Abstract
The invention relates to flame retardant ABS/PVC/PETG (Acrylonitrile Butadiene Styrene/Polyvinyl Chloride/Polyethylene Terephthalate Glycol) alloy plastic and a preparation method thereof. The flame retardant ABS/PVC/PETG alloy plastic comprises the following components in parts by weight: 100 parts of ABS resin, 45-55 parts of PVC resin, 10-20 parts of PETG resin, 2-4 parts of a compatibilizer and 15-25 parts of a flame retardant, wherein the flame retardant consists of 40-60wt% of polyspiro diamide phosphate and 40-60wt% of melamine cyanurate. The alloy plastic provided by the invention is relatively excellent in flame retardance and comprehensive performance, can be easily processed into parts in various shapes by an injection molding process, and is particularly suitable for various automotive upholsteries.
Description
Technical field
The present invention relates to a kind of flame-proof ABS/PVC/PETG alloy plastic and preparation method thereof.
Background technology
ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym of Acrylonitrile Butadiene Styrene) is that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping.Most of trolley part is all with injection molding forming method processing, and the advantage of ABS resin is impact-resistance, sound-proofing, scratch-resistant, and thermotolerance is better, 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 and be only second to Polyurethane and polyacrylic the third-largest resin in automobile.ABS resin can be used for Che Nei and car outer enclosure, the widgets such as bearing circle, oil guide pipe and handle and button, and car outside comprises front radiator grill and lampshade etc.
Polyvinyl chloride resin, claims again polyvinyl chloride (PVC) RESINS, synthetic by radical polymerization by vinylchlorid.English name: PolyvinylChloride, chemical structural formula: (CH
2-CHCl) n.Polyvinyl chloride resin is one of important organic synthesis material, and its product has good physicals and chemical property, is widely used in the fields such as industry, building, agricultural, daily life, packing, electric power, public utilities.
PETG is a kind of transparent plastics, is a kind of non-crystalline type copolyesters, and the comonomer that PETG is conventional is 1,4 cyclohexane dimethanol (CHDM), and full name is polyethylene terephthalate-1,4 cyclohexane dimethanol ester.PETG sheet material has outstanding toughness and high impact strength, and its resistance to impact shock is 3～10 times of modified polyacrylate class, and has very wide work range, high physical strength and excellent flexibility, high compared with PVC transparency, good luster, easily prints and has an environment-friendly advantage.
Yet the flame retardant properties of existing ABS/PVC/PETG alloy plastic is not good.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention provides a kind of flame-proof ABS/PVC/PETG alloy plastic, has good flame retardant properties.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned flame-proof ABS/PVC/PETG alloy plastic.
Technical problem of the present invention is achieved by the following technical solution:
Flame-proof ABS/PVC/PETG alloy plastic, is comprised of following weight parts component: 100 parts of ABS resin, and polyvinyl chloride resin 45-55 part, PETG resin 10-20 part, expanding material 2-4 part, fire retardant 15-25 part,
Described fire retardant is poly-spiro-phosphate diamide and/or melamine cyanurate, and preferably, described fire retardant is comprised of the poly-spiro-phosphate diamide of 40-60wt% and 40-60wt% melamine cyanurate.Spiro-phosphate diamide will be gathered and melamine cyanurate simple agitation mixes, this fire retardant can be made.
Further,
Described expanding material is a kind of or its mixture in chlorinatedpolyethylene and styrene-maleic anhydride copolymer.
The present invention also provides the preparation method of above-mentioned flame-proof ABS/PVC/PETG alloy plastic: by proportioning, take each component, after mixing, melting mixing, extruding pelletization, obtain described flame-proof ABS/PVC/PETG alloy plastic.
Concrete, can be for take each component by proportioning, in high-speed mixer, under room temperature, control rotating speed at 300-400 rev/min, mix 5-10 minute, after taking-up, proceed in screw extrusion press, extruding pelletization at 160-180 ℃ of temperature, obtains described flame-proof ABS/PVC/PETG alloy plastic.
Obviously, for improving other performances of product, can also add adaptively other auxiliary agents, as stablizer, oxidation inhibitor and tinting material etc. in the present invention.
Concrete, in the present invention:
Chlorinatedpolyethylene, No. CAS: 63231-66-3.
Styrene-maleic anhydride copolymer (S-MA multipolymer) is to be reacted and make with a small amount of maleic anhydride monomer by styrene monomer.Heat-drawn wire all surpasses 260 °F.When injection moulding, even when temperature surpasses 550 °F, the performance of this polymkeric substance is quite stable still.
Poly-spiro-phosphate diamide, makes intermediate spiro-phosphate diacid chloride by tetramethylolmethane and phosphorus oxychloride reaction, then reacts and make with diethylenetriamine with this tetramethylolmethane phosphoryl chloride.Synthetic and performance study > > (Yu Lehua at < < phosphorus-nitrogen containing carbon expansion type flame retardant, Shi Tiejun, Zhang Fang, Deng. synthetic and the performance study [J] of phosphorus-nitrogen containing carbon expansion type flame retardant. colloid and polymkeric substance, 2013,31(3): the concrete preparation method that this raw material is provided 109～111).
Melamine cyanurate, English name melamine cyanurate, No. CAS: 37640-57-6.
The flame retardant resistance of this product is more excellent, and the over-all properties of product is more excellent.Can by Shooting Technique, be processed into easily the part of different shape, can be used for making in automobile and car outer enclosure, the widgets such as bearing circle, oil guide pipe and handle and button, car outside comprises front radiator grill and lampshade etc.
