Abstract
The utility model discloses a high steady anti-yellowing pearl pigment, which structurally comprises a sheet base material, a titanium dioxide thin membrane and an anti-yellowing protective layer, wherein the titanium dioxide thin membrane is wrapped on the surface of the sheet base material; and the anti-yellowing protective layer is wrapped at the outmost layer. In the anti-yellowing pearl pigment, an insulating protective layer is wrapped outside a titanium dioxide membrane layer so that the yellowing phenomena of printing ink, plastic and dope are reduced well during the application process, simultaneously the stability of pigment and color is improved, the application level of a pearl pigment within the industry can be improved, and the high steady anti-yellowing pearl pigment has strong practicality and extensive applicability.
Description
Technical field
This practical pearly pigment that relates to a kind of anti-discolouring particularly a kind ofly can resist xanthochromic novel macreous pigment in the application of plastics, printing ink etc.
Background technology
Common pearly pigment is to make at the oxide film of high refractive index such as flat substrates surface cladding titanium dioxide.This oxide compound has photochemical activity, and under the action of ultraviolet ray in light, the Sauerstoffatom in the titanium dioxide lattice can absorb the energy of photon h υ, discharges idea and brings out the reaction of a series of redox chemistries.Also can emit nascent oxygen simultaneously,, will cause in the macromolecular chain fracture of two keys and degraded and oxidizing reaction take place in case these nascent oxygen atoms contact with resin one class high polymers matter with very strong oxidation capacity.And the oxygen of this status nascendi and the redox reaction between the high molecular polymer hocket repeatedly, net result is that resin coating film, printing ink or plastics are occurred such as phenomenons such as loss of gloss, flavescence and efflorescence, and institute is so that common pearly pigment is limited in application.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can resist xanthochromic pearly pigment in the application of plastics, printing ink etc.
The utility model is achieved by the following technical programs:
A kind of high stable state resists xanthochromic pearly pigment, and its structure is followed successively by flat substrates layer, titanium deoxid film, silica membrane from the inside to the outside.
Wherein, can before the cladding titanium dioxide film, coat one deck tin dioxide thin film at the flat substrates laminar surface earlier.The flat substrates layer is a kind of of mica, synthetic mica or glass flake.
Silica membrane has the function of blocking with shielding ultraviolet rays; the photochemical activity of titanium deoxid film is reduced; so can play the effect of protective membrane; silica membrane is kept apart titanium dioxide active centre and high molecular polymer, makes high molecular polymer not react and produce xanthochromia with the active ion of titanium dioxide.Simultaneously in order to improve stability, use adjust agent for example rutile-type promotor mixes with silica membrane, make that silica membrane is even, densification, the complete outermost layer that is coated on the flat substrates layer.
The utility model usefulness is:
The utility model coats one deck isolated protective layer again outside titanium oxide film layer; in application, can well reduce the xanthochromia phenomenon of printing ink, plastics, coating; also improved the stability of pigment color simultaneously; can promote pearly pigment application level in industry, possess splendid practicality and applicability widely.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment one:
As shown in Figure 1, a kind of high stable state in the present embodiment resists xanthochromic pearly pigment, and its structure is followed successively by flat substrates layer 1, titanium deoxid film 2, silica membrane 3 from the inside to the outside.
In concrete implementation procedure, keep the pH value of the solution of flat substrates formation to stablize down 65 ℃～75 ℃ of comparatively high tempss, then cladding titanium dioxide film 2 and mixed the silica membrane 3 of red stone type promotor successively, at last by stir, filter is done, after the deionized water washing, oven dry, incinerating process, promptly obtain anti-xanthochromic pearly pigment finished product.
Embodiment two:
As shown in Figure 2, a kind of high stable state in the present embodiment resists xanthochromic pearly pigment, and its structure is followed successively by flat substrates layer 1, tin dioxide thin film 4, titanium deoxid film 2, silica membrane 3 from the inside to the outside.
In concrete implementation procedure, keep the pH value of the solution of flat substrates formation to stablize down 75 ℃～85 ℃ of comparatively high tempss, then coat tin dioxide thin film 4, titanium deoxid film 2 successively and mixed the silica membrane 3 of red stone type promotor, at last by stir, filter is done, after the deionized water washing, oven dry, incinerating process, promptly obtain anti-xanthochromic pearly pigment finished product.
Claims (3)
