Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a cold-resistant and water-resistant polymer damping coating. Background technique [0002] Polymer damping coating is a special coating with shock absorption, sound insulation and certain sealing performance made of high molecular polymer as the base material resin. Because of its convenient construction, it can better reflect its superiority especially for the surface with complex structure. At present, it has been widely used in the shock absorption and noise reduction of aircraft, ships, vehicles and various machinery. With the improvement of people's living standards and the emphasis on environmental factors, people have higher and higher requirements for sound insulation and noise reduction coatings. The damping performance, cold resistance and water resistance of existing damping coatings cannot meet the requirements of society. Therefore, how to develop a cold-resistant...
