Description

高抗压印染胶辊
技术领域
本发明属于高分子材料技术领域，具体涉及高抗压印染胶辊。
背景技术
随着装备制造业和高分子材料的发展，印染设备及关键配件也在逐步升级换代，同时人们对于各种印染产品的质量也提出了更高的要求，印染胶辊作为印染设备的关键配件，直接与印染产品接触，其质量可靠性直接影响到印染产品的质量。
现有的印染胶辊，其表面抗压70000N～80000N(牛顿)，由于胶辊表面压力较大，印染胶辊在使用不久后，出现不同程度的变形、脱胶等问题。
发明内容
本发明的目的是提供一种高抗压印染胶辊，解决了现有技术中存在的印染胶辊抗压能力小导致的变形、脱胶的问题。
本发明所采用的技术方案是，高抗压印染胶辊，包括辊芯，辊芯外部从内到外依次包覆有底胶层、内骨架层、中胶层Ⅰ、骨架层Ⅰ、中胶层Ⅱ、骨架层Ⅱ和外层，辊芯表面为双螺纹线结构，表面经喷砂处理，内骨架层、骨架层Ⅰ、骨架层Ⅱ均采用聚酯线绳交叉编织而成，聚酯线绳单根强度≥1900N/根，层间呈45°交叉。
本发明的特点还在于，
底胶层为橡胶材料层，硬度为92±2邵尔A，拉伸强度≥15MPa，拉断伸长率≥100％，永久变形≤10％，撕裂强度≥50kN/m。
中胶层Ⅰ、中胶层Ⅱ、外层均为橡胶材料层，硬度为82±2邵尔A，拉伸强度≥12MPa，拉断伸长率≥120％，永久变形≤10％，撕裂强度≥45kN/m。
本发明的有益效果是，高抗压印染胶辊，采用橡胶与骨架线绳复合结构，骨架层赋予胶辊整体一定的形变，以增加辊芯与覆层材料的包裹性，缓冲或抵消胶辊外表所受的挤压力。
