Technical field
The present invention relates to a kind of fire-retardant master granule, specifically a kind of PC engineering plastics highly effective flame-retardant master batch.
Background technology
Polycarbonate (PC) is a kind of thermoplastic engineering plastic of excellent combination property, there is outstanding shock resistance, resistance to creep and good stability of the dimension, higher mechanical strength can be kept in higher temperature range, nontoxic, dielectric properties are excellent, are the engineering plastics that rapid development is the fastest and the size of capacity is maximum in recent years.PC itself has certain flame retardant resistance, according to relative molecular mass and different grafting situation, oxygen index is 21% ~ 24%, flame retardant properties reaches UL94 V-2 level, be better than common plastics, although PC can put out certainly, but still be difficult to meet some Application Areas as the requirement to PC flame retardant properties such as the casing of televisor, computer, printer and assembly, transformer winding, trolley part, material of construction.In addition, during PC burning, the hot melts of drippage very easily causes neighbouring material to catch fire.For this reason, must carry out flame-retardant modified to PC.
Summary of the invention
The object of the present invention is to provide a kind ofly to add less, the PC engineering plastics highly effective flame-retardant master batch of easy to use, fire-retardant efficient, safety and the good over-all properties of maintenance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of PC engineering plastics highly effective flame-retardant master batch, and its component by mass percent proportioning is: PC resin carrier 70% ~ 90%, trichlorobenzene sodium sulfonate (STB) 1% ~ 5%, bromo PC oligopolymer 5% ~ 10%, anti-dripping agent 3% ~ 5%, hydrolysis agent 2% ~ 4%, dispersion agent 1% ~ 3%.
Described PC resin carrier is polycarbonate, and its proportion is 1.18 ~ 1.20g/cm 3, molding shrinkage is 0.5% ~ 0.8%.
Described bromo PC oligopolymer is brominated polycarbonate oligomer.
Described anti-dripping agent is polytetrafluoroethylene (PTFE) or polyvinylidene difluoride (PVDF) (PVDF).
Described hydrolysis agent is phenyl glycidyl ether or dihydroxyphenyl propane bisglycidyl ether.
Described dispersion agent is TAS-2A.
The preparation method of above-mentioned a kind of PC engineering plastics highly effective flame-retardant master batch 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 270 DEG C ~ 290 DEG C, cooling granulation, drying packing, get product.
The invention has the beneficial effects as follows, compared with prior art, the fire-retardant master granule that the present invention obtains is applied to PC engineering plastics when carrying out flame-retardant modified, it has, and flame retarding efficiency is high, addition is few, Heat stability is good, dispersed good, material over-all properties remarkable, and easy to use, cost performance is high.
