Description

A kind of wall thermal insulating scrubbing fire retardant material

Technical field

The present invention relates to wall heat insulation material technical field, particularly relate to a kind of wall thermal insulating scrubbing fire retardant material.

Background technology

Along with the national economy that China day by day increases, and urban population continuing to increase in recent years, China is more and more higher for the processing efficiency of municipal effluent, causes the output of the by product-mud produced in sewage treatment process constantly to increase.Containing a large amount of soluble flocks in the mud produced in sewage treatment process, organic substance also containing large quantity of moisture, kind complexity, simultaneously also containing the objectionable impurities such as various heavy toxic substance and pathogenic bacteria, if stacked its any landfill, do not processed, not only can cause severe contamination for environment, also have ignored the use value that these mud have simultaneously, cause the waste to resource.Traditional method for sludge treatment, the not only resource of at substantial, and can pollute surrounding enviroment, through the mud of the mode such as physics, biological chemistry process, effectively can reduce its poisonous and hazardous material, and processed after mud also there is the function such as heat-insulation and heat-preservation, sound absorption, be a kind of excellent functional construction material.Therefore but the recycling of mud is one of sludge treatment the road of supervention exhibition.In recent years, development at full speed is obtained to the recycling of mud, wherein topmost Land use systems, exactly mud is applied in material of construction, if develop a kind of lagging material containing mud on this basis, so these unmanageable mud just obtain effective utilization, are a kind of effective means that recycling sludge utilizes, also have found a kind of new environment protecting thermal insulating material simultaneously, improve the environmental protection and energy saving of material of construction.

Application number is in 200810171725.1 " sludge foaming lightweight concrete that method for sludge treatment and the method are produced and purposes " patent, also be with undressed mud and unslaked lime stirring reaction, form sludge hydrated lime, again by itself and cement, water and whipping agent are mixed to get foaming lightweight concrete, there is a lot of purposes, the performance of each side is all better than normal concrete, but in sludge handling process, waterproof and organism process are not carried out to it, have the health of people's health and affect greatly, because mud has water-absorbent, the external moisture of easy absorption, time one is long, safety coefficient can be reduced, critical people's security of the lives and property.The present invention is by certain physics, chemical mode process; reach nontoxic; the objects such as heat insulating, thermal conductivity are lower; make it as good lagging material; also have good sound-proof sound-absorbing effect simultaneously; give full play to the advantage on sludge quality, while utilization of waste material, taken into account environment protection, really realize the green hope turned waste into wealth.

Summary of the invention
