Description
Technical field
The invention belongs to resin formula and preparation field thereof, especially relate to a kind of improve outward appearance exempt from spraying aesthetic resin and preparation method thereof.
Background technology
Along with the popularization of low-carbon environment-friendly concept, substitute the spraying aesthetic resin of exempting from that sprays paint and more and more receive numerous enterprises man and public concerns, demonstrate the unprecedented market competitiveness.The special-effects such as the gorgeous colorful tone that not only can reaching sprays paint produces and pearly-lustre, flash effect, metal color can also realize the effect that the metals such as semi-transparent, full impregnated and astigmatism do not reach.The plastics of common prepared aesthetic resin have PP, ABS, PMMA, ABS/PMMA, PC, PC/ABS, ASA, polyester, PS etc.Aesthetic resin not only production efficiency is high, and cost is low, and can recycle, and is widely used in the fields such as household electrical appliances, automobile, consumer electronics.
Exempting from spraying aesthetic resin compares with the material that sprays paint, although holistic cost is lower, but the toner of the special-effect of using is more, exempt from spraying aesthetic resin integral body and all contain the toner of special-effect, and determine that the toner that the just toner of resin surface layer of product outward appearance, major part are in resin inside all is wasted; On the other hand, in order to increase the effect of exempting from spraying aesthetic resin, just need to strengthen the consumption of toner, so just increased the weight of the defectives such as current mark that the flow orientation difference due to metallic pigment or pearly pigment causes and weld bond, limited the effective scope of exempting from spraying aesthetic resin.

Embodiment 4, compliance test result
Table 1 is for using embodiment 1,2,3 and Comparative Examples 1,2 the prepared injection moulding colour table of material, and the processing conditions of extruding batten of embodiment 3 and material characteristics etc., and table 2 is the such scheme opacity, improve the description of effect and current mark.
By table 1,2 as can be known, with embodiment 1,2 relatively, find the increase along with ferroferric oxide magnetic powder, opacity and the flicker effect on product surface are stronger, and this is the cause that increase due to particle content makes aluminium powder strengthen to the mobility on product surface.
Comparative example 2 and 3, opacity and the flicker effect of finding embodiment 3 products are stronger, and this is because cobalt-iron oxide magnetic powder is stronger than ferroferric oxide magnetic powder paramagnetism, more easily causes the migration of aluminium powder, make opacity and the flicker effect on surface stronger, current mark is also slighter.
Comparative example 3 injection moulding colour table and extrude batten (extruding soon), opacity and flicker effect that batten is extruded in discovery are stronger, and current mark is lighter, this is because compare with injection moulding process, the extrusion time used is longer, and the migration of magnetic aluminium powder pigment is more abundant, and surface sediment is more closely knit, and orientation is better, is difficult for producing current mark.When the extruded velocity of adjusting batten is adjusted to 1m/min by 2m/min, opacity and the flicker effect of finding to extrude at a slow speed spline surfaces are stronger, and this is because extrusion magneticmetal pigment migration is more abundant at a slow speed.
Comparing embodiment 1 and Comparative Examples 1 are found identical content of aluminium powder, and system opacity and the flicker effect of adding magnetic are stronger, and current mark is also slighter.Comparing embodiment 1 and Comparative Examples 2 find that the nonmagnetic powder system wants covering and the flicker effect that reaches consistent with the magnetic system, need to add more metal toner, and be much serious but the current mark of product is wanted.
