Abstract
The invention relates to a method using abandoned woven bags to produce PP recycled materials and the mould-press PP pipelines. The key points of the technology are: use cutting up, cleaning, drying, melting and graining techniques to prepare PP recycling materials and add proper reinforcer, modifier, antioxidant and fresh polyolefin raw materials by the recycling materials, and use hydraulic injection to create the PP pipelines with 200mm-1500mm inner diameter. The PP pipelines of the invention can be used as the grounded draining pipe.
Description
Affiliated technical field
The present invention relates to recycling, and utilize the reclaimed materials of waste woven bag to make moulded polypropylene (PP) tubing, belong to the chemical industry environmental protection field waste woven bag.
Background technology
Woven bag is widely used in the packing that chemical fertilizer, cement, grain, salt, industrial chemicals etc. are combined product greatly, and range of application is extremely extensive, and its main component is a polypropylene.According to incompletely statistics, as the major product polypropylene of synthetic resin, have 50% output to be used to produce woven bag approximately, annual polyacrylic consumption reaches more than 1,000,000 tons.Woven bag is used widely will inevitably cause widely and is polluted the same all be called " white pollution " with agricultural mulching.Therefore, pollution how to eliminate polypropylene (PP) the woven bag significant problem that also becomes people and paid close attention to.With the waste plastics recovery utilization, be a kind of suitable way the most to eliminating white pollution, because woven bag only is used for the packing of shot-like particle and powder, be easy to separate with packed article, be convenient to recycle.But discarded woven bag diminishes because of oxidation can make molecular weight, and its flexility, mechanical strength, particularly impact strength all can reduce greatly, therefore, when recycling, must carry out modification to reclaimed materials, to improve the practicality that reclaims plastics.
At present, the domestic recycling that relates to waste woven bag also has a spot of patent and bibliographical information.Patent CN1090236A as people such as Wang Lin, the kingdom in ShenYang, Liaoning Province city be clear application, introduced " evaluation and exploration technology of flyash and polypropylene waste material ", this method goes out a kind of novel material with flyash, polypropylene waste material (as waste polypropylene woven bags), rubber powder, two zinc esters and machine oil through mixing roll is mixing, and utilizes the various plastic products on this feedstock production industry and the mariculture industry.This patent provides a kind of new thinking for the recycling of polypropylene waste material, but implements veritably to make it reach the actual performance index of some plastic products, also needs to do number of research projects, particularly needs reclaimed materials is carried out modification, enhancing etc.Chongqing turns round and look at ground plastics Electrical Appliances Co., Ltd and pays (Sichuan chemical industry and corrosion controls such as will is quick, Zhao Jingsong, 2002,1 (5), p13～15) studied PP woven bag recovery technology, and introduced and utilized styrene-butadiene block copolymerization an ancient unit of weight (SBS), styrene-isoprene-phenylethene graft copolymer (S1S), ethylene-acrylic acid or acrylate copolymer (EAA), ethylene-vinyl acetate copolymer (EVA) and several polyene flexibilizer of ethylene-octene copolymer (POE) modified effect waste and old polypropylene (PP) woven bag reclaimed materials.The result shows that the toughening effect of SIS is best, and is also higher than the breach impact strength of fresh random copolymerization PP1330, and other several toughening materials all have certain effect, and when consumption increased, its impact strength increased sharply.The document has proved the feasibility that waste and old polypropylene (PP) woven bag is recycled theoretically.(HEILONGJIANG ANIMAL SCIENCE AND VETERINARY MEDICINE such as the beam Ying Lin of institute of zootechnics and veterinary science, Guizhou Province, 1998,7, p18～19) studied the feasibility of utilizing waste woven bag to make separation layer production carpet-type lawn, observe by the lawn production effect, the turf grass growing time that woven bag and nonwoven are made separation layer does not have significant difference, presentation of results: waste woven bag is better than nonwoven as separation layer.The document provides a kind of a kind of method of recycling of polypropylene waste woven bag.
Various reports in sum all have certain practicality, but can't really be applied to reality.
Summary of the invention
The technical problem that the present invention mainly solves is: a kind of method of utilizing waste woven bag to produce the polypropylene reclaimed materials and utilize this reclaimed materials manufacturing moulded polypropylene (PP) tubing is provided, and this moulded polypropylene (PP) tubing can be used as buried with drainpipe (gravity flow).
Technical scheme of the present invention realizes by following steps:
(1) chopping is cleaned: remove the cotton thread of waste woven bag sealing, and chopping, washing is dried;
(2) melt extrude: the woven bag that will shred after cleaning is sent the film comminutor to, after the fusion, under extrusion pressure promotes, extrudes from some apertures of comminutor die head, and the process trough shaped is polypropylene (PP) reclaimed materials into strips;
(3) granulation: strip polypropylene (PP) reclaimed materials is cut into the long granular reclaimed materials of 2mm～6mm with pelleter.
(4) preparation of moulded polypropylene (PP) tubing: the prescription of making moulded polypropylene (PP) tubing is made up of following several compositions: polypropylene (PP) reclaimed materials, reinforcing agent, modifier, antioxidant and fresh polyolefin raw material.Design different raw material proportionings, the addition of polypropylene (PP) reclaimed materials between 0%～100%, reinforcing agent composition addition between 0%～35%, the modifier addition between 0%～30%, antioxidant composition addition between 0%～2% and fresh polyolefin raw material addition between 0%～50%, make polypropylene (PP) tubing of internal diameter between 200mm～1500mm by the fluid pressure type plastic-injection moulding machine.
