Description
Technical field
The present invention relates to a kind of functional material, be particularly well-suited to suppress varieties in saline-alkali areas concrete salt corrosion harm.
Background technology
Varieties in saline-alkali areas is due to dry, and ground surface evaporating capacity causes greatly villaumite, sulfate, carbonate to be enriched with, and causes alkalescence
The highest, this area's concrete works is caused serious salt corrosion, China's saline-alkali soil areal area be soil types according to it and
Weather conditions change determines, is divided into salting district, strand, Huang-Huai-Hai plain salting district, desert and desert steppe salting district, grassland
The big type in four, salting district.Along with the development of railway construction in China, western, inshore railway construction gets more and more, but railroad sleeper
As easy as rolling off a log destruction under severe saline-alkali soil environment, causes concrete durability to decline.Bring tired so to the maintenance in later stage
Difficult.The method of existing suppression varieties in saline-alkali areas concrete corrosion is only through using high durable coating or repairing and reinforcing method
Realizing, the present invention provides a kind of new type functional material, can be used for the digital preservation of varieties in saline-alkali areas concrete, suppresses varieties in saline-alkali areas
Concrete salt corrosion endangers, and solves existing maintenance problems.
Summary of the invention
Present invention aim to address concrete salt corrosion harm under existing saline-alkali environment, the effectively transmission of suppression salt corrosion,
Under disease source concrete protection, suppression adverse circumstances, hazardous medium corrodes, thus significantly improves the durability of concrete.
In the present invention, multiple elements design modification technology is used, first by epoxy-modified polysiloxane, poly-hydroxypropyl methyl sesquialter
Siloxanes, mercapto propyl silane, short fluorine chain fluorine-contaninig polyacrylate, nano aluminium oxide effectively combine modification, utilize epoxide modified poly-
Siloxanes, mercapto propyl silane and the reactivity of alkalescence concrete, increase this material to the adhesive ability of concrete and osmotic energy
Power, particularly sulfydryl functional group, can have special antirust agent effect to rebar surface, can strengthen the rotproofness on its surface, resist
Oxidisability and increase the cementability of itself and concrete；Utilize short fluorine chain fluorine-contaninig polyacrylate, poly-hydroxypropyl methyl silsesquioxane
The protection ultra-violet resistance energy of alkane, the polarizability of C-F key is low, and bond energy is bigger, therefore has the strongest stability and extremely low surface
Can, so that fluoropolymer has good excellent properties, particularly chemical stability and high/low temperature stability.And short fluorine chain
Structure compares perfluor structure and has more preferable pliability and reactivity, it is to avoid perfluorochemical is difficult to explanation, there is migration
Property and the defect of cumulative toxicity.Use poly-hydroxypropyl methyl silsesquioxane modified favourable to short fluorine chain fluorine-contaninig polyacrylate progress
In the chain movement of polymer molecule can be suppressed, improve chemical stability so that it is be suitable for the harsh natural environment of extremely frigid zones,
Thus significantly improve the durability of concrete.Utilize the nano-filled Pinhole closure of nano aluminium oxide, reduce concrete pore rate
Thus improve compactness.
