Technical field
The present invention relates to the recovery and utilization technology field of polypropene recycled materials, be specifically related to a kind of regenerating polypropylene environment protection modification material and preparation method thereof.
Background technology
China Today has entered household electrical appliance and has discarded peak period, scraps household appliances every year by generation more than 3,000 ten thousand, and so huge waste household appliances certainly leads to a large amount of waste or used plastics.The recycling of waste or used plastics has sanitary landfill, burns heat-obtaining, and resource recycling three kinds of modes, and wherein landfill easily causes the wasting of resources and secondary pollution with burning, and this runs counter to the themes of the times of environmental protection.
Nowadays, the mode of regeneration is mainly taked in the recycling of waste or used plastics, mainly comprises Direct Regeneration, modification regeneration, gasification and oiling process.But the Mechanical Properties of Products of Direct Regeneration declines comparatively large, should not make high-grade goods; Plastics high-temperature gasification, oiling are high with the technical difficulty reclaiming the low component product such as monomer, fuel oil, equipment scale is large; And some mechanical property of the goods of modification regeneration can meet or exceed the performance of unmodified resin goods, there is very high added value.Therefore, the modification regeneration of waste or used plastics is the developing direction of resource utilization recycling.
Polypropylene (PP material) is a kind of thermoplastic resin material obtained by propylene polymerization, is an important kind in five large general synthetic resins.PP is that all synthetic resins Midst density are minimum, is only 0.90 ~ 0.91g/cm3, in five large general-purpose plastics, the excellent heat resistance of PP, PP belongs to non-polar polymer, has good electrical insulating property, and PP water-absorbent is extremely low, electrical insulating property can not be subject to the impact of humidity.
Therefore, polypropylene by injection moulding, extrude, the method such as blowing and thermoforming makes various product, be widely used in fields such as packaging, automobile, household electrical appliances, building materials, chemical industry.But current PP material after a procedure, usually directly cannot carry out second stage employ, and it is rotten to degrade after abandoning, is polluted and the wasting of resources.Therefore, be necessary to provide some technical schemes, the PP material discarded to these carries out recycling, and the integration realizing waste resource utilizes, and avoids environmental pollution.
Summary of the invention
