Abstract
The utility model relates to an air duct sheet material, in particular to a foam glass composite air duct sheet material, which is an interlayer structure, and comprises a metal surface layer, a fireproof or anti-corrosion surface layer and a foam glass layer, wherein the metal surface layer is used as the outer surface of an air duct, the fireproof or anti-corrosion surface layer is used as the inner surface of the air duct, the foam glass layer is used as a core material, and the three are closely adhered together through two adhesion layers. Compared with the prior art, because foam glass which has low volume weight, small thermal conductivity coefficient, no moisture permeation, no water absorption, no burning, no mildewing, no mouse biting, high mechanical strength and easy processing and the like is used as the core material, the composite air duct sheet material can meet various demands of a traditional composite air duct sheet material, also can completely meet the building fireproof demands in personal highly dense fields which are sustainably developed super high-rise buildings, underground engineering, such as metro and the like and railway stations and the like, and represents the development tendency of the air duct sheet material.
Description
Technical field
The utility model relates to a kind of air duct board, is meant a kind of foam glass composite air duct board especially.
Background technology
Foam glass be a kind of be primary raw material with glass, mix an amount of blowing agent, add by high temperature tunnel kiln and make after thermal bake-out and annealing cooling processing are handled, have the novel inorganic heat-insulating material of uniform independent closed gap structure.Because it has kept the chemical stability of unorganic glass fully, unit weight is low, thermal conductivity factor is little, not wet, do not absorb water, do not burn, do not go mouldy, be not subjected to rat eaten thoroughly, mechanical strength is high easily processes but have, ability all chemical erosion except that hydrogen fluoride.Not only itself is nontoxic for foam glass, stable chemical performance, and the good heat-proof quality that can undergo no deterioration in the wide temperature range of high temperature at ultralow temperature, and itself play protection against the tide, fire prevention, corrosion-resistant effect again.When it uses under severe rugged environments such as low-temperature deep, underground, open-air, inflammable, easy tide and chemical erosion, not only safe and reliable, and also durable in use, be described as " the permanent heat-barrier material that need not change ".
And present widely used composite air duct board, core mainly adopts phenol formaldehyde foam, though do not burn during naked light, but because be organic material, when fire takes place, the high temperature that other flammable construction material forms when burning will impel phenol formaldehyde foam to decompose, and produce certain pernicious gas, influence the personnel escape; Moreover for personnel's highly dense places such as underground engineering, railway station such as the high-rise building of sustainable development, subways, traditional composite air duct board has been not suitable for using, and especially can not satisfy the fire protection requirement of relevant architectural design.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of foam glass composite air duct board that adopts foam glass as core is provided, and can satisfy various Building Fire Protection requirements.
The utility model adopts following technical scheme: a kind of foam glass composite air duct board, this air duct board is a sandwich structure, it comprise as airduct outside metal faced, as the fire prevention of airduct inner face or corrosion protection surface layer, as the foam glass layer of core, closely be sticked together by two tack coats between the three.
The thickness of described foam glass layer is 10-100mm.
The density of described foam glass layer is 100-250kg/m
3
Described metal faced thickness is 0.01-5mm.
Described metal faced be aluminium foil, aluminium sheet, color steel, galvanized sheet, galvanized iron sheet, corrosion resistant plate, stainless iron plate or plastic-steel plate.
The thickness of described fire prevention or corrosion protection surface layer is 0.01-5mm.
Described fire prevention or corrosion protection surface layer are flexible face materials such as aluminium foil, aluminium-foil paper, aluminium foil fiber cloth or sandwich reinforced aluminium foil.
Described fire prevention or corrosion protection surface layer are metal faced materials such as aluminium foil, aluminium sheet, color steel, galvanized sheet, galvanized iron sheet, corrosion resistant plate, stainless iron plate or plastic-steel plate.
Described tack coat is flame-retarding adhesives such as phenolic foam glue, flame retardant polyurethane foamed glue, fire-retardant neoprene or fire-retardant butyl rubber.
By above-mentioned to description of the present utility model as can be known, compared with prior art, it is low that a kind of foam glass composite air duct board of the present utility model owing to adopt has unit weight, thermal conductivity factor is little, not wet thoroughly, do not absorb water, do not burn, do not go mouldy, be not subjected to rat eaten, but the foam glass of advantages such as the high easily processing of mechanical strength is as core, make composite air duct board of the present utility model can satisfy every requirement of traditional composite air duct board, can satisfy the high-rise building of sustainable development again fully, underground engineerings such as subway, the development trend of composite air duct board has been represented in the Building Fire Protection requirement in personnel's highly dense places such as railway station; Compare as traditional air duct board of core with materials such as adopting phenol formaldehyde foam, have plurality of advantages such as environmental protection, long service life, security performance are good, have vast market prospect.
Description of drawings
Fig. 1 is the structural representation of a kind of foam glass composite air duct board of the present utility model.
The specific embodiment
Below the utility model will be further described by the specific embodiment.
A kind of foam glass composite air duct board of the present utility model, it is a sandwich structure, it comprise as airduct outside metal faced 20, as the fire prevention of airduct inner face or corrosion protection surface layer 30, as the foam glass layer 10 of core, closely be sticked together by two tack coats 40 between the three.
A kind of foam glass composite air duct board of the present utility model during fabrication, at first the foam glass with bulk cuts into sheet material, thickness is 10-100mm, again the sheet material of small dimension is spliced into the wide continuous sheet of 1200mm after the finishing; With metal faced 20 and fire prevention of roll type or corrosion protection surface layer 30 at the uniform velocity blowing and roller coat tack coat 40, behind the heating, drying, directly with to carry the foam glass sheet material 10 of coming in to paste continuously compound, it is molded to continue warm-up mill again; With sheet material cut after the deburring the foam glass composite air duct board finished product.
According to the needs of different occasions, metal faced 20 and fire prevention or corrosion protection surface layer 30 can select the thickness of 0.01-5mm not wait.
