Background technology
Polypropylene (PP) is a kind of general-purpose plastics of function admirable, its chemical stability is high, also with good heat resistance,
The features such as chemical resistance, be widely used in the various fields such as automobile, household electrical appliances.Its surface resistivity is 1013-
1015Between, antistatic effect is bad, and polishing effect is also general, it is hard to adapt to the application of the prior art.
The content of the invention
The object of the present invention is to provide a kind of PP composite materials, to solve the PP materials antistatic effect of the prior art and throwing
The problem of light effect is bad.
The present invention is achieved by the following technical solutions：
A kind of PP composite materials, it is composed of the following components by weight：
The antistatic additive is graphene.
The compatilizer is SEBS.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyls)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one kind or several in 6- (3,5- di-t-butyl -4- hydroxyphenylmethyls) benzene
The mixing of kind.
The lubricant is one or more mixing in zinc stearate, calcium stearate or potassium stearate.
The beneficial effects of the invention are as follows：
In nano Ce O2Particle surface is grafted PS, can effectively improve nano Ce O2Particle is scattered in PP matrixes, so as to carry
High compatibility between them.
The addition of graphene improves the antistatic effect of PP composite materials.
