A kind of toughness reinforcing enhancing paintable regeneration ABS and preparation method thereof
Technical field
The present invention relates to a kind of toughness reinforcing enhancing paintable regeneration ABS and preparation method thereof.
Background technology
ABS resin is vinyl cyanide, divinyl and styrol copolymer (abbreviation or the abbreviation of Acrylonitrile-Butadiene-Styrene).ABS resin is a kind of intensity height, good toughness, is easy to the thermoplastic macromolecule material of machine-shaping, is widely used in automotive industry, mechanical industry and electrical instrumentation industry, like gear, blade, panel board, casing, splash pan, handrail, safety helmet etc.Because ultraviolet degradation takes place the divinyl in the ABS resin easily, therefore many ABS resin product surfaces all can apply paint (generally being that acrylic acid series or polyurethane series coat with lacquer), and it is ornamental but also can alleviate the goods photoaging not only to have satisfied goods.Along with the increasingly stringent of the shortage and the environment protection of petroleum resources, the application of regeneration ABS resin progressively increases.Because market competition is fierce unusually, a lot of ABS production of articles commercial cities begin to adopt regeneration ABS to expect to reduce cost.Yet reclaim ABS resin because of solarization; Its mechanical property especially erosion-resisting characteristics can not show a candle to the ABS virgin material, reclaims the plastics that more or less all contain other in the ABS resin such as PC, PP, PE etc. simultaneously, the incompatible and layering of non-polar resin wherein such as PP, PE and ABS; Migration surface and enrichment easily; Thereby reduce the polarity that reclaims the ABS resin surface, cause reclaiming ABS resin and be difficult to japanning, the polarity paint that promptly applies comes off easily.Above drawbacks limit the application of regeneration ABS material.Chinese patent CN1646280, CN101016401 have proposed to improve the method that reclaims the ABS mechanical property, but do not mention the method that reclaims the difficult japanning in ABS surface that how to solve.The present invention proposes a kind of toughness reinforcing enhancing paintable regeneration ABS and preparation method thereof, not only promotes the mechanical property that reclaims ABS, and solves the problem that reclaims the difficult japanning of ABS.
Summary of the invention
The purpose of this invention is to provide a kind of toughness reinforcing enhancing paintable regeneration ABS and preparation method thereof.
The technical scheme that the present invention taked is:
A kind of toughness reinforcing enhancing paintable regeneration ABS, it is made up of following raw material: the compatilizer of the recovery ABS of 60-90 mass parts, the toughner of 5-20 mass parts, 1-6 mass parts, the filler of 1-15 mass parts, the oxidation inhibitor of 0.1-1 mass parts.
Preferably, the consumption that reclaims ABS is the 80-90 mass parts, and the consumption of toughner is the 8-15 mass parts, and the consumption of compatilizer is the 2-4 mass parts, and the consumption of filler is the 5-10 mass parts, and the consumption of oxidation inhibitor is the 0.2-0.5 mass parts; Reclaiming ABS is ABS goods reclaimed materials or tankage or mouth of a river material.
Said toughner is at least a among ABS high glue powder, EVA, SEBS, SBS, the EPDM.
Described compatilizer is the maleic anhydride graft polyolefine.
Described maleic anhydride graft polyolefine is a kind of among PP-g-MAH, the PE-g-MAH.
In the described maleic anhydride graft polyolefine, the percentage of grafting of maleic anhydride >=5%.
Described filler comprises lime carbonate, talcum powder, wollastonite, permanent white, kaolin.
Described oxidation inhibitor is at least a in Hinered phenols antioxidant, the phosphite ester kind antioxidant.
The preparation method of a kind of toughness reinforcing enhancing paintable regeneration ABS may further comprise the steps: various mixing of materials are even, and under 190-220 ℃, melt extrude again and get final product.
The invention has the beneficial effects as follows: regeneration ABS pellet provided by the invention has excellent mechanical property and varnishability.
