The method for preparation of the heat preservation light material by pile mud foaming provided by the invention has the advantages of simple process, low cost, environmental pollution reduction, full use of waste materials and the like. The prepared heat preservation light material has the characteristics of good thermal insulation effect and light weight, etc.
Description
Technical field
The present invention relates to a kind of preparation method of heat preservation construction material, be specifically related to the method that heat-insulating light material is prepared in the foaming of a kind of pile foundation slurry.
Background technology
Industrial premises, resident's building, office building, the buildingss such as bridge need to drive piles when building usually, and can produce a large amount of pile foundation slurry in piling process.Pile foundation slurry, primarily of water and solid phase particles composition, has very high viscosity and concentration, long-term standing also delamination.
If pile foundation slurry is directly discharged in surrounding environment without any process, can causes serious harm, be embodied in: easily cause Soil Surrounding to harden to environment, vegetation is capped and mortality; If be directly discharged in rivers and lakes, easily cause water pollution, river channel sedimentation, impact navigation; And if pile foundation slurry is accumulated by suction pit, valuable land resources will be taken for a long time.
Therefore, for solving the problems of the technologies described above, the necessary method providing the foaming of a kind of pile foundation slurry to prepare heat-insulating light material, to overcome described defect of the prior art.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of technique simple, cost is low, can reduce environmental pollution and the method for heat-insulating light material is prepared in the pile foundation slurry foaming that can make full use of waste material.
For achieving the above object, the technical scheme that the present invention takes is: the method for heat-insulating light material is prepared in the foaming of a kind of pile foundation slurry, and it comprises following processing step: 1), in pile foundation slurry, mix whipping agent, and adds terra alba simultaneously and stir; 2) carry out drying or drying after, foaming 30 ~ 90 minutes; 3), dry or dry rear feeding in kiln and fire, final formation heat-insulating light material.
The method that heat-insulating light material is prepared in pile foundation slurry foaming of the present invention is further: in step 1), described whipping agent is specially hydrogen peroxide or aluminium powder, and it is 2:100 with the weight ratio of pile foundation slurry; The weight that described terra alba accounts for pile foundation slurry is 10 ~ 30%.
The method that heat-insulating light material is prepared in pile foundation slurry foaming of the present invention is further: step 2) in, the temperature of described oven dry is 100 ~ 150 DEG C, and the time is 15 ~ 24h.
The method that heat-insulating light material is prepared in pile foundation slurry foaming of the present invention is further: in step 3), the temperature fired in described kiln is 1000 ~ 1200 DEG C, and the firing time is 20 ~ 30h.
The method that heat-insulating light material is prepared in pile foundation slurry foaming of the present invention is further: the density of this heat-insulating light material is 500 ~ 700kg/m3, and thermal conductivity is 0.06 ~ 015.
The method that heat-insulating light material is prepared in pile foundation slurry foaming of the present invention also can be: add coal dust when adding terra alba in step 1), the weight that described coal dust accounts for pile foundation slurry is 4 ~ 8% simultaneously; And in step 4), the temperature fired in described kiln is 700 ± 50 DEG C, the firing time is 20 ~ 30h.
Compared with prior art, the present invention has following beneficial effect: it is simple that the method that heat-insulating light material is prepared in pile foundation slurry foaming of the present invention has technique, cost is low, can environmental pollution be reduced and can the plurality of advantages such as waste material be made full use of, the features such as obtained heat-insulating light material has good effect of heat insulation, lightweight.
Embodiment
The present invention is the method that heat-insulating light material is prepared in the foaming of a kind of pile foundation slurry, and it comprises following processing step:
1), in pile foundation slurry, mix whipping agent, and add terra alba simultaneously and stir; Wherein, described whipping agent is specially hydrogen peroxide or aluminium powder etc., and it is 2:100 with the weight ratio of pile foundation slurry; The weight that described terra alba accounts for pile foundation slurry is 10 ~ 30%, and this terra alba can effectively avoid the pile foundation slurry after foaming to subside;
2) carry out drying or drying after, foaming 30 ~ 90 minutes; Wherein, temperature during oven dry is 100 ~ 150 DEG C, and the time is 15 ~ 24h;
3), dry or dry rear feeding in kiln and fire, final formation heat-insulating light material; Wherein, the temperature fired in described kiln is 1000 ~ 1200 DEG C, and the firing time is that 20 ~ 30h(comprises high temperature, low temperature, cooling time); The weight of obtained warm light material every cube is 200 kilograms.
It is as follows that the present invention is that another embodiment of method of heat-insulating light material is prepared in the foaming of a kind of pile foundation slurry, and it comprises following processing step:
1), in pile foundation slurry, mix whipping agent, and add terra alba simultaneously, coal dust stirs; Wherein, described whipping agent is specially hydrogen peroxide or aluminium powder etc., and it is 2:100 with the weight ratio of pile foundation slurry; The weight that described terra alba accounts for pile foundation slurry is 10 ~ 30%, and this terra alba can effectively avoid the pile foundation slurry after foaming to subside; The weight that described coal dust accounts for pile foundation slurry is 4 ~ 8%;
2) carry out drying or drying after, foaming 30 ~ 90 minutes; Wherein, temperature during oven dry is 100 ~ 150 DEG C, and the time is 15 ~ 24h;
3), dry or dry rear feeding in kiln and fire, final formation heat-insulating light material; Wherein, the temperature fired in described kiln is 700 ± 50 DEG C, and the firing time is that 20 ~ 30h(comprises high temperature, low temperature, cooling time), this is because coal dust has higher calorific value, suitably can reduce firing temperature.
