Abstract
The invention relates to a composite type reinforced concrete rust inhibitor, which is composed of the following raw materials by weight: 30-50 parts of 1, 1', 1''-nitrilotri-2-propanol, 20-30 parts of ethylenediamine, 15-20 parts of copper phosphate, and 60-80 parts of deionized water. The composite type reinforced concrete rust inhibitor provided by the invention can form an organic passivation protective membrane on a steel bar surface, and the corrosion inhibition effect can effectively obstruct erosion of chloride ion and oxygen ions. The rust inhibitor provided by the invention adopts a reasonable proportion, and compositions can reach a good synergistic effect, thus maximumly playing a rust inhibiting role.
Description
Technical field
The present invention relates to a kind of composite type reinforced concrete rust inhibitor, belong to building anti-corrosion Material Field.
Background technology
When concrete weather resistance refers to that concrete stands physics or the chemical action of environment for use, physical environment and material internal factor, concrete keeps the ability of the performance of self work capacity.Wherein, steel bar corrosion is one of principal element affecting Steel Concrete weather resistance.
Rust inhibitor is mixed in concrete, its effect is not stop the harmful ion in environment to enter into concrete, but after objectionable impurities enters concrete, utilize its resistance rust effect, reduce harmful ion corrosive power, steel bar corrosion process is suppressed, thus delays corrosion, extend the work-ing life of Steel Concrete.
Mix rust inhibitor in Steel Concrete, construct simply, conveniently, save time and cost.Compared with the methods such as galvanic protection, successful, cost is low.In recent years, mixing reinforcing steel bar corrosion inhibitor has become the universal method of postponing the steel bar corrosion time and slowing down corrosion rate, and is simple, the most economic and effective technical measures.
Summary of the invention
The object of this invention is to provide a kind of composite type reinforced concrete rust inhibitor, rust inhibitor of the present invention greatly can reduce and slow down corrosion rate, resistance rust is effective.
Technical scheme of the present invention is: a kind of composite type reinforced concrete rust inhibitor, is made up of: 1,1' the raw material of following weight part, 1''-nitrilo three-2-propyl alcohol 30-50 weight part, quadrol 30-50 weight part 20-30 weight part, 15-20 parts by weight of phosphoric acid copper, deionized water 60-80 weight part.
The preparation method of described composite type reinforced concrete rust inhibitor is even by 1,1', 1''-nitrilo three-2-propyl alcohol after weighing, quadrol, cupric phosphate, deionized water and stirring successively.
The invention has the beneficial effects as follows: can form organic passivation protection film at rebar surface, its corrosion mitigating effect effectively can intercept the erosion of chlorion and oxonium ion.Rust inhibitor of the present invention adopts rational proportion, has good synergistic effect between composition, at utmost plays the effect of resistance rust.
Embodiment
In following the present embodiment, at different temperatures, reinforcing bar is immersed in the full conjunction aqua calcis of 4.5% NaCl concentration, the anticorrosion performance of reinforcing bar is detected.Wherein reinforcing bar is the cylinder sample reinforcing bar of diameter d=l5mm, 15mm*50mm.Calculate the rate of weight loss not mixing, mix 1.5g reinforcing bar in etchant respectively.Rate of weight loss=(m1-m2)/m1 × 100%, in formula, m1, m2 are respectively the weight of reinforcing bar before and after corrosion.Corrosion inhibition rate=(E1-E2)/E1 × 100%, in formula, E1, E2 are respectively the rate of weight loss mixing reinforcing bar before and after rust inhibitor.Corrosion inhibition rate represents the provide protection size of rust inhibitor to reinforcing bar, and corrosion inhibition rate is larger, then provide protection is larger.
Embodiment 1
At 20 DEG C 4.5% NaCl concentration full conjunction aqua calcis reinforcing bar in soak 240h after, calculate the rate of weight loss not mixing, mix 1.5g reinforcing bar in etchant respectively.
The present embodiment empty group reinforcement loss weight ratio is 0.68%, and mixing reinforcement loss weight ratio after rust inhibitor is 0.013%, and corrosion inhibition rate reaches 98.1%.
Embodiment 2
At 30 DEG C 4.5% NaCl concentration full conjunction aqua calcis reinforcing bar in soak 240h after, calculate the rate of weight loss not mixing, mix 1.5g reinforcing bar in etchant respectively.
The present embodiment empty group reinforcement loss weight ratio is 0.72%, and mixing reinforcement loss weight ratio after rust inhibitor is 0.035%, and corrosion inhibition rate reaches 95.1%.
Embodiment 3
At 40 DEG C 4.5% NaCl concentration full conjunction aqua calcis reinforcing bar in soak 240h after, calculate the rate of weight loss not mixing, mix 1.5g reinforcing bar in etchant respectively.
The present embodiment empty group reinforcement loss weight ratio is 0.85%, and mixing reinforcement loss weight ratio after rust inhibitor is 0.056%, and corrosion inhibition rate reaches 93.4%.
Above-described embodiment is only and technical conceive of the present invention and feature is described, can not limit the scope of the invention with this, all modifications and variations done according to spirit of the present invention, are all encompassed within protection scope of the present invention.
