The comparison coating 3 that thickness is 3.2mm, the average sound absorption coefficient of the comparison coating 3 is made in the comparison coating 3
More than 0.27；Flammable UL94 grades are V0 grades, good flame resistance.
In the above-described embodiments, since the sound deadening coating uses pure-acrylic emulsion to be manufactured for base-material, since pure-acrylic emulsion is complete
Portion uses acrylate as raw material, and the outdoor weathe resistance of acrylate is excellent, therefore the weatherability of pure acrylate dope is very excellent,
Especially resistance to ag(e)ing and Bao Se gloss retentions.Fire-retardant aggregate is added to be not only able to significantly improve its sound-absorbing effect, but also can
Significantly improve its flame retardant property.Carboxymethyl cellulose is thickener, also has the effect for promoting film forming.Talcum powder is filled out for enhancing
Material.Propylene glycol methyl ether acetate improves coalescence performance, is conducive to lotion and forms a film within the scope of specified temperature.
And the main component of fire-retardant aggregate be asbestos fibre, asbestos fibre have high-tensile, high flexible, chemically-resistant,
Extremely fireproof, thermal insulation are important fire prevention, insulation and thermal insulation material.Therefore the addition of fire-retardant aggregate, can significantly improve
The flame retardant property of the sound-absorbing coating.Since asbestos are the fine tubulose fiber assemblies that are arranged in parallel with each other, can split into non-
Often thin asbestos fibre, diameter can be small to less than 0.1 micron.Therefore, asbestos fibre is due to when in use, most fasciculation, though
So it is with fine pore, but its sound absorbing power is limited, only adds in powder to the sound deadening coating made of asbestos fibre,
The anti-flammability of sound deadening coating can only be improved, to its sound-absorbing effect without help.
Therefore asbestos fibre is modified using bisphenol A type epoxy resin, E44 types epoxy resin, basic magnesium carbonate,
Middle dicyandiamide is curing agent, and 2-methylimidazole is catalyst, can add curing reaction process, and silane coupling agent can improve stone
Binding force between cotton fiber and bisphenol A type epoxy resin, E44 type epoxy resin, dimethyl formyl be solvent, bisphenol-A type ring
Can be fully wrapped around by asbestos fibre after oxygen resin and E44 type epoxy resin cures, asbestos fibre is avoided further to divide, bis-phenol
A types epoxy resin and E44 types epoxy resin have adhesive strength, deformation retract rate is small, product size stability is good, hardness is high,
Flexibility is good, therefore fire-retardant aggregate obtained is unlikely to deform, and grain size stability can be good.Basic magnesium carbonate is main at 220 ~ 360 DEG C
If the crystallization water starts to decompose, after 360 DEG C, carbon dioxide, magnesia and water are started to decompose into；Therefore, at 365 ~ 370 DEG C
At a temperature of in the plate crude green body that cures, due to the presence of vapor, carbon dioxide so that containing a large amount of in plate crude green body
Micropore, but also the surface of fire-retardant aggregate and internal containing a large amount of micropores, and microcellular structure is not easily damaged, and fire-retardant aggregate grain
Diameter is small, this causes the stomata that connection of largely opening up to each other easily is formed in subsequent sound-absorbing coating, and the porosity of sound-absorbing coating is notable
Increase, the sound-absorbing effect of sound-absorbing coating significantly improve.Relative to common sound-absorbing material expanded perlite, the fire-retardant aggregate is also
With the sound-absorbing effect for improving sound-absorbing coating, and promote amplitude and be better than expanded perlite.
