Abstract

The invention relates to application of diquinoline phosphate in a PVC barium-zinc composite heat stabilizer, the structural formula of the diquinoline phosphate is shown in the specification, the diquinoline phosphate compound adopts a novel heterocyclic group to replace an aliphatic aromatic group, and the compound is added in the preparation of a liquid barium-zinc stabilizer, so that the precipitation resistance of the liquid barium-zinc stabilizer can be effectively improved, efficient heat aging resistance (static stability) is also achieved, and excellent processability in secondary printing of advertising films and the like can be realized.

Description

technical field [0001] The invention relates to the application of bisquinoline phosphite in a PVC barium-zinc composite heat stabilizer. Background technique [0002] Due to the poor compatibility of metal soap and PVC resin in traditional barium-zinc PVC composite heat stabilizers, metal soap is continuously precipitated during the process of PVC calendering, and the precipitate is attached to the surface of the PVC film, which affects the printing, inkjet and printing of the product. transparency. Therefore, it is necessary to add an anti-separation agent to the liquid stabilizer to improve the inkjet performance of the PVC film and inhibit the precipitation. At present, most of the anti-separation agents with better effects in liquid stabilizers contain phenolic substances, and their dosage is 4-10% (accounting for the percentage of liquid stabilizers). It is suitable for soft PVC films with low environmental protection requirements. However, most toy films exported to...
