Abstract
The invention relates to a method for recovering a PC waste material, which comprises the following steps: recovering a plastic part of PC components; cleaning; washing; cooling and crushing; washingagain; dewatering and drying; and adding an additive, extruding and forming; the steps of additive adding, extruding and forming concretely comprise the following processes: taking an extruding machine as main equipment, then matching with auxiliary equipment added with the additive and adding 2-20% of PTFE or 1-5% of molybdenum disulphide and the balance of PC plastics at the temperature of 240-300 DEG C according to the weight percent. By the invention, modified engineering plastics with wear-resistant property can be obtained.
Description
Technical field
The present invention relates to plastics recovery method, relate in particular to the recovery method of PC waste material.
Background technology
Current, the plastics industry is key pillars of the national economy, and its proportion in four big Industrial materials cement, iron and steel, timber, plastics is increasing.The raw material of plastics is mainly derived from fossil oils such as non-renewable oil, coal, Sweet natural gas, and along with the growing tension of resource, the reprocessed plastic(s) of recovery then are the inevitable approach of plastics industry Sustainable development.
And the salvage material of present more mixed and disorderly and many kinds of doing the great majority employing of modifying plastics recovery producer, just simple recovery, cleaning, heating are merged in treating processes, the modified plastics poor performance that recovery obtains can not satisfy the requirement that use in market.
Summary of the invention
The present invention is directed to the above-mentioned defective of prior art, the recovery method of PC waste material is provided, make to reclaim to obtain having the wear resisting property modified engineered plastic.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The recovery method of PC waste material is characterized in that, comprise the steps: to reclaim the plastic parts of PC composition-＞cleaning-＞clean-＞cooling is broken-＞clean again-＞dewatered drying-＞add the additive extrusion moulding; Wherein adding the additive extrusion moulding specifically comprises, be that major equipment is equipped with the auxiliary facility that adds additive again adds the PTFE of 2%-20% or the molybdenumdisulphide of 1%-5% by weight percentage under the temperature of 240 ℃-300 ℃ of temperature with the forcing machine, surplus is the PC plastic cement.
Preferably, the melt index according to predetermined plastic parts before adding the additive extrusion moulding divides into groups to plastic parts, and the plastic parts of choosing on the same group adds the additive extrusion moulding.
As can be seen from the above technical solutions, the present invention utilizes that the source is abundant, recovery plastics with low cost are the recovery technology of raw material through specialty, not only have and to reclaim the chemical raw material that to degrade fully, and the material that recovery obtains has the wear resisting property modified engineered plastic, reach environmental protection and scientific and technological perfect combination, comply with the environmental protection policy of national energy-saving and emission-reduction.
Embodiment
The present invention is further detailed explanation below in conjunction with embodiment.
The old plastic parts that reclaims the special-purpose bucket of PC five gallon bottle that domestic and international water factory eliminates usefulness and all PC compositions of eliminating of electronic enterprises through the cleaning → dewatered drying of cleaning → cleanings → cooling fragmentation → again → pack → according to the melt index of the PC that is scheduled to obtain to plastic parts PC interpolation additive extrusion moulding on the same group → pack → the be applied to relevant industries of dividing into groups → choose.
Wherein in the cleaning link, take manually to hang one by one except that the product surface part of painting with blade, finish through professional quality personnel inspection, through being with water-cooled crusher fragmentation, the broken intact drum-type moisturizing washing machine that directly enters is after five to ten minutes washing then, wait that the water that washs out is limpid, change raw material over to clean water basin and clean again once, change the drying machine that can dewater then over to, at last packing.
The broken starting material that finish are cleaned in cleaning, extruding machine through 240 to 300 degree celsius temperature by two Luo bars is major equipment, mix the auxiliary facility that adds additive again, add the PTFE of 2%-20% or the molybdenumdisulphide of 1%-5% by weight percentage, obtain with PC be base material have a wear resisting property modified engineered plastic, surplus is the PC plastic cement.
Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail this creation, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of this creation, all should be included in the claim of this case suitable first Chen Ming.
Claims (2)
1, the recovery method of PC waste material is characterized in that, comprises the steps: to reclaim the plastic parts-cleaning-cleaning-cooling fragmentation-cleaning-dewatered drying-interpolation additive extrusion moulding again of PC composition; Wherein adding the additive extrusion moulding specifically comprises, be that major equipment is equipped with the auxiliary facility that adds additive again adds the PTFE of 2%-20% or the molybdenumdisulphide of 1%-5% by weight percentage under the temperature of 240 ℃-300 ℃ of temperature with the forcing machine, surplus is the PC plastic cement.
2, the recovery method of PC waste material according to claim 1 is characterized in that: the melt index according to predetermined plastic parts before adding the additive extrusion moulding divides into groups to plastic parts, and the plastic parts of choosing on the same group adds the additive extrusion moulding.
