Abstract
The invention relates to a toughening polypropylene drip irrigation tape composite material and a preparation method therefor. The composite material is composed of, by weight, 60%-80% of recycled polypropylene, 2%-3% of antioxidants, 1%-2% of light stabilizers, 5%-15% compatilizers and 10%-25% of polyethylene. The preparation method for the composite material is as follows: recycled polypropylene, antioxidants, light stabilizers, compatilizers and polyethylene are prepared; the prepared materials are placed in a high-speed stirrer, and stirring is started; stirring is carried out for 10-40min, shutdown and power-off are carried out, the mixed material is taken out and dried in the air. When a product prepared from the composite material is compared with a product prepared from recycled polyethylene, the toughening effect is raised by 110%, the processability and the fluidity are raised greatly, and the cost of a polypropylene product is lowered by 300-500 yuan/ton.
Description
Technical field
The invention belongs to field of polymer composite material, relate to matrix material of a kind of tenacity-increased profax drip irrigation zone and preparation method thereof.
Background technology
Polypropylene weathering resistance is not good enough, easily stress cracking phenomenon is there is in application process, and polypropylene and polyethylene consistency bad, the main method two kinds of current raising polypropylene articles weathering resistance, one in formula, directly adds oxidation inhibitor and photostabilizer to improve its ageing resistance, another kind is in process of production, the ageing-resistant top layer of one deck is covered in polypropylene surface, thus reach aging-resistant object, even if adopt polypropylene toughness-increasing modified dose to carry out toughened polypropylene composite, its toughening effect neither clearly and cause the production cost of product to increase, such as publication number be CN102977456A patent discloses a kind of polypropylene toughness-increasing modified dose and polypropylene modification goods, the content and component proportion of polypropylene toughness-increasing modified dose: polyethylene 15-50wt.%, polypropylene 15-50wt.%, ethene and octene copolymer POE20-55wt.%, initiator 0.1-2.0wt.%, oxidation inhibitor 0.05-1.0wt.%.The above-mentioned polypropylene toughness-increasing modified dose of polypropylene modification tubing made and injecting products is adopted to be by above-mentioned polypropylene toughness-increasing modified dose of 2-15wt.% and acrylic resin 85-98wt.% physical mixed, tinting material is appropriate, Single screw extrusion pipe equipment is extruded polypropylene modification tubing, injection moulding polypropylene modification goods on injection moulding machine.The shock strength of polypropylene modification goods improves 28-34.5%, and the melt temperature of polypropylene modification goods rises 1.5-1.8 DEG C, and its degree of crystallinity adds 26.7-35.2%.Its weak point is on the basis that toughening effect is equivalent, its ethene and octene copolymer POE price very high, and the operation preparing polypropylene toughness-increasing modified dose and polypropylene modification goods is more loaded down with trivial details, certainly will increase the cost of its matrix material, also add difficulty prepared by material.
Summary of the invention
The object of the invention is to provide a kind of low cost, effective, preparation method simple, and can the matrix material and preparation method thereof of tenacity-increased profax drip irrigation zone.
The present invention is by polypropylene alkene reworked material, oxidation inhibitor, photostabilizer, compatilizer and polyethylene material composition, polypropene recycled materials is that various polypropylene articles is through repeating the reworked material recycled, it is that particle diameter is at 3-5mm, length is less than the granules regeneration material of 5mm, compatilizer is propylene-based elastomeric, propylene-based elastomeric is a kind of olefin type elastomer, for the multipolymer of semicrystalline propylene and ethene, be made up of the repeating unit of isotatic polypropylene and the ethene of random distribution, polyethylene material be without production use and particle diameter at 3-5mm, length is less than the particulate material of 3mm, its oxidation inhibitor is Hinered phenols antioxidant, photostabilizer is photomask agent and UV light absorber, and photomask agent is carbon black.Each component is by weight percentage: polypropene recycled materials 60%-80%, compatilizer 5%-15%, polyethylene material 10%-25%, oxidation inhibitor 2%-3%, photostabilizer 1%-2%, and preparation method comprises the following steps successively:
(1) by weight percentage polypropene recycled materials, oxidation inhibitor, photostabilizer, compatilizer and polyethylene material are prepared;
(2) material prepared is placed in homogenizer to start to stir;
(3) stir after 10 to 40 minutes and shut down power-off, the material mixed is taken out, then dries.
Advantage of the present invention is:
Compared with the goods that the goods that the present invention prepares composite processing and plain polypropylene reclaimed materials are processed, toughening effect improves 110%, and its processibility and mobility significantly improve, and the cost of polypropylene articles reduces by 300-500 yuan/ton.
Specific embodiment
Be below embodiments of the invention:
For the matrix material that addition is tenacity-increased profax drip irrigation zone prepared by 10% propylene-based elastomeric.
Take 600g polypropylene regeneration rewinding, 100g propylene-based elastomeric, 250g polyethylene material, 30g oxidation inhibitor and 20g photostabilizer and add homogenizer; first low rate start homogenizer; within 10 seconds, start high-speed stirring button afterwards; power-off is shut down after stirring half hour; the material mixed is taken out; then dry, namely prepare the matrix material that addition is tenacity-increased profax drip irrigation zone prepared by 10% propylene-based elastomeric.
Its effect recorded after utilizing twin screw extruder blown film is in table 1.
The quantitative measurement of the matrix material of tenacity-increased profax drip irrigation zone prepared by table 1:10% propylene-based elastomeric
Visible toughening effect is obvious.
