Problems solved by technology

[0003] For example, the preparation method of hydrophobic wrapping paper provided in Chinese Patent Publication No. 201810290734.6 is basically described as follows: apply the hydrophobic coating on the surface of kraft paper by rolling method, put it in an oven to heat and keep warm after drying, and then Put it aside for 24 hours, that is, the hydrophobic coating is composed of 2-5 parts by weight of nano-silica, 0.5-1 part of nano-titanium dioxide, 30-40 parts of cyclohexane, 100-150 parts of silicone resin, 1-3 parts of color-fixing agent, 2-5 parts of acrylic acid, 1-4 parts of methyl methacrylate, and 2-5 parts of initiator. It produces a relatively strong smell, which affects the user's experience and normal use, which is not conducive to the improvement of the environmental protection of paper, and it is difficult to meet the wider needs of modern people.

Abstract

The invention relates to the technical field of papermaking, and discloses a preparation method of environment-friendly packaging paper. The environment-friendly packaging paper comprises the following raw materials in parts by weight: 50-100 parts of a paper pulp raw material, 50-100 parts of heavy calcium carbonate, 30-60 parts of fragrant particles, 80-100 parts of gloss oil, 100-130 parts of organic silicon resin, 50-80 parts of an anti-scraping agent, 30-60 parts of a color fixing agent, 30-60 parts of latex, 20-50 parts of nano silicon dioxide, 15-30 parts of nano titanium dioxide, 30-40parts of cyclohexane and 20-50 parts of acrylic acid. According to the preparation method of the environment-friendly packaging paper, the paper pulp raw material, the heavy calcium carbonate, the fragrant particles, the gloss oil and the organic silicon resin are matched for proportioning so that the paper can be more effectively prevented from generating strong smell, the use experience of a user is further improved, the normal use of the user is guaranteed, and the harm to the body of the user is effectively reduced; the environmental protection property of the paper is greatly improved, the wider requirements of modern people can be better met, and the use convenience is further improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing environmentally friendly wrapping paper. Background technique [0002] Paper packaging materials are considered to be the most promising green packaging materials in the evaluation of LCA due to their rich resources, easy recycling and easy degradation. With the improvement of people's living standards, the paper packaging industry is developing more and more rapidly. The scope of application of paper is also constantly expanding. In the packaging of vegetables, food, home appliances, and industrial products, paper is required to have certain waterproof performance. Therefore, more and more researches are devoted to the waterproof treatment of paper. The chemical functional groups are hydrophilic, modify the surface of the paper, give the surface of the paper hydrophobic, and form a lotus leaf effect close to the bionic on the surface of the paper, whic...
