Embodiment Construction

[0010] The printing method for forming trademarks or patterns on the housing in a preferred embodiment of the present invention includes the following steps:

[0011] A metal case is provided. The material of the metal shell is aluminum or aluminum alloy. The metal casing can also be anodized to form an anodized film layer.

[0012] A first ink layer is formed by printing on the metal shell or the anodized film layer of the metal shell, and the printing method is screen printing. The first ink layer may be a trademark of a product, or a symbolic pattern of a product. The ink for printing the first ink layer is a mixture of the first main agent, the second main agent, curing agent and diluent, and the ink is configured as follows:

[0013] The first main agent and the curing agent are prepared at a mass ratio of 7:3 to obtain a first intermediate ink, and then the second main agent is added to the first intermediate ink for preparation to obtain a mixed ink. The mass percen...

Abstract

The invention provides a printing method for forming a trademark or a pattern on a shell. The method comprises the following steps of: providing a metal shell; printing a first printing ink layer on the metal shell and drying the first printing ink layer for 15 to 25 minutes at the temperature of between 100 and 150 DEG C, wherein the first printing ink layer comprises an epoxy resin; printing a second printing ink layer on the first printing ink layer and drying the second printing ink layer for 15 to 25 minutes at the temperature of between 100 and 150 DEG C, wherein the second printing ink layer comprises an epoxy resin; and printing a third printing ink layer on the second printing ink layer and drying the third printing ink layer for 60 to 120 minutes at the temperature of between 100 and 150 DEG C, wherein the third printing ink layer comprises an epoxy resin.

Description

technical field [0001] The invention relates to a printing method for forming trademarks or patterns on a casing, in particular to a printing method for forming friction-resistant trademarks or patterns on a casing. Background technique [0002] Existing electronic products usually have product trademarks or patterns on their housings. A commonly used method for setting the trademark or pattern is screen printing. Since the trademark or pattern is printed on the casing, it is often rubbed by external objects during use, so the printed trademark or pattern is required to have strong friction resistance. The existing trademarks or patterns printed on the housing usually have the defect of low friction resistance and are easy to be rubbed off, thus affecting the appearance and use value of the product. Contents of the invention [0003] In view of this, it is necessary to provide a printing method for forming a friction-resistant trademark or pattern on the casing. [0004...
