▎ 摘 要
NOVELTY - A flame-retardant cable comprises a cable component and flame-retardant layer comprising 45-52 pts. wt. PVC plastic, 0.1-1 pt. wt. graphene, 3-7 pts. wt. vinyl acetate, 0.5-3 pts. wt. nano-hydroxyapatite, 19-23 pts. wt. light calcium carbonate, 11-13 pts. wt. triple superphosphate, 2.5-3.5 pts. wt. stabilizer, 0.1-0.3 pt. wt. polyethylene wax, 0.14-0.17 pt. wt. stearic acid, 5 pts. wt. flame-retardant additive, 34-37 pts. wt. dioctyl terephthalate, 0.2-1.5 pts. wt. rare earth nitrate and 0.1-1 pt. wt. titanate coupling agent. USE - Flame-retardant cable (claimed). ADVANTAGE - The cable has improved flame retardance.
