Problems solved by technology

Although the shading inks currently on the market can meet the basic requirements of use, their surface-drying temperature in 1 minute must reach 135 degrees or more, resulting in a large waste of electric energy, and low hardness after curing. The highest hardness can only reach 2H, and the shading effect It is not ideal, and it is particularly necessary to re-develop a new shading ink with good comprehensive performance

Embodiment 1

[0042] First prepare the carrier:

[0043] Vinyl resin 9%

[0044] Saturated resin 60%

[0045] Polyurethane 11%

[0046] Cellulose acetate butyrate 2%

[0047] Trimeric isocyanate 3%

[0048] Butyl tin oxide derivative 0.3%

[0049] Low molecular weight polyolefin 0.2%

[0050] Organic bentonite 0.5%

[0051] Matting Powder 1%

[0052] Dimethyl nylon acid ester (DBE) 13%

[0053] Weigh the raw materials used to prepare the carrier according to the above ratio, put the vinyl acetate resin, saturated resin, polyurethane and dimethyl nylon acid (DBE) in the electric heating reaction pot first, and stir thoroughly to make the vinyl acetate resin, saturated resin 1. Polyurethane is completely dissolved in dimethyl nylon acid (DBE), and 500 kg of the above raw materials are stirred for 5 to 8 hours. After the stirring is complete, add cellulose acetate butyrate, trimer isocyanate, butyl tin oxide derivatives, low-molecular polyolefin, organic benton...

Abstract

The invention discloses a low-temperature thermosetting light-tight ink and a preparation method thereof. The light-tight ink is prepared by blending new carries and taking the carriers as raw materials and then re-adjusting the proportions of talc powder, barium sulfate, titanium white, insulating carbon black and the carriers; the obtained light-tight ink, compared with the present existing similar products, is greatly reduced in surface dry temperature and thereby greatly saves electric energy; the hardness of the solidified light-tight ink is capable of reaching up to 3H, and the light-tight performance thereof is greatly improved; the light-tight ink is applied to the insulation protection of products such as a photoelectric touch module, a touch screen, an electronic housing and the like; and compared with the present existing similar products, the usability of the light-tight ink is greatly improved.

Description

[0001] technical field [0002] The invention relates to a low-temperature thermosetting light-shielding ink and a preparation method thereof. [0003] Background technique [0004] Light-shielding ink is mainly based on the powdery particles of insulator materials that are evenly distributed on the printing surface. It is widely used in the insulation protection of photoelectric touch modules, touch screens and electronic casings, so that the products have electromagnetic shielding functions. Its appearance is beautified. Although the shading inks currently on the market can meet the basic requirements of use, the surface-drying temperature in 1 minute must reach more than 135 degrees, and the waste of electric energy is large. The hardness after curing is low, and the hardness can only reach 2H at the highest. The shading effect It is not ideal enough, and it is particularly necessary to redevelop a new shading ink with good comprehensive performance. [0005] Conten...
