Problems solved by technology

[0003] However, the engine lubricating oil of traditional forklift bearings tends to turn black shortly after use, because the engine lubricating oil continues to clean up the carbon particles. When the oxygen in the air interacts with the engine oil, thick black carbon mud particles will be produced. On engine parts, the higher the engine speed and temperature, the faster the decomposition rate. Oxidative decomposition will not only cause damage to the engine, but also block the oil pipe, resulting in the failure of oil to be delivered to the engine, increasing the maintenance cost of the equipment. reduced engine life

Abstract

The invention relates to the field of lubricating oil for forklift bearings and particularly relates to dibutyl maleate and methylcellulose mixed lubricating oil special for forklift bearings. The lubricating oil is composed of the following raw materials in parts by weight: soybeans, a mixture of modified amine and polyamide, butyl acrylate, methylcellulose, hydroquinone, acrylic acid, ethyl cyanoacetate, solid formaldehyde, vinyl acetate, tricresyl phosphate, dibutyl maleate, naphthenic base oil, an anti-wear agent, an anticorrosive antirust agent, a clean factor, an antioxidant, metal deactivator, a viscosity modifier, pyridine and sodium persulfate. Good viscosity index and high wear resistance can be ensured while the cost of the base oil is controlled; the thermal conductivity of thelubricating oil can be improved due to the addition of the soybeans and methylcellulose, the lubricating oil is excellent in resistance to emulsion and foam resistance, while the air release propertyof the lubricating oil is not ideal.

Description

Technical field: [0001] The invention relates to the field of lubricating oil for forklift bearings, in particular to a lubricating oil for forklift bearings in which dibutyl maleate is mixed with methyl cellulose. Background technique: [0002] Lubricating oil is an oily liquid coated on the surface of machine bearings. According to its source, it is divided into four categories: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. It has the functions of reducing friction, avoiding heat, and preventing machine wear. [0003] However, the engine lubricating oil of traditional forklift bearings tends to turn black shortly after use, because the engine lubricating oil continues to clean up the carbon particles. When the oxygen in the air interacts with the engine oil, thick black carbon mud particles will be produced. On engine parts, the higher the engine speed and temperature, the faster the decomposition rate. Oxidative decomposition will not...
