SBS elastomer modified asphalt waterproof coiled material

Abstract

The invention discloses an SBS elastomer modified asphalt waterproof coiled material which comprises a winding drum and a cutting strip, a polyethylene melting film is wound on the outer surface of the winding drum, and first elastomer modified asphalt is mounted at the top of the polyethylene melting film; a non-woven fabric is mounted at the top of the first elastomer modified asphalt, an activated carbon fiber layer is mounted at the top of the non-woven fabric, convex blocks are mounted at four corners of the top of the activated carbon fiber layer, a heat insulation pad is mounted at the top of the activated carbon fiber layer, and insertion holes are formed in four corners of the top of the heat insulation pad in a penetrating manner; the heat insulation pad is of a hollow structure, interlayers are installed on the inner walls of the two sides of the heat insulation pad, and the interlayers are filled with evenly-arranged heat insulation particles. By arranging the winding drum, the activated carbon fiber layer, the heat insulation pad and the heat insulation particles, in the hot melting process, the activated carbon fiber layer can adsorb peculiar smell generated during hot melting, and the heat insulation performance of the waterproof roll is improved through the heat insulation pad and the heat insulation particles.

Description

technical field [0001] The invention relates to the technical field of bitumen waterproofing membranes, in particular to an SBS elastomer-modified bitumen waterproofing membrane. Background technique [0002] SBS elastomer-modified bitumen waterproofing membrane is based on polyester felt or glass fiber felt as the base, with styrene-butadiene-styrene copolymer thermoplastic elastomer as modifier, and both sides are covered with mineral particles such as polyethylene film. The modified bitumen waterproofing membrane is made of modified asphalt waterproofing membrane, and the asphalt waterproofing membrane usually needs to use a hot-melt tool to bake the lower surface of the membrane when laying, but the existing asphalt waterproofing membrane has poor thermal insulation performance , it is easy to affect the use of subsequent coils due to baking during paving. Therefore, an SBS elastomer-modified asphalt waterproofing membrane with good heat insulation effect is urgently nee...

AI Technical Summary

Problems solved by technology

The pre-paved SBS modified bitumen waterproof coiled material used in engineering provided by the utility model has the advantages of good aging resistance, long service life, convenient laying, and can reduce the labor intensity of construction and laying personnel. However, in the above-mentioned open documents The SBS elastomer modified asphalt waterproofing membrane mainly considers how to improve its own service life and practical performance, and does not consider that the existing asphalt waterproofing membrane does not have heat insulation function;

[0005] 2. The patent document CN211366610U provides an asphalt waterproof membrane, including a waterproof membrane body, a mounting plate, a fixed frame, a moving wheel, a pulling plate, a tension spring, a clamping round table, a mounting frame, an adjustment rod and a connecting plate, and the asphalt A mounting plate is installed on the lower side of the main body of the waterproof membrane, a fixed frame is fixed on the lower end of the mounting plate, a moving wheel is installed on the inner side of the fixed frame, a mounting frame is installed on the front and rear sides of the upper end of the mounting plate, and an adjusting pull rod is connected to the front side of the mounting frame. There is a tension spring on the front sleeve of the ring side of the adjusting rod, a pulling plate is fixed on the front end of the adjusting rod, a connecting plate is fixed on the rear end of the adjusting rod, and a clamping round table is connected to the ring side of the connecting plate. However, the utility model has a reasonable structure, is convenient for assembly and installation, is simple and convenient for laying, and has a good use effect. However, the SBS elastomer modified asphalt waterproofing membrane in the above-mentioned open documents mainly considers how to quickly and conveniently waterproof The assembly and laying of the membrane did not take into account that the existing asphalt waterproof membrane is easy to cause asphalt overflow during the laying process and affect the subsequent laying effect;

In the present utility model, the body of the asphalt waterproof coiled material modified by the elastomer, the overlapping reference line, the base layer, the heat insulation protective layer and the anti-aging protective layer can be used to overlap the reference line and locate the coiled material. However, in the above-mentioned open documents The SBS elastomer modified asphalt waterproofing membrane mainly considers how to accurately position the asphalt waterproofing membrane, and does not take into account that the edges of the existing asphalt waterproofing membrane are easily eroded by rainwater, thereby reducing the waterproof effect
