Abstract

The invention discloses a method for multi-color laser engraving on the surface of a silicone key. After the laser engraving process is completed, two colors of ink A and ink B can be embodied in the same area. The method is produced by the following steps: directly spraying a base color ink A to be embodied on a product, keeping it warm for 1 hour at a temperature of 210 degrees for vulcanization; spraying an additional layer of dark ink C on the base color ink A, keeping it warm for 1 hour at a temperature of 200-220 degrees for vulcanization; spraying another layer of base color ink B, keeping it warm for 1 hour at a temperature of 200-220 degrees for vulcanization; finally spraying a required surface ink color D, keeping it warm for 1 hour at a temperature of 200-220 degrees for vulcanization; during laser engraving, adjusting the machine power (9W) to first remove the surface ink D and expose the required color of the ink B; then adjusting the laser engraving machine power (17W) to remove the surface ink D, ink B and dark ink C, exposing the color of the ink A, and forming a multi-color laser engraving without boundary marks on the surface of the silicone key.

Description

A method for multi-color laser engraving on the surface of a silicone button

technical field

The invention relates to a method for making a silica gel key, in particular to a method for multi-color laser engraving on the surface of the silica gel key.

Background technique

In the existing technology, when making silicone buttons, it can only be done after laser engraving in the same area on the surface of the product, and the exposed color of the bottom layer can only be white or a single color; to reflect multiple colors, printing technology is required. The printing process has the following disadvantages: the printing process has the problem of position accuracy in the same area, and it is impossible to ensure 100% matching on the color boundary marks.

Contents of the invention

The purpose of the present invention is to provide a method for multi-color laser engraving on the surface of a silicone keypad. This method can achieve multi-color laser engraving in the same required area without boundary marks, and fundamentally solve the problem of boundary marks.

Provide a method for multi-color laser engraving on the surface of the silicone button. After the laser engraving process is completed, the two colors of ink A and B can be reflected in the same area. The following steps are used to produce:

Spray the base color ink A that needs to be reflected directly on the product, and keep it at 200-220 degrees for 1 hour to vulcanize;

Spray a layer of dark ink C on the base color ink A, and heat it at 200-220 degrees for 1 hour to vulcanize;

Then spray a base color ink B, keep it at a temperature of 200-220 degrees for 1 hour to vulcanize; finally spray the required surface ink color D, and keep it at a temperature of 200-220 degrees for 1 hour to vulcanize;

When laser engraving, adjust the power of the machine to 8-10W, remove the surface ink D first, and expose the color of ink B required;

Then adjust the power of the laser engraving machine to 16-18W, and then remove the surface ink D, ink B and dark ink C to expose the color of ink A, and form a multi-color laser engraving on the surface of the silicone button.

The present invention has the following advantages: by adopting the multi-color laser-engraved silicone keypad produced by multiple spraying processes and two-time radium-engraving processes, multi-color laser-engraving can be realized in the same area as required without border marks, thereby solving the problem of the junction problem of marks.

Detailed ways

The two colors of ink A and B are reflected in the same area, and the following steps are used to make it:

Spray the base color ink A that needs to be reflected directly on the product, and keep it at 210 degrees for 1 hour to vulcanize;

Spray a layer of dark ink C on the base color ink A, and heat it at 210 degrees for 1 hour to vulcanize;

Then spray a base color ink B, and keep it at 210 degrees for 1 hour to vulcanize; finally spray the required surface ink color D, and keep it at 210 degrees for 1 hour to vulcanize;

When laser engraving, adjust the power of the machine (9W), remove the surface ink D first, and expose the required color of ink B;

Then adjust the power of the laser engraving machine (17W), and then remove the surface ink D, ink B and dark ink C to expose the color of ink A, and form a multi-color laser engraving on the surface of the silicone keypad without border marks.

Claims (1)

1. the method for a silica gel push-button surface broken colour radium carving is accomplished 2 kinds of colors that radium carver preface can embody printing ink A, B later in same zone, it is characterized in that: adopt following steps to make:
