Problems solved by technology

However, in some special equipment fields, such as automobile engines, the outer casing temperature is about 70-110°C during normal operation, and it is required that the water-based damping coating can not only play a damping and vibration reduction effect in such a high temperature range, but also must have good performance. Heat dissipation performance, otherwise it will increase the workload of the cooling system, resulting in serious adverse consequences
At present, water-based damping coatings at home and abroad are mainly used in the normal temperature range, and there are no strict requirements for heat dissipation

The high-temperature-range water-based damping paint disclosed in the invention can be used for controlling vibration and noise of vibration basal bodies requiring high application temperature, has favorable heat dispersion property and anticorrosion property, and can well keep the coating strength within high temperature range. The method disclosed by the invention can be used for efficiently preparing the high-temperature-range water-based damping paint.

Description

technical field [0001] The invention relates to a water-based damping paint and a preparation method thereof, in particular to a water-based damping paint in a high-temperature region with good heat dissipation performance and a preparation method thereof. Background technique [0002] Traditional coatings use organic solvents as the dispersion medium, and there is a large amount of toxic and harmful gases and waste water discharged during the production process and construction application process, which not only pollutes the environment, air and water resources, but also seriously damages the health of production and construction personnel. healthy. Water-based damping paint is a green and environmentally friendly paint that uses water as the main dispersion medium, uses inorganic and organic matter as fillers, and does not contain any toxic organic solvents. [0003] Water-based damping coating has the advantages of good flame retardancy, high adhesion, corrosion resista...
