Description
Technical field
The present invention relates to a kind of nano-micelle that can be used for environment universality degradative plastics goods with and in the purposes of manufacturing environment degradative plastics goods, also relate to by said composition prepared various can environment degradable packaging field or disposable plastics and plastics.
Background technology
Along with the continuous increase of plastics demand in national economy all departments, plastics output improves rapidly, and world's plastics ultimate production had reached 2.12 hundred million tons in 2004, expected 2015 and will reach 300,000,000 tons.Meanwhile, a large amount of waste plastics have caused " white pollution " because of its non-degradable.In recent years, for solving " white pollution " problem, people have developed novel plastics such as photodegradable plastics, filled-type biodegradable plastic, complete biodegradable plastics.

Chinese patent application numbers 95121178.1 and Chinese patent application number 99100726.3 reports add the method for starch and induce biological degradation by part in plastic raw materials, make what is called " filled-type biodegradable plastic ".For " filled-type biodegradable plastic " (as starch filled type, PCL filled-type, PHB filled-type etc.), additive degraded often, and tangible degraded does not take place in polymkeric substance itself, and a large amount of cracked more difficult recyclings of plastics have increased the pollution intractability on the contrary.And the adding of a large amount of weighting materials often reduces the physicals of plastics, makes it be difficult to adapt to the demand in market because of difficult quality and existing plastics compare favourably.
Chinese patent application numbers 95191396.4 and Chinese application number 200710115667.6 reports utilize starch and synthesizing polyester to make complete biodegradable plastics.But shortcomings such as having production cost height, processing difficulties, the crisis in food that increases the weight of, bad mechanical property though such degradative plastics can be degraded fully; and be difficult to practicability; more can't substitute conventional plastic, also can't separate " white pollution " problem that conventional plastic causes.
Oxidation-biodegradable plastic that the organic acid salt that passes through containing transition metal in plastic substrate (cobalt stearate, cerium stearate etc.) of U.S. Pat 005854304 report and natural poly-basic organic acid (citric acid, fumaric acid etc.) are made.The plastics that oxidation-biodegradation plastic makes as class comprehensive utilization oxidative degradation and biodegradation technique, not only overcome photochemical catalysis degradation-labile defect not when unglazed or illumination is not enough, also overcome general complete biodegradable plastics processed complex, the cost height, the drawback that is difficult for popularization, but existing oxidation-biodegradable plastic is not still broken away from the shortcoming of existing polycomponent degradant additive, as: can't accurate control oxidation inhibitor and the balance of the value volume and range of product of pro-oxidant, the effective active composition distributes in plastics and has bigger uncertainty, therefore can only improve degradation property by increasing consumption
In a word, existing degradative plastics technology exists general technical limitation, any independent method all is difficult to take into account with the essential multiple key element of degradative plastics practicability, as degraded thoroughness, environment friendly, degradation condition universality, technology simplification, cheapization etc.
Summary of the invention
The nano-micelle degradative plastics filler that the purpose of this invention is to provide a kind of environment universality degradative plastics that can under multiple envrionment conditionss such as light, heat and biology/microorganism, degrade, it can promote the degraded of a large amount of general-purpose plastics (mainly comprising polyethylene, polypropylene, polystyrene, polyvinyl chloride, ethylene-vinyl acetate copolymer, ABS resin, polyaniline, polyethylene terephthalate and polybutylene terephthalate etc.) that use on the market, makes its environmentally friendlyization of discarded back.Its way is to add certain amount of nano micella degradative plastics filler in above-mentioned general-purpose plastics raw material, ratio is 0.02-50 (weight percentage), just can obtain at nature (conditions such as sunlight, air, humidity, microorganism) lining, various plastic raw materialss and the goods that can degrade fully.
Therefore one aspect of the present invention provides a kind of nano-micelle filler that can be used for environment universality degradative plastics.
Another aspect of the present invention provides a kind of preparation method of above-mentioned nano-micelle filler.
