Abstract
The present invention relates to a kind of damping insulating foam concrete material, it is characterised in that：It is respectively by weight by cement, flyash, humidity adjusting material, stabilizer, foaming agent and water：24 ~ 32 parts of 35 45 parts of cement, 15 25 parts of flyash, 5~10 parts of humidity adjusting material, 1~2 part of stabilizer, 3 ~ 5 parts of foaming agent, water compositions.Damping insulating foam concrete technology index produced by the present invention meets design requirement, has good damping heat-insulating property.
Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of damping insulating foam concrete material and its preparation
Method.
Background technology
Foam concrete is by either physically or chemically introducing appropriate micro-bubble in cement mortar or cement mortar, firmly
Change the blown-out concrete that a large amount of stomatas are contained in a kind of inside formed, there is the work(such as lightweight, insulation, sound insulation, resistance to jelly, shock-absorbing
Can, it is normally used for the engineering applications such as energy-saving heat preserving, Noise measarement, skyscraper, shock-absorbing buffering and Anomalistic space filling.Mesh
Before, the function such as be incubated, be heat-insulated of foam concrete is widely applied.But as the improvement of people's living standards, to building
The Functional Requirement of material is also higher, such as adjusts indoor humidity, creates more comfortable environment, then requires that foam concrete has
Good humidity conditioning function.
To improve foam concrete damping ability, existing scholar has carried out research, such as Chinese invention patent
201410100140.6 disclose a kind of air-conditioning-type foamed concrete material and preparation method thereof, using clay as conditioning agent come
Foam concrete damping ability is improved, but does not provide damping effect assessment, article《Novel gypsum base foam concrete humidity
Research》Foam concrete is prepared as binder materials using gypsum, foam concrete is improved using the damping characteristic of gypsum
Damping ability, but gypsum damping ability itself is weaker, adjustment humidity range deficiency.Therefore, invention is a kind of had both had good protect
Temperature function, while there is the foamed concrete material for preferably continuing damping characteristic again, it will be anticipated with important theory with engineering
Justice.
The content of the invention
It is an object of the invention to provide a kind of damping insulating foam concrete and preparation method thereof, the damping insulating foam
Concrete has the characteristics of lightweight, insulation, good adjustable wet.
To achieve these goals, the technical scheme is that：
A kind of damping insulating foam concrete material, it is characterised in that it by cement, flyash, humidity adjusting material, stabilizer,
Foaming agent and water are respectively by weight：Cement 35-45 parts, flyash 15-25 parts, 5~10 parts of humidity adjusting material, stabilizer 1~2
24~32 parts of part, 3~5 parts of foaming agent, water compositions.
By such scheme, described cement is Portland cement and sulphate aluminium cement, wherein：The weight of each component
Percentage is：Portland cement 0-20%, sulphate aluminium cement 80%-100%.
By such scheme, described Portland cement is preferably the normal silicate that strength grade is not less than 42.5 grades
Cement.
By such scheme, described humidity adjusting material is zeolite powder.
By such scheme, the particle diameter of the zeolite powder is 100-200 mesh.
By such scheme, described stabilizer is dodecyl sulphate calcium.
By such scheme, described foaming agent is hydrogen peroxide, concentration 30wt%-50wt%.
The preparation method of above-mentioned damping insulating foam concrete material comprises the following steps：
1) humidity adjusting material is immersed in foaming agent to saturation, obtains the pretreatment humidity adjusting material of pre-absorption foaming agent；
2) cement, flyash, stabilizer are well mixed, add water and be stirred into even slurry, it is rear to add pre- place
Reason humidity adjusting material stirs, stand foaming, to be foamed to complete, be stripped after hardening of cement.
Zeolite surface is coarse, is loose structure, has stronger adsorption capacity and carrying capability, can not only make material uniform
Ground is adsorbed in zeolite surface, and can be adsorbed onto in hole and passage.Further, it can be pre- by foaming agent as humidity adjusting material
It is adsorbed in humidity adjusting material, foaming agent is slowly discharged around humidity adjusting material particle and form stomata, and makes at humidity adjusting material
In stomata center, damping effect is improved, while coordinates the use of stabilizer, bubble stability can be increased, make the stomata to be formed more
Uniformly, the also more conducively raising of damping insulating foam concrete strength.In addition, the present invention considers foaming agent hydrogen peroxide in alkalescence
Condition stability inferior can be deteriorated, and cause outgassing rate to increase, and thus reduce slurry body especially through compounding sulphate aluminium cement
It is basicity, meanwhile, flyash is also beneficial to the reduction of system basicity, and hydrogen peroxide gas forming rate is controlled with this.
Beneficial effects of the present invention：
Damping insulating foam concrete technology index produced by the present invention meets design requirement, and there is good damping to be incubated
Performance.Key technical index is as follows：
1) compression strength>0.9MPa；
2) thermal conductivity factor<0.08W/m·k；
3) adjustable wet：Hygroscopic capacity>80g/m2；Moisture releasing amount>70g/m2；
The heat preservation humidity conditioning foamed concrete material preparation technology of the present invention is simple, and pore structure is easily controllable.
