Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of preparation method of foamed concrete thermal-insulating material.
Background technology
In recent years, China's vast north of china in winter heating districts cities and towns increase heating house floor area of building newly every year on average can up to 1 × 10
8m
2.If under equal conditions, all new buildings are all adopted energy-saving design, these newly-increased heating building area energy-saving indexs are controlled within 50%, be then often only the heating coal that this part increases building newly and just can reduce 1500kt.In addition, decrease the consumption of coal, the consequent is just the reduction of the discharge of the obnoxious flavoures such as the sulfurous gas given off in burning of coal process, the discharge of flue dust, the discharge etc. of lime-ash.As can be seen here; the energy conservation standard developed the high-efficiency insulated lagging material of applicable China's national situation, vigorously promote the use energy saving building, conscientiously implement China, is extremely important for saving heating energy consumption, protection of the environment, growing continuously and fast of maintenance Chinese national economy.
Novel environment-friendly energy saving building material is different from common material of construction, it not only will have, and quality is light, the mechanical property of the high excellence of intensity, and will have as thermal properties such as the necessary heat insulating of lagging material, sound insulation, antidetonations, thus a comfortable living environment can be provided for occupant.In recent years, ultralight foamed concrete was more and more applied in building operation as a kind of heat insulating material.In the preparation process of ultralight foamed concrete, very strict to the performance requriements of gelling material, not only require that the gelling material adopted has higher early strength, faster time of coagulation, also will possess early strength and develop very fast, later strength comparatively high.Based on above reason, in actual production, preparing ultralight foamed concrete great majority is using the special cement such as aluminosulfate cement, ferro-aluminate cement as gelling material.But prepare foamed concrete with special cement and there are problems: first, large quantifier elimination shows both at home and abroad, and the weather resistance of special cement, concrete product is far away not as good as Portland cement, concrete product.Especially, when special cement, concrete product are applied to buildings outside, the weather resistance of goods will sharply decline; Secondly, compared with Portland cement, concrete, the resource of the special cements such as sulplo-aluminate is relatively deficient, and price comparatively Portland cement wants high a lot; These all seriously hinder the ultralight foamed concrete of special cement further developing as lagging material.Therefore, research and develop with Portland cement is that major gelled material, economic novel ultra-light foamed concrete that is durable, excellent performance are imperative.
