Abstract
The invention discloses a method for preparing toughness modified plastic granules. The method comprises the following steps: (A) cleaning wastes: putting plastic wastes and precipitated barium sulfate, which is subjected to coupling treatment, 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 saponified EVA (Ethylene Vinylacetate Copolymer), chlorinated butadiene/styrene block copolymer, PP (Polypropylene), sorbitol, a degradation agent, an antioxidant and antimony trioxide, 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 the toughness modified 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 plastic grain of toughness modification.
Background technology
In daily life, use various plastics, these plastics, after discarding, are not easily degraded, are arbitrarily abandoned generation pollution problem, so the regeneration for these discarded plastics 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 all respects of industrial and agricultural production and people's daily life.But along with extensive, a large amount of application of plastics casing plastics, various plastic waste and discarded plastics also produce in a large number, and these plastic waste are difficult to degraded under physical environment, can only process by burning or burying.But, when burning, a lot of obnoxious flavoures such as hydrogenchloride can be produced due to high-temp combustion, great harm caused to environment.And bury in process, the toxic substance in plastics can ooze out, and causes secondary pollution, affects the utility value in soil.Therefore, need to adopt new technique to the manufacture method of the process and regeneration that obtain plastic waste.
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 the plastic grain of a kind of toughness modification that waste utilization rate is high.
For solving the problems of the technologies described above, the invention provides a kind of plastic grain of toughness modification, wherein, comprising following component:
Plastic waste 80-120 part, process white 20-40 part of coupling processing, saponification EVA10-20 part, chlorination Butadiene/Styrene segmented copolymer 5-10 part, PP3-8 part, sorbyl alcohol 1-3 part, degradation agents 0.5-1 part, antioxidant 0.5-1 part, antimonous oxide 0.5-1 part.
Or, comprise following component: plastic waste 80-100 part, process white 20-30 part of coupling processing, saponification EVA10-15 part, chlorination Butadiene/Styrene segmented copolymer 5-8 part, PP3-7 part, sorbyl alcohol 1-2 part, degradation agents 0.5-0.8 part, antioxidant 0.5-0.8 part, antimonous oxide 0.5-0.8 part.
Or, comprise following component: plastic waste 100-120 part, process white 30-40 part of coupling processing, saponification EVA15-20 part, chlorination Butadiene/Styrene segmented copolymer 8-10 part, PP5-8 part, sorbyl alcohol 2-3 part, degradation agents 0.8-1 part, antioxidant 0.8-1 part, antimonous oxide 0.8-1 part.
The preparation method of above-mentioned materials
The cleaning of A, waste material: the process white of plastic waste and coupling processing is put in pickling tub and soaks 2 days, then pull out, dry.
B, the fertilizer pulverizing of will dry, after melting of heating, add saponification EVA, chlorination Butadiene/Styrene segmented copolymer, PP, sorbyl alcohol, degradation agents, antioxidant, antimonous oxide, make it become thick,
C, use forcing machine, raw material thick in step B is extruded slivering, and forcing machine front arranges cutting knife, and every 1mm cutting once, is little strip after cutting and drops on water-cooled travelling belt,
The cooling of little bar given by D, water-cooled travelling belt in transmitting procedure, packs to obtain the plastic grain of toughness modification to end.
The temperature of described melting is 300-600 degree Celsius, and the transport degree of water-cooled travelling belt is 8-10 rice
Advantage of the present invention is: the problem of plastic reclaimed underutilization in prior art, by the process white mixture of plastics fertilizer and coupling processing, by antimonous oxide and degradation agents acting in conjunction, obtain new reworked material, the simple use plastic waste that utilization ratio is more traditional improves 16.0%, melting index 2.6g/10min.。
