The toughness reinforcing AS matrix material of above-mentioned high gloss is by K resin and AS resin-bonded, AS resin is carried out to modification, realized the alloying of AS and K resin, improved intensity, the toughness of mixture, and glossiness, can when mixing mutually with arbitrary proportion with ABS, keep better the background color of mixture.
The preparation method of the toughness reinforcing AS matrix material of above-mentioned high gloss only need melt extrude mixed being incorporated at suitable temperature of each component can obtain product by formula, its preparation method technique is simple, and condition is easily controlled, with low cost, feature low for equipment requirements, is suitable for suitability for industrialized production.
Embodiment
In order to make the technical problem to be solved in the present invention, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the present invention provides a kind of high gloss toughness reinforcing AS matrix material, comprises the component of following weight percent:
Particularly, above-mentioned AS resin is fine-cinnamic multipolymer of propylene, is by vinyl cyanide and the styrene copolymerized macromolecular compound forming, and generally containing vinylbenzene 15%-50%, is transparent and the yellow solid to amber pin look of band, the present blend composition mainly as ABS.Preferably shock strength is 30 ± 5J/M, and density is 1.04-1.07g/cm
3aS resin, LG chemistry 80HF for example, platform NF2200.
Above-mentioned K resin is styrene-butadiene transparent anti-impact resin, claim again K-Resin(K-resin), that to take vinylbenzene, divinyl be monomer, take lithium alkylide as initiator, adopt the synthetic a kind of segmented copolymer of anionic solution polymerization technology, it is transparent, bright, also has high toughness and shock resistance simultaneously.In a preferred embodiment, described K resin is the styrene-butadiene copolymer that transmittance is greater than 88%, and shock strength is (or being about) 40 ± 5J/M, and density is 1.01-1.03g/cm
3, for example strange beautiful PB-5903 or PB-5910.
Above-mentioned K resin and AS resin are combined through hybrid junctions, make matrix material have good color effects, reach well transparent, gloss intensity, can be used as the selection of high-end electronic product material.
Above-mentioned compatilizer can combine each component of matrix material and bring into play synergy.Conventional compatilizer is ABS grafted maleic anhydride compatilizer.In a preferred embodiment, the AS resin that described compatilizer is 98-99:0.2-0.3:1.6-1.7:0.2-0.3 by weight ratio, white oil, maleic anhydride and tasteless DCP form, can be described as AS grafted maleic anhydride, it can be by extruding each component mixed melting to make, wherein, extrusion temperature is 140-170 ℃.Specifically can pass through twin-screw extrusion fusion-grafting, screw speed is made as to 270-300 rev/min.In above-mentioned compatilizer system by using, the above-mentioned AS resin base material of the optional use of AS resin, white oil is selected technical grade, and the rank that maleic anhydride and tasteless DCP all can select purity to be greater than 98%, can reduce mixing of other impurity like this, guarantees the purity of color.Its key index is DCP content, can control the color of compatilizer after adjustment, for follow-up use is laid the groundwork.Preferably, the weight ratio of AS resin, white oil, maleic anhydride and tasteless DCP is 98:0.2:1.6:0.2-0.3.
Traditional method is prepared AS class mixture, all uses ABS grafted maleic anhydride, and matrix is ABS, but when ABS mixes with AS arbitrary proportion, has a strong impact on the background color transparency of mixture.The present invention is by the above-mentioned AS grafted maleic anhydride of self-control, and adjust by the consumption to initiator DCP, make compatilizer color reach ideal effect, and the background color that can keep better mixture, adopt AS grafted maleic anhydride can make main body A S be combined with glass interface tightr, composite strength reaches best effect simultaneously.
Above-mentioned lubricant is conducive to melt extruding of matrix material, can improve the physicals of extruded product, makes product surface smooth good-looking.The preferred fusing point of described lubricant is the amide waxe class modifier of 141.5 ℃-144.5 ℃, and concrete example is as Guangzhou Ou Ying chemical industry TAF, EBS.
Above-mentioned oxidation inhibitor can delay or suppress the carrying out of polymkeric substance oxidising process, thereby stops the aging of polymkeric substance and extend its work-ing life.Preferably, described oxidation inhibitor is Hinered phenols antioxidant, and fusing point 115-150 ℃, as vapour bar IRGANOX1098, IRGANOX1010.
The preferred above-mentioned self-control maleic anhydride graft AS of the present invention plays synergistic effect as compatilizer, because the main body of whole invention is AS material, toughened system is K resin, maleic anhydride graft AS can with two reach completely compatible, it is ultimate attainment that thereby the effect that makes AS compatilizer performs to, the shock strength of matrix material is obviously improved, and higher than two material of main parts, obtain the toughness reinforcing AS matrix material of high gloss of excellent performance.
Correspondingly, the embodiment of the present invention also provides the preparation method of the toughness reinforcing AS matrix material of a kind of high gloss, comprises the following steps:
S01, according to the toughness reinforcing AS composite-material formula of above-mentioned high gloss, take respectively each component;
Described in S02, general, take each component and carry out mixing treatment, obtain mixture;
S03, described mixture is melt extruded, granulation, obtains the toughness reinforcing AS matrix material of described high gloss.
Particularly, each component preferred content in the formula of the toughness reinforcing AS matrix material of high gloss in above-mentioned steps S01 and formula and kind as described above, in order to save length, do not repeat them here.
In above-mentioned steps S02, each component is carried out the time of mixing treatment and can be adjusted flexibly according to actual production conditions, as long as each component premix fully, if the equipment of mixing can be mixing machine etc.In a preferred embodiment, mixing treatment be by each component (as rotating speed is greater than 300r/min) combination treatment at a high speed 10～15 minutes, each component is mixed.
In above-mentioned steps S03, mixture melt extrude the technique that can adopt this area routine.For each component is better acted synergistically in melt extruding, give the toughness reinforcing AS matrix material of above-mentioned high gloss more excellent gloss transparency and mechanical property, in a preferred embodiment, it is to adopt twin screw extruder to melt extrude that mixture melt extrudes, extrusion temperature is 170-230 ℃, screw speed 270-300 rev/min.
