Description
Technical field
The present invention relates to a kind of environmental-friendly plastic additive and preparation method thereof, belong to chemical field.
Background technology
As everyone knows; Fast development along with twentieth century petrochemical industry after the middle period; Plastic material has become most important material in people's daily life; Like the shell of plastics bag, plastic cup, most of electrical home appliances, footwear material, tableware, raincoat, plastic sheeting for farm use, packing film, container, stationery, leisure goods, household supplies etc. all is plastics, so plastic material is real inseparable with daily life, but the shortcoming of plastic material maximum is the processing of its waste; If use the mode of burying, its characteristic of not changing in thousand will make decline to a great extent the working life of landfill; If the use incineration process then can produce dioxin, HCN, HF, CO, SO because of plastics after burning
2Deng toxic gas, not only can make the air quality variation of incinerator periphery or cause Greenhouse effect, point out that more on evidence it possibly cause serious HUMAN HEALTH problems such as the pregnant woman miscarries, lung cancer; In recent years, because the air pollution problems inherent that incinerator causes causes many serious fight incidents, the difficulty and the crisis of the offal treatment of outstanding more plastics are badly in need of solving.At present, the emission standard of incineration process toxic gas often adopts the ABD-0031 test specification to carry out, and it was a standard with 4 minutes combustion times; Its code requirement is that the emission concentration of HF must be less than 100ppm; The emission concentration of HCl must be less than 150ppm, and the emission concentration of HCN must be less than 150ppm, SO
2Emission concentration must be less than 100ppm, NO
XEmission concentration must be less than 100ppm, the emission concentration of CO must be less than 3500ppm.Become people's problem of needs solution day by day so satisfy the plastics of above incineration standard.
Summary of the invention
The present invention's one purpose provides a kind of environmental-friendly plastic additive, and when this additive was added to plastics, these plastics had eco-friendly advantage.
Another purpose of the present invention provides the preparation method of this environmental-friendly plastic additive.
One aspect of the present invention provides a kind of environmental-friendly plastic additive, and this additive contains 1) new LDPE (film grade), 2) nano-calcium carbonate, 3) sarin resin, 4) high density polyethylene(HDPE), 5) lubricant, 6) modified starch, 7) low thermal oxidation agent, 8) static inhibitor, 9) microbial preparation, 10) Vestolen PP 7052 and 11) glycerine or Ucar 35.Described additive can be used for any plastics; Like the shell of plastics bag, plastic cup, electrical home appliances, footwear material, tableware, raincoat, plastic sheeting for farm use, packing film, container, stationery etc.; And make these plastics have eco-friendly advantage; That is: the emission standard after the burning adopts the ABD-0031 test specification to carry out, and various exhaust gas discharging concentration are all within standard; After burying in soil, the plastics that contain above additive can in 1 year, degrade.
Preferably, described additive contains the microbial preparation of its gross weight 1-5%.
Preferably, described microbial preparation is citrobacter freundii (latin name Citrobacterfreundii), stenotrophomonas maltophilia (latin name Stenotrophomonas maltophilia), dead rice sprout spore bacillus (latin name Bacillus vallismortis), acinetobacter calcoaceticus (latin name Acinetobacter calcoaceticus), pseudomonas (latin name Pseudomonassp.), Pseudomonas oleovorans (latin name Pseudomonas oleovorans), Erwinia (latin name Erwinia rhapontici), bacillus pumilis (latin name Curtobacteriumcitreum), Bacillus subtilus (latin name Bacillus subtilis) and Bacillus licheniformis (latin name Bacillus licheniformis).The microbial preparation of being made up of above 10 kinds of bacterial classifications is available from the limited commercial firm of Japanese CORONA, and the said firm is positioned at Tokyo, Japan three hawk cities.After the environmental-friendly plastic additive that contains microbial preparation adds plastics, can be so that the depleted plastics when in soil, burying, ferment when suitable sunlight, humidity, temperature.This microbial preparation can play the effect of eliminating the waste plastic goods with after natural wild bacterium combines, and when burning, plastics are easy to incinerate.
