る。DETAILED DESCRIPTION OF THE INVENTION Recently, noise has been brought into focus as a type of pollution, and people's interest in noise prevention is increasing. Although the basic idea is to reduce noise by improving the source, in many cases it is difficult to deal with noise at the source, so soundproofing technology has started to attract more and more attention. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, which will be described below, relates to an inexpensive soundproofing material made of plastic and a composite material of plastic and iron.

ないなどの問題がある。 On the other hand, products with iron powder added have problems such as the iron powder exposed on the surface oxidizing and rusting, and the adhesive strength between the iron powder and the vinyl chloride resin being insufficient.
Furthermore, it is not economical to apply plating or surface treatment to iron powder, and iron powder is not necessarily inexpensive in the first place.

れる。 Therefore, in the present invention, in order to eliminate the above-mentioned drawbacks, it was decided to use powdered steelmaking slag, which is a by-product of the steelmaking process, as a filler. As for steelmaking slag, for example, the composition of current converter slag is [CaO50, SiO2 14,
FeO15, Fe 2 O 3 8, MgO7, MnO5, etc. (numbers are %)], and the density is about 4 among various slags.
It is characterized by its high g/cm 2 . However, in addition to this, some electrical steelmaking slags are high-density slags produced when hot metal is pretreated to remove silicon and phosphorus, and these are also treated as steelmaking slags.

た理由は以下の通りである。 Vinyl chloride resin is one of the most widely used resins because it is inexpensive and has good mechanical properties.
In addition, vinyl chloride resin is used as the base resin because it has stronger polarity than polyethylene, which forms the double wall of general-purpose resin, and has superior adhesion to fillers and steel plates.It also has high density and excellent flame retardancy. It was to be. However, the present invention includes other materials such as vinylidene chloride resin and a copolymer with vinyl acetate, but these resins maintain the characteristics of vinyl chloride resin and have improved adhesive strength and moldability. This is because it has some advantages. Also, since the product is required to be flexible, it was decided to add a plasticizer to soften it. Steelmaking slag powder, which is a by-product oxide, was added to this, and the reason for using these powders is as follows.

ートの密度が不十分であり、製品の面密度を高め

性、経済性などの点で問題が生ずるからである。 Firstly, these powders are very cheap as they are by-products of the steel manufacturing process, and since they are already in a certain amount of powder or extremely fine powder, they can be made into the desired material with a small cost for crushing, sieving, etc. It becomes a powder. Secondly, they are in an ionic bond state and have good adhesion to vinyl chloride resins, which have strong ionic bonding factors. This is a necessary property in order to obtain a dense product by adding as much filler as possible without significantly deteriorating the mechanical properties. Third, although these powders are lighter than iron powder, they all have a high density compared to calcium carbonate, which satisfies the essential conditions for improving soundproofing properties. The density of these fillers is 3.5
g/cm 3 or more, but if it is less than this, the product sheet density will be insufficient, and in order to increase the product's areal density, the sheet thickness must be increased, resulting in problems such as workability and economic efficiency. This is because problems arise.

接着性の富んでいるためであると考えられる。 Sound insulation properties are roughly determined by the mass law, and the greater the weight per unit area, the better the properties. Therefore, the key point in development is how much heavy filler can be added to the resin. In the present invention, the amount added is limited to 500 parts or more and 1500 parts or less per 100 parts of vinyl chloride resin. Considering that the amount conventionally used as a filler is less than 100 parts, and most are less than 30 parts, this addition amount is extremely large. The reason for excluding the additive amount of less than 500 parts is that with such an additive amount, the sheet quality will not be that high, the sound insulation properties will be insufficient unless the sheet thickness is increased, and the amount of resin required will be large, resulting in high cost. by. The reason why the amount is limited to 1,500 parts or less is to avoid a decrease in mechanical properties, especially tensile strength and elongation, and difficulty in molding due to a decrease in fluidity during kneading. But filler 1500
The fact that this filler has sufficient mechanical properties to withstand use even when it is added up to 50% is due to its superior adhesion to vinyl chloride resins compared to pure metals such as lead and iron. This is thought to be due to the
第１図に塩化ビニール樹脂100部、可塑剤

