The present invention relates to a waterproof sheet for reinforcing corners, and more particularly, to a waterproof sheet that can be used to reinforce corners in complex areas such as outside corners, inside corners, and around pipes in a short time. Here, reinforcement pasting is a construction method adopted in complex areas, and before pasting the wide waterproof sheet,
This is a method of pasting a waterproof sheet over a small area to ensure waterproofing in complex areas. Conventionally, reinforcement pasting of complicated areas, such as protruding corners, is usually done by combining a waterproof sheet 1 cut into an approximately square shape and a waterproof sheet 2 whose lower half is cut into an approximately square shape, as shown in Fig. 1. First, after applying adhesive 4 to the back surfaces of waterproof sheets 1 and 2 and the base 3,
After pasting the waterproof sheet 1 on the base and rolling it, adhesive was applied to the parts of the waterproof sheet 1 where it overlapped with the other waterproof sheet 2, and after an open time, the other waterproof sheet 2 was pasted. However, since adhesive is required when using this type of waterproof sheet, there are constraints such as a prescribed amount of application, open time, and appropriate pressure bonding, and these conditions are greatly influenced by the environmental conditions at the time of work. ing. For example, in strong winds, adhesion is inhibited by adhesion of dust, in high temperatures the open time becomes short and over-drying causes adhesion failure, and in low temperatures the open time increases, affecting construction efficiency and further. At high temperatures, condensation water may adhere to the adhesive surface, resulting in poor adhesion, so it was necessary to fully understand the environmental conditions. In addition, there are many other causes of poor adhesion, such as variations in adhesive strength due to uneven coating and poor adhesion due to insufficient rolling pressure. Therefore, reinforcing the corners of complex areas using adhesives is greatly influenced by the environment at the time.
Furthermore, the construction required a considerable amount of time. Moreover, when applying reinforcement using a vulcanized rubber sheet, it is difficult for the vulcanized rubber sheet to adhere to the underlying surface at the corners, and water vapor in the substrate such as concrete may expand during the day, causing the sheet to swell. Also, once air is trapped between the waterproof sheet and the underlying surface during the process of laying the waterproof sheet, it becomes difficult to remove the air during the subsequent compaction process, and this causes the waterproof sheet to not fit properly. There were cases where a bad water path was created and water leaked. In view of the above-mentioned actual situation, this invention aims to improve these points by providing a system that is not affected by the work environment.
It is an object of the present invention to provide a waterproof sheet that can be easily and reliably reinforced at corners of complicated locations in a short time. That is, the feature of the present invention is that it is a waterproof sheet used for reinforcing and pasting corners of complicated places such as outside corners, inside corners, or around pipes, and is made of ethylene-propylene-terpolymer, butyl rubber, or these materials. The base material of the vulcanized rubber sheet made of a blend contains ethylene-propylene terpolymer, butyl rubber, or a rubbery polymer made of a blend thereof, a vulcanizing agent, a vulcanization accelerator, etc., and has a Mooney viscosity (ML 1 + 5) . , 100°C) 5 to 20°C) and has a structure in which self-curable adhesive layers that are self-adhesive and can be self-vulcanized are laminated and bonded. Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. FIG. 2 shows a sectional view of the waterproof sheet of the present invention, and the waterproof sheet 5 is composed of a base material 6 of a vulcanized rubber sheet and an adhesive layer 7 that can be naturally vulcanized. The base material 6 is a vulcanized rubber sheet made of ethylene-propylene terpolymer, butyl rubber, or a blend thereof, which has excellent weather resistance, and the adhesive layer 7 is made of ethylene-propylene terpolymer, butyl rubber, or a blend thereof. In addition to a vulcanizing agent, a vulcanization accelerator, an adhesive, and a softening agent, stearic acid, carbon black, inorganic fillers, ZnO, etc. are appropriately mixed and blended into the rubbery polymer consisting of a blend. Layered. The vulcanizing agents used here include sulfur,

These vulcanizing agents can be used in an amount of 1 part by weight per 100 parts by weight of the rubbery polymer.
It is used in a proportion of about 6 parts by weight. Further, as the vulcanization accelerator, 2-mercaptobenzothiazole, di. Benzothiazole. Thiazoles such as disulfide, tetramethylthiuram. Monosulfide, tetramethylthiuram.
