▎ 摘　　要

NOVELTY - A liquid calcium-zinc graphene PVC phenol-free heat stabilizer comprises 25-45 pts. wt. calcium oxide, 25-45 pts. wt. zinc oxide, 3-8 pts. wt. basic aluminum sodium carbonate, 5.5-10 pts. wt. beta -diketone, 10-30 pts. wt. oleic acid, 20-40 pts. wt. octanoic acid, 30-60 pts. wt. castor oil, 0.05-1 pts. wt. graphite, and 0.1-0.3 pts. wt. phenol-free antioxidant. The phenol-free antioxidant is ketone, benzene phthalocyanine or N, N-dibenzyl hydroxylamine. USE - Liquid calcium-zinc graphene PVC phenol-free heat stabilizer. ADVANTAGE - The heat stabilizer is heat-resistant, and has heat-conducting property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of liquid calcium-zinc graphene PVC phenol-free heat stabilizer comprising mixing oleic acid, octanoic acid, castor oil, stirring uniformly at constant temperature at 90-110 degrees C, holding for 2-3 hours, adding calcium oxide and zinc oxide, further stirring and heating at 120-140 degrees C, adding basic aluminum sodium carbonate, beta -diketone, graphite, and phenol-free antioxidant, and stirring uniformly to obtain the product.
