あった。[Problems to be solved by the invention] However, the waterproof sheet causes external damage to the surface due to falling accidents of heavy objects, sharp tools, pipes, etc. during or after construction, and as a result, leakage of rain occurs during rainfall. There has been a concern that this may occur and waste liquid may leak into the soil.

供することにある。The present invention was made in view of such a point, and the purpose thereof is to solve the above-mentioned drawbacks of the prior art,
It is an object of the present invention to provide a trauma self-repairing waterproof sheet capable of self-repairing naturally even if trauma occurs after the waterproof sheet is applied.

水シートにある。[Means for Solving the Problems] The gist of the present invention is that the self-weight is 50 to 1000.
A trauma self-repairing waterproof sheet, characterized in that two non-breathable polymer roofing sheets made of a synthetic rubber sheet are laminated and integrated on both sides of a water-swelling resin sheet having a water absorption capacity of about twice.

ムシートが用いられる。In the present invention, a synthetic rubber sheet is used as the non-breathable polymer roofing. As a synthetic rubber sheet,
The main component is one or more blended rubbers such as chloroprene rubber, ethylene propylene rubber, nitrile rubber, and styrene butadiene rubber, and inorganic fillers, oils, vulcanizing agents, antioxidants, etc. are kneaded to form a sheet. A molded and vulcanized rubber sheet is used.

A material having a water absorption capacity of about 0 times is preferable. When it is 50 times or less, the water absorption is insufficient, so that the object of the present invention for immediately preventing water leakage cannot be achieved, and when it is 1000 times or more,
Since the strength of the polymer itself after absorbing water is large, it cannot be used for a long time.

Two non-breathable polymer roofings made of synthetic rubber sheets are laminated and integrated on both sides of a water-swellable resin sheet having a water absorption capacity of about 1000 times, so that some kind of trauma after construction on a trauma self-repairing waterproof sheet. Even if occurs, the water-swelling resin sheet of the intermediate layer effectively absorbs water and swells, and the swelling causes the water-swelling resin sheet layer itself to block the external damage and to be laminated and integrated with the water-swelling resin sheet layer. The swelling material of the water-swelling resin sheet also extends into the wound portion of the two non-air-permeable polymer roofing layers, and it is possible to completely prevent further water entry from the outside.
しかも本考案の外傷自己補修防水シートは、自己補修で

凸もなく外観が良好である。Moreover, the self-repairing trauma sheet of the present invention is highly reliable because it can be self-repaired, and has a good appearance without the unevenness of the repaired portion as in the conventional case.

The water swells the resin sheet layer 2, and as a result, the swollen material of the resin sheet layer 2 extends not only to the damaged portion of the resin sheet layer 2 but also to the damaged portion of the non-breathable polymer roofing 1 to cause the damage. I will block it.
