Description
技术领域
本发明涉及金属表面处理技术领域，具体涉及一种用于铝材拉伸的成膜剂。
背景技术
铝管材的应用越来越广泛，铝管材制作成为至关重要，传统铝管制作通常采用一个粗坯铝管，再进行精细加工，如抽管加工，主要是通过将铝管坯料抽拉，进行冷拔加工，以达到直径大的管抽变成小直径的管材。
铝抽管时通常需要采用润滑剂等加工助剂进行处理，否则抽拉管时容易出现裂纹、拉管不均匀等不良现象。现有的铝抽管预处理工艺是：直接洒滑石粉或涂抹润滑油等到工件上进行润滑就进行拉伸，其缺点是润滑效果不理想，拉伸时工件各部位受力不均匀，只能进行一两次的拉伸，拉伸长度不超过20％，并且容易断裂。
对发明的公开
技术问题
有鉴于此，提供一种耐拉伸、拉伸率高和效果好的用于铝材拉伸的成膜剂。
问题的解决方案
技术解决方案
一种用于铝材拉伸的成膜剂，用于抽拉铝材前的预处理，其包括按照质量百分配比的下列成分：1-3％的氟硅酸钠，0.1-0.3％的氟化锌，0.05-0.10％的氟化钠和余量水。
发明的有益效果
有益效果
上述用于铝材拉伸的成膜剂采用锌系成膜剂处理铝材表面，形成皮膜，这样使待拉管件更易于抽拉，拉伸次数可达6-8次，拉伸长度超过80％，拉伸率高，拉伸后的铝管表面光亮，无裂纹，效果优良。
发明实施例
本发明的实施方式
以下将结合具体实施例对本发明进行详细说明。
本发明实施例提供一种用于铝材拉伸的成膜剂，用于铝材拉伸的成膜剂，用于抽拉铝材前的预处理，其包括按照质量百分配比的下列成分：1-3％的氟硅酸钠，0.1-0.3％的氟化锌，0.05-0.10％的氟化钠和余量水。上述成膜剂主要适用于铝管的拉伸预处理。
优选地，所述氟硅酸钠的质量百分含量为1.5-1.8％。所述氟化锌的质量百分含量优选为0.15-0.18％。所述氟化钠的质量百分含量优选为0.05-0.08％。所述成膜剂的总酸度优选为20-55pt。更优选地，成膜剂包括按照质量百分配比的下列成分：1.7％的氟硅酸钠，0.17％的氟化锌，0.07％的氟化钠和余量水。以上成分可称为主成膜剂，另外，成膜剂还包括皂化组，所述皂化组以辅助试剂形式单独配制，使用时，先用主成膜剂浸泡铝材，然后再将铝材浸泡于皂化组试剂中，皂化组包括质量百分含量为6-8％的硬脂酸锌水溶液和/或质量百分含量为2-4％的硬脂酸钠水溶液。所述成膜剂形成的膜厚优选为3-10微米。所述锌系成膜剂形成的皮膜主要起润滑作用，添加硬脂酸盐后，更能提高抽拉时的润滑效果。其中，氟化锌是主要成膜成分，氟硅酸钠和氟化钠是促进剂最后膜的成分为锌系膜。
实际应用中，成膜过程：用锌系成膜剂在80-100℃温度下处理铝材表面2-4分钟。皮膜是通过浸泡方式形成，浸泡的锌系成膜剂总酸度控制在20-55pt范围内，形成皮膜后，再在PH值为8-11，60-80℃温度下用6-8％质量浓度的硬脂酸锌水溶液和/或2-4％质量浓度的硬脂酸钠浸泡2-5分钟，这样在铝管表面形成皮膜，提高铝材拉伸时的润滑性和牢固性，可保证多次拉伸抽管而不断裂。
以下通过具体实例说明本发明实施例的用于铝材拉伸的成膜剂及其在铝抽管测试试验。
实施例1～3和对比例4～6
1)预处理：将待处理的铝管坯料用浓度为7％的片碱液除油和毛刺，用工业自来水清洗1-2次。
2)将前步骤处理后的铝管浸泡于浓度为8-10％的硝酸溶液中，在常温下，浸泡1分钟，用工业自来水清洗1-2次，彻底去除铝管表面黑灰。
3)按照表1的质量配比配制锌系成膜剂，用该锌系成膜剂在80℃温度下浸泡铝材4分钟，锌系成膜剂的酸度为20pt，再水洗，干燥。
4)按照表1的配比加入皂化组，即硬脂酸锌水溶液和/或硬脂酸钠水溶液，控制PH值为8，将经过步骤3)处理后的铝管继续在80℃温度下浸泡4分钟，最后处理得到的铝管再做拉伸测试，结果如表1所示。由表1的测试结果可知，实施例1-3采用了锌系成膜剂和皂化剂，铝管拉伸的延伸率超过80％，而对比例4没有采用锌系成膜剂，铝管拉伸的延伸率较低，而对比例5-6虽然采用锌系成膜剂，但是各成分含量较高，过高的含量还会溶解原来形成的膜，因此不利于成膜，导致锌系成膜剂实际上没有发挥应用的作用。
表1 各实施例中的各成分配比和测试结果
[Table 1]
需要说明的是，本发明并不局限于上述实施方式，根据本发明的创造精神，本领域技术人员还可以做出其他变化，这些依据本发明的创造精神所做的变化，都应包含在本发明所要求保护的范围之内。
