The invention can be applied to the severe environment with high chloride ion concentration, alternation of wetting and drying, severe cold and the like. The invention has no negative influence on the performance of concrete and has good corrosion resistant effect, and has the functions of reducing water, delaying condensation and bleed air.
Description
Technical field
The present invention relates to a kind of organic composite type antirust for reinforced concrete, specifically a kind of rust inhibitor that has resistance rust, diminishing, slow setting, air-entraining function concurrently.
Background technology
Because the problem of inorganic nitrite rust inhibitor aspect environmental protection, organic rust inhibitor is greatly developed since the eighties in 20th century.Organic reinforcing steel bar rust inhibitor has amine, aldehydes, alkynol class, organo phosphorous compounds, organosulfur compound, carboxylic acid and its esters, sulfonic acid and its esters, heterogeneous ring compound etc. usually, and its advantage is:
(1) under various chlorine ion concentrations, can provide corrosion protection to Steel Concrete.
(2) can in concrete, disperse, thereby can play restraining effect, can antianode corrosion electrochemistry process play restraining effect again reinforcement corrosion electrochemical cathode process.
(3) nontoxic, environmental safety good.
The compound rust inhibitor that with the organism is component not only can be protected reinforcing bar effectively, the more important thing is to stop aqueous medium to enter inside concrete, has improved concrete impervious ability greatly.Can delay concrete weathering process own greatly like this, durability index such as concrete weathering resistance, erosion resistance, frost resistance all are improved.This admixture not only can be used as the reinforcing bar rust inhibitor, is again concrete sanitas simultaneously.In the The Concrete Structure Design theory by being the center with intensity to being today that the center changes day by day with the weather resistance, the concrete weather resistance of reinforcing steel bar is undoubtedly to prolonging the safe operating life of concrete structure, promote industry development significant, also will become the emphasis of concrete research in the Future in China several years.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have anticorrosion performance efficiently, concrete performance is not had negative impact, has a composite type reinforced concrete rust inhibitor of water-reducing property, retarding performance and bleed performance simultaneously.Recommending volume is 2.0%～6% of gelling material gross weight.
A kind of composite type reinforced concrete rust inhibitor is characterized in that, its composition is designated as by weight:
60～200 parts of resistance rust compositions
20～30 parts of water reducer effective constituents
5～15 parts of slow setting composition Sunmorl N 60Ss
0.2～1 part of bleed composition alkyl sodium sulfonate
330～580 parts in water
Described resistance rust composition is the mixture of alcohol, organic acid and amine; Described water reducer is polycarboxylic acids dehydragent vinylformic acid-big monomer of itaconic acid-propenoic acid methoxyl group polyoxy glycol, and described water reducer effective constituent umber is the solid content of this water reducer.
Described resistance rust composition is the mixture of alcohol, organic acid and amine.Wherein alcohol is propyl carbinol, primary isoamyl alcohol, ethylene glycol, glycerol, 1, the mixture of one or more in the 4-butynediol.Organic acid is one or more a mixture of vinylformic acid, methacrylic acid, hexanodioic acid.Amine is one or more the mixture in thanomin, diethanolamine, the diethylenetriamine.The selected water reducer of the present invention is the big monomer of polycarboxylic acids dehydragent AA-UDA-vinylformic acid methoxyl group polyoxy glycol, and solid content is 40%, and water-reducing rate is 25%, and as mentioned above, the addition content of this water reducer should be 50～75 parts.
The present invention can be applicable to chlorine ion concentration higher, severe environment such as alternation of wetting and drying and severe cold are arranged.The present invention does not have negative impact to concrete performance, has good resistance rust effect, and has the function of diminishing, slow setting and bleed concurrently.
