For PVC heat stabilizer and its synthetic method (by machine translation)
The present invention provides a novel metal-soap heat stabilizer, the structure comprises a maleimide group, substituted amide group, […] group and metal ion, can be used as the heat stabilizer PVC processing process. Compared with the existing heat stabilizer, its advantage lies in a plurality of functional groups in the synthesis of the same molecule, can better coordination function; in the molecule there is a plurality of ether groups and amide, complex processing can be rapidly produced in the process of a Lewis acid such as zinc chloride, significantly reduce the products in the processing of the zinc burning phenomenon, and has better long-term thermal stability. The compounds of novel structure, the synthetic process route is comparatively simple, rich source of raw materials, product is non-toxic, environmental protection, with the traditional calcium-zinc stabilizer control, has more excellent initial and long-term thermal stability, and there is little consumption, good compatibility with the polymer, can be used as a traditional calcium zinc heat stabilizer upgrading products. Its zinc, lime soap can be used as the main stabilizer, the stabilizer in the addition amount is 1 – 40%. (by machine translation)
