Problems solved by technology

However, methyl tin mercaptide is expensive and has peculiar smell. Therefore, it is urgent to reduce the amount of use and use cost, and to find synergistic effects and environmental degradation. Therefore, research on auxiliary stabilizers such as commercially available calcium zinc, polyols, nano-titanium dioxide and titanic acid Butyl ester, it is of great significance to explore its possible synergistic effect and environmental friendliness

Embodiment 1

[0018] 0.5 parts of PVC resin, DOTP50, 0.5 thiolmetin, 0.5 parts of commercially available calcium zinc, 1.0 parts of bispurate glycol, 0.5 butyl titanate, and mixed thiol methyl tin liquid and DOTP liquid mix well. The commercially available calcium zinc, double-ravaniol, butyl butyl butyl butyl butyl is mixed, and stirred thoroughly to mix evenly. The completely dissolved stabilizer solution was slowly added to the PVC resin, stirred, mixed, mixed with powder to add a high-speed butt, controlled the admission temperature of 170-180 ° C, but refining 2 to 3 min Then, the plate is then plated with a flat plate, that is, the sample sheet is made.

Embodiment 2

[0020] 0.5 parts of PVC resin, DOTP50, thiolmetin methyl tin, 0.5 coppeucetal zinc, 1.0 parts of bispurate glycol, 1.0 but ester butyl butyl, mixed thiol methyl tin liquid and DOTP liquid mix well, The commercially available calcium zinc, double-ravaniol, butyl butyl butyl butyl butyl is mixed, and stirred thoroughly to mix evenly. The completely dissolved stabilizer solution was slowly added to the PVC resin, stirred, mixed, mixed with powder to add a high-speed butt, controlled the admission temperature of 170-180 ° C, but refining 2 to 3 min Then, the plate is then plated with a flat plate, that is, the sample sheet is made.

Embodiment 3

Abstract

The invention discloses a composite thermal stabilizer containing organic tin, calcium zinc and titanium and its application, wherein the composite thermal stabilizer is composed of a main stabilizer and an auxiliary stabilizer, wherein the main stabilizer is selected from mercaptan Methyl tin, octyl tin mercaptide, butyl tin mercaptide or dioctyl tin laurate, auxiliary stabilizers are commercially available calcium zinc, dipentaerythritol, butyl titanate and nano titanium dioxide. The present invention utilizes the synergistic stabilizing effect between methyltin mercaptide, commercially available calcium zinc, dipentaerythritol, butyl titanate and nano-titanium dioxide to reduce the amount of methyltin mercaptide used, and the effect is better than that of using methyltin mercaptide alone. The tin-based stabilizer effectively improves the stability of PVC and has potential environmental photodegradability.

Description

Technical field [0001] The present invention relates to a polymer material processing aid, specifically a composite heat stabilizer containing tin, calcium zinc and titanium, and its application thereof. Background technique [0002] Polyvinyl chloride and its products are an important polymer material in my country than 18 million tons. Because the carbon chlorine bond can be 243kJ / mol, it is often necessary to add thermal stabilizers, mainly composite lead salts, liquid metal soap ( BA / CD, Ba / Cd / Zn, Ba / Zn), composite calcium, composite organic tin, rare earth and organic stabilizer. Among them, the lead salts have been tended to be eliminated due to poisoning, and is currently moving towards non-toxic, efficient, multi-function, cost-effective and degradable direction. The organic tin stabilizer is about 1 / 4 in the processing of polyvinyl chloride products, and has high efficiency, excellent thermal stability, transparency, shallow, better than other PVC thermostats, ...
