Description
技术领域
本申请涉及清除液的领域,尤其是涉及一种用于手机塑胶边框去毛刺的清除液及其清除方法。
背景技术
手机塑胶边框注塑成型后需要进行后续加工,在后续加工的过程中需要喷涂油漆,若塑胶边框上存在毛刺,会导致最终产品出现鼓包等外观问题,因此在喷涂油漆前需要去除塑胶边框上的毛刺。
目前去除毛刺的方法主要是人工去除,工人用百洁布对手机塑胶边框进行反复擦拭,但是这种去除方式去除效率低,且容易使得塑胶边框表面出现划伤。
发明内容
为了提高塑胶边框上毛刺的去除效率且不划伤塑胶边框的表面,本申请提供一种用于手机塑胶边框去毛刺的清除液及其清除方法。
第一方面,本申请提供的一种用于手机塑胶边框去毛刺的清除液,采用如下的技术方案:
一种用于手机塑胶边框去毛刺的清除液,包括研磨颗粒和原液,所述原液包括如下重量份的组分:溶剂介质70~90份、分散剂1~5份、渗透剂1~10份和增稠剂0.5~5份。
通过采用上述技术方案,分散剂使得研磨颗粒均匀分散在原液中,在超声空化作用下,研磨颗粒反复碰撞和摩擦塑胶边框上的毛刺,从而将毛刺软化和削平,完成毛刺的去除,无需人工进行操作,提高了毛刺的去除效率;通过增稠剂和渗透剂的配合,使得研磨颗粒的摩擦运动脱离于塑胶边框的表面,从而减少了研磨颗粒对塑胶边框的划伤。
在一个具体的可实施方案中,所述研磨颗粒与所述原液的重量比为1:(3~10)。
通过采用上述技术方案,当清除液中的研磨颗粒较少时,对塑胶边框上的毛刺清除不充分;当清除液中的研磨颗粒较多时,会对塑胶边框的表面造成划伤;本申请中进一步优化清除液中研磨颗粒和原液的配比,使得清除液既可以充分清除塑胶边框上的毛刺,又不会对塑胶边框的表面造成划伤。
在一个具体的可实施方案中,所述研磨颗粒为碳酸氢钠磨料。
通过采用上述技术方案,碳酸氢钠磨料的脆性较大,在撞击时会破裂,晶体碎片会沿着塑胶边框分散,因此减小了对塑胶边框的划伤;且碳酸氢钠磨料溶于水、无毒,在清理完毕后不会产生废料,提高了清除液的环保性。
在一个具体的可实施方案中,所述分散剂为聚丙烯酸钠和乙二醇的混合物,且聚丙烯酸钠和乙二醇的重量比为1:(1~2)。
通过采用上述技术方案,聚丙烯酸钠具有较好的分散作用,但是聚丙烯酸钠不易溶于有机溶剂,乙二醇使得聚丙烯酸钠溶解在清除液中;并且聚丙烯酸钠还具有较高的粘性,从而减小了增稠剂的使用量;本申请中进一步优化了聚丙烯酸钠和乙二醇配比,提高了毛刺的去除效果。
在一个具体的可实施方案中,所述增稠剂为三羟甲基丙烷油酸酯和油酸的混合物,且三羟甲基丙烷油酸酯和油酸的重量比为1:(0.8~1.2)。
通过采用上述技术方案,三羟甲基丙烷油酸酯和油酸在提高清除液粘度的同时,两个相互配合,还能提高手机塑胶边框的清洁度;且本申请中进一步优化三羟甲基丙烷油酸酯和油酸的配比,使得手机塑胶边框的清洁效果更好。
在一个具体的可实施方案中,所述原液还包括1~5重量份的活性剂,且所述活性剂为脂肪醇聚氧乙烯醚。
通过采用上述技术方案,脂肪醇聚氧乙烯醚既具有一定的渗透作用,又具有一定的洗涤效果,提高了手机塑胶边框的清洁度。
第二方面,本申请还提供一种用于手机塑胶边框去毛刺的清除方法,采用如下的技术方案:
一种用于手机塑胶边框去毛刺的清除方法,包括以下步骤:
清除:先将分散剂、渗透剂、增稠剂和活性剂依次加入溶剂介质中,搅拌均匀,得到原液,再将研磨颗粒加入到原液中,搅拌均匀,制得清除液,然后将清除液加入到超声波设备中,最后放入待去毛刺的手机塑胶边框进行清除;
清洗:利用纯水对清除完毛刺的塑胶边框进行喷淋清洗;
漂洗;向超声波设备中加入纯水,对喷淋清洗完的塑胶边框进行超声漂洗;
