Abstract
The invention relates to a composite material for toughening a multi-recycle polyethylene product and a preparation method of the composite material. The composite material for toughening the multi-recycled polyethylene product comprises the following components in percentage by weight: 40-60 percent of polyethylene reclaimed materials, 5-10 percent of propylene-based elastomer and 30-55 percent of polyethylene raw material. The preparation method of the composite material comprises the following steps of: putting the polyethylene reclaimed materials, the propylene-based elastomer and the polyethylene raw material which are prepared according to percentage by weight into a high-speed stirrer, stirring the components at a high speed for half an hour, powering off the high-speed stirrer to obtain a product, then taking the product out and airing the product to obtain the composite material. Experiences prove that the toughening effect of a product manufactured by using the composite material is improved by 110 percent compared with that of a product manufactured by using common polyethylene reclaimed materials; and the processability and the mobility of the product manufactured by using the composite material are remarkably improved.
Description
Technical field
The invention belongs to the polymer composite field, relate to a kind of toughness reinforcing matrix material of repeatedly recycling polyethylene products and preparation method thereof.
Background technology
rubber is generally adopted in the processing of current polyethylene products, micron order Rigid Particles Toughened composite polyethylene material, its toughening effect clearly, but weak point is, the rigidity of rubber toughened composite polyethylene material, modulus significantly descends, and modulus increases when utilizing micron order Rigid Particles Toughened composite polyethylene material, its tensile strength again can decrease, even adopt nanoparticle to come toughened polyethylene composition, its toughening effect neither be clearly, for example publication number is the preparation method that the patent of CN 1283650A discloses a kind of nm particles reinforced and toughened polyethylene composition, be characterized in nanoparticle, solvent and surface dispersant add with ultra-sonic oscillation producer or vibration whipping appts, and under existing, a small amount of solvent utilize ball mill grinding to make dispersion agent and nanoparticle Uniform Dispersion, purpose is that nanoparticle is carried out surperficial dispersion treatment, then surface treated nanoparticle is carried out after drying and polyethylene mixing preparation masterbatch on mill or twin screw extruder, again masterbatch and polyethylene are made the enhancing toughened polyethylene composition through the twin screw extruder extruding pelletization.It is more loaded down with trivial details that its weak point is to prepare the nm particles reinforced and toughened polyethylene composition operation, certainly will increase the cost of this matrix material, and strengthened the difficulty of material preparation.
Summary of the invention
The object of the invention is to provide a kind of low cost, effective, the preparation method is simple, and matrix material and preparation method that can the enhanced polyethylene Mechanical Properties of Products.
The present invention is comprised of polyethylene reclaimed materials, propylene-based elastomeric and polyethylene raw material, the polyethylene reclaimed materials is mainly that various polyethylene products are recycled through repeatedly repeating, its particle diameter is at 3-5mm, length is less than the granules regeneration material of 5mm, propylene-based elastomeric is as main properties-correcting agent, be the semicrystalline propylene of uniqueness and the multipolymer of ethene, the polyethylene raw material is not for process production utilization and particle diameter be at 3-5mm, and length is less than the particulate material of 3mm.Each component is by weight percentage: polyethylene reclaimed materials 40%---60% wherein, and propylene-based elastomeric 5%----10%, polyethylene raw material 30%---55%, the preparation method comprises the steps:
(1) by weight percentage that polyethylene reclaimed materials, propylene-based elastomeric and polyethylene preparation of raw material is good.
(2) polyethylene reclaimed materials, propylene-based elastomeric and the polyethylene raw material for preparing being placed in homogenizer begins to stir.
(3) stirring is shut down outage after half hour, and the material that mixes is taken out, and then dries.
Advantage of the present invention is:
The present invention prepares the goods of composite processing and compares with the goods of common polythene reclaimed materials processing, and toughening effect improves 110%, and its processibility and mobility significantly improve, and the cost 300-500 of polyethylene products yuan/ton.
Specific embodiment
Be below embodiments of the invention:
It is the toughness reinforcing matrix material of repeatedly recycling polyethylene products of 6% propylene-based elastomeric preparation for addition.
Take 550g polyethylene reclaimed materials, 60g propylene-based elastomeric and 390g polyethylene raw material and add homogenizer; first low rate start homogenizer; start the high-speed stirring button after 10 seconds; shut down outage after stirring half hour; the material that mixes is taken out; then dry, namely preparing addition is the toughness reinforcing matrix material of repeatedly recycling polyethylene products of 6% propylene-based elastomeric preparation.
It utilizes the effect that records after the twin screw extruder blown film to see Table 1.
The toughness reinforcing quantitative measurement of repeatedly recycling the matrix material of polyethylene products of table 1:6% propylene-based elastomeric preparation
As seen toughening effect is obvious.
