Abstract

The invention discloses a preparation method of wear-resistant ink for silicone rubber keys, and relates to a preparation method of ink, which comprises the following steps: (1) preparation of reinforced resin, (2) preparation of a wear-resistant modified filler, (3) weighing of raw materials, and (4) preparation of finished ink. The method is reasonable in overall process matching, relatively simple in steps and easy to apply and popularize, the prepared ink has very high wear resistance, corrosion resistance, stability and the like, and the service life is effectively prolonged.

Description

technical field [0001] The present invention relates to a kind of preparation method of ink, more specifically, it relates to a kind of preparation method of wear-resistant ink for silicone rubber key. Background technique [0002] With the rapid popularization of electronic products such as computers and mobile phones in the world, button products have formed a large-scale industry. In electronic and electrical products, silicone rubber keys based on high-temperature vulcanized silicone rubber account for more than 75% of various keys. Keys, as the main components of computers, calculators and mobile phone keyboards, are often exposed to the beating and friction of fingers for a long time. Therefore, there are extremely high requirements for the abrasion resistance and hand sweat resistance of the characters and patterns marked on it. Because the wear resistance of general ink is very poor, the characters are easy to wear and fall off, so it is necessary to spray the char...
