Description

A kind of conduction, antibacterial polyamide 6/polypropylene composite material and preparation method thereof
 
Technical field
The present invention relates to modifying plastics field, relate in particular to a kind of conduction, antibacterial polyamide 6/polypropylene composite material and preparation method thereof.
 
background technology:
Polypropylene (be called for short PP) because it is cheap, excellent performance, source extensively, easily processing, be widely used in the every field such as automobile, household electrical appliances, packing, medical treatment, become modern Application one of plastics the most widely.Polypropylene has light weight, nontoxic, odorless, and chemical stability is good, and electrical property is excellent, and (generally, its surface resistivity is 10 16~ 10 18Ω), and be insoluble at normal temperatures common solvent, the advantage such as water-absorbent is little.
It is good that polyamide 6 (be called for short PA6) has thermomechanical property excellence, good toughness, chemical-resistant, and (generally, its surface resistivity is 10 to also have good wear resistance, self lubricity and excellent electrical property 13~ 10 16the advantage such as Ω); So it easily absorbs water, and processing characteristics is poor.
In recent years, polypropylene and polyamide 6 being carried out to blend, to prepare the research of alloy of common occurrence.But there is following defect:
One, because polypropylene and polyamide 6 all have good electrical insulating property, easily producing accumulation of static electricity with external world's friction or while peeling off, finally cause dust and dirt to be adsorbed in product surface like this, may presence of fire or blast when serious.For fear of this electrostatic phenomenon, must carry out it antistatic modified, to adapt to some specific Application Areas.Moreover for some specific field, may need electrically conductive polyamide material, and as: national defence industry etc.For macromolecular material, generally prevent and the method for eliminating static mainly contains: (1) adds organic molecule type static inhibitor; (2) add organic macromolecule type static inhibitor; (3) prepare alloy with conducting polymer composite blend; (4) add inorganic conductive material.Also have, while generally preparing conducting polymer composite, can in plastic base, add graphite, metal powder, steel fiber etc.
Two, because polypropylene and polyamide 6 neither have antibacterial effect, therefore in daily necessities, medical treatment etc., some has the technical field of particular requirement to have certain restriction to the antibacterial effect of goods for they.
