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

Embodiment 1

[0025] A preparation method of modified resin ink coating, comprising the following steps:

[0026] 1) Take an appropriate amount of polyester-modified methylphenyl silicone resin, titanium dioxide and barium sulfate and add it to a fine grinder, grind and disperse at a speed of 2000~2500r / min for 30 minutes to obtain primary products and set aside;

[0027] 2) Add appropriate amount of dispersant, silane coupling agent, octylphenol polyoxyethylene ether, modified chlorinated polypropylene, polytetrafluoroethylene wax and aminotrimethylphosphoric acid to the primary product obtained in step 1). Grind and disperse for 60 minutes at a speed of 2000~2500r / min to obtain a secondary product for later use;

[0028] 3) Add an appropriate amount of hexamethoxymethylmelamine resin to the secondary product obtained in step 2), grind and disperse for 15 minutes at a speed of 800~1000r / min, filter the material through a 200-mesh filter, and obtain the ink main agent for future use ;

Abstract

The invention discloses a preparation method of a modified resin ink coating. The preparation method comprises the following working procedures: 1) taking an appropriate amount of polyester modified methyl phenyl silicone resin and the like into a refining mill, and carrying out grinding dispersing to obtain a primary product; 2) adding a dispersing agent, a silane coupling agent and the like into the primary product, and carrying out grinding dispersing to obtain a secondary product; 3) adding hexakis(methoxymethyl)melamine into the secondary product, and carrying out grinding dispersing to filter and obtain an ink main agent; 4) adding dimethylbenzene and cyclohexanone into the ink main agent, and stirring to obtain the modified resin ink coating. Ink prepared by adopting the preparation method has good printability and paint film property while high temperature resistance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a preparation method of 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 materials,...
