NOVELTY - A masterbatch comprises 100-120 pts. wt. polypropylene resin as carrier resin, 30-45 pts. wt. alicyclic epoxy resin, 1-4 pts. wt. crosslinking agent, 6-8 pts. wt. nano alumina powder, 10-15 pts. wt. nano ceramic powder, 8-12 pts. wt. glass fiber, 2-5 pts. wt. nano graphene, 8-15 pts. wt. nano wood powder, 0.8-1.1 pt. wt. coupling agent, and 0.6-1 pt. wt. dispersant. USE - Masterbatch is used for reinforcing polypropylene. ADVANTAGE - The masterbatch increases the crosslinking density of polypropylene, and improves tensile strength. Glass fiber and nano graphene improve the mechanical property of polypropylene resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of masterbatch.
