Embodiment 1
[0026] (1) Production of light conversion masterbatch
[0027] Get 50 parts of low-density polyethylene (PE), 50 parts of plasticizer dimethyl phthalate, light stabilizer take tricresyl phosphate, epoxidized soybean oil, octadecane in a weight ratio of 5: 3: 2 25 parts of zinc-based phosphate complexes, 20 parts of barium stearate and zinc stearate complexes with a weight ratio of 1:1 as heat stabilizer, and sorbitol laurate, hard Fatty acid glyceride complex 15 parts, nano blue light conversion agent ML n @R 1 part, add plastic mixer, control the stirring speed, stir at high speed for 20-30 minutes, control the temperature at 140°C-150°C until the resin is in a plasticized state, discharge it, put it into the granulation extruder to granulate, and set the extrusion The temperature of the machine is 130°C. After the masterbatch is cooled, it is cut and sieved, dried and dried, packed in a moisture-proof packaging bag, and the mouth of the bag is heat-sealed for later use.
