Abstract
The invention discloses a flame-retardant reinforced polycarbonate composition. The flame-retardant reinforced PC composition comprises the following components by weight portion: 650 to 820 portions of PC-based resin, 100 to 200 portions of glass fiber, 50 to 100 portions of main flame retardant, 20 to 40 portions of toughening agent, 3 portions of dripping resistant agent, 5 to 10 portions of lubricant, and 4 to 6 portions of antioxidant. The flame-retardant reinforced polycarbonate composition not only has the characteristics of high rigidity, heat resistance and good dimensional stability, but also has good processing property and good appearance, so the polycarbonate composition can be used as an applicable material for shells of low-voltage electric appliances such as plastic-shell circuit breakers and the like.
Description
Technical field
The present invention relates to a kind of flame-retardant enhancement type polycarbonate (PC) composition, the application relates to the method that makes glass enhanced polycarbonate resin have flame retardant properties, relate to the composition that is used for this method, and pass through this class flame-retarded polycarbonate resin that this method is produced.Belong to the high polymer alloy field.
Background technology
Because the high strength of glass enhanced polycarbonate resin, it has very wide range of commercial purposes.Be widely used in the shell of various electrical equipment, be particularly useful for the injection molding of thin wall component.Yet glass fibre enhanced polycarbonate resin self has combustibility and material can also melted by heat and drip, and causes that adjacent material catches fire.Therefore, in order in a lot of the application, to use glass fibre enhanced polycarbonate safely, must in material, add effective fire retardant.Fire retardant needs not influence the performance of material significantly, and can not improve the cost of material in a large number.The multiple differing materials that is used to produce fire-retardant and/or dirp-proof polycarbonate composition has been described.In U.S. Pat 3 971756,4 025 297,4,130 530,5 218027 and 5 508 323, these examples of material have been described.Though have various open, these materials or cost an arm and a leg, or performance is not so good, still has the leeway of improving fire-retardant glass enhanced poly carbonate resin composition prescription.
Commercial these additives that are widely used in fire-retarded polycarbonate resin composition are organic salt, specifically sulfonate.The specific examples of these salt is a fluorinated alkyl sulfonate, for example potassium perfluorobutane sulfonate and benzene sulfonate.US 3 775 367 has described the application of fluorinated alkyl sulfonate in polycarbonate resin.Yet, these materials separately and glass enhanced polycarbonate resin result of use be not fine, and in fact need other additive, generally use bromated fire retardant.Because the processing temperature of glass fiber reinforced PC is higher, requires mostly to be the bromination superpolymer, thereby to cost an arm and a leg than higher heat decomposition temperature so be used for the fire retardant of PC.
Summary of the invention
The object of the invention: a kind of very good mechanical properties that has is provided, has good appearance, environmental protection flame retardant in-dash computer composition with low cost.
Above-mentioned purpose of the present invention can be achieved through the following technical solutions:
This flame-retardant reinforced PC composition, it is formed and proportioning is: PC base resin 650～820 weight parts, glass 100～200 weight parts, main flame retardant 50～100 weight parts, toughner 20～40 weight parts, anti-dripping agent 3 weight parts, lubricant 5～10 weight parts, oxidation inhibitor 4～6 weight parts.Described main flame retardant is a tribromo triple phenoxyl triazine, and described toughner is PE, and described lubricant is the mixture of OP wax and ethylene-acrylic acid copolymer.
In actual production, this flame-retardant reinforced PC composition, used PC base resin are the mixing of medium mobile PC and the high PC of flowing, and melting index is the mixture of several PC base resins of 5～24.
Described glass fibre is a roving, and diameter is 8～15mm.
Described main flame retardant is a tribromo triple phenoxyl triazine.Tribromo triple phenoxyl triazine is the patented product of Israel Dead Sea bromine company, has good heat endurance and flame retardant resistance efficiently, and it is fire-retardant to be mainly used in ABS in the past.Owing to contain bromine and nitrogen simultaneously in the molecule, so flame retarding efficiency is very high, interpolation just can reach V0 on a small quantity.
Described anti-dripping agent is the PTFE micro mist that AS coats, and PTFE content is 50～80%
Described toughner is HDPE, LLDPE, and a kind of among the LDPE, melting index is at 2～10g/10min, preferred HDPE.The PE low price is well below various elastomericss.
Described lubricant is that OP wax and ethylene-acrylic acid copolymer mix.
Described oxidation inhibitor can be selected oxidation inhibitor such as organic Hinered phenols, amine, phosphorous acid esters, can be one or both, and Hinered phenols is 1076,1098,1010 etc., and phosphorous acid esters are 168,626 etc.
Fire-retardant reinforced polycarbonate composition of the present invention can be selected twin screw extruder, and general processing temperature scope can be controlled between 240-260 ℃.
Fire-retardant reinforced polycarbonate composition according to above technical scheme proposition, owing to not only have the good characteristics of rigidity height, thermotolerance and dimensional stability and possess good processibility and flame retardant resistance, and has a good surface appearance, no glass fibre exposes, so can be used as the material of electric component products such as low-voltage apparatus housing, terminal box, connector, switch such as breaker of plastic casing.
