Description
本発明は繊維織物を基材として、織物基材に軟質塩化ビニル樹脂層を被覆して得られる、間仕切り、シートシャッター、日除け・雨除け、防水エプロン、防水バッグ、建築養生、フレキシブルコンテナ、フレキシブル水槽、電飾看板、光天井膜などに用いる産業用ターポリン、及びテント倉庫、パビリオン、スポーツ・レジャードーム、プラネタリウムなどの中〜大型のテント膜構造物に用いるターポリンで、ターポリンの表面タックが小さく、これら用途の製品の熱融着縫製工程におけるハンドリング性の良いターポリン関する。 INDUSTRIAL APPLICABILITY The present invention uses a fiber fabric as a base material, and is obtained by coating a soft vinyl chloride resin layer on the textile base material. Partition, sheet shutter, sunshade / rain protection, waterproof apron, waterproof bag, architectural curing, flexible container, flexible water tank Industrial tarpaulins used for lighting signs, light ceiling membranes, etc., and tarpaulins used for medium to large tent membrane structures such as tent warehouses, pavilions, sports / leisure domes, planetariums, etc. It relates to tarpaulins with good handling properties in the heat fusion sewing process of products used.
ジオクチルフタレート（ＤＯＰ）、ジイソノニルフタレート（ＤＩＮＰ）、ジヘプチルフタレート（ＤＨＰ）などのフタル酸ジエステル系可塑剤が多量に配合された軟質塩化ビニル樹脂成形物では表面にタック（ベタつき感）を残し、それによって製品同士がくっ付き、特に薄いフィルムではくっ付いて絡んだフィルムの引き剥がしを困難としている。また、シート製品では経時的に可塑剤が表面に移行（ブリード）して、シートをロール巻きで保管した場合や、重ね置きした状態でブロッキング（癒着）を生じ易く、しかも長期間放置するとシートの引剥しを困難とし、剥がすとブロッキング痕生じて製品の外観を損なう問題があった。またブリードした可塑剤は成型物表面をベトつかせ、これに煤塵や埃が付着することで汚れ易く、しかも汚れが除去し難いものとしていた。これら問題を解決する手段の１つとして特許文献１では、ロール剥離性、耐ブロッキング性などに優れた塩化ビニル系樹脂フィルムとして、１，２−シクロヘキサンジカルボン酸ジイソノニルエステルを可塑剤に使用することが提案されている。しかしブロッキング現象は環境温度、使用状態などで変化し、特に長期に亘る表面タックの改質効果の持続は困難で、可塑剤のブリード（移行）により、表面タックやブロッキングが酷くなるという現状の解決が必ずしもなされていなかった。 Soft vinyl chloride resin moldings containing a large amount of phthalic acid diester plasticizers such as dioctyl phthalate (DOP), diisononyl phthalate (DINP), diheptyl phthalate (DHP) leave a tack (sticky feeling) on the surface. The products stick to each other, especially with thin films, making it difficult to peel off the entangled film. In sheet products, the plasticizer migrates to the surface over time (bleeds), and when the sheets are stored in rolls or when they are stacked, they tend to cause blocking (adhesion). There was a problem that peeling was difficult, and when it was peeled off, blocking marks were generated and the appearance of the product was impaired. In addition, the bleed plasticizer makes the surface of the molded product sticky, and dust and dirt adhere to it, making it easy to get dirty and difficult to remove. As one means for solving these problems, Patent Document 1 discloses that 1,2-cyclohexanedicarboxylic acid diisononyl ester is used as a plasticizer as a vinyl chloride resin film having excellent roll peelability and blocking resistance. Proposed. However, the blocking phenomenon changes depending on the environmental temperature, usage conditions, etc., and it is difficult to maintain the surface tack modification effect over a long period of time, and the current solution is that surface tack and blocking become severe due to plasticizer bleeding. Was not necessarily made.
