られている。[Prior Art] As a sound insulation putty used for the above-mentioned applications, one is known in which a high specific gravity substance is blended with a binder resin to enhance the sound insulation effect (for example, JP-A-57-187379). As such a high specific gravity substance, high specific gravity inorganic particles are used.

火炎の伝播が著しい。[Problems to be Solved by the Invention] However, even if the sound insulation putty known so far has excellent sound insulation properties, it is not satisfactory in terms of fire resistance. That is, when exposed to flame, the binder resin melts and falls off, or cracks occur, making it impossible to prevent the flame from spreading from the sound-insulating putty. In particular, when the specific gravity of sound insulation putty is increased by mixing a large amount of high specific gravity inorganic particles, when exposed to flame, the molten binder resin cannot hold the high specific gravity inorganic particles and easily It fell off and the flame spread was significant.
本発明は、このような問題点を解決し、優れた耐火性を
有する遮音効果の高い遮音パテを提供するものである。The present invention solves these problems and provides a sound insulating putty with excellent fire resistance and a high sound insulating effect.

有機難燃繊維０．５〜４０重量部とを、配合してなるも
のである。[Means for Solving the Problems] The sound insulation putty of the present invention contains 200 to 1300 parts by weight of iron concentrate slag to 100 parts by weight of liquid chloroprene rubber,
It is made by blending 0.5 to 40 parts by weight of organic flame retardant fiber.

A sound-insulating putty is obtained.

いない。The iron concentrate slag used in the present invention is a by-product obtained in the copper smelting process, and silicon dioxide and oxygen are added to the matte obtained from the flash furnace in the copper smelting process in a converter to convert it into silicate. After oxidation, the resulting slag is subjected to magnetic separation, and the resulting slag is floated to recover copper concentrate, which is obtained by dehydrating the residue. An example of the chemical composition of this iron concentrate slag is 2FeO-8iO3 (Feo: 40~
50% by weight, 15-30% by weight as S I O2),
Fe204 10-30% by weight, Fe2O, 5% by weight, M

ための充填剤として好ましいものである。この発明で使
用する鉄精鉱スラグの粒度は、１００メツシユ以下が好
ましく、特に２００メツシユ以下がより好ましい。As described above, this iron concentrate slag is a by-product obtained in the copper smelting process, so it is inexpensive and produced in large quantities. Furthermore, it has undergone flotation and is conveniently crushed particles. In addition, the bulk density of this iron concentrate slag is 3 to 4.
Since it has a specific gravity of 4 to 4.2, it is preferable as a filler for enhancing the sound insulation effect. The particle size of the iron concentrate slag used in this invention is preferably 100 mesh or less, particularly preferably 200 mesh or less.
鉄精鉱スラグの配合量が液状クロロプレンゴム１００重

より多い時は、垂れ下がったり、粘着性が低下したり、

したりするので、いずれも好ましくない。より良いもの
を得るために、かかる鉄精鉱スラグは、７００〜１２０
０重量部配合すること配合ましい。When the amount of iron concentrate slag blended is less than 200 parts by weight per 100 parts by weight of liquid chloroprene rubber, the specific gravity will not be high and a sufficient sound insulation effect will not be obtained. Also, if it exceeds 1300 parts by weight, it may sag or the adhesiveness may decrease.
Both of these are undesirable, since the filling workability is lowered and the cross-wire workability is significantly lowered. In order to get better, such iron concentrate slag should be made from 700 to 120
It is preferable to add 0 parts by weight.
本発明において使用する有機難燃繊維とは、火炎に接し
た場合、該繊維が炭化するような、たとえばフェノール
ホルムアルデヒド樹脂系の繊維、カーボン系の繊維等が
これに該当する。The organic flame-retardant fibers used in the present invention include, for example, phenol-formaldehyde resin-based fibers, carbon-based fibers, etc., which are carbonized when exposed to flame.
その繊維長は１〜１０ＩＩＩＩＩのものを用いることが
好ましい。It is preferable to use a fiber having a fiber length of 1 to 10III.
有機難燃繊維を配合することにより、遮音パテの垂れ下
がりを防止するとともに、火災時におけるバインダー樹
脂の溶融脱落を有効に防止する。By blending organic flame-retardant fibers, the sound insulation putty is prevented from sagging, and the binder resin is effectively prevented from melting and falling off in the event of a fire.
有機難燃繊維の配合量が、液状クロロプレンゴム１００
重量部に対して、０．５重量部より少ない時は、高比重
となる本発明の遮音パテの垂れ下がりを防止する作用が
不十分となり、さらに、延焼防止効果面でも寄与しなく
なる。逆に４０重量部より多い場合には、混練加工性や
、充填作業性に劣ることになる。なお、繊維長にもよる
が、通常、１〜３０重量部配合配合ことが好ましい。The amount of organic flame retardant fiber is liquid chloroprene rubber 100%
When the amount is less than 0.5 part by weight, the effect of preventing the sound insulating putty of the present invention, which has a high specific gravity, from sagging will be insufficient, and furthermore, it will not contribute to the fire spread prevention effect. On the other hand, if the amount is more than 40 parts by weight, the kneading processability and filling workability will be poor. Although it depends on the fiber length, it is usually preferable to mix 1 to 30 parts by weight.

り長さ１５０ｍｍ、内幅１０ｍｍ。(4) Sagging property 711 was determined by a method based on JIS A 5752.5.5. That is, the pearlite board (insulating material) has a length of 150 mm and an inner width of 10 mm.

器の下端から垂れ下がった遮音パテの長さを測定した。A groove with a depth of 25m+s was filled with sound insulating putty, and when it was suspended in a constant temperature air tank at 20℃ for 24 hours, and then in a constant temperature air bath at 60℃ for 24 hours, the sound from the bottom of the container was The length of the hanging sound insulation putty was measured.

填作業性が悪かった。On the other hand, in the sound insulation putty of Comparative Example 1, since the phenol formaldehyde resin fiber was not blended, the flame retardance was inferior and the sagging property was large. Furthermore, in this comparative example, the proportion of liquid chloroprene rubber in the sound insulation putty was large, so the sound insulation putty became sticky and the filling workability was poor.

遮音パテがかたくなって充填作業性が悪かった。In the sound insulation putty of Comparative Example 2, since the amount of iron concentrate slag blended was too large, the sagging property increased, and
The sound insulation putty became hard and the filling workability was poor.
