Embodiment 1

[0016] A high-performance fully biodegradable plastic, comprising the following components in parts by weight: 20 parts of corn yellow powder, 30 parts of plant starch with a moisture content of 5%, 10 parts of bean dregs, 10 parts of composite plasticizer, 5 parts of glycerin, and 5 parts of ethanol , Water resistant agent - 8 parts of poly(β-hydroxybutyrate), 35 parts of polyvinyl alcohol, 4 parts of chitosan, 10 parts of reinforcing fiber, 5 parts of polycaprolactone and 10100.5 parts of anti-aging agent. Wherein, the vegetable starch is corn starch or potato starch; the composite plasticizer is a mixture of glycerin, polyethylene glycol and water at a mass ratio of 55:15:0. The reinforcing fiber is a mixed fiber in which bamboo fiber, sisal fiber and rice straw fiber are mixed in a ratio of 1:1:3.

Embodiment 2

[0018] A high-performance fully biodegradable plastic, comprising the following components in parts by weight: 30 parts of corn yellow powder, 40 parts of plant starch with a water content of 8%, 15 parts of bean dregs, 15 parts of composite plasticizer, 8 parts of glycerin, and 8 parts of ethanol , Water resistant agent - 15 parts of poly(β-hydroxybutyrate), 55 parts of polyvinyl alcohol, 6 parts of chitosan, 20 parts of reinforcing fiber, 8 parts of polycaprolactone and 10101 parts of anti-aging agent. Wherein, the vegetable starch is a mixture of tapioca starch and pueraria starch in any proportion; the composite plasticizer is a mixture of glycerin, polyethylene glycol and water in a mass ratio of 65:28:5. The reinforcing fiber is a mixed fiber in which bamboo fiber, sisal fiber and wheat straw fiber are mixed in a ratio of 1:1:5.

[0019] The biodegradable plastics in the above embodiments have been determined to have complete water resistance and water seepage resistance...

Abstract

The invention discloses high-performance completely-biodegradable plastic which comprises, by weight, 20-30 parts of corn gluten meal, 30-40 parts of plant starch, 10-15 parts of bean residue, 10-15 parts of composite plasticizer, 5-8 parts of glycerin, 5-8 parts of alcohol, 8-15 parts of waterproof agent, 35-55 parts of polyvinyl alcohol, 4-6 parts of chitosan, 10-20 parts of reinforced fiber, 5-8 parts of polycaprolactone and 0.5-1 part of antiager. Testing shows the biodegradable plastic has completely waterproof and water-seepage-resistant performance, tensile strength of the biodegradable plastic reaches higher than 22 MPa, and elongation at break of the biodegradable plastic is 89-105%. Through reasonable raw material selection and proportion designing, the biodegradable plastic has excellent waterproof performance, high structural strength and high toughness and is excellent in comprehensive performance and wide in market prospect, and amount of plastic waste in China is about to be lowered greatly by applying the biodegradable plastic.

Description

technical field [0001] The invention relates to the field of degradable plastics, in particular to a high-performance fully biodegradable plastic. Background technique [0002] With the development of the plastics industry, the demand for plastic products from all walks of life is increasing. The widespread use of plastic products in daily life greatly enriches and facilitates people's lives, but the waste generated is difficult to decompose and causes a large number of of permanent garbage. my country is a big plastic country and also a country with serious plastic waste pollution. Therefore, the development and use of biodegradable plastics is the only way for the development of my country's plastics industry. [0003] At present, there are many types of fully biodegradable plastics developed by the industry, most of which use plant starch as raw materials, and also realize the efficient and comprehensive utilization of resources. However, most of these plastic products ...
