Problems solved by technology

[0002] With the advancement of technology and the development of technology, people have higher and higher requirements for the appearance and decoration effect of materials. The appearance decoration of a single color can no longer meet the needs of users, and the appearance decoration effect of materials is developing towards diversification.
[0003] The existing technology can deposit a color layer on the surface of the substrate through physical vapor deposition (PVD), but it cannot achieve a colorful effect (the color is different from all directions); while the non-conductive plating technology (NCVM) forms a coating on the surface of the substrate, although it can Achieve glare effect, but the bonding force between the coating and the substrate is small, and part of the coating is easy to peel off from the surface of the substrate during use

preparation example Construction

[0034] The second aspect of the present invention provides a method for preparing a decorative material, providing a substrate; forming a transition layer on one side of the substrate; forming a color layer on the side of the transition layer away from the substrate; forming a connecting layer on the side of the color layer away from the transition layer Form the coating layer on the side of the connection layer away from the color layer; Wherein, the coating layer includes multiple sub-coating layers stacked in sequence, and the sub-coating layer close to the connection layer in the multi-layer sub-coating layer is the first sub-coating layer Coating layer, the thermal expansion coefficient of the first sub-coating layer is 3×10 -6 / K-6×10 -6 / K, the thermal expansion coefficient of the connecting layer is 5×10 -6 / K-10×10 -6 / K, and the thermal expansion coefficient of the first sub-coating layer is smaller than the thermal expansion coefficient of the connecting layer. T...

Embodiment 1

[0041] Decorative materials, including: aluminum alloy substrates stacked in sequence, Ti metal transition layer (thickness 30nm), TiSi transition layer (thickness 600nm), TiSiC color layer (thickness 1μm), SiO 2 Connection layer (thickness 30nm), SiO 2 The first sub-coating layer (thickness is 10nm), Ti 3 o 5 Coating layer (thickness 20nm), SiO 2 Coating layer (thickness 20nm), Ti 3 o 5 Coating layer (thickness 40nm), SiO 2 Coating layer (thickness 30nm), Ti 3 o 5 film layer (thickness 20nm) and anti-fingerprint layer, in which SiO 2 The thermal expansion coefficient of the connection layer is 6×10 -6 / K, SiO 2 The thermal expansion coefficient of the first sub-coating layer is 5×10 -6 / K;

[0042] Preparation process of decorative materials:

[0043] (1) Provide aluminum alloy substrate;

[0044] (2) A Ti metal transition layer with a thickness of 30nm is formed on the surface of the aluminum alloy substrate by physical vapor deposition. During the deposition pr...

Embodiment 2

[0051] The structure and preparation process of the decoration material in this embodiment are basically the same as in Example 1, the difference is that the Ti metal transition layer is replaced by a Cr metal transition layer, the TiSi transition layer is replaced by a CrSi transition layer, and the TiSiC color layer is replaced by a CrSiN color layer .

Abstract

The invention provides a decorative material. The decorative material comprises a base body, a transition layer, a color layer, a connecting layer, and a coating layer, wherein the transition layer is arranged on one side of the base body; the color layer is arranged on the side, away from the base body, of the transition layer; the connecting layer is arranged on the side, away from the transition layer, of the color layer; the coating layer is arranged on the side, away from the color layer, of the connecting layer; and the coating layer comprises multiple sub-coating layers which are sequentially stacked, the sub-coating layer, close to the connecting layer, in the multiple sub-coating layers is the first sub-coating layer, the thermal expansion coefficient of the first sub-coating layer is 3*10<-6> / K-6*10<-6 > / K, the thermal expansion coefficient of the connecting layer is 5*10<-6> / K-10*10<-6> / K, and the thermal expansion coefficient of the first sub-coating layer is less than that of the connecting layer. Through the above arrangement, the decorative material can achieve the colorful effect, and meanwhile, the binding force between the layers of the decorative material can be guaranteed, and the problem that the film layer falls off in the using process is solved.
