Description
Technical field
The present invention relates to building chemical field, more particularly to a kind of production technology of chemical building material anti-corrosive rust inhibitor.
Background technology
Since steel bar corrosion causes the destruction of reinforced concrete structures to have become worldwide problem.Cause steel bar corrosion
The main reason for be villaumite.On the one hand villaumite comes from concrete raw material, such as mixing water, sea sand, anti-cryosel, salt fog and villaumite
(or containing villaumite) additive etc.；On the other hand use environment is come from, China contains bar in chlorine salt solution under having been considerably, removes coastal area
Outside, the industrial environment etc. that also salt-soda soil, Salt Lake Area and salt pollute.Chlorion can penetrate concrete and reach rebar surface, break
Bad rebar surface oxide passivation film and make steel bar corrosion.After iron is converted to iron rust, with the increase of volume, volume can increase
To 6 times of iron, causing concrete cover to be expanded with reinforcing bar and crack, play drum, peels off, reinforcing bar loses protection completely, therefore, steel
The corrosion rate of muscle can faster, and corrosion keeps reinforcing bar section impaired, the mechanical property of reinforcing bar itself is reduced, especially to being in high stress
High strength wire under state, corrosion susceptibility higher, it may occur however that be broken and cause the accident suddenly, as successfully managing
Means, corrosion inhibitor are widely applied in armored concrete, and anti-corrosive rust inhibitor currently used in the market is all and chemical building material
It is used after mixing, it can only be according to the effect for mixing corrosion inhibitor therein so as to cause the corrosion-prevention rust-resistance ability of chemical building material
Resistance rust is carried out, further maintenance work can not be carried out to the concrete after partial coagulation and therefore invent a kind of chemical building material
The production technology of anti-corrosive rust inhibitor is necessary to solve the above problems.
Invention content
The purpose of the present invention is to provide raw material A and raw material B are mixed obtained corrosion inhibitor, to solve chemical building material
Corrosion-prevention rust-resistance ability can only carry out resistance rust according to the effect for mixing corrosion inhibitor therein, can not be to the coagulation after partial coagulation
Soil carries out the problem of further maintenance work.
To achieve the above object, the present invention provides the following technical solutions：A kind of production work of chemical building material anti-corrosive rust inhibitor
