などとして幅広く用いられており、なかでもエチレン・
プロピレンターポリマー（ＥＰＴ）を主成分とする加硫
ゴムシートが耐久性、強度などに優れているため特に多
用されている。Tarpaulin sheets are widely used as rooftop roofing materials or waterproof materials for civil engineering, among others, ethylene and
Vulcanized rubber sheets containing propylene terpolymer (EPT) as a main component are particularly widely used because of their excellent durability and strength.

と防水シート側の両面に接着剤を塗布する必要があるた
め作業性が悪いという問題がある。Conventionally, chlorobrene-based solvent-based adhesives have been used as adhesives for such waterproof sheets. However, this adhesive has a drawback in that it has low alkali resistance and easily peels off when rainwater enters through nail holes or poor adhesion at sheet joints. Furthermore, the bonding method using this adhesive has the problem of poor workability because it requires the use of a brimer and the need to apply the adhesive to both the base and the waterproof sheet side.

することがむすかしく、取り扱いにくい等、作業性が悪
いという欠点がある。In addition, adhesives using butyl rubber or halogenated butyl rubber can sufficiently adhere (adhesive) vulcanized rubber sheets containing EPT as a main component as is, but because butyl rubber or halogenated butyl rubber does not have crosslinking points. , it has the disadvantage of not exhibiting heat-resistant strength. In order to improve this drawback, various methods have been taken in recent years. For example, there is a method of crosslinking the rubber sheet itself, as seen in Japanese Patent Application Laid-Open No. 51-28656. It has the disadvantage of poor workability, such as being difficult to handle and difficult to handle.

のである。Therefore, in the present invention, 1 to 200 parts by weight of an organic compound having a molecular weight of 300 to 4000 and having at least two or more alkoxysilyl groups or isocyanate groups at the end is blended to 100 parts by weight of butyl rubber or halogenated butyl rubber. The gist is an adhesive composition characterized by:
以下、本発明の構成につき詳しく説明する。Hereinafter, the configuration of the present invention will be explained in detail.

安定性を得ようとするものである。(1) Among the butyl rubber and halogenated butyl rubber used in the present invention, examples of the halogenated butyl rubber include chlorinated butyl rubber and brominated butyl rubber. These butyl rubbers or halogenated butyl rubbers are
Although it is possible to sufficiently adhere (stick) a vulcanized waterproof rubber sheet made of EPT as the main component by oneself, the adhesive itself is not cross-linked, so the rubber sheet may move when used for a long period of time.
In the present invention, there is a problem of poor heat resistance strength.
In order to solve these problems, butyl rubber or halogenated butyl rubber is converted into IPN (I) with another compound.
PN: interpenetrating pol
ymer networks (interpenetrating polymer networks), it is intended to provide sufficient adhesive strength and long-term stability by providing a portion within the adhesive that functions as a crosslinking point.

The compound having at least two or more alkoxysilyl groups or isocyanate groups at the terminal is selected from polyethylene, isoprene, polyisobutyne, polybutadiene, and monomer units constituting these, taking into consideration compatibility with butyl rubber or halogenated butyl rubber. These are compounds that have a backbone skeleton with an SP value of around 8, such as compounds obtained by copolymerizing monomers. Particularly effective are compounds having alkoxysilyl groups at both ends of polyethylene, compounds having alkoxysilyl groups at both ends of ethylene-propylene copolymer, and compounds having isocyanate groups at both ends of hydrogenated polybutadiene. It is also possible to synthesize two or more types of silane coupling agents such as aminosilane and epoxysilane. Also, the molecular weight of this organic compound is
If the molecular weight is less than 300, which is from 300 to 4000, the adhesive will harden too much when used as an adhesion subcomponent, resulting in increased hardness and reduced peel strength in normal conditions. On the other hand, if the molecular weight exceeds 4,000, the entire adhesive will soften when heated, and the heat-resistant peel strength will not increase. This organic compound has at least two or more alkoxysilyl groups or isocyanate groups at the separated end, so when applying the adhesive, it may be exposed to moisture in the air or on the rubber sheet surface (or inside), moisture on the concrete surface or slate surface, and hydroxyl groups. It is considered to be compatible.

配合量が１重量部未満では反応が充分でないために熱時

接着力が劣化して常態での剥離強度があがらないからで
ある。If the amount is less than 1 part by weight, the reaction will not be sufficient and the peel strength will decrease when heated, and if it exceeds 200 parts by weight, the adhesive strength will deteriorate and the peel strength under normal conditions will not increase.

週間放置後、接着力測定試験を行なった。Adhesion conditions: In this example, a vulcanized rubber sheet for roofing (varnish sheet, manufactured by Shibata Kogyo) was used as the waterproof sheet, and the waterproof sheet and slate board (JIS A 5043 (JIS A 5043)
An adhesion test was conducted between F)). The vulcanized rubber sheet surface was used without being particularly treated with a solvent or the like. The adhesive was applied to the slate board with a spatula in an amount of 350g/rd, and after about 20 minutes of oven time, a rubber sheet was pasted together and pressed with a hand roller, and then left at room temperature for 1 hour.
After leaving it for a week, an adhesive force measurement test was conducted.

〔発明の効果〕
以上説明したように本発明の接着剤組成物は、従来品の
ようにブライマーを用いないので接着工法が繁雑でなく
、簡単な下地側−面塗布だけで充分な接着力が得られ、
かつアルカリ中においても高い接着力を保つので、モル
タル面、コンクリート面等におけるアルカリ耐性に優れ
る。(Margins below this page) [Effects of the Invention] As explained above, the adhesive composition of the present invention does not use a brimer unlike conventional products, so the adhesion method is not complicated and only requires simple side-to-side application of the base. Sufficient adhesive strength can be obtained with
Since it maintains high adhesive strength even in alkali, it has excellent alkali resistance on mortar surfaces, concrete surfaces, etc.
また、屋上などは真夏においては５０〜６０℃の温度ま
で上がるが、そのような温度でもある程度の耐熱接着力
を兼ねそなえているので、屋上ルーフィング材、あるい
は池、プール等の土木用防水材として有効に使用できる
という利点がある。In addition, rooftops can reach temperatures of 50 to 60 degrees Celsius in midsummer, and since they have a certain degree of heat-resistant adhesive strength even at such temperatures, they can be used as rooftop roofing materials or as waterproof materials for civil engineering works such as ponds and swimming pools. It has the advantage of being able to be used effectively.
