Problems solved by technology

This type of open gear oil contains more than 80% asphalt residue and has poor viscosity-temperature properties, so it is limited in the production of products with high viscosity, low pour point and high viscosity index

Effect test

example 1

[0030] Add 466 grams of molten No. 100 B road asphalt into the blending kettle, add 3.8 grams of butadiene rubber (dissolved with heavy alkylbenzene first), 61 grams of lead naphthenate, 30 grams of T405A and 1 # 199.2 grams of solvent, and make the temperature in the still down to 60 ℃ and then add 240 grams of 2 # Solvent (ethylene dichloride), mix well to get S-Pb diluted open gear oil. The product performance is shown in Table 2.

example 2

[0032] Add 507 grams of molten No. 60 B road asphalt into the blending kettle, and then add 11.7 grams of butadiene rubber (dissolved with heavy alkyl benzene first) and 6044B sulfur phosphorus extreme pressure under the condition of 85±5°C and stirring. Anti-wear agent 15 grams, 1 # Solvent 223 grams, add 2 # Solvent (trichloroethane) 243.3 grams, mix to get S-P type diluted open gear oil. The product performance is shown in Table 2.

example 3

[0034] By the method of example 1, 447.1 grams of No. 100 asphalt and 11.4 grams of butadiene rubber, 17.9 grams of 6044B sulfur phosphorus type extreme pressure antiwear agent, 1 # Solvent 213.6 grams, 2 # 310 grams of solvent (trichlorethylene) were uniformly mixed to obtain S-P type olefin-release open gear oil. The product performance is shown in Table 2.

Abstract

The invention is an open gear oil, which is based on petroleum asphalt, adhesive agent, extreme pressure anti-wear agent, heavy alkyl benzene solvent and containing methane chloride, ethyl chloride and vinyl chloride. 2 # Solvent, mixed to obtain dilute open gear oil, it is not necessary to add 2 # Solvent, made ordinary open gear oil. Because the present invention adopts heavy alkyl benzene solvent, the shortcoming that the viscosity-temperature property of road asphalt is very poor is improved, and the open gear oil prepared according to the technology of the present invention, its extreme pressure anti-wear performance, low temperature performance and high temperature performance are equal to The same kind of gear oil is good, and dilute open gear oil and ordinary open gear oil with higher viscosity can be obtained at the same time, which expands the product variety and can fully meet all the requirements of large mining machinery and other open gear lubrication.

Description

technical field [0001] The invention belongs to lubricant technology, in particular to an open gear oil composition, more precisely a solvent-diluted open gear oil composition and a common open gear oil composition. Background technique [0002] Open gear lubricants are a specialized class of lubricants that have been around commercially for many years. As the name suggests, gears are lubricated in the open air or exposed to the atmosphere, so gear oil must be resistant to moisture or rain washing, and to adapt to a wide range of temperature changes. The fluidity of the gear oil should be moderate, easy to brush, easy to spray, and easy to operate. In addition, the formed oil film must also have certain anti-wear and extreme pressure properties, and has the characteristics of dustproof and not easy to lose. The prior art cannot fully meet the above requirements, and there is no uniform standard for dilute open gear oils. [0003] As early as the 1950s, U.S. Patent No. 2,8...
