Problems solved by technology

The water-based damping coating has a high composite loss factor and excellent damping performance in low temperature environments, but has the disadvantages of poor flame retardancy and long drying time
Marine damping materials not only require good damping performance, but also require high flame retardancy, good workability and fast drying speed, so the existing environmentally friendly damping coatings cannot meet the requirements of marine materials

Abstract

The invention provides a marine water-based damping coating and a preparation method thereof. A water-based styrene-acrylic emulsion with an interpenetrating polymer network structure is used as a film forming matter, mica powder with a laminated structure is used as a filler and coating additives are added. The marine water-based damping coating comprises the following main components in parts by weight: 40-65 parts of water-based mixed emulsion, 35-60 parts of filler and 20-40 parts of flame retardants. The marine water-based damping coating is prepared by mixing water-based emulsions, adding the filler and the additives and mixing the coating. The marine water-based damping coating disclosed by the invention has construction performances, high complex loss factor, strong adhesion to steel plates and good flame retardance, can be quickly dried under normal temperature, can ensure the steel plates not to rust after being applied and is environmentally friendly.

Description

technical field [0001] The invention relates to a water-based marine damping paint and a preparation method thereof. Background technique [0002] With the development of science and technology, the problem of noise pollution from berthing has attracted widespread attention, and a series of laws, regulations, and rules have been promulgated at home and abroad to increase the intensity of the regulation of noise pollution. The control of noise is mainly achieved through the control of noise sources, transmission channels and the protection of receivers. Among them, in terms of controlling noise sources and transmission channels, damping coatings have been widely promoted and applied due to their convenient construction, low cost, and good damping performance, especially environmentally friendly damping coatings. [0003] Environmentally friendly damping coatings have both the energy loss characteristics of some viscous liquids in a certain state and the energy storage charac...
