Abstract

The invention provides a water-borne sound-insulating damping coating for a ship. According to the water-borne sound-insulating damping coating for the ship, water-borne mixed emulsion is used as film forming matter, inorganic filter is used as main filler, and coating aids are added. The water-borne sound-insulating damping coating for the ship mainly comprises, by weight, 30 parts to 55 parts of water-borne styrene-acrylic emulsion which is of an interpenetrated network structure, 30 parts to 60 parts of the inorganic filler and 20 parts to 40 parts of fire retardants. The water-borne sound-insulating damping coating for the ship is prepared by preparing the water-borne mixed emulsion, adding the filler and the aids, and conducting paint mixing, white mica powder is used as functional damping filler, and blanc fixe is used as functional sound-insulating filler. The water-borne sound-insulating damping coating for the ship has the advantages that the recombination loss factor is high, and the sound insulation coefficient is high; the performance of being rapidly dried at normal temperature can be achieved; the adhesive force to a steel plate is high; the fire retardant property is high, and the shipment use requirement is met; the steel plate is free of rust; the workability is high; no hazardous substances exist, and environmental friendliness is achieved.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a water-based sound-insulating and damping coating for ships. The coating has good sound-insulating and damping properties at room temperature, and is mainly suitable for those who need to perform vibration- and noise-reducing treatment on the berthing deck. technology field. Background technique [0002] According to the requirements of the International Maritime Organization (IMO) for sound insulation ships, the development and application of deck damping coatings has become a necessary condition for the development of deck coverings to meet the sound insulation requirements between residential spaces. The rules specify the noise level limits for different places, including the weighted sound insulation index of 35 from the living room to the living room, and the weighted sound insulation index of restaurants, entertainment rooms, public places and from the entertai...
