Abstract

The invention relates to the technical field of waterproof coiled materials, and provides a modified asphalt waterproof coiled material with a self-adhesive layer, wherein the modified asphalt waterproof coiled material comprises a polyethylene film, a modified asphalt coating material layer, a silica gel modified asphalt fully-impregnated polyester base layer, a modified asphalt coating material layer, a multi-layer casting co-extrusion film, a high-molecular hot-melt pressure-sensitive adhesive layer and a polyethylene isolating film which are arranged in sequence. By means of the technical scheme, the problems that in the prior art, the service life is short, and the mechanical property is poor are solved.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to a modified asphalt waterproof coiled material with a self-adhesive layer and a preparation method thereof. Background technique [0002] The modified asphalt root puncture-resistant waterproofing membrane for planting roofs is commonly used as copper-based modified asphalt waterproofing membrane and chemical root-blocking waterproofing membrane. SBS modified asphalt waterproofing membrane prepared by using composite copper base as the base The mechanism of root resistance is physical root resistance, which prevents the growth of plant roots through the barrier effect of the copper base, but because the copper base at the overlapping position cannot be overlapped, only the rubber materials are bonded together, this physical resistance Root coils will have defects at the overlapping locations. [0003] According to JGJ155-2013 "Technical Regulations for Planting...
