Embodiment Construction

[0017] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] The production process of product of the present invention is example with 100kg test product, and production process is as follows:

[0019] Add about 30kg of low-viscosity ester oil base oil into the blending kettle, heat and stir to 100-120°C, add antioxidant and keep stirring for 30 minutes until the antioxidant is completely dissolved; add medium-viscosity ester oil and polyisobutylene, keep stirring 30 minutes until the solution is homogeneous and transparent; add the remaining amount of low-viscosity ester oil, add other additives at 80-90°C, and stir for 1 hour until the rust inhibitor and anti-wear agent are evenly dispersed. Filter the finished product with a 100-mesh stainless steel strainer.

[0020] The physical and chemical indicators of the finished product are tested by the following methods: GB / T265 petroleum p...

Abstract

The invention relates to high-temperature chain oil taking ester oil as base oil, wherein the chain oil comprises: (1) 30 to 50 percent of low-viscosity ester oil; (2) 30 to 50 percent of medium-viscosity ester oil; (3) 10 to 20 percent of polyisobutylene in specific molecular weight; and (4) 1.5 to 3.5 percent of antioxidants, 0 to 3 percent of antiwear agent and 0 to 1 percent of antirust agent. The viscosity of the high-temperature chain oil is 150 to 320 cst at 40 DEG C and is small in increasing trend at high temperature.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a composition for lubricating high-temperature conveying chains. technical background [0002] Chain drive is not only suitable for use under high torque and low speed, but also shows superiority in corrosive and humid environments, as well as in high-speed transmission. The smooth operation of the chain, the flexibility of the chain links, and the reduction of wear depend on the good lubrication effect of the chain lubrication system. The chain lubrication system must regularly and quantitatively inject high-temperature lubricating oil into the gap between the pin shaft and the sleeve of the chain To ensure good lubrication and normal operation of the chain. With the rapid development of my country's textile, printing and dyeing, petrochemical, building materials and transportation industries, the operating temperature of the transmission system of these equipment is getting higher and high...
