Background technique
With the development of Building technology, building tends to high stratification and enlargement.Therefore mitigate the structure of skyscraper certainly
Weight, the materials for wall for developing light thermal-insulation have become highly important project.With the continuous improvement to building energy conservation requirement, gently
The materials for wall dosage of matter high-durability will be continuously increased.A series of freeze thawing due to occurring in air entrained concrete engineering in recent years
Degradation phenomena more causes the wretched insufficiency of light wall material.Thus the light wall material of development of new is very must
It wants.With economic continuous development, people's lives level is also being continuously improved, they to the environment locating for itself it is also proposed that
Requirement that is higher, updating, these all give the development of new building energy conservation type materials for wall and application extension wide space.
Foamed brick compression strength is greater than 0.5MPa, does not crack, long service life, foamed brick also useful different raw material system
At.Foam water adobe is to be condensed using foam little particle with cement mixing, has lightweight, heat preservation, sound insulation, fireproof high-quality
Performance, and due to having used the reason of minor diameter to greatly reduce cost, it is the ideal of non-load bearing wall.Steam pressure foam is mixed
Solidifying cob brick is mainly production raw material by cement, slag powders, river sand, is foamed after mixing and stirring through pressure air, air is mixed in pressure
Enter mixing slurry inner mold at the concrete of microbubble structure pours mold forming, is made through processes such as steam pressure reactions, is a kind of ring
It protects, energy saving, stable material quality novel wall material.The building of materials for wall is done using steam pressure foam concrete brick, building up makes
With after 2 years through examining, it is superior in quality, meet country to construction quality, the standard requirements such as sound insulation, energy conservation, fire prevention.It also is non-hold
Weight wall brick.The conventional foam brick problem bad there is also compression strength and durability at present, therefore also need to grind it
Study carefully.
Summary of the invention
The technical problems to be solved by the invention: for current foamed brick, there is also compression strength and durability are bad
Problem, the present invention provides a kind of preparation methods of foamed brick.
In order to solve the above technical problems, the present invention is using technical solution as described below:
A kind of preparation method of foamed brick, the preparation method include the following steps:

It is put into container and is stirred than 7~9:2, stand；
(2) after standing, mixture in collection vessel, by container mixture, ammonium acrylate 7:1 in mass ratio~
3 are put into reactor, are protected using gaseous mixture, preheating；
(3) after preheating, the auxiliary agent of ammonium acrylate quality 1~3% is added, heats up, keeps the temperature, cooling, discharging is collected in discharging
Dried object is collected in object, spray drying；
(4) according to parts by weight, 50~60 parts of water, 30~35 parts of portland cements, 16~19 parts of dried objects, 5~7 parts of surfaces are taken
Activating agent, 2~8 parts of quartz sands, are stirred, and are put into extrusion forming in mold, calcine to get foamed brick.
Waste liquid is papermaking wastewater in the step (1), 5~7:4~8 mix pickling waste waters by volume.
In the step (1) waste residue be aluminium ash, steel slag 4~8:5~7 in mass ratio mill to get.
Additive is polyacrylamide in the step (1), sodium humate 4:1~2 in mass ratio mix.
Gaseous mixture is that 3:2~5 mix hydrogen in molar ratio with oxygen in the step (2).
Auxiliary agent is N, N- carbonyl dimidazoles in the step (3).
In the step (4) surfactant be fatty alcohol polyoxyethylene ether, it is any one in lauryl amine propionate
Kind.
The present invention is compared with other methods, and advantageous effects are:
The present invention effectively reduces production cost, by waste liquid to the work of waste residue by acting on raw material using waste liquid and waste residue
With the metallics in waste residue can be made to be formed with ion and existed, while can be effectively to useless using the suction-operated of waste residue
The substances such as the cellulose in liquid carry out adsorption and sedimentation, add additive and carry out the sedimentation such as flocculate to the metal ion of formation, obtain
Metal ion, then it is mixed with acrylamide again, under the action of gaseous mixture, by N, N- carbonyl dimidazoles
Effect, can effectively be such that the cellulose of acrylamide and absorption is combined, while increase the adjusting to metal ion, finally
It is mixed with portland cement etc. again, is squeezed, calcining, the decomposition such as cellulose in calcination process in raw material generate gas
Body, while metal forms melting or semi-molten state, by generating the effect of gas, forms it into foam metal class and is deposited on
The inside of foamed brick, so that it is effectively increased the compression strength and durability of foamed brick, and utilization deposit, additive
It decomposes, can effectively carry out foaming pore-creating, improve porosity.
