下記表に示す結果が得られた。 The present invention relates to a tarpaulin sheet used in waterproofing construction, and in particular, in this case, an adhesive is applied to the surface of the vulcanized rubber tarpaulin sheet in advance to facilitate bonding and integrating the vulcanized rubber tarpaulin sheet with other components. The present invention relates to a method for laminating heat-sealable films. Generally, when connecting tarpaulin sheets together, a heat sealing film is laminated to the edge of the vulcanized rubber tarpaulin sheet that will serve as the lap surface, and then the heat sealing film is laminated to the edge of the vulcanized rubber tarpaulin sheet. They were connected by sanding down comrades. Conventionally, a heat press or a T-die extruder has been used to laminate a heat-adhesive film onto a vulcanized rubber waterproof sheet, but these have the following drawbacks. Pressing method: Pressing is performed for each fixed length, so
Set-up, pressing and cooling are required, resulting in extremely low productivity.Furthermore, because of hot pressing, the flow becomes non-uniform, making it impossible to laminate a heat-sealable film over a certain width. T-die extruder method: Usually requires an expensive preheating device to preheat the vulcanized rubber tarpaulin sheet, which is the adherend, and because it laminates a heat-fused film heated to above the fusing temperature using an extruder,
Expensive extruders are required, and because they are large, they tend to take up space and are uneconomical. In addition, at construction sites for vulcanized rubber tarpaulin sheets, the sheets are usually cut to fit the ancillary equipment, but in this case, it is nearly impossible to carry heat presses or T-die extruders to the construction site, and Another drawback is that it is very difficult to laminate a heat-adhesive film to a cut portion of a vulcanized rubber tarpaulin sheet. In addition, vulcanized rubber waterproof sheets have poor thermal adhesion and are thicker than heat-adhesive films, resulting in large heat loss when heated with hot air. For this reason, when laminating a heat-adhesive film onto a vulcanized rubber tarpaulin sheet, it is necessary to raise the temperature of the hot air to a slightly higher temperature. There is a problem in that the adhesive film is thermally deformed, making it impossible to obtain a heat-fused film laminate vulcanized rubber waterproof sheet with a uniform and good appearance. The present invention has been made in view of the above, and its purpose is to eliminate the drawbacks of the prior art described above, and to easily attach one side of the connecting end of a vulcanized rubber tarpaulin sheet at a construction site. An object of the present invention is to provide a method for laminating a heat-fusion adhesive film onto a waterproof sheet, which can be laminated with a hot-melt adhesive film. The gist of this invention is to preheat a vulcanized rubber waterproof sheet from the non-laminated side with a hot plate, and then continuously apply a heat-sealable film on the preheated vulcanized rubber waterproof sheet. The pressing force is 2.5 while blowing hot air onto the joint surface of the two.
The method of laminating a heat-sealable film onto a waterproof sheet includes continuously laminating the heat-sealable film onto the vulcanized rubber waterproof sheet under pressure using a pressure roll of 1 cm or more per kilogram of film. That is, the method of laminating a heat-fused film to a vulcanized rubber tarpaulin sheet of the present invention has disadvantages of the conventional hot air heating lamination method, such as a decrease in adhesive strength due to the lack of heat retention and heat softening properties of the vulcanized rubber tarpaulin sheet, and In order to improve the deterioration of adhesive strength and appearance due to thermal deformation of the heat-sealable film due to overheating, the vulcanized rubber waterproof sheet is preheated from the non-laminated side with a hot plate in advance to prevent vulcanization. The heat retention and heat softening properties of the rubber tarpaulin sheet are maintained, and under these conditions, hot air is simultaneously blown onto the joint surface of the vulcanized rubber tarpaulin sheet and the heat-adhesive film, and a pressure roll of 2.5 kg/film 1 cm or more is further applied. The vulcanized rubber waterproof sheet and the heat-adhesive film are strongly bonded together by applying pressure. Hereinafter, an embodiment of the lamination method of the present invention will be described with reference to the drawings. Sulfur rubber waterproof sheet 1, 2
A large roll 4 for crimping is fixed between two play plates 3, a small roll 5 to maintain stable movement of the large roll 4, and a roll 7 on which a heat-sealing film 6 is wound are rotatably fixed. Prepare a pressure bonding roll 8 and a handheld hot air blower 9 with a replaceable nozzle and temperature control. First, place the edge of the vulcanized rubber waterproof sheet 1 on the hot plate 2, and then Preheat 1 to 100℃. in this case
Although the temperature was set at 100°C, the temperature of the surface of the vulcanized rubber waterproof sheet 1 is preferably heated to 60°C or higher, preferably 100°C or higher, in view of the adhesive properties of the heat-adhesive film 6. Next, when the temperature of the vulcanized rubber tarpaulin sheet 1 rises to an appropriate temperature, 2.5 kg/1 cm of film is placed on the heated plate 2 of the vulcanized rubber tarpaulin sheet 1.
