Description

一种耐磨聚氨酯叉车轮
技术领域
本发明涉及聚氨酯技术领域，尤其涉及一种耐磨聚氨酯叉车轮。
背景技术
叉车轮是叉车的关键零部件之一，它的主要作用是承载重量和为叉车的转动提供精确引导，这就要求它不仅能承受轴向载荷还要承受径向载荷，所以要求其不仅具有较好的力学性能，还要有良好的耐磨性、耐热性和耐振动冲击性。目前叉车轮主要采用聚氨酯材料制备，但目前聚氨酯材料由于耐磨性能仍存在不足，成为制约叉车轮发展的短板。
发明内容
基于背景技术存在的技术问题，本发明提出了一种耐磨聚氨酯叉车轮，耐磨性能极好，拉伸强度与断裂伸长率高，而且原料易得，成本低廉，操作简单，同时有利于环保和降低生产成本，具有可观的经济效益和社会效益。
本发明提出的一种耐磨聚氨酯叉车轮，其原料按重量份包括：大分子多元醇20-30份，苯二亚甲基二异氰酸酯2-6份，1,6-六亚甲基二异氰酸酯2-4份，一缩二乙二醇0.5-1.5份，甘油1-2份，二月桂酸二丁基锡1-2份，烷基醇酰胺1-2份，硬脂酸镁2-6份，相容剂1-3份，抗氧剂1-2份，麦饭石复合物2-6份，云母粉1-5份，海泡石粉1-4份，玻璃纤维1-4份，纳米蒙脱土1-5份。
优选地，麦饭石复合物采用如下工艺制备：将麦饭石煅烧，冷却，粉碎，加入十二烷基苯磺酸钠、聚丙烯酰胺、无水乙醇搅拌均匀，洗涤，真空干燥得到麦饭石复合物。
优选地，麦饭石复合物的制备工艺中，煅烧时间为10-30min，煅烧温度为500-560℃。
优选地，麦饭石复合物的制备工艺中，真空干燥温度为95-105℃，真空干燥时间为4-6h。
优选地，麦饭石复合物的制备工艺中，麦饭石、十二烷基苯磺酸钠、聚丙烯酰胺、无水乙醇的重量比为20-30：1-2：5-15：80-100。
优选地，大分子多元醇按重量份包括：聚酯多元醇5-15份，聚醚多元醇10-20份。
优选地，抗氧剂按重量份包括：三(2，4-二叔丁基苯酚)亚磷酸酯1-2份，抗氧剂CA1-2份。
本发明采用聚酯多元醇、聚醚多元醇与苯二亚甲基二异氰酸酯、1,6-六亚甲基二异氰酸酯复配形成聚氨酯预聚体，不仅结合程度高，耐磨性能好，而且原料易得，成本低廉，操作简单，生产中无三废排放，有利于环保和降低生产成本，具有可观的经济效益和社会效益，再与麦饭石复合物配合作用，可有效增强聚氨酯的耐磨性能，而且增韧效果极好。
本发明的麦饭石复合物中，麦饭石经过高温煅烧后，内部形成大量活性空洞，在十二烷基苯磺酸钠的配合下与阴离子聚丙烯酰胺牢固接枝，形成吸附网状结构，可与云母粉、海泡石粉、玻璃纤维、纳米蒙脱土进行吸附容纳，不仅具有良好的相容性、抗冲击性、增韧性，而且耐磨性能极好，拉伸强度与断裂伸长率高。
