Abstract
The invention discloses a totally degradable plastic film. The raw materials of the plastic film comprise high-density polyethylene or low-density polyethylene, middle-density polyethylene particles and fillers, adding with TDPATM additives which are produced by EPT company, Canada, and recovery connatural waste recycled plastic particles. The raw material and the weight ratio of the plastic film are 40 to 70 percent of the polyethylene particles, 2 to 30 percent of the TDPATM additives, 2 to 30 percent of the additives and 2 to 30 percent of the waste recycled plastic particles. 1 to 8 percent colored polyethylene particles are added in the raw materials to be made into colored film. The raw materials are mixed in proportion according to the production requirements, are added in an inflation film manufacturing machine to be heated up to the prescribed temperature and then the totally degradable plastic film is produced. The totally degradable plastic film has simple prescription, easy fabrication, few process steps, short flow and few used equipment with only the inflation film manufacturing machine. The thickness of the totally degradable plastic film can reach as thin as 0.02, with the middle; wherein, 0.025 thickness film has 33 MPa of longitudinal tension degree and 25 MPa of transverse tension degree of the mechanical properties, 260 percent of longitudinal tensile stretch and 620 percent of transverse tensile stretch and 3 months to 2 years of adjustable degradation time.
Description
Technical field
The present invention relates to a kind of plastics, particularly a kind of complete-degradable plastic film.
Background technology
Plastics are as a kind of general material of having many uses, in big convenience in people's life, its nondecomposable characteristic has also caused serious environmental problem.Therefore research and production degredation plastic goods have caused great attention in the world.People begin utilizing production degradable plasticss such as starch and vegetable-protein to carry out a large amount of research and development utilizations, as: Chinese patent application number: 200410065649.8, title: a kind of high starch degradable plastic film, obtained great success, but because of reasons such as the thickness of production technique, production cost, product and tensile strength also do not obtain promoting, it is used and also has been subjected to considerable restraint.
Summary of the invention
Technical problem to be solved by this invention provides a kind of thin thickness, intensity is big and the simple complete-degradable plastic film of production technique.
The technical solution used in the present invention is:
This complete-degradable plastic film, its raw material comprises polyethylene particle and weighting agent, and add an amount of TDPATM additive and waste and old reprocessed plastic(s) particle, routinely explained hereafter.The raw material of this plastics film and weight proportion are:
Polyethylene particle 40-70%, TDPATM additive 2-30%, weighting agent 2-30%, waste and old reprocessed plastic(s) particle 2-30%.
As a kind of optimal way of the present invention, the raw material of this plastics film and weight proportion are:
Polyethylene particle 50-60%, TDPA
TMAdditive 4-25%, weighting agent 4-20%, waste and old reprocessed plastic(s) particle 4-25%.
Described TDPA
TMAdditive is that Canadian EPT company produces, and TDP (Totally DegradablePlastics) is the abbreviation of complete-degradable plastic goods.
Described polyethylene particle means high density polyethylene(HDPE) particle or new LDPE (film grade) particle and medium-density polyethylene particle.
Described waste and old reprocessed plastic(s) particle be reclaim with the connatural waste and old reprocessed plastic(s) particle of described polyethylene particle.
Described weighting agent is a lime carbonate.
In order to make the plastics film that to degrade fully of band color, can in raw material, add 1-8% band color polyethylene particle.
Above-mentioned raw materials is mixed in proportion according to producing needs, and the adding inflation film manufacturing machine is warmed up to specified temperature and can produces the plastics film that can degrade fully.
A kind of complete-degradable plastic film prescription disclosed in this invention is characterized in 1, adds the effect that medium-density polyethylene plays the reinforced plastics film strength.2, add TDPA
TMAdditive mainly is to make the plastics film that can degrade fully, and can guarantee in the validity period of product, not change its quality, and after validity period, can carry out the decomposition of carbon and hydrogen atom by any effect of sunlight, heat energy or pulling force, under action of microorganisms, discharge CO2 and water, dissolve in the Nature and in decomposition course, do not discharge any objectionable impurities, also can adopt treatment processs such as recovery, compost, burning.3, add to reclaim the waste or used plastics product grain the same with its character, can utilization of waste material, play reduction viscosity in process of production simultaneously, stablize the effect that inflation film manufacturing machine moves.
The present invention fills a prescription simply, makes easily, and processing step is few, and flow process is short, and the equipment less investment mainly is an inflation film manufacturing machine etc.The present invention can produce thin thickness, complete-degradable plastic film that intensity is big, the film of its thickness the thinnest 0.02, and wherein thickness is that its mechanical property of film of 0.025 is as follows:
1, degree of drawing: vertical horizontal 25Mpa of 33MPa;
2, elongation: vertical 260% horizontal 620%;
3, degradation time: 3 months to 2 years adjustable.
With documents Chinese patent application number: 200410065649.8, title: the degree of drawing 16Mpa that the patent document of " a kind of high starch degradable plastic film " is announced, the mechanical property of elongation 550% improve, and be also thinner than the thickness 0.05mm that announces.
