Former is with embodiment 1
The used material of this embodiment is, the polystyrene (PS), Merlon (PC) and acrylonitrile-styrene-butadiene copolymer (ABS) waste or used plastics that reclaim, add 40% long glass fibres enhancing granules of polystyrene simultaneously, in this long glass fiber reinforced ABS particle, the content of long glass fibres is 30wt%.The first rank Planetary Screw Extruder temperature is set from charge door and is set at respectively to outlet: 170 ℃-190 ℃-210 ℃-225 ℃-225 ℃, the extrusion temperature of the second rank single screw extrusion machine is set and is set at respectively from the charge door to the mould: 200 ℃-220 ℃-225 ℃-225 ℃.
In the hopper 2 of the first rank extruder, electric motor starting drives Compulsory feeder used 18 rotations to spring feeding device 8 with mass transport, loose mass transport is gone into the feeding section of Planetary Screw Extruder 7.
Under the rotation of Planetary Screw Extruder 7 is carried, material is compacted gradually, form certain pressure and by the frictional heat of screw rod and machine barrel and shear heat preheating, material arrival planetary-screw section 4 backs are shunted and are rolled into thin slice by the engagement between driving screw 15, minor diameter screw rod 16 and the machine barrel, material continues to be fed forward, in course of conveying, material is subjected to heat and frictional heat and the shear heat that heater transmits, final material is realized good mixing and plasticizing under the effect of driving screw 15 and minor diameter screw rod 16.
The intact material melt of mixing plasticizing enters the charging aperture of the second rank single screw extrusion machine 5 by the first rank Planetary Screw Extruder, 7 discharging openings by jockey 14, and the material melt is realized abundant exhaust in jockey 14.
Material melt through abundant exhaust is introduced the second rank single screw extrusion machine, 5 feeding sections by jockey 14, by the second rank single screw extrusion machine 5 with its further plasticizing, and set up stable melt pressure, at last by mould 17 preparation type waste or used plastics railroad ties.The waste or used plastics railroad tie material mechanical performance of gained is: bending modulus, 1500MPa, bending strength, 20MPa; Vertical compressive strength 30MPa; Transverse compression intensity 10MPa;
The present invention can summarize with other the concrete form without prejudice to spirit of the present invention or principal character.Therefore, no matter from which point, above-mentioned embodiment of the present invention all can only be thought can not limit the present invention to explanation of the present invention, claims have been pointed out scope of the present invention, therefore, suitable with claims of the present invention contain with scope in any change, all should think to be included in the scope of claims.
