Description

一种聚氨酯抛磨轮及其制备方法
技术领域
本发明涉及一种抛磨轮及抛磨轮的制备方法，特别是指一种聚氨酯抛磨轮及其制备方法。
背景技术
近年来聚氨酯制备抛光研磨耗材国内外都应用比较多，聚氨酯材质制作的抛磨产品具有弹韧性好，切削效率理想，相比其他环氧树脂、聚酰胺树脂、聚酯树脂、酚醛树脂制作的抛磨轮产品要耐用。
目前采用聚氨酯材料制作抛磨轮产品主要有两种形式:
1、发泡料制作的发泡研磨抛光轮，加入溶剂、磨料、催化剂、发泡剂、匀泡剂、散热剂等，产品具有发泡微孔，产品弹韧性好，打磨的光洁度好
2、是用聚氨酯弹性体材料，加入溶剂、磨料、填料、抗氧化剂等，用以浸渍尼龙不织布纤维后，层压固定成型后冲压固化成最终产品，此种抛光轮产品具有弹性好，打磨时贴合工件，抛磨的镜面效果好，对金属，合金，玻璃，陶瓷，木材等都有较好的抛磨效果。
采用聚氨酯发泡形式制作的抛光轮产品，由于发泡时间和与生产操作时间不易控制，且起泡凝胶时间难平衡，导致浸渍纤维增强难以实现，容易受环境温度和湿度的影响，生产结构不均匀，使生产的产品强度不足，容易产生爆裂。而采用聚氨酯弹性体形式制作的抛光轮产品，虽添加了尼龙纤维进行固定增强产品结构强度，但聚氨酯树脂胶料缺乏发泡结构，抛光轮产品打磨抛光金属等材料时，容易使产品和抛磨工件发热，引起树脂碳化在工件表面残留，影响使用和打磨工件的效果。
此外，生产制备中，单纯的聚氨酯发泡轮无纤维增强，易造成结构不均一，导致强度不足，且需要模具加热加压固化定型，而无纺布抛光轮制作生产周期长，聚氨酯发泡胶不适应，难以制作多层数的产品。
发明内容
本发明的目的在于克服现有技术中的问题，提出一种既可以增强产品结构，又能使产品具有发泡结构，从而实现在产品强度和抛磨效果都理想的抛磨轮。
为解决上述技术问题，本发明采用以下技术方案予以实现：
一种聚氨酯抛磨轮，其包括若干层涂覆有耐磨浆料的尼龙纤维无纺布，所述的耐磨浆料包括如下重量份的组分：
封端型聚氨酯预聚体100份，扩链剂10-40份，溶剂5-15份，发泡剂0.01-0.5份，催化剂0.01-0.5份，抗氧化剂0.1-0.8份，磨料100-500份，润滑剂2-20份，色粉0.5-5份。
进一步地，所述的封端型聚氨酯预聚体为聚醚型封端聚氨酯预聚体、聚酯型封端聚氨酯预聚体中的一种或两种。
合成聚氨酯预聚体的主要材料为两种：一种是聚合多元醇类，包括聚醚多元醇和聚酯多元醇，聚醚多元醇又可以包括很多类，比如聚氧化丙烯醚二元醇，聚四氢呋喃醚二醇等；聚酯多元醇又有聚碳酸酯二元醇、聚己内酯二元醇等。另一种材料是多异氰酸酯，包括甲苯二异氰酸酯TDI型、二甲苯甲烷二异氰酸酯MDI型、萘二异氰酸酯NDI型、六次甲基二异氰酸酯HDI型、对苯基二异氰酸酯PPDI型等。
进一步地，所述的扩链剂选自1，4-丁二醇、乙二醇、一缩二乙二醇、1，6-己二醇、HQEE、甘油、季戊四醇、3，3-二氯-4，41-二苯基甲烷二胺、4，41-二氨基二苯基甲烷、甲苯二胺、3，5-二甲硫基甲苯二胺、3，5-二乙基甲苯二胺、三乙醇胺、二乙醇胺、三异丙醇胺、甲基二乙醇胺、己二酸、对苯二甲酸、间苯二甲酸中的一种或多种。
进一步地，所述的溶剂选自醋酸乙酯、醋酸丁酯、丙酮、甲乙酮、甲苯、二甲苯、二甲基甲酰胺、丙二醇单甲醚醋酸酯中的一种或多种。
进一步地，所述的发泡剂选自水、二氯氟乙烷、环戊烷、戊烷、五氟丙烷、液体二氧化碳、二氯甲烷、1,1-二氟乙烷中的一种或多种。
