Background technology
The PC/ABS alloy is a kind of important engineering plastic alloy, has good formability and low-temperature impact-resistant performance, higher heat-drawn wire and light stability and wide application prospect and huge marketable value.Along with the expansion of PC/ABS in the range of application in electronic product field, people require day by day to improve to the PC/ABS flame retardant properties, and the flame retardant properties of PC/ABS becomes one of study hotspot.
Adopt traditionally halogen containing flame-retardant, phosphonium flame retardant, sulfur-bearing fire retardant and nano flame retardant technology etc. to carry out modification, wherein the halogen containing flame-retardant addition is few, flame retardant effect and mechanical property are best, but can emit poisonous hydrogen halide and a large amount of smog during the burning of Halogen fire retardant material, even produce the carcinogens such as diox, produce the secondary injury of fire, and resistance to migration is poor; The phosphonium flame retardant addition is large, easily suction, and flame retardant effect is general, and cost is higher; Though sulfur-bearing fire retardant addition is few, good flame retardation effect can be accelerated the thermal destruction of PC, makes degradation; Though polymer/inorganic thing nano composite material flame retardant effect and mechanical property are all better, cost is high, and unstable product quality.So, be badly in need of a kind of environment-friendly flame retardant PC/ABS alloy material with low cost, stable, very good mechanical properties of exploitation on the market.
Summary of the invention
The present invention is that the mechanical property that exists at present traditional fire retardation PC/ABS product is not high and unstable, resistance to migration is poor, the feature of environmental protection is poor and the high in cost of production problem, has proposed a kind of high-impact, environment-friendly flame retardant PC/ABS alloy material and preparation technology thereof in order to solve.Technical scheme of the present invention is PC, 45～85 parts; ABS, 10～35 parts; Novel nitrogen-phosphorus fire retardant, 5～15 parts; Compatilizer, 0～5 part; Dispersion agent, 0.5～1.5 part; Oxidation inhibitor, 0～0.5 part; Releasing agent, 0～0.5 part; Anti-resin degradation agents, 0～0.5 part; Antidrip agent, 0～0.5 part.
Described fire retardant is novel nitrogen-phosphorus fire retardant (novel condensation polymer type aryl phosphate ester), Halogen, smokeless, nontoxic, anti-migration, high, the high efficiency flame retardance of thermostability; Described compatilizer is SMA (styrene-maleic anhydride copolymer), PMMA (polymethylmethacrylate) or MBS (Methacrylate-butadiene-styrene); Described dispersion agent is EBS (vinyl bis-stearamides), TAF (ethylene bis-fatty acid amides) or silicone oil; Described oxidation inhibitor is four [methyl-β-(3,5-di-tert-butyl-hydroxy phenyl) propionic ester] pentaerythritol ester, β-positive octadecanol ester of (3,5-di-tert-butyl-hydroxy phenyl) propionic acid or three [2,4-di-tert-butyl-phenyl] phosphorous acid ester; Described releasing agent is PETS (pentaerythritol stearate); Described anti-resin degradation agents is citric acid; Described Antidrip agent is PTFE (tetrafluoroethylene).
A kind of high-impact of the present invention, environment-friendly flame retardant PC/ABS alloy material and preparation technology thereof are as follows: (1) selects blend decentralized screw combinations, make alloy and fire retardant all reach the optimum dispersion effect, barrel temperature is: 230～250 ℃ of back segments, 220～240 ℃ in stage casing, 210～230 ℃ of leading portions, screw slenderness ratio 35～40, screw speed 350～500r/min.(2) adopt " secondary hybrid system " batch mixing, at first PC, ABS and dispersion agent are mixed by the proportioning weighing, then join in the twin screw extruder after fire retardant, compatilizer and other processing aid being mixed, carry out mixing, extrude, cooling, pelletizing, get the cylindrical pellet product.
Alloy material of the present invention is to adopt novel nitrogen-phosphorus fire retardant modification PC/ABS.The more traditional phosphonium flame retardant of novel nitrogen-phosphorus fire retardant phosphorus content is high, have the advantages such as Halogen, nontoxic, smokeless, high temperature resistant, anti-transport property be strong, and overcome the easily shortcoming of suction of phosphate compounds, and after special process is processed, dieseling as red phosphorus can not occur in production process safety, environmental protection.Quote simultaneously SMA and do compatilizer, the anhydride functional group among the SMA is close with ester group structural similitude, the polarity among the PC, and vinylbenzene segment and ABS have good consistency among the SMA, thereby has effectively improved the consistency of PC/ABS alloy.In addition, because the distinctive characteristic of maleic anhydride can be given the SMA flame retardant resistance.So environment-friendly flame retardant PC/ABS alloy material excellent combination property, the especially thermotolerance of the present invention's preparation, flame retardant resistance, toughness are given prominence to, and anti-transport property is good, relative cost is lower.
