Abstract
The invention relates to electric lubricating grease and a preparation method thereof, and in particular relates to electric lubricating grease used for a terminal in the electric locomotive and power industries and a preparation method thereof. A fatty acid soap-type thickening agent is weighed in proportion and is added into base oil to be mixed, stirring and slow heating are carried out, then the base oil is continuously added, stirring and heating are continuously carried out, and then the base oil is added, and mixing is carried out and homogenizing by virtue of a homogenizer or grinding by virtue of a grinding machine is carried out, thus base ester is obtained; and an anti-oxidation additive, an anti-corrosion additive, an anti-rust additive, a conductive additive and an anti-static additive are sequentially added into the obtained base ester and mixed; and then the mixture is homogenized by virtue of the homogenizer or ground by virtue of the grinding machine; and finally filtering and packaging are carried out to obtain the electric lubricating grease product. The lubricating grease provided by the invention has excellent conductive performance, contact condition of an electric contact is effectively improved, and antiseptic and antirust performances of the electric contact are obviously improved. The electric lubricating grease product can be widely applied to the electric contact of an electric locomotive and a power supply system.
Description
technical field [0001] The invention relates to an electric lubricating grease and a preparation method thereof, in particular to a lubricating grease used for electric locomotives and terminals in the electric power industry and a preparation method thereof. Background technique [0002] When electrical contacts are used for a long time, surface oxidation and corrosion will occur, which will affect the electrical conductivity of the contact point. The electric grease coating the contact end surface first acts as an anti-oxidant, preventing oxidative gas from entering the contact area, preventing or reducing Cu 2 O.AL 2 o 3 Wait for the formation of oxide film to avoid the increase of contact resistance; secondly, prevent the intrusion of water vapor and chemical corrosive gases, reduce electrochemical corrosion and chemical corrosion; finally, special fine conductive materials fill the fine gaps on the contact surface, improving the electrical resistance. Electrical and ...
