本発明に係るシート状物、及び、シート状物の製造方法によれば、油膜が付着した場合でも、滑り抵抗の低下を抑制することが可能となる。 According to the sheet-like material and the method for producing the sheet-like material according to the present invention, it is possible to suppress a decrease in slip resistance even when an oil film adheres.
まず、図１から図４を用いて、本実施形態に係るシート状物１の構成を説明する。シート状物１は、一の面である表側面１ａと、他の面である裏側面１ｂと、を有して、二液混合性ポリウレアである常温硬化性ポリウレアで形成される。本実施形態において、シート状物１は、裏側面１ｂを工場内の床面に接地させて使用する、歩行者用滑り止めシートとして構成されている。但し、シート状物１を他の用途に用いても差し支えない。 First, the configuration of the sheet-shaped object 1 according to the present embodiment will be described with reference to FIGS. 1 to 4. The sheet-like material 1 has a front side surface 1a which is one surface and a back side surface 1b which is the other surface, and is formed of a room temperature curable polyurea which is a two-component mixed polyurea. In the present embodiment, the sheet-like object 1 is configured as a non-slip sheet for pedestrians, which is used by grounding the back side surface 1b to the floor surface in the factory. However, the sheet-like material 1 may be used for other purposes.
図１及び図２に示す如く、表側面１ａには、表側面１ａの側に突出する多数の凸部２が形成されている。図３に示す如く、裏側面１ｂには、凸部２に対応する箇所（凸部２の裏側）に凹部３が形成される。また、図４に示す如く、凸部の表面を含む表側面１ａには、全体的に微小な凹凸形状Ｇが形成されている。 As shown in FIGS. 1 and 2, a large number of convex portions 2 protruding toward the front side surface 1a are formed on the front side surface 1a. As shown in FIG. 3, a concave portion 3 is formed on the back surface surface 1b at a portion corresponding to the convex portion 2 (the back side of the convex portion 2). Further, as shown in FIG. 4, a minute uneven shape G is formed on the front side surface 1a including the surface of the convex portion as a whole.
本実施形態に係るシート状物１において、凹凸形状Ｇの凹形状と凸形状との高さの差は、ポリウレアの噴霧により形成可能という理由で、０．３ｍｍ〜０．５ｍｍとなるように形成されている。また、シート状物１において、凸部２は周囲からの突起高さが、強度と原料コストのバランスという理由で１．０ｍｍ〜５．０ｍｍとなるように形成されている。 In the sheet-like object 1 according to the present embodiment, the height difference between the concave shape and the convex shape of the concave-convex shape G is formed to be 0.3 mm to 0.5 mm because it can be formed by spraying polyurea. Has been done. Further, in the sheet-like object 1, the convex portion 2 is formed so that the height of the protrusion from the periphery is 1.0 mm to 5.0 mm because of the balance between strength and raw material cost.
本実施形態に係るシート状物１は、多数の凹部が形成された基面に、それぞれ独立した原料供給ホースから供給されたイソシアネート基を有する化合物と、アミノ基を有する硬化剤とを衝突混合スプレーガンとを吹き付けることにより、基面に常温硬化性ポリウレアの層を形成する。そして、表側面１ａの側に多数の凸部２を突出させ、さらに、凸部２の表面に微小な凹凸形状Ｇを形成する。 In the sheet-like material 1 according to the present embodiment, a compound having an isocyanate group supplied from an independent raw material supply hose and a curing agent having an amino group are collision-mixed and sprayed on a base surface on which a large number of recesses are formed. By spraying with a gun, a layer of room temperature curable polyurea is formed on the base surface. Then, a large number of convex portions 2 are projected on the side of the front side surface 1a, and a minute uneven shape G is further formed on the surface of the convex portions 2.
ポリウレア樹脂層は、イソシアネートと、アミノ基を有する硬化剤とがウレア結合して生成される。イソシアネートと硬化剤との反応は非常に早く、数秒で接触硬化するため、基面の表面にイソシアネートと硬化剤とを衝突混合スプレーガンで塗布すれば、直ちに所定厚さのポリウレア樹脂層が形成される。 The polyurea resin layer is formed by a urea bond between isocyanate and a curing agent having an amino group. The reaction between the isocyanate and the curing agent is very fast, and the contact cures in a few seconds. Therefore, if the isocyanate and the curing agent are applied to the surface of the base surface with a collision mixing spray gun, a polyurea resin layer having a predetermined thickness is immediately formed. To.
