Description
Technical field
The present invention relates to a kind of novel material of construction, be specifically related to a kind of lightweight inorganic fireproof heat preservation plate material.
Background technology
By the relevant regulations that the Fire-Fighting Bureau under the Ministry of Public Security issues, in the residential housing of building, A level insulating layer of external wall must be installed, otherwise cannot by checking and accepting.National standardization management committee formally issues GB8624-2012 " material of construction and product burns grading performance ", and on October 1st, 2013 implements.This standard instead of primary standard GB8624-2006 " material of construction and product burns grading performance ".Mainly have modified division and the grading criteria of burning behavior class; Add the classification system for fire performance of specific end use goods; Have modified the content such as Additional Information and burning behavior class mark.The issuing and implementation of this standard to improving material of construction and the goods fire safety in practical engineering application, reduce disaster hidden-trouble, specification enterprise produces and the supervision and management of being convenient to superintendent office will play a significant role.The enforcement of this standard, has promoted the application of the inorganic fireproofing heat-insulation board with A level fire resistance further.
Lagging material on the market mainly contains following several: inorganic kervit microbead insulated sand slurry, pearlite heat-insulation plate, styrofoam (EPS), extruded sheet (XPS) and cement board etc.Styrofoam and extruded sheet are all the hard foams prepared by different foam process and extrusion process for main raw material(s) with organism such as polystyrene resins, and other different materials heat insulating coefficient is low relatively, high insulating effect; But due to the production technique of XPS plate, thermostability is poor, the protection mortar outside its heat-insulation system and coating hollowing easy to crack, easy; Another organic heat-insulating sheet material fire performance is poor, and do not reach the Residential fire A level compulsory standard of country at present, therefore domestic a lot of province has prohibitted the use organic heat preservation plate material.Pearlite heat-insulation plate belongs to inorganic heat insulation material, and its main advantage is that flame retardant properties is good, can reach A level fire-protection standard; Ageing-resistant, can with the building same life-span, but limit its main factor used and be that its water-intake rate is high, and it is relatively high to compare organic materials (EPS, XPS etc.) its thermal conductivity.The general pore of foaming insulation board is on the market comparatively large, and wayward, water-intake rate is high, causes wall hollow drum and efflorescence.
Study the development trend that novel inorganic heat preservation fire-retardant material becomes the industry.
