Abstract
The invention discloses a composite inorganic foaming agent taking an inorganic compound (hydrogen peroxide) as a main body, and an application of the composite inorganic foaming agent. The inorganic cement foaming agent comprises the following components by mass percentage, 90-95% of hydrogen peroxide, 5-10% of ammonium carbonate, and an assistant accounting for 0.05-0.5% of total mass percentage of hydrogen peroxide and ammonium carbonate. The application of the inorganic cement foaming agent comprises the steps of adding the inorganic cement foaming agent accounting for 2-5% of the mass percentage of cement to concrete cement grout for stirring, allowing the concrete to be foamed rapidly after 5-10s, allowing the volume of the concrete to be expanded to be full filled in a mold frame within 10min, and allowing the concrete to be solidified automatically after 3-5h to form a foamed concrete block. No foaming machine is required, and the foaming agent is directly added to the cement grout for stirring. The foaming agent has the advantages of good foaming effect, low cost and safety and convenience in use, and is suitable for mass production and worth for extensive popularization and application.
Description
Technical field
The present invention relates to industry and the foam concrete block manufacturing that covil construction hand walls and roofs and heat insulating use, be specifically related to a kind of inorganic type cement blowing agent and application thereof.
Background technology
Along with the urban house construction to energy-conservation mandatory code requirement, the foam concrete block that various industry and covil construction hand walls and roofs and heat insulating use is used widely.One of key of cement foamed technology bubble concrete segment manufacturing is cement blowing agent.
The used whipping agent of foamed concrete foams to propose technical requirements for concrete.It pays attention to the stability of foam especially except the macrofoam generative capacity, the exquisiteness of foam, the adaptability of the gelling material such as foam and cement etc.The narrow sense whipping agent that can satisfy this requirement also is few, and most of whipping agents can not be used for the foamed concrete actual production.Therefore, foam concrete foamer must be a few surface promoting agent or the surfactant that meets above-mentioned technical requirements.
At present, mostly adopt the foamed concrete organic blowing agent on the market.The problem that the foamed concrete organic blowing agent exists is: (1) gas forming amount is little, general only is the 15%-30% of inorganic foamed whipping agent, level of residue is large, comprising water and volatile matter, sometimes frowziness and surperficial bloom: the decomposition thermal value of (2) foaming is large, is difficult to remove, especially in the large situation of product wall thickness degree, can make inner plastics overheated and decompose performance; (3) whipping agent nearly all is inflammable substance, and decomposition temperature is low, stores and use equal care should be used to.
Summary of the invention
Technical problem to be solved by this invention provides a kind of inorganic type cement blowing agent, has foam performance characteristics excellent, with low cost.
For solving the problems of the technologies described above, the invention provides a kind of inorganic type cement blowing agent, it is characterized in that, comprise that following quality is than component: 90%～95% hydrogen peroxide, 5%～10% volatile salt.
Preferably, described inorganic type cement blowing agent also comprises auxiliary agent, and described auxiliary agent quality is the 0.05%-0.5% of described hydrogen peroxide and volatile salt quality sum, and described auxiliary component comprises water glass, as the stablizer of hydrogen peroxide.
Preferred, comprise also in the described auxiliary agent that accounting for described auxiliary agent mass ratio is no more than 10% Sodium Silicofluoride, Sodium Silicofluoride is as the peptizer of water glass.
Inorganic type cement blowing agent of the present invention, its basic fundamental performance perameter is:
1, foaming density is 70～90g/L,
2, gas release is 150～260cc/g,
2, surely the bubble time is 1～2 hour,
3, piling height is 150～300mm,
4, partly the time of disappearing is 0.5～1 hour,
5, pH value is 8～9.
Being applied as of inorganic type cement blowing agent provided by the invention: will account for cement quality and join in the concrete cement slurries than 2%～5% described inorganic type cement blowing agent, stir, concrete foams rapidly after 5～10 seconds, and in 10 minutes, volume of concrete is expand into to be full of the mould frame, and do not subside, flawless; Solidify voluntarily after 3～5 hours and generate foam concrete block; The foam concrete block demoulding, piling, natural curing; Reach desirable use state after 8～14 days, be used for construction and installation and use.
Adopt the feel of the foamed heat insulating wallboard of inorganic type cement blowing agent provided by the invention production to have thick and heavy sense, viscoelastic good toughness.And safe, nonpoisonous and tasteless, insulation, sound insulation, fire resistance are better than industry forces standard.
Beneficial effect: inorganic type cement blowing agent of the present invention is a kind of composite inorganic whipping agent take the mineral compound hydrogen peroxide as main body.Adopt this composite inorganic whipping agent to be used for to use foaming machine when cement foamed, directly add to stir in the cement grout and get final product.It is fast to bubble, and gas release is large, uniform in foaming; Foam cement solidifies voluntarily, natural curing, manpower-free's maintenance.Therefore, have foaming effect advantage good, with low cost, safe and convenient to use, be suitable for scale operation, should vigorously promote the use.
