The invention also relates to a preparation method of the calcium-zinc stabilizer.

Description

technical field [0001] The invention belongs to the technical field of stabilizers. More specifically, the invention relates to an environment-friendly calcium-zinc stabilizer for high-stability PVC and a preparation method thereof. Background technique [0002] As we all know, the performance of stabilizers has a great influence on the stability of PVC materials. Commonly used heat stabilizers are mainly lead salt stabilizers, which are cheap and have good heat stabilization effects, but they are highly toxic, seriously endangering human health and polluting the environment. The non-toxic calcium-zinc compound Ca / Zn heat stabilizer is a non-toxic and environment-friendly heat stabilizer recognized by the world, and has the advantages of low price and good lubricity, and has a very broad development space. [0003] However, the PVC stabilizers currently on the market have poor weather resistance, are prone to discoloration, and will significantly reduce the strength of PVC ...
