摘要

研制了一种高性能潜水用泡沫氯丁橡胶,并对其在QUV加速老化箱和温度循环箱中的老化行为进行了研究。结果表明:经过9d QUV加速老化后,由于发泡孔出现明显的裂纹,材料的抗拉强度和撕裂强度下降;在温度循环中,由于时效过程中的交联反应,材料的力学性能有所提高。此外,采用介电通量智能测试仪对材料的抗氯离子渗透性能进行了测试,结果表明该材料具有优异的抗氯离子渗透能力。渗透系数为8.1×10-11cm2/s。

Study of High-Performance Chloroprene Sponge in Diving Suit Application
A diving-suit-used foam neoprene with high performance has been developed and its aging behaviors in QUV accelerated aging tank and temperature cyclic chamber were investigated. The results show that the tensile strength and tear strength of the material are decreased after 9d QUV accelerated aging due to the obvious cracks in the foaming cell. In temperature cycling the mechanical properties increased arising from cross linking reaction in the aging process. Besides, the chloride ion penetration resistance of the material was tested by dielectric flux intelligent tester, and the result shows that the material is of excellent chloride ion penetration resistance capability. The infiltration coefficient is 8.1×10-11cm2/s.
