振マットに利用できる粉末ゴムを利用したゴムマットの
製造方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a powder that can be used for golf course cart and walking path mats, floor mats in greenhouses, mats for cowsheds and pig pens, and further anti-vibration mats for railways. This invention relates to a method of manufacturing a rubber mat using rubber.
従来から粉末ゴムを利用したゴムマットが用いられてお
り１．牛舎や豚舎等のマット、ガスボンベの敷物等の重
量物支持用とされている。Conventionally, rubber mats made of powdered rubber have been used.1. It is used to support heavy objects such as mats in cowsheds and pigpens, and gas cylinder rugs.
このゴムマットは一般には粉末ゴムにバインダーを混ぜ
、これをモールド内に入れて加硫されている。従って、
出来上がった製品はその表面には粉末ゴムが剥き出しに
なるため、外観のみならず耐久性が極端に悪いものであ
った。This rubber mat is generally made by mixing powdered rubber with a binder, placing the mixture in a mold, and vulcanizing it. Therefore,
Since the powdered rubber was exposed on the surface of the finished product, not only the appearance but also the durability was extremely poor.
更に、例えば特開昭４９−３１７７３号では表面にゴム
シートを張り合せて一体に成形加硫する方法も提案され
ている。しかし、これはいずれもカレンダーロールにて
前もってシート状にされているものを使用するため製品

たこのゴムシートと粉末ゴムのシートとの間に存在する
空気は、一体成形中に外に抜けないため空気がそのまま
取り込まれ、いわゆるエアー溜りが出来る欠点があった
。Furthermore, for example, Japanese Patent Laid-Open No. 49-31773 proposes a method in which a rubber sheet is laminated on the surface and integrally molded and vulcanized. However, since all of these products use sheets that have been previously formed into sheets using calender rolls, the products themselves are relatively soft and are not suitable for heavy rugs. Furthermore, since the air existing between the rubber sheet and the powdered rubber sheet does not escape to the outside during integral molding, the air is taken in as is, resulting in the formation of so-called air pockets.
本発明は上記事実を考慮し、エアー溜りがなく外観及び
耐久性に優れたゴムマットを得る製造方法を提供するこ
とを目的としている。In consideration of the above facts, the present invention aims to provide a manufacturing method for obtaining a rubber mat that is free from air pockets and has excellent appearance and durability.
前記の目的を達成するために、本発明はモールド内にバ
インダーを充填した粉末ゴムの層と、多数の穴を穿った
表面材用の未加硫ゴムシート層とを隣接形成し、これら

トの製造方法に係るものである。In order to achieve the above object, the present invention adjoins a powder rubber layer filled with a binder and an unvulcanized rubber sheet layer for a surface material with a large number of holes perforated in a mold, and then vulcanizes them. The present invention relates to a method for manufacturing a rubber mat, which is characterized in that it is integrated under pressure heating.
そしてこの場合、表面材用の未加硫ゴムシートは、バイ
ンダーを充填した粉末ゴム層の片面に隣接形成すること
も、更には場合によってはその両面に形成してもよいこ
とは勿論である。In this case, it goes without saying that the unvulcanized rubber sheet for the surface material may be formed adjacent to one side of the powder rubber layer filled with the binder, or even on both sides thereof depending on the case.
ここで使用される粉末ゴムは、タイヤその他の加硫済の
ゴム製品を粉末状にしたものが主であって、その粒度は
自由ではあるが、製品の目的によって一般には１〜２ｍ
／ｍ程度の大きさがよい。The powder rubber used here is mainly powdered tires and other vulcanized rubber products, and although the particle size is free, it is generally 1 to 2 m depending on the purpose of the product.
A size of about /m is good.
また、前記の粉末ゴムに混合されて用いられるバインダ
ーは、ＳＢＲ，ＮＲ，ＮＢＲ系のゴム、硫黄、ウレタン
樹脂、エポキシ樹脂、エチレン−酢酸ビニル共重合体等

末ゴム１０ｋｇに対して、２００〜３００ｇ程度が使用
される。Further, the binder used by being mixed with the powdered rubber is appropriately selected from SBR, NR, NBR rubber, sulfur, urethane resin, epoxy resin, ethylene-vinyl acetate copolymer, etc. In this case, about 200 to 300 g is used per 10 kg of the powdered rubber.
一方、未加硫ゴムシートは、特に制限がなく、これもマ

一般にはカレンダーロールにて５５〜９０℃の条件下毎
分５〜８ｃｍのスピードで押し出される。On the other hand, there are no particular restrictions on the unvulcanized rubber sheet, and various rubbers are selected depending on the product intended for the mat.
Generally, it is extruded using calender rolls at a speed of 5 to 8 cm per minute under conditions of 55 to 90°C.
そしてこの未加硫ゴムシートは、製品の両面に必ずしも
存在する必要はなく、場合によってはその一方側の面に
あれば十分な場合もある。This unvulcanized rubber sheet does not necessarily need to be present on both sides of the product; in some cases, it may be sufficient to have it on one side.
また、この未加硫ゴムシートには沢山の穴が開けられて
いるものであって、例えば直径約３〜５ｍ／ｍ程度の穴
であり、成形時の主として粉末ゴム中から出てくるエア
ー抜きに供される。In addition, this unvulcanized rubber sheet has many holes, for example holes of about 3 to 5 m/m in diameter, which are used to vent air that comes out from the powdered rubber during molding. served.

度と程度。As for the molding (vulcanization) conditions, a layer of unvulcanized rubber sheet and powdered rubber is formed in the mold, and
kg/crI, preferably 170-180kg/cr
1 of pressure is applied, the vulcanization molding temperature is 130 to 180°C, preferably 150 to 170°C, and the vulcanization time is about 20 to 40 minutes.
最終のゴムマットの平面形状を有する下モールド内に、
直径４ｍ／ｍの穴を多数穿った未加硫ゴムシート（厚さ
０．５ｍ／ｍ）を挿入する。In the bottom mold with the planar shape of the final rubber mat,
An unvulcanized rubber sheet (thickness: 0.5 m/m) with many holes of 4 m/m in diameter is inserted.
次いで粒度１．０〜１．５ｍ／ｍの粉末ゴム３８ｋｇに

未加硫ゴムシート上に入れこれを十分率らにならす。Next, 38 kg of powdered rubber with a particle size of 1.0 to 1.5 m/m filled with 900 g of SBR as a binder is placed on the unvulcanized rubber sheet and the mixture is sufficiently smoothed.
そして更に同様の未加硫ゴムシートをこの上に載せて上
モールドを重ね、１７０ ｋｇ／ｃｄの加圧下に一体成

出来上がったゴムマットはその両面に加硫されたゴムシ
