Abstract
The invention discloses a toughness-modified plastic granule which comprises 80-120 parts of plastic waste, 20-40 parts of coupling treated precipitated baryte, 10-20 parts of saponified EVA (ethylene-vinyl acetate), 5-10 parts of chlorinated butadiene/styrene block copolymer, 3-8 parts of PP (polypropylene), 1-3 parts of sorbitol, 0.5-1 part of degradation agent, 0.5-1 part of antioxidant and 0.5-1 part of antimony trioxide. The toughness-modified plastic granule solves the problem of insufficient reutilization of plastics in the prior art; the plastic fertilizer and coupling treated precipitated baryte are compounded under the combined actions of the antimony trioxide and degradation agent to obtain the new reclaimed material. Compared with the traditional simple use of plastic waste, the utilization ratio is enhanced by 16.0%, and the melt index is 2.6g/10 minutes.
Description
Technical field
The present invention relates to plastic raw materials technical field.Particularly relate to a kind 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 obtain process and the regeneration of 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 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 particle of toughness modification to end.
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.。
embodiment:
Example 1:
Plastic waste 80 parts, the process white of coupling processing 20 parts, saponification EVA10 part, chlorination Butadiene/Styrene segmented copolymer 5 parts, PP3 part, sorbyl alcohol 1 part, degradation agents 0.5 part, antioxidant 0.5 part, antimonous oxide 0.5 part.
Example 2
Plastic waste 100 parts, the process white of coupling processing 30 parts, saponification EVA15 part, chlorination Butadiene/Styrene segmented copolymer 8 parts, PP7 part, sorbyl alcohol 2 parts, degradation agents 0.8 part, antioxidant 0.8 part, antimonous oxide 0.8 part.
Example 3
Plastic waste 120 parts, the process white of coupling processing 40 parts, saponification EVA20 part, chlorination Butadiene/Styrene segmented copolymer 10 parts, PP8 part, sorbyl alcohol 3 parts, degradation agents 1 part, antioxidant 1 part, antimonous oxide 1 part.
The preparation method of above-mentioned materials
The cleaning of waste material: the process white of plastic waste and coupling processing is put in pickling tub and soaks 2 days, then pull out, dry.
The fertilizer dried is pulverized, after melting of heating, adds saponification EVA, chlorination Butadiene/Styrene segmented copolymer, PP, sorbyl alcohol, degradation agents, antioxidant, antimonous oxide, make it become thick, 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 water-cooled travelling belt in transmitting procedure, packs to obtain the plastic grain of toughness modification to end.
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.
