摘要

摘要本文介绍了航空聚硫和 VITEF-1B、VGM-L、VIKSINT U-20-99 和 VGF-2M 聚硅氧烷级密封材料的长期全气候试验结果。测试是在热带潮湿气候（中国海南岛万宁）和中温气候（格连吉克）的开放条件下进行的。为了分析弹性和强度降低的原因，还使用了在莫斯科、佛罗里达、亚利桑那和越南条件下进行的类似测试结果。结果表明，在辐射影响下，会发生破坏和交联反应，从而导致所研究材料的弹性发生变化。

Studies on the Climatic Resistance of Thiokol and Siloxane Sealant

Experimental results for the long-term full-scale climatic testing of aviation polysulfide and VITEF-1B, VGM-L, VIKSINT U-20-99, and VGF-2M polysiloxane grade sealing materials are presented. The testing have been carried out under open conditions of humid tropical climate characterizing Wanning (Hainan Island, China) and moderately warm climate characterizing Gelendzhik. In order to analyze the reasons for decreasing elasticity and strength, the results of similar testing under the conditions of Moscow, Florida, Arizona, and Vietnam have been used. It is shown that under the influence of radiation, destruction and cross-linking reactions occur that lead to the change in the elasticity of the studied materials.
