Description
Technical field
The present invention relates to the thermoplastic material technical field, especially relate to a kind of shock resistance polyphenylacetylene combination and preparation method thereof.
Background technology
Shock resistance polystyrene (be called for short HIPS) is to adopt vinylbenzene and isoprene-isobutylene rubber nano sized particles to carry out the method production of bulk graft copolymerization and a kind of modified polystyrene of obtaining (be called for short PS, down not together).HIPS is except that keeping fundamental property that common PS had such as favorable rigidity, processing fluidity, thermostability, dimensional stability, easily coating, the surface luster property, also having improved PS fragility shock resistance is improved.
Because HIPS has the isostatic over-all properties more than common PS, and it is used widely at case material.Be used to make shells such as televisor, watch-dog, duplicating machine, printer, suction cleaner, telephone set, facsimile recorder, sound-track engraving apparatus, shredder, safe shaving apparatus, instrument, medical apparatus, toy as HIPS.
But because HIPS has very strong electric insulating quality, surface resistivity reaches 10
16~ 10
19Ω can make that in application electrostatic energy runs up to very high degree, thereby can adsorb dust and greasy dirt on the surface, makes finished product lose end-use performance; Static voltage can may cause disaster because of producing static release up to thousands of volts even tens thousand of volt when serious under relative movement states such as friction, collision, transmission.Therefore, possesses antistatic property when HIPS requirement when electron trade is made IC chip tray, IC support, IC encapsulation, LCD pallet, PCB pallet, SMT pallet etc.; Under make needing explosion-proof place such as combustion gas can, oil plant basin, coal mine, during the electric product housing of breaking and Dusting, transport oiler oceangoing ship etc., also require to possess antistatic property.
In order to make HIPS have antistatic property, the general employing added the lower molecular weight static inhibitor, makes its surface resistivity reduce to 10
8~ 10
12Ω, the harm of avoiding static discharge to cause.This low-molecular-weight static inhibitor is bigger to the degree of dependence of environment, it mainly is to conduct electricity as ionic ionization place by hydrophilic absorption, and the big young pathbreaker of humidity resists electrostatic efficiency and exerts an influence, continues short, rub resistance, influential to the matrix resin mechanical property not of usefulness time.
Existing shock resistance poly styrene composite material also can reach anlistatig purpose as globular graphitized carbon black or flaky electrically conductive graphite blend by adding some simple substance.Graphitized carbon black is the super-normal structure black that a kind of oil-absorption(number) is big, specific surface area is big, size distribution is big, extrude the back with the shock resistance polystyrene blend and form the spatial network passage easily, help forming the chain type conductive structure, the migration of suitable unbound electron is when the graphitized carbon black of capacity reaches critical volume, will reduce HIPS resistivity.The laminated structure of electrically conductive graphite has bigger radius-thickness ratio and overlaps the formation conductive network easily mutually, each carbon atom and other carbon atoms only form 3 covalent linkage in its structure, each carbon atom still keeps 1 unbound electron and comes transmission charge and tool electroconductibility, after mixing, meet to conduct electricity to exceed and ooze, reach antistatic requirement thereby reduce resistivity with the shock resistance polystyrene is molten.This stable lasting by the antistatic property that adds the shock resistance poly styrene composite material that graphitized carbon black or electrically conductive graphite make, but graphitized carbon black or electrically conductive graphite color are black, the finished product that makes only limits to black or dark-grey black, and the mechanical property of this in addition shock resistance poly styrene composite material is also bad.
