[0003] The sliding area and bearings in the start checker need to distribute lubricating grease. Disadvantages of lubricating grease: (1) It needs to be added frequently or circulated oil supply, otherwise the normal lubrication of the machine cannot be guaranteed; (2) It has poor heat resistance and is easy to Hardening; (3) Poor water resistance, it will emulsify, become thinner and lose when it meets water, so it cannot be used in wet environment or water contact parts; (4) Poor shear resistance, under high-speed shear conditions, the consistency changes greatly, and it is easy to become thinner Loss; (5) Too much filling will increase the friction torque, deterioration, aging and softening due to heat, and lead to loss of lubricating grease; too little or insufficient filling will cause dry friction; (6) Need to stay away from high temperature heat source; (7) cannot be applied to equipment with high environmental protection requirements

Embodiment 1
[0009] The technical solution adopted in this embodiment is: a solid lubricant for a starter is composed of the following raw materials in parts by weight: 15 parts of N-methylpyrrolidone, 15 parts of methyl isobutyl ketone, 1 part of fumed silicon dioxide, silicon carbide 1 part, 1 part of graphite, 1 part of molybdenum disulfide, 0.1 part of BYK399 leveling agent, 10 parts of polyamideimide, 1 part of epoxy resin, 10 parts of isocyanate; its production method comprises the following steps: the first step, Put an appropriate amount of N-methylpyrrolidone, methyl isobutyl ketone, fumed silicon dioxide, and silicon micropowder into the mixing tank according to the metering ratio, and stir evenly; in the second step, add an appropriate amount of graphite and molybdenum disulfide according to the metering ratio Put it into the mixing tank and stir it evenly; the third step is to put the leveling agent, polyamideimide resin, epoxy resin and isocyanate into the mixing tank and mix i...
Embodiment 2
[0011] The difference between this implementation and Example 1 is that it consists of the following raw materials in parts by weight: 20 parts of N-methylpyrrolidone, 20 parts of methyl isobutyl ketone, 5 parts of fumed silica, 5 parts of silicon carbide, graphite 5 parts, 5 parts of molybdenum disulfide, 0.5 parts of BYK399 leveling agent, 25 parts of polyamideimide, 5 parts of epoxy resin, 25 parts of isocyanate.
[0012] The composition of other raw materials, production process and method of use are all the same as in Example 1.
Embodiment 3
[0014] The difference between this implementation and Example 1 is that it consists of the following raw materials in parts by weight: 25 parts of N-methylpyrrolidone, 25 parts of methyl isobutyl ketone, 10 parts of fumed silica, 10 parts of silicon carbide, graphite 10 parts, 10 parts of molybdenum disulfide, 1 part of BYK399 leveling agent, 30 parts of polyamideimide, 10 parts of epoxy resin, 30 parts of isocyanate.
[0015] The composition of other raw materials, production process and method of use are all the same as in Example 1.

Abstract
The invention relates to a solid lubrication material used for a starter and a production technology, and an application method thereof, which relate to technical field of solid lubrication. The solidlubrication material comprises the raw materials: N-methyl pyrrolidone, MIBK, a gas-phase silica, silicon carbide, graphite, molybdenum disulfide, a BYK 399 levelling agent, polyamide-imide, epoxy resin, and isocyanate; and above raw materials are taken according to a metering ratio, and then processed by a production technology of the solid lubrication material used for the starter to obtain thesolid lubrication material. By employing the above technical scheme, the solid lubrication material has high adhesiveness, pressure resistance and chronergy, an operational temperature range is widerthan that of lubrication grease, a firm film is formed, high work load and sudden workload can be bear, when the solid lubrication material is not replaced after long-term usage, and the solid lubrication material can ensure the function of lubrication, prolongs the maintenance period, reduces the consumption, and reduce the maintenance and use cost.
Description
technical field [0001] The invention relates to the technical field of solid lubrication, in particular to a solid lubricant for a starter, a production process and a use method thereof. Background technique [0002] The starter checker is an accessory on the starter. When starting the ignition, the magnetic switch is first energized, and the magnetic switch pulls the checker to form a magnetic field between the starter rotor and the coil, and the starter starts to work. [0003] The sliding area and bearings in the start checker need to distribute lubricating grease. Disadvantages of lubricating grease: (1) It needs to be added frequently or circulated oil supply, otherwise the normal lubrication of the machine cannot be guaranteed; (2) It has poor heat resistance and is easy to Hardening; (3) Poor water resistance, it will emulsify, become thinner and lose when it meets water, so it cannot be used in wet environment or water contact parts; (4) Poor shear resistance, under ...
