Abstract
The invention provides an organic composite reinforcing steel bar rust inhibitor for reinforced concrete and a method for preparing the same. The organic composite reinforcing steel bar rust inhibitor of the invention comprises the following components in percentage by mass: 10.0 to 30.0 percent of epoxy modified polyamine, 5.0 to 15.0 percent of sodium monoflurophosphate, 0.01 to 10.0 percent of cyclohexylamine carbonate (CHC), 0.01 to 0.5 percent of antifoaming agent and 45 to 84 percent of water. The organic composite reinforcing steel bar rust inhibitor of the invention has good rust inhibiting effect on the reinforcing steel bar in the concrete, has long duration for corrosion inhibition, has no adverse effect on the durability of the concrete and can be widely applied to newly constructed reinforced concrete structures such as harbor work, coastal buildings, buildings at alkaline land, civil buildings and the like with requirements on corrosion resistance of the reinforcing steel bar.
Description
Technical field
The present invention relates to a kind of organic reinforcing steel bar rust inhibitor that is used for Steel Concrete, be specifically related to a kind of organic composite type reinforcing bar rust inhibitor and preparation method thereof, also introduced the application of this organic clad steel bar rust inhibitor simultaneously, belong to building material technical field.
Background technology
By the structure that Steel Concrete constitutes, concrete has at least two kinds of functions, and promptly absorption pressure shrinkage strain and protection reinforcing bar are not corroded.Action of steel bars is to bear tensile stress and shear-stress.
Annual concrete reinforcement erosion not only causes the engineering construction heavy economic losses to country, also causes the waste and the environmental pollution of resource simultaneously, even causes great life and property loss.At present, in order to prevent and control the corrosion of reinforcing bar in the concrete and the work-ing life of extending structure, one of most convenient effective measures are exactly the application of reinforcing bar rust inhibitor.Nitrite be in the concrete research use the earliest, maximum a kind of rust inhibitor, still, along with the enhancing of people's environmental consciousness, and the carinogenicity of nitrite draws attention day by day, a lot of countries have banned use of such rust inhibitor product.In addition, the nitrites rust inhibitor belongs to the oxidized form inhibiter, corrosion mitigating effect is only just arranged when consumption is enough, otherwise can cause serious local corrosion, brings hidden danger to structure.
For these reasons, environmentally friendly organic rust inhibitor has obtained very great development in latter stage in 20th century.Such rust inhibitor has characteristics such as corrosion inhibition is stable, environmental protection, is the developing direction of concrete steel bar rust inhibitor.Research and development of the organic compound rust inhibitor of Environmental Protection in China type at present and production also do not have the sophisticated organic clad steel bar rust inhibitor of the environment-friendly type product that scale is arranged still in the starting stage.
Summary of the invention
The object of the present invention is to provide a kind of organic clad steel bar rust inhibitor that is used for Steel Concrete and preparation method thereof.It has efficient durable safe, eco-friendly characteristics.
The organic clad steel bar rust inhibitor that is used for Steel Concrete that the present invention proposes is a kind of water soluble liq composite prod.It is made up of epoxide modified polyamine, sodium monoflurophosphate, cyclohexylamine carbonate (CHC), defoamer, water.Each component is prepared as shown in table 1 by mass percentage:
The organic clad steel bar rust inhibitor of table 1 constituent mass proportioning
Epoxide modified polyamine of the present invention is a kind of in epoxide modified diethylenetriamine, epoxide modified triethylene tetramine, the epoxide modified tetraethylene pentamine.Described defoamer is polyether-modified organosilicon oligopolymer.
The preparation method of organic clad steel bar rust inhibitor of the present invention is: take by weighing epoxide modified polyamine earlier, join in container or the stirring tank, when being heated to 30～40 ℃ of temperature, the water, cyclohexylamine carbonate (CHC), the sodium monoflurophosphate that under whipped state, successively add specified amount then, after being stirred well to uniform dissolution, the defoamer that adds specified amount more promptly gets this product after continuing to stir.
Organic clad steel bar rust inhibitor of the present invention has good resistance rust effect for steel bars in concrete, and the inhibition longer duration, and durability of concrete is had no adverse effects.Establishing criteria " reinforcing bar rust inhibitor use technology rules " YB/T 9231 tests, specific targets see the following form 2:
Table 2 concrete steel bar rust inhibitor performance index
But organic clad steel bar rust inhibitor of the present invention widespread use and harbour engineering, coastal building, saltings regional architecture, covil construction etc. have the newly-built skeleton construction of steel bar anti-corrosion requirement.
