DETAILED DESCRIPTION
[0018] The present application will be further described in detail below with reference to the accompanying drawings.
[0019] The embodiment of the present application discloses a root-penetration-resistant waterproof roll material. Referring to Figure 1 , the root-penetration-resistant waterproof roll material comprises a base layer 1, a modified asphalt layer, a non-woven fabric layer, an aluminized film layer 6, a fire-retardant coating 7, an elastic connecting layer 8, and an isolation layer 9.
[0020] The base layer 1 adopts a copper foil base layer 1, which serves as the main base of the root-penetration-resistant waterproof roll material and has the function of physically resisting roots, so that the root resistance and puncture resistance of the waterproof roll material can be greatly improved.
[0021] The modified asphalt layer includes an upper modified asphalt layer 2 and a lower modified asphalt layer 3, which are arranged on the upper and lower sides of the base layer 1. The modified asphalt layer is composed of modified asphalt, which is used to meet the waterproofing requirements of the root penetration resistant waterproofing membrane and structurally enhances the ductility and puncture and tear resistance of the base layer 1.
[0022] The non-woven fabric layer includes an upper non-woven fabric layer 4 and a lower non-woven fabric layer 5, which are bonded to the side of the upper modified asphalt layer 2 and the lower modified asphalt layer 3 away from the base layer 1. The non-woven fabric layer is made of polypropylene filament non-woven fabric, which can increase the surface roughness, improve the bonding and laying performance, increase the mechanical strength, and improve the root penetration resistance of the waterproofing membrane and reduce damage to the base layer 1 caused by external factors.
[0023] The aluminized film layer 6 is bonded to the side of the upper non-woven fabric layer 4 away from the base layer 1, and the fire-retardant coating layer 7 is coated on the surface of the aluminized film layer 6. The fire-retardant coating layer 7 can be a polyurethane fire-retardant coating layer 7. The aluminized film layer 6 and the fire-retardant coating layer 7 provide the root penetration resistant waterproofing membrane with fire-retardant and heat-insulating effects.
[0024] The elastic connecting layer 8 is bonded to the side of the lower non-woven fabric layer 5 away from the base layer 1. The elastic connecting layer 8 is made of SBS thermoplastic elastomer, which has good waterproofness, extrusion resistance, and impact resistance, and can effectively improve the service life of the root penetration resistant waterproofing membrane.
[0025] The isolation layer 9 is bonded to the side of the elastic connecting layer 8 away from the base layer 1, which can protect the building roof during the laying of the root penetration resistant waterproofing membrane.
[0026] The base layer 1, the modified asphalt layer, the non-woven fabric layer, the aluminized film layer 6, and the fire-retardant coating layer 7 of the root penetration resistant waterproofing membrane constitute the main body of the root penetration resistant waterproofing membrane. The elastic connecting layer 8 extends upward from the length side to form a connecting piece 81, making the cross section of the elastic connecting layer 8 U-shaped. The elastic connecting layer 8 wraps the main body of the root penetration resistant waterproofing membrane inside through the connecting piece 81.
[0027] The side of the connecting piece 81 facing the main body of the root penetration resistant waterproofing membrane is provided with a sawtooth surface, and the corresponding surface of the main body of the root penetration resistant waterproofing membrane is also roughened to make the connecting piece 81 tightly adhere to the main body of the root penetration resistant waterproofing membrane, effectively increasing the contact area between the two. In this way, the connecting piece 81 can be more tightly adhered to the main body of the root penetration resistant waterproofing membrane through the adhesive, reducing the bonding gap between the two and avoiding water leakage.
[0028] Two connecting pieces 81 are set as connecting parts on the side away from the root penetration resistant waterproofing membrane body, one of which is horizontally provided with a boss 82, and the other is provided with a groove 83 matched with the boss 82, and the groove 83 is provided with an electric heating wire group 84 on the groove wall. When the root penetration resistant waterproofing membrane is laid, the boss 82 of the end of the adjacent root penetration resistant waterproofing membrane is just embedded into the groove 83 of the end of the other root penetration resistant waterproofing membrane, and then the electric heating wire group 84 is heated to make the two ends of the root penetration resistant waterproofing membrane embedded together hot melt into one, avoiding the problem of excessive adhesive accumulation in the current root penetration resistant waterproofing membrane joint, making the surface of the root penetration resistant waterproofing membrane joint more flat and beautiful, while ensuring the connection strength, and the electric heating wire group 84 arranged at the joint constitutes a metal barrier net and has the physical root blocking effect, which can greatly improve the root blocking and penetration resistance of the waterproofing membrane.
[0029] The specific embodiments are only an explanation of the present application, and are not a limitation of the present application, and those skilled in the art can make modifications to the embodiments without creative contribution according to the needs after reading the present specification, but as long as the scope of the claims of the present application is within the scope of the patent law.
