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

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 199.2 grams of 1# solvent, and after the temperature in the kettle was lowered to 60°C, 240 grams of 2# solvent (ethylene dichloride) was added, and mixed well to obtain the S-Ph type 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. 15 grams of anti-wear agent, 223 grams of 1# solvent, add 243.3 grams of 2# solvent (trichloroethane) after the temperature in the kettle drops to 60°C, and mix well to obtain 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

Disclosed is an open type gear oil comprising asphalt based basic oiling material, adhesive, extreme pressure antiwearing agent, heavy alkyl benzene solvent and 2# solvent including chlorine-containing methane, chlorine-containing ethane and chlorine-containing ethane. The open type gear oil is prepared through mixing the components.

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...
