Description

一种生物润滑油的制备方法
技术领域
本发明涉及润滑油技术领域，尤其是一种生物润滑油的制备方法。
背景技术
润滑油通常会用于压缩机中来减少摩擦，增强密封和移除汽缸及曲轴箱组件中的热量。汽缸润滑油由一种或多种抑制剂配制来帮助避免压缩机内部和工艺管路中其它处的乙烯聚合。该油润滑汽缸组件，该汽缸组件可以具有抵着固定表面移动的密封圈或在移动表面上带有的固定密封圈。由于在高压下产生的负荷，这些组件通常是金属的。这些润滑油的典型基础流体包括矿物油和多种合成油。加入添加剂用于抗腐蚀，金属钝化，抗磨，氧化稳定性，粘度改进，润滑，及其他的目的。
润滑油由基础油和添加剂两部分组成，基础油是润滑油的主要成分，决定着润滑油的基本性质，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，是润滑油的重要组成部分。
目前，在钢铁、汽车、一般器械、精密器械等各种产业领域中，大多使用以精制油或合成油为基油的润滑油。近年，为了满足器械装置的小型化、低电流化、长寿化，越来越要求提高润滑油的摩擦特性及耐磨耗性。另外，考虑到节能、成本、环境等观点，防止金属生锈显得越发重要，与之相伴，提高润滑油防锈性的要求也越来越高。
发明内容

为了实现本发明目的，本发明采用的技术方案如下：
一种生物润滑油的制备方法，其具体方法步骤为：1)在反应釜中加入蓖麻油、改性大豆油、甲基硅油搅拌混合均匀；2)依次继续加入缓蚀剂、抗氧化防腐剂、防锈复合油、氨基甲酸锌、有机钼、乙烯-丙烯共聚物，继续搅拌均匀，最后加入非离子型表面活性剂、油溶性纳米氧化锌继续搅拌均匀，得到所需润滑油。
