Description
Technical field
The present invention relates to plastics arts, particularly relate to a kind of REINFORCED PET and preparation method thereof.
Background technology
Plastic pellet is being commonly called as of plastic grain, and to be plastics carry out storing with work in-process form, transport and the raw material of machine-shaping.Plastics are family macromolecule materials, are that raw material can obtain ethene, propylene, vinylchlorid, vinylbenzene etc. with oil, and the molecule of these materials can react to each other under certain condition and generate the very large compound of molecular weight, i.e. polymer.
The most outstanding character of polypropylene is versatility, and it can be suitable for many working methods and purposes.Its value and versatility mainly from excellent chemical resistance, in the thermoplastics of ancestor in minimum density and the highest fusing point, moderate cost.
Plastics are derivatives of oil, and the market value of plastics depends on the equilibrium of supply and demand in market.The plastics market of China has plastics material of an established trade mark, secondary board material, and reprocessed plastic(s) are formed, and international turn of the market is not very large on domestic impact, and much cheap plastic waste is come from external import, has delayed the impact of International Crude Oil variation on China market.But the ups and downs of international oil price are certainly influential, and plastic waste price is also in ups and downs.
Polyethylene, polypropylene, polyvinyl chloride, polystyrene, our normally used plastics are exactly by above-mentioned four kinds of molecular materials of high score (polyethylene, sound embrittlement during polypropylene film shake; Polyvinyl chloride film is then more soft, without embrittlement sound during shake; Expanded plastic is generally polystyrene, has dense smoke during burning).Begin from the sixties in last century, plastics enter the extensive practical stage, because plastics have lot of advantages: it draws materials easily, cheap, easy to process, quality is light and handy, and therefore plastics one come out, just deeply welcome by the world, it penetrates into different social sectors rapidly, and plastics are made into bowl, cup, bag, basin, bucket, pipe etc., and plastics are listed in one of 20th century greatest invention, the universal of plastics is described as White Revolution.Along with plastics output constantly increases, cost is more and more lower, a large amount of agricultural films that we used, and wrapping plastics bag and disposable plastic tableware are abandoned after a procedure in the environment, are brought very havoc to view and environment.Because plastic packing article is mostly in white, the environmental pollution that they cause is called as white pollution.
PET is high polymers, by ethylene glycol terephthalate generation dehydration condensation.Ethylene glycol terephthalate is by terephthalic acid and ethylene glycol generation esterification gained.PET is oyster white or polymkeric substance that is light yellow, highly crystalline, and surface smoothing is glossy.In wide temperature range, have excellent physical and mechanical properties, life-time service temperature can reach 120 DEG C, and electrical insulating property is excellent, even under high-temperature high-frequency, its electrical property is still better, but corona resistance is poor, creep resistance, resistance to fatigue, rub resistance, dimensional stability are all fine.
PET is divided into fiber polyester chip and non-fiber grade polyester chip.Fiber-grade polyester, for the manufacture of terylene short fiber peacekeeping polyester filament, is the raw material of supply polyster fibre enterprise processing fiber and related products.Terylene is as the maximum kind of output in chemical fibre.Non-fiber level polyester also has the purposes such as bottle class, film, is widely used in the fields such as packing business, electronic apparatus, health care, building, automobile, and wherein packaging is the maximum non-fine application market of polyester, is also the fastest-rising field of PET simultaneously.
