Abstract
The invention discloses weather resistant heat resistant flame retardant PC/ABS alloy, comprising the following components according to the parts by weight: 40-70 parts of polycarbonate (PC), 10-30 parts of styrene-acrylonitrile (SAN), 5-15 parts of methacrylate graft, 5-20 parts of solid phthalic acid-1,3-dimethylphenylphosphate oligopolymer, 1-5 parts of triphenyl phosphate(TPP), 0.2-0.8 part of silicone fluid, 0.1-0.5 part of polytetrafluoroethylene(PTFE) and 0.5-1.5 parts of other assistants. The aim of the invention is to provide a flame retardant PC/ABS alloy with good compatibility, weather resistant and heat resistant and low cost which is easy to process.
Description
Technical field
The present invention relates to a kind of Weather resistant heat resistant flame retardant PC/ABS alloy.
Background technology
The PC/ABS alloy, combine both premium propertiess, improve thermotolerance and the tensile strength of ABS on the one hand, reduce the PC melt viscosity on the other hand, improve processing characteristics, reduce goods internal stress and shock strength susceptibility, be widely used in housing, electrical equipment, lawn and horticultural machine, the auto parts (dashboard, inside fitting and wheel cover) of computer and business machine products thickness.PC and ABS itself have certain consistency, and under the no compatilizer effect, performance is relevant with the ABS resin synthetic method, and generally compatilizer improves the PC/ABS alloy because the interface compatibility problem that the ABS resin synthetic method causes by adding.Compatilizer commonly used at present has: the multipolymer (as MBS) of the grafts of ABS, polystyrene maleic anhydride graft copolymer (SMA) and acrylic or methacrylic acid esters etc.The MBS effect is best, and shock strength is the highest, but MBS is more expensive, and equally with ABS all contains the divinyl composition, so weathering resistance is relatively poor, has to a certain degree limited the application of PC/ABS; Weathering resistance SMA relative consistency improvement preferably is not very desirable.
Itself has self-extinguishing PC, but with the ABS blend after flame retardant properties reduce greatly, need to improve flame retardant properties and just can reach the electric equipment products service requirements by adding fire retardant.The fire retardant that the PC/ABS alloy is commonly used has bromine system, phosphorus system, sulfonate, organosilicon, magnesium hydroxide etc.Bromide fire retardant is to use a wider class efficient flame-retarding agent in present fire retardation PC/ABS alloy, but because the toxic substance of its generation is more and bigger to performance impact, under current environmental protection situation, being substituted by Halogen agent fire retardant is a kind of trend.Phosphorus flame retardant mainly is that phosphoric acid ester fire retardant flame retarding efficiency in PC/ABS, but because molecular weight is bigger to the heat-drawn wire influence of material when low and exists and separates out and processing problems also than higher; The high molecular phosphate flame retardant is domestic basic also at the experimental stage, and external product is generally more expensive.The Sulfonates fire retardant is most effective, add less than 1% and can satisfy the material service requirements, but because addition is few, exists and disperse uneven problem, and the general requirement processing temperature requires about 300 degree, so also less in the application.Organic silicon fibre retardant is the class fire retardant that research is hotter at present, some large-scale manufacturers value, and mainly contains silicone resin and silicone oil etc., and silicone oil needs and other fire retardant interworking competence exertion effect, and addition is subjected to the processing restriction; Silicone resin is block, the broken difficult and sticking screw rod problem of existence, the domestic report that does not have concrete application facet basically.Inorganic combustion inhibitor additions such as magnesium hydroxide are bigger, and are also bigger to performance impact, and nano level modified back promotes little to flame retardant properties.That external at present application is more is liquid phosphoric acid ester fire retardant BDP and RDP, and liquid flame retardant needs the special interpolation equipment that increases, and the solid phosphate ester flame retardant with high molecular weight price is more expensive so application is also less.
Summary of the invention
The objective of the invention is in order to overcome weak point of the prior art, provide that a kind of consistency is good, weather-proof, resistance toheat is good, easy to process and fire retardation PC/ABS alloy that cost is low.
In order to achieve the above object, the present invention adopts following scheme:
A kind of Weather resistant heat resistant flame retardant PC/ABS alloy comprises following component by weight:
Polycarbonate (PC) 40-75
Styrene-acrylonitrile (SAN) 10-30
Acrylic ester grafted thing 5-15
Solid phthalic acid-1,3-3,5-dimethylphenyl phosphoric acid ester oligopolymer 5-20
Triphenylphosphate (TPP) 1-5
Silicone oil 0.2-0.8
Polytetrafluoroethylene (PTFE) 0.1-0.5
Other auxiliary agent 0.5-1.5
Aforesaid a kind of Weather resistant heat resistant flame retardant PC/ABS alloy, wherein said other auxiliary agent are one or more the mixture in oxidation inhibitor, lubricant, photostabilizer, the processing aid.
Aforesaid a kind of Weather resistant heat resistant flame retardant PC/ABS alloy, wherein said oxidation inhibitor are one or more the mixture in antioxidant 1010, oxidation inhibitor 168, antioxidant 1076, the anti-oxidant DLTP.
Aforesaid a kind of Weather resistant heat resistant flame retardant PC/ABS alloy, wherein said lubricant are N-N '-ethylene bis stearamide (EBS).
In sum, beneficial effect of the present invention:
The present invention has used for reference ABS synthetic thinking, adopt a kind of weathering resistance to contain the grafts and the SAN combination replacement ABS resin of acrylate preferably, with high molecular solid phthalic acid-1,3-3,5-dimethylphenyl phosphoric acid ester oligopolymer, silicone oil and the fire-retardant interworking system of TPP prepare a kind of Weather resistant heat resistant halogen-free flame retardant PC/ABS by the twin screw extruder blend.The material of the present invention's preparation has following advantage:
1. esters of acrylic acid grafts one side is as the toughner of PC and SAN two components, play again on the other hand and improve two component compatibility effects, no less than compatilizers such as MBS, in processing, reduced once mixingly on the alloy property of preparation, certain advantage has been arranged on performance and cost;
2. solid phthalic acid-1,3-3,5-dimethylphenyl phosphoric acid ester oligopolymer and liquid B DP cost are more or less the same, but because the molecular weight height has bigger lifting to thermotolerance, and need not to increase equipment such as volume pump;
3.TPP to a certain degree can reducing the fire retardant cost, fire retardant can improve impact and mobile again;
4. silicone oil can improve processing characteristics, and particularly processing is dispersed.
The PC/ABS alloy that adopts the present invention's preparation is except that the performance with common halogen-free flame retardant PC/ABS, more common halogen-free flame retardant PC/ABS all has certain advantage on weather-proof, heat-resisting, processing and cost, can replace application and the popularization of common halogen-free flame retardant PC/ABS to a certain extent.
