Since the adhesive layer 13 was provided, the adhesive strength was higher than that of Comparative Example 5 provided with the base layer and the adhesive layer. Moreover, since the adhesive force was higher in Example 3 that did not include the underlayer than Comparative Example 5 that included the underlayer, according to the present invention, the industry with a simple structure was improved while improving the adhesive force. It was found that a roll for use can be realized.
- Example 4 The roll of Example 4 was manufactured under the same conditions as Example 3 in which the coating material was an epoxy resin, but the raw material of the coating material 14 (cylinder for coating material) was replaced with “epoxy resin material mixed with silica powder”. The only difference was that the raw material was a polyurea resin raw material in which polyamine was mixed at a ratio of 80 parts by mass with respect to 100 parts by mass of isocyanate.
- the core material 11, the first adhesive layer 12 made of a material provided in contact with the core material 11 and exhibiting good adhesion to the core material 11, and the first A second adhesive layer 13 made of a material that is provided in contact with one adhesive layer 12 and that exhibits good adhesion to the covering material 14; and in contact with the second adhesive layer 13 It was confirmed that by providing the covering material 14 provided, an industrial roll having a simple structure can be realized while maintaining a high adhesive force between the core material 11 and the covering material 14.

Abstract
Description
まず、実施例1、2及び比較例1~4においては、芯材と被覆材との接着力を比較するために、実機サイズよりも小さいテスト用の小型ロールを作成した。
まず、金属で構成される芯材11を準備した。芯材11は、220mmの外径と、300mmの長さを有する鉄芯であった。
実施例2のロールの製造方法は、基本的には実施例1と同様であったが、第2の接着剤層13を第1の接着剤層12の外表面に接して設ける工程に先立って、第1の接着剤層12を焼付け処理しなかった点において異なっていた。このため、実施例2のロールの第1の接着剤層12は、第2の接着剤層13が形成される前に焼付け処理されたものでなかった。
比較例1のロールの製造方法は、基本的には実施例1と同様であったが、第1および第2の接着剤層12、13を設ける工程を実施しなかった点において異なっていた。このため、比較例1のロールは、芯材11と、この芯材11上に接して設けられた被覆材14とを備えていた。
比較例2のロールは、基本的には実施例1と同様であったが、第1の接着剤を設ける工程を実施しなかった点において異なっていた。このため、比較例2のロールは、芯材11と、この芯材11上に接して設けられた第2の接着剤層13と、この第2の接着剤層13上に接して設けられた被覆材14とを備えていた。
比較例3のロールは、基本的には実施例1と同様であったが、第2の接着剤を設ける工程を実施しなかった点において異なっていた。このため、比較例3のロールは、芯材11と、この芯材11上に接して設けられた第1の接着剤層12と、この第1の接着剤層12上に接して設けられた被覆材14とを備え、第1の接着剤層12は、第2の接着剤層13が形成される前に焼付け処理されたものであった。
比較例4のロールは、基本的には実施例2と同様であったが、第2の接着剤を設ける工程を実施しなかった点において異なっていた。このため、比較例4のロールは、芯材11と、この芯材11上に接して設けられた第1の接着剤層12と、この第1の接着剤層12上に接して設けられた被覆材14とを備え、第1の接着剤層12は、第2の接着剤層13が形成される前に焼付け処理されたものでなかった。
実施例1、2および比較例1~4のロールについて、芯材11と被覆材14との接着力を以下の方法で評価した。図3に示すように、ロールから被覆材14を面長方向に幅10mmで厚さ5mm(鉄芯の表面まで)にカットし、先端を剥離した。その先端をロールの上方に配置した吊り秤に連結した。この状態で、吊り秤を鉛直方向の上方に引っ張って、被覆材14が芯材11から剥離した時の荷重を測定した。その結果を下記の表1に「接着力」として記載する。
実施例1、2:第1の接着剤層と第2の接着剤層との界面
比較例1 :芯材と被覆材との界面
比較例2 :芯材と第2の接着剤層との界面
比較例3、4:第1の接着剤層と被覆材との界面
表1に示すように、芯材11に対して良好な接着性を示す材料で構成された第1の接着剤層12と、被覆材14に対して良好な接着性を示す材料で構成された第2の接着剤層13とを備えていた実施例1および2のロール10については、11N/mm未満の荷重に対して、被覆材14は芯材11から剥離しなかった。
(実施例3)
まず、金属で構成される芯材を準備した。芯材は、400mmの外径と、2400mmの長さを有する鉄芯であった。
まず、金属で構成される芯材を準備した。芯材は、400mmの外径と、2400mmの長さを有する鉄芯であった。
実施例3及び比較例5のロールについて、接着力を以下の方法で評価した。各ロールを被覆層の厚さが1mmになるまで削った。このため、実施例3のロールは、芯材11と、この芯材11上に形成された第1の接着剤層12(厚み約10μm)と、この第1の接着剤層12上に形成された第2の接着剤層13(厚み3mm)と、この第2の接着剤層13上に形成された被覆層(厚み1mm)とを備えていた。また、比較例5のロールは、芯材と、この芯材上に形成された下地層(厚み6mm)と、この下地層上に形成された接着剤層(厚み3mm)と、この接着剤層上に形成された被覆層(厚み1mm)とを備えていた。
実施例3については、800mm以下の高さから落下錘を落下させた時には剥離せず、900mm以上の高さから落下錘を落下させた時には剥離した。剥離箇所は、芯材11と第2の接着剤13との間で、第1の接着剤層12が剥離した。剥離後に観察すると、芯材11と第2の接着剤層13との両方に第1の接着剤層が付着していた。これは、第1の接着剤層が破壊したと考えられる。
(実施例4)
実施例4のロールは、被覆材がエポキシ樹脂の実施例3と同じ条件で製造したが、被覆材14(被覆材用筒体)の原料を、「シリカ粉末を混入したエポキシ樹脂原料」に代えて、「イソシアネート100質量部に対してポリアミンを80質量部の割合で混合したポリウレア樹脂原料」とした点のみ異なっていた。
