Description
Technical field
The utility model relates to a kind of fire prevention and fills sheet material, is specifically related to a kind of fire prevention foam concrete door panel.
Background technology
Along with the requirement of building a resource-conserving society of China's proposition and the in succession appearance of national energy-saving consumption reduction policy, the inorganic door panel material of energy-saving fire proof type certainly will will become the from now on developing direction of type gate core material.The main material of making in the market inorganic fire-proof door core plate has the glass bead of magnesite, rock cotton board, haydite warming plate, pearlite heat-insulation plate.Although low, the easy production shaping of magnesite foaming doors central layer cost, fire prevention, waterproof, through national fire-proof construction material quality examination Spot detection, performance indications but are better than traditional fire proofing material (alumina silicate, rock wool), but magnesite product itself exists distortion, returns halogen, degradation disadvantage under the hardness, and iron sheet there is heavy corrosion, reduce the application life of door, can't eradicate.Glass bead: coefficient of thermal conductivity is less than 0.085, advantage: fire prevention, and fire-retardant, overcome the shortcomings such as expanded perlite water absorption rate Da Yi efflorescence; Shortcoming: intensity is relatively low, and water absorption rate is higher, and heat insulation effect is general.The rock beam plate: coefficient of thermal conductivity 0.041～0.045, advantage: fire prevention, fire-retardant; Shortcoming: hygroscopicity is large, and heat insulation effect is poor, and contains the noxious materials such as formaldehyde, phenol.Haydite warming plate: coefficient of thermal conductivity: 0.08～0.10, advantage: fire prevention, do not fire, do not absorb water, easy construction is used durable; The Costco Wholesale of shortcoming material own is high.Perlite heat-insulating mortar: coefficient of thermal conductivity 0.07～0.09, advantage: fireproof performance is good, and is high temperature resistant; Shortcoming: heat insulation effect is poor, and water imbibition is high.
And common foam cement can be brought into play its good technical advantage at aspects such as light filling layer (as doing door panel etc.), exterior wall heat-preserving system, energy-conservation composite hollow building blocks.But owing to containing a large amount of CABs in the foam concrete, raw material is take powder and fine grained as main, thereby shows higher water absorption rate in performance, had a strong impact on its production and use; And the increase of the porosity that produces along with introducing foam of the intensity of foam concrete and reducing, introduce foam more, porosity is larger, unit weight is less, the performance of its lightweight, insulation, sound insulation is just more obvious, but the intensity fall is just larger, so the characteristic of foam concrete is take strength decreased as cost; Easily produce bleeding, segregation, layering, bubbling even the mould that collapses when in addition, the regular-type foam concrete grout is body formed.
Generally speaking, there are the shortcomings such as low strength, drying shrinkage is large, water absorption rate is high in the foam concrete of using at present, as common foam cement being applied to the making of door panel, then needs it is significantly improved.
Summary of the invention
