Construction material, use temperature range are subzero 196 degree to 450 degree, and in A grades of non-ignitable and building same service life, moisture permeable coefficient is almost
Zero.And foam glass can keep its energy-saving and environment-friendly economic benefit more prominent using discarded solid glass as raw material
Although other novel heat insulation materials emerge one after another, permanent, safety, high reliability are exhausted in low-heat with it for foam glass
The fields such as edge, tidal defense engineering, sound absorption are in occupation of increasingly consequence.
But the technology of existing foam glass board has following defect:(1)Foam glass since inside is air hole structure,
Plank is easily broken off in the handling process, influences speed of application and heat insulation effect.(2)The microcellular structure on foam glass surface can disappear
A large amount of binding material is consumed, construction efficiency is influenced, increases construction cost.
Application No. is 200910023316.1 applications for a patent for invention to disclose a kind of preparation side of high-intensity foam glass
Method, by cullet powder, CaCO3, borax, NaNO3It is added to ball milling mixing in ball grinder with refractory fibre and is uniformly placed on mould
In tool and preheated, foaming in foaming furnace, foam stabilizing are moved it into, is quickly cooled down and obtains foam glass with annealing stage.Foam glass
Middle addition refractoriness is high, the high fiber of intensity, improves the mechanical property of foam glass, but the microcellular structure on foam glass surface
Do not improved.
Application No. is 201710453447.8 Chinese invention patents to disclose a kind of overlay film foam glass board, it is characterized in that
Foam glass board upper surface is equipped with modified pitch coating, and isolated protective layer is arranged on modified pitch coating;Foam glass board following table
Face is equipped with modified pitch coating, and glass-fiber painted felt blanket layer is arranged on modified pitch coating.Glass-fiber painted felt blanket is by quartz
Sand and calcium carbonate etc. are coated in glass base fabric and obtain by a certain percentage;Fiberglass reinforced modified pitch coating is that modified pitch is equal
It is even to be coated on foam glass plate surface embedded glass fibre belt is made in bituminous coating simultaneously.Overlay film foam glass of the present invention
Although glass plate has certain buckle resistance energy, preparation method is complicated, need to cover multilayer material in foam glass plate surface,
Being firmly bonded property is to be improved.
Therefore, research and development are a kind of not only having higher mechanical strength, preferable bend resistance effect, moreover it is possible to be effectively improved
Foam glass surface microporous structure, and the foam glass with preferable moisture-proof, sound-absorbing, heat-insulating property is of great significance,
