Abstract

The invention discloses a high-temperature-resistant exhaust pipe coating and a preparation method thereof. The coating is prepared from raw materials in parts by weight as follows: 20-30 parts of aluminum powder, 11-22 parts of silica powder, 10-18 parts of manganese, 3-8 parts of carbon, 6-15 parts of zinc oxide powder, 2-4 parts of copper, 3-8 parts of mica powder, 3-7 parts of talc and a solvent. The mica powder and the talc are added to the aluminum powder, the silica powder, the zinc oxide powder and the copper, the high-temperature resistance of the coating is enhanced, the porous state caused by thermal decomposition in the preparation process is improved due to addition of the mica powder and carbon black, the coating is more stable, the added solvent has characteristics of high-temperature resistance and high corrosion resistance, meanwhile, the stability of a coating material can be improved, and the coating is safe and environment-friendly. The coating has multiple functions of curing, toughening, diluting, prolonging the pot life and the like, is used as a curing agent and enables a cured product to have higher heat resistance, flame retardance and ablation resistance and excellent electrical properties.
