Embodiment 1

[0028] Embodiment 1: biodegradation of natural plant cellulose material, comprising a masterbatch consisting of the following components by weight percentage:

[0029] Derivatives of natural plant cellulose 55%

[0030] Protein 25%

[0031] Vegetable oil 5%

[0032] Dextran 15%

[0033] The above-mentioned derivative of natural plant cellulose is one of cellulose acetate, cellulose propionate, cellulose butyrate or cellulose acetate butyrate.

[0034] The production process is as follows:

[0035] In order to obtain one of the above-mentioned derivatives of natural plant cellulose, the corresponding natural plant cellulose is firstly pretreated, and the pretreatment process is to ferment and dry the corresponding natural plant cellulose. After pretreatment, derivatives of natural plant cellulose, such as cellulose acetate, are obtained.

[0036] Then 55% by weight of cellulose acetate, 25% of protein, 5% of vegetable oil, and 15% of dextran are processed through blending,...

[0052] Vegetable oil 3%

[0053] Dextran 17%

[0054] The above-mentioned derivative of natural plant cellulose is a mixture of cellulose acetate and cellulose propionate.

[0055] The production process is as follows:

[0056] First, the corresponding natural plant cellulose is pretreated, and the pretreatment process is to ferment and dry the corresponding natural plant cellulose. After pretreatment, a mixture of cellulose acetate and cellulose propionate, a derivative of natural plant cellulose, is obtained.

[0057] Then, the cellulose acetate, protein, vegetable oil, and dextran in the above weight percentages are processed through blending, polymerization, extrusion, etc. to obtain a granular masterbatch.

[0058] Finally, the granular masterbatch is plasticized a...

Abstract

The invention discloses a biodegradation natural plant cellulose material, which belongs to a biodegradation material and is aimed to solve the problem of the prior art that biodegradation is not achieved and the environment is polluted. The biodegradation natural plant cellulose material contains master batches with the following weight percentages: 50 to 60 percent of natural plant cellulose derivatives; 20 to 30 percent of protein; 1 to 5 percent of vegetable oil; 10 to 20 percent of dextran; and accessories with the following weight percentages can be added on the basis of the master batches: 0.1 to 0.15 thousandth of LTHO auxiliaries; 10 to 20 percent of linear PE7042; 30 to 60 percent of PE; and the remainder components are the master batches. The products produced in the decomposition of the cellulose materials are soil humic acid and carbon dioxide. The thin film produced by the material of the invention is widely applicable to the technical fields of agricultural films, dailynecessities packaging, industrial packaging, etc.

Description

technical field [0001] The invention belongs to a biodegradable material, in particular to a biodegradable material of natural plant cellulose. Background technique [0002] In the 1870s, people began to use starch and polyethylene blends as materials and roll them into films. Buried in the soil and turned into powder, it is believed that polyethylene has been biodegraded, so various processing methods have emerged to make so-called "biodegradable" polyethylene. In the early 1990s, the progress of polymer chemistry technology found that the C-C bond in the above materials cannot be enzymatically and hydrolyzed, and the bond must be broken unless it is photolyzed and oxidized. In fact, polyethylene is only fragmented and remains in the soil. [0003] Therefore, the development of fully biodegradable materials has become a new topic. Natural polymer materials, especially polysaccharide natural polymer materials, are not only completely biodegradable, but also renewable resou...
