Description
技术领域
本发明涉及一种切削液及其制备方法,属于润滑油技术领域。
背景技术
切削液是一种在金属切、削、磨加工过程中用于冷却和润滑刀具及加工件的工业用液体,同时具备良好的冷却性能、润滑性能、防锈性能、除油清洗功能、防腐功能以及易稀释等特点。随着环境保护意识的增强,人们已经将不含油的水基合成切削液作为切削液发展的重要研究方向。水基合成切削液克服了传统皂基乳化液夏天易臭、冬天难稀释、防锈效果差的的毛病,对车床漆也无不良影响,适用于黑色金属的切削及磨加工,具有良好的冷却、清洗、防锈等特点,并且具备无毒、无味、对人体无侵蚀、对设备不腐蚀、对环境不污染等特点。
但是市场上大多数的水基合成切削液与油基切削液相比防锈性较差,如何提高水基切削液的防锈性是本领域的技术人员亟待解决的而技术问题。
发明内容
本发明要解决的技术问题是提供一种防锈性能十分优异的高防锈性切削液,以及该高防锈性切削液的制备方法。
本发明为解决上述技术问题提出的一种技术方案是:一种高防锈性切削液,包括以下质量百分比的组分:防锈润滑添加剂10%~20%,非离子表面活性剂1%~3%,1-羟基苯并***0.1%~0.5%,苯甲酸钠1%~5%,硼砂1%~3%,其余为水;所述防锈润滑添加剂是由35~45质量份的硼酸、15~25质量份的三乙醇胺、15~25质量份的乙醇胺、3~8质量份的氢氧化钠反应而成。
所述三乙醇胺与乙醇胺质量比为1:1。
所述三乙醇胺与硼酸质量比为1:2。
所述苯甲酸钠的用量是2.5%~3.5%。
所述1-羟基苯并***的用量是0.1%~0.3%。
所述非离子表面活性剂是OP-10和Span-80中的一种或两种。
所述非离子表面活性剂是OP-10和Span-80,且OP-10和Span-80的用量质量比为1:1~1.5。
本发明为解决上述技术问题提出的一种技术方案是:一种上述的高防锈性切削液的制备方法,将水加入反应釜中,然后加入硼酸和氢氧化钠,升温至90℃~95℃,保温搅拌20分钟~30分钟,再加入三乙醇胺和乙醇胺,保温搅拌2小时~3小时,待液体透明后加入非离子表面活性剂,搅拌20分钟~30分钟,温度控制在70℃~75℃加入1-羟基苯并***、苯甲酸钠和硼砂,继续搅拌20分钟~30分钟即可得到成品。
本发明具有积极的效果:本发明的高防锈性切削液由防锈润滑添加剂、防锈剂、非离子表面活性剂等复配而成,防锈润滑油性添加剂是硼酸与三乙醇胺和乙醇胺反应而成的水溶性油性剂,是具有亲水基团的长碳链物质,含有硼酸钠、三乙醇胺硼酸酯、乙醇胺硼酸酯等有效成分,在切削液中,易在刀具与切屑工件之间形成物理吸附膜,在较低负荷下起润滑作用,对于防锈性能的提升起关键性的作用。非离子表面活性剂使得切削液保持较低的表面张力,具有很好的清洗性,同时非离子表面活性剂采用OP-10或Span-80且用量较大,可以有效提升防锈性。1-羟基苯并***、硼酸、苯甲酸钠等防锈剂与防锈润滑添加剂协同作用,有利于进一步的提升防锈性,从而使得本产品的防锈性是其他产品的2倍左右,加工后的工件可以存放1至2个月。本发明的高防锈性切削液使用时用工业自来水配成2%~3%浓度的稀释液,循环使用,并定期添加。本发明的高防锈性切削液能确保工件的工序间防锈;优良的冷却性能,能及时带走磨削过程中大量磨削热,延长砂轮寿命;无不良气味,易***作工接受;润滑性好,能保证加工面精度和表面光洁度;耐腐败性能优异,使用周期长。适用于钢,铜,铸铁,铝及铝合金等多种金属的大多数机械加工方式,包括切削,磨削等。广泛应用于汽车,摩托车零部件加工及其它机械行业。特别适用于数控机床,加工中心等。
