金属半膜橡胶防热层粘接技术研究

对TA1金属半膜的防热层粘接工艺进行了研究，从粘接方案选择、隔热材料选择、胶粘剂选择、粘接试验及试验验证等方面进行了分析与研究。研究表明：9621橡胶可以作为TA1金属半膜的隔热材料，2种材料可以用DG-2环氧胶粘剂进行热硫化粘接。带有防热层的TA1金属半膜可以耐受短时（240s）〈500K的温度，半膜内部的液腔温升几乎为零，有效防护了高温对半膜内部液体的不利影响。

Technology to bond metal semisphere diaphragm to rubber heat insulation layer

The process to bond the TA1 hemisphere diaphragm to the rubber heat insulation layer is studied in this paper. The research mission in the aspects of selection of bonding solution, selection of heat insulation material, selection of adhesive, bonding test and experimental validation was performed. The results show that rubber 9621 can be used as the heat insulation material of TA1 semisphere diaphragm, and the rubber 9621 and TA1 hemisphere diaphragm can be bonded by epoxy adhesive DG-2. TA1 hemisphere diaphragm with heat insulation layer can tolerate the temperature〈500 K and the temperature rise inside the TA1 hemisphere diaphragm is almost zero within 240 s. The result shows that the heat insulation layer can preserve the liquid inside the metal hemisphere diaphragm to suffer from the disadvantageous effect of high temperature.
