Embodiment 1

[0036] A damping emulsion of the present invention, which comprises the following components in parts by weight:

[0037]

[0038] Among them, the emulsifier is at least one of sodium lauryl sulfate, OP-10, and CO436, the adhesion promoter is vinyl triethoxy silane, and the pH regulator is 2-amino-2-methyl-1 -Propanol, the buffer is sodium bicarbonate, the initiator is sodium persulfate, and the flame retardant is tribromophenyl maleimide.

[0039] The preparation method of the damping emulsion of this embodiment includes the following steps:

[0040] S1. Combine 185 parts of styrene, 240 parts of butyl acrylate, 10 parts of 2-ethylhexyl acrylate, 10 parts of lauryl methacrylate, 6 parts of acrylamide, 4 parts of flame retardant, 0.5 parts of buffer and 8 parts Part of the emulsifier (containing sodium lauryl sulfate and OP-10) was dissolved in deionized water and added to the pre-emulsification kettle, stirred and mixed for 30 minutes to obtain a pre-emulsified liquid;

[0041] S2. ...

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 ...
