Abstract

The invention belongs to the field of building materials, and provides a waterproof hard asphalt material. The waterproof hard asphalt material comprises the following raw materials in parts by weight: 30-40 parts of petroleum asphalt, 5-10 parts of phenolic resin, 5-10 parts of diacetone acrylamide, 1-3 parts of p-hydroxybenzenesulfonic acid, 1-3 parts of polyoxypropylene glycerol ether, 1-3 parts of a stearate and 1-3 parts of acetone. The advantage of waterproofness of common waterproof asphalt is kept, and meanwhile, compressive strength of the material is improved, so that the compressionresistance is good. The texture is uniform and stable, the waterproof hard asphalt material can be used at an environment temperature of 25-40 DEG C, the hardness is moderate, and construction is facilitated.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a waterproof hard asphalt material. Background technique [0002] Asphalt is an indispensable material in civil engineering. It is widely used in construction, highway, bridge and other projects. Asphalt waterproof coatings are solvent-based or water-emulsion waterproof coatings based on asphalt. Solvent-based asphalt waterproof coatings are prepared by directly dissolving unmodified petroleum asphalt in gasoline and other solvents. Water-emulsified asphalt waterproof coating refers to the coating composed of petroleum asphalt dispersed in water under the action of chemical emulsifier or mineral emulsifier to form a stable water dispersion. However, ordinary asphalt materials have low hardness and poor compressive performance, and are prone to deformation due to the influence of ambient temperature. Contents of the invention [0003] The purpose of the present i...
