Research progress on application of spray-type damping coating

Abstract

Abstract This paper analyzes the current control requirements of mechanical vibration and noise in the fields of ships. The author briefly introduces the working principle and main classification of damping coatings, and describes the current domestic and international aspects from the types of spray-type damping coatings and spraying processes. The research progress and application of spray-type damping coatings such as asphalt damping coating, PVC based damping coating, polyurethane based damping coating, waterborne acrylic based damping coating and IPN damping coating and metal alloy coating are reviewed. The development trend and application considerations are summarized in this paper at last.
