Abstract

The invention discloses waterproof mortar of asphalt and a preparation method of the waterproof mortar. The waterproof mortar of the asphalt comprises a component A and a component B, wherein the component A is emulsified asphalt; the component B is prepared from the following raw materials in parts by weight: 50-70 parts of cement, 10-30 parts of packing and 1-5 parts of an adjuvant. The waterproof mortar of the asphalt has excellent adhesiveness and self-healing property, so that the protected object is completely sealed without a gap; and the waterproof mortar can resist corrosion of low-concentration inorganic acids, alkalis and salts, ultraviolet ray and biodegradation, has excellent anti-stripping ability, good softness, and excellent characteristics of being non-toxic, tasteless, free of pollution and the like, and is excellent in application property and low in price. The waterproof mortar of the asphalt can be used as a coating waterproof layer, and is applied to basements of buildings, road and bridge decks, tunnels and the like.

Description

technical field [0001] The invention relates to a waterproof mortar and a preparation method thereof, in particular to an asphalt waterproof mortar and a preparation method thereof. Background technique [0002] Asphalt is a mixture of various polymers with complex chemical composition. It has unique rheological properties. Because of its good adhesion, aging resistance and waterproof ability, it has been widely used in waterproof and sealing materials, roads for a long time patching etc. As a traditional waterproof material, it has the advantages of wide material sources, low price, and resistance to low-concentration inorganic acids, alkalis and salt corrosion, which makes asphalt still have a huge application market. [0003] At present, cement mortar is not resistant to water, requires maintenance, and is prone to cracking and other problems. Adding bitumen to the mortar increases the resistance to cracking and improves the water resistance of the product. At present,...
