But above-mentioned inflaming retarding sponge has the following disadvantages：Although fire retardant diphenylphosphoric acid is with the addition of in inflaming retarding sponge
Ester, but it is heated after easy softening transform, once being ignited, easily cause the diffusion of flame, flame retardant effect is bad.
The content of the invention
It is an object of the invention to provide a kind of flame-retardant sponge, has the good effect of fire resistance.
The present invention above-mentioned technical purpose technical scheme is that：A kind of flame-retardant sponge, by weight
Number meter, flame-retardant sponge raw material is interior to include following components, PPG 90-110 parts；Toluene di-isocyanate(TDI) 45-65 parts；Water
3-5 parts；Foaming agent 1-5 parts；Modified silicon oil 1-3 parts；Stannous octoate 0.1-10 parts；Fire retardant 1-35 parts；Wrapped in the fire retardant
Include silicon-based mesoporous material.
By using above-mentioned technical proposal, PPG abbreviation polyethers, toluene di-isocyanate(TDI) is water white transparency to light
The primary raw material of yellow liquid, PPG and toluene di-isocyanate(TDI) as flame-retardant sponge.Modified silicon oil is also fire-retardant sea
One of raw material in silk floss, modified silicon oil is that the part methyl group in methyl-silicone oil is replaced with some groups, to improve silicone oil
Performance.After addition of water, PPG, toluene di-isocyanate(TDI), modified silicon oil form sponge after foaming.
Fire retardant is added in flame-retardant sponge, fire retardant selects silicon-based mesoporous material, according to it is international purely and applied chemistry
The regulation of federation (IUPAC), mesoporous material refer to a polyporous materials of the aperture between 2-50nm, and mesoporous material has high ratio
The pore passage structure of surface area, rule.Silicon-based mesoporous material is dispersed in flame-retardant sponge, and the macromolecule in flame-retardant sponge is embedded in silicon
In pore passage structure in based mesoporous material, as physical point of attachment.Flame-retardant sponge is in heated or burning, silicon-based mesoporous material pair

Or original shape is kept during burning, it is unlikely to deform so that flame spread.Secondly, silicon-based mesoporous material possesses high-low temperature resistant, essence
It is fire-retardant, non-ignitable silica ashes are generated during burning, cause the flame-retardant sponge self-extinguishment of burning.
Therefore, include silicon-based mesoporous material in the fire retardant in flame-retardant sponge, improve the heat decomposition temperature of flame-retardant sponge, together
When cause burning flame-retardant sponge be unlikely to deform, avoid flame-retardant sponge from spreading, silicon-based mesoporous material burning when generate titanium dioxide
Silicon ash cinder, cause flame-retardant sponge self-extinguishment, flame-retardant sponge excellent fireproof performance, good flame retardation effect.
The further setting of the present invention is：Count in parts by weight, the stannous octoate number is 0.15-3 parts.
By using above-mentioned technical proposal, stannous octoate is a kind of catalyst, plays and urges in the foaming of flame-retardant sponge raw material
Change acts on,.
The further setting of the present invention is：Count in parts by weight, polymer polyol is also included in the flame-retardant sponge raw material
Alcohol 10-40 parts.
By using above-mentioned technical proposal, polymer polyatomic alcohol is a kind of polyalcohol containing organic filler, as raw material
One of be added in flame-retardant sponge, flame-retardant sponge is possessed preferable resilience.
The further setting of the present invention is：The modified silicon oil is epoxy modified polysiloxane.
By using above-mentioned technical proposal, epoxy modified polysiloxane is to form polymethyl siloxane and the grafting of epoxy radicals alkane
A kind of organosilicon material, there is resistant to elevated temperatures characteristic.
The further setting of the present invention is：Count in parts by weight, the modified silicon oil number is 1-2 parts.
By using above-mentioned technical proposal, modified silicon oil number is 1-2 parts.
The further setting of the present invention is：Include magnesium hydroxide in the fire retardant.
By using above-mentioned technical proposal, magnesium hydroxide is excellent fire retardant, is discharged when being thermally decomposed and largely combines water,
Amount of heat is absorbed, reduces the temperature of flame-retardant sponge, further results in that the flame-retardant sponge self-extinguishment of burning, the moisture of release can also be made
For smoke suppressant, suppress flue gas during burning.
The further setting of the present invention is：Also include CNT in the fire retardant.
By using above-mentioned technical proposal, also including CNT in fire retardant, CNT is dispersed in flame-retardant sponge,
Fire-retardant effect can be played, while the macromolecular chain in flame-retardant sponge is entered in CNT, can improve the heat of flame-retardant sponge
Decomposition temperature, also cause flame-retardant sponge to keep original shape in burning, slow down the diffusion of flame.
The further setting of the present invention is：Include basalt fibre in the fire retardant.
By using above-mentioned technical proposal, basalt fibre is the fiber being prepared after basalt building stones melt, and is had
Excellent flame-retardant performance, high temperature resistant, possesses permanent fire retardant, while fire resistance fibre fire resistance is improved, basalt
Fiber, which is dispersed in when in flame-retardant sponge, to be embedded into the duct of silicon-based mesoporous material, is further enhanced flame-retardant sponge and is protected again under high temperature
Hold the performance of shape.
