Abstract:
(EN) Disclosed in the present invention are a tungsten oxide-mica photochromic pearlescent pigment and a preparation method for a dispersion liquid thereof, belonging to the field of preparation of novel functional materials. In the present invention, in order to overcome the deficiencies of the prior art, tungsten oxide is uniformly coated on the surface of the mica by means of the assistance of a water-soluble organic material and the adjustment of the pH, thereby preparing a tungsten oxide-mica photochromic pearlescent pigment. The obtained powder or a dispersion liquid thereof is directly exposed to ultraviolet light for different lengths of time to observe photochromic effects, and it is found that the prepared powder and dispersion liquid both exhibit good photochromic effects under ultraviolet light irradiation, the light response speed and photochromic reversibility being good. The method in the present invention is a low temperature chemical synthesis method, being mild, simple, efficient, and easy to industrialize.
(FR) La présente invention concerne un pigment nacré photochromique d'oxyde de tungstène-mica et un procédé de préparation d'un liquide de dispersion de celui-ci, appartenant au domaine de la préparation de nouveaux matériaux fonctionnels. Dans la présente invention, afin de surmonter les déficiences de l'état de la technique, de l'oxyde de tungstène est uniformément revêtu sur la surface du mica au moyen de l'assistance d'un matériau organique soluble dans l'eau et de l'ajustement du pH, ce qui permet de préparer un pigment nacré photochromique d'oxyde de tungstène-mica. La poudre obtenue ou un liquide de dispersion de celle-ci sont directement exposés à une lumière ultraviolette pendant différentes durées pour observer des effets photochromiques, et on a remarqué que la poudre et le liquide de dispersion préparés présentent tous deux de bons effets photochromiques sous irradiation de lumière ultraviolette, la vitesse de réponse à la lumière et la réversibilité photochromique étant bonnes. Le procédé selon la présente invention est un procédé de synthèse chimique à basse température, et est un procédé à conditions modérées qui est simple, efficace et facile à adapter à une production industrielle.
(ZH) 本发明公开了一种氧化钨-云母光致变色珠光颜料及其分散液的制备方法,属于新型功能材料制备领域。为了克服现有技术的不足,本发明通过水溶性有机物的辅助以及pH的调整将氧化钨在云母表面均匀包覆,从而制备得到氧化钨-云母光致变色珠光颜料。将所得粉体或其分散液直接置于紫外灯下照射不同的时间观察其光致变色效果,发现制备得到的粉体及分散液在紫外灯照射下均呈现出良好的光致变色效果,其光响应速度且光致变色可逆性好。本发明中的方法为低温化学合成法,温和、简单、高效、易于工业化放大。
