Abstract
The invention discloses a halogen-free flame-retardant and cold-resistant PC/ABS (Poly Carbonate/Acrylonitrile Butadiene Styrene) material and a preparation method thereof. The halogen-free flame-retardant and cold-resistant PC/ABS material mainly comprises components of PC and ABS and further comprises a silicon fire retardant, a phosphorus fire retardant, an anti-dripping agent, a compatilizer, a flexibilizer, a lubricant, an antioxidant, and an anti-ultraviolet agent. A preparation process is a twin-screw melting extrusion pelletizing process. According to the preparation method disclosed by the invention, the silicon fire retardant and the phosphorus fire retardant are composited so that the fire resistance 1.2 mm of the obtained PC-ABS alloy material can meet the UL94V-0 class requirement in the United States. The compatilizer MBS (Methyl methacrylate-Butadiene-Styrene) not only enables the PC and the ABS to be better dissolved but also can be used for increasing the compatibility between the silicon fire retardant and a substrate. Therefore, not only can the impact property of the alloy be improved but also the flame retardant efficiency can be effectively improved. The alloy material has the good low-temperature impact property due to the flexibilizer. The silicon fire retardant has a fire retardant synergy effect and further has a smoke suppression effect, so that the fire resistance 1.2 mm of the obtained PC-ABS alloy material can meet the UL94V-0 class requirement in the United States.
Description
Technical field
The present invention relates to polymeric material field, particularly engineering plastic modification technical field, that concrete is a kind of Halogenless flaming retarding cold resistant PC/ABS material and preparation method of excellent property.
Background technology
PC is a kind of engineering plastics of excellent property, has good mechanical property, dimensional stability, thermotolerance and winter hardiness, and its shock strength is ranked first in engineering plastics; Comprehensive both advantages after PC and the ABS blend.On the one hand, it can improve thermotolerance, shock resistance and the tensile property of ABS, makes ABS be used for the high-end field; On the other hand, it can reduce the melt viscosity of PC, improves flowing of PC, improves its processing characteristics, reduces the internal stress of goods, reduces the susceptibility of shock strength to breach and thickness, makes PC can be used for the manufacturing of the long flow process goods of thin-walled.In recent years, the PC/ABS alloy is widely used on the articles for use such as mobile phone, computer casing, electrical connector.Current PC/ABS alloy has the following weak point, first: the consistency of PC and ABS is bad, causes the mechanical property of alloy monolithic not good enough; Second: flame retardant properties is bad, and the halogens too high levels, and environment is had certain contamination; The 3rd: the resistance to impact shock ability, especially when low-temperature condition, its toughness will sharply reduce, and cause material failure easily; The 4th: the ability of resistance of oxidation and ultraviolet radiation resisting, material is not high work-ing life.
Summary of the invention
The objective of the invention is to all weak points of existing P C/ABS alloy and it is carried out modification, can overcome the halogen-free flame retardant PC/ABS alloy material of weathering resistance and winter hardiness simultaneously.
The present invention for realizing the technical scheme that its purpose adopts is: a kind of Halogenless flaming retarding cold resistant PC of excellent property/ABS preparation methods is characterized in that: calculate by weight, be made up of following component:
PC resin 55.0-60.0%;
ABS resin 15.0-25.0%;
Silicon-series five-retardant 2.0-4.0%;
Phosphorus flame retardant 5.0-8.0%;
Compatilizer 2.5-5.5%;
Toughner 5.0%;
Lubricant 0.5%;
Oxidation inhibitor 0.1-1.0%;
Anti ultraviolet agent 0.1-1.0.
Described silicon-series five-retardant is Methylphenylsilanone resin PDMS or PDPS or PDPDMS.
Described phosphorus flame retardant be inorganic phosphorus such as tricresyl phosphate diformazan phenyl ester, phosphinates, melamine phosphate, phosphoric acid salt be based flame retardant, organophosphorus be in the based flame retardant any.
Said compatilizer is MBS, both can improve the impact property of alloy, can improve the oxygen index of alloy again.
Said inhibitor is that four [3-(3; The 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester and tricresyl phosphite (2; 4-di-t-butyl phenyl ester) composite mixture; The mass ratio of two kinds of compositions is 1: 1 in this mixture, a kind of in also can-3-(3-tertiary butyl-4-hydroxy-5-aminomethyl phenyl) vinyl cyanide, three (2,4-di-tert-butylphenol) phosphorous acid ester two for triglycol of said inhibitor.
Described anti ultraviolet agent is benzotriazole category or replaces triazines as light stabilizer.
Described toughner is the vinyl elastic body toughening agent E518 of maleic anhydride and TEB 3K dual graft, can improve consistency, toughness and the low temperature impact properties of alloy greatly.
The present invention has rationally adjusted the ratio of PC and ABS, can significantly improve the mechanical property of alloy, and the Halogen silicon that in alloy, adds system and phosphorus are that composite fire retardant can make the flame retardant properties 1.2mm of alloy reach the requirement of U.S. UL94V-0 level; The compatilizer MBS that adds is at the intact bonding interface of the alternate formation with ABS of PC; Make PC and the ABS can be compatible well; Compatilizer MBS can also increase the consistency between silicon-series five-retardant polysiloxane copolymer and the base material simultaneously; Both can improve the impact property of alloy, can effectively improve flame retarding efficiency again; The toughner E that adds has then improved the resistance to impact shock of alloy greatly, makes alloy under the low temperature of-35 degree, still have toughness preferably; The adding of inhibitor and anti ultraviolet agent makes the PC/ABS alloy have the ability of resistance of oxidation and ultraviolet radiation resisting preferably again, thereby guarantees the work-ing life of material.
The present invention has also designed a kind of Halogenless flaming retarding cold resistant PC/ABS preparation methods of excellent property, may further comprise the steps:
1) takes by weighing material by prescription;
2) material is poured in the agitation vat stirred 5-10 minute, mixing speed is 300-450 rev/min;
3) mixed raw materials is put into twin screw extruder and melt extrude granulation, complete processing is following: twin screw extruder one district 220-230 ℃, two district 235-240 ℃, three district 235-240 ℃, four district 235-240 ℃, five district 240-250 ℃, six district 245-250 ℃, seven district 240-245 ℃, eight district 235-240 ℃; Screw speed 300-450 rev/min.
Benefit of the present invention is:
1) the present invention is through the fire-retardant requirement of the composite realization of halogen-free flame retardants PC/ABS material;
2) the present invention makes that the physical and mechanical properties of PC/ABS material is excellent, weathering resistance and low temperature impact properties be good.

Performance evaluation criterion and performance index
The particle material that aforesaid method is accomplished granulation in convection oven under 90 ℃ the condition dry 3-5 hour earlier uses the particle material that drying is good to process the batten test with injection moulding machine then.
The performance of embodiment and Comparative Examples is respectively like table 1 and table 2:
Table 1
During top shock strength is under the condition of V mouth, to measure.
Table 2
During top shock strength is under the condition of V mouth, to measure.
Associative list 1 can be found out with table 2; Use silicon-series five-retardant or phosphorus flame retardant all can't make flame retardant properties reach the requirement of U.S. UL94V-0 level separately; Through flame-retardant system composite we find all can reach fire-retardant requirement, and silicon-series five-retardant is less to other performance impacts of alloy, but phosphorus flame retardant has certain influence; In addition, compatilizer helps improving the intensity and the flame retardant resistance of alloy.
