Description
Technical field
The invention belongs to technical field of polymer materials, relate to a kind of preparation method of titanium dioxide iron stearate kaolin light-Re oxygen degradable laminating polyethylene film.
Background technology
Plastics have the advantages such as stability is strong, light weight, production cost are low, thus deeply look at by the parent of people.Plastics industry obtains fast development in recent decades, and the use of a large amount of plastics especially Phthalates, brings great convenience to the life of the mankind.But, due to the chemical stability of general-purpose plastics (PE, PS, PVC etc.) itself, when steady in a long-termly in the environment existing after its abandoned, cause the accumulation in the environment of a large amount of plastic refuse, serious harm is brought, as the problem such as white pollution, agriculture white cancer to environment.
Plastics common in life have daily plastic goods, agricultural plastic product etc., wherein Phthalates, because recovery value is low, after using usually abandoned in environment.Therefore, in the street in city, in the both sides of highway and railway, in the tourist district that scene is beautiful, in the rivers,lakes and seas of Source of life etc., nearly all can see their figure.Here it is " white pollution " often said.Except " white pollution ", they also also exist potential harm to ecotope.Such as: 1) to the harm of agricultural: due to gas tightness and the water-repellancy of plastics, after together with mixing with soil, the absorption of farm crop to nutrient, moisture will be affected, thus cause doing crop failure; 2) to the threat of animal survival: animal is when engulfing the plastic package foods abandoned by the mankind, and plastic packaging film is often engulfed together, being difficult to digestion by plastics long-time delay in the stomach of animal of engulfing by mistake, finally causing animal dead; 3) affect the sustainable use in soil: plastic quality is light, volume is large, with garbage loading embeading in soil, the centuries all can not change, and has a strong impact on Soil structure, and long-term land occupation resource.
Along with becoming increasingly conspicuous of environmental problem, and human environment protection consciousness improve constantly, the process problem of plastic refuse, has become the focus of international community's extensive concern.The way addressed this problem at present mainly contains burning method, landfill method and recycling etc.Burning method is one of main method for the treatment of of urban garbage, and plastic refuse has high fuel value, can discharge a large amount of heats during burning, therefore has higher burning and is worth.In addition, this treatment process also has that cost is low, efficiency advantages of higher.Therefore, the good method of disposal of plastic waste had once once been considered to be.But this method also also exists many problems and is constantly subject to the query of people.Major cause is that plastic refuse can inevitably produce the objectionable impuritiess such as sulfurous gas, dioxin in burning process, wherein dioxin objectionable impurities belongs to generally acknowledged one-level carcinogens, in addition, the great amount of carbon dioxide of burning release can cause Greenhouse effect again, and therefore this treatment process can bring serious secondary pollution to environment.In recent years, many countries start the cry occurring opposition the method in the world, and China's waste incineration method is also starting to enter the atrophy phase.
Landfill method is the method that domestic and international treating refuse the most extensively adopts, is mainly divided into two classes at present: traditional landfill method and sanitary landfill method.Tradition landfill method namely under field conditions (factors), by direct for rubbish landfill in underground.This treatment process is simple, is still the main path of many national disposal of plastic waste so far.But this treatment process, there is no consideration environmental protection problem, various potential threat is caused to ecotope.Sanitary landfill method is improving constantly along with Landfill, grow up gradually a kind of consider landfill after rubbish thing on the method for the impact of environment.Such as, before landfill, certain process is carried out to rubbish, addressing is carried out to landfill, and carry out the process such as antiseep.But at present because Landfill is low, the problems such as management of water adjustment, are difficult to really accomplish sanitary landfill in the process of the process of reality.In a word, landfill method does not process rubbish in essence, and it has just transferred to another one place plastic refuse from a place.And the landfill of rubbish occupies a large amount of land resources, therefore, landfill method can not realize the final process to plastic refuse.
Recycling is that the plastic refuse reclaimed is passed through the operations such as classification, fragmentation, cleaning, then by the processing of special granulating equipment, thus obtains the master batch of the plastics of regeneration, makes resource obtain cycling and reutilization.Compared with first two method, this treatment process relatively economical, environmental protection.Therefore, this method is one of Main Means of disposal of plastic waste.But waste plastic is usual and other solid waste are mixed in together, there is a lot of difficulty with dealing with in actual recovered.Phthalates is worth without recycling.In general, the recycling degree of plastic refuse is low, only has seldom part to be recovered utilization, and complex disposal process, the solution plastic refuse pollution problem that therefore recycling method can not be final.
Above several method is still the common method of numerous national disposal of plastic waste at present, and along with becoming increasingly conspicuous of respective Problems existing, above-mentioned several method can not meet the requirement of the mankind to environment protection.Fundamentally solving plastic refuse pollution problem, seek new Resolving probiems approach, is that the mankind urgently wish to realize.After degradable plastics is discarded, some factor in environment can be utilized to degrade, so plastic refuse accumulation in the environment can be reduced, and then fundamentally solve plastic refuse to the pollution problem of environment.Therefore, develop degradable plastics and become the final approach solving plastic refuse pollution problem.
The terminology standard ASTMD883-92 of the relevant plastics passed through according to American Society for testing and materials (ASTM) is to the definition of degradable plastics: degradable plastics namely under certain environmental conditions, its chemical structure generation considerable change, and the plastics of its material performance variation can be measured by the testing method of standard.Usual degradable plastics possesses following characteristics: under the natural environmental condition impacts such as sunlight, oxygen, microorganism, and significantly change occurs the outward appearance of plastics; Mechanical property occurs significantly to reduce; Chemical structure changes, and it is medium that oxygenatedchemicals is introduced in plastics.Only have when plastic polymer there occurs above change, after the molecular weight of self is reduced and producing small molecules oxygenatedchemicals, could by the microbial decomposition of occurring in nature.Degradable plastics is expected to the pollution problem solving plastic refuse, has therefore become the focus of current research.The more degradable plastics of current report mainly contains photodegradable plastics, biodegradable plastic and photo-biodegradable plastic etc.
