Description
Technical field
The present invention relates to a kind of chemical building material technical fields, refer in particular to a kind of chemical blowing foam concrete foam stabilizing
Reinforcing agent.
Background technology
Chemical blowing foam concrete be by chemical foaming agent be added to by cement-based gelling material, admixture, additive,
In slurry made of water, through being mixed, pouring, it is quiet stop paying out bubble, the porous insulation material that maintenance forms.Chemical blowing is to pass through
Chemical foaming agent occurs chemical reaction and generates gas and foam in the slurry.Compared to physical blowing foam concrete, chemistry hair
The foam stability of bubble foam concrete is poor, abscess is coarse, aperture is uneven, in irregular shape, percent opening is high, and foam stabilizer
Selection can improve chemical blowing foam concrete pore structure well, improve production yield rate.
At present, foam stabilizer mainly has macromolecular substances (polyacrylamide, polyvinyl alcohol, albumen, polypeptide, starch, cellulose
Deng), silicones polyethers type of latex type, nonionic surfactant, aliphatic category etc..Wherein, macromolecular substances are complicated for operation, foaming
It measures low；Silicones polyethers type of latex type foam stabilizing effect is apparent, but synthesising different structure body is more, it is difficult to control；Nonionic surfactant is steady
It is general to steep effect, and by-product and impurity are more；Aliphatic category is not soluble in water, is not easy to stir evenly.The foam stabilizing effect of foam stabilizer with
Foaming system and foaming agent have much relations.Common chemical blowing foam concrete foamer is hydrogen peroxide, main in bubble
For oxygen, foam is different with air foam.
Chemical blowing foam concrete is porous light-weight material, and intensity is low, and demoulding time is long, and water absorption rate is high, and is cutting
It cracks with easy during use, thus its application and popularization are subject to certain restrictions.
Invention content
The technical problem to be solved in the present invention is to provide a kind of chemical blowing foam concrete foam stabilizing reinforcing agent.
The invention is realized in this way：A kind of chemical blowing foam concrete foam stabilizing reinforcing agent, including following parts by weight
Several each components：
The advantage of the invention is that：
1) foam concrete available for production high-strength light, product water absorption rate is low, service life is long；
2) extend the foam stabilization time, improve foam concrete pore structure, improve yield rate；
3) shorten demoulding time, improve early strength, and not easy to crack.
Specific embodiment
A kind of chemical blowing foam concrete foam stabilizing reinforcing agent includes each component of following parts by weight：
The foam stabilizing reinforcing agent using water-based calcium stearate as primary raw material, add it is a certain amount of promote solidifying early strength agent calcium chloride,
Organosilicon moisture repellent, polyoxyethylene economization agent and water-retaining agent composition, water-retaining agent is hydroxypropyl methyl cellulose；It only need to be by more than
Raw material is added in container by a certain percentage, is stirred continuously, and is fully dissolved, you can is used.
Embodiment one
Weigh the water of 80g, the water-based calcium stearate of 25g, the calcium chloride of 5g, the organosilicon moisture repellent of 0.1g, 1g polyoxy second
The hydroxypropyl methyl cellulose of alkenes economization agent and 0.1g are stirred continuously in container, are fully dissolved, you can obtain chemical blowing
Foam concrete foam stabilizing reinforcing agent produces every cubic metre of foam concrete, adds in above-mentioned foam stabilizing reinforcing agent 1000g uniform stirrings
.With reference to JG/T 266《Foam concrete》The dry density for measuring finished product is 268kg, compression strength 1.05MPa, water suction etc.
Grade is W5.
Embodiment two
Weigh the water of 80g, the water-based calcium stearate of 30g, the calcium chloride of 10g, the organosilicon moisture repellent of 0.2g, 2g polyoxy second
The hydroxypropyl methyl cellulose of alkenes economization agent and 0.5g are stirred continuously in container, are fully dissolved, you can obtain chemical blowing
Foam concrete foam stabilizing reinforcing agent.Every cubic metre of foam concrete is produced, adds in above-mentioned foam stabilizing reinforcing agent 1000g uniform stirrings
.With reference to JG/T 266《Foam concrete》The dry density for measuring finished product is 266kg, compression strength 0.97MPa, water suction etc.
Grade is W5.
Embodiment three
Weigh the water of 80g, the water-based calcium stearate of 34g, the calcium chloride of 7g, the organosilicon moisture repellent of 0.5g, 1g polyoxy second
The hydroxypropyl methyl cellulose of alkenes economization agent and 0.1g are stirred continuously in container, are fully dissolved, you can obtain chemical blowing
Foam concrete foam stabilizing reinforcing agent.Every cubic metre of foam concrete is produced, adds in above-mentioned foam stabilizing reinforcing agent 1000g uniform stirrings
.With reference to JG/T 266《Foam concrete》The dry density for measuring finished product is 261kg, compression strength 0.90MPa, water suction etc.
Grade is W5.
The present invention has the following advantages：
1) present invention uses water-based calcium stearate as the main component of foam stabilizing reinforcing agent, overcomes calcium stearate powder foam stabilizing
The hydrophobicity of agent mixes with slurry and is more easy to uniformly mix, and shortens mixing time, and the oxygen foam system that chemical blowing generates
Adaptability is more good, enhances foam stabilizing effect, and abscess is more uniformly distributed, and improves yield rate；
2) using calcium chloride early strength coagulant, the presetting period of slurry can be shortened, greatly improve early strength, 6 hours
It is interior to demould, improve production efficiency；
3) it can effectively solve the disadvantage that the water absorption rate of foam concrete is high using organosilicon moisture repellent；
4) foam concrete early strength can be reduced using polyoxyethylene economization agent and increases too fast caused contraction, reduced
Later stage cracking phenomena extends the service life of foam concrete；
5) it can be reduced in production process using hydroxypropyl methyl cellulose water-retaining agent and be done caused by strong wind, hot weather etc.
Dry contraction fissure.
Although specific embodiments of the present invention have been described above, those familiar with the art should manage
Solution, our described specific embodiments are merely exemplary rather than for the restriction to the scope of the present invention, are familiar with this
The equivalent modification and variation that the technical staff in field is made in the spirit according to the present invention, should all cover the present invention's
In scope of the claimed protection.
