Abstract

The invention relates to a ternary complex heat stabilizer of tombarthite-stearic acid-8-hydroxyquinoline and preparation method for the heat stabilizer. The heat stabilizer is a ternary tombarthite complex prepared with three components of tombarthite salt, stearic acid and 8-hydroxyquinoline; the chemical molecular formula is Re(C18H35O2)x.(C9H7NO)y, wherein the Re is tombarthite element; the C18H35O2 is stearate radical; the C9H7NO is the 8-hydroxyquinoline; x:y is equal to 1:2 or 2:1. The heat stabilizer and the preparation method have the advantages that the preparation method comprehensively utilizes heat stabilization and antimicrobial action of the stearic acid, the tombarthite and the 8-hydroxyquinoline, and achieves dual effect; the heat stabilizer is low in toxicity, good in plasticization and low in preparation cost.

Description

technical field [0001] The invention relates to a rare earth-stearic acid-8-hydroxyquinoline ternary complex heat stabilizer and a preparation method thereof, in particular to a PVC material heat stabilizer and a preparation method thereof, and belongs to the technical field of polymer materials. Background technique [0002] During the processing and use of PVC, due to the degradation of light, heat and other factors, HCl is released. If it is not removed in time, HCl will accelerate the degradation of PVC. Rare earth stearate is often used as a heat stabilizer for PVC, mainly because rare earth ions have 4f5d empty electron orbitals, which can adsorb HCl molecules to form complexes with unequal ionic bonds and bond energies, and can also adsorb active Cl on PVC. - , effectively prevent the catalytic HCl removal reaction, prevent the generation of conjugated double bonds, increase the thermal stability of PVC, and at the same time make the components in the material system ...
