Description
Technical field
It is more specifically a kind of to be given birth to using mixed plastic the present invention relates to Recycle of Waste Plastics field
The manufacturing process of production regeneration polypropylene fiber.
Background technology
Plastics are a kind of polymer of artificial Polymer Synthesizing, are more new industrial materials, and PP plastics（Poly- third
Alkene）It is the another fine resin kind developed after nylon, it is a kind of high density, unprotected side chain, highly crystalline linear polymerization
Object has excellent comprehensive performance.Plastics are lived to people and production brings convenient and interests, while are also generated substantial amounts of
Pollution, there is data to suggest that, the general-purpose plastics of about 70%-80% translated into waste plastics in 10 years in plastics total amount, wherein 50% will
Waste plastics was converted into 2 years, if these waste plastics are arbitrarily abandoned or irrelevantly handled, can be brought to human environment greatly
Pollution and harm, it is known as " white pollution " by people, and therefore, recycling and recycling to plastics seem particularly important.
At present, the production of polypropylene fibre is roughly divided into two kinds, and one kind is as raw material, by polymerisation to its raw material by propylene
Be modified, melt, spinning, fiber is finally made using filtering, quenching, winding in spinning melt, the technique productions
Polypropylene fiber silk low strength；Another kind is to use polypropylene resin as raw material, spinning moulding, then spindle type draw twisting mill into
Row two-stage is drawn and twisting, and the polypropylene filament of high intensity is made.Most of manufacturing enterprise of this field is spun in production regeneration PP
During silk, production model mainly uses each waste material carrying out plasticizing granulation, then plasticized granule material is further melted spinning
Silk, it is cumbersome which does not only exist technological process complexity, and regeneration polypropylene fibre obtained does not possess high stringiness, is unfavorable for
Its application production.On the other hand, traditional PP class technics of reclaim of plastic waste manufacturing enterprise, they are in the production and processing of reclaiming
In, all it is that PP classes waste plastic is directly subjected to mixing plasticizing, melting, then cooling and dicing, forms PP plastic pellets, then this is moulded
Material grain re-starts melting, spinning, and polypropylene fibre is made and spins, traditional handicraft not only cannot carry out classification use to various waste PPs
Production, it is impossible to the various waste plastic products of classified use well, and the matter of regeneration PP products cannot be further improved
Amount.
