Embodiment 1

[0034] A preparation method of a biodegradable material comprises the following steps:

[0035] 1) Granulation: 21 kg of corn fiber and 9 kg of PP were mixed by a high-speed mixer, and then granulated by a twin-screw granulator; The section temperature is set to 120°C;

[0036] 2) Dehydration and cooling: Dehydrate the prepared granules, dry them, and air-cool them, then put them into a mixing bucket and stir for 30 minutes to mix well;

[0037] 3) Drying: Bake the cooled granules at 110°C for 35 minutes to obtain biodegradable granules;

[0038] 4) Injection molding: The obtained biodegradable particles are processed by conventional injection molding process to make a biodegradable plastic box.

Embodiment 2

[0040] A preparation method of a biodegradable material comprises the following steps:

[0041] 1) Granulation: 18 kg of corn fiber and 12 kg of elastomer were mixed by a high-speed mixer, and then granulated by a twin-screw granulator. The temperature of stage 5 is set to 120°C;

[0042] 2) Dehydration and cooling: Dehydrate the prepared granules, dry them, and air-cool them, then put them into a mixing bucket and stir for 30 minutes to mix well;

[0043] 3) Drying: Bake the cooled granules at 100°C for 40 minutes;

[0044] 4) Internal mixing: set the temperature of the internal mixer to 110°C, then put the dried granules into the internal mixer, add 0.32 kg of additives and mix for 10 minutes, and open the machine cover at different temperatures during mixing Turn over the material, the whole process is a total of 6 times, the process is as follows:

[0045]

[0046] 5) Opening: Set the temperature of the 18-inch open mill to 110°C, thin it twice to make the thickness ...

Embodiment 3

[0049] A kind of biodegradable material, its preparation method comprises the following steps:

[0050] 1) Granulation: 14 kg of corn fiber and 6 kg of elastomer were mixed by a high-speed mixer, and then granulated by a twin-screw granulator. The temperature of stage 5 is set to 120°C;

Abstract

The invention discloses a biodegradable material and a preparation method thereof. The preparation method of the biodegradable material comprises the following steps of: granulating main raw materials, dewatering, cooling, and drying to obtain biodegradable granules, or mixing, milling and foaming under oil pressure to obtain the biodegradable foam material, wherein the main raw materials are corn fiber and plastics. Because the biodegradable corn fiber is used as the raw material for preparing the biodegradable material, the dependence on petroleum of the traditional plastics can be changed, and the problems that plastics and rubber easily generate toxic and unpleasant odor during combustion can be improved. In addition, the biodegradable material has good static electricity resistance and slipping resistance, is friendly to skin, can not cause adverse effects on plants and soil after being degraded, can replace EVA, PVC, rubber and other materials to be used for producing all kinds of plastic products such as shoes, mats, toys and bags and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a biodegradable material and a preparation method thereof. Background technique [0002] Traditional plastics occupy a major market share in daily plastic consumption due to their light weight, low price, oil and water resistance, and other advantages. However, discarded plastic materials are not degradable under natural conditions, causing serious environmental pollution. In addition, traditional plastic materials use non-renewable petrochemical resources as raw materials, and the massive consumption of petrochemical resources has caused a global energy crisis. Therefore, in order to solve the serious problems of environmental pollution and resource shortage, the research and development of new degradable materials has become an important topic since the 1970s. [0003] Cellulose, as the most abundant natural polymer on earth, has abundant sources and is a chemica...
