Production method for packaging box paper

Abstract

The invention relates to a production method for packaging box paper. The production method for the packaging box paper includes the following steps: 1, by weight, 60 parts of pteroceltis tatarinowii bark, 40 parts of taxus bark, 0.25 part of baking soda, 3 parts of calcium carbonate and 3 parts of ethyl acetate ethanol solutions are mixed to be kneaded for 2 h; 2, the processed raw materials are added into distilled water with the weight three times that of the raw materials to be stirred for 1 h, and pulp A is obtained; 3, 8 parts of modified starch and 0.2 part of nano-silver are added into the pulp A, and ultrasonic processing is carried out; 4, heat preservation is carried out on the raw materials processed in the step 3 at the temperature of 95 DEG C, and stirring is carried out in the heat preserving process; 5, the processed raw materials are pulped; 6, the processed raw materials are formed through molds and dried, and the packaging box paper is obtained. The production method for the packaging box paper is simple; the pteroceltis tatarinowii bark, the taxus bark and the modified starch are used as the main raw materials, the produced packaging box paper can be naturally degraded, the pollution to the environment is avoided, and the packaging box paper is nontoxic and wide in application range.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a production method of packing box paper. Background technique [0002] In view of the increasing environmental pressure of traditional plastic packaging materials, the development of degradable packaging materials has become the focus of current scientific and technological research. However, due to material and technical problems, the current degradable plastics still cannot be completely degraded, and the cost is high, so they have not yet been put into large-scale production and use. [0003] The packaging material obtained by making paper from natural materials is completely made of natural edible starch, which can be completely degraded and fundamentally solves the problem of environmental pollution. However, in papermaking, the wood part of trees is now mostly used for papermaking, while the roots and bark are less utilized, especially poplars with a faster growth r...

Problems solved by technology

However, in papermaking, the wood part of trees is now mostly used for papermaking, while the roots and bark are less utilized, especially poplars with a faster growth rate, which are rarely used. The reason is the quality of paper made from poplar roots. Poor, not easy to shape, poor tearing and tensile strength of paper
