NOVELTY - Material comprises 33-40 pts. wt. linear low-density polyethylene, 15-22 pts. wt. polyamide elastomer, 7-10 pts. wt. zinc oxide, 22-28 pts. wt. glass fiber, 10-16 pts. wt. polyester fiber, 20-26 pts. wt. graphene oxide solution, 12-18 pts. wt. microencapsulated red phosphorus, 15-20 pts. wt. PET resin, 9-17 pts. wt. epoxy resin, 11-18 pts. wt. potassium titanate whisker, 5-11 pts. wt. coupling agent, 6-12 pts. wt. vulcanizing agent, 7-12 pts. wt. flame retardant and 10-15 pts. wt. heat stabilizer. USE - Material for the battery box of an electric forklift. ADVANTAGE - The material has a stable structure, good physical and mechanical properties, high strength and impact resistance, and high precision, small molding shrinkage, has good sealing performance, is easy to install, and is relatively light, improves the endurance of electric vehicles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing battery box material of electric forklift, which involves immersing glass fiber and polyester fiber in a nitric acid solution by ultrasonic treatment for 30-50 minutes, taking out the glass fiber and drying and repeating to obtain mixed fiber, immersing the mixed fiber in graphene oxide solution with a concentration of 0.3-1.2mg/mL, heating to 45-50 degrees C and soaking for 1 hour, and then drying in a vacuum drying chamber for 5-7 hours to obtain composite fiber, using three-dimensionally weave the composite fiber to form a three-dimensional fabric skeleton, mixing polyamide elastomer, zinc oxide,vulcanizing agent, and coupling agent in ratio of 5:0.5:0.3:0.2 at 110 degrees C and discharging material uniformly, mixing linear low-density polyethylene with the mixture, irradiating with gamma rays at a temperature of (-)8-1 degrees C and a humidity of 66-75% for 6-8s, and then mixing microencapsulated red phosphorus, PET resin, epoxy resin, potassium titanate whisker, flame retardant, heat stabilizer with a high-speed mixer, putting into the hopper of the twin-screw extruder and extruding and pelletizing at 175-210 degrees C to obtain composite materials, and putting the three-dimensional fabric skeleton into a mold, adding the composite material and injection molding.
