Embodiment 1～8

[0037] Using detergent, dispersant, antioxidant, pour point depressant, antirust agent, viscosity index improver, and HVI base oil as raw materials to prepare various formulations of dual-purpose oil for lubrication and antirust of oil-containing bearings, the composition of each formulation is shown in the table 1. The above mixture was heated and stirred at a temperature of 50-60° C. for 1 hour until completely homogeneous.

[0038] The following tests are used to investigate the performance of oil products: kinematic viscosity (100°C) indicates the internal friction of the oil when it flows at 100°C, and represents the viscosity of the oil, the higher the value, the greater the viscosity; the low temperature dynamic viscosity (-20°C) indicates the oil The internal friction of the product at -20°C indicates the cold start performance of the oil at low temperature. The lower the value, the better the cold start performance; The safety index of the product, the higher the val...

Abstract

The invention relates to application of a lubricating oil composition. The composition comprises the following components in parts by weight: a) 1-10 parts of detergent, b) 1-15 parts of dispersing agent, c) 1-10 parts of antioxidant, d) 0.03-2 parts of pour-point depressant, e) 0.01-2 parts of rust inhibitor, f) 0.05-10 parts of viscosity index improver and g) 50-90 parts of base oil. In the composition, the calcium content is not less than 2500 ppm, the zinc content is not less than 900 ppm, and the phosphorus content is not less than 800 ppm; and thus, the composition can satisfy the SHRHYXY15259-2013 quality grade requirements and is used for lubrication and rust prevention of micromotor oil-retaining bearings.

Description

technical field [0001] The present invention relates to the use of a lubricating oil composition. Background technique [0002] With the application and development of copper, iron and other (and) various metal processing technologies, new requirements are put forward for the lubricating performance of processing equipment and components, especially the antirust performance. [0003] Document CN102459705A discloses an antirust oil composition, which is characterized in that it contains 0.1-10% by mass based on the total amount of the composition, and a non-ionic surface active oil with a hydrophilic-lipophilic balance value of 10-12 and selected from sarcosine type compounds, sulfonates, esters, amines, carboxylic acids, fatty acid amine salts, carboxylates, paraffin wax, oxidized wax salts, alkyl or alkenyl succinic acid derivatives and boron compounds At least one anti-rust additive in. [0004] Document CN102952307A discloses an antirust composition, which is characteri...
