Technical field
The present invention relates to a kind of insulation board and preparation process more particularly to a kind of Novel fire-resistance heat-insulation plate and preparation processes.
Background technique
With the development of urban construction, as the exterior-wall heat insulation of residential architecture and public building it is not up to standard and caused by safety
Potential problem is more and more prominent, and with regard to External Wall fire prevention measure, more stringent requirements are proposed for this, is such as more than or equal to 27 in residential housing
When rice is not higher than 100 meters, it is desirable that add fire-blocking belt to add fire window using A grades of fireproof and heat-insulating materials or B1 grades of thermal insulation materials.By
In current residential housing layer height substantially at 33 layers and hereinafter, in view of fire window price and effect after, substantially respectively
Real estate company has all selected combustibility for A grades of thermal insulation material.Entire thermal insulation material market is made a general survey of, flameproof effect is most at present
Well, it is most suitable for doing the only rock wool of external-wall heat-insulation material.Once supply falls short of demand for the supply of material of rock wool material as a result,.But rock wool conduct
External-wall heat-insulation material is fallen off, itself bulk density is pasted onto greatly as water absorption rate height easily leads to absorb water after breakage there is also shortcomings
Safety is poor after exterior wall, and production, work progress have an injury to operator, and rock wool production process needs to heat rock to molten
Change, needs to consume a large amount of thermal energy etc..
In view of problem above, thermal insulation material manufacturer is in the research for being dedicated to new A grade fireproof and heat-insulating material.By
Effort carries out fire-retardant cladding to thermoplastic granular polystyrene by using special fire retardant, changes into it heat cured compound
Insulation board has been studied.But existing thermosetting property composite insulation boards are because of the difference of formula, bulk density, thermal coefficient and rock wool
Plate is compared to prominent not enough, if the bulk density of thermosetting property composite insulation boards and thermally conductive can be reduced by rationally adjusting formula and dosage
Coefficient, thermosetting property composite insulation boards will capture following heat preservation construction material market.
