Abstract

The invention provides a quick-drying water-based damping paint which is made by mixing an emulsion A and an emulsion B. The emulsion A takes a water-based emulsion as a main agent, and then sheet-shaped mica powder, an inorganic filler and assistants are added, wherein the water-based emulsion is one or more of pure acrylic emulsion, polyvinyl alcohol and water-based asphalt, the inorganic filler is one or more of light calcium carbonate, bentonite and silica fume powder, and the assistants comprise a flame retardant, a dispersant, a defoamer, a mildew preventive and a thickener; and the emulsion B comprises a demulsifier, a drier and water. The quick-drying water-based damping paint of the invention can effectively increase the drying speed of the water-based damping material and has a higher damping loss factor; and when being applied to vibration substrates, the quick-drying water-based damping paint has the advantages of quick drying, favorable substrate attachment property, highstrength, favorable weather resistance and prominent damping effect.

Description

technical field [0001] The invention relates to a water-based damping coating and a preparation method thereof, in particular to a quick-drying water-based damping coating and a preparation method thereof, belonging to the technical field of chemical coatings. Background technique [0002] Damping material is a new type of functional material that can absorb vibrational mechanical energy. All kinds of mechanical equipment will generate different degrees of vibration and noise during operation and work. Damping shock absorption and noise reduction technology is one of the methods to effectively control vibration and noise. Due to its unique viscoelasticity, polymer materials can convert mechanical vibration energy into heat energy and dissipate it, so they are widely used as damping coatings. At present, there are many types of damping coatings at home and abroad, but from the solvent of the coatings, there are mainly two types: solvent-based and water-based. Most of the fo...