また、耐ブリード性及び耐ブロッキング性の優れた塩化ビニル樹脂系エラストマー組成物として特許文献２には、塩化ビニル系樹脂及び塩素化ポリエチレンの合計１００重量部に対してＮＢＲ２０〜４００重量部並びに可塑剤１０〜３００重量部を配合した組成物が提案されている。しかしジオクチルフタレート（ＤＯＰ）のみ効果が示され、しかも塩化ビニル樹脂よりも多量のＮＢＲを必要とすることで、可塑剤の耐ブリード性には優れても、ＮＢＲ過多によるタック（ゴム性）が増すことで、これらをシート化したときのシート同士の滑り性を悪くする欠点は避けられないものであった。特に軟質塩化ビニル樹脂製のターポリンで表面がフラットかつ鏡面の透明間仕切りシートでは、重ね置きや巻き取りの状態で互いに密着し易く、温度環境や時間経過によってシート引き剥がしを困難とするブロッキング問題を有していた。このため製造会社は、製品全面にパウダー付着処理した状態でシートをロール巻きするような粉振りを施しているが、ユーザー側には付着パウダーの清拭除去の手間を掛け、しかも使用環境を粉塵汚染するなどの不満を残していた。特にターポリンによる産業資材の製造・縫製の現場では、ターポリン同士の滑りが悪いと高周波ウエルダー機の作業台での取り扱い性が悪く、作業性に影響を及ぼすことがあった。また自走式熱風融着機による長尺のラップ縫製を行う場合に、ターポリン端部の重ね合わせ部の所々に浮きや位置ズレを生じると問題部分ごとに修正の手間をかける必要があった。従って産業資材シート製品の大小に係わらず、タックが小さく、可塑剤ブリードが長期間に亘り極少量に抑止されることで、耐ブロッキング性が持続するような縫製作業の取り扱い性に優れたターポリンが望まれていた。 In addition, as a vinyl chloride resin elastomer composition having excellent bleed resistance and blocking resistance, Patent Document 2 discloses 20 to 400 parts by weight of NBR and a plasticizer based on 100 parts by weight of vinyl chloride resin and chlorinated polyethylene. A composition containing 10 to 300 parts by weight has been proposed. However, only dioctyl phthalate (DOP) has been shown to be effective, and a larger amount of NBR than vinyl chloride resin is required, so that even if the plasticizer is excellent in bleed resistance, tack (rubber property) due to excessive NBR is increased. Thus, the disadvantage of worsening the slipperiness between the sheets when they are formed into sheets is inevitable. In particular, tarpaulins made of soft vinyl chloride resin with a flat and mirror-finished transparent partition sheet tend to adhere to each other in a stacked or rolled-up state, and have a blocking problem that makes it difficult to peel off the sheet over time and over time. Was. For this reason, the manufacturing company gives powder dusting to roll the sheet in a state where the powder adheres to the entire surface of the product. He was dissatisfied with contamination. In particular, at the site of manufacturing and sewing industrial materials using tarpaulins, if the slippage between tarpaulins is poor, the handling property of the work table of the high frequency welder machine is poor, which may affect the workability. In addition, when performing long lap sewing using a self-propelled hot-air fusion machine, it is necessary to take time and effort to correct each problem portion if floating or misalignment occurs in the overlapping portions of the tarpaulin end portions. Therefore, regardless of the size of the industrial material sheet product, the tarpaulin has excellent tackability in sewing work that maintains the anti-blocking property by having a small tack and suppressing the plasticizer bleed to an extremely small amount over a long period of time. It was desired.
