Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of damping insulating foam concrete material and preparation method thereof.
Background technology
Foamed concrete introduces appropriate micro-bubble by physics or chemical process in grout or sand-cement slurry, the blown-out concrete of a large amount of pore is contained in a kind of inside of sclerosis, there is lightweight, insulation, sound insulation, resistance toly to freeze, the function such as shock-absorbing, be normally used for energy-saving heat preserving, noise control, the engineering applications such as Highrise buildings, shock-absorbing buffering and Anomalistic space filling.At present, the insulation of foamed concrete, the function such as heat insulation are widely applied.But along with the raising of people's living standard, also higher to the Functional Requirement of material of construction, as surge chamber humidity, create more comfortable environment, then require that foamed concrete has good humidity conditioning function.
For improving foamed concrete damping ability, existing scholar has carried out research, as Chinese invention patent 201410100140.6 discloses a kind of air-conditioning-type foamed concrete material and preparation method thereof, clay is adopted to improve foamed concrete damping ability as humextant, but do not provide damping effect assessment, article " research of novel gypsum base foamed concrete humidity " adopts gypsum to prepare foamed concrete as gelling material, utilize the damping characteristic of gypsum to improve the damping ability of foamed concrete, but gypsum damping ability own is more weak, adjustment humidity range is not enough.Therefore, invention one had both had good heat insulation function, had again the foamed concrete material continuing damping characteristic preferably simultaneously, will have important theory and engineering significance.
Summary of the invention
The object of the present invention is to provide a kind of damping insulating foam concrete and preparation method thereof, this damping insulating foam concrete has lightweight, insulation, feature that adjustable wet is good.
To achieve these goals, technical scheme of the present invention is:
A kind of damping insulating foam concrete material, is characterized in that it is respectively by weight by cement, flyash, humidity adjusting material, stablizer, whipping agent and water: cement 35-45 part, flyash 15-25 part, humidity adjusting material 5 ~ 10 parts, stablizer 1 ~ 2 part, whipping agent 3 ~ 5 parts, 24 ~ 32 parts, water form.
By such scheme, described cement is ordinary Portland cement and aluminosulfate cement, wherein: the weight percent of each component is: ordinary Portland cement 0-20%, aluminosulfate cement 80%-100%.
By such scheme, described ordinary Portland cement is preferably the ordinary Portland cement that strength grade is not less than 42.5 grades.
By such scheme, described humidity adjusting material is zeolite powder.
By such scheme, the particle diameter of described zeolite powder is 100-200 order.
By such scheme, described stablizer is dodecyl sulphate calcium.
By such scheme, described whipping agent is hydrogen peroxide, concentration 30wt%-50wt%.
The preparation method of above-mentioned damping insulating foam concrete material comprises the steps:
1) humidity adjusting material is immersed in whipping agent extremely saturated, obtain the pre-treatment humidity adjusting material of preabsorption whipping agent;
2) cement, flyash, stablizer are mixed, then add water and be stirred into even slurry, after add pre-treatment humidity adjusting material and stir, leave standstill foaming, to be foamedly to complete, the demoulding after hardening of cement.
Zeolite surface is coarse, is vesicular structure, has stronger adsorptive power and carrying capability, material not only can be made to be adsorbed on zeolite surface equably, and can be adsorbed onto in hole and passage.Further, it can by whipping agent preadsorption in humidity adjusting material as humidity adjusting material, make whipping agent slow releasing form pore around humidity adjusting material particle, and make humidity adjusting material be in pore center, improve damping effect, coordinate the use of stablizer simultaneously, can bubble stability be increased, make the pore of formation evenly, be also more conducive to the raising of damping insulating foam concrete strength.In addition, the present invention consider whipping agent hydrogen peroxide in the basic conditions stability can be deteriorated, cause outgassing rate to strengthen, reduce slurry system basicity by composite aluminosulfate cement especially thus, meanwhile, flyash is also conducive to system basicity to be reduced, and controls hydrogen peroxide gas forming rate with this.
Beneficial effect of the present invention:
The damping insulating foam concrete technology index that the present invention obtains meets design requirement, and has good damping heat-insulating property.Key technical index is as follows:
1) ultimate compression strength >0.9MPa;
2) thermal conductivity <0.08W/mk;
3) adjustable wet: moisture uptake >80g/m
2; Moisture releasing amount >70g/m
2;
Heat preservation humidity conditioning foamed concrete material preparation technology of the present invention is simple, and pore structure is easy to control.
