Description

环保型钢丝绳润滑脂及其制备方法
技术领域
本发明涉及一种环保型钢丝绳润滑脂，属于润滑技术领域。
背景技术
钢丝绳的强度高、自重轻、工作平稳、不易骤然整根折断，工作可靠，在国民经济中发挥着巨大的作用。钢丝绳工作时，同时受到压力、拉力、扭力、剪力、摩擦力及疲劳应力等作用，而且用于船舶上的钢丝绳，处于湿度很大的环境中，加上海水和江水的飞溅，钢丝受海水、江水及湿气的侵蚀，空气中的氧气和水分渗透过金属表面的防护层，引起钢丝表面氧化即锈蚀，致使钢丝绳的使用性能及寿命大大降低。
用于港口、船舶上的常规钢丝绳使用部位要求钢丝绳润滑脂要有较强的粘附能力，防止使用时被甩流，良好的渗透性能，良好的防锈，防腐蚀性能，优良的水安定性，还要保证日晒不流失，温度低时有韧性，不脆裂脱落，以起到保护作用，最重要的是还需要润滑脂可降解、对环境无污染。
目前国内常用的钢丝绳润滑脂附着力差，使用性能和效果往往满足不了实际需求，在使用过程中造成很大的浪费和环境污染，影响钢丝绳的使用寿命。
发明内容

优选的，增粘剂选自乙丙共聚物、聚异丁烯、聚丙烯酸酯、聚氨脂、聚醋酸乙烯等中任意一种或几种，优选聚丙烯酸酯、聚异丁烯、乙丙共聚物一种或组合。
与现有技术相比，本发明的优点是：
(1)本发明具有优异的抗盐雾和湿热性能和高低温性能、突出的黏附性，降解率高，对环境资源无危害，适用于港口机械、船舶辅机等海洋盐雾潮湿环境下的钢丝绳润滑。
(2)本发明在烃基润滑脂中加入聚脲润滑脂，制成特定稠度的半流体钢丝绳润滑脂，提高产品的滴点、抗盐雾、抗辐射、防水性和防护性能，解决现用产品的高温流淌、低温开裂、腐蚀生锈等问题，并且所使用的基础油为低凝点、可降解基础油，降解率高，对水资源及生物资源无危害。
(3)本发明的钢丝绳润滑脂的渗透式涂敷时，长时间150℃高温下不分油，且长时间高温作用后，仍能保持高温85℃下不流淌，低温-40℃不脆裂的性能，不含挥发性溶剂，涂敷方便，生产成本低，提高润滑效果，能有效满足运行中钢丝绳内、外部的润滑和防护要求。
