- a PFA resin film is laminated on a high-strength reinforcing layer material that is thermally compressed before being laminated as a belt. This provides wear resistance and a low friction surface, which can significantly improve belt life.
- Example 5 an aramid fiber bag woven (seamless) woven fabric with yarn specifications shown in Table 3 below was impregnated with PFA dispersion, dried, and fired to produce a core having a thickness of 0.8 mm.
- the mass of the core was 1420 g / m 2 .
- weft yarn (yarn in the circumferential direction of the belt) was woven in Z twist and S twist alternately for each wood pipe.
- a reinforcing layer 23 having a thickness of 1.3 mm is formed on the core through a PFA film (adhesive layer) 22 having a thickness of 200 to 250 ⁇ m.
- the reinforcing layer 23 was obtained by impregnating an aramid fiber knit knitted fabric with a PTFE dispersion, drying, sintering by firing, and repeating this process several times.
- the belt of Example 4 has a smaller dynamic friction coefficient on the surface after 50 grindings than that of Example 5. For this reason, even when a core paper with poor paper quality is used, the core paper can smoothly move on the belt. Although the peripheral speed of the belt differs between the center and the end in the belt width direction, according to the fourth embodiment, the core paper smoothly moves on the belt, so that the liner paper from the core paper due to variations in the peripheral speed. Can be prevented.
- Examples 1, 2, 3, and 4 which are belts of the present invention have a significantly longer service life as heat-resistant laminated conveyor belts used in corrugated paper manufacturing apparatuses than the belts shown in Example 5. It has been demonstrated that it can be extended.
- the core used in the examples had a thickness of 1.0 to 1.3 mm and a mass of 1500 g / m 2.
- the core is not limited to these values as long as sufficient core strength is obtained. Absent. For example, even if the mass of the core used in Example 2 is changed to 1650 g / m 2 , the same effect can be obtained.
- the thickness of the core is preferably 1 mm or more and 3 mm or less, and the mass of the core is preferably 1500 g / m 2 or more and 3000 g / m 2 or less.
- an aramid fiber knit knitted fabric was used as the aramid fiber woven fabric imparted with stretchability, but it is not particularly limited as long as it is a stretchable aramid fiber woven fabric.
- an aramid fiber woven fabric made by sword knitting, warp knitting (for example, denby knitting, cord knitting, atlas knitting, etc.), weft knitting (for example, flat knitting, rubber knitting, pearl knitting, etc.) Since it has, it can be used.
- Example 1 one S-twisted weft and one Z-twisted weft were alternately arranged, and the spacing between the S-twisted weft and the Z-twisted weft was about 25 mm. It is not limited. An S-twisted weft and a Z-twisted weft may be arranged in the width direction of the belt, that is, the warp. For example, two S-twisted weft yarns and two Z-twisted weft yarns can be alternately arranged (S, S, Z, Z). In this case, the switching between the S-twisted weft and the Z-twisted weft is performed at intervals of about 50 mm.
- Example 2 Also in Example 2, one S-twisted weft and one Z-twisted weft were alternately arranged, but the present invention is not limited to this arrangement.
- the cylindrical loom used in Example 2 can weave yarns in a spiral shape by rotating, for example, 3 to 4 shuttles simultaneously. For this reason, it is possible to weave a certain number of weft yarns alternately by changing the twist direction of the yarn set in the shuttle to S twist or Z twist. Therefore, it is easy to change the arrangement of the threads as compared with the shuttle loom used in Example 1.
- the stress applied to the belt can be relieved, so the running performance of the belt can be improved.
- the number of the S-twisted weft and the number of the Z-twisted weft are the same so that the S and Z are switched at equal intervals. It is desirable.
- the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
- various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.

Abstract
Description
図中の符番1は、主としてベルトの機械的強度を担う補強層である。この補強層1上には、四フッ化エチレンパーフロロアルキルビニルエーテル共重合体樹脂(PFA樹脂)フィルムからなる接着層2を介して耐摩耗層3が形成されている。ここで、耐摩耗層3は、ベルトに耐摩耗性、離型性、硬度等を付与することにより良好な貼合わせ特性を提供する機能を有する。
更に、芯体、接着剤層及び表面織布層という三層構成のコンベアベルトも提案されている(例えば特許文献3)。
図中の符番11は、下段ロール12と噛合する上段ロールを示す。前記上段ロール11の上側には、該上段ロール12に近接して2つの圧力ロール13a,13bが配置されている。これらの圧力ロール13a,13bには、無端状の加圧ベルト14が跨設されている。
実施形態に係る耐熱性積層コンベアベルトは、例えば、前記芯体、補強層用材料を個別に作製し、接着層として用いられるフッ素樹脂フィルムを介して積層成形される。
この際、接着層として用いられるフッ素樹脂フィルムは、限定するものではないが、例えば、溶融可能なフッ素樹脂フィルムとして最高の耐熱性を有する四フッ化エチレンパーフルオロアルキルビニルエーテル共重合樹脂(PFA樹脂)フィルム、四フッ化エチレン-六フッ化プロピレン共重合樹脂(FEP樹脂)フィルム、変性ポリテトラフルオロエチレン樹脂(変性PTFE樹脂)フィルムが好適に使用される。
しかしながら、それにも限界があり、本発明においては、積層ベルトとして芯体と補強層材料の積層を行なう前に、アラミド繊維からなる伸縮性を付与した織布にフッ素樹脂ディスパージョンを含浸、乾燥、焼成してなる補強層用材料を熱圧縮し、その後、積層することによって硬度を上げることが可能であることを見出した。
本発明においては、ベルトとして積層する前に熱圧縮された硬度の高い補強層用材料上にPFA樹脂フィルムを積層し、耐摩耗性及び低摩擦表面を付与することでよりベルト寿命が著しく改善されることを見出した。ここで、PFA樹脂フィルムの厚さとしては、50μm~1000μm程度が好適に使用可能である。
