| 摘 要： | 以喷涂聚脲弹性体技术为依托,合成NCO%在13~14的芳香族聚脲半预聚物(A组分),在B组分中引入适当比例的长链氨基聚醚和位阻型胺类扩链剂,设计合适的工艺参数制备出一种低模量、高伸长率的聚脲柔性减阻涂层。与传统的硅胶、PVC、聚氨酯、丙烯酸等减阻涂层相比,该涂层具:①耐冲击,附着力好;②密度与水基本相同;③模量低,阻尼小;④涂层致密,不透水等重要特点。经中国船舶科学研究中心测试,在3 m/s~10 m/s时平板上1 mm的柔性减阻涂层可降低阻力6%以上。

| Abstract: | Based on the technology of the spray polyurea elastomer(SPUA),a new polyurea compliant coating synthesis method for drag-reducing and noise-reducing technique was applied.The system consists of the A component,a quasi-prepolymer 13%~14% of free NCO,and the B component,a mixture of polyetheramine,amine extenders and other additives.The features of the new material:(1) high adhesion and impact resistance;(2) low modulus and high elongation;(3) seamless,flexible.The sample of SPUA compliant skin were tested repeatedly in a cyclic water tank.Several samples of drag-reducing 6%~7% have been obtained in 3 m/s~10 m/s. |
