[technical field]
The present invention relates to macromolecular material, particularly relate to a kind of ABS/PA6 magnetic composite and preparation side thereof
Method.
[background technology]
ABS (acrylonitrile butadiene styrene terpolymer) resin is polymerized by three kinds of monomers, and third
Alkene nitrile component gives ABS resin certain chemical stability, oil resistivity and certain rigidity and hardness；Fourth two
Alkene gives again its good toughness, impact and tolerance to cold；Styrene then makes it have good dielectric properties,
And present good processing characteristics.Therefore, ABS resin has excellent mechanical property tough, hard, that just equalize mutually concurrently
Can, being that current world wide is interior applies one of most commonly used plastics.But ABS resin there is also resistance toization simultaneously
The deficiency that the property learned, oil resistivity and weatherability are poor, limits the use of ABS resin to a certain extent.
PA6 (polycaprolactam) resin is the polymer of a kind of partially crystallizable, has good wearability, resistance to
Chemical and oil resistivity, PA6 resin weatherability is excellent simultaneously, mechanical strength is high, is widely used in automobile
The industries such as parts, mechanical part, instrument, instrument and packaging, but the hygroscopicity of PA6 resin is big, room temperature

Work and outward appearance, can be widely applied to the fields such as household electrical appliances, electronic apparatus, automobile, widened ABS greatly
And the range of PA6.
The more traditional ferrite sintered magnet of magnetic plastics is lightweight, impact resistance, compact dimensions precision are high, quilt
It is considered a kind of and uses the most excellent magnet flexibly.Magnetic plastics after developing the nineties in 20th century,
Owing to having plastics and magnetic material concurrently, and compared to the unworkability of traditional ferrite sintered magnet,
Magnetic plastics can use the general processing method of general plastics (as injected, molding, extrusion etc.) to be processed,
Application prospect is boundless.But, general magnetic powder is mineral-type materials, poor with Compatibility in Plastics, system
After standby one-tenth composite, mechanical performance is poor, it is difficult to meets and uses requirement, have impact on ABS/PA6 alloy magnetic
Composite is applied.
