Abstract

The present invention discloses an automobile exhaust pipe composite temperature resistance coating, which comprises a component A and a component B, wherein the component A comprises the following components, by weight, 90-110 parts of an inorganic silicate film forming substance, 30-50 parts of flaky zinc sheets, 3-6 parts of flaky aluminum sheets, and 1-2 parts of a silane coupling agent, and the component B comprises the following components, by weight, 80-100 parts of an organosilicon resin, and 20-40 parts of flaky aluminum sheets. The automobile exhaust pipe composite temperature resistance coating of the present invention has the following advantages that: after an automobile exhaust pipe is coated with the composite temperature resistance coating of the present invention, technical requirements of high temperature resistance and corrosion resistance of the exhaust pipe can be solved so as to improve a service life of the exhaust pipe and reduce cost.

Description

technical field [0001] The invention relates to a coating, in particular to a composite temperature-resistant coating for an automobile exhaust pipe. Background technique [0002] The automobile exhaust pipe is installed in the exhaust pipe between the engine exhaust manifold 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 muffler system role. It is mainly used in light vehicles, mini-cars and passenger cars. Existing automobile exhaust pipes are coated with protective paint, but this protective paint only has high temperature resistance, and it will be rapidly oxidized and corroded when high temperature is generated after use. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of high temperature resistance, corrosion-resistant automobile exhaust pipe composite temperature...
