Abstract
The invention discloses a fluorine-containing organic silicon waterproof material which is prepared from the following raw materials in parts by weight: 20-30 parts of fluorine acrylic resin 30-40 parts of polyacrylamide modified resin, 8-10 parts of paraffin, 5-8 parts of polyvinyl alcohol, 18-28 parts of sodium chloride, 20-30 parts of polyvinyl alcohol modified resin, 10-20 parts of organosiloxane, 5-10 parts of silane coupling agent and 3-5 parts of Lewis acid. The fluorine-containing organic silicon waterproof material has the advantages of favorable water resistance, favorable oil resistance, favorable weather resistance, favorable pollution resistance and favorable adhesiveness.
Description
Technical field
The present invention relates to road surface, bridge, tunnel water proofing technical field, be specifically related to a kind of fluorine-containing organic silicon water-proof material.
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, the corrosion of even water conservancy project, Accommodation, all be unable to do without the effect of water.Therefore, waterproof is the important measures that improve 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.Existing market prospect is reasonable is waterproofing agent of organosilicon.Because waterproofing agent of organosilicon has good water resistance, effectively organize the intrusion of moisture, organosilicon material has again excellent oxytolerant, ozone, action of ultraviolet light simultaneously.Silicoorganic compound have become Jian and have built the main raw of Cai Liao Dwelling water treatment, in the time that organosilicon material is painted on silicate base material surface or mixes in its mixture, with the siloxanes of reactive behavior, not only can the interaction by active group form reticulated hydrophobic silicone film, can also with silicate base material in hydroxyl generation condensation reaction form the silane chain of end with alkyl.This hydrophobic reticulated siloxane molecule film has very low surface tension, can be evenly distributed on wall.Fluorine is the element of electronegativity maximum in the periodic table of elements, and its atomic radius is only slightly large than hydrogen atom, has minimum polarizability.So the chemical resistant properties of fluorochemicals is fabulous.Meanwhile, floating first daughter nucleus is very strong to the constraint of its extranuclear electron and bonding electrons cloud, and C-F bond polarization is low, lower containing C-F Intermolecular Forces, thereby has surface property specially, shows as water tolerance, oil-proofness and staining property.Therefore, fluorine-containing organic silicon water-resisting agent has good water-repellancy, oil-proofness, weathering resistance, anti-staining property and tack.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is that a kind of fluorine-containing organic silicon water-proof material is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of fluorine-containing organic silicon water-proof material, raw material by following parts by weight is made: 20 parts-30 parts of perfluoroalkyl acrylate resins, 30 parts-40 parts of polyacrylamide modified resin, 8 parts-10 parts, paraffin, 5 parts-8 parts of polyvinyl alcohol, sodium-chlor is 18 parts-28 parts, 20 parts-30 parts of polyvinyl alcohol modification resins, 10 parts-20 parts of organo-siloxanes, 5 parts-10 parts of silane coupling agents, 3 parts-5 parts of Lewis acid.
Beneficial effect of the present invention: there is good water-repellancy, oil-proofness, weathering resistance, anti-staining property and tack.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1, a kind of fluorine-containing organic silicon water-proof material, raw material by following parts by weight is made: 20 parts of perfluoroalkyl acrylate resins, 30 parts of polyacrylamide modified resin, 8 parts, paraffin, 5 parts of polyvinyl alcohol, sodium-chlor is 18 parts, 20 parts of polyvinyl alcohol modification resins, 10 parts of organo-siloxanes, 5 parts of silane coupling agents, 3 parts of Lewis acid.
Embodiment 2, a kind of fluorine-containing organic silicon water-proof material, raw material by following parts by weight is made: perfluoroalkyl acrylate resin part, 40 parts of polyacrylamide modified resin, 10 parts, paraffin, 8 parts of polyvinyl alcohol, sodium-chlor is 18 parts, 30 parts of polyvinyl alcohol modification resins, 20 parts of organo-siloxanes, 10 parts of silane coupling agents, 5 parts of Lewis acid.