変化を示した。これからみると同一容積の充填剤
を添加した場合に鉄粉と比べて転炉スラグの方が
機械的性質の劣化が少ないことがわかる。 Figure 1 shows the basic composition of 100 parts of vinyl chloride resin, 70 parts of plasticizer (DOP+TCP), 5 parts of stabilizer, etc., and to this, varying amounts of converter slag and iron powder are added to create a 1 mm thick sheet. The tensile strength and elongation were measured to show the changes in mechanical properties depending on the amount added. From this, it can be seen that when the same volume of filler is added, the mechanical properties of converter slag deteriorate less than iron powder.
このことは転炉スラグの方が鉄粉と比べて塩化
ビニール樹脂との接着性が優れていることの現れ
である。したがつて樹脂中への大量添加が鉄粉よ
りも容易にできることになり本発明の主張点の一
つである。 This is an indication that converter slag has better adhesion to vinyl chloride resin than iron powder. Therefore, it can be added to the resin in large quantities more easily than iron powder, which is one of the main points of the present invention.
本発明では充填剤のサイズについては特に限定
していないが、100メツシユ以下、好ましくは200
メツシユ以下がよい。粉末サイズが大きいと良好
な表面性状がえがたいし、機械的性質も劣化す
る。小さすぎると粉砕にコストがかゝるほか混練
成形もむずかしくなる。 In the present invention, the size of the filler is not particularly limited, but it is 100 mesh or less, preferably 200 mesh or less.
It is better to use less than 100 yen. If the powder size is large, it is difficult to obtain good surface properties and the mechanical properties also deteriorate. If it is too small, grinding becomes costly and kneading and molding becomes difficult.

比率を高めた方がよい。この目的のためには
TCP、塩素化ポリエチレンなどが適当である。 In the present invention, a plasticizer is added to soften the soundproofing material in order to provide good workability and soundproofing properties, but the reason why the plasticizer is set at 50 parts or more and 150 parts or less per 100 parts of vinyl chloride resin. is as follows. If the amount is less than 50 parts, the product will not have sufficient softness, will be difficult to mold, and will have insufficient sound insulation and vibration damping properties. Moreover, if it exceeds 150 parts, the cost will increase, the advantage of using inexpensive fillers will be reduced, and the flame retardance will deteriorate. The most commonly used plasticizers, such as di-2-ethylhexyl phthalate (DOP) and tricresyl phosphate (TCP), can be used, but considering that this sheet will be used in the construction field, it should be made as flame-retardant as possible. It is better to use a higher proportion of flame-retardant plasticizers to increase the degree of flame retardant plasticizer used. For this purpose
TCP, chlorinated polyethylene, etc. are suitable.
その他にも通常の塩化ビニール系樹脂に添加さ
れている安定剤、紫外線吸収剤、着色剤などが添
加されるのはもちろんである。以上の配合によつ
てできた製品の密度は2.5g/cm3、望ましくは３g/
cm3以上になる。 Of course, other stabilizers, ultraviolet absorbers, colorants, etc. that are added to ordinary vinyl chloride resins are also added. The density of the product made from the above formulation is 2.5g/cm 3 , preferably 3g/cm 3 .
cm3 or more.
本発明の製品の製造法は通常の塩化ビニールシ
ートの製法と同じであつて、カレンダー加工か、
ダイからの押出しによるが摩耗の問題があるので
加工機械の材質面からの検討が必要である。 The manufacturing method of the product of the present invention is the same as that of ordinary vinyl chloride sheets, including calendering,
Although it is extruded from a die, there is a problem of wear, so it is necessary to consider the material of the processing machine.
塩化ビニール系樹脂はもともと難燃性ではある
が、これに上記量の無機物を添加すれば難燃性は
一層の向上をみることになり建築材料としてより
適切なものになる。更にこれだけの製鋼スラグを
添加すると静電防止に役立つこともわかつた。 Vinyl chloride resin is inherently flame retardant, but if the above amount of inorganic material is added to it, the flame retardance will be further improved, making it more suitable as a building material. Furthermore, it was found that adding this amount of steelmaking slag helps prevent static electricity.
製鋼スラグは黒色系であり、これらを添加して
できた製品の色調は暗く、直接人目にふれるとこ

場合がある。そこでこのような用途向けには通常
行なわれている方法で着色もしくは模様の入つた
薄い塩化ビニールシートやアクリルシートをはり
合わせることも可能である。美観上から使用する
前述のシートの厚さは性能とコスト面から考えて
250μ程度以下が望ましい。又アクリルシートを
含めた理由は色調がきれいであること、屋外に使
う場合に紫外線に強いことによる。したがつて目
的に応じてこれらのシートを選択すればよい。 Steelmaking slag is black in color, and products made by adding these slags have a dark color, and from an aesthetic point of view, it may be undesirable to use them in areas where they will be seen directly by the public. Therefore, for such uses, it is also possible to glue together colored or patterned thin vinyl chloride sheets or acrylic sheets using the usual methods. The thickness of the sheet mentioned above, which is used for aesthetic reasons, is determined from the viewpoint of performance and cost.
It is desirable that the thickness be about 250μ or less. The reason for including acrylic sheet is that it has a beautiful color tone and is resistant to ultraviolet rays when used outdoors. Therefore, these sheets may be selected depending on the purpose.

