Abstract

Building material field of the present invention, discloses a kind of foam cement preparation method, comprises the following steps:1st, water is first added in the mixer for prepare foam cement;2nd, foam stabilizing reinforcing agent is added;3rd, cement and quartz sand are added;4th, hydrogen peroxide is added for the first time, and the deal of added hydrogen peroxide is 1/3rd that this prepares dioxygen water inventory used by foam cement;5th, after stirring 1~5 minute, second adds hydrogen peroxide, and the deal of added hydrogen peroxide is 2/3rds that this prepares dioxygen water inventory used by foam cement;6th, stir 6~8 seconds, be poured into immediately afterwards in mould and foam;7th, after completing maintenance, the demoulding is producing foamed finished cement.The intensity of the foam cement finished product produced using the inventive method is higher than the foam cement that existing technology is produced by 30% or so, and stability and durability are also more preferable.

Description

A kind of foam cement preparation method
Technical field
The invention belongs to building material field, and in particular to a kind of foam cement preparation method.
Background technology
The existing technology for preparing foam cement is broadly divided into two kinds, and one kind is physical blowing, and the bubble that will be produced passes through In mechanical system injection cement slurry so that slurry wraps up bubble, and the material of small dead air space is formed after solidification, and its shortcoming is Lost in foam mechanical mixed process big.Another way is chemical blowing mode, is becomed privileged by being mixed in cement slurry Learn additive(Such as hydrogen peroxide), there is chemical reaction with cement slurry material using additive and produce gas, work as grout cures Afterwards, separate bubble system is formed in solid, its shortcoming is fast expansion rate, it is difficult to control foam stability and one Cause property, the intensity of the foam cement for preparing in addition is also high not enough.
The content of the invention
In order to overcome existing use chemical foaming technology to prepare the above-mentioned deficiency of foam cement, the purpose of the present invention is to carry For a kind of new foam cement preparation method.
The technical solution adopted in the present invention is that a kind of foam cement preparation method comprises the following steps:
1st, water is first added in the mixer for prepare foam cement;
2nd, it is subsequently added into foam stabilizing reinforcing agent;
3rd, cement and quartz sand are subsequently added into;
4 then for the first time add hydrogen peroxide, the deal of added hydrogen peroxide is that this prepares dioxygen water inventory used by foam cement 1/3rd;
5th, after stirring 1~5 minute, second addition hydrogen peroxide, the deal of added hydrogen peroxide is prepared used by foam cement for this 2/3rds of dioxygen water inventory;
6th, and then stir 6~8 seconds, be poured into immediately afterwards in mould and foam;
7th, after completing maintenance, the demoulding is producing foamed finished cement.
The beneficial effects of the invention are as follows:Compared with the disposable technology for adding whole hydrogen peroxide in existing chemical blowing, Hydrogen peroxide is added in the inventive method at twice, its benefit is, after first time adds 1/3rd hydrogen peroxide and stirring, dioxygen The oxidation that water occurs can get rid of the factor for preparing the stabilization that is unfavorable for during foam cement foaming, be unfavorable for so that After adding remaining 2/3rds hydrogen peroxide for the second time, foaming process is more stable, foaming effect is more preferable, the foaming being eventually fabricated Finished cement intensity is higher.The foam cement finished product produced using the inventive method detection indicate that, in same condition Under, its intensity is higher by 30% or so than the foam cement that the technology of existing disposable addition hydrogen peroxide is produced, and stabilization Property and durability are also more preferable.
Specific embodiment
The inventive method is described further below by embodiment.
Raw materials used every part of unit is 1 kilogram in the present embodiment, as follows the step of prepare foam cement:
1st, 115 parts of water is first added in the mixer for prepare foam cement;
2nd, it is subsequently added into 7.5 parts of foam stabilizing reinforcing agent;
3rd, 50 parts of 250 parts of cement and quartz sand are subsequently added into;
5 then for the first time add 2 parts of hydrogen peroxide;
6th, after stirring 1~5 minute, second 4 parts of hydrogen peroxide of addition;
7th, and then stir 6~8 seconds, be poured into immediately afterwards in mould and foam;
8th, after completing maintenance, the demoulding is producing foamed finished cement.
Foam cement finished product can again cut into cement board, foam cement block, foam cement brick etc. with cutting tool and build Build and use unit.
In above-mentioned steps, water temperature is preferably controlled in 90-2X(X is cement temperatures)Degree Celsius, that is, 90-2 times When cement temperatures, such as cement temperatures X are 25 degrees Celsius, water temperature is controlled at 90-2 × 25=40 degrees Celsius, it is demonstrated experimentally that this Individual temperature is most beneficial for foaming and the stabilization of product.
When preparing foam cement using the inventive method, the industry such as flyash, fiber can also be added to prepare foaming water The conventional raw material of mud, above-mentioned foam stabilizing reinforcing agent also includes calcium stearate, odium stearate, high activity miberal powder(Such as high activity silicon Powder), triethanolamine(As waterproofing agent)Conventional foam stabilizer, reinforcing agent, early strength agent, the rapid hardening of foam cement is prepared etc. the industry Agent, waterproofing agent.
It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, may be used also To make some variations and modifications, these also should be regarded as belonging to protection scope of the present invention.
