[0031] The following is combined with Figure 1-Figure 3 This application is described in further detail.
[0032] The utility model discloses a coating-rolling combined polymer waterproofing coiled material, such as Figure 1 and Figure 2As shown, it includes a protective layer 1, which is a wear-resistant rubber layer. A waterproof layer 11 is bonded below the protective layer 1, and the waterproof layer 11 is a polyethylene film. A plurality of fixing strips 12 are evenly arranged between the waterproof layer 11 and the protective layer 1. The cross-section of the fixing strips 12 is square and is arranged along the width direction of the waterproof layer 11. A first adhesive layer 13 is arranged below the waterproof layer 11, and the first adhesive layer 13 is a non-asphalt pressure-sensitive adhesive layer. A first isolation film 14 is bonded below the first adhesive layer 13, and the length of the first isolation film 14 is longer than that of the waterproof layer 11, and the first isolation film 14 is a polyolefin film.
[0033] When it is necessary to lay the polymer waterproof membrane, the operator first separates the first isolation film 14 from the first adhesive layer 13, and then bonds the first adhesive layer 13 to the base surface. Through the setting of the fixing strips 12, when the operator is laying the membrane flat, adjacent fixing strips 12 can provide interaction force, which can facilitate the flattening of the membrane between two adjacent fixing strips 12, thereby reducing the possibility of overlapping of the membrane, and then facilitating the neat laying of the polymer waterproof membrane. Through the setting of the protective layer 1, the waterproof layer 11 can be protected, thereby reducing the possibility of damaging the waterproof layer 11 when working on the waterproof layer 11.
[0034] like Figure 2 and Figure 3 As shown, a coating layer 15 is provided between the first adhesive layer 13 and the waterproof layer 11, and the polypropylene waterproof coiled material is immersed in the waterproof coating, and the waterproof coating particles are adsorbed on the surface of the polypropylene waterproof coiled material, thereby obtaining the coating layer 15. When the base surface needs to be waterproofed, the requirements of engineering waterproofing can be easily met under the dual protection of the coating layer 15 and the waterproof layer 11.
[0035] like Figure 2 and Figure 3 As shown, a second adhesive layer 16 is provided between the protective layer 1 and the waterproof layer 11. The second adhesive layer 16 is a non-asphalt pressure-sensitive adhesive layer, and the fixing strip 12 is provided inside the second adhesive layer 16. When the operator lays the coiled material, the second adhesive layer 16 can reduce the possibility of the fixing strip 12 moving, and at the same time, the protective layer 1 and the waterproof layer 11 are bonded together, so as to reduce the possibility of the protective layer 1 and the waterproof layer 11 being separated under the influence of external factors.
[0036] like Figure 2As shown, a plurality of slots 17 are evenly provided along the length direction on the first adhesive layer 13, and the cross section of the slots 17 is square and extends along the vertical direction. After the coiled material is laid, the slots 17 are provided to reduce the area where the coating layer 15 is attached to the base layer, so that when the base layer breaks and cracks occur, the possibility of the coiled material breaking under the stress of the base layer can be reduced, thereby improving the waterproofness of the coiled material.
[0037] like Figure 2 and Figure 3 As shown, the side wall of the protective layer 1 is evenly provided with a plurality of partition grooves 18 along the length direction and the width direction, and the partition grooves 18 extend along the vertical direction and penetrate the protective layer 1. When the operator needs to cut the coil, the provision of the partition grooves 18 facilitates the operator to cut along the direction of adjacent partition grooves 18.
[0038] like Figure 1 and Figure 2 As shown, the side wall of the protective layer 1 is provided with a winding core tube 21, the cross section of the winding core tube 21 is circular and is arranged along the width direction of the protective layer 1. When the operator winds the coil on the winding core tube 21, the shape of the coil can be easily maintained, and then it can be easily transported.
[0039] like Figure 2 As shown, the side wall of the first isolation film 14 close to the coating layer 15 is provided with a third adhesive layer 19, the third adhesive layer 19 is square, the third adhesive layer 19 is a non-asphalt pressure-sensitive adhesive layer, and the side wall of the third adhesive layer 19 is bonded with a second isolation film 20, which is a polyolefin film. After the operator winds the coiled material onto the outer wall of the winding core tube 21, the second isolation film 20 is torn off, and then the third adhesive layer 19 is bonded to the side wall of the first isolation film 14, so that the coiled material can be easily fixed.
[0040] The implementation principle of a coating-coil-combined polymer waterproofing membrane in the present application embodiment is as follows:
[0041] When it is necessary to lay the polymer waterproof membrane, the operator first separates the first isolation film 14 from the first adhesive layer 13, and then bonds the first adhesive layer 13 to the base surface. Through the setting of the fixing strips 12, when the operator is laying the membrane flat, adjacent fixing strips 12 can provide interaction force, so that the membrane between two adjacent fixing strips 12 can be flattened, thereby reducing the possibility of overlapping of the membrane, and then facilitating the neat laying of the polymer waterproof membrane. Through the setting of the protective layer 1, the waterproof layer 11 can be protected, thereby reducing the possibility of damaging the waterproof layer 11 when working on the waterproof layer 11.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
