Embodiment 1

[0020] The product to be coated is subjected to five layers of optical coating in the optical coating device: the first layer of Tio 2 Coating, second layer SiO 2 Coating, the third layer of TiO 2 Coating, fourth layer SiO 2 Coating, the fifth layer of TiO 2 coating.

[0021] The optical coating device includes a vacuum coating chamber, 2 crucibles and 2 electron guns. Before coating, put the product to be coated into the vacuum coating chamber, seal the vacuum coating chamber, and vacuum the vacuum coating chamber to achieve a vacuum pressure of 3.0×10 -3 Stop vacuuming after pa. Inflate the vacuum coating chamber with an oxygen flow rate of 15 sccm, an argon flow rate of 8 sccm, and a vacuum pressure of 1.5×10 -2 pa. When the coating starts, the current of the ion source in the vacuum coating chamber is 3A, and the ion source plays the role of assisting the evaporation of the crucible evaporation source to enhance the effect of optical coating.

Abstract

The invention belongs to the technical field of surface processing, in particular to a method for preparing high metallic texture high transmission lens. The method comprises the following: step one, optical filming: a product to be filmed is subjected to five-layer optical filming in an optical filming device; wherein the first layer is TiO2 filming; the second layer is SiO2 filming; the third layer is TiO2 filming; the fourth layer is SiO2 filming; the fifth layer is TiO2 filming; step two, priming coat spraying: priming coat is sprayed on the surface of the product filming to be roasted in an oven; step three, UV finishing coat spraying: the UV finishing coat is sprayed on the surface of the product filming to be roasted by the oven and solidified by a UV furnace. The plastic lens processed by the method has strong metal texture, friction and scratch resistance and high transmission rate reaching 98 percent.

Description

Technical field: [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a method for preparing a lens with high metallic texture and high light transmission. Background technique: [0002] With the development of technology, the market competition of consumer electronic products is becoming more and more fierce. In order to attract consumers to purchase electronic products, in addition to the functions of the product, the appearance of the product has become one of the key factors for the success of the product. Commonly used consumer electronic product casings are often made of plastic, and the surface of untreated product casings is rough and dull, which affects the appearance of the product. Abrasion resistance is also important because consumer electronics are often touched. In addition, the product casing also needs to withstand a certain impact force, so that the appearance of the product will not be damaged due to acci...
