[0005] The chain oil used in the chain saw of the logging machine is a kind of total loss oil, and the adhesion performance of ordinary mechanical oil cannot meet the requirements of the logging machine.
At present, synthetic high-temperature chain oil is widely used in the market, but synthetic oil resources are scarce and the cost is high, and using it as high-temperature chain oil cannot be recycled, resulting in a lot of waste of resources and energy.

Abstract
The present invention provides a special lubricating oil composition for woodcutter chain saw mainly based on mineral oil, which is composed of the following components in weight percent: 0.05% to 4.0% of antioxidant, 0.01% to 4.0% of extreme pressure and antiwear agent 3.5%, rust inhibitor: 0.01-2.5%, thickener: 0-30%, base oil balance; the base oil is one of paraffin base oil, intermediate base oil and naphthenic base oil or a mixture of several. The special chain oil for logging machine chain saws based on mineral oil base oil according to the present invention has good extreme pressure and anti-wear properties, thermal stability and oxidation resistance, and also has excellent viscosity-temperature properties and low-temperature fluidity and adhesion.
Description
technical field [0001] The invention relates to a mineral oil type chain oil composition, in particular to a mineral oil type chain oil composition specially used for a wood cutting machine chain saw. Background technique [0002] The chain is one of the mechanical transmission components, it can transmit power accurately and stably, and it is an important component of the logging machine. The chain drive has strong adaptability, not only suitable for use at high torque and low speed, but also shows its superiority in corrosive and humid environments, as well as in high-speed transmission. Once the chain is not sufficiently lubricated during use, the pin shaft and the sleeve will be worn, resulting in misalignment of the chain and sprocket, increased noise, and elongated chain links. Therefore, in order to ensure the smooth and uniform operation of the chain drive, it is necessary to ensure the good performance of the chain lubrication system. [0003] The forestry harvest...
