Description
Technical field
The present invention relates to field of plastic coloring, relate to a kind of painted ABS Masterbatch of ABS plastic shell and preparation method thereof that is used for specifically.
Background technology
ABS resin is vinyl cyanide, divinyl and cinnamic terpolymer, and its production method has blending method, copolymerization method and emulsion graft polymerization method three major types at present.By regulating three kinds of monomeric proportionings, but processability difference, the different resin of the trade mark, as ultrahigh impact type, high impact-resistant type, universal and special type etc.ABS is nontoxic, tasteless, has tough, hard, firm characteristic concurrently, and forming process is convenient, and high comprehensive performance is used very extensive in fields such as household electrical appliance, light industry stationery sports goods, automotive industry and chemical industry.
The colorize method of ABS have toner painted, dyeing draw the grain the painted and painted three kinds of methods of Masterbatch.When directly adopting toner painted, painted very simple, be easy to generate color dot, aberration is wayward, environmental pollution is bigger shortcoming but exist.It is to adopt mixing facilities such as twin screw extruder to carry out melt blending ABS and toner mixing back that dyeing draws grain painted, thereby makes painted ABS micelle.With adopt that toner is painted to be compared, draw a coloring effect to be greatly improved, but ABS need experience thermal history twice, has not only improved production cost, and damage the mechanical property of goods to a certain extent.When adopting Masterbatch painted, pigment also is dispersed in the vector resin through pre-treatment, has improved dispersing of pigments performance and coloration efficiency greatly, has advantages such as simple to operate, with low cost, environmentally safe.
It is carrier that the ABS Masterbatch generally adopts ABS, and there is some difference with forming the ABS color and luster that causes the various trades mark for the molecular structure of ABS terpolymer, and this is painted totally unfavorable for goods.Be that the Masterbatch of carrier carries out when painted with ABS, because the carrier flow performance is relatively poor, and adding proportion less (being generally 4phr), occur problems such as flow liner, color and luster inequality, aberration be wayward easily.Particularly for white domestic appliances such as air-conditioning, refrigerator and washing machine etc., the content that requires titanium dioxide in the Masterbatch when some white especially parts are painted is up to 40～60%, and the shock strength of product is had certain influence, causes some to have the parts of screw hole to split easily.Therefore, how solving the ABS Masterbatch and be easy to generate problems such as the big and shock resistance variation of flow liner, color and luster inequality, aberration when painted, is that ABS needs the urgent problem that solves when painted.
Summary of the invention
The objective of the invention is to solve the problem that above-mentioned existing ABS Masterbatch exists when painted, provide a kind of and powerful disperse, impact-resistant ABS color concentrates, it can overcome problems such as being easy to generate the big and shock resistance variation of flow liner, color and luster inequality, aberration when being applied to ABS goods painted.
Another object of the present invention provides the preparation method of above-mentioned ABS Masterbatch.
Powerful dispersion of the present invention, impact-resistant ABS color concentrates are made up of following component and weight percentage: carrier 20～50%, toner 0.01～70%, dispersion agent 0～40%, polymer bulking agents 0.5～20%, impact modifying agent 1～20%, thermo-stabilizer 0.1～2%, processing aid 0～10%, filler 0～40%.
Above-mentioned carrier is one or more the mixture in high-impact polystyrene (HIPS), polystyrene (PS), styrene-butadiene copolymer (K glue), the acrylonitritrile-styrene resin (AS).These polymkeric substance have the good mobility energy as carrier, extrude processing easily, and have consistency preferably with ABS.
Above-mentioned toner is mineral dye, pigment dyestuff or dyestuff; Described mineral dye is titanium dioxide (titanium dioxide), carbon black or zinc sulfide white etc.; Described pigment dyestuff is azo pigment, heterocycle pigment or miscellany pigment etc.
Above-mentioned dispersion agent is one or more the mixture in polyethylene wax, oxidized polyethlene wax, (ethene-vinyl acetate) copolymer waxes, the polyamide wax (EBS, modification EBS etc.).The preferential fusion and be coated on the granules of pigments surface in the course of processing of these low-molecular-weight components, thus play the effect that promotes dispersing of pigments and make it stabilization.
Above-mentioned polymer bulking agents is that styrene-maleic anhydride copolymer (SMA), high-impact polystyrene grafted maleic anhydride (HIPS-g-MAH), K glued joint one or more the mixture in the branch maleic anhydride.The polymer bulking agents that the present invention adopts contains maleic anhydride, has the certain reaction activity with mineral dye or filler such as titanium dioxide, zinc sulfide white, lime carbonate, talcum powder etc., be coated on the surface of mineral dye and filler, effectively the consistency of inorganics and vector resin in the raising Masterbatch improves painted homogeneity and stability.
Above-mentioned impact modifying agent is one or more the mixture in SBS (styrene-butadiene-styrene multipolymer), SEBS (styrene-ethylene butylene-styrene multipolymer), the SIS elastomericss such as (styrene-isoprene-styrene copolymer-s), these elastomericss and ABS have good consistency, good dispersion also can effectively absorb striking energy in matrix, makes the impact property of ABS keep good.
Above-mentioned thermo-stabilizer is one or more the mixture in phenolic antioxidant or the phosphorous acid ester.Phenolic antioxidant is as BHT, 1076,1010; Phosphorous acid ester is as 168.The adding of thermo-stabilizer can avoid in the Masterbatch course of processing vector resin to degrade, and reaches the effect that keeps the Masterbatch colour stable.
Above-mentioned processing aid is one or more the mixture in stearic acid, stearate, white mineral oil or the silicone.The adding of processing aid can reduce the frictional force of material and machine barrel, die surface, has solved problems such as surface gloss is not good, demoulding difficulty.
Above-mentioned filler is one or more the mixture in lime carbonate, talcum powder or the wollastonite.
The preparation method of powerful dispersion of the present invention, impact-resistant ABS color concentrates is: each component is prepared burden in proportion, in high-speed mixer, mixed then 5～20 minutes, adopt twin screw extruder to carry out melt blending, temperature is controlled at 180～200 ℃, screw speed is 80～400r/min, be uniformly dispersed in vector resin by the shearing of screw rod or rotor, the mixing pigment that makes, carry out granulation then, drying makes Masterbatch of the present invention.
The present invention also can adopt the Banbury mixer banburying earlier with the material that mixes in the high-speed mixer, adopts the operational path of screw extrusion press granulation to prepare Masterbatch of the present invention then.
Beneficial effect of the present invention: when ABS Masterbatch provided by the invention is applied to ABS goods painted, it has the powerful advantage of disperseing, improving impact resistance, has overcome painted flow liner, color and luster inequality, the aberration of being easy to generate of existing ABS Masterbatch than problems such as big and shock resistance variation.Simultaneously, the preparation method of ABS Masterbatch of the present invention is simple and practical, has a extensive future.