本発明は繊維織物を基材として、織物基材に軟質塩化ビニル樹脂層を被覆して得られる、間仕切り、シートシャッター、日除け・雨除け、防水エプロン、防水バッグ、建築養生、フレキシブルコンテナ、フレキシブル水槽、電飾看板、光天井膜などに用いる産業用ターポリン、及びテント倉庫、パビリオン、スポーツ・レジャードーム、プラネタリウムなどの中〜大型のテント膜構造物に用いるターポリンで、タックが小さく、耐ブロッキング効果の持続性に優れたターポリンで、特に上記産業資材、膜構造物などの製造工程における縫製作業時の取り扱い性に優れるターポリンを提供しようとするものである。 INDUSTRIAL APPLICABILITY The present invention uses a fiber fabric as a base material, and is obtained by coating a soft vinyl chloride resin layer on the textile base material. Partition, sheet shutter, sunshade / rain protection, waterproof apron, waterproof bag, architectural curing, flexible container, flexible water tank Industrial tarpaulins used for lighting signs, light ceiling membranes, etc., and tarpaulins used for medium to large tent membrane structures such as tent warehouses, pavilions, sports / leisure domes, planetariums, etc. It is an object of the present invention to provide a tarpaulin that is excellent in sustainability, and that is particularly excellent in handleability during sewing operations in the manufacturing process of the industrial materials and membrane structures.
本発明者は、産業用ターポリンについて上記の現状に鑑みて研究、検討を行った結果、繊維織物を基材として、その少なくとも１面上に軟質塩化ビニル樹脂層が設けられた可撓性積層体において、軟質塩化ビニル樹脂層が塩化ビニル系樹脂１００質量部、及びシクロヘキサンジカルボン酸ジアルキルエステル化合物３０〜８０質量部とを主体に含み、さらに塩素化ポリエチレンを１〜３０質量部含有することによって、タックが小さく、可塑剤ブリードが長期間に亘り極少量に抑止されることで、耐ブロッキング効果の持続を可能とするターポリンが得られることを見出して本発明を完成させるに至った。 As a result of research and examination on industrial tarpaulins in view of the above-mentioned present situation, the present inventor has found that a flexible laminate in which a fiber woven fabric is used as a base material and a soft vinyl chloride resin layer is provided on at least one surface thereof. In which the soft vinyl chloride resin layer mainly contains 100 parts by mass of a vinyl chloride resin and 30-80 parts by mass of a cyclohexanedicarboxylic acid dialkyl ester compound, and further contains 1-30 parts by mass of chlorinated polyethylene. The present invention has been completed by finding that a tarpaulin capable of maintaining the anti-blocking effect can be obtained by suppressing the plasticizer bleed to a very small amount over a long period of time.
すなわち本発明の耐ブロッキング効果持続性ターポリンは、繊維織物を基材として、その少なくとも１面上に軟質塩化ビニル樹脂層が設けられた可撓性積層体であって、前記軟質塩化ビニル樹脂層が塩化ビニル系樹脂１００質量部、及びシクロヘキサンジカルボン酸ジアルキルエステル（〔化１〕の群）３０〜８０質量部とを主体に含み、さらに塩素化ポリエチレンを１〜３０質量部含有することが好ましい。これによって得られるターポリンでは、タックが小さく、可塑剤ブリードを長期間に亘り極少量に抑止することで、耐ブロッキング効果の持続を可能とする。
That is, the anti-blocking effect durable tarpaulin of the present invention is a flexible laminate in which a textile fabric is used as a base material and a soft vinyl chloride resin layer is provided on at least one surface thereof, and the soft vinyl chloride resin layer is It mainly contains 100 parts by mass of a vinyl chloride resin and 30-80 parts by mass of cyclohexanedicarboxylic acid dialkyl ester (group of [Chemical Formula 1]), and further preferably contains 1-30 parts by mass of chlorinated polyethylene. The tarpaulin obtained in this way has a small tack and suppresses the plasticizer bleed to an extremely small amount over a long period of time, thereby enabling the anti-blocking effect to be maintained.
