The utility model is further configured as follows: there are multiple heat-insulation cavities, and they are evenly and horizontally spaced in the middle of the heat-insulation layer.

By adopting the above technical solution, after the heat insulation cavities are arranged at even intervals horizontally, the heat insulation effect of the heat insulation layer is more uniform.

The utility model is further configured as: the upper surface of the heat insulation layer is covered with an aluminum foil layer.

By adopting the above technical solution, the aluminum foil layer can reflect a part of sunlight, and at the same time, it can also prevent the dark rubber layer from absorbing a large amount of heat, and reduce the overall heat absorption of the waterproof coiled material.

The utility model is further set as follows: one side of the heat insulation layer is provided with a step-shaped overlapping surface, and the side of the heat insulation layer away from the overlapping surface is an overlapping portion that is overlapped and spliced with the overlapping surface, and the overlapping surface A glue layer is coated on the contact surface with the overlapping part, and the outer side of the glue layer is glued and covered with release paper.

By adopting the above technical scheme, when splicing waterproof membranes, after laying one of the waterproof membranes, the overlapping part of the other waterproof membrane is overlapped on the lapping surface of the laid waterproof membrane, Before splicing, the release paper is torn off, and the glue layer is used to bond the overlapping surface and the overlapping part to play the role of fixing and waterproofing.

The utility model is further configured as follows: the overlapping portion exceeds the side of the asphalt layer, and the side of the asphalt layer away from the overlapping portion exceeds the overlapping surface.

By adopting the above technical solution, after the overlapping portion and the overlapping surface are overlapped, the asphalt layers can also be spliced without interference.

The utility model is further configured as follows: the lower side of the overlapping part is dip-coated with an adhesive asphalt layer.

By adopting the above technical solution, the overlapping part can be bonded to the asphalt layer by using the adhesive asphalt layer, so as to ensure that the asphalt layers that mainly play a waterproof effect can be bonded and adhered to form a continuous waterproof layer.

In summary, the utility model has the following technical effects:

1. By adhering a thermal insulation layer made of thermal insulation rubber above the asphalt layer, and setting multiple thermal insulation holes in the thermal insulation layer, the thermal insulation performance of the waterproof membrane is improved;

2. By setting an aluminum foil layer on the outside of the heat insulation layer, the effect of reflecting sunlight on the waterproof membrane can be improved, and the light absorption performance of the waterproof membrane can be reduced.

Detailed ways

As shown in Figure 1, the utility model introduces a heat-insulating waterproof coiled material, which includes a base 1 made of polyester fiber cloth and an asphalt layer 2 dip-coated on the upper and lower sides of the base 1, and the asphalt on the top The top of the layer 2 is glued and covered with a heat insulating layer 3 made of heat insulating rubber, and the top of the heat insulating layer 3 is glued and covered with an aluminum foil layer 4 . When the waterproof membrane is laid on the roof, a part of the sunlight can be reflected by the aluminum foil layer 4, and the overall heat absorption performance of the waterproof membrane can be reduced, and the heat resistance of the waterproof membrane can be reduced from the root; 3. It can isolate the heat transferred on the aluminum foil layer 4, reduce the heat transferred from the aluminum foil layer 4 to the asphalt layer 2 through the heat insulation layer 3, thereby improving the heat insulation performance of the waterproof membrane.

As shown in FIG. 1 , a plurality of heat insulating cavities 31 are opened in the middle of the heat insulating layer 3 , and the heat insulating cavities 31 can further improve the heat insulating ability of the heat insulating layer 3 through the inner chambers. The heat insulation cavities 31 are horizontally and evenly spaced in the middle of the heat insulation layer 3 , so that the heat insulation effect of the heat insulation layer 3 is more uniform.

The waterproof membranes need to be spliced with each other. In order to ensure the stability and waterproofness of the spliced waterproof membranes at the seam position, as shown in Figure 1, one side of the heat insulation layer 3 is provided with a stepped lap The joint surface 36, the side of the heat insulation layer 3 away from the joint surface 36 is the lap joint 32 which overlaps with the lap joint 36, and the contact surfaces of the lap joint 36 and the lap joint 32 are coated with an adhesive layer 33, the outer side of the adhesive layer 33 is covered with release paper 34. When splicing waterproof membranes, after laying one of the waterproof membranes, the overlapping portion 32 of another piece of waterproof membrane is overlapped on the overlapping surface 36 of the waterproof membrane that has been laid, and the isolation is separated before splicing. The paper 34 is torn off, and the glue layer 33 is used to bond the overlapping surface 36 and the overlapping portion 32 to play the role of fixing and waterproofing.

As shown in Figure 1, the overlapping portion 32 exceeds the side of the asphalt layer 2, and the side of the asphalt layer 2 away from the overlapping portion 32 exceeds the overlapping surface 36, so that after the overlapping portion 32 and the overlapping surface 36 are overlapped, The asphalt layers 2 can also be spliced without interference.

As shown in Figure 1, after the lap joint 32 and the lap joint surface 36 are co-bonded, there is still a gap between the asphalt layers 2 between the two waterproof membranes. Long-term practical aging will easily cause water leakage at the asphalt layer 2 between two waterproof membranes. In order to solve the above problems, an adhesive asphalt layer 35 can be dip-coated on the underside of the overlapping portion 32, and the adhesive asphalt layer 35 and the asphalt layer 2 below it are bonded to each other, and the overlapping portion 32 utilizes the adhesive asphalt layer The layer 35 can be bonded with the asphalt layer 2, so as to ensure that the asphalt layers 2 that mainly play a waterproof role can be bonded and adhered to form a continuous waterproof layer.
