High waterproof type composite water-soluble organic silicon resin coating for exhaust pipe of forklift engine and preparation method thereof

Abstract

The invention relates to the technical field of coating for exhaust pipe of engine, in particular to a high waterproof type composite water-soluble organic silicon resin coating for an exhaust pipe of a forklift engine and a preparation method thereof. The high waterproof type composite water-soluble organic silicon resin coating for the exhaust pipe of the forklift engine is a water-soluble and environmental-protection coating and is free from volatile organic solvent and pollution to the environment. Added light calcium carbonate composite active sizing agent improves the high-temperature resistance of the resin coating and enables the resin coating to have a better mechanical property, added silicone oil contained with hudrogen enables the coating to have good waterproof property, and sulfonated asphalt powder can effectively improve the film building property of the coating and prevent the composite coating from spalling and fracturing. When the coating is applied to the exhaust pipe of the engine, a good protective property is presented, a good barrier property is possessed especially to high-temperature water vapor, the coating does not spall or fracture after being used for a long time under the high-temperature condition, and the corrosion condition of the exhaust pipe is relieved effectively.

Description

technical field [0001] The invention relates to the technical field of coatings for engine exhaust pipes, in particular to a highly waterproof composite water-based silicone resin coating for forklift engine exhaust pipes 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 corrode, directly affecting the performance.

[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
