High-temperature chain lubricant and preparation method thereof

Abstract

The invention discloses a high-temperature chain lubricant and a preparation method thereof. The high-temperature chain lubricant is composed of the raw materials of, by weight: 70-90 parts of base oil, 10-20 parts of calcium petroleum sulfonate, 0.1-0.3 parts of ethanol, 0.4-0.8 parts of petroleum ether, 1-2 parts of fatty acid, 0.4-0.8 parts of boric acid, 0.6-1 part of water, 1-2 parts of calcium hydroxide, 0.5-1 part of calcium carbonate, and 0.2-0.5 parts of a high-temperature antioxidant. The high-temperature chain lubricant preparation method comprises the steps that: base oil accounting for 30-40% of the total amount of the base oil, calcium petroleum sulfonate, ethanol, petroleum ether, fatty acid, boric acid, water, and calcium hydroxide are sequentially added and are subjected to a saponification reaction; and calcium carbonate and the rest of the base oil are added for refining. The lubricant provided by the invention has excellent high-temperature thermal stability, excellent anti-oxidation stability, good lubrication performance, good permeability, good extreme-pressure wear resistance, and good adhesion. The preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to a lubricant and a preparation method thereof, in particular to a high-temperature chain lubricant and a preparation method thereof. Background technique [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-resistant lubricant 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 ...

Problems solved by technology

The high-temperature chain lubricants in the prior art have always been based on synthetic oil and added with functional additives for production and use. Some products using thickeners do not have anti-rust, extreme pressure and anti-wear properties. It is also necessary to add functional additives to improve, but there are problems: some synthetic oils with low freezing point and high viscosity index have low viscosity, low flash point, easy to decompose, and large volatility, and the higher the flash point, the greater the viscosity and the low temperature performance. At the same time, most of the functional additives such as tackifiers, anti-rust agents, extreme pressure and anti-wear agents currently used in the market will decompose into gas and coke with high ash content under high temperature conditions, and will also occur after contact with water. Hydrolysis not only loses the original performance, but also causes equipment corrosion and environmental pollution, which cannot guarantee the normal use of high temperature chain lubricants
