Coating material and preparation method thereof

Abstract

The invention provides a film plating material, which comprises a base material and a film layer plated on the base material. The film layer comprises a titanium-zirconium film layer and a titanium-zirconium nitrification film layer which are plated on the base material sequentially. The invention also provides a method for preparing the film plating material. The method comprises: a power supply is applied onto a magnetron target to make target substances on the magnetron target spatter and deposit on the base material under the condition of forming magnetron spattering of the titanium-zirconium film layer and the condition of forming magnetron spattering of the titanium-zirconium nitrification film layer sequentially, so as to form the titanium-zirconium film layer and the titanium-zirconium nitrification film layer which are plated on the base material sequentially. The target is a titanium-zirconium embedding target. The film plating material has the advantages of blue film layer, small color difference, even colors, strong metal texture of the film layer, good bonding strength, and good abrasion resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a coating material, and also relates to a preparation method of the coating material. Background technique [0002] At present, coating materials are widely used in industrial fields such as aviation, aerospace, chemical industry, shipbuilding, communication, electronics, and automobile manufacturing. Especially when applied to the decoration of electronic products, the electronic products can obtain beautiful appearance decoration and better texture, thereby increasing the value of the products. [0003] The usual coating method is to use physical vapor deposition, and the method of magnetron sputtering ion plating is especially a good coating method. The film layer prepared on the substrate has strong metal texture, good bonding force, wear resistance and durability It has excellent corrosion performance, and the thickness of the film layer is very thin, which does not affect the functions of high-end products or products wi...

Problems solved by technology

[0004] However, at present, the method of magnetron sputtering cannot obtain a blue film on the substrate.

[0005] Although, other methods can be used to obtain a blue film, such as CN1986883A discloses an environmentally friendly chromium-free conversion treatment solution, which can be used to obtain a blue film layer by using this treatment solution to carry out chemical conversion treatment on galvanized layers and zinc alloy moldings , but using this method makes the formation time of the film layer short, the stability of the film layer is not good, and the blue film layer does not have a metallic texture

In addition, spraying technology is also a commonly used method for preparing blue films, but the process of spraying technology is more complicated and polluted, and the prepared blue film does not have a metallic texture, and the thicker film layer is not suitable for high-end products or complex products. shape electronics
