Grain, obtains described modified environment-friendly waste and old PE material.
Further, the described method preparing modified environment-friendly waste and old PE material with environmental protection waste and old PE material, wherein said height
Temperature when speed mixer mixes is 50-60 DEG C, and each section of temperature of double screw extruder is 260-270 DEG C.
Compared with prior art, it has the beneficial effect that the present invention
The pollutant on general waste and old PE reclaimed materials surface are broadly divided into two classes, a class be the dust impurity can removed with clear water and
Some are dissolved in the most various salt of material of water, and Equations of The Second Kind is insoluble in the Organic substance of water, and PE waste material is during use before
Organic substance such as oils and fats, all kinds of indissoluble or water-fast organic substance that Multiple components is complicated can be contacted, and these Organic substances are just
It it is the principal element affecting PE waste material performance.The present invention passes through once washing, secondary is washed, be dried, treatment fluid I cleans, processes
Liquid II cleans and the step such as washing and drying more thoroughly removes the pollutant on waste and old PE reclaimed materials surface, makes waste and old PE reclaimed materials
Performance be greatly improved, wherein, water-washing step uses constant temperature to soak, and effectively eliminates waste and old PE reclaimed materials surface
Dust impurity；Secondary water-washing step uses high pressure water cleaning, further removes the dust of waste and old PE reclaimed materials surface residual
Impurity and be dissolved in the material of water；First treatment fluid I cleaning step removes the crude oil fat on waste and old PE reclaimed materials surface, and treatment fluid II is clear
Wash step and more thoroughly remove insoluble organic and the oils and fats on waste and old PE reclaimed materials surface.
During processing waste and old PE material, in order to reach preferable cleaning performance, applicant has prepared treatment fluid I voluntarily
With treatment fluid II, wherein treatment fluid I is by lauric acid, Jojoba oil, ethanol, water, phosphoric acid, glyceryl monostearate and sodium chloride group
Become, in test it has been found that lauric acid, glyceryl monostearate, Jojoba oil are added in ethanol, then hydrous water, its
Cleaning performance can be more a lot of by force than simple lauric acid, and foam is the most less in cleaning process, but Jojoba oil is in temperature
Easily crystallize at PE scraped surface time relatively low, and after adding very small amount phosphoric acid and appropriate sodium chloride in water, then can effectively suppress
Crystallize at PE scraped surface under Jojoba oil low temperature；The preparation for the treatment of fluid II, it is found by the applicant that by anion surfactant nonyl
Base phenol polyethenoxy ether mono sulfosuccinates is dissolved in water, by molten for nonionic surfactant oleic acid Polyethylene Glycol monoesters
In ethanol and anion surfactant lauryl alcohol polyoxyalkylene ether mono succinate sodium sulfonate is dissolved in water compounding after, permissible
Effectively strengthen wettability and soil release performance, and foam seldom need not add defoamer again and carries out froth breaking in cleaning process, but will
Above-mentioned each component mixing aftertreatment fluid has and precipitates appearance on a small quantity, but can play the effect of solubilising after adding ethylene glycol, heavy
Shallow lake can disappear, and the addition of kieselguhr micropowder can shorten the scavenging period for the treatment of fluid, improves cleaning efficiency.
Additionally, the present invention has also carried out blending and modifying, at the prepared waste and old PE of environmental protection to cleaned waste and old PE material
On the basis of material, double (3, the 5-di-tert-butyl-4-hydroxyl benzyl) thioether of interpolation antioxidant, lubricant stearic acid barium, antibacterial shell gather
Sugar graft phenylethene, further improves the performance of environmental protection waste and old PE material, has widened its range of application.Therefore, the present invention is real
Accomplishing environmental protection and energy saving, turn waste into wealth, the waste and old PE material performance prepared equals to completely newly expect.
