Embodiment 1
[0030] A preparation method of an energy-saving LED lamp shade material, comprising the steps of:
[0031] Step S1 is based on the preparation of carbonate polycondensation monomers: under a nitrogen atmosphere, dissolve 3.1kg of 2,3-diphenol butadiene and 1kg of vinylene carbonate in 12kg of tetrahydrofuran to form a solution, and then add the solution to a reflux In a three-neck flask with a condenser tube and an electric stirrer, reflux and stir the reaction at 100°C for 8 hours, and then spin evaporate to remove the solvent to obtain a polycondensation monomer based on carbonate;
[0032] Preparation of polycondensate in step S2: 1.14 kg of polycondensation monomer based on carbonate, (Z)-3-(3-chloro-2-fluorophenyl)-2-(4-chloro-2- Add 1kg of fluorophenyl)-2-acrylonitrile, 0.3kg of sodium hydroxide, and 0.3kg of chlorobenzoquinone to a three-necked flask connected with a water separator, add 8kg of dimethyl sulfoxide and 3kg of toluene, and heat the reaction system to 95°C...
Embodiment 2
[0037] A preparation method of an energy-saving LED lamp shade material, comprising the steps of:
[0038] Step S1 is based on the preparation of carbonate polycondensation monomers: under a helium atmosphere, 3.1 kg of 2,3-diphenol butadiene and 1 kg of vinylene carbonate are dissolved in 12.5 kg of acetone to form a solution, and then the solution is added to the container In a three-necked flask with a reflux condenser and an electric stirrer, reflux and stir the reaction at 102°C for 8.5 hours, and then spin evaporate to remove the solvent to obtain a polycondensation monomer based on carbonate;
