taking the following raw materials in parts by weight for standby: 70 parts of polytetrafluoroethylene, 65 parts of polypropylene, 50 parts of polycarbonate, 40 parts of polyethylene terephthalate, 25 parts of tricresyl phosphate, 20 parts of triethanolamine oleate, 10 parts of potassium oleate, 15 parts of cyclohexanone, 15 parts of dimethyl adipate, 15 parts of diphenylethanone and 10 parts of hydroxyethylated fatty amine;

s1, preparing an antifouling coating preparation liquid: uniformly mixing polytetrafluoroethylene, polypropylene and polycarbonate, heating to 220 ℃, uniformly stirring, and then preserving heat for 10min to obtain an antifouling coating pre-preparation liquid;

s2, preparing an antifouling coating solution; adding polyethylene terephthalate, tricresyl phosphate, triethanolamine oleate, potassium oleate, cyclohexanone, dimethyl adipate, diphenylethanone and hydroxyethylated fatty amine into the antifouling coating pre-preparation liquid, stirring uniformly, heating to 240 ℃, and keeping the temperature for 10min to obtain an antifouling coating solution;

s3, spraying: spraying the inner wall surface of the fixed cylinder 13 by using an automatic spraying machine;

s4, drying: the fixed cylinder 13 obtained in the step S3 is dried in an oven at 50 ℃ for 2 hours.

The antifouling coating of the inner wall of the fixed cylinder 13 can avoid the problem that the inner wall of the fixed cylinder 13 is polluted by liquid medicine to cause difficulty in cleaning.
