具体实施方式
为了便于理解本发明，下面将对本发明进行更全面的描述。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
本发明提供一种排锯丝杆润滑脂，包括如下组分：500N(二类油)、稠化剂、乙丙共聚物、硼酸盐及二苯胺；所述稠化剂为单水氢氧化锂、硬脂酸与十二羟基硬脂酸的组合物。
该排锯丝杆润滑脂，根据排锯丝杆在使用过程中的工况进行专门设计，采用矿物油500N(二类油)，配合组合后的稠化剂，加上适配的抗氧剂、增粘剂、抗磨剂成分，形成专用的排锯丝杆润滑脂，从而在使用时不再需要人工配制，减少了人力成本；该润滑脂运动粘度远大于混配的润滑脂，有助于润滑脂更好的附着在排锯丝杆表面，不易流失；锥入度较小，流动性更小，损耗更少，使用量在较少的情况下可以达到相应的效果，减少浪费。
一实施例中，单水氢氧化锂、硬脂酸与十二羟基硬脂酸的质量比为0.05-1.5：0.05-2：1-5。其中每个稠化剂的化学结构有差别，其功能也有细微 差别，采用该质量比形成组合物，可以较好地与矿物油适配，而且在达到其稠度、粘度要求的前提下，减少稠化剂的用量。
进一步地，单水氢氧化锂、硬脂酸与十二羟基硬脂酸的质量比为0.1-1：0.1-2：1-3。
再进一步地，在具体的实施过程中，单水氢氧化锂、硬脂酸与十二羟基硬脂酸的质量比为0.5：1：2。即十二羟基硬脂酸用量较多，单水氢氧化锂用量较低。
一实施例中，上述的排锯丝杆润滑脂，包括如下重量份的组分：500N(二类油)60-100份、单水氢氧化锂0.05-1.5份、硬脂酸0.05-2份、十二羟基硬脂酸1-5份、乙丙共聚物1-5份、硼酸盐1-5份及二苯胺0.2-2份。根据排锯丝杆在使用过程中的工况进行专门设计，使用上述的质量配比，其效果较佳，成本相对较低。
优选地，上述的排锯丝杆润滑脂，包括如下重量份的组分：500N(二类油)70-90份、单水氢氧化锂0.1-1份、硬脂酸0.1-2份、十二羟基硬脂酸1-3份、乙丙共聚物1-4份、硼酸盐1-3份及二苯胺0.5-1份。
本发明还提供一种所述的排锯丝杆润滑脂的制备方法，包括如下步骤：
将500N(二类油)、硬脂酸、十二羟基硬脂酸加入反应装置中，搅拌加热至90℃-96℃，将单水氢氧化锂稀释3-6倍后加入所述反应装置中；
将所述反应装置内加热至200℃-220℃，开启搅拌及循环剪切；
第一时间后，将所述反应装置降温至90℃-95℃，加入乙丙共聚物、硼酸盐及二苯胺，反应；
第二时间后，转移脱气。

表一
Figure PCTCN2021137125-appb-000001
由表一可以看出，实施例一至实施例五的排锯丝杆润滑脂，运动粘度均在1500左右，有助于润滑脂更好的附着在排锯丝杆表面，不易流失，从而减少损耗，降低使用成本；锥入度相对较小，流动性更小；而各对比例的润滑脂，运动粘度在400-900之间，远小于各实施例，锥入度相对各实施例较大，因此，在流失率以及使用效果上，均不及本发明各实施例，尤其是对比例四，采用混配的润滑脂，效果较差。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改 进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
