Description
Technical field
The present invention relates to a kind of acrylic resin, particularly a kind of extrusioning blowing process that is suitable for prepares clear hollow product
Acrylic 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 applied to hollow
Research in terms of product is seldom.
In addition, many hollow products of in the market are more demanding to its transparency, and the blowing of the resin of polyethylene kind is planted
The hollow product transparency of quilt is unable to reach the requirement of high-quality product.
The content of the invention
It is contemplated that overcome drawbacks described above, there is provided a kind of suitable extrusioning blowing process prepares poly- the third of clear hollow product
Olefine resin, it both can reduce cost, and resulting product is strong in itself compared to conventional polyethylene hollow product with material saving
Degree and heat resistance are more excellent, and transparency is high.
The present invention provides the acrylic resin that a kind of suitable blow molding process prepares clear hollow product, it is characterised in that:
By the component of following quality parts ratio, it is added in double screw extruder and is made by melting extrusion；

The function and effect of the present invention：
The product wall thickness of acrylic resin extrusion-blown modling using the present invention is uniform, transparency is high, the unstressed sign that turns white,
Intensity, the heat-resisting and chemical reagent-resistant performance that polypropylene should have also are maintained at the same time, it is 0.5-4L's to be adapted to prepare size
Hollow product.
Specifically, found in the research of the present invention, although the melt strength of polypropylene (PP) is relatively low, blow-molding process moderate resistance
Sag poor-performing, but after the atactic polymer for the alkene that itself and carbon number are not more than 8 is mutually compounded, these can be overcome
Problem, smaller than polyethylene using polypropylene relative density well, processing performance is excellent, and polyacrylic heat resistance is than poly- second
This good characteristic of alkene, and the problem of its blowing capacity is poor is made up by way of compounding, it is applied to when by the compound scheme
During hollow product, compared to PE products, both finished product, and resulting product intensity itself and heat resistance can be reduced with material saving
Can be more excellent, simultaneously because polypropylene is easier to realize transparence with respect to polyethylene.Therefore, this research and development is suitable for transparent
The polypropylene dedicated material of hollow product has certain potential market value and prospect.
