Description

Modified materials and preparation method thereof are reclaimed in a kind of discarded drip irrigation zone
Technical field
The present invention relates to polymeric material field is and in particular to modified materials and its preparation side are reclaimed in a kind of discarded drip irrigation zone Method.
Background technology
Polyethylene, as most important general-purpose plastics, has extremely extensive purposes, consumption figure is huge at home, but also Assume the trend increasing year by year.It is additionally, since the development of polymer modification technology, various modified poly ethylenes enter Market is not so that a lot of product is single kind, but the blend of multiple material.Furthermore, in various polyethylene products also Adding has various auxiliary agents, such as antioxidant, colouring agent, filler etc., and they are also impossible to be separated, compatible between them Property is very poor, the performance of reworked material can be had a certain impact, therefore will be modified work to raw material in removal process.
The polyethylene material that drip irrigation zone is adopted is that low density polyethylene (LDPE) in appropriate proportions, high density polyethylene (HDPE) are linear, low Density polyethylene be primary raw material, wherein add right amount of processing aids, blended, extrusion, granulation, be obtained.Industrial at present Prepare the raw material that this drip irrigation zone adopted and be brand-new industrial chemicals, on the high side；And various discarded drip irrigation zone is in natural ring Degrade in border, easily to environment it is therefore desirable to waste and old drip irrigation zone is carried out with recycling, on the one hand reduce ring Border is polluted, and on the other hand reduces the production cost of drip irrigation zone.
When raw material production drip irrigation zone is again acted as using reclaimed materials, due to containing substantial amounts of impurity, polyethylene in reclaimed materials Very poor with the compatibility of other processing aids, lead to the performance of produced drip irrigation zone to be had a greatly reduced quality, especially non-oxidizability and Tensile strength is difficult to meet the market demand.
Content of the invention
For above-mentioned problem, it is an object of the present invention to provide modified materials are reclaimed in a kind of drip irrigation zone, by this The drip irrigation zone that modified materials are obtained has good antioxygenic property and mechanical property.
Further object is that providing a kind of above-mentioned drip irrigation zone to reclaim the preparation method of modified materials.
For reaching this purpose, the present invention employs the following technical solutions：
Modified materials are reclaimed, containing drip irrigation zone crushed material, high density polyethylene (HDPE) 2480, bulking agent, bullet in a kind of discarded drip irrigation zone Gonosome, Tissuemat E, glycerine, precipitated calcium carbonate.Prepare this discarded drip irrigation zone and reclaim the raw material constituent of modified materials by matter Amount number meter, contains：Drip irrigation zone crushed material 50-100 part, high density polyethylene (HDPE) 2480 10-30 part, bulking agent 0.5-2 part, bullet Gonosome 0.2-1 part, Tissuemat E 0.3-1 part, glycerine 2-3 part, precipitated calcium carbonate 4-6 part；
One or more of polyethylene that described bulking agent is grafted for maleic anhydride, haloflex, pentaerythritol ester Combination, bulking agent can promote incompatible two kinds of polymer to combine in one by means of intermolecular bonding force, so To stable blend, in removal process, contain a lot of impurity, after adding bulking agent, impurity can be eliminated to drip irrigation zone reclaimed materials Impact and other auxiliary agents between, improves the compatibility between reclaimed materials and other auxiliary agents, thus increasing the physical property of product；
Described, after maleic anhydride grafted polyethylene is compounded with pentaerythritol ester, reclaimed materials can be improved further and help Compatibility between agent.Wherein, pentaerythritol ester is equally a kind of polynary hindered phenol type antioxidant, and having good prevents light and heat The discoloration causing, can increase the ageing-resistant performance reclaiming material products.
During preparation discarded drip irrigation zone recovery modified materials are raw materials used, described elastomer is ethylene-vinyl acetate copolymer (EVA), one of polyethylene octene elastomer (POE), TPUE (TPU), elastomer has well Physical property and processing characteristics, add elastomer in removal process and can effectively improve tensile strength and the fracture of reclaimed materials Percentage elongation；
The preparation method of modified materials is reclaimed in a kind of discarded drip irrigation zone：
First discarded drip irrigation zone is recycled, removal process is disposed with cutting machine, service sink, air-dry machine, breaks Broken machine, extruder, discarded drip irrigation zone is cut into 3-5 centimetre of segment through cutting machine, and the segment drip irrigation zone after cutting is defeated Deliver to service sink to be carried out, remove the impurity such as dust therein, moss, dirt and other particulate matter, then to cleaning after Drip irrigation zone is air-dried, and after removing moisture therein, delivers to disintegrating machine and drip irrigation zone is pulverized, and obtains drip irrigation zone and pulverizes Material.
Drip irrigation zone crushed material is pressed with high density polyethylene (HDPE) 2480, bulking agent, Tissuemat E, glycerine, precipitated calcium carbonate After certain proportioning mixing, melting, plasticizing, extrusion, granulation at 190～210 DEG C DEG C of processing temperature, prepared drip irrigation zone is reclaimed modified Material.
Described extrusion is to be realized by double screw extruder, and double screw extruder extrusion temperature is 190～210 DEG C.
Described extruder increases filter screen and is filtered, and filter screen is 100 mesh filter screens.
The invention has the beneficial effects as follows：Discarded drip irrigation zone is reclaimed, is avoided waste and reduce drip irrigation zone to ring The pollution in border, another aspect recycling process can reduce production cost, and the drip irrigation zone that the present invention produces has good Tensile strength and elongation at break.
