Embodiment 1
[0029] The bonding solid lubricating coating of the present embodiment is made up of the following components in percentage by weight: 8% epoxy resin, 8% polyamide, 10% polytetrafluoroethylene, 10% molybdenum disulfide, 1 % surfactant, the balance is solvent; wherein the solvent is a mixture of n-butanol and xylene, and the volume ratio of n-butanol and xylene is 3:7.
[0030] The preparation method of the bonded solid lubricating coating of the present embodiment, the specific operation steps are as follows:
[0031] 1) The solvent prepared in proportion is divided into two parts on average, epoxy resin is added to one part of the solvent to obtain an epoxy resin emulsion; polyamide is added to another part of the solvent to obtain a polyamide emulsion;
[0032] 2) Weigh polytetrafluoroethylene and molybdenum disulfide powders, put them into a ball mill jar and grind them to make them evenly mixed to obtain mixed powder;
[0033] 3) adding the mixed powder obtained in step 2...
