Problems solved by technology

Traditional oil-based damping coatings often use the method of adding fillers to increase the specific gravity of the coating to improve the damping effect of the damping coating. However, the interaction between various substances inside the damping material and the selection of fillers are relatively simple, and the oil-based damping coatings currently used Some of the paint varieties are two-component polyurethanes. In the actual construction process, two scraping coatings are required. Compared with the spraying method, it is more complicated. It has higher requirements on the surface of the coating substrate, and it is difficult to take care of curved surfaces or corners.

Description

technical field [0001] The invention provides a quick-drying, high-damping oil-based damping paint and a preparation method thereof, which can be mainly used for vibrating substrates, and can make the obtained polymer material have better damping and shock-absorbing effects. Background technique [0002] All kinds of mechanical equipment will generate different degrees of vibration and noise during operation and work. Damping vibration and noise reduction technology is one of the effective methods to control vibration and noise. Damping material is a new type of functional material that can absorb vibrational mechanical energy. 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. [0003] As we all know, water-based coatings have the advantages of low pollution, environmental protection, etc., and are relatively safe to store. However, the long drying tim...
