Description

一种耐高温导热油
（一）技术领域
本发明属于化工技术领域，特别涉及一种耐高温导热油。
（二）背景技术
耐高温导热油是一种重要的、技术含量很高的石油产品，与汽油、煤油、柴油、燃料重油等石油产品相比，它虽然数量较少，但是品种、规格却非常多。
耐高温导热油主要起润滑、冷却、防锈、清洁、密封和缓冲等作用。耐高温导热油由基础油和添加剂两部分组成，基础油是耐高温导热油的主要成分，决定着耐高温导热油的基本性质，添加剂则可弥补和改善基础油性能方面的不足，赋予某些新的性能，是耐高温导热油的重要组成部分。现有的耐高温导热油寿命低，无法长期循环使用，无法满足许多场合的需求，导致设备耗损大。
（三）发明内容
本发明为了弥补现有技术的不足，提供了一种耐高温导热油。
本发明是通过如下技术方案实现的：
一种耐高温导热油，其特征在于，包括以下重量份数的组份：基础油80-120份，清净剂1-3份，分散剂5-8份，高温抗氧剂5-10份，阻焦剂1-3份，降凝剂1-3份，降粘剂1-3份，金属减活剂1-2份。
