Abstract
The invention belongs to the method for the waste plastics recovery utilization being produced acrylonitrile-butadiene-styrene (ABS) copolymer resins (A.B.S).The packing of most of expensive instruments, household electrical appliance etc. all is to come shockproof with Expandable Polystyrene (EPS) (E.P.S) packing material.These packing materials promptly have been abandoned after crossing.The simple machining process of the present invention can make these waste materials be recycled, and produces A.B.S resin or its goods of one of engineering plastics in short supply.
Description
The invention belongs to discarded packing material of Expandable Polystyrene (EPS) (E.P.S) and leftover bits are recycled to produce the method for acrylonitrile-butadiene-styrene (ABS) copolymer resins (A.B.S).
At present, the packing of most in the world instrument, instrument, household electrical appliance and components and parts, workmanship etc. all be with the E.P.S cushion packing reaching the purpose of transportation vibration damping, but these materials have just become refuse after transportation is finished.In addition, also have the factory of many production E.P.S packing materials and E.P.S insulation, cold insulation material also can produce a large amount of limit pin waste materials or the waste material under failed the changeing in process of production, all there are waste materials such as a large amount of abandoned E.P.S lunch boxes in restaurant, railway station etc.
The objective of the invention is to utilize these waste materials to produce A, B.S resin and can further be processed into goods with easy machining process.
Production method step of the present invention is as follows:
Waste disposal, be mixed into cross-linked graft properties-correcting agent.Method has three kinds:
A). latex is handled hybrid system: (also can be broken) after the fragmentation of E.P.S waste material be immersed styrene-butadiene-styrene block copolymer resin (S.B.S), butylbenzene, butyronitrile is along wherein a kind of epoxy glue Ruzhong until four kinds such as fourth.Use the also available chemical demulsifier method of physics method breakdown of emulsion breakdown of emulsion then, mix back dehydration, oven dry also can be dried, airing, air-dry etc.Also the E.P.S waste material directly can be absorbed above-mentioned mixing, the latex after drying it (dry, dry, airing, air-dry all can).
B). the solid materials hybrid system: the E.P.S waste material uses the habitual heating means of industry, heating such as available far infrared, microwave, electric stove wire, hot blast, steam, stack gas, also available coal, charcoal directly, indirect heating, its heating installation can be drum-type also can be the room formula, box or tunnel like.Its heating is temperature required to be 100 to 200 ℃, and in 0.5 to 60 minute, volume can be contracted to 1/2 to 1/20 of original volume to the E.P.S waste material under said temperature, will shrink then and expect after mechanically compress (also can be not compressed) fragmentation.Also can be with waste material without shrinking direct fragmentation.
It is wherein a kind of until five kinds of cross-linked graft properties-correcting agent to add S.B.S resin, butadiene-styrene rubber, butadiene-acrylonitrile rubber, cis-butadiene cement, polycarbonate etc. in broken material, and add-on is 1/100 to 60/100, mixes.
C). mixing method: the E.P.S waste material is mixing even on plastics processing mill together with one to five kind of cross-linked graft properties-correcting agent described in the B method.
2. be mixed into material behind the cross-linked graft properties-correcting agent with various plastics or rubber processing machinery with above-mentioned, for example: extruding machine, injection moulding machine, plastics processing mill, rubber mixing machine, thermocompressor etc. are processed into A.B.S resin or its resin.
The present invention can make the original E.P.S waste material that does not have in a large number to recycle be processed into A.B.S resin in short supply with simple method, turns waste into wealth, and gets final product decontamination, can obtain good economic benefits again.Such as: television cabin can be processed into this method with former teletron waste packing articles in television factory, and cost is very cheap.
Most preferred embodiment: the E.P.S waste material put on the open type plastic purificating set to mix to mould after 15-20 minute with S.B.S resin, butadiene-styrene rubber, butadiene-acrylonitrile rubber, polycarbonate resin together be the A.B.S resin granular material after extruding postcooling, pelletizing with three extruding machines, available then this pellet has been processed into goods such as television cabin.