で省エネルギー的用途にも向く。 The vinyl chloride sheet added with a large amount of filler has been described above, but in the present invention, this sheet can be used by hanging it like a curtain, or directly attached to a plywood or steel plate for soundproofing purposes. It is also possible to use this as a composite steel plate by bonding it to a thin steel plate in advance. In other words, the vinyl chloride sheet alone lacks rigidity and cannot be used alone for home appliance materials or building materials, such as room partitions. However, when the above-mentioned sheet is glued to a thin steel plate, it not only has the necessary rigidity due to the rigidity of the steel plate, but also has the strength of the steel plate as a backing, so the strength itself is not required as much, and the filler The amount of addition can be increased, further improving sound insulation properties and reducing costs. Also, since the steel plate blocks ultraviolet rays, deterioration of the vinyl chloride resin due to ultraviolet rays can be prevented. Furthermore, rather than having to be glued onto a steel plate by each individual user at the time of use, a certain level of quality can be guaranteed by gluing the steel plate in advance, and processing and construction can be simplified and labor-saving can be achieved. On the other hand, from the steel plate side, not only does the rigidity increase to some extent, but the increased weight per unit area also improves the sound insulation to a certain extent, and the vibration damping properties of the steel plate itself are also greatly improved. Additionally, it also improves insulation properties, making it suitable for energy-saving applications.

However, from the perspective of sound insulation properties, the overall areal density must be 2.5 kg/m 2 or more. In addition to mild steel sheets, the thin steel sheet can also be applied to surface-treated steel sheets such as colored galvanized iron and galvanized iron sheets, as well as thin stainless steel sheets.

激に劣化することにもとづくものである。 In the composite steel plate of the present invention, the thickness of the vinyl chloride sheet is limited to 0.5 mm or more, but if it is less than this, the sound insulation and vibration damping properties will be insufficient. On the other hand, the thickness of the steel plate was limited to 0.5 mm or less, but if it is thicker than this, the characteristics of the steel plate alone will be too strong, resulting in a decrease in vibration damping performance and a coincidence effect in sound insulation, which will cause the sound insulation performance to become large in a specific frequency range. Since it would not only reduce the width but also increase the cost, it was limited to 0.5 mm or less.
Furthermore, in the present invention, the areal density of the entire composite steel plate is set to 2.5.
Although it is limited to Kg/ m2 , this is based on the fact that the sound insulation properties deteriorate rapidly below this limit.

にかなつているといえる。 Figure 2 shows the relationship between areal density and transmission loss of a composite steel plate in which a soft vinyl chloride sheet containing slag powder and iron powder, and a vinyl chloride sheet containing slag powder are laminated to a steel plate. The solid line shows the mass law. What can be seen from this figure is that the sound insulation properties of a sheet obtained by adding high-density powder to soft vinyl chloride resin are given simply as a function of areal density, regardless of the type of powder, and that it is expected from the mass law. It has the above excellent properties. Therefore, it can be said that a powder that has a relatively high density, good adhesion to resin, and is inexpensive, as in the present invention, is most suitable for the purpose.

の値をもつ。Example 2 A composite steel plate (areal density 6.5 Kg/m 2 ) was manufactured by laminating a 1.5 mm thick sheet made according to the recipe of Example 1 onto a 0.35 mm thick steel plate. The measurement results of the transmission loss are shown in FIG. At low frequencies, the transmission loss is lower than predicted from the mass law, but this is thought to be due to the coincidence effect. However, it shows good sound insulation properties in the high frequency range, which is important from the perspective of human senses. Furthermore, this composite steel plate has not only sound insulation properties but also remarkable vibration damping properties. That is, while the loss coefficient ηmax of a steel plate alone is 9×10 −4 , that of this composite steel plate is 1.5×10 −1 , and its vibration damping properties are about 600 times higher.
