▎ 摘　　要

NOVELTY - Nano-type anti-blue light masterbatch comprises 80-100 pts. wt. polyolefin resin, 6-10 pts. wt. alumina, 4-6 pts. wt. silica, 5-9 pts. wt. silicon carbide, 2-4 pts. wt. graphene, 5-15 pts. wt. pigment, 4-8 pts. wt. blue light absorber, 1-2 pts. wt. coupling agent, 3-6 pts. wt. plasticizer, 1-2 pts. wt. lubricant, 1-3 pts. wt. antioxidant, 1-3 pts. wt. dispersant. USE - Nano-type anti-blue light masterbatch. ADVANTAGE - The nano-type anti-blue light masterbatch has anti-blue light performance improved by 6-7% compared with the traditional masterbatch, and the service life is greatly extended in the place where blue light interferes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nano-type anti-blue light masterbatch, which involves mixing raw materials according to the ratio, adding raw materials to the mixer for high-speed stirring for 30 minutes, discharging materials, and then adding to the screw extruder for extrusion and granulation.
