Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a high-temperature resistant and high-adhesive self-adhesive polymer modified asphalt waterproof coiled material. Background Art

[0002] Waterproofing membrane is mainly used in building walls, roofs, tunnels, roads, landfills and other places. It is a flexible building material product that can be rolled into a roll to resist leakage from external rainwater and groundwater. As a leak-free connection between the engineering foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. With the continuous development and replacement of waterproofing membranes, the functionality of waterproofing membranes is becoming more and more diverse.

[0003] In the prior art, the thermal insulation structure of the waterproof membrane is often at its top layer, and such thermal insulation structure is often not provided with an auxiliary heat-absorbing structure, resulting in the heat that cannot be blocked by the thermal insulation structure being transferred to the bonding surface of the waterproof membrane. Over time, it is very likely to cause multiple bulges on the bonding surface of the waterproof membrane. Secondly, the waterproof membrane on the market is mainly connected to the building through the bottom adhesive layer. Since the waterproof membrane itself does not have the function of storing glue and secondary gluing, there is a risk of the waterproof membrane falling off after the adhesive material of the adhesive layer ages and fails.

[0004] To this end, a high-temperature resistant and high-adhesion self-adhesive polymer modified asphalt waterproofing membrane is proposed, which has the advantages of high-temperature resistance and high adhesion, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a high-temperature resistant and high-adhesive self-adhesive polymer modified asphalt waterproofing membrane.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-temperature resistant and high-adhesive self-adhesive polymer modified asphalt waterproof membrane, comprising a waterproof membrane body, a tire base is arranged inside the waterproof membrane body, and a plurality of rubber storage strips are embedded and installed on the bottom surface of the tire base, and the bottom surface of the tire base is covered with a polymer modified asphalt self-adhesive layer, an isolation layer is bonded to the top surface of the tire base, and a waterproof layer is bonded to the top surface of the isolation layer, a heat absorption layer is bonded to the top surface of the waterproof layer, and the heat absorption layer is composed of a plurality of interconnected heat absorption bags, and each heat absorption bag of the heat absorption layer is filled with ceramic filler, a high-temperature resistant layer is arranged on the top surface of the waterproof membrane body, and the bottom surface of the high-temperature resistant layer is bonded to the top surface of the heat absorption layer, the rubber storage strip is filled with glue, and a glue leakage port is opened on the bottom surface of the rubber storage strip, and a degradable film is bonded to the periphery of the glue leakage port.

[0007] As a further description of the above technical solution: the interior of the rubber storage strip is filled with two pieces of filling cotton, and the two pieces of filling cotton are symmetrical about the vertical center line of the rubber leakage port.

[0008] As a further description of the above technical solution: the lengths of the heat absorption bag and the rubber storage strip are the same as the width of the waterproof membrane body.

[0009] As a further description of the above technical solution: the ceramic filler filled in the heat absorption bag is an elliptical structure.

[0010] As a further description of the above technical solution: the high temperature resistant layer adopts a thermoplastic styrene-butadiene rubber mixture.

[0011] As a further description of the above technical solution: the isolation layer is made of thermal insulation film material, and the waterproof layer is made of high-density polyethylene or ethylene-vinyl acetate copolymer.

[0012] As a further description of the above technical solution: the glue leakage port is in a strip-shaped structure, and the degradable membrane is in a belt-shaped structure corresponding to the glue leakage port.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, a high-temperature resistant structure of a waterproof membrane is formed by a high-temperature resistant layer, a heat-absorbing layer and an insulating layer. The high-temperature resistant layer arranged on the top surface of the waterproof membrane body isolates most of the heat generated by sunlight, and the heat penetrating the high-temperature resistant layer is transferred to the heat-absorbing layer. Since the heat-absorbing layer is composed of a plurality of heat-absorbing bags filled with elliptical ceramic fillers, the purpose of heat absorption is achieved according to the heat absorption characteristics of the ceramic fillers. Since a waterproof layer and an insulating layer are arranged below the heat-absorbing layer, the insulating layer made of a heat-insulating film material blocks the heat transferred to the insulating layer, and prevents the heat from continuing to be transferred to the lower part of the waterproof membrane body, thereby significantly improving the high-temperature resistance. A plurality of rubber storage strips are embedded and installed on the bottom surface of the tire base, and the rubber leakage port at the bottom of the rubber storage strip is connected to the polymer modified asphalt self-adhesive layer. Under the action of external force extrusion or natural degradation, the degradable film attached to the periphery of the rubber leakage port loses the state of sealing the rubber leakage port, so that the glue filled in the rubber storage strip flows out, so as to further enhance the reliability of the bonding of the waterproof membrane body on the basis of the polymer modified asphalt self-adhesive layer.

The material of the heat absorption bag 8 can be selected from silica gel or pp film to prevent rupture;

[0023] In one embodiment, the rubber storage strip 10 is filled with two pieces of filling cotton 11, and the two pieces of filling cotton 11 are symmetrical about the vertical center line of the glue leakage port 12. Through the setting of the filling cotton 11, a certain degree of support can be provided after the glue liquid completely flows out, thereby avoiding the collapse of the surface of the waterproof roll material body 1.

[0024] In one embodiment, the lengths of the heat absorption bag 8 and the rubber storage strip 10 are the same as the width of the waterproof membrane body 1. Through the setting of the heat absorption bag 8, the transferred heat can be absorbed. Through the setting of the rubber storage strip 10, if there is a bulge at any position of the waterproof membrane body 1, the glue can be squeezed and released through the rubber storage strip 10 to compensate the bonding surface of the waterproof membrane body 1 with glue, thereby ensuring the bonding effect of the waterproof membrane body 1.

[0025] In one embodiment, the ceramic filler 9 filled in the heat absorption bag 8 is an elliptical structure. The ceramic filler 9 with an elliptical structure makes the overall structure more uniform and less prone to breakage.

Since the waterproof layer 6 and the isolation layer 7 are arranged below the heat absorption layer 5, the isolation layer 7 made of the thermal insulation film material blocks the heat transferred to the isolation layer 7, thereby preventing the heat from continuing to be transferred to the lower part of the waterproof coiled material body 1 In order to improve the high temperature resistance of the waterproof membrane body 1, a plurality of rubber storage strips 10 are embedded and installed on the bottom surface of the tire base 2, and the glue leakage port 12 at the bottom of the rubber storage strip 10 is connected with the polymer modified asphalt self-adhesive layer 3. Under the action of external force or natural degradation, the degradable membrane 13 attached to the outer periphery of the glue leakage port 12 loses the state of sealing the glue leakage port 12, so that the glue filled in the rubber storage strip 10 flows out, so as to further enhance the reliability of the bonding of the waterproof membrane body 1 on the basis of the polymer modified asphalt self-adhesive layer 3.
