[0046] The preparation method of modified nano-titanium dioxide is:

[0047] 1) The nano-titanium dioxide is prepared into a dispersion liquid with a mass concentration of 10-15% with absolute ethanol, and the ultrasonic dispersion is uniform, and the pH is adjusted to 3.0-4;

[0048] 2) In the reaction kettle, add the emulsion obtained in step 1), then add a fluorine-containing silane coupling agent with a mass of 0.5-2% of nano-titanium dioxide, heat to 50-70° C., and stir and react at a constant temperature for 6 hours;

[0049] 3) Slowly stir the product obtained in step 2), add 7%-13% of the total mass of fluorosilicone adhesive, and continue to stir for 2 hours until uniformly mixed, which is the modified nano-titanium dioxide.

[0050] The fluorine-containing silane coupling agent described in the preparation method of the modified nano-titanium dioxide is trifluoropropyltrimethylsilane. Fluorosilicone adhesive is produced by Shenzhen Guanheng New Material Technology C...

Abstract

The invention relates to highlight printing ink. The highlight printing ink includes, by mass, fluorine-modified polyurethane resin, a levelling agent, an oxidant, aluminum powder, an adhesion promoter, pigment, a defoamer, a dispersing agent, polyacrylate resin, modified nanometer titanium dioxide and a solvent. The highlight printing ink is good in adhesion force to polycarbonate automotive meter panel substrates, high in light reflection rate, waterproof, antifouling, and capable of effectively preventing crusting and granulation phenomena. The automotive meter panel substrates are provided with highlight and matt printing ink layers through screen printing, and the highlight printing ink and the matt printing ink are different in light reflection intensity, thus forming a visual sense difference and achieving a metal wire drawing effect.

Description

technical field [0001] The invention relates to a high-gloss ink, which belongs to the field of inks. Background technique [0002] The metal wire drawing effect is widely used. The traditional circular wire drawing process mainly includes mold treatment and polishing process, but there are many production links, low production efficiency, not environmentally friendly, and poor product stability. The high-gloss and matt ink layers are set on the substrate of the automobile dashboard through screen printing. The high-gloss and matt inks have strong or weak reflections on light, resulting in visual difference, and then achieve the effect of metal wire drawing. However, the existing high-gloss ink has poor adhesion to the instrument panel and low brightness, which cannot meet the printing requirements of the automotive instrument panel. Contents of the invention [0003] The purpose of the present invention is to provide a high-gloss ink, which improves the adhesion and brig...
