Embodiment Construction

[0017] Non-limiting examples of the present invention are as follows:

[0018] An anti-static biodegradable plastic prepared from the following components in weight (kg):

[0019] Corn starch 25, peanut meal 12, peanut hull powder 8, mica powder 4, coconut diethanolamide 0.8, polyglycerol ricinol ester 0.15, pentaerythritol stearate 1.5, acetyl tributyl citrate 12, stearin Calcium acid 0.8, erucamide 1.5, polypropylene 12;

[0020] The preparation method of antistatic biodegradable plastic includes the following steps:

[0021] (1) Treat the mica powder at 200-300°C for 3-6 hours, add corn starch, peanut meal and peanut hull powder after cooling, grind uniformly together, and pass through a 300-400 mesh sieve to obtain a mixed powder;

[0022] (2) Add the mixed powder obtained in (1) into absolute ethanol at a solid-to-liquid weight ratio of 1:3-1:4, first ultrasonically disperse for 10-15min, and then add coconut oil acid diethanolamide and pentaerythritol stearin The acid ester is h...

Abstract

The invention discloses an anti-static biodegradable plastic. The anti-static biodegradable plastic is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of corn starch, 10-15 parts of peanut meal, 10-15 parts of peanut shell powder, 3-5 parts of mica powder, 0.5-1 part of coco fatty acid diethanol amide, 0.1-0.2 part of polyglycerol polyricinoleate, 1-2 parts of pentaerythritol stearate, 10-15 parts of acetyl tributyl citrate, 0.5-1 part of calcium stearate, 1-2 parts of erucyl amide and 10-15 parts of polypropylene. The biodegradable plastic disclosed by the invention has good biodegradability, good thermal stability and good anti-static property, has certain water resistance, and relatively good abrasive resistance and corrosion resistance, and is good in usability, low in cost, easily available in raw material, simple and feasible in preparation technology, safe, nontoxic and suitable for occasions with special anti-static requirements; and the use safety coefficient of the material is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of plastics, in particular to an antistatic biodegradable plastic and a preparation method thereof. Background technique [0002] At present, plastics have been widely used in all aspects of people's production and life. With the rapid development of the production and application of plastic products, the growth and consumption of plastics continue to increase. Most of these plastic products are disposable products, and waste plastics are extremely difficult to dispose of, leaving them in the environment as white garbage, which has threatened the balance of the ecological environment and the survival of humans, animals and plants. At the same time, because the plastics industry is based on oil, and oil and natural gas resources cannot meet the growing global demand, shortages have occurred. In order to control white pollution, save energy and resources, and solve the problems of insufficient raw material source...
