Abstract
The invention belongs to the field of polymer materials, and specifically relates to a PP pen container special material. The material is composed of the following components in percentage by weight: 60% to 80% of PP with a high melting point, 5% to 20% of PP recycled material, 10% to 15% of flexibilizer, 2% to 3% of flow modifier, and 0.1% to 2% of color master batch. The preparation method comprises steps of mixing, extruding, and injection moulding. The preparation method reasonably utilizes PP recycled material so as to make the product performance meet the requirements of pen container manufacturing, moreover, has the characteristic of saving cost, and can be dedicatedly used to manufacture pen containers.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of PP pen container PP Pipe Compound.
Background technology
Pen container is seen everywhere in people's study and work, than he can the invention history of existing several thousand, so far people still be unable to do without him, the pen container of various materials, various patterns emerges in an endless stream, it does not still take in the stationery of pen in a kind of study and work, but also often as a kind of Presents Giving relatives and friends of elegance.Along with present material technology is to environmental protection and lightweight development, the plastics of take are made the weight that pen container not only can alleviate pen container as raw material, and due to plastics recoverable, thereby have reduced the consumption of resource.
Polypropylene (PP) is a kind of wide plastics of originating.Its degree of crystallinity is high, compound with regular structure, thereby there is good mechanical property.The absolute value of Mechanical Properties of PP is higher than polyethylene, but in plastic material, still belongs to kind on the low side, and its tensile strength only can reach 30 MPa or slightly high level.The polypropylene that isotactic index is larger has higher tensile strength, but with the raising of isotactic index, the shock strength of material declines to some extent, but no longer changes after dropping to a certain numerical value.Because above-mentioned performance PP is of many uses, especially, in automotive plastic, the consumption of PP is maximum, and rate of growth is the fastest, and it has become the main raw material of collision bumper.
Automotive plastic is as higher mobility, rigidity, toughness and the thermotolerance etc. of collision bumper needs, also to there be good dimensional stability and ageing resistance, but for making pen container, it,, to the mobility of PP, rigidity, toughness, thermotolerance, dimensional stability and the performance such as anti-aging, requires not strict.So PP plastics of the prior art are when when making pen container, its cost is higher, can not meet the requirement of pen container producer to PP material cost.
In prior art; in the producing and selling of PP goods and use procedure, produce a large amount of PP feed backs; as the PP scrap stock that produce in producing the process of automobile windsheild, the PP waste material producing after bumper is discarded, these PP feed backs bring huge pressure to environment protection.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of PP pen container PP Pipe Compound, it makes product performance reach the making requirement of pen container, and has cost-saving feature by rationally utilizing PP feed back, can be specifically designed to making pen container.
Technical scheme of the present invention is: a kind of PP pen container PP Pipe Compound, and its component by following mass percent forms:
The high molten PP 60%-80% that refers to
PP feed back 5%-20%
Toughner 10%-15%
Flow ability modifying agent 2%-3%
Masterbatch 0.1%-2%.
Optimize, described toughner adopts polyolefin elastomer.
Optimize, described flow ability modifying agent 4,4 '-dihydroxy diphenylsulphone is or/and HP.
Optimize, described Masterbatch adopts black masterbatch.
The preparation method of above-mentioned PP pen container PP Pipe Compound provided by the invention, first it comprise the steps: each component according to mass percent homogenizer stirring and evenly mixing, then proceed in twin screw extruder and melt extrude, cooling, last injection moulding makes product.
Beneficial effect of the present invention is:
1, by rationally utilizing PP feed back, and add toughner and flow ability modifying agent, make the cost of product decline 10%, and physicals all reaches requirement, therefore the product performance that the present invention makes reach the making requirement of pen container, and have cost-saving feature, can be specifically designed to making pen container.
2, by the development to PP pen container PP Pipe Compound, reduced pen container producer's manufacturing cost.
3, by reclaiming PP feed back recycling, be conducive to reduce the wasting of resources, there is the effect of protection of the environment.
Embodiment
Below in conjunction with embodiment, further illustrate the present invention.
