Abstract

The invention discloses a polymer modified emulsified asphalt composition and a preparation method thereof, wherein the component A of the polymer modified emulsified asphalt composition comprises cationic-type emulsified petroleum asphalt, cationic-type neoprene latex, non-ionic-type epoxy resin emulsion and additives; the B component of the polymer modified emulsified asphalt composition comprises industrial alcohol, a waterborne epoxy resin curing agent and industrial water. When the components A and B are sprayed on the surface of a sprayed object at the same time, the components A and B are rapidly settled and cured to form a polymer asphalt water-proof glue film layer; the various large molecules in the glue film layer interact to form a semi-interpenetrating network structure; under the synergistic effect of the additives, the water-proof material glue film has the characteristics of favorable weather resistance, adhering force, stretching intensity, elongation rate, water resistance, seepage resistance, dampness resistance, corrosion resistance and the like, and the polymer modified emulsified asphalt composition can be widely applied to the fields of water resistance and dampness resistance of medicine and gun powder warehouse, as well as the direct water resistance, seepage resistance, corrosion resistance and the like of metal roofing.

Description

technical field [0001] The invention relates to an emulsified asphalt composition and a preparation method thereof, in particular to a polymer-modified cationic emulsified petroleum asphalt building waterproof material composition and a preparation method thereof. The waterproof material formed by the composition can be widely used in the fields of civil buildings, tunnels, dams, garbage landfills, anti-leakage, moisture-proof warehouses and the like. technical background [0002] Waterproof material is a kind of building material chemical products involving thousands of households. Usually, this material is in the form of viscous liquid or solid powder with no fixed shape at room temperature to form a paste with water. Through the volatilization of solvent or water volatilization or reaction After curing, a tough film layer is formed to achieve the purpose of waterproof and anti-seepage. At present, waterproof materials are mainly divided into two categories: solvent-based...