烘干;将超声清洗完的塑胶边框烘干。
通过采用上述技术方案,将清除液加入超声波设备中,然后将手机塑胶边框放入清除液中,在超声波的空化作用下,研磨颗粒反复碰撞和摩擦塑胶边框上的毛刺,将毛刺削平,从而去除毛刺;再将清除完毕的塑胶边框清洗,烘干。
在一个具体的可实施方案中,所述清除步骤中,清除时间为5~15min。
通过采用上述技术方案,当清除时间小于5min时,手机塑胶边框上的毛刺清除不充分;当清除时间大于15min时,当手机塑胶边框上的毛刺清除完毕后,研磨颗粒会对塑胶边框的表面造成划伤;本申请中清除时间为5~15min,使得塑胶边框上的毛刺去除充分,又不会对塑胶边框上的表面造成划伤。
在一个具体的可实施方案中,所述清除步骤中,清除温度为30~50℃。
综上所述,本申请包括以下至少一种有益技术效果:
1.本申请中分散剂使得研磨颗粒均匀分散在原液中,在超声空化作用下,研磨颗粒反复碰撞和摩擦塑胶边框上的毛刺,从而将毛刺软化和削平,完成对毛刺的去除,无需人工进行操作,提高了毛刺的去除效率;通过增稠剂和渗透剂的配合,使得研磨颗粒的摩擦运动脱离于塑胶边框的表面,从而减少了研磨颗粒对塑胶边框的划伤;
2.本申请中碳酸氢钠磨料的脆性较大,在撞击时会破裂,晶体碎片会沿着塑胶边框分散,因此减小了对塑胶边框的划伤;且碳酸氢钠磨料溶于水、无毒,在清理完毕后不会产生废料,提高了清除液的环保性;
3.本申请中的方法,利用清除液对手机塑胶边框清除5~15min,使得塑胶边框上的毛刺去除充分,又不会对塑胶边框上的表面造成划伤。

结合应用例1、对比应用例1和对比应用例2,对比应用例1和对比应用例2中塑胶边框上有划伤,可见在清除塑胶边框上的毛刺时,清除液中的增稠剂和渗透剂使得研磨颗粒的摩擦运动脱离于塑胶边框的表面,从而减小了耐磨颗粒对塑胶边框表面的划伤。
结合应用例1和应用例2,应用例2中的塑胶边框上的污垢较少,可见在制备清除液时,向清除液中加入脂肪醇聚氧乙烯醚,脂肪醇聚氧乙烯醚具有一定的洗涤效果,从而提高了手机塑胶边框的清洁度。
结合应用例2~4,实施例2~4中塑胶边框均为2级毛刺、无划伤,且污垢较少,可见在制备清除液时,提高原液原料的使用量,对清除液的清除效果影响不大。
结合应用例3和应用例5~8,应用例5~7中塑胶边框的毛刺和污垢均较少,且无划伤,可见当研磨颗粒与原液的重量比为1:(3~10)时,制得清除液的清除效果较好,且对塑胶边框的表面无划伤;应用例8中的塑胶边框上有划伤,可见当清除液中研磨颗粒含量较多时,会对塑胶边框的表面造成划伤。
结合应用例6和应用例9~12,应用例9~11中塑胶边框的无毛刺,且污垢较少,可见当聚丙烯酸钠和乙二醇的重量比为1:(1~2)时,制得清除液的清除效果较好,且对塑胶边框的表面无划伤。
结合应用例10和应用例13~16,应用例13~15中的塑胶边框无污垢,可见当三羟甲基丙烷油酸酯和油酸的重量比为1:(0.8~1.2)时,制得清除液的去污效果较好,从而提高了塑胶边框的清洁度。
结合应用例14和应用例17~20,应用例17中的塑胶边框上有毛刺,可见当清除时间较少时,清除液对塑胶边框上的毛刺清除不充分;应用例20中塑胶边框的表面上有划伤,可见当清除时间较长时,塑胶边框上无毛刺,研磨颗粒会对塑胶边框造成划伤;应用例14、应用例18和应用例19中塑胶边框上无毛刺且无划伤,可见当清除时间为5~15min时,清除完的塑胶边框无毛刺且无划伤。
结合应用例14和应用例21~24,应用例14和应用例21~24中塑胶边框上均无毛刺、无划伤、无污垢,可见在去毛刺时,清除温度对清除液的清除效果影响不大。
