Description
Technical field
The present invention relates to damping slurry technical fields more particularly to a kind of automobile-used water base damping slurry and preparation method thereof.
Background technology
Internal car noise has become urgent problem to be solved for restricting rail traffic vehicles sustainable development, compartment
Air-borne sound and structure-borne sound transmission at plate are the main sources of internal car noise.Develop with the lightweight of train, aluminium alloy extrusions
Have become the material of main part of rail traffic vehicles car body floor structure, it is to improve vehicle interior sound field environment to improve floor sound insulation property
An effective way.It can not only reach good noise reduction in aluminium alloy extrusions spraying damping slurry, and will not be to train system
System performance makes a significant impact, easy to operate, it is easy to accomplish.
Damping slurry is using viscoelastic property possessed by high-molecular organic material, and the mechanical vibrational energy of sound wave is converted to heat
It can release, reduce amplitude, reduction vibration so as to reach, inhibit the purpose of noise.Aqueous damping coating has good resistance
Combustion property, high adhesion force, corrosion resistance, ageing resistance, high damping properties and it is easy for construction the advantages that, be widely used in automobile,
Train, steamer, aircraft, engineering machinery and other household appliance technical fields play the effect of sound insulation, sound absorption, damping and heat preservation.It is water base
Damping pulp is using aqueous-based polymers as crosslinked emulsions, help and compounded with ingredients such as filler, pigment, auxiliary agents, wherein filler
Species and the structure feature of filler have significant impact to the damping capacity of material, rigidity and damping temperature range.
The content of the invention
The defects of present invention is in order to make up prior art provides a kind of automobile-used water base damping slurry and preparation method thereof.
