Modified asphalt waterproof membrane for construction

Abstract

The invention discloses a modified bituminous waterproof roll for a building. The modified bituminous waterproof roll comprises a modified bituminous waterproof roll main body, wherein a protective film is arranged on the outer surface of the modified bituminous waterproof roll main body, binding tapes are arranged at the upper and lower ends of the outer surface of the protective film, a supportshaft roller is arranged in the middle of the modified bituminous waterproof roll main body, an isolation layer is arranged on the modified bituminous waterproof roll main body, an autohension modified bituminous size layer is arranged on the upper end surface of the isolation layer, a fourth elastomer bituminous size layer is arranged on the other side of the upper end surface of the autohensionmodified bituminous size layer, a second padding layer is arranged on the upper end surface of the fourth elastomer bituminous size layer, and a first padding layer is arranged on the upper end surface of a third elastomer bituminous size layer. The problem that hollowing occurs easily during laying because the residual isolation film remains on the surface during laying and affects the waterprooffunction of the roll is solved.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a modified asphalt waterproof coiled material for construction. Background technique [0002] The modified asphalt waterproofing membrane is made of SBS rubber modified petroleum asphalt as the impregnated covering layer, made of polyester fiber non-woven fabric, jute cloth, glass fiber mat, etc. as the base, and plastic film as the anti-stick isolation layer , processed through material selection, ingredients, co-melting, impregnation, composite molding, curling and other processes. This kind of coil has good high temperature resistance and can be used in the temperature range of -25 to +100°C. It has good low temperature flexibility and does not crack when the temperature reaches -25°C. It has high heat resistance and the temperature reaches 90. It does not flow at ℃, has high elasticity and fatigue resistance, as well as up to 1500% elongation, strong puncture resis...
