Damping emulsion, preparation method thereof, low-VOC, low-odor and high-flame-retardance water-based damping coating and preparation method of coating

Abstract

The invention provides a damping emulsion, a preparation method thereof, a low-VOC, low-odor and high-flame-retardance water-based damping coating prepared from the damping emulsion, and a preparationmethod of the coating. The damping emulsion comprises styrene, butyl acrylate, 2-ethylhexyl acrylate, lauryl methacrylate, acrylamide, an emulsifier, a flame retardant, a buffer agent, an initiator,an adhesion promoter, a pH regulator and deionized water. The water-based damping coating prepared from the damping emulsion comprises the damping emulsion, deionized water, the pH regulator, an antifoaming agent, a dispersant, mica powder, hollow beads, a coloring agent, a bactericide, ammonium polyphosphate, a flash etchant, a substrate wetting agent, a thixotropic agent and a thickener. The damping emulsion has the advantages of high flame retardance, high loss factor, low film forming temperature, interpenetrating network structure and excellent damping performance, and the obtained damping coating has the characteristics of damping, cracking resistance and flame retardation.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a damping emulsion and a preparation method thereof, and also relates to a low-VOC, low-odor, high-flame retardant water-based damping coating and a preparation method thereof. Background technique [0002] With the continuous development of economy and society, people's requirements for travel comfort continue to increase, and higher requirements are placed on the vibration and noise reduction effects of vehicles. At present, many domestic vehicles, urban rails, high-speed trains, large railway passenger cars and other vehicles have begun to spray damping paint to reduce vibration and noise. [0003] Because oil-based paint has high VOC, large smell, environmental pollution, inflammable and explosive, easy to spontaneously ignite and other safety hazards, oil-based paint is generally classified as a hazardous chemical in China, and its transportation, storage and use must ...

AI Technical Summary

Problems solved by technology

[0003] Because oil-based paints have safety hazards such as high VOC, strong odor, environmental pollution, flammability, explosion, and spontaneous combustion, oil-based paints are generally listed as hazardous chemicals in China, and their transportation, storage and use must be strictly in accordance with the national hazardous chemicals Regulations carried out
