Embodiment 1

[0026] Take by weighing 55 parts of No. 90 straight run bitumen (penetration is 115) (by weight, the same below), 10 parts of octadecyl dimethyl benzyl ammonium chloride, 5 parts of fatty acid methyl ester polyoxyethylene ether, 5 parts of sodium carboxymethyl cellulose, 8 parts of isobutyl acrylate, and 20 parts of water. The above-mentioned asphalt is heated to 140°C, and then the above-mentioned other raw materials are prepared into a 50°C aqueous solution, and then the asphalt and the aqueous solution are passed through an emulsification device to obtain the emulsified asphalt product for protective coating of the present invention.

Embodiment 2

[0028] Take by weighing 50 parts of No. 100 straight run bitumen (penetration is 105) (by weight, the same below), 16 parts of octadecyl dimethyl benzyl ammonium chloride, 7 parts of fatty acid methyl ester polyoxyethylene ether, 7 parts of sodium carboxymethyl cellulose, 10 parts of isobutyl acrylate, and 30 parts of water. The above-mentioned asphalt is heated to 150°C, and then the above-mentioned other raw materials are prepared into an aqueous solution at 60°C, and then the asphalt and the aqueous solution are passed through an emulsification device to obtain the emulsified asphalt product for protective coating of the present invention.

Embodiment 3

[0030] Take by weighing 30 parts of No. 100 straight run bitumen (penetration is 105) (by weight, the same below), 20 parts of octadecyl dimethyl benzyl ammonium chloride, 10 parts of fatty acid methyl ester polyoxyethylene ether, 12 parts of sodium carboxymethyl cellulose, 15 parts of isobutyl acrylate, and 60 parts of water. The above-mentioned asphalt is heated to 140°C, and then the above-mentioned other raw materials are prepared into a 50°C aqueous solution, and then the asphalt and the aqueous solution are passed through an emulsification device to obtain the emulsified asphalt product for protective coating of the present invention.

Abstract

The invention discloses emulsified asphalt for a protective coating, which comprises the following raw materials in parts by weight percent: 30-55 parts of asphalt, 10-20 parts of octadecyl dimethyl benzyl ammonium chloride, 5-10 parts of fatty acid methyl ester ethoxylate, 5-12 parts of sodium carboxymethyl cellulose, 8-15 parts of isobutyl acrylate and 20-60 parts of water. The emulsified asphalt of the invention is used as a protective coating of metal, can form a compact coated film, increases the shielding performance of the emulsified asphalt coating on a metal matrix and further improves the corrosion resisting property of the emulsified asphalt coating; and the invention has simple manufacturing method, easily-obtained raw materials and small environment pollution.

Description

technical field [0001] The invention relates to an emulsified asphalt, in particular to an emulsified asphalt used for protective coating. 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 the asphalt and shearing it at a high speed. 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 prevent steel corrosion. ...
