NOVELTY - Floor-specific low-odor phenol-free calcium-zinc stabilizer comprises 20-45 wt.% main stabilizer, 22-32 wt.% plasticizer, 3-8 wt.% antioxidant, 5-10 wt.% hexagonal boron nitride graphene, 4-9 wt.% lubricant and 5-10 wt.% adjuvant. USE - Floor-specific low-odor phenol-free calcium-zinc stabilizer used in ultra-permeable polyvinyl chloride product,. ADVANTAGE - The floor-specific low-odor phenol-free calcium-zinc stabilizer has high specific surface area because of hexagonal boron nitride graphene, and has good thermal stability, processability and flame retardance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing floor-specific low-odor phenol-free calcium-zinc stabilizer, which involves: (A) adding calculated ratio of main stabilizer into a reaction container, and stirring at 60-90 degrees C for 30-60 minutes; (B) adding plasticizer, lubricant, antioxidant and auxiliary agent, and stirring at 70-90 degrees C for 45-60 minutes; and (C) adding hexagonal boron nitride graphene, stirring at 75-95 degrees C for 20-30 minutes, and cooling to obtain desired product.
