Nanometer titanium nitride-doped high-stability anticorrosion composite aqueous organosilicon resin coating material for forklift engine gas discharge pipe, and preparation method thereof

Abstract

The present invention relates to the technical field of engine gas discharge pipes, particularly to a nanometer titanium nitride-doped high-stability anticorrosion composite aqueous organosilicon resin coating material for a forklift engine gas discharge pipe, and a preparation method thereof. According to the present invention, the product is an aqueous environmental-protection coating material, does not contain volatile organic solvents, and does not pollute the environment; with the added nanometer titanium nitride, the expanded perlite and other raw materials, the temperature resistance of the material is increased, the oxidation rust on the metal under the high temperature condition is effectively prevented, and the mechanical property of the resin coating is improved; with the sulfonated asphalt powder, the film forming ability of the coating can be effectively improved, and the coating shedding can be prevented; and when the coating material is applied in the engine gas discharge pipe, the good protection performance is provided, the stable mechanical property is maintained after the long-term use under the high temperature condition, no peeling and cracking is generated, and the corrosion condition of the gas discharge pipe is effectively alleviated.

Description

technical field [0001] The invention relates to the technical field of coatings for engine exhaust pipes, in particular to a high-stable anti-corrosion composite water-based organic silicon resin coating for forklift engine exhaust pipes mixed with nano-titanium nitride and a preparation method thereof. Background technique [0002] Due to the characteristics of the environment in which the exhaust pipe of the forklift engine is used and its own working conditions, the protection of the exhaust pipe is particularly important. The main method of protecting the exhaust pipe is to spray paint on its surface with high temperature resistance and anti-rust effects. Currently, it is widely used The paints used are mainly organosilicon high-temperature resistant paints. However, organosilicon paints are prone to problems such as decomposition, air bubbles, and peeling off under high temperature conditions, which will cause the pipeline to lose its protective layer and oxidize and cor...

[0002] Due to the characteristics of the environment in which the exhaust pipe of the forklift engine is used and its own working conditions, the protection of the exhaust pipe is particularly important. The main method of protecting the exhaust pipe is to spray paint on its surface with high temperature resistance and anti-rust effects. Currently, it is widely used The paints used are mainly organosilicon high-temperature resistant paints. However, organosilicon paints are prone to problems such as decomposition, air bubbles, and peeling off under high temperature conditions, which will cause the pipeline to lose its protective layer and oxidize and corrode, directly affecting the performance. Therefore, there is an urgent need for traditional Improve the performance of silicone heat-resistant paint to make it more suitable for the working environment of the exhaust pipe to achieve a good protective effect
