PVC PVC Hybrid type PVC stabilizer comprising liquid and powder

摘要

The present invention includes 50 to 150 parts by weight of a Ca/Zn liquid stabilizer, 50 to 150 parts by weight of a Ca/Zn powder stabilizer, and 2 to 30 parts by weight of a silicon compound, but the ratio of 0.5 to 90 parts by weight based on 100 parts by weight of the polyvinyl chloride resin It relates to a composite stabilizer for PVC, characterized in that mixed with. The composite stabilizer for PVC according to the present invention includes both a Ca/Zn liquid stabilizer and a Ca/Zn powder stabilizer to complement each other's disadvantages of a liquid stabilizer or a powder stabilizer, and use a Ca/Zn liquid stabilizer or a Ca/Zn powder stabilizer. Compared to the case of each use, it is possible to manufacture PVC products with improved thermal stability and weather resistance.
