The alloy comprises the following components in part by weight: 560 to 640 parts of PC resin, 100 to 220 parts of ABS resin, 80 to 140 parts of flame retardant, 50 to 100 parts of filler, 3 parts of anti-dripping agent, 30 to 50 parts of toughening agent, 3 parts of lubricating agent and 4 to 9 parts of antioxidant. According to the technical scheme, because of good glossiness and rigidity and good mechanical property and flame-retardant property, the flame-retardant PC/ABS composition can be used as a special material for the notebook computer shell.
Description
Technical field
The present invention relates to the PC/ABS alloy, be specially the special-purpose halogen-free flame retardant PC/ABS alloy of a kind of notebook computer shell, belong to the high polymer alloy field.
Background technology
Polycarbonate/acrylonitrile-butadiene-phenylethene copolymer plastic alloy material (hereinafter to be referred as the PC/ABS alloy) is a kind of high-performance thermoplastic engineering plastics with good over-all properties that develop rapidly is got up over nearly 40 years; It has had the good characteristic and the one of polycarbonate (PC) and two kinds of materials of acrylonitrile-butadiene-styrene copolymer (ABS) concurrently; Like shock resistance, thermotolerance and the rigidity etc. of excellence beyond the characteristics; Therefore the processing fluidity and the dimensional stability that also have high gloss, excellence are widely used in fields such as communication electronic machine, office equipment, household electrical appliance and trolley part.
Yet, because PC/ABS alloy itself but is a kind of inflammable material, in the plurality of applications occasion; Particularly IT, field of electronics; Component for the plastic material that uses is processed like flameproof case, switch, connector etc., all require material to have flame retardant resistance; For example flame retardant resistance must reach the UL-94V0 level, to improve its safety in utilization.
The development of Green Chemistry and technology has brought new production theory, and the eco-friendly low cigarette of development of new, low toxicity, Halogen product have become the research emphasis of green fire retardant material.In recent years, phosphonium flame retardant, silicon-series five-retardant, oxyhydroxide fire retardant, etc. the without halide fire retardant in PC ABS alloy, obtained development fast.Wherein phosphorous flame-retardant not only can be effectively fire-retardant to alloy, and can improve the processing fluidity of alloy; In China, halogen-free flame retardant PC/ABS alloy material is one of current industrialization of new high-technology major products of first developing of country.
Notebook computer is one of computer Development Trend, and in the U.S., notebook computer has accounted for 70% of PC market, still has very big development space now.The most frequently used material of notebook computer shell is exactly fire retardation PC/ABS alloy, and notebook computer shell is at present just towards ultra-thin, high rigidity, and Gao Guang, the direction of halogen-free flameproof develops, and this has just proposed requirements at the higher level to material.
Traditional fire retardation PC/ABS alloy rigidity is poor, and it is known in alloy, adding filler.US5849827 and WO99/07788 have reported that adding inorganic powder in halogen-free flame retardant PC/ABS alloy can improve flame retardant resistance, does not relate to the raising rigidity; CN00817689 mentions and in halogen-free flame retardant PC/ABS, adds stress crack resistant and the rigidity that talcum powder improves material, does not mention the glossiness that improves material.
Summary of the invention
The object of the invention: aim to provide the special-purpose PC/ABS alloy of a kind of notebook computer shell, the halogen-free flame retardant PC of the high rigidity high gloss of its tool/ABS compsn is exclusively used in notebook computer shell.
The object of the invention can be realized through following technical scheme:
The PC/ABS alloy that a kind of notebook computer shell is special-purpose, it is formed and proportioning is: PC resin 560-640 weight part, ABS resin 100-220 weight part, fire retardant 80-140 weight part, weighting agent 50-100 weight part, anti-dripping agent 3 weight parts, toughner 30-50 weight part, lubricant 3 weight parts, oxidation inhibitor 4-9 weight part.
In the actual production, this PC compsn, used PC base resin are the high PC of flowing, and promptly melting index (MFR) is the PC base resin more than 20.Like the PC-122 of Qi Mei company, the 201-22 of DOW company etc.
Used ABS resin is that MFR is at the mobile ABS of the height more than 20.Like 746 of Qi Mei company, 8391 etc. of high bridge petrochemical industry.
Used fire retardant is RDP (a Resorcinol biphosphonate), one or more among BDP (dihydroxyphenyl propane biphosphonate) and the RDXP (gathering the Resorcinol biphosphonate).
Used weighting agent is one or more in talcum powder, mica and the wollastonite.The preferably talc powder.Talcous particle diameter is at the 0.5-3 micron.
Used toughner is ABS high glue powder or acrylic ester elastomer.
Used anti-dripping agent is the tetrafluoroethylene that AS (propylene fine-styrol copolymer) coats.The tetrafluoroethylene mass percent is 50-80%.
Used lubricant is PETS (tetramethylolmethane four stearates).
Used Hinered phenols antioxidant is 245 or 1010.
Used phosphite ester kind antioxidant is 168.
Fire-retardant anti-ultraviolet PC of the present invention/ABS compsn can be selected twin screw extruder, and general processing temperature scope can be controlled between 230-240 ℃.
The fire retardation PC that technical scheme prepares according to the present invention/ABS compsn, owing to not only have good glossiness and rigidity, and possess favorable mechanical performance and flame retardant resistance, can be used as the notebook computer casing PP Pipe Compound.
