Abstract

The invention discloses a modified asphalt waterproof coating material, which is prepared from the following raw materials in parts by weight: 100-120 parts of modified asphalt emulsion, 25-30 parts of butadiene styrene rubber, 10-13 parts of desulfurization powder, 20-25 parts of a softener, 10-15 parts of a tackifier, 5-8 parts of a plasticizer, 25-30 parts of a thickener and 3-5 parts of a defoamer. In a waterproof coating material preparation process, the modified asphalt emulsion is prepared, wherein through montmorillonite and carbon nanotubes, the phase angle of asphalt is increased, the complex modulus is increased, the rutting factor is increased, and the high-temperature rutting resistance of the asphalt is improved, so that the high-temperature rutting resistance of the asphaltis further improved, the thermal aging resistance of the waterproof coating material is improved, and the aging resistance of the waterproof coating material is improved due to the fact that the montmorillonite and the carbon nanotubes have good aging resistance,.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to a modified asphalt waterproof paint. Background technique [0002] Asphalt is a brown or dark brown organic gelling material. It is an indispensable material in civil engineering construction. It is widely used in construction, highways, bridges and other projects. Asphalt waterproof coating is a solvent based on asphalt. Type or water-emulsion type waterproof coating, solvent-type asphalt waterproof coating refers to the configuration of unmodified petroleum asphalt directly dissolved in gasoline and other solvents, also known as cold base oil, water-emulsion type asphalt waterproof coating refers to the petroleum asphalt Under the action of chemical emulsifier or mineral emulsifier, asphalt is dispersed in water to form a stable water dispersion coating. [0003] The existing asphalt waterproof coating is oxidized after being used for a long time, and the coating f...
