Abstract
The invention relates to an acid/alkali-resistant polyethylene zip lock bag which is prepared from 68-85 parts by weight of polyethylene, 0.02-0.5 part by weight of plasticizer, 2-5 parts by weight of polystyrene, 5-12 parts by weight of polytetrafluoroethylene, 1-3 parts by weight of antioxidant, 0.5-2 parts by weight of antistatic agent and 0.01-1 part by weight of dispersant. The acid/alkali-resistant polyethylene zip lock bag provided by the invention has excellent resistance to acid and alkali corrosion, remains the properties of polystyrene, and also has excellent high-temperature resistance, low-temperature resistance and high lubrication property of polytetrafluoroethylene; as a result, the zip lock bag can be used in acid/alkali conditions and the conditions of high and low temperatures; and the service life of the zip lock bag is prolonged.
Description
?
Technical field
the present invention relates to plastics bag technical field, specifically a kind of acid and alkali-resistance polyethylene sealing bag.
Background technology
Sealing bag is called again valve bag, by appointing bag, sealing bag, bone bag, English: Ziplock bags, Reclosable Bag, Zipper Closure Bag, Resealable Bag), with polyethylene (LDPE) and high pressure linear polyethylene (LLDPE), pass through blowfilm shaping, hot-cutting machine bag, a kind of plastics bag that can repeat sealing of making.Sealing bag can be used for the exterior and interior packing of various small articles.With the sealing bag of the raw material production of food grade, can deposit various pot foods, tealeaves, sea-food etc., protection against the tide, waterproof, insect protected, prevent that thing is scattered; Sealing bag also can be used for the packing of clothes and other articles for daily use, of many uses.Sealing bag adds antistatic master batch can produce anti-electrostatic valve bag when blown film is produced, and is generally applied to electron trade.
The sealing bag of prior art passes through blowfilm shaping, hot-cutting machine bag by polyethylene and high pressure linear polyethylene.The sealing bag acid-alkali-corrosive-resisting performance of prior art does not reach requirement, makes its purposes greatly limited.
Summary of the invention
The object of the present invention is to provide a kind of acid and alkali-resistance polyethylene sealing bag.
Object of the present invention can be achieved through the following technical solutions:
A kind of acid and alkali-resistance polyethylene sealing bag, it is characterized in that, described sealing bag is prepared by the component of following weight part: polyethylene 68-85 weight part, softening agent 0.02-0.5 weight part, polystyrene 2-5 weight part, tetrafluoroethylene 5-12 weight part, antioxidant 1-3 weight part, static inhibitor 0.5-2 weight part, dispersion agent 0.01-1 weight part.
Described sealing bag is prepared by the component of following weight part: polyethylene 75 weight parts, softening agent 0.4 weight part, polystyrene 3.5 weight parts, tetrafluoroethylene 9 weight parts, antioxidant 2 weight parts, static inhibitor 1 weight part, dispersion agent 0.5 weight part.
Described softening agent is phthalic ester, and described antioxidant is antioxidant 1010, and described static inhibitor is alkyl sodium sulfonate, and described dispersion agent is Zinic stearas.
Polystyrene comprises ordinary polystyrene, polystyrene foamed (EPS), high-impact polystyrene (HIPS) and syndiotactic polystyrene (SPS).Ordinary polystyrene resin is nontoxic, odorless, and colourless transparent grain, like glassy hard brittle material, its goods have high transparency, and transmittance can reach more than 90%, and electrical insulation capability is good, easy coloring, processing fluidity is good, and good rigidly and chemical resistance are good etc.The being property of weak point of ordinary polystyrene is crisp, and shock strength is low, is prone to stress cracking, poor heat resistance and not resistance to boiling water etc.
Ordinary polystyrene resin belongs to amorphous macromolecule polymkeric substance, the side group of polystyrene macromolecular chain is phenyl ring, large volume side group is the physicochemical property that the random arrangement of phenyl ring has determined polystyrene, as high in transparency. and rigidity is large. and second-order transition temperature is high, and property is crisp etc.Expandable Polystyrene (EPS) is made for flood lower boiling pneumatogen in ordinary polystyrene, is subject to heat foamable in the course of processing, is exclusively used in making foam article.High-impact polystyrene is the multipolymer of vinylbenzene and divinyl, and divinyl is disperse phase, improved the shock strength of material, but product is opaque.Syndiotactic polystyrene is isostructure, adopts metallocene catalyst to produce, the polystyrene new variety of development, and performance is good, belongs to engineering plastics.
Tetrafluoroethylene is the macromolecular compound through being polymerized by tetrafluoroethylene, its skeleton symbol is-[CF2-CF2-] n-, there is good chemical stability, erosion resistance, it is one of corrosion resistance nature best materials in the world today, except molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, other all pharmaceutical chemicalss of ability boil also and do not change in chloroazotic acid, are widely used in the occasion of the antiacid alkali of various needs and organic solvent.
High temperature resistant, use working temperature to reach 250 ℃; Low temperature resistant, there is good mechanical tenacity, drop temperature to-196 ℃, also can keep 5% elongation; Corrosion-resistant, to most of pharmaceutical chemicalss and solvent, show inertia, energy strong alkali-acid resistance, water and various organic solvent; Weather, has aging life-span best in plastics; High lubricated, be frictional coefficient the lowest in solid material; Not adhering to, is surface tension minimum in solid material, does not adhere to any material; Toxicological harmless, has physiology inertia, as artificial blood vessel and internal organs, implants and has no adverse reaction for a long time.
Beneficial effect of the present invention: acid and alkali-resistance polyethylene sealing bag of the present invention has excellent acid-alkali-corrosive-resisting performance, kept poly performance, excellent high temperature resistant, low temperature resistant, the high lubricating property with tetrafluoroethylene simultaneously, meet under the soda acid, high/low temperature condition of sealing bag and use, extend work-ing life.
