Description
Technical field
The present invention relates to plastic bottle production field, more particularly, to the PP plastic bottles and its production technology for planting a kind of improvement.
Background technology
Polypropylene（ PP）It is a kind of thermoplastic synthetic resin of function admirable, is one of five big general synthetic resins.Poly- third
Alkene has the advantages that small, nontoxic density, easy processing, excellent in cushion effect, flex stiffiness and electrical insulating property are good, can using injection,
A variety of manufacturing process such as extrusion molding, blown film, coating, spinneret, modification are processed into various industrial and civilian plastic products, are widely used in
The fields such as electronic apparatus, automobile, building materials, medical treatment, packaging.
With conventional plastic bottle material polyethylene terephthalate（PET）Compare, PP materials have following feature：
(1) it is general to need, by special thermal finalization processing, no more than 93 DEG C of hot filling be born through the PET hot-filling bottles prepared
Temperature, does not reach the hot filling requirement of tea beverage.PP by comparison, can bear 100 DEG C of filling temperature, become hot-filling Process
Obtain easy.(2) PP density is light compared with PET, and the bottle PP for manufacturing same volume saves raw material than PET；PP equipment is thrown
Money is few, and PET is the resin of the easily moisture absorption, before processing special equipment must be used to be dried；(3) PET recovery is compared
Trouble, the resistance to aggressive washes agent is weaker, can not be subjected to high-temperature sterilization, and PP materials then can be reclaimed all.By
This is visible, and the most potential market of PP beverage bottles is in heat filling beverage.Occupy very big ratio due to being packaged in beverage cost
Weight, therefore, even if using the enterprise of PET hot-filling bottles, it is also possible to therefore turn to.
Generally prepared in PP plastics and must be added to a certain amount of antioxidant in process, to ensure material
Durability.The most frequently used antioxidant is hindered phenol anti-oxidants in PP plastics, and representative is 2,6- di-t-butyls
Paracresol and four (3,5- di-t-butyl -4- hydroxyls) benzenpropanoic acid pentaerythritol esters.Research shows that Excess free enthalpy antioxidant may
Harm is healthy.Therefore, developing the preparation technology of the PP plastics of non-toxic oxidant has important effect.
The content of the invention
For the production method of the PP plastic bottles of developing non-toxic oxidant, the invention provides a kind of PP plastics of improvement
Bottle and its production technology, described production technology comprise the following steps：
（1）After dibenzoyl peroxide tetrahydrofuran is dissolved, add a certain amount of acrylic acid lanthanum be made after mixed solution with
Added after PP GRANULES is well mixed in plasticator and carry out graft copolymerization, modified polypropylene thing is obtained after plasticating uniformly
Material；
（2）To weigh in proportion after modified polypropylene material, silica, antiseptic, antioxidant, high-speed stirred by its
It is well mixed to obtain mixture；
（3）Obtained mixture is added to blending and modifying in extruder and obtains modified PP GRANULES；
（4）Modified PP GRANULES is sent into note after modeling white silk under the conditions of 140-200 DEG C to blow in all-in-one, by barrel temperature
It is set to after 150-200 DEG C, sample point is injected for four sections, four sections of speed is respectively 75-65,35-40,30-20,20-
15, four sections pressure difference 50-80,35-45,25-20,15-20 after hybrid particles processing, after being cooled down at the beginning of injecting preform, blow
The PP plastic bottles improved are stripped after modeling sizing.
Further, step（1）Described in content of the dibenzoyl peroxide in tetrahydrofuran be 0.02-0.05%；Institute
The content of acrylic acid lanthanum in the solution is stated for 0.2-0.5%.
Further, step（1）Described in temperature when plasticating be 150-200 DEG C, the described time of plasticating is 10-15 points
Clock.
Further, step（1）Described in antiseptic be shrubby sophora extract, forsythia suspense extraction, Chinese rhubarb extract in
It is one or more；Described antioxidant is in gallic acid, anthocyanidin, green tea polyphenols extract and pawpaw polyphenol extract
One or more.
Further, described step（2）Polypropylene material, silica after neutrality, antiseptic, antioxidant each group
The percentage composition divided is respectively 80-85%, 12-8%, 2-4%, 2-4%.
Further, step（3）Described in extruder blending when temperature be 140-155 DEG C, the blending time be 2-3
Hour.
Further, step（4）Described in improvement after PP bottles can be used for tea beverage, fruit drink, milk and medicine
In product.
PP bottles after the improvement of the present invention, as prepared by above-mentioned preparation method.
The features of the present invention is：Plastic bottle preparing raw material, compared with traditional PET raw materials, the PP of preparation are used as by the use of PP
Bottle has more preferable heat resistance and corrosion resistance；The present invention is modified using acrylic acid lanthanum to polypropylene, in PP materials
Introduce the anti-impact force that rare earth high polymer adds material；The present invention uses and uses natural antibacterial, antioxidant content simultaneously, it is impossible to
The shelf-life of the food of packaging is effectively ensured, while reducing the toxicity of plastic bottle, the security of product is improved.Through the present invention
Obtained PP bottles can not only be applied to soymilk, fruit juice, the packaging of the liquid food such as tea, while also can be suitably used for the bag of liquid drug
