A kind of polypropylene vial used for cosmetic and preparation method thereofTechnical field
The present invention relates to plastic containers preparation field, more particularly to a kind of polypropylene vial used for cosmetic and preparation method thereof.
Background technology
Because plastic bottle is lightweight, it is easily worked, and manufacturing cost is relatively low, therefore plastic bottle has been widely used as the product container in the fields such as food and drink, commodity.However, in daily life, the invasive organism such as bacterium is ubiquitous, many products are easily contaminated during storage, if people's human body in practical product is contacted with plastic bottle, just easy bacterial infection, so as to threaten health.
The Chinese patent of Application No. CN201510550180.5 discloses a kind of environmentally-friendly plastic bottle and preparation method thereof, wherein, in parts by mass, environmentally-friendly plastic bottle is made up of following component raw material：High density polyethylene (HDPE) 20-30 parts, asbestos fibre 10-20 parts, nylon 5-10 parts, PLA 10-20 parts, polylactic resin 10-20 parts, polycaprolactone 5-10 parts, makrolon 5-10 parts, polystyrene 5-10 parts, methyl-silicone oil 3-5 parts, bulking agent 1-5 parts and coupling agent 3-5 parts.Environmentally-friendly plastic bottle degradation speed is fast, and its intensity, fine heat-resisting performance, is Green Product.
The Chinese patent of Application No. CN201310169406.8 discloses a kind of double-layer polyethylene liquid, medicinal bottle and preparation method thereof, belongs to plastic drug package processing technique field.The liquid, medicinal bottle is made up of internal layer and outer layer, and internal layer is made up of high density polyethylene (HDPE), and outer layer is made up of the component of following weight percentage：68%~88% high density polyethylene (HDPE), 0.2%~3% antioxidant 264,0.05%~2% antioxidant CA and 10%~30% aluminium hydroxide.It is an advantage of the invention that with good anti-flammability, barrier properties for gases and impact strength, so as to meet the demand of liquid preparation storage, transport, while also can guarantee that the quality of liquid preparation.
Although above-mentioned plastic bottle has preferable intensity, anti-flammability, without antibacterial functions.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of polypropylene vial used for cosmetic and preparation method thereof.Polypropylene vial used for cosmetic of the invention on the basis of intensity is good, with antibacterial functions.
Concrete technical scheme of the invention is：A kind of polypropylene vial used for cosmetic, is obtained by the raw material of following weight portion：Polypropylene 80-120 parts, propane diols 10-30 parts, carboxymethylcellulose calcium 2-4 parts, antiseptic 6-8 parts, plasticizer 2-4 parts, toughener 2-4 parts, antioxidant 2-4 parts, lubricant 4-6 parts, Photoresist 2-4 parts.
Polypropylene vial of the invention has antibacterial functions, and antibacterial actual effect is long, and intensity is high, and good toughness is ageing-resistant, moreover it is possible to plays light blocking effect, is particularly suitable for the container of cosmetics.
Preferably, the antiseptic is one or more mixture in silver nitrate, silver iodide, zinc oxide, nano silicon, nano titanium oxide.Above-mentioned antiseptic inherently safe, nontoxic and comparatively good with polyacrylic compatibility, the good dispersion in polypropylene matrix, antibacterial actual effect is long.
Preferably, the plasticizer is ATBC.Plasticizer can increase polyacrylic plasticity, be easy to machine-shaping.
Preferably, the toughener is copolymer of methyl methacrylatestyrene.Toughener can improve the toughness of plastic bottle body.
Preferably, the antioxidant is phenolic antioxidant.
Preferably, the lubricant is paraffin or Tissuemat E.Lubricant can be conducive to ductility of the polypropylene in shaping, be easy to processing.
Preferably, the Photoresist is cellulose or lignin.
A kind of preparation method of polypropylene vial used for cosmetic, step is as follows：
1）, respectively weigh each raw material and add the raw material into and mixed in reactor, heat melting；
2）, by the raw material after melting pass through extruding machine extrusion moulding；
3）, the raw material of extrusion moulding is molded embryo by injection machine；
4）, by the embryo successively by bottle blowing, prolong modeling, cooling, it is interior it is cold, abandon and pressurize, be made bottled；
5）, finished product after de- bottle.
It is compared with the prior art, the beneficial effects of the invention are as follows：On the basis of intensity is good, with antibacterial functions, and antibacterial timeliness is long for polypropylene vial used for cosmetic of the invention.
