Description

A kind of flame-retardant ABS compound material and preparation method thereof
Technical field
The invention belongs to technical field of polymer materials, particularly relate to a kind of flame-retardant ABS compound material and system thereof Preparation Method.
Background technology
Propylene is fine-and SB (ABS) is one of five big synthetic resin, and it has well Processing characteristics, be widely used in material processing field, but ABS anti-flammability be poor, and burning time Caloric value is big, can produce substantial amounts of molten drop, flame propagation speed, is difficult to extinguish.So to fire line When the field that can have certain requirements uses, it is necessary to ABS is carried out flame-retardant modified.
For current fire retardant, mainly there is halogen fire-retardant and the big class of halogen-free flameproof two.Practical study and should In with, in order to while reaching preferable flame retardant effect, the consumption of main flame retardant to be reduced, often Add anti-dripping agent use compounding with main flame retardant in the polymer, so can play preferable effect.Mesh Front anti-dripping agent is the most almost all fluorinated anti-dripping agent (such as politef).
In order to improve the performance of ABS, now use in some composites of ABS material, be all by with its The materials such as its material such as PC, PVC are used in mixed way, and such as CN201310482863.2 discloses a kind of high The ABS alloy material of toughness, wherein the consumption of ABS is 50-60%；CN201310559219.0 discloses A kind of electric appliance casing is material modified, and wherein the consumption of ABS is 65-80%；CN201310212190.9 is open A kind of ABS is combined the high-ductility alloy material of PC, and wherein the consumption of ABS is 35-47%； CN201410370306.6 discloses a kind of high rigidity electrical equipment plastics, and wherein the consumption of ABS is 25-36%.
In these technology, all employ other macromolecular material in addition to ABS, hope with it and form bone with ABS Shelf structure, but found by research, and using composite prepared by multiple macromolecular material, it is to rigidity Raising inconspicuous, and anti-anti-flammability does not the most improve, and still needs to add in the composite big The fire retardant of amount, and because a large amount of uses of fire retardant, cause the rigidity of composite and mobility to be all subject to To impact.The rigidity of the most existing macromolecular material is dependent on sacrificing the mobility of composite and realizes, And if realize composite and i.e. there is certain rigidity ensure certain mobility, just must be at composite The macromolecular material that middle interpolation mobility is high, and the rigidity of the high material of mobility is the highest, this is this area skill Art personnel the most clearly problem.
Summary of the invention
It is an object of the invention to provide a kind of flame-retardant ABS compound material and preparation method thereof, to solve existing skill Art needs substantial amounts of fire retardant and needs multiple macromolecular material while realizing composite high rigidity Ensure again the contradictory problems of certain fluidity.
The present invention is achieved by the following technical solutions:
A kind of flame-retardant ABS compound material, its composition by weight,
The draw ratio of described needle-like nano calcium carbonate is 8:1-16:1, and particle diameter is 2500-3000 mesh.
Described fire retardant is that TDE, eight bromine bisphenol S ethers, antimony oxide, Halogen nitrogen phosphorus are fire-retardant One or more combinations in agent MELAPUR200-70.
Described antioxidant is three (2,4-di-t-butyl) phenyl-phosphite, four [β-(3,5-di-t-butyls -4-hydroxy phenyl) propanoic acid] pentaerythritol ester and 1,3,5-trimethyl-2,4,6-(3,5-bis-tertiary fourths Base-4-hydroxyphenylmethyl) combination of one or more in benzene.
Described lubricant is the one in ethylene bis stearamide or dimethicone.
The steady agent of described light is 2-(2-hydroxyl-5-t-octyl phenyl) benzotriazole.
The preparation method of the described flame-retardant ABS compound material of any of the above-described item, comprises the following steps:
1) by set proportioning choose ABS, fire retardant, needle-like nano calcium carbonate, antioxidant, lubricant and Light stabilizer；
2) by step 1) component by homogenizer stir 10-12min, formed mixed material, its The whipping temp of high speed blender is 70-120 DEG C, rotating speed 120～240r/min；
3) by step 2) in mixed material by double screw extruder, after frit reaction, by squeezing Go out pelletize, cooling, pelletizing and be dried prepare flame-retardant ABS compound material.
Described double screw extruder comprises seven districts, and the most each district temperature and screw speed are respectively as follows: district's temperature Spend 190～210 DEG C, two district's temperature 230～270 DEG C, three district's temperature 230～270 DEG C, four district's temperature 230～ 270 DEG C, five district's temperature 230～270 DEG C, six district's temperature 230～270 DEG C, head temperature 230～270 DEG C； Screw speed 200～260r/min.
Described it is cooled to water cooling.
The invention have the benefit that
The flame-retardant ABS compound material use needle-like nano calcium carbonate of the present invention is as anti-dripping agent, with traditional Anti-dripping agent such as politef is compared, because the draw ratio of needle-like nano calcium carbonate is 8:1-16:1, And particle diameter is 2500-3000 mesh, the good dispersion in ABS, carry out melt extruded at double screw extruder Time, needle-like nano calcium carbonate can be overlapped to form network structure, and this network structure is prevented from the effect of flame drippage.
Another aspect of the present invention, by the anti-drip effect of needle-like nano calcium carbonate, reduces flame-retardant device Usage amount, while having saved material, it is ensured that flame retardant effect, and uses the rigidity of composite to obtain To raising in various degree, and the mobility of the composite ensured.
Another aspect of the invention is, uses single ABS material, it is possible to the characteristic of prominent ABS.
