止効果を高めて使用している。Therefore, conventionally, the floor around the welding site, the machine, etc. are covered with a glass fiber cloth having excellent heat insulation and heat resistance to prevent the burnout and the like due to the sparks. In addition, since the glass fiber cloth alone has a limit in the above-mentioned prevention effect, water is included in the glass fiber cloth by sprinkling water such as rain and dew, and the cooling effect by water further enhances the burnout prevention and adhesion prevention effects. There is.
（発明が解決しようとする問題点） 上記従来技術においては、ガラス繊維クロスに浸透した
水がガラス繊維クロスのかぶせられた床や機械等に移動
してこれらを濡らしてしまうという問題点があった。(Problems to be Solved by the Invention) In the above-mentioned conventional technique, there is a problem that water that permeates the glass fiber cloth moves to a floor, a machine, or the like covered with the glass fiber cloth and wets them.
また、ガラス繊維クロスから水が容易に蒸発してしまう
ので、長時間作業のときは再々水をまく必要があった。
ガラス繊維クロスに水をまく場合、水の少ないところで
はガラス繊維が溶融し穴があく恐れがあり、多いところ
では床が激しく濡れる。さらに水をかけるときには溶接
溶断現場までその水を運搬しなければならない等の問題
点があった。Further, since water easily evaporates from the glass fiber cloth, it was necessary to re-sprinkle water when working for a long time.
When watering the glass fiber cloth, the glass fiber may melt and puncture in a place where there is little water, and the floor will be heavily wetted in a place where there is much water. Further, there was a problem that the water had to be transported to the welding fusing site when sprinkling water.

Since, for example, a large amount of water of 1 to 1.5 kg is impregnated in the water-swellable polymer, and the water-swellable polymer is mixed in the entire glass fiber cloth, the entire glass fiber cloth is impregnated with water, retained, and further impregnated. Easily evaporated water,
Do not move.
（実施例） 以下に本発明を具体化した一実施例を第１図及び第２図
を用いて説明する。(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
本発明の溶接断火花防止シート１は、第１図に示すよう

火花防止効果が薄く、一方5gを越えると得られるシート
が水を含浸したとき重くなりすぎて作業性が悪くなりや
すい。The manufacturing method is a method in which a powder of Aqua Keep 10SH is sprayed on the glass fiber cloth 2 and entangled in a spinning process for manufacturing the glass fiber cloth 2. The amount of Aquakeep 10SH used is preferably in the range of 0.5 to 5 g, and most preferably in the range of 1 to 2 g per 1 m 2 of glass fiber cloth. If the amount of Aqua Keep 10SH used is less than 0.5 g, the effect of preventing welding sparks from the resulting sheet is weak, while if it exceeds 5 g, the resulting sheet becomes too heavy when impregnated with water and the workability tends to deteriorate.

止シート1aとなる。When 1kg / m 2 of welding spark prevention sheet mixed with Aqua Keep 10SH is soaked in water, about 1.5kg of water absorbed by Aqua Keep 10SH and about water adhering to glass fiber cloth 2
When combined with 1.5 kg, about 3 kg of water is absorbed, resulting in a weight of 4 kg / m 2 . When lightly squeezed after that, only about 1.5 kg of water absorbed by Aqua Keep 10SH remains and the total weight becomes about 2.5 kg / m 2 , and as shown in Fig. 2, the thickness becomes thicker than before water absorption and water is absorbed. Is a welding spark prevention sheet 1a in which is evenly distributed.

行うことによって、床を溶接の火花から守ることができ
る。At a welding work site indoors, a floor or a machine around the work site is covered with the above-mentioned welding spark prevention sheet 1 of a predetermined size in which water is absorbed in advance. Then, the welding cutting work is started. The objects of welding cutting work include large objects such as machines, ships, buildings, gas tanks, reactors, etc. to small objects such as gas pipes, water pipes, drum pipes, window frames, etc. , Gas welding, resistance welding, etc. Even if sparks are scattered around during the welding cutting work, the sparks hit the welding spark prevention sheet 1 and do not scatter to the outside. Further, even when the floor is made of wood or resin, the floor can be protected from the sparks of welding by performing the welding operation after laying the welding spark prevention sheet 1 on the floor.
このように、溶接断火花防止シート１は可燃性材料に対

う必要もない。The above-mentioned welding spark preventive sheet 1 which has sufficiently absorbed water does not wet the water by moving to a floor covered with the glass fiber cloth, a machine or the like. In addition, since there is no unevenness of water sprinkling, there is no possibility of burnout where there is a small amount of water, or where the floor gets wet in a large amount of water. Furthermore, since the water swelling polymer 3 has a characteristic that the rate of evaporation of water impregnated therein is slow, it is not necessary to sprinkle water again during long-time work.
また、屋外で溶接断作業を行うときも、上記屋内におけ

である。Further, when performing the welding cutting work outdoors, the welding cutting work can be performed in the same manner as the indoor welding cutting work. Especially, when performing the welding cutting work outdoors in the summer, the evaporation rate of water is slow as described above. The main welding spark prevention sheet 1 that does not require watering is suitable.
本発明は上記実施例以外に次のように構成することもで
きる。The present invention can be configured as follows in addition to the above embodiment.

作業性が向上する。That is, in the above embodiment, only the water was impregnated in the welding spark prevention sheet 1, but an antifreeze solution such as ethylene glycol may be added to this. By adding antifreeze, you can prevent freezing of water in winter,
Workability is improved.

という優れた効果を奏する。EFFECTS OF THE INVENTION The welding spark prevention sheet of the present invention has no downward movement of water that has penetrated into the glass fiber cloth, and does not need to be watered again by evaporation of water. In addition, when water is sprinkled on the glass fiber cloth, not only can water sprinkling be uneven, but the water will not drip from the glass fiber cloth and the floor will not get dirty, and it will not be necessary to transport the water to the welding site. Produce an effect.
