Abstract
The invention relates to a separating agent for medical waste aluminium-plastic packaging materials and a preparation method of the separating agent, belongs to a separating solvent for separating the medical waste aluminium-plastic packaging materials and a preparation method of the separating solvent, and mainly aims to solve technical problems that environmental pollution is serious, land resources are wasted, technologies are complex and product recovery rates are low due to adoption of existing aluminium-plastic waste treating methods. The technical scheme is as follows: the separating agent for the medical waste aluminium-plastic packaging materials is prepared from raw materials in percentage by weight as follows: 10%-40% of tetrahydrofuran, 30%-50% of ethyl acetate, 15%-30% of ethyl alcohol and 5%-20% of n-hexane. The preparation method comprises steps as follows: 1) weighing out the raw materials as follows: 10%-40% of the tetrahydrofuran, 30%-50% of the ethyl acetate, 15%-30% of the ethyl alcohol and 5%-20% of the n-hexane; 2) placing the raw materials into a reaction kettle, and evenly stirring the raw materials.
Description
Technical field
The present invention relates to a kind of release agent for medical discarded aluminum-plastic packaged material and preparation method thereof, it belongs to a kind of separation solvent for separating of discarded medical aluminum-plastic packaged material and preparation method thereof.
Background technology
Along with the high speed development of modern industrial technology, the plastic-aluminum technology of packaging industry and product have more and more been widely applied in the every field of people's life, bring great convenience to the life of people, but it is many unfavorable also to bring simultaneously, these packing materials are once finish its mission, just abandoned by artificial, be regarded as house refuse.Especially in pharmaceuticals industry field, it all have employed this packaging material of plastic-aluminum in pharmaceutical packing (tablet, capsule, suppository etc.).Use these aluminum-plastic packaged materials directly to define " white garbage ", both contaminated environment, cause again the great wasting of resources.For alleviating the pollution of environment and find resource from rubbish, make it recycle, at present, following several processing method mainly contained for plastic-aluminum this " white garbage ":
1, landfill.Landfill operation is that China processes the topmost method of domestic waste at present.But all contain the heavy metal additive such as Pb (lead), Gd (cadmium) in the PVC material of the overwhelming majority, if be landfilled, the severe contamination to soil and water source can be caused.In addition, because this kind of white garbage quality is bulk, landfill can seriously take up an area.Therefore, landfill method also exists the serious defect with wasting soil of contaminated environment.
2, burn.In some areas, use the method for burning plastic-aluminum, obtain aluminium, thus obtain certain economic well-being of workers and staff.This method in combustion, can produce the pollutant of all how much amount and discharge a large amount of toxic gas HCl, CO and deadly poisonous compound---dioxin, easily causing air pollution and haze.
3, aluminum-plastic separation.Existing people have carried out the research work be separated plastic-aluminum at present, also plastic-aluminum can be separated, but its separating technology is complicated, detached job environment is poor, product recovery rate is low, easily cause the problems such as secondary environmental pollution not to be well solved.
Summary of the invention
The technical problem that contaminated environment is serious, waste land resource, complex process and product recovery rate is low that the method that the object of the invention is to solve existing process plastic-aluminum discarded object exists, provides a kind of free from environmental pollution, technique is simple and product recovery rate is high release agent for medical discarded aluminum-plastic packaged material and preparation method thereof.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
For a release agent for medical discarded aluminum-plastic packaged material, it is made up of the raw material of following weight percentage: oxolane 10%-40%, ethyl acetate 30%-50%, ethanol 15%-30% and n-hexane 5%-20%.
Prepare a method for the above-mentioned release agent for medical discarded aluminum-plastic packaged material, it comprises the following steps:
1) raw material is taken by following percentage by weight: oxolane 10%-40%, ethyl acetate 30%-50%, ethanol 15%-30% and n-hexane 5%-20%,
2) above-mentioned raw materials is put into reactor to stir.
Owing to present invention employs technique scheme, the secondary pollution environment that the method solving existing process plastic-aluminum discarded object exists, the technical problem that waste land resource, complex process and product recovery rate is low.Therefore, compared with background technology, the present invention has free from environmental pollution, that technique is simple and product recovery rate is high advantage.
The present invention proves by experiment: this separation solvent can complete aluminum-plastic separation process in the short period of time, and product recovery rate reaches 99.96%, and the color of PVC and aluminium foil and physical aspect do not change substantially, ensure that the quality reclaiming product.Experimental result sees the following form:
| Sample mass | Aluminium quality | PVC quality | Overall recovery | Temperature | Disengaging time |
| 10g | 1.299g | 8.696g | 99.96％ | 22℃ | 40min |
