Abstract
Description
本発明は、熱膨張性パテ組成物、及び目地材に関する。 TECHNICAL FIELD The present invention relates to a thermally expandable putty composition and a joint filler.
一般に、建築物等において建築基準法で定められた防火区画等に配管類や電力ケーブルや通信ケーブル等のケーブル類を貫通させる場合、延焼防止等の観点から防火区画等には一定の耐火性能が求められている。そのため、建築物内の配管類・ケーブル類と防火壁等との間には、防火性能を付与した防火用目地材として、樹脂に金属水和物等を配合したパテ状の耐火材が用いられている。 In general, when pipes, power cables, communication cables, etc. are passed through a fireproof section of a building, etc., the fireproof section must have a certain level of fireproof performance from the viewpoint of preventing the spread of fire. It has been demanded. For this reason, a putty-like fireproof material made by mixing metal hydrate with resin is used as a fireproof joint material with fireproof performance between pipes/cables and fireproof walls in buildings. ing.
例えば、特許文献１には、形状安定性に優れたノンハロゲン系の防火パテ組成物が記載されている。また、火災時に配管類が変形したり、ケーブル被覆材が燃焼したりすることで生じた隙間を塞ぐことが出来るパテ状耐火材として、バーミキュライトや、熱膨張性黒鉛や、マイクロカプセル化したポリリン酸アンモニウムを有機樹脂に混合した樹脂組成物（例えば、特許文献２参照）や、ベース樹脂に熱膨張性黒鉛と共にポリカーボネート樹脂やポリフェニレンサルファイド樹脂等の形崩れ防止用樹脂を配合した熱膨張性の組成物（例えば、特許文献３参照）も提案されている。 For example, Patent Literature 1 describes a non-halogen fireproof putty composition having excellent shape stability. In addition, vermiculite, thermally expandable graphite, and microencapsulated polyphosphoric acid are used as putty-like refractory materials that can close gaps caused by deformation of pipes or burning of cable covering materials in the event of a fire. A resin composition in which ammonium is mixed with an organic resin (see, for example, Patent Document 2), or a thermally expandable composition in which a resin for preventing deformation such as a polycarbonate resin or a polyphenylene sulfide resin is added to a base resin together with thermally expandable graphite. (see, for example, Patent Document 3) has also been proposed.
このような耐火材には、熱膨張性に加えて、熱膨張後に型崩れや崩壊しないように熱膨張後の形状安定性も求められる。また、施工後に型崩れや崩壊しないようにパテ状の耐火材が乾燥後の形状安定性も求められる。 Such a refractory material is required to have shape stability after thermal expansion in addition to thermal expansibility so as not to lose its shape or collapse after thermal expansion. In addition, the putty-like refractory material is also required to have shape stability after drying so that it does not lose its shape or collapse after construction.
本発明はこのような事情に鑑みてなされたものであり、十分な熱膨張性を有しつつ、優れた乾燥時の形状安定性及び熱膨張後の形状安定性を有する熱膨張性パテ組成物を提供するものである。 The present invention has been made in view of such circumstances, and provides a thermally expandable putty composition having sufficient thermal expansibility and excellent shape stability during drying and shape stability after thermal expansion. It provides

