摘要为解决低温环境表面去污技术难题,本工作利用丙烯酸单体溶液聚合的方式,制备了一种转化率高、分子量较大的丙烯酸酯类均聚物低温成膜可剥离去污剂,并研究了交联剂、增塑剂、增稠剂、脱模剂等辅剂对可剥离核去污性能的影响,得到了最优化可剥离配方。通过试验测试分析了可剥离核去污剂材料的红外特性、玻璃化转变温度、聚合物分子量及去污效率等性能。研究结果表明,制备的低温成膜可剥离放射性去污剂可较好地在混凝土、沙土、水磨石、不锈钢等表面成膜,且易剥离,材料整体去污率在78%以上。

Abstract: In order to solve the technical problem of nuclear decontamination in low temperature environment, a new kind of low temperature film-forming detachable nuclear decontaminant was proposed. Acrylate homopolymer with high conversion and high molecular weight was prepared by solution polymerization of acrylic monomer. Based on the orthogonal test method, the orthogonal test of the effects of crosslinking agent, plasticizer, thickener, demoulding agent and other adjuvants on the decontamination performance of strippable nuclear detergent were carried out, and the optimal strippable formula was obtained. Then the infrared characteristics, glass transition temperature and polymerization of strippable nuclear decontaminant materials were studied through the test. The results show that the proposed low-temperature film-forming strippable radioactive decontamination agent can form film on concrete, sand, terrazzo, stainless steel and other surfaces, and it is easy to peel off. The decontamination rate of the material is more than 78%.

Key words: acrylic acid homopolymer low temperature film formation decontamination rate
