Description

A kind of PC fire-retardant master granule
Technical field
The present invention relates to a kind of PC fire-retardant master granule.
Background technology
Polycarbonate (PC) has outstanding impact property, the transparency, dimensional stability, excellent mechanical property and electrical property, higher second-order transition temperature (140 DEG C ~ 150 DEG C), heat-drawn wire (132 DEG C ~ 138 DEG C), and wider use temperature scope (-60 DEG C ~ 120 DEG C) is widely used in the field such as electric, building, packaging, medicine equipment, opticinstrument, communications and transportation, and be rapidly to the development of the field such as Aeronautics and Astronautics, computer.(oxygen index is 21% ~ 24% to the flame retardant resistance of PC, flame retardant properties reaches UL94 V-2 level) although be better than common thermoplastic polymer (as polyethylene, polypropylene etc.), but still be difficult to meet the requirement of some Application Areas to flame retardant properties, therefore must carry out flame-retardant modified to PC.Current PC is flame-retardant modified is adopt directly to add fire retardant mostly, but each based flame retardant is owing to mostly being powder, direct interpolation existence dispersiveness is bad, production technique is not easy to control and operation, be difficult to guarantee flame retardant effect etc., use fire-retardant master granule to address these problems well, and be conducive to avoiding waste and reducing environmental pollution.
Summary of the invention
The object of the present invention is to provide a kind of good flame retardation effect, PC fire-retardant master granule easy to use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of PC fire-retardant master granule, and its component by mass percent proportioning is: PC resin 20% ~ 70%, phosphorus flame retardant 15% ~ 30%, silicon-series five-retardant 10% ~ 15%, boron flame retardant 5% ~ 10%, dispersion agent 3% ~ 5%, other additive 0 ~ 5%.
Described PC resin is polycarbonate, and its proportion is 1.18 ~ 1.20g/cm 3, molding shrinkage is 0.5% ~ 0.8%.
Described phosphorus flame retardant is dihydroxyphenyl propane-bis-(diphenyl phosphoester) (BDP).
Described silicon-series five-retardant is the one in polydimethylsiloxane, PSI, polysilsesquioxane.
Described boron flame retardant is zinc borate.
Described dispersion agent is TAS-2A dispersion agent.
Other described additive is anti-dripping agent and/or oxidation inhibitor, anti-dripping agent preferably polytetrafluoroethylene (PTFE), the preferred Hinered phenols antioxidant of oxidation inhibitor and phosphite ester kind antioxidant compound.
The preparation method of above-mentioned a kind of PC fire-retardant master granule is: take each component by weight ratio, and to add respectively in high-speed mixer and fully stir after 3 ~ 15 minutes, discharging adds in twin screw extruder, extrude through melting mixing at 210 DEG C ~ 280 DEG C, cooling granulation, drying packing, obtain a kind of PC fire-retardant master granule of the present invention.
The invention has the beneficial effects as follows, compared with prior art, a kind of PC fire-retardant master granule that the present invention obtains has good flame retardation effect, dispersed good, wide adaptability and the advantage such as easy to use, and in PC, use that can to realize halogen-free flame-proof environmental protection efficient and reach the requirement of UL94 V-0 level flame retardant properties, cost is also low, thus has significant economic results in society.
