Description

环境友好型水基柱塞冲头润滑液
技术领域
本发明涉及一种柱塞冲头润滑液，尤其涉及一种环境友好型水基柱塞冲头润滑液。
背景技术
从上世纪八十年代开始，随着汽车、电子通讯、家用电器、重型制造业的飞速发展，金属压铸件的需求量不断扩大，对压铸件的质量也提出更高要求。在压铸过程中，压铸机柱塞冲头与金属熔融液直接接触，冲头处于高温、高压、高摩擦条件下长期工作，对金属压铸成型过程必须保证良好的冷却和润滑，才能保证金属压铸件的表面质量，减低柱塞头和输料管之间的摩擦，延长柱塞头和型腔的使用寿命。传统金属压铸柱塞冲头润滑剂普遍使用冲头油，主要成分为矿物油及耐高温的抗磨润滑剂组成，其中以耐高温性能稳定的石墨抗磨剂被广泛应用于金属压铸柱塞冲头油中。油性冲头油与温度高至数百度的金属熔融液接触时会产生燃烧，散发出大量烟雾及对人体有害的刺激性气体，含有石墨材料的冲头油更对工作环境造成严重污染。近年来市场上出现了一些乳化型水性冲压润滑剂，这类润滑剂含有大量的矿物油及油溶性的有机抗磨添加剂，同样还会出现油烟雾的污染及压铸件、柱塞头、输料管的油垢污染。
本世纪以来，国际上对环境保护的要求愈来愈严格，降低工业加工对环境的污染呼声更加强烈，开发一种不含矿物油、具有良好的高温冷却、润滑、稳定的环境友好型水基柱塞冲头润滑液就十分迫切了。
