Abstract
The present invention relates to the acrylic resin that a kind of suitable blow molding process prepares clear hollow product, it is prepared by the following method：After acrylic resin base-material is well mixed with composite assistant, it is added in double screw extruder and carries out melt pelletization, produce, the acrylic resin base-material is the random copolymer of propylene and ethene, ethylene contents are 3 5wt%, melt flow rate (MFR) is 0.1 2.0g/10min, and the composite assistant includes halogen-absorber and antioxidant.It is an advantage of the invention that the transparency for the hollow polypropylene product that extrusion-blown modling obtains, yield rate and quality are higher, it is adapted to the hollow product for preparing 0.5 4L.
Description
Technical field
It is particularly a kind of to prepare the poly- of hollow product suitable for extrusioning blowing process the present invention relates to a kind of acrylic resin
Allyl resin.
Background content
Polyethylene (PE) is the kind for realizing merchandized handling in plastics blow moulding moulding material earliest, and development is most
It hurry up, most widely used kind, at present, world's extrusion-blow molding product total yield accounted for using the yield of the PE hollow products produced as raw material
Amount about 2/3rds.The melt strength of plain polypropylene (PP) is relatively low, sag resistant poor-performing in blow-molding process, therefore is applied to
Research in terms of hollow product is seldom, however, polypropylene (PP) relative density is smaller than polyethylene, processing characteristics is excellent, Er Qieju
The heat resistance of propylene is better than polyethylene, when polypropylene is applied to hollow product, compared to PE products, both can with material saving,
Finished product is reduced, and resulting product intensity itself and heat resistance are more excellent.In addition, many hollow products pair of in the market
Its transparency requires higher, and polypropylene is easier to realize transparence with respect to polyethylene.Therefore, research and development are suitable for transparent
The polypropylene dedicated material of empty product has certain potential market value and prospect.
The content of the invention
Present invention aim to address plain polypropylene in the prior art because melt strength is low, sag resistant in blow-molding process
Can difference so as to cannot be used for the problem of blow molding process prepares hollow product, there is provided a kind of suitable extrusioning blowing process prepare it is transparent in
The acrylic resin of empty product, it both can reduce cost, Er Qiesuo compared to conventional polyethylene hollow product with material saving
Obtain product intensity itself and heat resistance is more excellent, transparency is high.
It is the specific technical scheme of the present invention below：
A kind of suitable blow molding process prepares the acrylic resin of clear hollow product, is prepared by the following method：Will be poly-
After allyl resin base-material is well mixed with composite assistant, it is added in double screw extruder and carries out melt pelletization, produce.
Above-mentioned acrylic resin base-material is the random copolymer of propylene and ethene, ethylene contents 3-5wt%.
The melt flow rate (MFR) of above-mentioned acrylic resin base-material is 0.1-2.0g/10min, most preferably 0.5-1.0g/
10min。
The composite assistant includes halogen-absorber and antioxidant.
Further, the halogen-absorber is any one in calcium stearate or hydrotalcite.Halogen-absorber adds
Measure as the 0.01-0.2wt% of acrylic resin base-material.
Further, the antioxidant is made up of antioxidant A and antioxidant B, and antioxidant A is two-[3,3- bis--(the tertiary fourths of 3-
Base -4- hydroxy phenyls)-butyric acid] in glycol ester or four [β-(3,5- di-tert-butyl-hydroxy phenyls) propionic acid] pentaerythritol esters
Any one；Antioxidant B is three (2,3- di-tert-butyl-phenyls) phosphite esters or double (2,6- di-t-butyl -4- aminomethyl phenyls)
One kind in pentaerythritol bis-phosphite.Antioxidant A dosage be acrylic resin base-material 0.01-0.2wt%, antioxidant
B dosage is the 0.01-0.3wt% of acrylic resin base-material.
Further, the screw diameter of the double screw extruder is 25mm, draw ratio 40, screw speed 100-
300r/min。
Further, the extrusion temperature of the double screw extruder is 200-220 DEG C.
Beneficial effect：Using the present invention acrylic resin extrusion-blown modling product wall thickness is uniform, transparency is high, it is unstressed
Turn white sign, while also maintains intensity, the heat-resisting and chemical reagent-resistant performance that polypropylene should have, and the suitable size for preparing is
0.5-4L hollow product.
