言えない。Recently, a soundproofing material has been proposed in which a vinyl chloride resin containing a plasticizer is combined with iron oxide, which is a by-product of the steel manufacturing process (Japanese Patent Application Laid-open No. 57-34064). It is emphasized that the oxide has excellent adhesive properties with vinyl chloride. However, the above-mentioned soundproofing materials have poor release properties from the roll surface during molding and take a long time to gel.
The mechanical properties when formed into a sheet are also not satisfactory.

樹脂類との接着性が特に優れており、またｎＦｅ。The composition of the filler according to the present invention is particularly important, and it contains 50 to 90% by weight of iron oxide and 10 to 30% by weight of silica. On the other hand, it is necessary that the total content of alkali metal oxides or alkaline earth metal oxides is 10% by weight or less.

で留意すべきである。Further, it should be noted that if the content of iron oxide in the entire filler is less than 50%, sufficient sound insulation properties cannot be exhibited.
なお、酸化鉄の含有量の上限は次に述べるシリカの含有
必要量により決められる。Note that the upper limit of the content of iron oxide is determined by the required amount of silica to be included, which will be described below.

く、３０重量％が１製界である。Silica, which is another essential component of the filler of the present invention, has a bulk density of around 0.3 to 1, and has a bulk density of around 0.3 to 1.
Although it is small compared to ~6 and is not useful for improving the areal density when used in composite materials, the presence of this silica can significantly increase the amount of iron oxide filling and improve the surface smoothness of the product. Demonstrates the effect of improving. Thus, it is important to have at least 10 types of silica present in the filler to increase iron oxide loading in the composite. However, as mentioned above, silica itself has a low density, so it is not preferable to have a large amount of silica present in the filler because it will suppress the amount of high-density filling, and 30% by weight is 1 production limit.

ないほどが望しい。Furthermore, in the filler of the present invention, alkali metal oxides or alkaline earth metal oxides, such as Na, O, Mg
The lower the content of O, CaO, etc., the better, and it is necessary to limit the total content to 10% by weight or less, preferably 7% by weight or less, particularly 5% by weight or less. The presence of these oxides causes a plate-out phenomenon on the roll metal surface during the molding process of composite materials and causes a delay in gelation time, and as the content increases, the above phenomenon becomes more severe. As mentioned above, it is desirable that the amount is as small as possible.

としての高分子樹脂との結着力が高く、かつ高比重であ
るため面密度の大きな遮音材用として有用である。As mentioned above, the filler according to the present invention has a high binding force with a polymer resin as a binder and has a high specific gravity, so it is useful as a sound insulating material with a large areal density.
したがって、このフィラーを利用した複合材は従来捷案
されているものに比べ成形加工性が傍れ、しかも大量の
フィラーを充填しても優れた柔軟性を有するので遮音材
としての実用性が高い。Therefore, composite materials using this filler have better moldability than conventionally developed materials, and have excellent flexibility even when filled with a large amount of filler, making them highly practical as sound insulation materials. .