A crimping roll 8 having a crimping force of . Further, a heat-sealing film is wound from the roll 7 to the heat-sealing film 6.
The tip of the vulcanized rubber waterproof sheet 1 is taken out and guided through the large roll 4 to the end of the vulcanized rubber waterproof sheet 1, and the vulcanized rubber waterproof sheet 1 and the heat-sealable film 6 are arranged so as to form a laminated part. 9 hot air (180
℃) is directly sprayed onto the vulcanized rubber waterproof sheet 1 and the heat sealing film 6 just before they are joined. By moving the pressure roll 8 at the same time as the melted portion is formed, the lamination of the heat sealing film 6 onto the vulcanized rubber waterproof sheet 1 is completed. In this case, it is desirable to use SUS material as the material for the pressure roll 8 , especially the large roll 4. In addition, in this example, the thickness of the heat-fused film is
Timer A4090 (manufactured by Mitsui Petrochemical Industries, Ltd.) film made of a 300 μm olefin thermoplastic resin was used, but the film is not limited thereto. The temperature of the hot air varies depending on the material of the heat-adhesive film, but it is usually desirable to have a temperature of 150°C or higher. In this example, the pressure roll 8 and the hot air blower 9 are prepared separately, and the pressure roll 8 is moved by holding the hot air blower 9 in the left hand of the worker and grasping the guide rod 10 with the right hand. Yes, but a crimp roll
A hot air blower 9 may be integrated into the hot air blower 8 , and in this case, it is possible to blow hot air at a constant temperature at all times. Next, the edges of the vulcanized rubber waterproof sheet laminated with the heat-fusible film obtained in this example were heated with hot air at 180°C, and then pasted so that the heat-fusible film surfaces overlapped. At the same time, the connecting part of the waterproof sheet is formed, and the adhesion strength test of the adhesive part is carried out using the above-mentioned example with a roll pressure of 1.5.
A laminate body obtained by changing the kg/film 1cm, 2.0kg/film 1cm, or 2.5kg/film 1cm, and a method other than this invention, that is, Toughmer on the vulcanized rubber waterproof sheet used in this invention.
We also tested the joints of vulcanized rubber waterproof sheets obtained by laminating A4090 films using a heat press at 150°C, heating the film surfaces with hot air (180°C), and then bonding them together. Once done,
The results shown in the table below were obtained.

It was found that it has the effect of having an adhesive force exceeding . Furthermore, according to the lamination method of the present invention viewed from points other than this adhesive force test, each device for laminating is smaller than the conventional heat press and T-die extruder, which were difficult to carry to the construction site. Since the vulcanized rubber tarpaulin sheet can be easily laminated at the construction site, the heat fusion film can be easily laminated even if the vulcanized rubber tarpaulin sheet is cut into a unique shape. Moreover, it is important to note that lamination can be performed at a much lower cost than those conventional methods. Although this example shows a case where the heat-sealing film is laminated to the edge of the vulcanized rubber waterproof sheet, the present invention is not limited to this, and for example, it may be laminated over one entire surface of the vulcanized rubber waterproof sheet. can also be considered. As described above, according to the method of laminating a heat-sealable film to a waterproof sheet of the present invention, a heat-sealable film is laminated onto a vulcanized rubber waterproof sheet using a hot plate, a pressure roll capable of supplying a heat-sealing material, and hot air. Because it is a laminated film, the heat retention and heat softening properties of the vulcanized rubber waterproof sheet are significantly improved.
As a result, it has great industrial value because it has very good adhesive strength and can be laminated extremely easily at construction sites.
