Description
The present invention relates to Flameproof thermoplastic resin compositions, relate in particular to the Flameproof thermoplastic resin compositions that is used for molding, comprise a kind of by the halogen polycarbonate with contain base resin, a kind of phosphate-ester composition, a kind of perfluoro alkane polymkeric substance and a kind of zeolite that phenylethene grafted copolymer is formed.Thermoplastic resin composition of the present invention also can be contained additive, accounts for a part on demand, as mineral filler, thermo-stabilizer, dyestuff and/or pigment.
Polycarbonate molding compositions is widely used in the parts of automobile and electrical equipment.It possesses over-all propertieies such as the good transparency, high impact and thermotolerance.But the polycarbonate molding compositions molding processability can be not good, add a little other resins and use together.The moulding compound that for example comprises polycarbonate resin and styrene resin just has excellent machinability and high notched impact strength.
The polycarbonate molding compositions that is used for household electrical appliance and computer case material should be a heat resistant fire-proof.For this purpose, just adopted halogen-containing and/or antimony containing compounds makes thermoplastic composition have flame retardant resistance.For example, U.S.P 4,983, and 658 and 4,883,835 have disclosed a kind of halogen contained compound of employing as fire retardant.But halogen-containing compound owing to there is hydrogen halide to discharge, cause the mould corrosion, and the toxic gas that discharges also is fatal deleterious to the people when fire event in moulding process.
U.S.P 4,692,488 disclose a kind of thermoplastic composition, comprise phosphorus compound, tetrafluoro ethylene polymer and ABS (acrylonitrile-butadiene-styrene terpolymer) graftomer of the vinylbenzene of halogen aromatic polycarbonate, halogen and vinyl cyanide thermoplastic copolymer, halogen.Polymkeric substance with a kind of phosphorus compound and perfluoro alkane makes polycarbonate/ABS resin composition possess flame retardant properties, the particle that catches fire when preventing to burn drippage.Although this resin combination has had satisfied flame retardant resistance, because the migration of fire retardant has produced unsafty check surface in the moulding process, i.e. so-called " stream juice ", thus reduced the physical properties of this resin combination.For anti-fluid stopping juice phenomenon, in polycarbonate/ABS resin composition, can add low polyphosphate, as U.S.P 5,204, disclosed in 394.U.S.P 5,204, and 394 disclose a kind of polymeric blends, comprise aromatic polycarbonate, contain styrol copolymer and/or contain phenylethene grafted copolymer and the blend of low polyphosphate or low polyphosphate as fire retardant.
In above-mentioned U.S patent, the example of representational phosphorus compound is triaryl phosphate and low polyphosphate.When containing monomer triaryl phosphate resin combination surface and apply with strong shearing force, its surface has the trend that lamina forms.This will cause occurring stream juice phenomenon when molding, make the resin combination thermotolerance descend.And stream juice phenomenon can not take place when using oligomeric triaryl phosphate, because when the low polyphosphate that toward resin in, adds with the same amount of monomer triaryl phosphate, and the too late monomer triaryl phosphate of the flame retardant properties of low polyphosphate.In addition, be exposed to high temperature as after 80 ℃ or following for some time of above temperature in phosphoric acid ester, phosphoric acid ester has the trend of decomposing and being reduced to phosphoric acid.This phenomenon can cause that the flame-retarded resin mechanical property descends.And with the monomer phosphoric acid ester by contrast, low polyphosphate since phosphoric acid ester to decompose the mechanical property downward trend cause even more serious.
