The ternary alloy material comprises polycarbonate, ABS, polypropylene and a compatilizer. The polycarbonate/ABS/polypropylene ternary alloy material disclosed by the invention has high mechanical strength and heat distortion temperature; the preparation process is simple, the technology is controllable, and the cost is low; and the polycarbonate/ABS/polypropylene ternary alloy material can be widely applied to machine parts, electronic components, electric equipment enclosures, connectors and the like.
Description
Technical field
The present invention relates to the high molecule alloy material field, be specifically related to a kind of PC/Abs/polypropylene ternary-alloy material and preparation method thereof.
Background technology
Polycarbonate (Polycarbonate is called for short PC).It is a kind of water white indefiniteness thermoplastic material, have excellent in cushion effect, creep resistance, good stability of the dimension, heat-resisting, nontoxic, the advantage such as dielectric properties are good, of many uses in fields such as electronic apparatus, automobile, medicine equipment, machinery, building and lighting apparatuss, become important a member in the five large-engineering plastics.Yet pure PC resin also exists poor, the easy stress cracking of processing fluidity,, the shortcoming such as easily aging and wear resistance relatively poor responsive to breach, limits it in the application in some field.
Acrylonitrile-butadiene-phenylethylene multipolymer (ABS resin).It has good over-all properties, admirably dimensional stability, electrical property, wear resistance, dyeability are arranged, and forming process and mechanical workout are better, are widely used in the fields such as auto parts machinery, electronic apparatus accessory, but the heat-drawn wire of ABS is lower, and thermotolerance is bad.
It is little that polypropylene (Polypropylene is called for short PP) has density, good electrical property with high-frequency insulation, be not subjected to that humidity effect, raw material sources are abundant, cheap, the relative characteristics such as simple of synthesis technique.But because its poor toughness, shrinkage strain is large, and creep resistance is poor, and the defective such as easily become fragile during low temperature is subject to certain restrictions using.These shortcomings make itself and engineering plastics still have a certain distance at aspect of performance.At present mainly come PP is carried out the high performance modification by physical blending or the physical blending that has chemical modification concurrently.
At present, existing Makrolon/polypropylene alloy material take the grafts of PP as compatilizer, improves the compatilizer of PC and PP, improves the erosion-resisting characteristics of polycarbonate/polypropylene material.But the rigidity of this material and toughness effect are unsatisfactory, meet high temperature and are out of shape easily, and demixing phenomenon occurs easily in the injection moulding process, are difficult to satisfy it in the application of machinery and field of electronics.
Application number is that 201010276248.2 the described material of Chinese invention patent is a kind of PC/ASA binary alloy, it is the modified version of PC/ABS alloy that this binary alloy belongs to, the ASA of its introducing is a kind of weathering resistance multipolymer more outstanding than ABS, its objective is a kind of good weatherability of preparation, can be used for outdoor material.
Summary of the invention
The object of the invention is to according to above shortcomings in the prior art, introduce ABS, and select corresponding grafts to do compatilizer, satisfy industrial application to the requirement of rigidity and toughness to prepare polycarbonate/acrylonitrile-butadiene-phenylethene copolymer/polypropylene ternary-alloy material.
Another purpose of the present invention is to provide the preparation method of above-mentioned alloy material.
Above-mentioned purpose of the present invention is achieved by the following technical programs:

As a kind of preferred version, described compatilizer is the grafts of grafts, the styrene-ethylene-butadiene-styrene block copolymer of polyacrylic maleic anhydride grafts, acrylonitrile-butadiene-styrene (ABS), in methyl methacrylate-styrene-butadiene rubber(SBR) multipolymer one or several.
As a kind of preferred version, described polycarbonate, ABS resin, polyacrylic mass ratio are 16:2:1 ~ 4:3:2.
As a kind of preferred version, additive described in PC/Abs of the present invention/polypropylene ternary-alloy material is one or several in oxidation inhibitor, photostabilizer, the lubricant.Oxidation inhibitor accounts for 0.2 ~ 0.3% of material total mass; Lubricant accounts for 0.3 ~ 0.5% of material total mass; Photostabilizer accounts for 0.1 ~ 0.3% of material total mass.
Polycarbonate in PC/Abs of the present invention/polypropylene ternary-alloy material was controlled moisture in 3 hours below 0.1% 105 ℃ of lower bakings.
The preparation method of PC/Abs of the present invention/polypropylene ternary-alloy material is as follows:
1. prepare burden: example takes by weighing raw material in mass ratio, and described raw material comprises polycarbonate, acrylonitrile-butadiene-styrene copolymer, polypropylene, compatilizer;
2. mix: load weighted raw material is put in the high speed mixer, mixed, obtain compound;
3. melt extrude: compound is put into extruded in the melt extruder and granulation.
Be that 201010276248.2 Chinese invention patent is compared with application number, the purpose that this patent is introduced ABS is in order to improve the consistency of PC/PP binary alloy, different from above-mentioned patent purpose, the ternary alloy main application fields of preparing is automotive upholstery, or indoor device.
Compared with prior art, the present invention has following beneficial effect:
(1) injection moulding provided by the present invention novel tertiary high molecule alloy material, remedied the shortcoming that current material can not satisfy rigidity and toughness reguirements simultaneously, have simultaneously preferably toughness and rigidity, and heat-drawn wire is higher, cost is relatively cheap, preparation process is simple, and technique is controlled easily;
(2) injection moulding provided by the invention novel tertiary high molecule alloy material can be widely used in the aspects such as mechanical fitting, power tool, electronic apparatus accessory, junctor;
(3) the injection moulding provided by the invention preparation method of novel tertiary high molecule alloy material, the mode of employing segmentation melting can guarantee that material can not be subjected to pyrolytic decomposition, can guarantee that also various material mixing are even simultaneously, consistency is good.
