Abstract
A both optically and biologically degradable plastics are prepared from high-density low-pressure polyethylene, low-density high-pressure polyethylene, linear PE, filler, pigment, regenerated material and degradable material. Through processing and blowing, said plastics can be made into agricultural film, food bag, packing bag, garbage bag and food container. Its advantages are 100% of degradation, no generation of starch, low cost, no poison and improving soil.
Description
The present invention relates to a kind of biodegradable plastic.It is mainly used in blowing farmland film, food bag, series product such as refuse bag and all kinds of packing bag mess-tins.
At present, the pay attention to day by day environment protection of China governments at all levels is eliminated the relevant rules of " white pollution " and is put into effect in succession.According to People's Railway Newspaper, China's non-degraded cutlery box annual production reaches 5,000,000,000, and more than one hundred million units will be costed every year by single Ministry of Railways, drop into employees up to a million and handle these white garbages, its recovery difficult is big, burns to produce a large amount of obnoxious flavoures, reason is gone into underground a century again and is not rotted, and destroys soil, contaminate environment.
From 1989, respective specified when restriction or forbidding non-degradative plastics packing, is all made by developed countries such as Denmark, English, method, U.S., moral, meaning, day, make the enforcement timetable, the European Community all stopped using non-degradative plastics packing material in 1997.
Existing plastics farmland film, packing bag, food bag, refuse bag and mess-tin all can not be degraded, and promptly are that biodegradable starch-plastics also can not be degraded fully, and produce investment greatly, and its recovery difficult is big, and environmental pollution is serious.
The object of the present invention is to provide a kind of never starch-containingly, and degradation rate is 100%, invests for a short time, is beneficial to the complete degradable plastic of elimination " white pollution ", and its coverage rate is also big by 1/4 than traditional farmland film.Original plastics bag factory needs more exchange device to produce.
This biodegradable plastic not only has external product and absorbs the ultraviolet ray of sunlight medium wavelength between the 290-380 nanometer, and the aging macromole that also causes rapidly of plastics macromole is disintegrated comprehensively, becomes lower-molecular substance, turns to powder, and can be further by microbiological degradation.
The present invention is achieved in that 10kg high-density low pressure polyethylene, the 30kg low-density high-pressure polyethylene, the linear PE of 10kg, 10kg stopping composition, the 8kg colour batch, the 12kg degradable master batch, the 20kg reworked material is after amalgamator stirs, add material bin, the system of inhaling forms at a certain temperature, and its color and degradation time can be adjusted proportion scale and temperature as required.
Claims (2)
- One kind never starch-containing, degradation rate is 100% optical-and bio-degradable plastics.Its farmland film formulation is: low-density high-pressure polyethylene 50-60%Linear PE10-20% stopping composition 10-20%Degradable master batch 10-15% reworked material 10-30%The prescription of its food bag is: high-density low pressure polyethylene 55%Linear PE10-15% stopping composition 10-20%Colour batch 5-10% degradation master batch 10-15%Reworked material 10-30%
- 2. described by claim 1, it is characterized in that: utilize this principle and starting material, resize ratio promptly can be made the different film of degradation time, bag, box plastics.
