| titleOfInvention | Lanthanum sorbate composite heat stabilizer for PVC |
| abstract | The invention provides a lanthanum sorbate composite heat stabilizer for PVC, which is prepared by compounding lanthanum sorbate and zinc stearate or lanthanum sorbate and calcium stearate, wherein the molar ratio of lanthanum sorbate to zinc stearate is 3: 1-15: 1, and the molar ratio of lanthanum sorbate to calcium stearate is 1/3: 1-3: 1. In the invention, conjugate double bonds which can be added in a sorbic acid molecular chain and rare earth lanthanum ions act synergistically, and lanthanum sorbate is compounded with zinc stearate or calcium stearate according to a similar compatibility principle. The lanthanum sorbate composite heat stabilizer for PVC has excellent static heat stability and dynamic heat stability. |
