Abstract

The present invention discloses a weathering resistance modified asphalt waterproof coiled material, wherein a glass fiber felt or polyester felt is adopted as a reinforcement, a weathering resistance modified asphalt layer is coated on the upper surface of the reinforcement, a modified asphalt layer with the characteristic of easy hot melting is coated on the lower surface of the reinforcement, a mineral particle layer is covered on the upper surface of the weathering resistance modified asphalt layer, and a polyethylene film is covered on the lower surface of the modified asphalt layer with the characteristic of easy hot melting. According to the present invention, the weathering resistance modified asphalt waterproof coiled material has characteristics of long service life, high waterproof performance, low construction temperature, reduction of aging of the modified asphalt at the high temperature, and reduction of environment pollution, and can be used for industrial and civil building roofing waterproof projects at different temperatures in different regions.

Description

technical field [0001] The invention relates to a modified asphalt waterproof coiled material with good weather resistance, which belongs to the field of chemical materials for construction. Background technique [0002] Modified asphalt waterproofing membrane plays an extremely important role in building waterproofing engineering, and 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. The current specifications and varieties of modified asphalt waterproofing membranes have developed from a single asphalt felt in the 1950s to dozens of high and medium-grade membranes with different physical properties. [0003] In foreign countries, modified asphalt waterproofing membranes also occupy a dominant position in waterproofing membranes. At present, there are more than 200 specifications and varieties, such as asphalt-based waterproofing membranes in waterproof mater...
