Description

一种用于数控机床的阻燃型润滑脂
技术领域
本发明涉及润滑脂领域，尤其涉及一种用于数控机床的阻燃型润滑脂。
背景技术
采用阻燃材料，防止和减少火灾越来越受到我们国家重视，特别在井下煤矿、地铁、冶金等行业中防火安全更为突出，在我国，采煤机械用液压油规定使用的是抗燃液压油，其它像矿用电线电缆，运输胶带，煤矿用带式输送机托辊也逐步要求使用阻燃材料，而且制定了技术标准，我国煤炭行业在2006年制订的带式运输机托辊的标准中，对非金属托辊筒体和缓冲托辊胶圈规定了要通过阻燃性能技术条件，而其使用的润滑脂还未规定阻燃要求。但是，据了解我国煤矿安全部门要求其使用具有阻燃性润滑脂是势在必行的。
我们知道，润滑脂是一种可燃性物质，其组份90％是矿物油，矿物油的自燃点一般在250~350℃，很容易自燃，在井下，不仅电气设备运转不良会引起大火，机械设备运转不良，发生故障而产生局部持续的磨擦过热产生足够高于油的燃性温度，同样也可引起火灾。因此提高润滑脂的抗燃性能，对确保地下作业安全相当必要。另外，在冶金、炼铁、热轧等设备中润滑大多采用集中供脂，使用后废脂经常堆积在设备现场，在受到高温烘烤或高温碎片飞溅而引起起着火，容易发生火灾。
发明内容
本发明的目的是解决现有技术的不足，提供一种阻燃、降噪的润滑脂，具有突出的阻燃性、密封性。
本发明采用的技术方案是：一种用于数控机床的阻燃型润滑脂，其组分比例按重量份数计：
植物油60～79重量份
脂肪酸钙皂0.5～5重量份
锂皂增稠剂2.5～15重量份
无机稠化剂0.1～5.0重量份
分散剂0.5～5.0重量份
抗氧剂0.01～1.0重量份
阻燃剂0.1～8重量份
防锈剂0.1～0.5重量份
所述无机稠化剂为膨润土或二氧化硅，所述分散剂为丙酮，所述抗氧剂为二苯胺、二异辛基二苯胺或苯基～α～萘胺中的一种，所述防锈剂为石油磺酸钠或环烷酸锌，所述锂皂增稠剂具有一个或多个羟基和10个或更多个碳原子的高级羟基脂肪酸锂皂。
作为本发明的进一步改进，所述植物油为桐油。
本发明采用的有益效果是：本发明的润滑脂对金属表面具有优异的附着力。在使用中，在轴承金属表面上快速和均匀地形成保护膜。该保护膜可以保持在600℃热板不燃烧的阻燃性，这有助于轴承更长的使用寿命。此外，本发明在电机运转期间作用于密封轴承，使得噪音保持很低。本发明具有优良的机械安定性、抗水性、润滑性、防锈性、阻燃性，将会有更长的使用寿命，而且成本低。
