Abstract

The invention provides an asphalt rubber material for producing an SBS elastomer modified asphalt waterproof roll material. The asphalt rubber material is prepared from the following main raw materials in percentage by mass: 60-75% of asphalt, 5-20% of rubber, 5-15% of petroleum resin and/or coumarone resin, 10-25% of softening oil and 1-5% of a stabilizer. The asphalt rubber is high in ductility, softening point and needle penetration. When the asphalt rubber is used for preparing SBS elastomer modified asphalt waterproof roll material, the low-temperature flexibility, high-temperature resistance, cohesive strength and waterproof performance of the waterproof roll material can be improved; the waterproof roll material shows excellent waterproof performance; the energy loss, the material loss, the labor cost and the production cost can be reduced; and the quality is very easy to control.

Description

technical field [0001] The invention belongs to the technical field of waterproof membranes, and relates to an asphalt rubber material for producing SBS elastomer modified asphalt waterproof membranes, a preparation method and application thereof. Background technique [0002] Asphalt is a product of crude oil processing. It is a black or dark brown viscous liquid or solid at room temperature, including natural asphalt, petroleum asphalt, shale asphalt and coal tar asphalt. The main components of asphalt are asphaltene and resin, followed by high boiling point mineral oil and a small amount of oxygen, sulfur and chlorine compounds. Asphalt is in a glossy semi-solid state, brittle at low temperature, and has good cohesiveness, waterproof performance and anti-corrosion performance. It has been widely used in the fields of roads, waterproof engineering and anti-corrosion. However, due to the poor performance of asphalt in terms of high temperature resistance, fluidity resistan...
