Abstract
The present invention relates to the acrylic resin that a kind of suitable extrusioning blowing process prepares hollow product, it is prepared by the following method：After 60 90 parts by weight of polypropylene resin binders are well mixed with 10 40 weight account polyethylene resin binders, it is added in double screw extruder and carries out melting extrusion, produce；The acrylic resin base-material is the block copolymer of propylene and ethene, and ethylene contents are 3 8wt%, and melt flow rate (MFR) is 0.1 2.0g/10min；The polyvinyl resin base-material is high density polyethylene (HDPE), and melt flow rate (MFR) is 0.1 1.0g/10min.The hollow polypropylene product wall thickness obtained using the acrylic resin extrusion-blown modling of the present invention is uniform, the unstressed sign that turns white, while also maintains intensity, heat-resisting and chemical reagent-resistant performance that polypropylene should have, is adapted to prepare the hollow product that size is 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, wherein, middle-size and small-size hollow product is larger to the demand of polyethylene, accounts for 80%.Plain polypropylene (PP)
Melt strength it is relatively low, sag resistant poor-performing in blow-molding process, therefore seldom applied to the research in terms of hollow product, so
And polypropylene relative density is smaller than polyethylene, processing characteristics is excellent, and polyacrylic heat resistance is better than polyethylene, when poly- third
When alkene is applied to hollow product, compared to PE products, both finished product, and resulting product intensity itself can be reduced with material saving
It is more excellent with heat resistance.Therefore, research and development have certain potential market valency suitable for the PP PP Pipe Compounds of hollow product
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 prepares hollow system
The acrylic resin of product, it both can reduce cost, and gained system compared to conventional polyethylene hollow product with material saving
Product intensity itself and heat resistance are more excellent.
It is the specific technical scheme of the present invention below：
A kind of suitable extrusioning blowing process prepares the acrylic resin of hollow product, and it is prepared by the following method：Will
After 60-90 parts by weight of polypropylene resin binder is well mixed with 10-40 weight account polyethylene resin binders, it is added to twin-screw and squeezes
Go out and melting extrusion is carried out in machine, produce.
Above-mentioned acrylic resin base-material is the block copolymer of propylene and ethene, ethylene contents 3-8wt%.
Above-mentioned acrylic resin base-material melt flow rate (MFR) is 0.1-2.0g/10min, most preferably 0.3-0.7g/
10min。

Above-mentioned polyvinyl resin base-material melt flow rate (MFR) is 0.1-1.0g/10min, most preferably 0.2-0.5g/
10min。
The screw diameter of the double screw extruder is 25mm, draw ratio 40, screw speed 200-300rpm.
The extrusion temperature of the double screw extruder is 200-220 DEG C.
Beneficial effect：The hollow polypropylene product wall thickness being prepared by technical solution of the present invention is uniform, unstressed hair
White sign, while intensity, heat-resisting and chemical reagent-resistant performance that polypropylene should have also are maintained, the suitable size for preparing is
0.5-4L hollow product.
