Description

A kind of micro-nano reinforced steel bar rust preventing agent and preparation method thereof of autoclaved aerated concrete slab
Technical field
The invention belongs to autoclaved aerated concrete slab technical field, and in particular to a kind of autoclaved aerated concrete slab micro-nano Rice reinforced steel bar rust preventing agent and preparation method thereof.
Background technology
Autoclaved aerated concrete slab is important a member in steam pressurized foam concrete, be a kind of green lightweight, insulation, Heat-insulated and excellent in mechanical performance construction material, can be used as internal partition wall, exterior wall, floor and roofing, have factory normalization production, It can saw, can cut, it is easy for installation, many advantages, such as manpower can be saved and shortened the construction period.With the further hair of China's building energy conservation Exhibition, the continuous propulsion of housing industrialization and Building technology change to industrial design, factorial praluction, fabricated construction, steam pressure Air entrained concrete plate will have the larger market demand, and prospect is very wide.
Autoclaved aerated concrete slab is a kind of reinforcements, has certain thickness of protection tier, but since steam pressure adds Gas concrete substrate is closely knit unlike normal concrete, has very high porosity and high alkalinity, therefore cannot be effectively Corrosion does not occur for the reinforcing bar for protecting it internal.On the contrary, because of the hygroscopicity of product during its steaming pressuring curing process and use, reinforcing bar Easily corroded by electrolyte, oxygen, chlorion etc..Therefore must have different from ordinary concrete member in the use of reinforcing bar Antirust treatment, its usual way are applying preventive by dipping agent.
According to the performance and production technology characteristic of autoclaved aerated concrete slab, antirust agent is mainly commented in terms of three Valency:First is antirust ability;Second is to use process complexity;3rd is the cohesive force with reinforcing bar and base material.Production at present The reinforced steel bar rust preventing agent used during autoclaved aerated concrete slab is mainly with levigate sand, lime, cement, water paint or emulsified asphalt etc. As the main component, the rustless property of these kind antirust agent is good, but in the prevalence of reinforcing bar cohesive force it is relatively low the problem of, and by In levigate sand than great, layering of easily sinking during use, even if stirring also is difficult to be uniformly dispersed, so as to have impact on steam pressurized mixed The structural behaviour of concrete board and quality control.
The content of the invention
In order to overcome the disadvantages mentioned above of the prior art and deficiency, it is an object of the invention to provide a kind of steam pressurized coagulation The micro-nano reinforced steel bar rust preventing agent of native plate, antirust agent of the invention are remarkably improved the cohesive force of reinforcing bar and base material, when improving use Subsidence problems are layered, improve the uniformity and rustless property of reinforcing bar dip-coating.
