面仕上げ性が低下する。4J and fl are processed into sheets and laid on the floors and walls of automobiles, railway vehicles, and buildings, or adhered to uneven or curved surfaces.
For use as a composite agent laminated with a ll board or nonwoven fabric, it is important that the material has a high areal density, good flexibility, and good moldability. In addition, price, availability of materials, and resistance to deterioration are also important. To improve the sound insulation effect,
It is desirable to increase the areal density as much as possible, that is, to fill as much high-density filler as possible. However, the affinity between binder and filler is mutually related;
If the binder and filler are not properly combined, a plate-out phenomenon will occur during molding, and the surface finish of the product will deteriorate.

シートの機械的性質も十分とは言えない。Recently, a soundproofing material that combines vinyl chloride resin containing plasticizer with iron oxide, a by-product of the steel manufacturing process, has been published in Japanese Patent Application Laid-Open No. 57-34.
It is disclosed in the No. 064 publication. Although this oxide is said to have excellent adhesion to vinyl chloride, it has poor releasability from the roll surface during molding, takes a long time to gel, and the mechanical properties of the resulting sheet are not sufficient.

遮音材である。i! ! ! The present invention provides a sound insulation material formed by mixing vinyl chloride resin as a binder and inorganic powder as a filler, in which (a) the filler contains 50 to 90% by weight of iron oxide;
It is essential to have a composition of 10 to 30% by weight of silica and a total of 10% by weight or less of alkali or alkaline earth metal oxides, (b
) The flexible sound insulating material is formed by mixing 200 to 1700 parts of the filler with 100 parts of the binder and molding the filler.
以下により詳しく内容を説明する。The details will be explained in more detail below.
本発明の遮音材の基本成分は、塩化ビニルと無機系粉末
である。機能的には前者はバインダー、後者はフィラー
と称される。The basic components of the sound insulation material of the present invention are vinyl chloride and inorganic powder. Functionally, the former is called a binder, and the latter is called a filler.
本発明で使用のフィラーは、特にその構成成分と割合が
重要である。即ちフィラーは、酸化鉄４０〜８５ｗｔ％
と。The filler used in the present invention is particularly important in terms of its constituent components and proportions. That is, the filler contains 40 to 85 wt% iron oxide.
and.
シリカが少なくとも１０ｗｔ％以上、一方アルカリ又は
アルカリ土類金属の酸化物の合計が１０ｗｔ％以下の構
成である。残部組成には特に制限は無い。The composition has a composition in which silica is at least 10 wt % or more, and the total amount of alkali or alkaline earth metal oxides is 10 wt % or less. There are no particular restrictions on the composition of the remainder.

。Iron oxide is FeO+ Fetuss Fe>O,, Fed
” Includes those existing in various forms of Fe, O, and nFeO・5in2 (n is 1 to 3).In particular, nFeO・
Iron oxide, which exists as SiO2, is F in normal quantitative analysis.
Since eO and Sin can be quantified separately, FeO is herein referred to as iron oxide. The proportion of iron oxide to the total filler is in the range of 50 to 9 wt%. If the proportion of iron oxide is low, sufficient sound absorption properties cannot be exhibited. The upper limit is determined based on the necessity of containing silica, which is another essential component.

を発揮する。前記酸化鉄フィラーを大量に充填する見地
から、シリカはフィラー中に少なくとも１０ｗｔ％以上
、好ましくは１０〜３０ｗｔ％存在するのが好ましい。Another essential component as a filler is silica. The bulk specific gravity of this component itself is around 0.1, which is smaller than that of iron oxide, which is 4 to 6, so silica does not help improve areal density, but its presence allows iron oxide to be filled. It has the effect of significantly increasing the thickness of the product, preventing the plate-out phenomenon during molding, shortening the gelling time, and improving the smoothness of the product. From the viewpoint of filling a large amount of the iron oxide filler, it is preferable that silica is present in the filler in an amount of at least 10 wt% or more, preferably 10 to 30 wt%.

い。In addition to SiO2, silica is nFeO-5i○,, nFao
- Any form of Fe2O3.SiO (n=1 to 3) or silica alumina may be used. For example, a catalyst for catalytic cracking of petroleum is preferably a silica-alumina powder. Silica may be contained in large amounts, but as mentioned above, it limits the content of iron oxide and has a low density, so it is not preferable to use a large amount, so the upper limit is 30 wt%.
In particular, iron-making slag produced as a by-product in the copper smelting process containing nFao-3io□ as a main component is most preferable as a filler.

The smaller the amount of g O and Ca O, the better, and the upper limit is 10w.
It should be limited to t% or less, preferably 5wt% or less. If a large amount of this oxide is present, a plate-out phenomenon will occur on the roll metal surface during molding, and the gelation time will be delayed.Furthermore, the presence of this component inhibits the effect of silica.

である。An example of a filler that satisfies the above composition is pine 1~ obtained from a flash furnace in the copper refining process, added with Sin and oxygen in a converter, silicate and oxidized, and the resulting slab is subjected to magnetic separation. This is so-called iron concentrate slag, which is obtained by flotation of the obtained slab and dehydration of the residue after recovering the copper concentrate.

t%, Fe2035wt%, Mg05% or less, and contains almost no CaO, that is, it contains sufficient iron oxide and silica, while containing almost no alkali metal oxide. Since the composition is a by-product of the copper refining process, it is inexpensive and produced in large quantities. Moreover, since it has undergone flotation, it is originally crushed particles. This slag has a bulk density of 3 to 4゜↓゛ (specific gravity of 5 to 5.5), so it can be said to be a preferable filler.Since moisture in the filler causes foaming during the molding process, 3wt% or less, It is preferably used after drying to a concentration of 2 wt% or less, particularly preferably 1 wt% or less.

As described in Publication No. 06, iron oxide 25wt%, silica 1
In addition to 2 wt%, it contains about 37 wt% of CaO, and its composition is completely different from that of the iron concentrate slag generated in the copper smelting process.
