▎ 摘　　要

NOVELTY - Stone plastic composite floor comprises a stone plastic composite floor main body comprising a stone plastic composite base material layer. The stone plastic composite base material layer comprises 80-120 pts. wt. polyvinyl chloride resin, 200-300 pts. wt. heavy molecular weight calcium carbonate powder, 20-40 pts. wt. nano-calcium carbonate, 0.5-2 pts. wt. lubricant, 5-10 pts. wt. calcium-zinc stabilizer, 1-5 pts. wt. microcrystalline cellulose, 10-15 pts. wt. ultra-dispersant, 1-3 pts. wt. tourmaline powder, 1-10 pts. wt. carbon nanotube and 1-8 pts. wt. bacteriostatic agent. USE - Used as stone plastic composite floor. ADVANTAGE - The floor has good tensile strength and stability, environmental protection, antibacterial and antistatic performance, and lower dimensional deformation rate and stable performance.
