Description

添加剂组合物及其用途
技术领域
本发明涉及一种添加剂组合物及其用途。
背景技术
搓丝机，是生产螺栓，螺钉类紧固件以及外圆周螺纹的专用机械设备。搓丝机的工作原理是：有一块活动搓板和一块固定搓丝板进行工作。活动搓丝板来回运动，当搓丝板活动向前，送入的坯料被夹在活动搓丝板与固定搓丝板之中被活动搓丝板带动，旋转着向前移动，在活动搓丝板与固定搓丝板之间碾出螺纹。安装活动搓丝板的滑块往复一个来回，搓出一个工件。搓丝板往返一次一条螺栓螺纹就加工完成了，加工速度快，螺纹强度高，搓丝多用于小型螺栓加工，加工效率优于切削产生的螺纹。
目前搓丝机常用的润滑油主要为矿物油型工业用油，普遍使用机械油、液压油等润滑油品种，这些润滑油都不是针对搓丝机的工况开发的润滑油，存在抗磨性偏低，加工过程产生的油雾量比较大的问题。由于搓丝加工过程中，润滑油要经历泵循环、喷雾、射流和高温蒸发等过程，因此会产生大量油雾，这些油雾以很小的颗粒悬浮在空气中，其中直径小于5μm的油雾颗粒能够伴随操作工人的呼吸过程到达人体肺泡，并在肺部沉淀，从而造成对人类健康的危害。随着环境保护和职业保护等方面的法规要求越来越高，需要对加工车间的油雾浓度进行有效的控制。降低加工车间空气中的油雾含量通常有两种方法，一种是尽量减少已经形成的油雾，如使用排风泵、油雾捕集器等进行机械降雾；另一种则是使用低油雾型加工润滑剂。由于使用油雾捕集器等设备的成本非常惊人，因此使用低油雾型加工润滑剂成为有效降低车间油雾浓度的有效途径。
发明内容
本发明所要解决的技术问题现有技术中搓丝机润滑油使用时油雾浓度高的问题，提供一种新的添加剂组合物。该添加剂组合物用于调制用于搓丝剂的润滑油时，具有油雾浓度低的特点。
为解决上述技术问题，本发明采取的技术方案如下：一种添加剂组合物，以重量份数计由以下组份组成：
a)10～20份高黏度指数矿物油；
b)10～50份抗氧防锈添加剂组合物；
c)2～10份抗磨剂；
d)30～65份高分子聚合物添加剂；
所述矿物油为异构脱蜡加氢基础油或深度精制矿物油中的至少一种；
所述抗氧防锈添加剂组合物为LZ5703、LZ5404、LZ5186、H521、H543、H2571、IR5010、IR2030或OLOA4994中的至少一种；
所述抗磨剂为硫代亚磷酸酯、硫代亚磷酸胺盐、磷酸酯胺盐、硫代磷酸酯、二烷基二硫代磷酸锌盐及其衍生物中的至少一种；
所述高分子聚合物添加剂为聚甲基丙烯酸酯、聚异丁烯、聚丁二烯或乙烯丙烯共聚物中的至少一种。
本发明还提供一种所述添加剂组合物的用途。所述添加剂组合物用于调配搓丝机用润滑油。所述添加剂组合物加入比例以重量百分比计为2～5％。
本发明组合物中，所述高黏度指数矿物油为异构脱蜡加氢基础油，或深度精制矿物油，或以上组分的组合物。
本发明组合物中，所述抗氧防锈添加剂组合物为抗氧剂和防锈剂等多种添加剂的混合物，如LZ5703、LZ5404、、LZ5186、H521、H543、H2571、IR5010、IR2030、OLOA4994等。其加入量控制在0.5～5.0份，其加入量应控制在合适的范围内，加入量过大和过小都会造成其性能达不到预期效果。
本发明组合物中，所述抗磨剂为硫代亚磷酸酯，或硫代亚磷酸胺盐，或磷酸酯胺盐、或硫代磷酸酯、或二烷基二硫代磷酸锌盐及其衍生物，或以上组分的混合物，比如T304、T305、T307、T308、Irgalube 353、Irgafos OPH、T203、T205等。其加入量控制在0.1～2.0份，由于此类添加剂与其它添加剂有复配效应，其加入量应控制在一定范围内，才能达到合适的综合性能。
本发明组合物中，所述高分子聚合物添加剂为聚甲基丙烯酸酯，或聚异丁烯，或聚丁二烯，或乙烯丙烯共聚物，或以上组分的混合物。如平均分子量大于30000的PMA，平均分子量大于2000的PIB，平均分子量大于40000的OCP。其加入量控制在0.1～2.0份，当加入量过小时，油品的抗油雾性能达不到要求；当加入量过大时，可能对油品其它性能产生影响。
本发明所述添加剂组合物的制备方法，其包括如下步骤：
1)按比例加入基础油、高分子聚合物添加剂，升温至70～80℃进行加热搅拌，维持1～3小时后，将温度降至45～55℃；
2)再加入其他成分，搅拌2～3小时，至混合物全部溶解呈透明状态。
为了评价此组合物的性能，将其与基础油调配成搓丝机润滑油，开展如下评价测试：
石油产品铜片腐蚀试验法(GB/T 5096)，润滑油防锈性试验(GB/T11143)，润滑剂承载能力测试法(四球机法)(GB/T 3142)，润滑油泡沫特性测定法(GB/T 12579)。
本发明研究人员经过大量实验研究，选择适合的基础油及与其相配伍的添加剂，并摸索了各添加剂种类及配比，得到的添加剂组合物，与基础油混合，调配成搓丝机用润滑油，润滑油具备良好的抗磨性能、防锈性和低油雾性，可用于搓丝机的润滑。
下面通过实施例对本发明作进一步的阐述。
具体实施方式
【实施例1～3】
加入基础油、高分子聚合物添加剂，升温至75℃进行加热搅拌，维持2小时后，将温度降至50℃；再加入抗氧防锈添加剂组合物、抗磨剂，搅拌2小时，至混合物全部溶解呈透明状态，制得本发明所述组合物。组合物具体组分见表1。
表1
分别采用【实施例1～3】调配搓丝机用润滑油，具体组分及产品性能表现见表2。
表2
如表2中测试结果，采用【实施例1～3】调配的搓丝机用润滑油的防锈性试验、铜片腐蚀、四球试验均表现良好，完全能够满足搓丝机搓丝加工的要求。同时三个搓丝机润滑油的油雾浓度测试结果都在2.0mg/m3以下，明显低于普通的搓丝机用润滑油4.0mg/m3以上的油雾浓度，说明油品具有良好的抗油雾性能，降低在加工现场因油雾浓度过高对操作工人健康的伤害。
