For example, "Asphalt and a waterproofing base material obtained by impregnating asphalt into a composite formed by bonding a nonwoven fabric layer and a woven fabric layer formed by randomly arranging long fibers of polyester with a needle punch" No. 54-148088). Alternatively, rubberized asphalt is often used as an improvement of a base material for waterproofing asphalt. For example, "A nonwoven fabric made of polyester fiber is impregnated with rubberized asphalt having a softening point of 90 ° C or higher, the same rubberized asphalt layer is provided on both surfaces thereof, and further subjected to anti-adhesion treatment with building sand, and then the longitudinal direction of the sheet. A waterproofing sheet for a roof base which is provided with a strip-shaped butyl rubber-based adhesive layer having a desired width and length on an edge portion and further cured with a curing film having releasability (Japanese Patent Laid-Open No. 57-176266) And so on.

取る。Next, the production method of the present invention will be described. First, a rubber compound obtained by mixing a softening agent and an inorganic filler with butyl rubber or the like is kneaded using a kneader, a Banbury, a rubber kneading roll, or the like. The kneaded compound is extruded from a wide slit die into a sheet by an extruder and guided to a calender roll. On the other hand, a tension is applied to the base fabric made of the detection yarn to maintain the tension, and at the same time, the sheet is guided to a calender roll. Thereafter, the speed of the calender roll and the conveyor belt are adjusted differently, and the rubber and the base fabric are shrunk and wound.
ラミネーティングの条件は加熱温度70〜130℃，圧力
２〜10kg/cm2,成型速度１〜10m/minが好ましい。The laminating conditions are preferably a heating temperature of 70 to 130 ° C., a pressure of 2 to 10 kg / cm 2 , and a molding speed of 1 to 10 m / min.
＜発明の作用効果＞ 本発明は下記の作用効果を有する。<Operation and Effect of the Invention> The present invention has the following operation and effect.
（１） 布帛とゴム層とのみからなる積層シートである
にもかかわらず布帛とゴム層との間の剥離を生じない。
これは前述したゴム系配合物を用いたことおよび基布と
して捲縮形態を有する繊維からなる高伸度性基布を用い
たことによる。(1) Despite being a laminated sheet composed of only a fabric and a rubber layer, no separation occurs between the fabric and the rubber layer.
This is due to the use of the rubber-based compound described above and the use of a high-extensibility base fabric made of crimped fibers as the base fabric.
（２） 本発明の防水シートは自己融着されてなるシー
トである。接着剤層を必要としない。(2) The waterproof sheet of the present invention is a sheet which is self-fused. No adhesive layer is required.
（３） 合成繊維あるいはガラス繊維からなる布帛を用

変形を生じた。そのため従来品では多少の縮み代を見込
んで被着体（床面など）に全面接着するかまたは浮かし
貼り加工で施工していた。しかしそれでも被着体面積よ
りなお縮むことが多く、そのときシート自体は伸長状態
となり光・熱による劣化を受け易く耐久性が低下する。
これに対し本発明品は縮み代を見込む必要がない。被着
体に接着施工した後シート自体が伸長状態になっても基
布収縮がこれを吸収する。(3) A conventional waterproof sheet using a cloth made of synthetic fibers or glass fibers has an elongation of 0 to 20%, and it is difficult to maintain the shape as it is, and deformation occurs due to return after construction. For this reason, in the conventional product, the whole is adhered to the adherend (floor surface or the like) or floated to allow for some shrinkage allowance. However, in many cases, the sheet still shrinks more than the area of the adherend, and at that time, the sheet itself is in an elongated state, and is susceptible to deterioration by light and heat, and the durability is reduced.
On the other hand, the product of the present invention does not need to allow for shrinkage allowance. Even after the sheet itself is stretched after being adhered to the adherend, the contraction of the base fabric absorbs this.
本発明の防水シートはたとえば伸長率40％でそのまま
の形態を安定に維持することができる。ビル屋上などの
屈曲した場所においても隙間なく屈曲部に適合するので
施工が容易であり、かつ施工後に屈曲部から離反するこ
とがない。The waterproof sheet of the present invention can stably maintain its shape at an elongation of 40%, for example. Even in a bent place such as a building roof, the fitting is easy without any gaps, so that the construction is easy and the construction does not separate from the bent part.
従来の比加硫系ゴムシートの場合は時間の経過に伴い
収縮変化を起すので形態寸法安定性を維持できなかった
が、本発明の防水シートは、捲縮により収縮力が吸収さ
れるのでかかる収縮変形を生じることがない。In the case of the conventional non-vulcanized rubber sheet, shrinkage change occurs with the lapse of time, so that the dimensional stability cannot be maintained. However, the waterproof sheet of the present invention is applied because the shrinkage force is absorbed by crimping. No shrinkage deformation occurs.
（４） ゴム系成分としてブチルゴム,EPDM,チオコール
ゴム，シリコンゴムなどを主体として用いているので、
防水シートの耐水性，耐候性，耐薬品性などが高い。(4) Since butyl rubber, EPDM, thiocol rubber, silicon rubber, etc. are mainly used as rubber components,
The waterproof sheet has high water resistance, weather resistance and chemical resistance.
（５） 本発明の防水シートは基布とゴム層とからなる
防水シートであってJIS−Ａ−6009の品質を充分にクリ
アすることができる。(5) The waterproofing sheet of the present invention is a waterproofing sheet comprising a base fabric and a rubber layer, and can sufficiently clear the quality of JIS-A-6009.
（６） 本発明の防水シートは−30〜100℃という広範
囲の温度範囲で使用することができる。従来のアスゴム
シート（アスベスト・ゴム複合シート）の使用可能温度
範囲は−10〜60℃である。(6) The waterproof sheet of the present invention can be used in a wide temperature range of −30 to 100 ° C. Usable temperature range of conventional as-rubber sheet (asbestos-rubber composite sheet) is -10 to 60 ° C.
