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 with 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 vinyl cyanide, 1,3-butadiene and three kinds of monomeric graft copolymers of vinylbenzene.Its molecular formula can be written as (C

x, but 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 the very outstanding plastics variety of a comprehensive mechanical property; Not only have favorable rigidity, hardness and processing fluidity, and have the H.T. characteristics, can injection moulding, extrude or thermoforming.
All with injection molding forming method processing, the advantage of ABS resin is impact-resistance, sound insulation property, 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; Easily application, painted can also be carried 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-stable 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 is meant 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 become the fastest general engineering plastic of rate of growth in the five large-engineering plastics at present.
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; In conjunction with 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, Ginkgo Biloba Leaf Extract 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, computingmachine and business machine housing, electrical equipment, lawn horticultural machine, auto parts test board, inside fitting and wheel cover.
Yet present PC/ABS alloy flame retardant properties is not good.
Summary of the invention
To the above-mentioned deficiency that exists 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 realize through following technical scheme:
A kind of automotive upholstery comprises following components by part by weight with fire retardation PC/ABS alloy: 50 parts of ABS resins, PC resin 40-60 part, tetrafluoroethylene 0.5-1.5 part, composite flame-retardant agent 20-50 part.
Said composite flame-retardant agent is made up of following components by part by weight: 100 parts of TDEs, tricresyl phosphate (2-chloropropyl) ester 20-30 part, melamine cyanurate 10-20 part, Marinco H 10-30 part.
TDE, tricresyl phosphate (2-chloropropyl) ester, melamine cyanurate and Marinco H 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 promptly obtain said automotive upholstery with 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 promptly obtains said automotive upholstery with fire retardation PC/ABS alloy.
Obviously, for improving other performances of product, can also add other auxiliary agents adaptively, in the present invention like photostabilizer, oxidation inhibitor, tinting material and static inhibitor etc.
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 is high, Heat stability is good, and anti-ultraviolet property is good, exudative low than other bromide fire retardants.Do not produce deleterious many bromos dibenzo dioxan DBDO and PBDF DBDF when TDE thermo-cracking or burning, meet the requirement of Europe fully, environment is not worked the mischief about the Dioxins regulations with its fire-retardant material.The industry is added the flame retardant effect that ANTIMONY TRIOXIDE SB 203 99.8 PCT improves TDE usually.
Tricresyl phosphate (2-chloropropyl) ester is claimed 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 through a large amount of experiments; Four kinds of fire retardants such as TDE, tricresyl phosphate (2-chloropropyl) ester, melamine cyanurate and Marinco H are carried out reasonable composite use; Flame retardant effect is obvious; Special flame retardant effect to the PC/ABS alloy is excellent more, draws high intensity, flexural strength, modulus in flexure and shock strength and all meets the demands, and its mechanism is still waiting the further research and inquirement of contriver.
The 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 processing automobile and uses inside gadget.
