Polypropylene is because having preferable processing characteristics and excellent mechanics, physics, chemical property, while light weight is inexpensive, extensively
It is general to be applied to the industries such as automobile interior exterior decorations, household electrical appliance and electronics, it is the most fast universal thermoplastic of current growth rate.
However, because polypropylene surface hardness is low, the household appliances shell or inner and outer decorative parts of automobile scraping and wiping resistance performance being made from it are poor,
Product surface is easily scratched, so as to influence presentation quality.Meanwhile, polypropylene is higher due to specific insulation, and surface easily collects
Poly- electric charge and cannot conduct, cause product surface to carry electrostatic and cause the phenomenons such as dust suction and spark discharge.Therefore, how to improve
The scratch resistance and antistatic behaviour of polypropylene material turn into the key issue of this kind of material of exploitation.
At present, for polypropylene material scraping and wiping resistance performance difference and the not enough problem of antistatic effect, there are reports and
Solution, is concentrated mainly on to scratch-resistant auxiliary agent and antistatic additive is added in polypropylene material, such as amide-type and silicone
The antistatic additive of scratch-resistant auxiliary agent and ionic and nonionic surface active agent class.Chinese patent 200810023328.X is public
A kind of scraping-resistant automobile inner fitting special-purpose material and preparation method thereof is opened, using amide-type and silicone scratch-resistant additive compound
To improve the scraping and wiping resistance performance of PP composite material.United States Patent (USP) US4000102 discloses a kind of antistatic polypropylene and is combined
Material and preparation method thereof, polypropylene material is improved using anion surfactant fatty acid zinc as antistatic additive
Antistatic property.The scratch-resistant auxiliary agent and antistatic additive of these additions are mostly micromolecular compound, are easily moved in injection moulding process
Product surface is moved to, causes product in use the problems such as tacky and precipitation is also easy to produce in the presence of light and heat, influence
Using effect.Although short-acting impermanent, it is impossible to reach additionally, ionic surfactant class antistatic additive antistatic effect is good
To the requirement of permanent anti-static；And nonionic surface active agent class antistatic additive antistatic effect is poor, addition is more, cost compared with
It is high.
The content of the invention
The purpose of the present invention is exactly to provide a kind of with preferably resistance to for the defect for overcoming above-mentioned prior art to exist
Scratch performance and permanent antistatic performance, while tacky PP composite material and preparation method thereof can be resisted again.
A kind of scratch-resistant, anti-tacky and permanent anti-static PP composite material, are matched somebody with somebody by the raw material of following percentage by weight
It is made：
In the PP composite material system that the present invention is applicable, described polypropylene is in 230 DEG C, 2.16kg loading condictions
