Abstract

The invention relates to medium-temperature high-performance water-based damping coating material and a preparation method of the medium-temperature high-performance water-based damping coating material. The coating material is made from binding base material, functional filling material, auxiliary agent and the like. The preparation method adopts a low-speed mixing, dispersion and three-roll grinding technology, thereby effectively avoiding cross linked deterioration of ternary polymer emulsion in the binding base material under high temperature because of high-speed mixing and dispersion. The coating material is added with the ternary polymer emulsion, addition agent and the functional filling material, wherein the ternary polymer emulsion belongs to rubber emulsion that is beneficial to improve the damping capacity and the drying of coating films, and the functional filling material has the functions of damping vibration, reducing noises, retarding flame and the like. The coating material can form a network structure through cross linked solidification under low-temperature baking of about 60 degrees, thereby obviously increasing the damping recombination loss factor, the flame-retardant heat-insulation performance and the sound-absorbing noise-reducing property. The water-based damping coating material is widely applied to railway vehicles, has the advantages of high damping recombination loss factor, small specific weight, strong adhesive force, good flame-retardant performance, low toxicity level and easy construction, and is not easy to crack in thick coatings.

Description

technical field [0001] The invention relates to a coating, in particular to a medium-temperature high-performance water-based damping coating with the functions of vibration reduction, noise reduction, flame retardancy and low toxicity, and a preparation method thereof. Background technique [0002] At present, there are many types of damping coatings at home and abroad, but from the solvent of the coatings, there are mainly two types: solvent-based and water-based. Most of the former contain organic solvents and asphalt, which are highly toxic, highly volatile, pollute the environment, and have poor workability, so they are rarely used now. The latter damping coating uses water as a solvent, has low toxicity, low odor, low cost, easy construction, and environmental protection, and is the first choice for damping coatings for urban rail vehicles. [0003] my country has developed and produced damping coatings since the 1960s, and has formed a relatively mature development a...
