Abstract
The invention discloses a plastic particle with modified impact strength and tensile strength. The plastic particle with the modified impact strength and tensile strength comprises the following components: 80-120 parts of waste plastic, 20-40 parts of precipitated barium sulfate treated by coupling agent, 10-20 parts of UHMWPE (ultrahigh molecular weight polyethylene)-1330 material, 5-10 parts of PA6 (polyamide) material, 3-8 parts of UHMWPE, 1-3 parts of sorbitol, 0.5-1 part of a degrading agent, 0.5-1 part of an antioxidant and 0.5-1 part of antimonous oxide. The plastic particle with the modified impact strength and tensile strength solves the problem that in the prior art, plastic recycle utilization is insufficient; plastic fertilizer is mixed with the precipitated barium sulfate treated by the coupling agent, and under the combined action of the antimonous oxide and the degrading agent, a novel regenerated material is obtained; compared with the utilization rate of the conventional plastic purely using the waste plastic, the utilization ratio is increased by 15.6%, the notch impact strength is increased by 3.5 times compared with that of PP1330 and reaches 42.3 MPa, the tensile strength is increased by 1.5 times compared with that of the PP1330 and reaches 42.4 MPa, and the elongation ratio is increased by 2.5 times higher compared with that of the PP1330 and reaches 0.6g/ 10min.
Description
technical field
The present invention relates to plastic raw materials technical field.Particularly relate to the plastic grain of a kind of impact, tensile strength 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, a kind of impact that waste utilization rate is high, the plastic grain of tensile strength modification.
For solving the problems of the technologies described above, the invention provides the plastic grain of a kind of impact, tensile strength modification, wherein, comprising following component:
