Fire spreading is rapid, and is produced with a large amount of poison gases and flue gas, and exceptional hardship is brought to rescue work of extinguishing fire, causes casualties
And property loss.The shortcomings of simultaneously also there is easily aging, poor dimensional stability in such insulation material.Protected compared to organic foam plastic
Adiabator, inorganic heat insulation material has that fire line is good, deformation coefficient is small, ageing resistace is strong, steady performance, so will
Foam cement insulation material is applied in wall thermal insulating, with extensive popularizing application prospect.Cement board be at present gradually
Rise a kind of external-wall heat-insulation material, it have it is non-aging, completely with the building same life-span, unit weight is light, thermal conductivity factor is low, resistance to
The fiery limit more than 3 hours, the advantages of will not produce toxic gas under high temperature or fire condition, but the shortcoming of foam cement version
It is also obvious that be exactly poor mechanical property, intensity is relatively low, fragility is larger, it is very easy to fracture, damaged, to transporting and constructed
Journey brings very big inconvenience.
The content of the invention
In view of this, it is an object of the invention to provide a kind of new modified foaming cement plate, with fire resisting, the longevity is used
Life is long, thermal conductivity factor is small, it is environmentally friendly the advantages of while, can overcome that its fragility is big, the problem of cracky again.

Part double (2,2,6,6,-tetramethyl -4- piperidyl) sebacate, 1 part of ultra-violet absorber；
Further, the sulfonated acetone formaldehyde polycondensate is obtained by the following method：Sodium sulfite and water are mixed
50 DEG C are warming up to after being slowly added dropwise acetone at being afterwards 50 DEG C in temperature, 1h is incubated, is slowly added dropwise at being again then 70 DEG C in temperature
90 DEG C are warming up to after formaldehyde, 4h is incubated；
Further, the sulfurous acid, formaldehyde, the mol ratio of acetone are：N (sodium sulfite):N (formaldehyde):N (acetone)=
0.8:2.65:1；
Further, the multiple copolymer is polycarboxylate multiple copolymer；
Further, the foam stabilizer is in ethylenediamine tetra-acetic acid, diethyl triamine pentaacetic acid, N-hydroxyethyl-ethylenediamine triacetic acid
One or more mixtures；
Further, the coupling agent is the mixture of titanate coupling agent and silane coupler；
Further, the ultra-violet absorber be salicylate, benzophenone, BTA in one or more
Mixture；
Further, the alkali proof fiber is polyphenylene sulfide fibre, p-aramid fiber, meta-aramid, polyimides, polyphenylene sulfide
It is ether, poly- to one or more mixtures in penylene benzo-dioxazole fiber.
Beneficial effects of the present invention：Modified foaming cement plate of the invention, thermal and insulating performance is good, product dry density 150-
200kg/m3, thermal conductivity factor at 0.05-0.06W/ (m*K), with good heat preservation and energy conservation effects；Fire protecting performance is good, fire resisting pole
Limit is more than 3h, A grades of fire-protection standard is can reach, so that with good fire resistance；Sound insulation value is good, can greatly reduce noise shadow
Ring；Excellent in durability, with anti-high and low-temp performance, the characteristics of corrosion-resistant, ultraviolet radiation resisting, good weatherability, dry density is
