Produce, generally represent color in the life with CIE1976L*, a*, the b* color space or the HunterLab color space.All colours can be used these three numeric representations of L*a*b*.Lightness index L* (luminance axis), the expression black and white, 0 is black, 100 is white, is grey between 0-100.Chromaticity index a* (red green axle), on the occasion of being red, negative value is green.Chromaticity index b * (champac axle), on the occasion of being yellow, negative value is blue.
20 ° of glossiness of pure PC resin are generally 96～97 °, add (reference examples) behind a certain proportion of carbon black and the common lubricant, and glossiness is reduced to 76.9 °.And behind the dispersion agent and lubricant with the application, glossiness is all greater than 98 °.Be all carbon black 900L though this is, lubricated and the dispersing property of common lubricant EBS can not show a candle to EFKA-4548 and BYK-9077.EBS plays inside and outside lubrication as general resin treatment auxiliary agent, improved between resin and the resin, and the oilness between resin and the screw rod, but disperse lubrication very little to the sooty of small particle size.Carbon black is bad because of disperseing, and has agglomeration, appears the surface at colour table in one's mind, and influences surface gloss.And EFKA-4585 is a kind of acrylic block copolymers, and is good with the consistency of PC resin, acts synergistically with the special-purpose wetting agent BYK-9077 of the carbon black that contains close pigment group again, through mixed at high speed, thereby obtains the high luminescent material of blacker-than-black of high dispersing.
Can be known by last table: the L* value among the embodiment is all less than reference examples, and the L* value is represented the brightness and the depth of material color.In general, the L* value is more little, and color is dark more, and is bright more, and when being black, it is shiny black more then to show as color.This has proved that also the carbon black in the embodiment material has obtained sufficient dispersion, and its colorimetric purity is fully reflected.
This shows that the blacker-than-black high gloss polycarbonate material that the embodiment of the invention provides has very significantly practical significance, excellent combination property, and outward appearance blacker-than-black, high gloss, can be used in exempt to spray, appearance component such as household electrical appliance that blacker-than-black is bright.And the preparation method of this blacker-than-black high gloss polycarbonate material is easy to operate, and material is easy to get, and technology is simple, and effect is remarkable, and tooling cost is low, and wide application prospect is arranged.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
