Abstract
The invention discloses a fluorine-containing organosilicon waterproof material for cement concrete, which is prepared from 20-30% of fluorine-containing acrylic resin, 30-40% of polyacrylamide modified resin, 20-30% of polyvinyl alcohol modified resin, 10-20% of organosiloxane, 5-10% of silane coupling agent and 3-5% of Lewis acid. The fluorine-containing organosilicon waterproof material for cement concrete disclosed by the invention has the advantages of favorable water resistance, oil resistance, weather resistance, pollution resistance and adhesiveness.
Description
Technical field
The present invention relates to road surface, bridge, tunnel water proofing technical field, especially relate to a kind of cement concrete with fluorine-containing organic silicon water-proofing material and preparation method thereof.
Background technology
Water is to cause concrete structure and Steel Concrete to accept the important substance that weather resistance is damaged.No matter be soft water erosion, freeze-thaw damage, alkali, the steel bar corrosion of cement concrete, even the corrosion of water conservancy project, Accommodation, all be unable to do without the effect of water.Therefore, waterproof is the important measures that improve the cement concrete constructions weather resistance.The water-proof material of China mainly contains at present: polymer modified bituminous waterproof sheet material, synthetic polymeric waterproofing material, waterproof paint, sealing material, injection material, waterproof mortar, bentonite waterproof material, water-resisting agent etc.The existing market prospect is reasonable to be waterproofing agent of organosilicon.Because waterproofing agent of organosilicon has favorable waterproof property, effectively organize the intrusion of moisture, organosilicon material has excellent oxytolerant, ozone, action of ultraviolet light again simultaneously.Organosilicon compounds have become the main material of building dwelling on top of wooden stakes treatment, when the organic silicon material brushing the substrate surface or incorporated into the silicate material when mixing with reactive siloxane, not only through the active a group formed by the interaction network hydrophobic siloxane film, but also with silicate base condensation reaction with the hydroxyl group-containing silane to form terminally chains.This hydrophobic reticulated siloxane molecule film has very low surface tension, can be evenly distributed on the wall.
Fluorine is the maximum element of electronegativity in the periodic table of elements, and its atomic radius is only big slightly than Wasserstoffatoms, has minimum polarizability.So the chemical resistant properties of fluorochemicals is fabulous.Simultaneously, floating first daughter nucleus is very strong to the constraint of its orbital electron and bonding electrons cloud, and C-F bond polarization property is low, and it is lower to contain the C-F Intermolecular Forces, thereby has surface property specially, shows as water tolerance, oil-proofness and staining property.Therefore, fluorine-containing waterproofing agent of organosilicon has excellent waterproofness, oil-proofness, weathering resistance, anti-staining property and tack.
Summary of the invention
The object of the present invention is to provide a kind of environment-friendly type water cement concrete with fluorine-containing organic silicon water-proofing material with excellent waterproofness, oil-proofness, weathering resistance, anti-staining property and tack.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of cement concrete comprises component and content (weight percentage) with fluorine-containing organic silicon water-proofing material:
More excellent is: described fluoroacrylic resin is methylacrylic acid ten difluoro fat in heptan.
More excellent is: described SEPIGEL 305 modified resin is for being the SEPIGEL 305 modified resin of properties-correcting agent with the methylcellulose gum.
More excellent is: described polyvinyl alcohol modification resin is for being the polyvinyl alcohol modification resin of properties-correcting agent with the CMC 99.5.
More excellent is: described organo-siloxane is two functional group's organo-siloxanes.
More excellent is: described silane coupling agent is KH550, KH570 or A151.
More excellent is: described Lewis acid is the fluoroform sulphonate of aluminum chloride, iron(ic)chloride, boron trifluoride, columbium pentachloride or lanthanon.
The present invention also provides a kind of method for preparing cement concrete with fluorine-containing organic silicon water-proofing material, comprises step:
A) fluoroacrylic resin, SEPIGEL 305 modified resin, polyvinyl alcohol modification resin, organo-siloxane are mixed in the input reaction kettle by certain ratio row, heated and stirred is about 0.5 hour;
B) a certain amount of silane coupling agent was joined in the reaction kettle heated and stirred about 1 hour;
