[0040] 1) Put the various materials in a high-speed mixer, heat up and mix evenly, the temperature is 110° C., and the time is 25 minutes to activate the starch surface.
[0041] 2) Transfer the above mixture into a low-speed mixer, and cool it while stirring, so that it is mixed evenly and does not agglomerate.
[0042] 3) Put the above mixture in a twin-screw plastic extruder, heat, melt, plasticize and mix to form a uniform melt, and extrude and granulate.
[0056] 1) Put the various materials in a high-speed mixer, heat up and mix evenly, the temperature is 106° C., and the time is 20 minutes to activate the starch surface.
[0057] 2) Transfer the above mixture into a low-speed mixer, and cool it while stirring, so that it is mixed evenly and does not agglomerate.

Abstract
The invention relates to a chaffstarch completely-biodegradable environmental protection material in the plastic manufacturing field. The chaffstarch completely-biodegradable environmental protection material comprises the following components in percentage by weight: 50%-80% of starch, 15%-30% of polyvinyl alcohol, 8%-18% of plasticizer and 1%-5% of reinforcing agent. The plastic manufacturing method comprises the following steps of: placing the material in a high-speed mixer for mixing for 15-50 minutes at 90 DEG C to 150 DEG C, so that the surface of the starch is activated; placing the mixed material in a double-screw plastic extruder for extruding and pelletizing; and manufacturing the biodegradable material by using the chaff starch as the main material, wherein the technical indexes of the biological plastic reach the level of the existing common plastic, the degrading time can be controlled within 2-18 months and the degradation product are carbon dioxide and water without environment pollution. The chaff starch completely-biodegradable environmental protection material is successfully produced from a material mixer, a pelletizer to a film blowing machine, so that pelletizing and film blowing can be continuously and stably carried out; moreover, the formula, the equipment and the production process are mature, and therefore, the chaff starch completely-biodegradable environmental protection material has a popularization value.
Description
technical field [0001] The invention relates to the field of plastic material manufacturing, in particular to a complete biodegradable environmental protection material of chaff starch. Background technique [0002] The emergence of plastic material products has improved the quality of modern human life and promoted the progress of human social civilization. Today, all aspects of food, clothing, housing, transportation, communication and entertainment that are closely related to people's lives are closely related to plastic products. Plastics enrich people's lives, bring convenience and benefits to people, and become indispensable in daily life. As part of the population, plastic products can be seen wherever there are crowds. [0003] The following is just an example of the important contribution of plastic products from the clothes people wear. [0004] Since ancient times, natural fibers such as cotton, hemp, silk and wool have been used as the source of clothing, but t...
