[0038]DETAILED DESCRIPTION OF THE SHENCS The preparation method of the thermosetting quantum dot glue of the mixed quantum dot includes the steps of:
[0039]Step 1, mix the diffusion particles and the organic solvent and disperse uniform to obtain dispersion A;
[0040]Step 2, add the quantum point into the dispersion A and disperse uniform to obtain dispersion B;
[0041]Step 3, the amphipressional polymer, the cured delay molecule is added to the dispersion B, and is uniform, and dispersion C is obtained.
[0042]Step 4, adding the polyisocyanate compound to the dispersion C, uniform dispersion, to obtain a thermosetting quantum dot glue having a quantum dot.
[0043]The thermal curing quantum dot glue obtained under this ratio has optimal properties by a large number of experiments.
[0046]Among them, m = 10-30, n = 50-150, r1It is an alkyl chain containing 1 hydroxyl or 1 amine group, and the alkyl chain is preferably ...
