Description

一种抗燃汽轮机油及其制备方法
技术领域
本发明涉及有机物领域，具体涉及到一种抗燃汽轮机油及其制备方法。
背景技术
汽轮机油应用比较广泛，不论是火电厂的蒸汽轮机还是风机或者水轮机，都离不开汽轮机油的润滑。随着汽轮机的技术发展，汽轮机组也在不断地优化升级，现在越来越多的新进机组都采用600MW的超临界机组和1000MW的超超临界机组，发电装化容量增大，汽轮机负荷增加，汽轮机的运行温度也随之增加，因此对汽轮机油的燃点要求也在不断地提高。为了适应汽轮机在高负荷以及高运行温度的条件下，保证汽轮机的安全运行，拥有高闪点的汽轮机油便显得极其重要。高温高压重负荷耐辐射抗燃汽轮机油必须具备难燃性，同时具备良好的冷却性、调速润滑性和氧化安定性、更高自燃点、抗挥发性、低蒸气压，没有易燃维持燃烧的分解产物，不会沿油流传递火焰。并具有若因分解产物形成的蒸汽燃烧，也不会引起整个液体着火燃烧。若火焰切断后，会自行停止燃烧。应具有良好的热安定性和热氧化安定性、抗腐蚀性、抗乳抗泡性、水解安定性、辐射安定性、材料相溶性和溶剂效应。能被广泛应用核电站或大型火电站的超临界大型蒸汽轮机组中。
