Embodiment Construction

[0019] The waste liquid is made by mixing papermaking waste liquid and pickling waste water in a volume ratio of 5-7:4-8.

[0020] The waste slag is aluminum ash and steel slag according to the mass ratio of 4-8:5-7, which is ground at 600r / min for 30 minutes to obtain the final product.

[0021] The additive is made by mixing polyacrylamide and sodium humate at a mass ratio of 4:1-2.

[0022] The mixed gas is a mixture of hydrogen and oxygen in a molar ratio of 3:2~5.

[0023] The additive is N,N-carbonyldiimidazole.

[0024] The surfactant is any one of fatty alcohol polyoxyethylene ether and dodecylamine propionate.

[0025] A kind of preparation method of foam brick, this preparation method comprises the steps:

[0026] (1) Mix waste liquid and waste residue at a mass ratio of 7-9:3-5, ball mill at 500r / min for 50min, collect the ball-milled product, put the ball-milled product and additives into a container at a mass ratio of 7-9:2, and grind at 300r / min / min Stir and...

Abstract

The invention relates to a preparation method of a foam brick, which belongs to the technical field of building materials. Waste solution and waste residues are used as raw materials, so that the production cost can be effectively reduced; by virtue of the effect of the waste solution for on the waste residues, a metal substance in the waste residues presents exists in an ion form; by utilizing the absorption effect of the waste residues, the substances of cellulose and thelike in the waste solution can be effectively absorbed and settled; the formed metal ions can be settled in a flocculationmanner by adding the additives, the metal ions can be obtained, then the metal ions can be mixed with acrylamide, under the effect of the mixed gas, and by virtue of the effect of N,N-carbonyl diimidazole, the acrylamide can be effectively combined with the absorbed cellulose, the adjustment for the metal ions can be improved, finally the mixture is mixed with silicate cement and the like to be extruded and calcined, and by virtue of the effect of the produced gas, foam metals are deposited inside the foam brick, so that the pressure compressiveresisting strength and durability of the foam brick can be effectively improved.

Description

technical field [0001] The invention relates to a method for preparing foam bricks, which belongs to the technical field of building materials. Background technique [0002] With the development of construction technology, buildings tend to be high-rise and large-scale. Therefore, reducing the structural weight of high-rise buildings and developing lightweight thermal insulation wall materials have become very important issues. With the continuous improvement of building energy-saving requirements, the amount of lightweight and high-durability wall materials will continue to increase. In recent years, due to a series of freeze-thaw deterioration phenomena in aerated concrete engineering, a serious shortage of lightweight wall materials has been caused. Therefore, it is necessary to develop new lightweight wall materials. With the continuous development of the economy, people's living standards are also constantly improving, and they have put forward higher and newer requi...
