CN110229258A 一种BOPVC薄膜专用PVC树脂及其制备方法与应用 无效 - 驳回

一种BOPVC薄膜专用PVC树脂及其制备方法与应用
摘要：
本发明属于高分子聚合物技术领域，具体涉及一种BOPVC薄膜专用PVC树脂，并进一步公开其制备方法与应用。本发明所述BOPVC薄膜专用PVC树脂，通过将选定表明活性剂改性的聚合度为1500-2000的聚甲基丙烯酸钐制成可稳定存在的分散液，并在PVC树脂聚合终止后，作为功能助剂加入到PVC树脂悬浮体系中进行改性处理，制得的成品PVC树脂具有较高的透明度，较好的流动性、热稳定性，以及优良的抗初级着色性能，可用于制备BOPVC薄膜。该树脂适合于BOPVC薄膜在专用的BOPVC设备上以1.2-1.吨/h的产量连续化工业生产，生产的薄膜厚薄均匀，更适合于大型自动化高速印刷机的多层套印。
摘要（英）：

Belonging to the technical field of macromolecular polymers, the invention in particular relates to a PVC resin special for BOPVC films, and further discloses a preparation method and application thereof. According to the PVC resin special for BOPVC films, a selected surfactant modified samarium polymethacrylate with a polymerization degree of 1500-2000 is prepared into a stable dispersion solution, and at the end of PVC resin polymerization, the dispersion solution is added as a functional additive into the PVC resin suspension system for modification treatment, the prepared finished productPVC resin has high transparency, good fluidity and thermal stability, and excellent primary coloring resistance, and can be used for preparation of BOPVC films. The resin is suitable for continuous industrial production of BOPVC films on special BOPVC equipment with the output of 1.2-1. ton/h, and the produced films are uniform in thickness and are more suitable for multi-layer overprinting of large automatic high-speed printers.
