicate and 3 g of 2-methyl-2,4-pentanediol in 5 times deionized water, adding 1 g of carboxymethyl fiber Stir until the pigment dissolves, then add melanin powder whose mass is 15-18% of the total amount of the mixture, the particle size of the melanin is less than 200nm, and add ethanol 2-3 times the total amount of the mixture a...

Embodiment 2

[0022] A kind of environment-friendly paper for protecting eyesight, comprising a paper substrate coated with a layer of protective coating; the substrate includes the following components: 74g of plant fiber, 14g of kaolin, 3g of water-resistant agent, 16g of carboxylated styrene-butadiene latex, Gur Glue 5g, silicone acrylic resin emulsion 12g, sodium carboxymethyl cellulose 15g, cellulose fiber 2g; Described protective coating is to adopt modified melanin sizing material to form, and the coating amount of modified melanin sizing material is 15g / m 2 . Wherein, the modified melanin rubber is prepared by the following steps: dissolving 5 g of sodium metasilicate and 3 g of 2-methyl-2,4-pentanediol in 5 times deionized water, adding 1 g of carboxymethyl fiber Stir until the pigment dissolves, then add melanin powder whose mass is 15-18% of the total amount of the mixture, the particle size of the melanin is less than 200nm, and add ethanol 2-3 times the total amount of the mi...

Embodiment 3

[0024] On the basis of the ratio of the modified melanin compound in Example 1, 0.3 g of polyvinyl alcohol, 0.8 g of sorbitan monooleate and 0.1 g of sodium dodecylbenzenesulfonate were added.

Abstract

The invention relates to the technical field of paper making and particularly relates to eyesight-protecting environment-friendly paper. The eyesight-protecting environment-friendly paper comprises a paper base body, wherein the base body is coated with a protective coating; the base body comprises the following ingredients in parts by weight: 70-74 parts of vegetable fibers, 14-18 parts of kaolin, 2-3 parts of water repellent agent, 16-18 parts of carboxylated styrene-butadiene latex, 3-5 parts of guar gum, 12-15 parts of silicone acrylate resin emulsion, 14-15 parts of sodium carboxymethyl cellulose and 2-3 parts of cellulose fibers; the protective coating is formed through coating a modified melanin sizing material. Ultraviolet light and blue light irradiating the paper are absorbed, and reflected ultraviolet light and blue light are reduced, so that the paper is soft in luster and good in visual effect. During long-term reading, visual fatigue and visual injury caused by light pollution can be avoided.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an environment-friendly paper for protecting eyesight. Background technique [0002] With the rapid development of social production, energy and the environment have become two major issues that the whole society pays more and more attention to, thus putting forward higher requirements for energy saving and environmental protection. Light pollution is a new source of environmental pollution after waste gas, waste water, waste residue and noise pollution, mainly including white light pollution, artificial daytime pollution and colored light pollution. Light pollution is threatening people's health. In daily life, the common light pollution conditions of people are mostly the dizziness of pedestrians and drivers caused by the reflection of mirrored buildings, and the discomfort caused by unreasonable lights at night. [0003] The light reflection coefficient of white book pap...
