In order to solve the problems, the most common method at present is to compound alkali metal single components such as calcium, zinc, magnesium and the like and tris (epoxypropyl) isocyanurate by using a micro-emulsification technology, and the compound heat stabilizer obtained by compounding has the advantages of long shelf life, good lubricity, capability of improving the transparency of polyvinyl chloride and improving the initial coloration of the polyvinyl chloride, but the compound heat stabilizer obtained by micro-emulsification can influence the low-temperature resistance of the polyvinyl chloride to be poor.
