Description
技术领域
本发明涉及冷却液技术领域,尤其涉及一种用于蓝宝石切削加工工艺的冷却液。
背景技术
光学玻璃属于硬脆非金属材料,通常采用表面镶有金刚石的刀具、磨头进行玻璃制品的切削、磨削加工。切削、磨削加工时,因为工件或刀具、磨头的高速旋转会产生大量的热量,同时还会形成大量玻璃微粉。这种热量和玻璃微粉往往会对加工工具和工件产生各种不利影响。因此,必须在不影响切削质量和生产力的情况下,尽可能排除热量带走玻璃微粉。
通过喷射冷却液可以吸收热量并带走玻璃微粉,冷却液一般需要具备导热系数大、冷却、润滑和良好的沉降性。传统的冷却液大部分含有苯类衍生物、亚硝酸盐或添加大量的三乙醇胺,闪点比较低且易挥发,对操作工人身体有害,润滑冷却效果差,对玻璃粉末的沉降性差,导致加工不精准,不适合精磨加工。
蓝宝石晶体硬度大,强高度,在加工过程中更容易与刀具、磨头产生大量热量,因此蓝宝石加工对冷却液的要求较一般玻璃冷却液高。
发明内容
基于背景技术存在的问题,本发明提供了一种用于蓝宝石切削加工工艺的冷却液,该蓝宝石冷却液组分简单、环保,且具备良好的冷却性和润滑性。
本发明通过以下技术方案实施:
一种用于蓝宝石切削加工工艺的冷却液,按重量百分比包括以下组分:
进一步地,高分子聚醚混合物为聚乙二醇和丙二醇嵌段聚醚混合物,聚乙二醇和丙二醇嵌段聚醚的质量比为(4-6):1。
进一步地,聚乙二醇的分子量为1800-2200。
进一步地,丙二醇嵌段聚醚为丙二醇嵌段聚醚L-61,平均分子量为2000。
本发明种选用两种聚醚混合物作为冷却液的润滑剂,相较于单一的聚乙二醇,复配后的聚醚混合物运动粘度适中,且与水的互溶性较好,可以提高冷却液的稳定性和润湿能力。
进一步地,防锈剂为十二碳二元酸。
进一步地,沉降剂为阳离子聚季铵盐。
进一步地,偶联剂为钛酸酯偶联剂。
进一步地,消泡剂为聚丙二醇单丁醚。
进一步地,用于蓝宝石切削加工工艺的冷却液的制备方法,其特征在于,包括以下步骤:
(1)将高分子聚醚混合物加入搅拌反应釜中,加入去离子水,搅拌至混合均匀,加入防锈剂,水浴加热至60-80℃,继续搅拌至溶液透明,停止加热;
(2)向步骤(1)中溶液继续加入沉降剂和消泡剂,搅拌至混合均匀,加入偶联剂,继续搅拌混合均匀,即得蓝宝石冷却液。
进一步地,用于蓝宝石切削加工工艺的冷却液的使用方法,其特征在于,蓝宝石冷却使用前稀释1-20倍。
本发明的有益效果:
(1)本发明蓝宝石冷却液通过各组分之间的协同作用,提高了冷却液的结构稳定性。用于蓝宝石加工过程中,具有较好的水溶性,冷却效果好,润湿效果显著,能够减少加工过程中泡沫的沉淀,有效去除加工过程中产生的各种微小颗粒,提高了产品加工的精度。
(2)本发明蓝宝石冷却液不含磷、硫及有机碱,完全采用偶联剂搭配高分子、低溶点聚醚作极压,防锈剂不含亚硝酸盐和胺,不会对皮肤产生过敏问题。本发明蓝宝石冷却液成分简单,各组分协同作用,可完全溶于水,呈中性,绿色环保。

试验例一
蓝宝石冷却液性能测试
将实施例1-4和对比例1-4中的冷却液稀释20倍,根据GB/T 6144-2010,对冷却液的润滑性、消泡性、腐蚀性(55±2℃)和防锈性(35±2℃)进行测定,结果如表1所示。
表1
根据GB/T18712-2002对冷却液的沉降性进行测试,测试结果如下:
实施例1-4:上层澄清透明,玻璃粉2秒内全部沉降到底部;
对比例1:上层澄清透明,玻璃粉5秒内全部沉降到底部;
对比例2:上层轻微浑浊,玻璃粉5秒内不完全沉降到底部;
对比例3:上层轻微浑浊,玻璃粉30秒内不完全沉降到底部;
都比例4:上层轻微浑浊,玻璃粉30秒内不完全沉降到底部。
试验例二
将本发明实施例1-4和对比例1-4中的冷却液稀释20倍,用于蓝宝石加工,具体情况如下:
实施例1-4中冷却液用于金刚石切削蓝宝石时,连续切削10小时,去除相同量蓝宝石的切削时间无变化。
对比例1中冷却液用于金刚石切削蓝宝石时,连续切削10小时,去除相同量蓝宝石的切削时间需要延长10%以上。
对比例2中冷却液用于金刚石切削蓝宝石时,连续切削10小时,去除相同量蓝宝石的切削时间需要延长15%以上,且加工过程中产生的蓝宝石粉末悬浮在冷却液中,加工8小时后,冷却液呈轻微浑浊,并随着时间增长,溶液浑浊度加重,去除相同量蓝宝的切削时间液相应增加。
对比例3中冷却液用于金刚石切削蓝宝石时,连续切削10小时,去除相同量蓝宝石的切削时间需要延长20%以上,且加工过程中产生的蓝宝石粉末悬浮在冷却液中,加工6小时后,冷却液呈轻微浑浊,并随着时间增长,溶液浑浊度加重,去除相同量蓝宝的切削时间液相应增加。
对比例4中冷却液用于金刚石切削蓝宝石时,连续切削10小时,去除相同量蓝宝石的切削时间需要延长15%以上,且加工过程中产生的蓝宝石粉末悬浮在冷却液中,加工6小时后,冷却液呈轻微浑浊,并随着时间增长,溶液浑浊度加重,去除相同量蓝宝的切削时间液相应增加。
通过以上试验例的结果可以看出,本发明中的蓝宝石冷却液具有良好的润滑性、消泡性、腐蚀性和防锈性,用于蓝宝加工,冷却效果好,润湿效果显著,效去除加工过程中产生的各种微小颗粒,提高了产品加工的精度。
对比例1中采用单一聚乙二醇作为冷却液的润滑剂,冷却液的润湿性有所下降,相应润滑性也明显下降,同时,由于未添加丙二醇嵌段聚醚,冷却液的沉降性略受影响,用于蓝宝石加工对刀具、磨头产生不利影响。
对比例2和对比例3中调整了偶联剂用量,对比例2中降低了钛酸酯偶联剂用量,冷却液的稳定性变差,冷却液的润滑性降低,同时沉降性也降低趋势,用于蓝宝石加工对刀具、磨头产生不利影响。对比例3中增加了钛酸酯偶联剂用量,沉降性显著降低,用于蓝宝石加工对刀具、磨头产生不利影响。
对比例4中选用硅烷偶联剂,冷却液的润滑性和沉降性明显不如添加钛酸酯偶联剂的,用于蓝宝石加工对刀具、磨头产生不利影响。
最后应说明的是:以上所述实施例仅表达了本发明的几种实施方式,并不用以限制本发明创造,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,所作的任何修改、等同替换、改进等,均应包含在本发明创造的保护范围之内。因此,本发明专利的保护范围应以所附权利要求为准。
