Abstract

The invention discloses a high-performance coating for an exhaust pipe and a preparation method thereof. The coating includes the following raw materials, by weight, 20-25 parts of silicone resin, 15-25 parts of a ferric oxide composite, 8-12 parts of carbon, 10-18 parts of manganese, 3-8 parts of sulfur, 6-15 parts of phthalic acid, 2-4 parts of copper, 3-8 parts of mica powder and 3-7 parts of talcum powder, and additives and solvents. IN the invention, the silicone resin and the ferric oxide composite are mixed with a mixture of the carbon, manganese, sulfur and copper, and then the mica powder and the talcum powder are added to improve the high-temperature resistance of the coating. The porous status due to thermal decomposition during the process is improved due to the mica powder and the talcum powder, so that the coating is more stable. The added solvent is high-temperature-resistant and has strong anti-corrosion property. High-temperature-curing silicone resin is employed and has stable chemical properties, strong hydrophobicity and is free of toxicity and irritation on skin, so that the coating is safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of exhaust pipes, in particular to a high-performance exhaust pipe coating and a preparation method thereof. Background technique [0002] High-temperature-resistant coatings are widely used in many fields such as automobiles, construction, metallurgy, and manufacturing, as well as daily necessities such as gas stoves, water heaters, and electric heaters, and are closely related to people's daily life and industrial production. With its unique properties, high-temperature-resistant coatings enable the functions of many products and equipment to be fully utilized, and become an indispensable new variety in the coatings industry. [0003] The automobile exhaust pipe is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, facilitating installation and prolonging the life of the exhaust...
