Title:
POLYVINYL CHLORIDE POLYMER HEAT STABILIZER, PREPARATION METHOD THEREFOR AND USE THEREOF, COMPOSITE STABILIZER, AND METHOD FOR PREPARING POLYVINYL CHLORIDE SHEET
Document Type and Number:
WIPO Patent Application WO/2023/116870
Kind Code:
A1
Abstract:
The present invention discloses the preparation of an ultrasonic radiation calcium/lanthanum-based polyvinyl chloride polymer heat stabilizer and the use thereof in a soft product, wherein the ultrasonic radiation calcium/lanthanum-based polyvinyl chloride polymer heat stabilizer takes calcium/lanthanum-based metal oxide as a component to be activated, and is enhanced after ultrasonic radiation by blending modification and bonding with PVC, such that the ultrasonic radiation calcium/lanthanum-based polyvinyl chloride polymer heat stabilizer is prepared; the calcium/lanthanum-based metal oxide is one or more of calcium oxide and lanthanum oxide. The ultrasonic radiation calcium/lanthanum-based polyvinyl chloride polymer heat stabilizer of the present invention can improve both the heat stability of the polymer and the compatibility of the blend with the PVC system; and the polymer heat stabilizer and a product thereof prepared by the present patent are simple in process, low in cost, non-toxic and harmless, and have potential economic and environmental benefits.
