Abstract

The invention discloses a self-adhesive polymer modified asphalt waterproof coiled material. According to the self-adhesive polymer modified asphalt waterproof coiled material, glass fiber felt or polyester felt serves as a reinforcer, the upper face of the reinforcer is coated with a modification asphalt layer, the upper surface of the modification asphalt layer is coated with a mineral particlelayer, and the lower face of the reinforcer is coated with a thermoplastic polyolefin layer; a modified asphalt mastic layer is arranged between an upper cover layer and an middle body layer; and themodified asphalt mastic layer is prepared from the following raw materials in parts by weight: 50-62 parts of asphalt, 8-10 parts of SBS synthetic rubber, 15-25 parts of waste rubber powder and 1.5-2.5 parts of polypropylene resin. The waterproof coiled material disclosed by invention is long in service life and good in waterproof performance and aging resistance.

Description

technical field [0001] The invention belongs to the field of chemical materials for construction, and in particular relates to a self-adhesive polymer modified asphalt waterproof coiled material and a preparation method thereof.
