Abstract

The invention discloses emulsified asphalt with a high softening point and a preparation method. The emulsified asphalt with the high softening point is prepared from the following raw materials in parts by weight: 40-60 parts of pittasphalt, 5-15 parts of dodecyl dimethyl benzyl ammonium chloride, 5-10 parts of fatty acid methyl ester polyethenoxy ether, 2-8 parts of sodium cellulose glycolate, 5-10 parts of isobutyl acrylate and 20-43 parts of water. The vicat softening point of the emulsified asphalt is higher than that of plain asphalt, the emulsified asphalt can be used as a protective paint for metal, is capable of forming a compact coating, increasing the shielding property of an emulsified asphalt coating on a metal substrate and further improving the corrosion resistance of the emulsified asphalt coating. The preparation method is simple and convenient, the used raw materials are easily available, and environmental pollution is less.

Description

technical field [0001] The invention relates to a high softening point emulsified asphalt, in particular to a high softening point protective coating emulsified asphalt. Background technique [0002] The so-called emulsified asphalt is an oil-in-water asphalt emulsion formed by dispersing the asphalt in a state of fine particles in an aqueous solution containing an emulsifier after heat-melting and high-speed mechanical shearing. The asphalt of this dispersion system is the dispersed phase, and the water is the continuous phase, which has good fluidity at room temperature. Petroleum asphalt has good adhesion, anti-aging and waterproof and anti-corrosion capabilities, and has been widely used as road construction and sealing materials for a long time. At present, the loss caused by metal corrosion is very serious, especially the anti-corrosion of steel has attracted increasing attention at home and abroad, and coating anti-corrosion coatings is one of the main methods to pre...
