[0024] A high-performance exhaust pipe coating and a preparation method thereof, comprising the steps of:
[0025] S1. Weigh a certain amount of 20-25 parts of silicone resin, 15-25 parts of iron oxide compound, 8-12 parts of carbon, 10-18 parts of manganese, 3-8 parts of sulfur, 6-15 parts of phthalic acid, 2 to 4 parts of copper, 3 to 8 parts of mica powder, 3 to 7 parts of talc powder, additives and solvents for spare use, firstly add carbon, manganese, sulfur and copper to the melting furnace for high-temperature heating and melting to obtain mixed metal liquid,
[0026] S2. First, add silicone resin, iron oxide compound, mica powder and talc powder into the furnace containing the mixed metal liquid to heat and stir to obtain the mixture. After standing still, perform stirring operation until it is evenly stirred for high temperature resistant coating mixture;
[0027] S3, passing the high temperature resistant coating mixture obtained in step S2 through inspection, filli...