本発明の耐ブロッキング効果持続性ターポリンは、前記軟質塩化ビニル樹脂層がさらに、低分子ポリエステル、芳香族リン酸エステルから選ばれた１種以上の化合物を含み、その併用量が１〜５０質量部であることが好ましい。低分子ポリエステル化合物の併用によって得られるターポリンではタックがより小さく、可塑剤ブリードを長期間に亘り極少量に抑止することで、耐ブロッキング効果の持続を可能とする。また芳香族リン酸エステル化合物の併用によって特に透明な軟質塩化ビニル樹脂層に防炎性を付与し、これによって透明性と透視性を有するターポリンを得ることができ、このターポリンは消防法の防炎規格に適合する間仕切りシートとして屋内外で使用することができる。 In the blocking resistance durable tarpaulin of the present invention, the soft vinyl chloride resin layer further contains one or more compounds selected from low molecular polyesters and aromatic phosphates, and the combined amount thereof is 1 to 50 parts by mass. It is preferable that The tarpaulin obtained by the combined use of the low molecular weight polyester compound has a smaller tack, and the anti-blocking effect can be maintained by suppressing the plasticizer bleed to a very small amount over a long period of time. In addition, the combined use of an aromatic phosphate ester compound provides flame resistance to a particularly transparent soft vinyl chloride resin layer, thereby obtaining a transparent and transparent tarpaulin. It can be used indoors and outdoors as a partition sheet that conforms to the standard.
本発明の耐ブロッキング効果持続性ターポリンは、前記繊維織物が目合空隙率５０〜９５％を有する、２軸織編物、３軸織編物、及び４軸織編物から選ばれた何れか１種の粗目織物であることが好ましい。これによって得られるターポリンは良好な寸法安定性、物性バランス、及び外観意匠性を有する間仕切りシートとして使用することができる。 The blocking resistance durable tarpaulin of the present invention is any one selected from a biaxial knitted fabric, a triaxial woven knitted fabric, and a four-axial woven knitted fabric, in which the fiber woven fabric has a mesh porosity of 50 to 95%. A coarse woven fabric is preferred. The tarpaulin obtained by this can be used as a partition sheet having good dimensional stability, physical property balance, and appearance design.

The tarpaulin thus obtained has good antifouling properties and can be used outdoors for a long time.
本発明の耐ブロッキング効果持続性ターポリンの製造方法は、塩化ビニル系樹脂１００質量部、及びシクロヘキサンジカルボン酸ジアルキルエステル（〔化１〕の群）３０〜８０質量部を主体に含む第一軟質塩化ビニル樹脂熱混練物を準備し、次に前記塩化ビニル系樹脂１００質量部に対し１〜３０質量部の塩素化ポリエチレンを前記第一軟質塩化ビニル樹脂熱混練物に追加配合して得た第二軟質塩化ビニル樹脂熱混練物を用い、この第二軟質塩化ビニル樹脂熱混練物より圧延成型したフィルムを繊維織物の１面以上に積層することで、前記フィルムを軟質塩化ビニル樹脂層とし、前記繊維織物を基材としてなる可撓性積層体を得ることが好ましい。これによって軟質塩化ビニル樹脂層の可塑化を十分かつ均一なものとし、これに塩素化ポリエチレンを後分散させることで、可塑化軟質塩化ビニル樹脂分子鎖に対する塩素化ポリエチレン分子鎖の絡み拘束の状態を効果的とすることで、よりタックが小さく、可塑剤ブリードをより極少量に抑止することで、耐ブロッキング効果、及びその持続をさらに優れたものとする。
The production method of the anti-blocking effect durable tarpaulin of the present invention is the first soft vinyl chloride mainly comprising 100 parts by mass of vinyl chloride resin and 30-80 parts by mass of cyclohexanedicarboxylic acid dialkyl ester (group of [Chemical Formula 1]). A second soft resin obtained by preparing a resin heat kneaded product and then additionally blending 1 to 30 parts by mass of chlorinated polyethylene with respect to 100 parts by mass of the vinyl chloride resin into the first soft vinyl chloride resin heat kneaded product Using a vinyl chloride resin heat kneaded product, a film roll-molded from the second soft vinyl chloride resin heat kneaded material is laminated on one or more surfaces of the fiber fabric, so that the film becomes a soft vinyl chloride resin layer, and the fiber fabric It is preferable to obtain a flexible laminate having the substrate as a base material. As a result, the plasticization of the soft vinyl chloride resin layer is made sufficiently and uniform, and the chlorinated polyethylene is post-dispersed in this, so that the entanglement constraint state of the chlorinated polyethylene molecular chain with respect to the plasticized soft vinyl chloride resin molecular chain can be reduced.
