Description

Technical Field

[0001] This invention relates to the field of lubricating oil technology, and in particular to a baler oil composition and its preparation method. Background Technology

[0002] Baler oil is mainly used in the hydraulic tank of baler, and plays a role in transmitting energy, reducing friction, cooling, preventing corrosion and rust.

[0003] Balers are mainly used in Northeast China, Inner Mongolia, Xinjiang, and Hebei Province. In Northeast China, the operating season lasts from November to early April of the following year, a total of about five months, with long intervals between seasons. Balers operate primarily in autumn and winter, and the working environment is harsh, requiring high performance in terms of low-temperature and shear resistance of the oil. Therefore, developing a baler oil with good low-temperature performance and shear stability is of great significance for the use of balers in harsh conditions in cold regions. Summary of the Invention

[0006] In the above-described scheme, the baler oil composition of the present invention includes base oil, composite additives, viscosity index improvers, pour point depressants, and antifoaming agents. The viscosity index improvers enhance the viscosity-temperature properties of the baler oil composition, resulting in a baler oil composition with good low-temperature starting performance and maintaining appropriate viscosity at high temperatures. The pour point depressant rapidly lowers the pour point of the oil composition, further improving its low-temperature fluidity. The antifoaming agent prevents foam formation in the baler oil composition, avoiding adverse effects on the production process and preventing defects caused by foam. The composite additives include various additives such as antioxidants, corrosion inhibitors, rust inhibitors, anti-wear agents, and metal deactivators, further enhancing the overall performance of the baler oil composition. By limiting the dosage of each component within a reasonable range, better synergistic effects are achieved between the components, giving the baler oil composition excellent low-temperature performance and shear stability, ensuring normal operation of the baler under harsh conditions in cold regions.
