Abstract
The invention discloses a method for preparing recycled plastics. The method comprises the following steps: (A) cleaning wastes: putting plastic wastes and polyurethane wastes into a pickling tank, soaking for 2 days, then, fishing out and air-drying; (B) crushing the air-dried wastes, heating to melt the wastes, adding ABS (Acrylonitrile-Butadiene-Styrene copolymer), chloropropane, urea, calcium stearate, a degradation agent, an antioxidant and a plasticizer, and enabling the raw material to be viscous; (C) extruding the viscous raw material obtained in the step (B) with an extruder, so as to form strips, arranging a cutter in front of the extruder, cutting the strips once every 1mm, so as to form small strips, and enabling the cut small strips to fall onto a water-cooled conveying belt; (D) cooling the small strips by the water-cooled conveying belt during conveying, and bagging until the small strips are conveyed to the tail end, thereby obtaining recycled plastic granules, wherein the melting temperature is 300-600 DEG C, and the conveying degree of the water-cooled conveying belt is 8-10 meters. The method is simple in preparation, convenient in use and high in waste utilization ratio.
Description
Technical field
The present invention relates to plastic raw materials technical field.Particularly relate to a kind of manufacture method of regenerated plastics.
Background technology
In daily life, use various plastic products, these plastic products, after discarding, are not easily degraded, are arbitrarily abandoned generation pollution problem, so the regeneration for these discarded plastic products is the technical issues that need to address.At present, comprise the application of a series of plastics such as polyethylene, polypropylene, polyvinyl chloride, polystyrene and polyester, throughout the various aspects of industrial and agricultural production and people's daily life.But along with extensive, a large amount of application of plastic casing plastic products, various waste plastics and discarded plastic products also produce in a large number, and these waste plastics are difficult to degraded under natural environment, can only process by burning or burying.But, when burning, a lot of pernicious gases such as hydrogen chloride can be produced due to high-temp combustion, great harm caused to environment.And bury in process, the noxious material in plastics can ooze out, and causes secondary pollution, affects the value in soil.Therefore, need to adopt new technique to the manufacture method of the process and regeneration that obtain waste plastics.
Summary of the invention:
The object of the invention is to, the problem of plastic reclaimed underutilization in a kind of prior art is provided, provide a kind of proportioning simple, easy to use, the manufacture method of a kind of regenerated plastics that waste utilization rate is high.
For solving the problems of the technologies described above, the invention provides a kind of regenerated plastics, wherein, comprising following component:
Plastic waste 80-120 part, polyurethane waste material 20-40 part, ABS10-20 part, chloropropane 5-10 part, urea 3-8 part, calcium stearate 1-3 part, degradation agent 0.5-1 part, antioxidant 0.5-1 part, plasticizer 0.5-1 part.
Or, comprise following component: plastic waste 80-100 part, polyurethane waste material 20-30 part, ABS10-15 part, chloropropane 5-8 part, urea 3-7 part, calcium stearate 1-2 part, degradation agent 0.5-0.8 part, antioxidant 0.5-0.8 part, plasticizer 0.5-0.8 part.
Or, comprise following component: plastic waste 100-120 part, polyurethane waste material 30-40 part, ABS15-20 part, chloropropane 8-10 part, urea 5-8 part, calcium stearate 2-3 part, degradation agent 0.8-1 part, antioxidant 0.8-1 part, plasticizer 0.8-1 part.
The preparation method of above-mentioned material
The cleaning of A, waste material: plastic waste and polyurethane waste material are put in pickling tube and soak 2 days, then pull out, dry.
B, the fertilizer pulverizing of will dry, after melting of heating, add ABS, chloropropane, urea, calcium stearate, degradation agent, antioxidant, plasticizer, make it become thick,
C, use extruder, raw material thick in step B is extruded slivering, and extruder front arranges cutting knife, and every 1mm cutting once, is little strip after cutting and drops on water-cooled conveyer belt,
The cooling of little bar given by D, water-cooled conveyer belt in transmitting procedure, to end, pack to obtain recycled plastic granules.
The temperature of described melting is 300-600 degree Celsius, and the transport degree of water-cooled conveyer belt is 8-10 rice
Advantage of the present invention is: the problem of plastic reclaimed underutilization in prior art, by plastics fertilizer and polyurethane waste material mixture, by plasticizer and degradation agent acting in conjunction, obtain new reworked material, the simple use plastic waste that utilization rate is more traditional improves 18.4%.
Detailed description of the invention:
Example 1:
Plastic waste 80 parts, polyurethane waste material 20 parts, ABS10 part, chloropropane 5 parts, 3 parts, urea, calcium stearate 1 part, degradation agent 0.5 part, antioxidant 0.5 part, 0.5 part, plasticizer.
Example 2
Plastic waste 100 parts, polyurethane waste material 30 parts, ABS15 part, chloropropane 8 parts, 7 parts, urea, calcium stearate 2 parts, degradation agent 0.8 part, antioxidant 0.8 part, 0.8 part, plasticizer.
Example 3
Plastic waste 120 parts, polyurethane waste material 40 parts, ABS20 part, chloropropane 10 parts, 8 parts, urea, calcium stearate 3 parts, degradation agent 1 part, antioxidant 1 part, 1 part, plasticizer.
The preparation method of above-mentioned material
The cleaning of waste material: plastic waste and polyurethane waste material are put in pickling tube and soak 2 days, then pull out, dry.
The fertilizer dried is pulverized, after melting of heating, adds ABS, chloropropane, urea, calcium stearate, degradation agent, antioxidant, plasticizer, make it become thick, use extruder,
Raw material thick in step B is extruded slivering, and extruder front arranges cutting knife, and every 1mm cutting once, is little strip after cutting and drops on water-cooled conveyer belt,
The cooling of little bar given by water-cooled conveyer belt in transmitting procedure, to end, pack to obtain recycled plastic granules.
Advantage of the present invention is: the problem of plastic reclaimed underutilization in prior art, by plastics fertilizer and polyurethane waste material mixture, by plasticizer and degradation agent acting in conjunction, obtain new reworked material, the simple use plastic waste that utilization rate is more traditional improves 18.4%.
