Abstract
The invention relates to the technical field of lubricating greases and discloses a composition of an electronic sewing machine driving mechanism lubricating grease. The composition comprises the following components in percentage by mass: 75-80% of basic oil and 20-25% of a thickening agent, and the following additives in percentage by mass are put into the composition according to the total amount of the two components: 2% of a dispersant, 3% of an extreme pressure anti-wear reagent, 2% of an antirusting agent, 1% of an antioxidant and 5% of a solid lubricant. The preparation method of the composition of the electronic sewing machine driving mechanism lubricating grease comprises the following steps: respectively putting 75-80% of water-soluble polyether, 20-25% of a composite lithium soap and 2.5-3.5% of dialkyl molybdenum dithiocarbamate into a reaction kettle, starting stirring, heating to 95-100 DEG C, stirring for 60 minutes, increasing the temperature to 130-140 DEG C, and stirring for 40-60 minutes. The obtained electronic sewing machine driving mechanism lubricating grease has excellent adhesiveness, load resistance, shearing resistance, wearing reduction and rusting erosion resistance, and is applicable to contact friction of metals within a temperature range of minus 30 DEG C to 180 DEG C and plastics or metals and metals.
Description
technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a composition and a preparation method of lubricating grease for driving mechanisms of electric sewing machines. Background technique [0002] The English name of grease is thick grease-like semi-solid, which is used for the friction part of machinery to lubricate and seal. It is also used on metal surfaces to fill gaps and prevent rust. It is mainly composed of mineral oil (or synthetic lubricating oil) Prepared with a thickener. [0003] The traditional electric sewing machine driving mechanism has poor grease adhesion. During the operation of the electric sewing machine driving mechanism, it is prone to oil leakage and serious wear and tear. Users are quite annoyed by this. Fat composition and preparation method. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides ...
