Problems solved by technology

[0004] However, the commonly used surfactant additives have high hydrophilicity and low molecular weight. According to the national standard for the ultraviolet absorption test of the blood transfusion (liquid) equipment extract, the results are often high, which affects product quality; and silicone oils The refractive index of the substance is quite different from that of PVC, and the opacity of the product will be seriously affected after adding

Abstract

The invention discloses a Ca-Mg-Zn liquid stabilizer and an application thereof. At present, a common PVC material has the problems of white frost generation in water mist and bag body adhesion afterhigh temperature and pressure steam disinfection. The Ca-Mg-Zn liquid stabilizer includes: zinc organic acid salt, calcium oleate, magnesium organic acid salt, a blocked polyethylene oxide-polypropylene oxide ricinoleate being 2400-2600 in molecular weight, and a solvent; wherein EO / PO molar ratio of the blocked polyethylene oxide-polypropylene oxide ricinoleate is 1:3-4. The components have excellent synergistic effect, so that the stabilizer is good in compatibility with polyvinyl chloride resin and is toxic-free and environment-friendly. The stabilizer has excellent transparency, can resisthigh temperature adhesion and prevent white frost generation in water mist, and has outstanding solution effect for problems in (blood) transfusion devices in practical application at present.

Description

technical field [0001] The invention relates to a polyvinyl chloride heat stabilizer, in particular to a calcium-magnesium-zinc liquid stabilizer and its application. Background technique [0002] In the field of medical blood transfusion (liquid) apparatus, the application of polyvinyl chloride resin (PVC) is very important. Usually use soft PVC material calendering to make medical blood transfusion (liquid) container film, then make bag through high-frequency heat sealing, combine PVC catheter and other auxiliary parts to form a complete set of blood (liquid) equipment. During this process, due to the easily degradable characteristics of polyvinyl chloride, once it degrades, it cannot pass the strict standard of the national standard GB15593 for medical blood transfusion (liquid) appliances. Therefore, such stabilizers must have efficient thermal stability properties. [0003] Since blood transfusion (liquid) equipment needs specific monitoring when used, good transparen...
