Mini LED screen packaging adhesive film, preparation method and packaging method

According to the Mini LED screen packaging adhesive film, the preparation method and the packaging method provided by the invention, the Mini LED screen packaging adhesive film comprises epoxy resin, UV resin, silica powder, a reactive diluent, solvent-free carbon black color paste and fumed silica, a light-heat dual-solid system with good compatibility is adopted, and different macromolecular chains are subjected to segmented curing, crosslinking and winding under the light-heat dual-solid system; the flexible UV component and the rigid epoxy component are matched to facilitate release of curing internal stress, so that the curing warping degree is reduced, fused silica powder with different particle sizes and refractive indexes is used for compounding, the warping rate, the light transmittance, the haze and the thermal conductivity are optimized through the dense degree of powder stacking, and the curing effect is improved. According to the preparation method, the semi-cured film is prepared ...