イソシアネート基を有する化合物としては、例えば、芳香族イソシアネート、脂環式イソシアネート、脂肪族イソシアネート、芳香族イソシアネートの水添物等が挙げられる。より具体的には、例えば、トリレンジイソシアネート（ＴＤＩ）、ジフェニルメタン−４，４’−ジイソシアネート（ＭＤＩ）、１，５−ナフタレンジイソシアネート（ＮＤＩ）等のジイソシアネート、多価アルコールとジイソシアネートとの付加体（アダクト）、イソホロンジイソシアネート、ヘキサメチレンジイソシアネート等が挙げられる。また、イソシアネート基を有する化合物は、イソシアネート基を一次的に保護基で保護して不活性にしたブロック化イソシアネートであってもよい。保護基は熱等によって除去され、イソシアネート基を再生させて使用することができる。保護基となり得る保護剤は、例えば、フェノール、カプロラクタム、オキシム、アルコール等が挙げられる。アミノ基を有する硬化剤としては、ポリアミン等が挙げられる。ポリアミンは、アミノ基を２つ以上有する化合物であればよい。 Examples of the compound having an isocyanate group include aromatic isocyanates, alicyclic isocyanates, aliphatic isocyanates, and hydrogenated products of aromatic isocyanates. More specifically, for example, diisocyanates such as toluene diisocyanate (TDI), diphenylmethane-4,4'-diisocyanate (MDI), 1,5-naphthalenedisocyanate (NDI), and adducts of polyhydric alcohols and diisocyanates ( Adduct), isophorone diisocyanate, hexamethylene diisocyanate and the like. Further, the compound having an isocyanate group may be a blocked isocyanate in which the isocyanate group is primarily protected by a protecting group to inactivate it. The protecting group is removed by heat or the like, and the isocyanate group can be regenerated and used. Examples of the protective agent that can be a protecting group include phenol, caprolactam, oxime, alcohol and the like. Examples of the curing agent having an amino group include polyamines and the like. The polyamine may be a compound having two or more amino groups.
より詳細には、基面に常温硬化性ポリウレアを吹き付けることにより、一方の面の側に多数の凸部が突出したシート素材を形成する（シート素材形成工程）。そして、基面からシート素材を剥離し（剥離工程）、その後、シート素材における一方の面（凸部が突出した面）に常温硬化性ポリウレアを噴霧する（噴霧工程）ことにより、凸部の表面に凹凸形状が形成されたシート状物１が形成される。 More specifically, by spraying a room temperature curable polyurea on the base surface, a sheet material having a large number of protrusions protruding on one surface side is formed (sheet material forming step). Then, the sheet material is peeled from the base surface (peeling step), and then room temperature curable polyurea is sprayed on one surface (the surface on which the convex portion protrudes) of the sheet material (spraying step) to obtain the surface of the convex portion. A sheet-like object 1 having an uneven shape is formed on the surface.
なお、硬化性樹脂の硬化は、熱硬化性樹脂の熱処理硬化、二液混合による常温硬化、一液湿気硬化の何れかを採用することができる。また、硬化前に加温処理するものであっても良い。また、硬化性樹脂は、無溶剤系、有機溶剤系、水系いずれであっても良い。このうち、環境面、安全性、施工性という理由で無溶剤の二液混合による常温硬化が望ましい。ポリウレアとしてはＮＵＫＯＴＥ社製のＮＵＫＯＴＥ ＳＴ、２液混合硬化型、加温吹付けタイプの芳香族系ポリウレアを使用した。 As the curing of the curable resin, any one of heat treatment curing of the thermosetting resin, normal temperature curing by two-component mixing, and one-component moisture curing can be adopted. Further, it may be heated before curing. The curable resin may be solvent-free, organic solvent-based, or water-based. Of these, room temperature curing by solvent-free two-component mixing is desirable from the viewpoint of environment, safety, and workability. As the polyurea, NUKOTE ST manufactured by NUKOTE, a two-component mixture curing type, and a heating spray type aromatic polyurea were used.
シート状物１の厚さは、強度と原料コストのバランスという理由で１．５〜２．５ｍｍの範囲内とすることが望ましい。特に、１．５ｍｍより薄くなると、凸部頂点が薄くなり、凸部が破損し易くなるという点で問題になる。また、シート状物１の大きさは生産効率及び重量が増加するために輸送が困難になるという理由で、１ｍ×２ｍ以下とすることが望ましい。なお、シート状物１は、シート単独で用いてもよく、別の基材に積層して積層シートとして用いてもよい。また、粘着層を設けてテープとして用いてもよい。 The thickness of the sheet-like material 1 is preferably in the range of 1.5 to 2.5 mm because of the balance between strength and raw material cost. In particular, if it is thinner than 1.5 mm, the apex of the convex portion becomes thin, and the convex portion is easily damaged, which is a problem. Further, the size of the sheet-like material 1 is preferably 1 m × 2 m or less because transportation becomes difficult due to an increase in production efficiency and weight. The sheet-like material 1 may be used as a single sheet or may be laminated on another base material and used as a laminated sheet. Further, an adhesive layer may be provided and used as a tape.
シート状物１において、凸部２の形状は、本実施形態における半球形型以外にも、三角刑型、方形型等の他の形状を採用することができる。但し、凸部２の加工容易性から、本実施形態の如く半球型とすることが望ましい。また、凸部２の間隔は、金型からの離型性、人間の足の裏に接触できる凸部２の個数バランスという理由で、３０〜３５ｍｍの範囲内とすることが望ましい。 In the sheet-like object 1, as the shape of the convex portion 2, other shapes such as a triangular penal shape and a square shape can be adopted in addition to the hemispherical shape in the present embodiment. However, from the viewpoint of ease of processing the convex portion 2, it is desirable to make the convex portion 2 hemispherical as in the present embodiment. Further, the distance between the convex portions 2 is preferably within the range of 30 to 35 mm because of the releasability from the mold and the balance of the number of convex portions 2 that can come into contact with the soles of human feet.
