Comparison of stability and weatherability of PVC thermal stabilizer.
PVC heat stabilizer is to prevent the action of the molecular chain of PVC resin under the action of heat and shearing caused destruction and degradation, but also prevent the storage and use process caused by light of oxygen and under the action of heat oxygen degradation. At present, PVC thermal stabilizer mainly includes compound lead salt stabilizer, organic tin stabilizer and various environmental stabilizers (PVC calcium and zinc heat stabilizer).
Composite lead salt stabilizer has good thermal stability, but in the process of machining will remain free of S042 -, Cl - ions, if these ions content is too high, under the direct effect of visible light, with Pb2 +, to generate on the surface of gray spots, sometimes mixed with yellow, gray and residues in products of Pb2 + easy to react with the S2 - in the air, produce black PbS, thus easy to black on the surface of the products.
Organotin heat stabilizer has good heat stability and transparency, but the light transmittance of organic tin and PVC close, can not effectively protect the damaging effects of ultraviolet on PVC molecular so weather resistance than lead salt and all kinds of environmental protection (calcium zinc) heat stabilizer is poor, only with a large number of shielding effect of titanium dioxide can meet the requirements of weather resistance.
All kinds of environmental stabilizers (PVC calcium and zinc heat stabilizer) are mainly composed of calcium and zinc soap salts, auxiliary heat stabilizers, antioxidants and lubricants; Stabilising at the same time, it can absorb ultraviolet light, all kinds of environmental protection (calcium zinc) heat stabilizer in lots of different kinds of antioxidants.
