| titleOfInvention | A kind of high polymer heat-resistant polyvinyl chloride based on multielement rare earth heat stabilizer |
| abstract | The present invention provides a kind of high polymer heat-resistant polyvinyl chloride based on multielement rare earth heat stabilizer, the polyvinyl chloride includes High molecular weight polyethylene, trioctyl trimellitate (TOTM), liquid barium zinc, multielement rare earth heat stabilizer and low-molecular polyethylene wax, and the preparation method of wherein multielement rare earth heat stabilizer is：In an inert atmosphere, palladium bichloride and triphenyl phosphorus are added in n-hexane, stirred, add 4 brom-acetophenones, be then added dropwise after triphenyl lanthanum solution, completion of dropping and continue to react, separating-purifying obtains multielement rare earth lanthanum palladium metal compound；It will be stirred in multielement rare earth lanthanum palladium metal compound addition nitric acid, and after being mixed rapidly with malic acid and salicylic alcohol mixed solution, sodium hydrate aqueous solution be added dropwise, heating response will be filtered by vacuum, washs and dried, obtains multielement rare earth heat stabilizer.The degree of polymerization of polyvinyl chloride prepared by the present invention is high, has good synergy between each component, is remarkably improved the heat resistance of pvc material, mechanical property and the performance such as corrosion-resistant. |
