[0018] A method for preparing high-reflectivity ink, the white ink comprises: 25%-45% resin, 20%-35% toner, 8%-20% additive, 10%-28% Solvent, 5%-10% curing agent, 2%-15% thinner, 2%-12% varnish, 2%-15% diffusion particles.
[0019] The reflective ink reflectance of the white ink formed by mixing the above ingredients is greater than or equal to 85%. It has a light diffusion effect while having a reflective effect. , Rely on solvent wiping properties, Rely on high temperature within 300°.
[0020] Traditional inks are not reflective or reflective, and some inks are also light-absorbing. Therefore, this application adopts the white ink of the above formula and coats it on the glass backplane of the ultra-thin display module for use in It is used as a reflective sheet as a light guide plate to reflect light.
[0021] The diameter of the diffusion particle is 3um-30um, the resin is epoxy resin, the toner is titanium dioxide or lithopone or zinc oxide, the auxiliary agent is isop...
Embodiment 1
[0026] Selection: 25% epoxy resin, 20% titanium dioxide, 8% isophorone, 10% ethanol, 10% H01 curing agent, 15% 783 thinner, 5% rosin resin, 7% diffusion particles;
[0027] Mix and stir epoxy resin, titanium dioxide, isophorone, ethanol, 783 thinner, rosin resin, and diffusion particles evenly, then add H01 curing agent to the mixed material after stirring evenly, stir evenly again, and let it stand for 10 minutes above;
[0028] Prepare a glass backplane 31 that has been cut, edged, and tempered, and then perform cleaning; place the cleaned glass backplane 31 on an adsorption platform, and print with white ink. Dry (150°C × 30 minutes), and finally inspect to obtain an ink layer with a reflectivity ≥ 85%, with uniform printing thickness, and no bubbles, perforations and other defects.

[0030] Selection: 30% epoxy resin, 35% titanium dioxide, 10% isophorone, 14% ethanol, 5% H01 curing agent, 2% 783 thinner, 2% rosin resin, 2% diffusion particles;
[0031] Mix and stir epoxy resin, titanium dioxide, isophorone, ethanol, 783 thinner, rosin resin, and diffusion particles evenly, then add H01 curing agent to the mixed material after stirring evenly, stir evenly again, and let it stand for 10 minutes above;
[0032] Prepare a glass backplane 31 that has been cut, edged, and tempered, and then perform cleaning; place the cleaned glass backplane 31 on an adsorption platform, and print with white ink. Dry (150°C × 30 minutes), and finally inspect to obtain an ink layer with a reflectivity ≥ 85%, with uniform printing thickness, and no bubbles, perforations and other defects.
