NOVELTY - Polyethylene tape comprises 25-40 pts. wt. polyethylene, 2-10 pts. wt. nylon 1010, 1-6 pts. wt. epoxy resin, 0.2-1 pts. wt. vinyl trichlorosilane, 0.2-0.8 pts. wt. polyethylene-grafted maleic anhydride, 2-10 pts. wt. modified composite fiber, 1-3 pts. wt. carbon nanotube, 1-3 pts. wt. graphene, 1-3 pts. wt. kaolin, 1-3 pts. wt. glass fiber, 1-3 pts. wt. nano-silica, 0.2-0.6 pts. wt. antioxidant, 0.2-0.6 pts. wt. ultraviolet light absorbing agent, and 0.2-0.6 pts. wt. antioxidant. USE - Polyethylene tape. ADVANTAGE - The polyethylene tape has good mechanical property, is light weight, and has aging resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing modified composite fiber, which involves: (A) mixing 40-80 pts. wt. wollastonite and 20-50 pts. wt. mica powder, heating at a temperature of 300-500 degrees C for 1-2 hours, and grinding to a grain diameter of 20-60 mu m; (B) soaking the grounded material in sulfuric acid solution for 30-60 minutes, filtering, washing with water, and drying; (C) adding 40-60 pts. wt. water to the dried product, mixing uniformly with 0.5-1.5 pts. wt. titanic acid ester and 40-60 pts. wt. pea protein, and treating at a temperature of 75-85 degrees C; (D) adding 20-40 pts. wt. jute fiber and 30-60 pts. wt. silk fiber, mixing uniformly, adding 1-3 pts. wt. hydroxybutyrate pentanoic acid co-polyester, 1-3 pts. wt. poly-beta-hydroxybutyric acid, stirring uniformly, and heating to a temperature of 165-175 degrees C along with stirring for 20-50 minutes; and (E) subjecting the obtained product to ultrasonic reaction at an ultrasonic power of 400-600 watt for a time period of 30-50 minutes, filtering, feeding into an oven for 2-4 hours at a temperature of 110-125 degrees C, cooling, and powdering to obtain the modified composite fiber.
