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 paint, and specifically relates to an engine damping paint. Background technique [0002] Because water-based damping coatings mainly use water as a dispersant, they have low VOC and are green and environmentally friendly, and are now gradually replacing traditional organic solvent-based damping coatings and asphalt-based damping sheets. At the same time, due to the characteristics of the coating, it can be easily coated on more complex interfaces without cutting. Therefore, it has more advantages in construction than the traditional butyl rubber damping film. Due to the disadvantages of water-based damping coatings, their wider applications are also limited. [0003] Damping paint is a new type of functional material that can absorb vibrational mechanical energy. Various mechanical equipment or transportation vehicles' engines or electromechanical equipment will produce varying degrees of vibration a...
