Description
Technical field：
The present invention relates to resource regeneration technical fields, and in particular to a kind of to utilize polyethylene waste material green production environmental-protection
The method of net.
Background technology：
Since nineteen thirty modern plastics industry is formed, by the rapid development of more than 80 years, plastics industry had become gently
The mainstay of industry.While the extensive use of plastic product, huge plastic pollution is also produced, to the ecology in the whole world
Environment causes great destruction.Processing method to waste plastic garbage is mainly landfill disposal and burning disposal, however is filled
Processing increases land resource pressure since its occupied space is larger, simultaneously because useless modeling is difficult to degrade, it is serious to hamper water
Infiltration and underground water circulation, secondly additive in useless modeling can also be to soil reclamation secondary pollution.Burning disposal is due to burning
CO, polycyclic aromatic compound and the heavy metal of generation can together discharge with flue dust and incineration residue and environment caused very
Big pollution.With the progress of science and technology, start to occur carrying out regenerating and modifying to waste plastic using plastic reclaimed machinery,
Really resources circulation is realized in consciousness.
But, impurity content poor using the modified plastics of prior art production and its physics and chemistry and mechanical performance of product
Higher, poor toughness is frangible, and durability is undesirable, affects the utilization of modified plastics and its use of product.
Invention content：
It is good that the technical problems to be solved by the invention are to provide a kind of antistatic property, and elasticity is good, fire-retardant, ageing-resistant
Protection network preparation method.
The technical problems to be solved by the invention are realized using following technical solution：
A kind of method using polyethylene waste material green production environmental-protection net, step are as follows：
S1. waste polyethylene is crushed, is then fed into decomposing pool immersion, time control was at 20-80 hours, temperature
30-55℃；Since waste polyethylene surface impurity content is more, it is necessary to carry out immersion removal of impurities；And tradition is carried out clearly by cleaning equipment
It washes, the slightly solubility impurity on surface can not be removed, it is unfavorable to the raising of final product quality；
S2. the waste polyethylene after immersion is put into reaction kettle together with the clear water of immersion, temperature in the kettle control exists
60-85 DEG C, kettle pressure 3-10MPa is kept for 10-20 minutes；Purpose is that the slightly solubility substance of polyethylene surface is made to be detached from polyethylene,
This method is inventor according to practical working experience gained, weight ratio experiment by parameter selection many times and many times
The one group of most effective data area obtained afterwards thoroughly solves the contaminant problems of waste polyethylene；
S3. the waste polyethylene in reaction kettle is poured out, and dried, be then fed into dry setting and processing is dried；
Above-mentioned drying is carried out in vacuum cold wind drier, 45-55 DEG C of drying temperature；Conventional method is straight after drying
Granulation is connect, comminutor thus can be made to generate a large amount of flue gases, the environment in workshop is impacted；And the application passes through cold air drying
Afterwards, solve the problems, such as that flue gas diffuses in granulation process, smoke yields are few, no bad smell；
S4. dried waste polyethylene is granulated, obtains regenerated polythene particle；The particle impurity content is low, product
Matter is good；
S5. regenerated polythene particle in mass ratio：Pentaerythritol stearate：Amino resins：Antistatic agent=100：2~
5：5：0.3~2 ratio carries out dispensing, in stirrer for mixing, obtains mixture；
S6. mixture is subjected to pressurization extrusion, filtering, is sprayed from spinning head, dynamic analysis of spinning passes through the air of 10~50mm
Enter acetone or magnetized water coagulating bath solidification forming after layer, Regenerated Polyester Fibres are made；
S7. Regenerated Polyester Fibres are woven, you can obtain finished product protection network.
