Description
Technical field
The invention belongs to concrete protection technical field, particularly a kind of Concrete Anti corrodes anti-icing silicone materials and preparation method thereof, can be used for the anti-icing protection of concrete protection against corrosion, improves concrete service life.
Background technology
As everyone knows, concrete must be faced with the erosion of external environment under arms in process, and especially along with China's infrastructure construction is carried out, concrete Service Environment is more and more harsher.Such as, the deteriorated air (SO continued
2, CO
2), the high humidity of coastland and inorganic salt, west area saline and alkaline condition etc., all greatly accelerate concrete deteriorated process, had a strong impact on concrete service life.How to extend concrete structure service life under severe conditions, become the pressing issues that engineering faces.
Concrete deterioration always inside expansion from surface, chloride erosion, Acid rain damages, freeze-thaw cycle, freezing erosion are the major causes causing concrete structure durability to decline, and finally jeopardize the safety of engineering structure.Therefore, under corrosion and freeze-thaw damage environment, only by improving quality and the thickness of concrete protective layer material, cannot ensure that concrete structure safety in design life is on active service, one or more anti-deteriorated enhancements must be taked.
Concrete Anti corrosion technology has obtained concern and the research of a large amount of industry personnel, and some measures also achieve good effect.Reinforcing steel bar corrosion inhibitor, concrete galvanic protection, stainless steel rebar, reinforcing steel bar surface coating, anti-corrosion reinforcing bar etc.; practice shows; concrete surface coating protection method is the method for economical and efficient the most; but there is more deficiency with the conventional surface protective coating that epoxy coat, polyurethane coating are representative; the problems such as poor durability, anti-corrosion capability are limited, so more and more urgent to the requirement of more high performance concrete protective coating.
Concrete Anti icing technology has caused the extensive concern of global scientific research personnel, and the multiple country of some ice damages has set up particular study mechanism, carries out a large amount of scientific researches to icing principle.The ice control solution that anti-icing technology mainly contains Four types is anti-icing, mechanical deicing, and heat energy is anti-icing and coating is anti-icing.The anti-icing principle of solution utilizes anti-freeze fluid to mix with the water collected by stromal surface, because the freezing point of mixed solution reduces greatly, makes that water is unlikely to freeze from the teeth outwards.So-called mechanical deicing, is exactly mechanically that ice is broken, then blows down by air-flow, or utilizes centrifugal force, vibrates ice is removed.Heat energy is anti-icing is exactly utilize various energy heats object, makes article surface temperature more than 0 DEG C, with E to object that is anti-icing or deicing.And ice-covering-proof coating realizes anti-ice object mainly through material surface property and microfacies pattern, this kind of material require has anti-freeze property and ice-phobic concurrently, alleviates even elimination ice and snow gather from sticking power two aspect extending freezing time and reduction ice.From principle, coating is anti-icing is a kind of very desirable anti-icing method, because it belongs to active protection, energy consumption is little, environmental friendliness and applied widely.But existing coating antiicing coating still exists problems such as hydrophobic performance is not good, poor durability.
The low surface energy coatings composition that patent CN103492486A discloses a kind of moisture curable composition and prepares thus, have employed the polymkeric substance based on Silante terminated urethane; But said composition moisture-curable poor controllability, the compatible stability of urethane and polysiloxane is poor, and the phase separation in solidification process is wayward, causes hydrophobic performance unstable.
Patent CN102757708A discloses a kind of Anti-ice paint and preparation method thereof, and the polyacrylic acid grafted PDMS multipolymer containing POSS realizes Anti-ice-and-snow ability, and it has good consistency and sticking power; But its contact angle is less, only have about 105 °, hydrophobic performance is limited.
Patent CN101792631A discloses a kind of high hydrophobic static-electricity conducting anti-icing coating and preparation method thereof, fluorocarbon resin, conducting powder, silicoorganic compound are adopted to prepare a kind of low surface energy antiicing coating with static conductive character, mainly utilize the low surface energy of fluorinated acrylic resin to realize anti-icing effect, protect for wire surface; But, but its resistance to low temperature and low temperature flexibility poor, and the poor durability of fluorinated acrylic resin, can not meet the requirement of concrete digital preservation.
