Abstract

The invention provides damping paint for an engine. The damping paint comprises raw materials in parts by weight as follows: 290-310 parts of plasticizing acrylic emulsion, 35-45 parts of antimony (III) oxide, 35-45 parts of melamine, 18-22 parts of active magnesium hydroxide and 138-162 parts of functional filler. The damping paint for the engine has good flame retardance, noise isolation property and resistance to acid, alkali and salt spray, and meets application demands of the engine.

Description

technical field [0001] The invention belongs to the technical field of damping coatings, in particular to an engine damping coating. Background technique [0002] Water-based damping coatings mainly use water as a dispersant, have low VOC, and are environmentally friendly, and are gradually replacing traditional organic solvent-based damping coatings and asphalt-type damping sheets. At the same time, due to the characteristics of its coating, it can be easily coated on more complex interfaces without cutting. Therefore, it has more advantages in construction than the traditional butyl rubber type damping film. Due to some disadvantages of water-based damping coatings, their wider application is also limited. [0003] Damping coating is a new type of functional material capable of absorbing vibrational mechanical energy. The engines or electromechanical equipment of various mechanical equipment or transport vehicles will produce different degrees of vibration and noise whe...
