Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, relate in particular to a kind of automotive upholstery fire retardation PC/ABS Alloy And Preparation Method.
Background technology
ABS resin (acrylonitrile-styrene-butadienecopolymer, ABS are the acronyms of Acrylonitrile Butadiene Styrene) is a kind of intensity height, good toughness, be easy to thermoplastics type's macromolecular material structure of machine-shaping.
ABS resin is the graft copolymer of vinyl cyanide, 1,3-butadiene and three kinds of monomers of vinylbenzene.Its molecular formula can be written as (C
8H
8C
4H
6C
3H
3N)
xBut contain the graft copolymer of divinyl and the mixture of acrylonitritrile-styrene resin in fact often, wherein, vinyl cyanide accounts for 15-35%, divinyl accounts for 5-30%, styrene comprise 40-60%, and the modal ratio of emulsion method ABS is A: B: S=22: 17: 61, and the ratio of B is often lower among the substance law ABS, is about 13%.
ABS is the general thermoplastic engineering plastic that grows up 1940's, it is a plastics variety that comprehensive mechanical property is very outstanding, not only have favorable rigidity, hardness and processing fluidity, and have the high tenacity characteristics, can injection moulding, extrude or thermoforming.
All with injection molding forming method processing, the advantage of ABS resin is impact-resistance, sound insulation, scratch-resistant to most of trolley part, and thermotolerance is better, and is more attractive in appearance than PP, is specially adapted to the comparatively strict parts of horizontal impact-resistance and use temperature.ABS resin is to use in the automobile to be only second to Polyurethane and polyacrylic the third-largest resin.ABS resin can be used for Che Nei and car outer enclosure, widgets such as bearing circle, oil guide pipe and handle and button, radiator grill and lampshade etc. before the car outside comprises.
ABS resin is processed easily, finish size stability and surface luster are good, application, painted easily, can also carry out metallize, plating, welding and suitability for secondary processing such as bonding, can be widely used in field of electronics, comprise various offices and consumer electronics/electrical equipment, office electrical equipment comprises electronic data processing machine, office equipment.In electronic apparatus market, ABS resin will keep its status in requiring fire-retardant and high heat-resisting electronics/electrical equipment market in recent years, fire-retardant and high heat-proof ABS resin with the competition of engineering plastic alloys such as ABS/PC in have remarkable advantages.
PC refers to polycarbonate, is the high molecular polymer that contains carbonate group in the molecular chain, can be divided into broad varietys such as aliphatics, aromatic series, aliphatic-aromatic according to the structure of ester group.Wherein the mechanical property owing to aliphatics and aliphatic-aromatic polycarbonate is lower, thereby has limited its application aspect engineering plastics.Only have at present that aromatic copolycarbonate obtains suitability for industrialized production.Because the singularity on the polycarbonate structure has now become the fastest general engineering plastic of rate of growth in the five large-engineering plastics.
The PC/ABS alloy, it is the mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer, be by polycarbonate and thermoplastic plastic rubber that acrylonitrile-styrene-butadienecopolymer ABS alloy forms, combine the excellent specific property of two kinds of materials, the formability of ABS material and the mechanicalness of PC, shock strength and character such as heatproof, uvioresistant UV can be widely used on automotive interior parts, business machine, the communication apparatus, electrical home appliances and the set lights.The typically used scope is phone housing, computer and business machine housing, electrical equipment, lawn horticultural machine, auto parts dashboard, inside fitting and wheel cover.
Yet present PC/ABS alloy flame retardant properties is not good.
Summary of the invention
At above shortcomings in the prior art, one of technical problem to be solved by this invention provides a kind of automotive upholstery with fire retardation PC/ABS alloy, has good flame retardancy.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned automotive upholstery with fire retardation PC/ABS alloy.
The present invention seeks to be achieved through the following technical solutions:
A kind of automotive upholstery comprises following components by part by weight: 50 parts of ABS resin, PC resin 40-60 part, tetrafluoroethylene 0.5-1.5 part, composite flame-retardant agent 20-50 part with fire retardation PC/ABS alloy.
Described composite flame-retardant agent is made up of following components by part by weight: 100 parts of TDE, tricresyl phosphate (2-chloropropyl) ester 20-30 part, melamine cyanurate 10-20 part, magnesium hydroxide 10-30 part.
TDE, tricresyl phosphate (2-chloropropyl) ester, melamine cyanurate and magnesium hydroxide are mixed, can make this fire retardant.
The present invention also provides the preparation method of above-mentioned automotive upholstery with fire retardation PC/ABS alloy: take by weighing each component by proportioning, after mixing, melting mixing, extruding pelletization namely obtain described automotive upholstery fire retardation PC/ABS alloy.
Concrete, can be for take by weighing each component by proportioning, in high-speed mixer, the control rotating speed mixed 5-10 minute at 300-400 rev/min under the room temperature, changed in the screw extrusion press after the taking-up, extruding pelletization under 240-260 ℃ of temperature namely obtains described automotive upholstery fire retardation PC/ABS alloy.
Obviously, for improving other performances of product, can also add other auxiliary agents adaptively, as photostabilizer, oxidation inhibitor, tinting material and static inhibitor etc. in the present invention.
Concrete, in the present invention:
TDE, English name: 1,2-Bis (pentabromophenyl) ethane, English another name: 1,1 '-(Ethane-1,2-diyl) bis (pentabromobenzene), CAS number: 84852-53-9, molecular formula: C
14H
4Br
10, its bromine content height, Heat stability is good, anti-ultraviolet property is good, exudative low than other bromide fire retardants.Do not produce poisonous many bromos dibenzo dioxan DBDO and PBDF DBDF when TDE thermo-cracking or burning, meet Europe fully about the requirement of Dioxins regulations with its fire-retardant material, environment is not worked the mischief.The industry is added the flame retardant effect that ANTIMONY TRIOXIDE SB 203 99.8 PCT improves TDE usually.
Tricresyl phosphate (2-chloropropyl) ester claims fire retardant TCPP again, English name: Tris (2-clorisopropyl) Phosphate, CAS No:13674-84-5.
Melamine cyanurate, English name melamine cyanurate, another name: melamine pyrophosphate; Halogen-free flame retardants MPP; Melamine cyanurate; MCA; The halogen-free flameproof lubricant, CAS number: 37640-57-6.
The contriver draws by a large amount of experiments, four kinds of fire retardants such as TDE, tricresyl phosphate (2-chloropropyl) ester, melamine cyanurate and magnesium hydroxide are carried out reasonable composite use, flame retardant effect is obvious, special more excellent at the flame retardant effect of PC/ABS alloy, draw high intensity, flexural strength, modulus in flexure and shock strength and all meet the demands, its mechanism is still waiting the further research and inquirement of contriver.
Thermotolerance and the flame retardant resistance of this product are more excellent, and preparation technology is simple, and product cost is low, and The comprehensive performance is more excellent.
Automotive upholstery of the present invention can be processed into the part of different shape with Shooting Technique easily with fire retardation PC/ABS alloy, can be used for making the automobile inside gadget.
