Abstract
A supported PVC (polyvinyl chloride) heat stabilizer is characterized in that the stabilizer takes activated clay as a supporter, an active component, namely, calcium hydroxide, is supported in the supporter, the surface is modified by fatty acid which is good in affinity with PVC, and a specific implementation method is as follows: the activated clay is stirred to be dispersed in water, then a calcium hydroxide emulsion is added for supporting, the fatty acid is added for modifying after supporting, and finally, the PVC heat stabilizer is obtained after filtration, drying and crushing. The stabilizer cannot release salt or organic matters to pollute the PVC after adsorbing hydrogenchloride and is non-toxic, odorless, safe, environment-friendly and easy to prepare, and raw materials are easy to obtain.
