Embodiment 1

[0034] Embodiment 1: a kind of production technology of anti-myopia paper, comprises the following steps:

[0035] Step 1, preparing waste thin paper deinked pulp, coniferous wood pulp, and wheat straw pulp respectively;

[0036] Step 2, uniformly mix waste tissue paper deinking pulp, coniferous wood pulp, and wheat straw straw pulp to obtain a mixed pulp. The weight percentages of the three are: waste tissue paper deinking pulp 55%, coniferous wood pulp 15%, wheat straw Straw pulp is supplemented to 100%;

[0037] Step 3, passing the obtained mixed pulp through a pressure sieve, and then using a fiber separator to separate the mixed pulp into fibers, controlling the fiber purity to be greater than 95%, and the impurity removal rate to be greater than 95%;

[0038] Step 4: Add basic bright yellow, tartrazine and sunfast yellow to the separated fiber slurry, and the weight percentages of basic bright yellow, lemon yellow and lightfast yellow in the fiber slurry are 0.03%, 0.03...

Embodiment 2

[0046] Embodiment 2: A production process of anti-myopia paper. The difference from Embodiment 1 is that the percentages by weight of the three are: 60% of waste tissue paper deinking pulp, 13% of coniferous wood pulp, and supplemented by wheat straw pulp to 100%.

Abstract

The invention discloses a production process of anti-myopia paper and relates to the field of papermaking. It comprises the following steps: step 1, preparing waste tissue paper deinked pulp, coniferous wood pulp and wheat straw pulp respectively; step 2, mixing waste tissue paper deinked pulp, coniferous wood pulp and wheat straw pulp evenly to obtain a mixed pulp, the percentage by weight of the three is: waste thin paper deinked pulp 55-65%, coniferous wood pulp 10-15%, wheat straw pulp to make up to 100%; step 3, the mixed pulp obtained is screened through a pressure sieve , and then use a fiber separator to separate the fibers of the mixed pulp, control the fiber purity to be greater than 95%, and the impurity removal rate to be greater than 95%; step 4, add alkaline bright yellow, lemon yellow and sun-fast yellow to the separated fiber slurry, and mix uniform to obtain a colored slurry; Step 5, adding papermaking additives to the colored slurry, and sending it into a paper machine for papermaking, dehydration, and drying to obtain anti-myopia paper. The anti-myopia paper made by the invention has better anti-myopia effect.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production process of anti-myopia paper. Background technique [0002] Present anti-myopia paper generally adopts plant fiber to produce, needs to cut down a large amount of trees and bamboo, and most adopt the mode of adding dyestuff to the white paper after bleaching to prepare anti-myopia paper. [0003] According to the traditional production process, only logs are used to make paper, which causes deforestation, damages the environment, and has high production costs. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a production process of anti-myopia paper, which has the advantages of comprehensive utilization of waste paper resources and reduction of production costs. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] A pr...
