Abstract

The invention discloses an asphalt phenolic waterproof material. The asphalt phenolic waterproof material comprises the following components in parts by mass: 100 parts of petroleum asphalt, 10-25 parts of pine tar, 15-20 parts of ester gum, 1-2 parts of calcium chloride, 12-18 parts of rosin modified phenolic resin, 20-30 parts of pigment, 40-60 parts of solvent gasoline, 10-18 parts of aluminium paste, 30-40 parts of benzene, 6-8 parts of silicon dioxide, 8-10 parts of dimethylbenzene, 1-2 parts of butanol and 2-3 parts of ethanediamine; the product is excellent in corrosion resistance and has resistance to microbial corrosion; the time for surface drying is 2.2-3.2 hours; the time for hard dry is 20-22 hours; the asphalt phenolic waterproof material is high-temperature resistant and cold-resistant, has resistance to low temperature of 50 DEG C below zero and is incapable of defoaming and flowing within 4 hours at the temperature of 100-120 DEG C; the asphalt phenolic waterproof material is excellent in waterproof property, impermeable under 0.1-0.2MPa and excellent in anti-cracking property; and the product is high in bending resistance, excellent in weather resistance, high in compressive strength, applicable to extensive production and capable of continuously replacing the current material.

Description

technical field [0001] The application belongs to the field of asphalt waterproof materials, in particular to an asphalt phenolic waterproof material. Background technique [0002] Bitumen is a product of crude oil processing. It is a black or dark brown viscous liquid or solid at room temperature. It mainly contains soluble trichlorethylene hydrocarbon derivatives. Its properties and composition vary with sources and production methods. Variety. Like petroleum, asphalt is a complex organic mixture without fixed chemical composition and physical constants, and many oil minerals form a continuous series in transitional form. This brings many difficulties to classification and identification. Asphalt is a product of crude oil processing. It is a black or dark brown viscous liquid or solid at room temperature. It is a brown-black organic gelatinous substance, including natural asphalt, petroleum asphalt, shale asphalt and coal. Tar pitch and other four. The main components ...