１．熱膨張性パテ組成物
本実施形態の熱膨張性パテ組成物は、無機系粘土鉱物、熱膨張性黒鉛、上記無機系粘土鉱物及び上記熱膨張性黒鉛以外のその他の無機化合物（以下、単に「その他の無機化合物」ともいう。）、を含み、上記無機系粘土鉱物、上記熱膨張性黒鉛、及び前記その他の無機化合物の総量１００重量部に対して、上記無機系粘土鉱物の含有量が、４．０～３０重量部であり、上記熱膨張性黒鉛の含有量が、１．０～５０重量部であり、上記その他の無機化合物の含有量が、２１～９４重量部である、熱膨張性パテ組成物である。また、熱膨張性パテ組成物は、必要に応じてその他の成分を含んでいてもよい。
1. Thermally expandable putty composition The thermally expandable putty composition of the present embodiment includes an inorganic clay mineral, thermally expandable graphite, and other inorganic compounds other than the inorganic clay mineral and the thermally expandable graphite (hereinafter simply “ Also referred to as "other inorganic compounds"), and the content of the inorganic clay mineral is 4.0 to 30 parts by weight, the content of the thermally expandable graphite is 1.0 to 50 parts by weight, and the content of the other inorganic compound is 21 to 94 parts by weight. It is an elastic putty composition. Moreover, the thermally expandable putty composition may contain other components as necessary.
１．１．無機系粘土鉱物
無機系粘土鉱物は、主に粘結材として機能することができ、無機系粘土鉱物を適量配合することによって、熱膨張性パテ組成物を施工に適した硬さにすることができ、乾燥後の形状安定性のほか、熱膨張後の形状安定性を向上することもできる。このような無機系粘土鉱物としては、天然由来であっても化学合成由来のものであってもよく、特に限定されないが、例えば、層状珪酸塩鉱物、繊維状珪酸塩鉱物等が挙げられる。無機系粘土鉱物は１種単独で用いてもよいし、２種以上を併用してもよい。
1.1. Inorganic Clay Minerals Inorganic clay minerals can mainly function as a caking agent, and by blending an appropriate amount of inorganic clay minerals, the thermally expandable putty composition can be made to have a hardness suitable for construction. In addition to the shape stability after drying, the shape stability after thermal expansion can also be improved. Such inorganic clay minerals may be naturally derived or chemically synthesized, and are not particularly limited. Examples thereof include lamellar silicate minerals and fibrous silicate minerals. An inorganic clay mineral may be used individually by 1 type, and may use 2 or more types together.
後述するなかでも、無機系粘土鉱物は、その中でも層状珪酸塩鉱物又は繊維状珪酸塩鉱物のうち少なくともいずれかを含むことが好ましく、ベントナイト、モンモリロナイト、スメクタイト、ヘクトライト、及びセピオライトからなる群より選ばれる少なくとも一種を含むことがより好ましい。本実施形態の熱膨張性パテ組成物が、このような無機系粘土鉱物を所定量含むことにより、熱膨張性や熱膨張後の形状安定性が優れる傾向にある。 Among them, among others, the inorganic clay mineral preferably contains at least one of layered silicate minerals and fibrous silicate minerals, and is selected from the group consisting of bentonite, montmorillonite, smectite, hectorite, and sepiolite. It is more preferable to include at least one kind of When the thermally expandable putty composition of the present embodiment contains a predetermined amount of such an inorganic clay mineral, it tends to be excellent in thermal expansibility and shape stability after thermal expansion.
無機系粘土鉱物を水に分散させた４．０質量％分散液の粘度は、１０～１２０００ｍＰａ・ｓであることが好ましく、１０～６０００ｍＰａ・ｓであることがより好ましい。４．０質量％分散液の粘度は無機系粘土鉱物の粘性を示すものであり、４．０質量％分散液の粘度が上記範囲内であることにより、乾燥時の形状安定性及び熱膨張後の形状安定性がより向上する傾向にある。また、建築物内の配管類・ケーブル類と防火壁等との間の隙間をふさぐ際にその作業性がより向上する傾向にある。 The viscosity of a 4.0% by mass dispersion of an inorganic clay mineral dispersed in water is preferably 10 to 12000 mPa·s, more preferably 10 to 6000 mPa·s. The viscosity of the 4.0% by mass dispersion indicates the viscosity of the inorganic clay mineral, and when the viscosity of the 4.0% by mass dispersion is within the above range, the shape stability during drying and after thermal expansion shape stability tends to be further improved. In addition, there is a tendency for workability to be further improved when closing gaps between pipes/cables and firewalls in a building.

Here, the higher the three-point bending breaking strength, the higher the strength after thermal expansion. Then, based on the three-point bending fracture strength, the shape stability after thermal expansion was determined according to the following evaluation criteria.
〔Evaluation criteria〕
A: The three-point bending breaking strength is 3.0 [N] or more.
○: The three-point bending breaking strength is 1.0 [N] or more and less than 3.0 [N].
x: Three-point bending breaking strength is less than 1.0 [N].
＜非付着性＞

付着物重量［ｇ］＝（パテを１０回握った後の手袋の重量）－（元の手袋の重量）
〔評価基準〕
◎：付着物重量が０．３［ｇ］未満である。
○：付着物重量が０．３［ｇ］以上、１．０［ｇ］未満である。

×：付着物重量が１．５［ｇ］以上である。
<Non-adherence>
A latex rubber glove was put on, and the weight of the deposit on the glove was measured after gripping the putty 10 times, and the weight of the deposit was calculated based on the following formula. Then, based on the weight of the deposit, the non-adherence was determined according to the following evaluation criteria.
Deposit weight [g] = (glove weight after gripping putty 10 times) - (original glove weight)
〔Evaluation criteria〕
⊚: Deposit weight is less than 0.3 [g].
Good: The weight of deposit is 0.3 [g] or more and less than 1.0 [g].
Δ: Deposit weight is 1.0 [g] or more and less than 1.5 [g].
x: Deposit weight is 1.5 [g] or more.

〔評価基準〕
◎：貫入深さが１２０［１／１０ｍｍ］以上２００未満［１／１０ｍｍ］である。
○：貫入深さが７０［１／１０ｍｍ］以上１２０［１／１０ｍｍ］未満、又は、２００［１／１０ｍｍ］以上２３０［１／１０ｍｍ］未満である。

×：貫入深さが５０［１／１０ｍｍ］未満、又は２５０［１／１０ｍｍ］以上である。
<Workability>
The hardness of the thermally expandable putty composition before drying was measured according to JIS A5752 at a load of 150 g and a temperature of 21°C. Next, a specified cone was vertically penetrated into the specimen and the penetration depth was measured in units of 0.1 mm. Finally, based on the penetration depth, workability was determined by the following evaluation criteria.
〔Evaluation criteria〕
A: The penetration depth is 120 [1/10 mm] or more and less than 200 [1/10 mm].
○: The penetration depth is 70 [1/10 mm] or more and less than 120 [1/10 mm], or 200 [1/10 mm] or more and less than 230 [1/10 mm].
Δ: The penetration depth is 50 [1/10 mm] or more and less than 70 [1/10 mm], or 230 [1/10 mm] or more and less than 250 [1/10 mm].
x: Penetration depth is less than 50 [1/10 mm] or 250 [1/10 mm] or more.
