Abstract

The invention belongs to the technical field of architectural waterproof materials, and discloses a waterproof material prepared from fluid rubber. The preparation method comprises the following steps: heating an organic solvent for dehydration, adding fluid rubber and an antioxidant, and dissolving by heating; and cooling, adding a liquid resin, petroleum asphalt, a reinforcer and an organic activating agent, dissolving, finally adding mixed ore powder and sodium silicate, dissolving, and cooling to obtain the waterproof material. The waterproof material obtained by the technique enables concrete and the coiled material to be compactly embedded into an integral body, and enhances the properties of the concrete; the waterproof material has the advantages of heat resistance and no cracking, has the air-permeable functions of water seepage resistance and perspiration discharge like human skin, and has superhigh healing capacity for fine cracks.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and relates to a waterproof material made of liquid rubber used in construction joints and connection joints formed between engineering concrete or between concrete and steel bars and other media and a preparation method thereof. Background technique [0002] At present, most of the waterproof membranes on the market are modified materials based on base asphalt. Asphalt is easy to be brittle at low temperature and easy to flow at high temperature. Although the performance of the modified material has been greatly improved, as time goes by, a part of the modifier added (such as: waste engine oil, etc.) migrates and precipitates, and the viscosity performance index of the material will be greatly reduced. At present, the building life stipulated by the state is 70 years, while the life of first-class building waterproof materials is only 25 years. That is, the life of buil...
