Description

A kind of environmental-friendly walling lagging material

Technical field

The present invention relates to wall heat insulation material technical field, particularly relate to a kind of environmental-friendly walling lagging 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

The object of the invention is exactly the defect in order to make up prior art, provides a kind of environmental-friendly walling lagging material.

The present invention is achieved by the following technical solutions:

A kind of environmental-friendly walling lagging material, is made up of the raw material of following weight part: shell powder 6-8, polyvinyl alcohol 4-5, bismuthyl chloride 2-3, magnesium hydroxide 3-4, mud 210-250, Vac/E polymer dispersion powder 4-5, polyacrylamide 2.5-3, polygorskite powder 12-14, sodium lauryl sulphate 1.7-2.4, alpha-semi water plaster stone 120-130, cement 7.5-9, flyash 5-5.6, gac 4-5, sawdust powder 6-8, sapphire whisker 4-5, methyl-silicone oil 2-3, diatomite 8-9, alum 4-5, white mineral oil 1-2, water are appropriate.

A kind of environmental-friendly walling lagging material, be made up of following concrete steps:

(1) gac and diatomite are added in mud stir, under natural condition, mix 5-6 days, then by mud thermal pretreatment, temperature is 170-175 ° of C, time is 30-35min, be added to after naturally cooling in anaerobic pond, under anaerobic, temperature is 35-40 ° of C, pH value remains on 7.0-7.4 anaerobic digestion reaction 10-13 days, carry out drying treatment after reaction terminates, under 140-150 ° of C, process 6-7h, after naturally cooling, milled 300-400 mesh sieve is for subsequent use;

(2) water of polyvinyl alcohol by 10-13 times amount is diluted, add magnesium hydroxide ultrasonic disperse even, add mud powder mixing and stirring prepared by step (1) again, then shell powder and polygorskite powder mixture surface is coated on, be placed in baking oven to dry, be finally in the Vac/E polymer dispersion powder solution of 15-18% in concentration by impregnation mixture, evaporation removing moisture post-drying is for subsequent use;

(3) product prepared by step (2), alpha-semi water plaster stone powder mixing and stirring, stir according to water paste ratio 1:1.2-1:1.4 and form gypsum slurries, again sodium lauryl sulphate is mixed at room temperature mechanical stirring with the water of 4-5 times amount and form the slurries that foam, then the slurries that will foam mix with gypsum slurries, Keep agitation also adds other surplus materialss such as flyash, cement, finally slurry is poured in mould, be put in room ventilated place naturally shaping.

Advantage of the present invention is: the present invention adopts gac and diatomite to carry out deodorizing to mud, Anaerobic Digestion greatly reduces organic content in mud afterwards, the effect of disinfection is played in pyroprocessing, treated mud is coated on filling surface, dispersible latax with Vac/E again and do WATER REPELLENT, improve intensity greatly, moistureproof, waterproof, insulation, the effect of the aspect such as heat insulation, the present invention adopts material based on alpha-semi water plaster stone, there is very high intensity, crushing resistance, water tolerance and easy casting, whipping agent is added in gypsum slurries, being uniformly mixed of short period of time gets final product casting, without the need to special casting equipment, technique is simple, with short production cycle, efficiency is high, also have a large amount of tiny in Foamed Gypsum material, uniform bubble, not only play good insulation effect, can also the mechanical property of reinforcement material, environmental-friendly walling lagging material of the present invention, the phenomenon efficiently solve cracking of wall surface, coming off, has the effect of insulation, waterproof, high strength, and cost is low, pollution-free.
