として比重の大きい鉛粉、鉛化合物、鉄粉、酸化鉄スラ
グ、パライト（硫酸バリウム）などが使用されている。In order to obtain a sound insulating material that has a high sound insulating effect against these noises, the mass of the sound insulating material (T L = a log mf + b, TL is the transmission loss (dB), m is areal density (kg/m''), f is frequency (Hz), and a and b are constants], it is necessary to mix a filler with a large specific gravity into a binder material with good workability. In the past, attempts were made to achieve sound insulation by mixing large amounts of inorganic fillers such as calcium carbonate and aluminum hydroxide into organic binder materials, but these fillers did not have a high specific gravity as a sound insulation material. , the sound insulation effect was insufficient.Currently known sound insulation materials are:
Natural rubber, synthetic rubber, rubber adhesives, polyethylene, polypropylene, polyvinyl chloride, synthetic resin adhesives, asphalt, etc. are used as binder materials, and lead powder with high specific gravity, lead compounds, iron powder, and oxidation are used as fillers. Iron slag, pallite (barium sulfate), etc. are used.
しかし、鉛粉、鉛化合物は、比重が高（て好ましいが、
価格が高く、燃焼時に酸化鉛の有害粉じんガスを発生す

に欠ける問題がある。However, lead powder and lead compounds have a high specific gravity (which is preferable, but
Its use is problematic because it is expensive and produces harmful lead oxide dust gas when burned. Iron powder is also a preferred filler due to its high specific gravity, but it is expensive, rusts due to humidity, seriously impairs the appearance, and the sound insulation material swells.
There are problems such as deformation. Although iron oxide slag is inexpensive, its specific gravity is lower than the former because it contains a large amount of calcium oxide, and when iron oxide slag is kneaded into thermoplastic resin, it adheres to the roll surface significantly, making it difficult to process. There is a problem with this.
パライトはその組成が硫酸バリウムであり、比重も高い
が、輸入依存のため原材料入手に難がある。Palite has the composition of barium sulfate and has a high specific gravity, but it is difficult to obtain raw materials because it relies on imports.

消火活動や誘導避難に支障をきたすという問題がある。On the other hand, most of the binder materials used in flexible sound insulation materials for noise prevention use flammable materials, so once they come into contact with flame and burn, they generate a large amount of black smoke and harmful gases, which can be used to extinguish fires. There is a problem in that it interferes with activities and guided evacuation.

It has thermal stability; (i) it is flame retardant and does not emit harmful gases in the event of a fire; and (i) it is a sound insulating material with excellent flexibility and workability.

The present invention was completed by discovering that by blending one or both of the polymers with iron concentrate slag and antimony dioxide, which are by-products of the copper smelting process, excellent flame retardancy and sound insulation properties can be achieved. .

以下、本発明にがかる難燃性遮音材の組成物について、
更に詳細に説明する。Below, regarding the composition of the flame retardant sound insulation material according to the present invention,
This will be explained in more detail.

塩化ビニル共重合体などである。The vinyl chloride resin used in the present invention includes vinyl chloride resin, ethylene/vinyl chloride copolymer polymerized with vinyl chloride, vinyl acetate/vinyl chloride copolymer, or urethane/vinyl chloride copolymer.
These include vinyl chloride copolymers.

１００重量部である。The plasticizer used in the present invention is not particularly limited as long as it is a plasticizer that can be blended with vinyl chloride resin. The amount of plasticizer blended is based on 100 parts by weight of vinyl chloride resin.
The range is 30 to 150 parts by weight, preferably 50 to 150 parts by weight.
It is 100 parts by weight.

強度が低下するので好ましくない。The blending amount of one or both of the ethylene vinyl acetate copolymer or the ethylene vinyl acetate vinyl chloride terpolymer is as follows:
30 to 150 parts by weight of vinyl chloride resin
If the amount is less than 30 parts by weight, the resulting sound insulation material will have poor flexibility, and if it exceeds 150 parts by weight, the mechanical strength of the sound insulation material will decrease. So I don't like it.

30% by weight), Fe30410''30% by weight, Fe
35% by weight of 2O, 5% by weight of MgO or less, and CaO
Contains almost no The iron concentrate slag is a by-product obtained in the copper smelting process, so it is inexpensive and produced in large quantities. Moreover, it has undergone flotation and is conveniently crushed particles. The bulk density of the slag is 3 to 4, and the specific gravity is 5.
~5.5, so it is preferable as a filler for sound insulation materials. The particle size of the iron concentrate slag used in the present invention is 1
00 meshes or less is preferable, and particularly 200 meshes or less is more preferable.

。The amount of iron concentrate slag blended is in the range of 400 to 2000 parts by weight, preferably 600 to 1200 parts by weight, based on 100 parts by weight of the vinyl chloride resin. If the amount of iron concentrate slag is less than 400 parts by weight, the specific gravity of the sound insulating material will not increase, resulting in poor sound insulating properties and lack of flame retardancy.
逆に、２０００重量部を超えるときは、混練りの加工性
がわるく、得られる遮音材は柔軟性を欠き、機械的強度
が低下するので好ましくない。On the other hand, when it exceeds 2000 parts by weight, the kneading processability is poor, the resulting sound insulating material lacks flexibility, and its mechanical strength is reduced, which is not preferable.

量が５重量部未満では、得られる遮音材の難燃性が満足
されない。The blending amount of antimony trioxide is 100% of vinyl chloride resin.
It ranges from 5 to 30 parts by weight, preferably from 10 to 20 parts by weight. If the amount of antimony dioxide is less than 5 parts by weight, the resulting sound insulation material will not have satisfactory flame retardancy.
逆に、３０重量部を超えるときは、難燃性の向上がなり
、飽和するので価格的に不経済なものとなる。On the other hand, if it exceeds 30 parts by weight, the flame retardance will not be improved and will become saturated, making it uneconomical in terms of price.

特性が良好なものとなる。○ mark: Fire does not spread × mark: Fire spread As can be seen from the results, in Examples 1 to 6, the specific compound materials used in the present invention were appropriately combined, so the specific gravity of the sound insulating material was 2. If it is in the range of .37 to 3.01, it exhibits sound insulation properties and has good properties such as flexibility, processability, flame retardance, and low smoke emission.

加工性に欠く。Next, looking at comparative examples, in comparative example 1, since the amount of iron concentrate slag is small, the specific gravity is low and the sound insulation properties are not desirable. Comparative Example 2 lacks flexibility and workability due to the large amount of iron concentrate slag.

でないため、加工性に欠く。Comparative Examples 3 and 4 lacked flexibility and processability because the amounts of one or both of the ethylene vinyl acetate copolymer and the ethylene vinyl acetate vinyl chloride terpolymer were small. Comparative example 5 is
Since antimony trioxide powder is not added, flame retardancy cannot be expected at all. Comparative Examples 6 and 7 lacked workability because the amount of plasticizer was not appropriate.