シート状物１は、例えば油膜を張りやすい工場の床及び足場や、乗り物の乗り場、階段の踊り場に用いられる。特に不特定多数のものに踏まれるという理由で、乗り物の乗り場用シートに適する。 The sheet-like object 1 is used, for example, as a floor and scaffolding of a factory where an oil film is easily formed, a vehicle landing, and a landing of stairs. It is particularly suitable as a landing seat for vehicles because it can be stepped on by an unspecified number of people.
次に、図５を用いて、本願出願人が行ったＣ．Ｓ．Ｒ測定試験について説明する。Ｃ.Ｓ.Ｒ測定試験とは、ＪＩＳＡ１４５４で定められる床材の滑り性試験によって滑り抵抗係数を測定する試験である。日本建築学会の推奨値によれば、履物を履いて動作する床においてＣ.Ｓ.Ｒ値が０．４以上であることが目安とされている。 Next, using FIG. 5, the C.I. S. The R measurement test will be described. The CSR measurement test is a test for measuring the slip resistance coefficient by the slip property test of the floor material defined by JIS A1454. According to the recommended value of the Architectural Institute of Japan, it is a guideline that the CSR value is 0.4 or more on the floor that operates with footwear.
図５に示す如く本試験は、前記実施形態に係るシート状物１（厚さが２．０ｍｍで、表側面１ａの側に突出する多数の凸部２（周囲からの突起高さが３．５ｍｍ）が形成され、表側面１ａに全体的に微小な凹凸形状Ｇ（凹凸形状における高さの差が０．３ｍｍ）が形成されたもの）を実施例として行った。また、比較例１として、凸部２を形成せずに凹凸形状Ｇのみを形成したシート状物を採用した。また、比較例２として、縞鋼板を採用した。また、本試験は、それぞれの測定対象について、乾燥状態、湿潤状態、及び、グリース（ＡＺシャーシーグリース）を塗布した状態、の三つの状態について行った。 As shown in FIG. 5, in this test, the sheet-like object 1 according to the embodiment (thickness is 2.0 mm, and a large number of convex portions 2 protruding toward the front side surface 1a (the height of protrusions from the periphery is 3.). 5 mm) was formed, and a minute uneven shape G (a height difference in the uneven shape of 0.3 mm) was formed on the front side surface 1a as an example. Further, as Comparative Example 1, a sheet-like material in which only the concave-convex shape G was formed without forming the convex portion 2 was adopted. Further, as Comparative Example 2, a striped steel plate was adopted. In addition, this test was carried out for each measurement target in three states: a dry state, a wet state, and a state in which grease (AZ chassis grease) was applied.
図５に示す如く、比較例２（縞鋼板）においては、乾燥状態において０．８４というＣ．Ｓ．Ｒ測定値を得ることができたが、湿潤状態及びグリース塗布状態で０．３８という、前記推奨値よりも低い結果となった。また、比較例１（凹凸形状のみ）においては、乾燥状態において０．７１、湿潤状態で０．５７というＣ．Ｓ．Ｒ測定値を得ることができたが、グリース塗布状態で０．２５という、前記推奨値よりも低い結果となった。即ち、図５中に※印を記入した箇所については、日本建築学会の推奨値を下回る結果となった。 As shown in FIG. 5, in Comparative Example 2 (striped steel plate), C.I. S. Although the R measurement value could be obtained, the result was 0.38 in the wet state and the grease-applied state, which was lower than the recommended value. Further, in Comparative Example 1 (concavo-convex shape only), C.I., 0.71 in the dry state and 0.57 in the wet state. S. Although the R measurement value could be obtained, the result was 0.25 in the grease-applied state, which was lower than the recommended value. That is, the parts marked with * in Fig. 5 were below the recommended values by the Architectural Institute of Japan.
一方、本実施例に係るシート状物１によれば、図５に示す如く、乾燥状態において０．７７、湿潤状態で０．６０、グリース塗布状態で０．５６と、何れも前記推奨値を上回る結果となった。このように、本実施形態に係るシート状物１、及び、シート状物１の製造方法によれば本試験により、表面に油膜が付着した場合でも滑り抵抗の低下を抑制することが可能となることが明らかとなったのである。 On the other hand, according to the sheet-like material 1 according to the present embodiment, as shown in FIG. 5, the recommended values are 0.77 in the dry state, 0.60 in the wet state, and 0.56 in the grease-applied state. The result exceeded. As described above, according to the sheet-like material 1 and the method for producing the sheet-like material 1 according to the present embodiment, it is possible to suppress a decrease in slip resistance even when an oil film adheres to the surface by this test. It became clear.
