Problems solved by technology

With the gradual enhancement of people's awareness of environmental protection, my country has also begun to reuse recycled paper production, but the existing recycled paper technology is not yet mature, resulting in difficulties in the use of recycled paper, and people lack confidence in using it. The main problem is That is, the physical properties of recycled paper have declined, such as surface strength, water resistance, and smoothness. In terms of chemical properties, since recycled paper still has a lot of ink dirt and bacteria, it will cause harm to the human body if it is not handled properly. Some recycled paper cannot take into account the two elements of environmental protection and health at the same time

Abstract

The invention relates to the processing field of paper products and discloses regenerated environment-friendly writing paper. The regenerated environment-friendly writing paper contains the following raw materials in parts by weight: 180-200 parts of waste paper pulp, 20-30 parts of leaf pulp, 6-9 parts of ramie size, 5-8 parts of apocynum venetum size, 3-5 parts of cetanol, 1.2-1.5 parts of a coconut oil derivative, 0.2-0.5 part of polyacrylonitrile fiber, 0.1-0.2 part of dimethylformamide, 0.05-0.07 part of zinc chloride, 0.02-0.03 part of tourmaline powder, 0.01-0.02 part of sodium copper chlorophyllin, 0.004-0.006 part of tea polyphenol, 0.005-0.006 part of an antimicrobial deodorant and 0.001-0.002 part of plant essential oil. Waste paper pulp is adequately utilized, and auxiliary materials are added, so that the problem that strength of the waste paper pulp is reduced is solved; and furthermore, the regenerated environment-friendly writing paper has the characteristics of being smooth to write, strong in water resistance, good in glossiness, capable of inhibiting bacteria, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the field of paper product processing, in particular to a recycled environmentally friendly writing paper. Background technique [0002] Recycled paper is made from waste paper, which is crushed, decolorized and pulped through various processes to produce paper. 80% of its raw materials come from recycled waste paper, so it is known as an environmentally friendly paper with low energy consumption and light pollution. There are many kinds of urban waste paper, and different types of waste paper are used as raw materials to make different recycled copy paper, recycled packaging paper, etc. Generally, it can be divided into two categories: one is low-grade paper such as liner paper and toilet paper; the other is paper for books, newspapers and magazines, copy paper, printing paper, postcards and exercise books. The environmental pollution caused by the recycled paper pulping process to the atmosphere and water quality is much lo...
