Abstract
The invention discloses a color-changing shimmer pigment having 3D (Three-Dimensional) effect and changing color with angle, which belongs to multi-coating technology. A plurality layer of oxides wrap on a substrate to form the color-changing shimmer pigment the color of which can be changed along with change of angles according to different refractive indexes of the oxides, then, a bivalent iron salt and a ferric iron salt which serve as modification materials wrap on the surface of the color-changing shimmer pigment so that the pigment is in a three-dimensional effect under the action of an external force, the surface layer of the pigment is treated by Na2SiO3 to prevent the bivalent iron from being easily oxidized, oxides with high refractive indexes wrap on the first layer and the third layer of the substrate in a water environment through a liquid phase deposition method, an oxide with a low refractive index wrap on the second layer, the fourth layer is modified by the bivalent iron salt (Fe<2+>) and the ferric iron salt (Fe<3+>), and Na2SiO3 serving as a protective layer wrap on the fifth layer; finally, the 3D color-changing shimmer pigment with high three-dimensional effect and high saturation degree is formed.
Description
Technical field
The present invention relates to a kind of pearly pigment, is to allow ordinary two dimensional color pearly pigment be converted into the effect pigment with three-dimensional space and changeable colors along with angle.
Background technology
On current market, people buy the consumer's goods, and except watching the performance of product, the beautiful degree of outward appearance also becomes the emphasis that people pay close attention to.A large amount of decoration etc. beautifies industry and continues to bring out in recent decades thus, as wallpaper, coating, makeup, artificial marble, automobile finish, printing, plastics etc.Pearly pigment also enters all trades and professions rapidly as a kind of physics, chemically stable effect pigment, and becomes the focus that each businessman pursues and innovates.The use range of pearly pigment is increasing at present, has been penetrated into us and has lived in required every article: as the shining point of the top coat of the shell of power truck, automobile, umbrella, clothes, case and bag, cap top; The finishing materials such as wallpaper, floor, ceramic tile; Refrigerator, washing machine, air-conditioning, the shell of the household electrical appliance such as switch of power supply even; Eye shadow, lipstick, body wash, shampoo makeup; The high-grade articles for use such as mobile phone, computer, phone, toy.
The development of pearly pigment has also obtained comprehensive progress, and from the silvery white pearly pigment starting most, interference finally series, iron is serial, gold is serial, variable color is serial.The research staff of each enterprise, by use different method for coating and different coated thickness with metal oxides such as titanium dioxide, ferric oxide, has produced the pearly pigment of thousands of kinds of models.Again by coated metal oxide on different substrate materials, crystal series, the serial product of diamond have been formed nearly ten years.
Even if increasing product offers us, these products are still difficult to meet the pursuit that people are more and more higher.From two dimensional surface to 3 D stereo, be wherein one of to pursue, as people in recent years like picture relief painting, buy three-dimensional picture, picture frame on market also has with stereoeffect.From the purity of pursuing color to the magic variation of pursuing color.But common pearly pigment physics, chemical property are too stable, and the effect that can only show two dimensional surface does not possess relief drawback, makes the magnetism of product application be subject to limitation.Therefore, produce the pearly pigment that three-dimensional space has again the function of changeable colors along with angle simultaneously, become the direction that we study new color.
