Embodiment 1
[0032] In parts by mass: 50 parts of epoxy resin, 5 parts of polytetrafluoroethylene, 27.5 parts of polyamide, 3 parts of molybdenum disulfide, 5 parts of sodium lauryl sulfate, 28 parts of acetone, 28 parts of xylene and 28 parts parts n-butanol. The mass ratio of the polytetrafluoroethylene to the epoxy resin is 1:10.
[0033] Prepare the anti-stick coating as follows:
[0034] (a) Add polytetrafluoroethylene powder and molybdenum disulfide chelated to the mixing tank, stir evenly, and the stirring speed is 100rpm / min to obtain the mixture;
[0035] (b) Add the mixed solution of xylene and n-butanol into the mixing tank, then add the mixture of step (a) into the mixing tank while stirring, the stirring speed is 300-400rpm / min;
[0036] (c) Sodium lauryl sulfate is added in the mixing tank, continue to stir, stirring speed 300-400rpm / min, stir evenly;
[0037] (d) epoxy resin is dissolved in solvent acetone, obtains solution;
[0038] (e) adding the solution in step (d) a...
