Preparation method of modified resin printing ink coating

Abstract

The invention discloses a preparation method of a modified resin printing ink coating. The preparation method comprises the following procedures: 1) grinding and dispersing polyester modified methylphenyl silicone resin, titanium dioxide and the like to obtain a primary product; 2) adding a dispersing agent and the like into the primary product, and grinding and dispersing to obtain a secondary product; 3) adding polyether modified siloxane and the like into the secondary product and stirring to obtain a printing ink main agent; 4) adding a curing agent into the printing ink main agent, and grinding, dispersing and filtering to obtain an optimized main agent; 5) adding xylene and cyclohexanone into the optimized main agent, and stirring to obtain modified resin printing ink; 6) performing cleaning and drying treatment on a glass slide; and 7) putting a proper amount of modified resin printing in on a silk screen board, performing silk-screen printing by taking the glass slide as a printing substrate, and solidifying and cooling the glass slide subjected to silk-screen printing to obtain the modified resin printing ink coating. By adoption of the printing ink coating prepared by the method, tests of the high-temperature resistance, the printability and the paint film property of the modified resin printing ink can be facilitated.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a preparation method of a modified resin ink coating. Background technique [0002] The intelligentization of electronic products is the development trend of the times. With the wide application of touch screens in smart phones, tablet computers and other fields, the touch screen industry has developed rapidly. The integrated capacitive touch screen (OGS) can meet the ultra-thin requirements of intelligent terminals of electronic products to the greatest extent, and is an inevitable choice for high-end brand terminals with touch screens in the future. The OGS touch screen is coated with ITO conductive film on the ink film layer. Since the ITO coating process needs to be completed at a high temperature of 280 ° C ~ 300 ° C, the touch screen ink must have excellent high temperature resistance. [0003] High temperature resistant touch screen ink is mainly composed of linking material...

Problems solved by technology

However, the existing high-temperature-resistant inks based on inorganic glass are difficult to maintain high-temperature thermal stability, while having good physical and mechanical properties and chemical reagent corrosion resistance.

For example, some high-temperature resistant inks have good heat resistance and adhesion, but their silk screen printing process costs are high, which is not conducive to wide application in industry; some high-temperature resistant inks have good chemical corrosion resistance , adhesion and hardness, but its heat-resistant temperature is limited, and it is difficult to withstand baking at 200°C
