Problems solved by technology

When the modified asphalt membrane is exposed for a long time, the mineral particles on the surface are easy to fall off, and the modified asphalt is easy to age, resulting in a large number of cracks or cracks on the surface of the waterproof layer, which affects the waterproof function and the service life of the material
In addition, in order to improve the construction progress and bonding effect, the construction temperature is generally above 200°C, and volatile gas overflows during the construction process, which affects the air environment quality and personal safety. To a certain extent, it also leads to the reduction of waterproof life.

Abstract

The invention discloses an elastomer modified asphalt waterproof coiled material. The elastomer modified asphalt waterproof coiled material is characterized in that glassfiber felt or polyester felt serves as a reinforcing body, the upper face of the reinforcing body is coated with a modified asphalt layer, the upper surface of the modified asphalt layer is coated with a mineral particle layer, and the lower face of the reinforcing body is coated with a polyethylene film; a modified asphalt sizing material layer is arranged between an upper coating face layer and a middle carcase layer; and the modified asphalt sizing material layer is composed of the following raw materials of, by weight, 50-62 parts of asphalt, 8-10 parts of SBS synthetic rubber, 15-25 parts of granular paraffin, 1.5-2.5parts of polypropylene resin. The elastomer modified asphalt waterproof coiled material is long in service life and good in waterproof performance and aging resistant performance.

Description

technical field [0001] The invention belongs to the field of chemical materials for construction, and in particular relates to an elastomer-modified asphalt waterproof coiled material. Background technique [0002] Elastomer-modified asphalt waterproofing membrane plays an extremely important role in building waterproofing engineering. It is widely used in the waterproofing of the ground, underground and other special structures of buildings. It is a wide-ranging and large-scale waterproofing material. When the modified asphalt membrane is exposed for a long time, the mineral particles on the surface are easy to fall off, and the modified asphalt is easy to age, resulting in a large number of cracks or cracks on the surface of the waterproof layer, which affects the waterproof function and the service life of the material. In addition, in order to improve the construction progress and bonding effect, the construction temperature is generally above 200°C, and volatile gas ove...
