Problems solved by technology

However, since waste plastics will produce harmful gases and pollute the environment when they are incinerated or reprocessed, it can be said that the disposal of waste plastics is still a major headache in environmental protection work.
[0005] The use of paper bags made from plants to replace ordinary plastic bags has become the mainstream now, but ordinary paper bags are not tough enough due to the hydrophobicity of the paper, and are prone to breakage; the smoothing agent or sizing agent added in the papermaking process is not properly selected. It will also cause secondary poisoning of the prepared paper bags to the human body; and the use of wood to make paper requires cutting down a large amount of wood and destroying green vegetation, which will cause even greater problems in the later stage

Embodiment 1

[0020] A preparation method for making recyclable paper bag raw materials, comprising the following steps:

[0021] (1) Raw material pretreatment: select the fresh adult leaves of the vine of the lily family, soak them in the fermentation tank, use microorganisms to decompose the mesophyll, and maintain the temperature of the fermentation environment at 26-30°C. After the mesophyll is completely decomposed, filter to obtain the leaf film of the vine , wash and set aside.

[0022] (2) Broken leaf film: crush the leaf film obtained by the pretreatment with a crusher to 80-100 mesh.

[0023] (3) Pulp making: Pour the broken vine vine leaf film into the pulp making tank, add an equal amount of hydroxymethyl cellulose with a mass fraction of 0.1%, and stir evenly to make leaf film pulp.

[0024] (4) Water absorption: the leaf membrane slurry prepared in step (3) is absorbed into a uniform film shape with a vacuum carrier mold, and excess water is removed by a water absorption mach...

Abstract

The invention discloses a method for preparing a recyclable paper bag raw material. The method comprises the following steps: by adopting a natural fermentation mode, dissolving pulp of smilax scobinicaulis leaves so as to obtain a leaf membrane; crushing the made leaf membrane, adding 0.1-0.3% by mass of hydroxymethyl cellulose, and uniformly mixing the components for pulping; after pulping, removing extra moisture by using a moisture sucker, and further carrying out hot-press molding, so as to obtain the recyclable paper bag raw material. By adopting the method, the 0.1-0.3% by mass of the hydroxymethyl cellulose which is used as a smoothing agent and a gluing agent is used in the pulping process, so that the tension resistance, the pressure breaking resistance and the kneading propertyof the prepared recyclable paper bag raw material can be greatly improved, and in addition, the recyclable paper bag raw material is harmless to human bodies; and the recyclable paper bag raw materialprepared by using the method can be adopted to make woven bags for replacing plastic bags, can be recycled, can be degraded in the nature, and is capable of reducing ''white pollution''.

Description

technical field [0001] The invention relates to the technical field of papermaking technology, in particular to a preparation method for making recyclable paper bag raw materials. Background technique [0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily life and are often used to hold other items. It is widely used because of its advantages of cheapness, light weight, large capacity and easy storage, but its production and use are banned by some countries due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags. [0003] China's annual output of plastics is 30 million tons, and its consumption is more than 6 million tons. If plastic bags are calculated based on 15% of the annual plastic waste, the annual plastic waste in the world is 15 million tons, and the annual plastic waste in China is more ...
