Description

一种金属加工用环保型高水基切削液
技术领域
本发明涉及切削液领域，具体的说是一种金属加工用环保型高水基切削液组合物。
背景技术
机械加工特别是金属加工过程的工序中车铣刨磨经常需要润滑，此外还需要将加工过程中碎屑清洗，将加工过程产生的高温冷却，还要防止金属在加工过程的生锈，因此，通常都需要切削液的参与。按照分散相分，切削液主要包括水基切削液和油基切削液两种。近年来水基切削液由于清洁、冷却效果好受到广泛欢迎。然而现有的水基切削液的润滑及防锈性能有待改善，且存在储存后容易发臭等问题，为此经常将其中加入各种辅助添加剂，导致了成本增加、切削液稳定性受到影响。此外，许多切削液中还包含了国家明令禁止使用的亚硝酸盐等三致物质，这些切削液的使用对环境和接触人员造成了极大的威胁，尽管也有一些环保型切削液的报道，但往往成分较复杂，导致成本较高，应用受到限制。
发明内容
本发明目的就是要提供一种金属加工用环保型高水基切削液，具有良好的润滑、冷却、清洗和防锈性能，使用周期长，不易分层或变味，并能提高加工质量和加工效率。
为解决上述技术问题，本发明通过以下技术方案来实现：
一种金属加工用环保型高水基切削液，是由以下重量份数的原料组成：精制生物油5～20份，去离子水1000份，胶体石墨粉0.1～3份，纳米二氧化钛0.1～2份，亚硫酸钠10～50份，二辛基丁二酸磺酸钠5～20份，正十一醇0.6～8份。其中所述的精制生物油为生物质快速热解液化所得生物油在1.2～1.5kPa下减压蒸馏收集的54～64℃的馏分；胶体石墨粉粒径为20～50nm；纳米二氧化钛粒径为80～120nm。
优选的，上述金属加工用环保型高水基切削液，是由以下重量份数的原料组成：精制生物油8份，去离子水1000份，胶体石墨粉0.2份，纳米二氧化钛0.5份，亚硫酸钠22份，二辛基丁二酸磺酸钠16份，正十一醇5.3份。其中所述的精制生物油为玉米秸秆快速热解液化所得生物油在1.3～1.5kPa下减压蒸馏收集的60～62℃的馏分；胶体石墨粉粒径为30～40nm；纳米二氧化钛粒径为90～100nm。
与现有技术相比，本发明的有益效果是：
1)本发明的产品环保，可生物降解。产品不含亚硝酸盐等有害物质，所有成分均符合国家环保要求。
2)本发明的产品稳定时间长、不易发臭。各组分之间不会发生化学反应，且各组分的作用不会相互影响。
3)本发明的产品润滑、清洗、冷却和防锈效果好。本发明的产品可明显改善包括铸铁、不锈钢、铝合金等多种材质的加工表面质量与加工效率，降低刀具磨损。
4)本发明的产品的组成简单，成本较低。本发明产品中各添加剂含量较低，组分也不复杂，容易规模化放大生产。
