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
The present invention relates to degradative plastics field, particularly relate to a kind of high-performance complete biodegradable plastics.
Background technology
Along with the development of plastics industry, all trades and professions are increasing to the demand of plastic, plastic in daily life commonly use life that is greatly abundant and that facilitate people, but the garbage produced causes substantial amounts of permanent rubbish owing to being difficult to decomposition.China is plastics big countries, is also the with serious pollution country of plastic garbage simultaneously, and therefore, development and use biodegradable plastic are the only way which must be passed of China's plastic industry development.
At present, the plastics kind of the fully biodegradable of industry exploitation is a lot, mostly with plant amylum for raw material, also achieves the high-efficiency comprehensive utilization of resource.But in use mostly there are the following problems for these plastic products: 1, water resistance is not enough, has infiltration phenomenon；2, intensity and toughness are not fully up to expectations.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of high-performance complete biodegradable plastics, it is possible to solve the weak point that existing biodegradable plastic exists in water resistance and mechanical property.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: provide a kind of high-performance complete biodegradable plastics, including following parts by weight of component: maize yellow-powder 20～30 parts, plant amylum 30～40 parts, 10～15 parts of bean dregs, composite elasticizer 10～15 parts, glycerol 5～8 parts, ethanol 5～8 parts, water-proofing agent 8～15 parts, polyvinyl alcohol 35～55 parts, chitosan 4～6 parts, fortifying fibre 10～20 parts, pla-pcl 5～8 parts and 0.5～1 part of age resistor.
In a preferred embodiment of the present invention, described plant amylum is at least one in corn starch, tapioca, Radix Puerariae starch and potato starch.
In a preferred embodiment of the present invention, the moisture content of described plant amylum is 5～8%.
In a preferred embodiment of the present invention, described composite elasticizer is glycerol, Polyethylene Glycol and the water mixture with mass ratio 55～65:15～28:0～5.
In a preferred embodiment of the present invention, described water-proofing agent is poly-(beta-hydroxy-butanoic acid ester).
In a preferred embodiment of the present invention, described fortifying fibre is the composite fibre that bamboo fibre, sisal fiber and stalk fibre mix with the ratio of 1:1:3～5.
In a preferred embodiment of the present invention, described stalk fibre is rice straw fiber or wheat stalk fiber.
The invention has the beneficial effects as follows: one high-performance complete biodegradable plastics of the present invention, it is by rational material choice and proportion design, biodegradable plastic is made to have the water resistance of excellence, higher structural strength and good toughness, excellent combination property, wide market, it applies the quantity that will greatly reduce China's plastic garbage.
