Description

一种金属线材拉丝粉
技术领域
本发明属于拉丝粉技术领域，具体涉及一种金属线材拉丝粉。
背景技术
拉丝是一种金属加工工艺，在外力作用下使金属强行通过模具，金属截面积被压缩，获得符合尺寸和形状要求的技术加工方法。拉丝处理可使金属表面获得较强的金属质感，具有非常强的装饰效果。拉拔后的金属材料具有较好的防锈、耐磨损和外观亮丽等优点，既耐用又便于维护。
金属拉拔过程中，须使用润滑材料，其主要作用是减轻对拉拔金属和模具的摩擦损坏，延长模具使用寿命，保证产品的拉丝质量。现有的拉丝工艺多采用液态的润滑油作为拉丝介质，拉拔出的线材表面圆润、红腻、光滑、透亮，断丝率降低。但是润滑油耗量大、清洗费时费力、散热慢，并易损毁模具，影响产品质量，同时高温易引燃油品或使油品蒸发冒烟导致现场操作环境恶化。
此外，有的拉丝工艺采用固体粉末作为润滑剂，也称拉丝粉。目前市场上出现的拉丝粉的主要成分是石灰、动物油、石蜡、肥皂、滑石粉和碱等。实际生产中所使用的酸性拉丝成分会损坏材料的表面结构，降低材料表面的强度和韧性；石灰含有大量的杂志，后续加工过程中还需要进行筛选；石蜡中含有多环芳烃和稠环芳烃，这类致癌物质急难降解和消除，会对人体造成慢性伤害。
因此，开发生产出优质拉丝粉具有良好的市场前景和环保意义。
发明内容
本发明的目的是针对现有的问题，提供了一种金属线材拉丝粉。
本发明是通过以下技术方案实现的：
一种金属线材拉丝粉，按重量份计由以下成分制成：碳酸钠72-85、微硅粉10-12、硅藻泥5-8、硬脂酸钙12-15、柠檬酸钠3-15、滑石粉10-16、纤维素醚3-5、苯甲酸钠2-6、木质纤维素7-10、水15-20。
进一步的，所述微硅粉经过次氯酸钠溶液处理，具体为：将微硅粉添加到质量分数为5%的次氯酸钠溶液中，在39℃下浸泡30min，然后以1200r/min转速搅拌2小时，然后再自然冷却至室温，进行抽滤，采用去离子水对微硅粉进行表面清洗至中性，烘干至恒重，即得。
进一步的，所述烘干温度为350℃。
进一步的，所述滑石粉粒度为1250目。
进一步的，所述硅藻泥的孔隙率为95%，比表面积为68㎡/g。
本发明相比现有技术具有以下优点：本发明制备的拉丝粉具有良好的润滑性，微硅粉、纤维素醚和木质纤维素都具有良好的润滑性能，能在金属表面形成均匀致密的润滑膜，能有效降低拉拔金属和模具的摩擦损坏；具有良好的防腐性，柠檬酸钠能有效防止拉拔金属在酸性环境下的变形与变质；耐高温高压，微硅粉和硅藻泥具有阻燃和绝缘性良好等优点及耐热抗老化性能，高温高压条件下，能有效防止拉拔金属材料的烧结损伤和焦化变质；所用原料成本较低，无毒无污染，对操作人员无伤害，具有节能环保意义；化学性能稳定，在常温干燥环境中可长期保存；应用广泛，适用性强，可广泛应用于各种钢丝、铜丝和高档金属面板等材料的拉拔处理。
