Description
Technical field
The present invention relates to a kind of single polymer modified waterproof asphalt material and preparation method thereof, be specifically related to a kind of vinyl acetate-ethylene copolymerization emulsions and petroleum emulsification pitch and other auxiliary agent and carry out blend and obtain waterproof paint that is fit to blade coating, spraying and preparation method thereof.
Technical background
Asphalt waterproofing paint is a kind of waterproof paint of emulsion-type, can adopt the modes such as spraying, roller coating or manual brushing to use, and by the breakdown of emulsion water evaporates, forms a kind of jointless waterproof, damp-proof membranes.China's oil pitch aboundresources, cheap, and the bituminous composition water resistance is better, constructing operation is simple, therefore the asphalt waterproofing paint application is more, is widely used in highway, bridge, indoor, waterproof, protection against the tide and the various pipeline of roofing, the protection against corrosion of concrete surface.But traditional asphalt liquid water-proofing coating mostly is two components to be formed, thereby require to keep in use two good component proportions, even existing single component bituminous liquids waterproof paint also exists constructional method single, the defect that performance after construction technology and film forming is undesirable, be subject to certain impact while making it use under different working conditions.
Publication number is that CN 1083506A discloses a kind of " mastic neoprene water-proof paint and production technique thereof ", mainly by cut oil pitch, polychloroprene latex, U-Ramin MC, emulsifying agent TOT, 1788 type PVA etc., forms a kind of single component asphalt waterproofing paint of preparation.It is high that this waterproof paint has cohesive strength, rete high resilience, the characteristic such as corrosion-resistant, ageing-resistant.But the petroleum pitch waterproof paint high thermal resistance with pure neoprene latex modification is undesirable, and can be clamminess in the membrane waterproofing surface under the summer solar radiation, and the existence of water-soluble 1788 type PVA is clamminess after also can making rete meet water in addition.
Publication number is that CN 1935930A discloses " a kind of preparation method of ethylene-ethylene acetate copolymer asphalt water-proof coiled material ".Directly extrude and make after utilizing master batch of bitumen and ethylene-vinyl acetate copolymer mixing and stirring, more all kinds of coiled material performances of the coiled material of making all increase, but the waterproof coiled material construction process is complicated, and stickiness is poor than coating.
Publication number is that CN 101113276A discloses " a kind of coating composition that contains acetate ethylene copolymer ".Two kinds of basal component take ethene-vinyl acetate copolymer fluid and ethylene bottom oil as coating, add various fillers and auxiliary agent, make coating and have the advantages such as good water-fast weathering resistance, flexibility, wet viscosity, this method is had relatively high expectations for envrionment temperature, be not suitable for the operation in winter, the ethylene bottom oil Long Term Contact in product can damage human body.
The development of Yan Hui tinkling of pieces of jade high-elastic modified asphalt waterproof paint/Chinese science and technology information, adopt highly-chlorinated polyethylene, penton, styrene-butadiene-styrene block copolymer, CSR rubber four kind superpolymer to pitch carry out modification at 2005 (24): 181.When superpolymer content reaches 23%, when asphalt content reaches 25%, the coating tensile strength is higher than 0.5MPa, elongation at break is higher than 400%, heat-resisting, cold-resistant, ageing-resistant performance is good, needs to add mixed solvent in the standby coating process of this legal system, and certain toxicity is arranged, can to a certain degree pollution be arranged to environment simultaneously, not meet the requirement of novel environment friendly coating.
Publication number is that CN101235252A discloses " a kind of multifunctional liquid rubber spray-coating material ", formed by A, B two components, the A component is polychloroprene latex, poly-styrene-butadiene latex, emulsified bitumen composition, B component condensing agent mainly is comprised of calcium chloride, sodium-chlor etc., A, B component by the waterproof glued membrane that sprays rear formation have that cohesiveness is strong, heatproof, weather-proof, chemical stability, insulativity and the good characteristics of puncture resistance.But two-component coating A, B component in spraying process will keep certain proportioning, during it forms in addition, calcium chloride, sodium-chlor can not lose because of the volatilization of moisture content, but forever be present in formed waterproof glued membrane, calcium chloride, sodium-chlor have certain corrodibility and water-absorbent, thereby its water-repellancy on rete has bad impact.
Above-described various eu-bitumen waterproof paint, in use viscosity is usually unadjustable for it, be beneficial to spraying and just be unfavorable for blade coating if viscosity is rarer, if the thicker blade coating that is conducive to of viscosity just is unfavorable for spraying, constructional method is dumb,, if while adding water or solvent cut when viscosity is thicker, affect film forming properties.