Disulfide, dipentamethylenethiuram. Examples include thiuram-based materials such as hexulfide, dithiocarbamate-based materials such as Zn-di-n-butyldithiocarbamate, and PbO 2 and trimene-based materials. The amount of these vulcanization accelerators used is
The amount is usually 2 to 10 parts by weight per 100 parts by weight of the rubbery polymer. Adhesives to be further mixed include aromatic hydrocarbon resins such as petroleum-based hydrocarbon resin Petrozin (manufactured by Mitsui Petrochemicals), aliphatic cyclic hydrocarbons such as Hiretz (manufactured by Mitsui Petrochemicals), These adhesives include unsaturated hydrocarbon polymers such as Escorets (manufactured by Etsutsu Chemical Co., Ltd.), hydrocarbon adhesive resins such as Kutsuku Ace (manufactured by Mitsui Petrochemicals Co., Ltd.), and phenol resins such as phenol formaldehyde resin. Usually, the preferred amount used is about 30 to 100 parts by weight per 100 parts by weight of the rubbery polymer. In addition, known softeners are used with these adhesives, typical examples of which are process oil,
Examples include polybutene, liquid paraffin, pine tar, and other petroleum-based high-boiling compounds. The amount of these softeners used is
Preferably 30 parts by weight of rubbery polymer
~150 parts by weight. Next, the adhesive layer 7 used in the present invention has an initial adhesive strength with the base material of another waterproof sheet, that is,
The self-adhesive force after rolling the joint with a roller, etc. must be approximately 1.0 to 3.0 kg/25 cm.
Without this self-adhesive force, when the waterproof sheet is pulled when reinforcing the corners, the waterproof sheet will shift and deform at the joints. Therefore, in order to satisfy this self-adhesive strength, the adhesive strength must be adjusted using a rubbery polymer.
Add 30 to 100 parts by weight to 100 parts by weight to give the surface tack, and further add 30 to 150 parts by weight of a softener to increase the Mooney viscosity of the adhesive layer (ML 1 + 5 , 100℃)
It is important to keep the viscosity in the range of 5 to 20. With this Mooney viscosity, even if dirt or dust adheres to the surface of other adherends, the adhesive layer will surround these foreign substances and will not disturb them. Since foreign matter penetrates into the adhesive layer, the adhesion between the waterproof sheet and other adherends is not affected much. Here, the thickness of the adherend, for example, the adhesive tape, should be in the range of 0.5 to 2.0 mm; if it is more than 2.0 mm, a step will be created at the joint with the waterproof sheet, which is not preferable because it will be likely to peel off at the initial stage of joining. Among these, the thickness of the adhesive layer 7 is preferably 0.5 to 2.0 mm. Next, an example of using the waterproof sheet 5 according to the present invention for reinforcing the corners of complicated areas will be explained.
FIG. 3 is a perspective view showing reinforcing pasting at the protruding corners. First, a waterproof sheet 5 cut into a substantially square shape is laid down with the adhesive layer 7 facing the base 3, and then rolled and pressed. Subsequently, another waterproof sheet 5' with a cut in the center of the lower half is laid on each base 3, and after the above-mentioned waterproof sheet 5 and the wrap portion 8 are provided, the entire surface is rolled to complete the reinforcing pasting work. On the other hand, Fig. 4 is a perspective view showing the reinforcing of the inner corners, in which a substantially square waterproof sheet 5' with a cut in the center of the lower half is laid on each base surface, and a part of the base surface is After layering the waterproof sheet 5 in two layers, the entire surface of the sheet was rolled to complete the reinforcement application. Thus, reinforcing pasting work is carried out as described above, but in order to more specifically explain the suitability of work when performing reinforcing pasting using the waterproof sheet of the present invention, we will explain in more detail the suitability of work when performing reinforcing pasting using the waterproof sheet of the present invention. The waterproof sheet of the present invention (the composition of the base material 6 and the adhesive layer 7 was

Because the installation can be completed simply by rolling, it is possible to perform the reinforcing work in a shorter time than with conventional methods.In addition, due to the complexity of the shape, it is possible to apply reinforcement to the corners of complex areas. During the process of laying a tarpaulin sheet, air may be trapped between the sheet and the underlying surface, which in turn causes the sheet to not fit properly, creating a water channel and leading to water leakage, which requires considerable construction skill. In the case of the waterproof sheet of the present invention, which has a thick adhesive layer, the waterproof sheet blends well with the substrate due to the deformation of the adhesive layer during the rolling process, and can be applied while peeling off the release paper, so air is excluded and air is removed. It has the advantage that even unskilled workers can easily install it because it does not contain any substances.
Moreover, since the adhesive layer of the waterproof sheet of this invention has sufficient surface tack, it does not lift up from the base even after compaction, and it is naturally vulcanized by solar heat and environmental temperature, creating a strong bond with the adherend. It has the ability to provide long-term adhesive properties.
