Background technique
Polypropylene (PP) is important thermoplastic polymer, be widely used in household electrical appliance, mechanical fitting, office appliance and
The fields such as Communication Equipment.PP have it is light, nontoxic, odorless, chemical stability is good, excellent electrical property (under normal circumstances, surface
Resistivity is 1016~1018Ω), and at normal temperature common solvent is not dissolved in, the advantages that water imbibition is small.
Polystyrene (PS) has excellent thermodynamic property, good toughness, chemical-resistant good, and there are also good self-lubrications
And (under normal circumstances, surface resistivity is 10 for excellent electrical property16-1018Ω) the advantages that.
In recent years, PP and PS be blended prepare composite material research it is commonplace, but have the following deficiencies:
1, since PP and PS have a good electrical insulating property, the effect easy to produce static electricity when being contacted with the external world in this way, most
It may cause dust eventually and other little particles be adsorbed in product surface, fire may occur when serious.
2, since the wearability of PP and PS are general, thus they have in the wearability of the certain pairs of products such as medical treatment, military project it is specific
It is required that technical field have certain limitation.
