Description

A kind of low temperature resistant, acid/alkali-resistant, HI high impact ABS and preparation method thereof
Technical field
The present invention relates to alloy preparation technology field, more particularly to a kind of ABS preparation technology field.
Background technology
ABS has excellent physical and mechanical properties at normal temperatures as a kind of general-purpose plastics, is widely used very early In fields such as household electrical appliance, automobiles.But the structure of ABS itself also causes that the material has many shortcomings, such as molten intolerant to oils Agent, the short time is to ftracture after contact；Acid and alkali-resistance, does not understand swelling corrosion after immersion；Low-temperature impact is also more general etc.；Because There is undersaturated carbon-carbon double bond in ABS so that the material is easy to oxidation jaundice, ultimately results in material embrittlement, and these are all limited The extensive utilization of the material.
Although common PC/ABS alloy low-temperature impacts are higher, cannot still improve the defects such as oil resistant, acid and alkali-resistance；ABS/ PA alloys can improve oil resistant and resistance to alkalescent, but mechanical property is influenceed by very big；Though the ABS/PC/PBT of common process production Oil resistant and acid and alkali-resistance can so be improved, but because of the ester exchange of PC and PBT, cause unstable properties, and because styrene-propene The addition of nitrile-GMA, causes crosslink material serious, and mobility declines to a great extent, inconvenient injection molding, There is wretched insufficiency.
The content of the invention
To solve problem above, the present invention provides a kind of low temperature resistant, acid/alkali-resistant, HI high impact ABS, and its feature exists In the composition including following weight portion：ABS 40-60 parts, PC 8-15 parts, PBT 15-30 parts, styrene-acrylonitrile-first 3-6 parts of base glycidyl acrylate, methyl-silicone oil 1-2 parts, 5-15 parts of MBS toughener, triphenyl phosphate 1-3 Part, 0.5-1 parts of other processing aids.
Preferably, other processing aids are cured to cover denier.
This low temperature resistant, acid/alkali-resistant, HI high impact ABS, its preparation method are as follows：
（1）Baking material：ABS dries 1-2 hours under 85-95 degree, PC, PBT baking material 4 hours under 125 degree；
（2）High-speed stirred：PC and PBT is first poured into, adds methyl-silicone oil to stir 1 minute；Add triphenyl phosphate high-speed stirred To 120 degree, triphenyl phosphate is become pasty state and stick to particle surface, add ABS stir 3 minutes, add styrene- Acrylonitrile-methacylate ethylene oxidic ester, MBS toughener and other auxiliary agents are stirred 1-2 minutes；
（3）Extrusion：Extruded using corotating twin-screw, temperature setting range 220-250 degree, engine speed 450-600 turns, spiral shell Bar selects low sheraing polymolecularity screw combinations；
（4）Cooling, blank：Using water-cooled and it is air-cooled cooled down, and use planer-type pelleter pelletizing, particle size is 3* 3mm；
（5）Packaging.
The invention has the advantages that：Using this ABS naval stores good fluidity, the Yi Jia for being formulated and making Work, the heat distortion temperature compared with ABS material is high.The addition of PBT causes that material is provided with preferable oil resistivity and certain resistance to acids and bases, The ester of the addition double inhibition of methyl-silicone oil and styrene-acrylonitrile-GMA PC and PBT is handed over Change, make PC, PBT, ABS in cross-linked network, improve the rigidity and impact strength of material, and the addition energy of triphenyl phosphate Prevent mobility caused by PC that styrene-acrylonitrile-GMA causes and PBT excessively crosslinkings Difference so that mobility is higher, it is easy to injection molding.The mixing procedure that the preparation technology of present invention offer simultaneously is more conventional is complicated, Being primarily due to ABS and PC has certain compatibility, and styrene-acrylonitrile-GMA both may be used To improve the compatibility of ABS and PC, it is also possible to improve the compatibility of ABS and PBT, PBT and ABS, so three components are easily on boundary Entanglement is produced on face, causes interfacial instability, unstable properties.So this technique first makes full use of limited compatible of PC and PBT Property, faint compatible interface is produced at 135 degree or so, then based on ABS, cause PC and PBT individually respectively and ABS phases Hold, form main interface, main interface and faint interface form conjugated structure so that whole system is more stable, reliable.