进一步地，所述的催化剂选自三亚乙基二胺、二甲基环己胺、N-甲基二环己胺、五甲基二亚乙基三胺、四甲基乙二胺、四甲基丙二胺、四甲基己二胺、2,4,6-三(二甲氨基甲基)苯酚、二甲基乙醇胺、三甲基乙氧基丙二胺、三甲基羟乙基乙二胺、N-甲基吗啉、N-乙基吗啉、N-甲基咪唑、DBU、三乙胺、二月桂酸二丁基锡、辛酸亚锡、异辛酸钾、醋酸钾、油酸钾、醋酸苯汞、钛酸四丁酯、钛酸四异丙酯中的一种或多种。
进一步地，所述的抗氧化剂选自抗氧剂245、抗氧剂264(BHT)、抗氧剂1010、抗氧剂1035、抗氧剂3114、亚磷酸三苯基酯、亚磷酸二苯基异辛酯、抗氧剂B215、抗氧剂B225中的一种或多种。
进一步地，所述的磨料选自黑碳化硅、绿碳化硅、白刚玉、棕刚玉、黑刚玉、单晶刚玉、锆刚玉、金刚石、氮化硼中的一种或多种，且磨料粒度范围不小于60#。
进一步地，所述的润滑剂选自滑石粉、高岭土、碳酸钙、硬脂酸锌、硬脂酸钡、硬脂酸钙、硬脂酸铅、硬脂酸锂、聚乙烯蜡粉、聚四氟乙烯蜡粉、聚酰胺蜡粉中的一种或多种，润滑剂粒径小于10um。
进一步地，所述的色粉选自铁红粉、耐温红粉、炭黑、钛白粉、铬绿粉、橙黄粉中的一种或多种。
上述的聚氨酯抛磨轮的制备方法，包括如下步骤：
S1、计量好所需的组分及含量，依溶剂、封端型聚氨酯预聚体、抗氧化剂、催化剂、扩链剂、发泡剂的加料顺序，在1000-2000r/min的转速下室温搅拌加料，完成加料后继续室温搅拌3-10min，然后在1500-3000r/min转速下依次加入色粉、润滑剂、磨料，并在室温搅拌3-10min得到耐磨浆料；
S2、把搅拌好的耐磨浆料输送到涂覆机的两滚轴上，以200-900r/min的转速辊压在两滚轴间的尼龙纤维无纺布上，把带有耐磨浆砂的无纺布裁剪成所需产品规格的形状，叠压成具有不同层数和厚度的布块，然后用布块锁紧定型模板将布块固定成型；
S3、用翻转机械翻转1-8小时后进行脱模，得到半成品的布块，将布块晾置3-12小时后用冲床冲压成各种规格的抛磨轮半成品，抛磨轮半成品在热风烘炉中60-180摄氏度烘烤硫化2-20小时，自然降温到室温后出炉得到聚氨酯抛磨轮成品。
本发明与现有技术相比具有的有益效果为：
本发明的聚氨酯抛磨轮，与市场同类型的抛磨轮相比，在耐用程度上提升1倍左右，表面粗糙度值减小约50％。
本发明依据聚氨酯原材料的配比配方调制出弹韧性、耐磨性的胶黏剂，通过发泡剂的原理使胶黏剂产生均匀的发泡机构，有利于工件抛磨时吸收和排除磨屑，有利于散热，加入的润滑剂也是起到抛磨时的散热作用避免工件生产高温烧伤，尼龙纤维主要起到对产品结构的增强的作用。基本原理就是依据聚氨酯材料的弹韧性、耐磨性及对工件的贴合性，通过发泡、散热、纤维增强等原理和工艺进行制作产品达到客户抛磨要求的新产品。

各配方实施例产品质检性能对比：
采用砂轮磨耗比测试仪测定聚氨酯抛磨轮的耐磨度，用粗糙度仪测试抛磨后工件表面的粗糙度。抛磨轮试样产品尺寸直径203mm，厚度50mm，孔径20mm，测试模块为硬质合金，测试转速2800r/min，测试时间为5分钟，测试恒定压力为500克。
序号 实施例1 实施例2 实施例3 市场同类产品
粗糙度Ra(um) 0.615 0.802 1.116 1.528
耐磨度g/min 25.5 22.6 20.2 53.8
粗糙度值越小，说明表面效果越好，越平整。耐磨度数值越小，说明再一定时间和压力下，抛磨轮的消耗量越小，说明轮子越耐磨耐用，反之，越大说明消耗越快，越不耐磨耐用。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
