Embodiment 1

[0037] The autoclaved aerated concrete slab reinforcement rust inhibitor of the present invention comprises 20-30 parts of latex, 7-8 parts of quartz sand, 4-5 parts of mixed solution, 1-2 parts of lime, 0.5-1 part of iron oxide red, and water 2 to 3 servings. Wherein said mixed solution comprises 0.1-0.3 parts of sodium hydroxide, 0.1-0.3 parts of thickening agent and 4-5 parts of water.

[0038] When the present invention is concretely implemented, described latex preferably adopts that density is 1kg / m 3 , Viscosity of 500mpa s hydroxybutadiene latex to achieve. And described lime then preferably adopts relative density to be 2.5kg / m 3 , slaked lime with a melting point of 5320°C and a pH of 12.6. At the same time, the iron oxide red is preferably used with a relative density of 52.3kg / m 3 , Synthetic iron oxide red with a fineness of 8um and a melting point of 1650°C. The described tackifier preferably adopts an oily tackifier with a relative molecular weight of 1600 ...

Embodiment 2

[0048] This embodiment is basically the same as Embodiment 1, the difference is:

[0049] The latex in the present embodiment is 25 parts, the quartz sand is 8 parts, the mixed solution is 4.5 parts, the lime is 2 parts, the iron oxide red is 0.8 part, and the water is 3 parts. And the sodium oxide in the mixed solution is 0.1 part, the tackifier is 0.2 part, and the water is 4.5 parts.

[0050] The preparation method of the autoclaved aerated concrete slab steel bar antirust agent of the present embodiment is basically the same as the preparation method of embodiment 1, and its difference is:

[0051] When adding slaked lime to the latex after stirring in this embodiment, the mixer is controlled to stir clockwise at a speed of 1500 min for 8 min, then settle for 5 min, and then stir counterclockwise at a speed of 800 r / min for 8 min. After mixing sodium hydroxide, tackifier and water in advance, and stir with a mixer at a speed of 150r / min for 10min to obtain a mixed solutio...

Embodiment 3

[0053] This embodiment is basically the same as Embodiment 1, the difference is:

[0054] The latex in the present embodiment is 30 parts, the quartz sand is 7.5 parts, the mixed solution is 5 parts, the lime is 1.5 parts, the iron oxide red is 1 part, and the water is 2.5 parts. And the sodium oxide in the mixed solution is 0.2 parts, the tackifier is 0.1 parts, and the water is 5 parts.

[0055] The preparation method of the autoclaved aerated concrete slab steel bar antirust agent of the present embodiment is basically the same as the preparation method of embodiment 1, and its difference is:

[0056] In this embodiment, when slaked lime is added to the homogenized latex for stirring, the mixer is controlled to stir clockwise at a speed of 2000 min for 10 min, then settle for 5 min, and then stir counterclockwise at a speed of 1000 r / min for 10 min. After mixing sodium hydroxide, tackifier and water in advance, and stir with a mixer at a speed of 200r / min for 8min to obtai...

Abstract

The invention discloses an antirust agent for autoclaved aerated concrete plate reinforcements and a preparation method of the antirust agent. The antirust agent is characterized by being prepared from the following components of 20 to 30 parts of latex, 7 to 8 parts of quartz sand, 4 to 5 parts of mixing solution, 1 to 2 parts of lime, 0.5 to 1 part of iron oxide red and 2 to 3 parts of water. The prepared antirust agent for the autoclaved aerated concrete plate reinforcements has the advantages that the requirements of GB15762-2008 are met, the high temperature-resistant property and the acid and alkaline-resistant property are realized, and the poisonless and environment-friendly properties are realized; the antirust agent cannot generate chemical reaction even if the antirust agent is in contact with cement, lime, silica sand and the like for a long time, so that the reinforcements subjected to antirust treatment cannot easily get rusty, and the service life and use safety of autoclaved aerated concrete plates can be well guaranteed.

Description

technical field [0001] The invention relates to an antirust agent, in particular to an autoclaved aerated concrete plate reinforcement antirust agent and a preparation method thereof. Background technique [0002] The autoclaved aerated concrete slab is a concrete slab with porous crystals, which is made of cement, lime, silica sand, steel bars, etc. as the main raw materials, which are cured by high temperature, high pressure, and steam. During the production of autoclaved aerated concrete slabs, it is necessary to carry out anti-rust treatment on the steel bars to prevent the steel bars from chemically reacting with cement, lime, silica sand, etc., and the rusting of the steel bars will cause the strength of the steel bars to weaken, thus affecting the autoclaved aerated concrete slab. The service life and safety of air concrete slabs. [0003] At present, people use common anti-rust agents to anti-rust the steel bars of autoclaved aerated concrete slabs, and ordinary ant...
