Abstract
The present invention relates to a high flowability ABS resin preparation method, wherein raw materials comprise, by weight, 20-90 parts of a grafting copolymer, 10-80 parts of a SAN resin, 0.05-5 parts of a modifier, 0.5-2 parts of a lubricant, 0.05-0.5 part of a demolding agent, and 0.03-0.3 part of an antioxidant, and a single (double) screw extruder is adopted to carry out plastication granulation to obtain the ABS resin. With the method, under the premise of no change of the types and the use amounts of the grafting copolymer and the SAN resin, the product with excellent mechanical property and excellent processing flowability is obtained, wherein the flowability is substantially increased under the premise of no loss of impact resistance, and the melt-flow index of the finished product can be maximally improved by 20 g/10 min.
Description
Technical field:
The invention belongs to engineering plastics ABS production technical field, particularly a kind of high ABS resin and preparation method thereof that flows.
Background technology:
The very outstanding engineering plastics of a kind of comprehensive mechanical property of ABS resin.The main production of ABS resin is emulsion graft polymerization-body SAN blending method at present.Plasticate and obtain ABS resin by the graft copolymer of polybutadiene rubber, monomer styrene and vinyl cyanide and styrene-acrylonitrile copolymer (SAN resin) blending.ABS resin has two complicated phase structures, and polybutadiene rubber is disperse phase, and SAN is external phase as matrix resin.The characteristic of ABS resin depends primarily on the molecular structure in ratio and the two-phase of divinyl, vinylbenzene and vinyl cyanide.Polybutadiene rubber can provide low temperature ductility and shock resistance for ABS resin, but too much rubber phase can reduce hardness, the especially mobility of gloss of resin.Fluidity of molten is an important indicator of ABS resin, and mobility decline can cause resin to be difficult to machine-shaping.In any case be the ratio of graft copolymer and the SAN resin of polybutadiene rubber-styrene-acrylonitrile and distribute the ratio of two-phase, all cannot obtain high shock resistance and high flowing property simultaneously.So do not changing under the graft copolymer of polybutadiene rubber-styrene-acrylonitrile and the prerequisite of SAN kind and ratio, can only obtain high shock resistance and high melt flowability by the additive that adds other.
Patent KR20100078694 adds a kind of vibrin to obtain the high mobile thermoplastic resin of a kind of high gloss in the ABS resin of low acrylonitrile content, SAN resin.
Patent 200910200855.8 adds vinylbenzene and the acrylonitrile copolymer of ethylene-acrylic acid resin copolymer elastomerics, gelation in styrene base resin, obtains low gloss, high-impact, high mobile ABS material, for the manufacture of automotive upholstery.
Summary of the invention:
The object of this invention is to provide a kind of high ABS resin and preparation method thereof that flows, do not changing under the prerequisite of ABS powder and SAN resin demand ratio, add a kind of oligopolymer of the aromatic olefin that contains aliphatic hydrocarbon side chain by the link in material blending granulation, obtain high impact and the high ABS finished product that melts stream index.And can obtain the different ABS finished product of performance by the adjustment of its add-on.
The invention process method is as follows:
1) graft copolymer, SAN resin, melt viscosity properties-correcting agent, lubricant, releasing agent, oxidation inhibitor are weighed and added super mixer mixing 1-10 minute by formula, add single (two) screw extrusion press to plasticate the mixture obtaining, obtain ABS resin.
2) above-mentioned 1) mixture recipe ingredient and parts by weight are:
By
Graft copolymer, SAN resin, melt viscosity properties-correcting agent, lubricant, releasing agent and oxidation inhibitor composition; Its weight part is:
3) above-mentioned 1), graft copolymer is the one in butadiene-styrene-acrylonitrile emulsion graft copolymer, butadiene-styrene-vinyl cyanide bulk graft copolymerization thing.
4) above-mentioned 1), properties-correcting agent is a kind of oligopolymer of the aromatic olefin that contains aliphatic hydrocarbon side chain, is selected to be: a kind of mixture with more than one in the linear oligomer (n≤5) of the dipolymer of the dipolymer of vinyl toluene, the trimer of vinyl toluene, vinyl toluene and trimeric mixture, vinyl toluene.
5) above-mentioned 1), lubricant and releasing agent are fatty acid acyl amine N-N ＇-ethylenebisstearamide, silicoorganic compound class silicone oil, two or more in metal soap Magnesium Stearate, calcium stearate, Zinic stearas.Oxidation inhibitor is distearyl tetramethylolmethane bisphosphate fat.
The height that the present invention obtains flows ABS resin compared with ABS resin, is not changing under the prerequisite of graft copolymer and SAN resin kind and consumption, has obtained the more excellent product of mechanical property and processing fluidity.Do not losing under the prerequisite of impact resistance, larger raising mobility, the highest 20g/10min that improves of melt-flow index of finished product.
