Abstract
The invention relates to an organic polymer composite material, and particularly relates to cold-resistant polyethylene plastic. The cold-resistant polyethylene plastic is prepared from the following raw materials in parts by weight: 40-50% of high-density polyethylene, 15-30% of linear low density polyethylene, 5-10% of styrene-butadiene block copolymer (SBS), 5-10% of polyolefin elastomer (POE), 5-10% of ethylene-vinyl acetate copolymer (EVA) and 5-10% of acrylonitrile butadiene styrene (ABS). The plastic fabricated by polyethylene does not crack in a low-temperature state at -40 DEG C, and has strong cold resistance, elongation at break, large impact strength of a cantilever beam gap, and low cost of raw materials by adding a few of materials with a certain ratio, and industrial production is carried out.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of novel cold-resistant vinyon.
Background technology
High density polyethylene(HDPE) is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity, owing to having larger molecular weight, therefore has higher rigidity, good mechanical property.But the toughness of high density polyethylene(HDPE) is lower, be very easy to fracture.Linear low density polyethylene has higher softening temperature and melt temperature, and good toughness, heat-resisting, winter hardiness good.But linear low density polyethylene often rigidity is bad, the poor-performings such as environmental stress crack resistance, impact strength, tear-resistant intensity.Therefore, its joint development is made it there is at low temperatures good performance and there is positive effect.
Summary of the invention
The present invention is directed to the crackly problem of polythene material under current low temperature environment, provide a kind of and can tolerate the novel cold-resistant vinyon that utmost point low temperature still keeps excellent toughness.
The invention provides following technical scheme: novel cold-resistant polythene material of the present invention, is made up of high density polyethylene(HDPE): 40-50% by weight following composition; Linear low density polyethylene: 15-30%; SBS:5-10%; POE:5-10%; EVA5-10%; ABS:5-10%.
The Production Flow Chart of novel winter hardiness plastics of the present invention is: the mixture that contains high density polyethylene(HDPE), linear low density polyethylene, SBS, POE, EVA, ABS is heated to be not less than at the temperature of melting point polyester, and make its reaction synthetic resins with 60g/10 minute or lower melt flow rate, then inject in bolt special, injection moulding machine with independent temperature control nozzle, and the temperature setting in injection moulding machine is set to 220 degrees Celsius, after injection moulding, can obtain novel cold-resistant vinyon.
The advantage of the novel cold-resistant plastic of the present invention: by several a certain proportion of Material Additions, make the plastics made by polyethylene can be under the low-temperature conditions of subzero 40 degree, can not rupture and there is stronger winter hardiness, elongation at break and socle girder notched Izod impact strength are large, and material cost is low, be conducive to implement industrial production.
Embodiment
Be below the most preferred embodiment of novel cold-resistant vinyon of the present invention, therefore do not limit protection scope of the present invention.
Embodiment mono-, provides a kind of novel cold-resistant vinyon, is made up of by weight high density polyethylene(HDPE): 40-50% following composition; Linear low density polyethylene: 15-30%; SBS:5-10%; POE:5-10%; EVA5-10%; ABS:5-10%.
The mixture that contains high density polyethylene(HDPE), linear low density polyethylene, SBS, POE, EVA, ABS is heated to be not less than at the temperature of melting point polyester, and make its reaction synthetic resins with 60g/10 minute or lower melt flow rate, then inject in bolt special, injection moulding machine with independent temperature control nozzle, and the temperature setting in injection moulding machine is set to 220 degrees Celsius, may novel cold-resistant vinyon after injection moulding.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
