一种钢管热轧用芯棒润滑剂
技术领域：
本发明涉及钢管加工技术领域，具体涉及一种钢管热轧用芯棒润滑剂。
背景技术：
芯棒是连轧管机组中最重要的热变形工具，通过轧辊与芯棒的共同作用，毛坯管被轧制成所要求的尺寸。芯棒的表面质量及润滑状态直接关系到产品的尺寸精度以及管体的内表面质量，因此芯棒润滑剂的选择十分关键。需要选择合适的润滑剂使金属变形均匀，降低轧制力和芯棒动力，减小钢管横截面壁厚不均，改善钢管内表面质量，降低芯棒表面温升，从而提高钢管热轧质量和芯棒的使用寿命。
发明内容：
本发明所要解决的技术问题在于提供一种润滑性优异、有利于提高钢管热轧质量和芯棒使用寿命的钢管热轧用芯棒润滑剂。
本发明所要解决的技术问题采用以下的技术方案来实现：

其制备方法包括如下步骤：
(1)向石蜡油和乳化硅油混合液中加入萜烯树脂和松香甘油酯，充分混合后于微波频率2450MHz、功率700W下微波处理10min，然后自然冷却至65-70℃保温混合30min，再加入氢化蓖麻油、抗氧增稠剂和双亲型纳米二氧化硅，混合均匀后继续微波处理10min，即得物料I；
(2)向水中加入菜籽饼和火山灰，并加热至回流状态保温处理30min，然后自然冷却至35-40℃，将所得混合物置于5-10℃下静置8h，再加入陶瓷微粉、蛭石粉和硬脂酸丁酯，充分混合后再次加热至回流状态保温处理10min，即得物料II；
(3)向物料I中加入物料II、月桂醇聚氧乙烯醚、聚乙烯吡咯烷酮和纳米碳纤维，搅拌形成均匀溶液，最后将混合物料加入球磨机中，球磨至细度小于50μm。
所述抗氧增稠剂由如下重量份数的原料制成：聚乙烯醇树脂8-11份、氢化松香5-8份、线性低密度聚乙烯3-6份、聚乙二醇6000 2-4份、柠檬酸三丁酯2-4份、壳聚糖季铵盐1-2份、聚合氯化铝1-2份、纳米钛白粉1-2份、磷酸三甲酚酯0.5-1份、钛酸酯偶联剂0.5-1份、氧化锆0.3-0.5份，其制备方法为：先将聚乙烯醇树脂、氢化松香和线性低密度聚乙烯加热至125-130℃保温混合10min，再加入柠檬酸三丁酯、纳米钛白粉和钛酸酯偶联剂，继续保温混合5min，然后在冰水浴下以10℃/min的速度降温，待温度降至15-20℃后加入聚乙二醇6000、壳聚糖季铵盐、聚合氯化铝、磷酸三甲酚酯和氧化锆，充分混合均匀后继续加热至75-80℃保温混合10min，即得抗氧增稠剂。
所述双亲型纳米二氧化硅的制备方法为：将20份硅酸钠、1份交联羧甲基纤维素钠和0.5份焦磷酸钠加入50份体积比1:1的乙醇与水混合溶剂中，充分分散后于微波频率2450MHz、功率700W下微波处理10min，再加入8份氯化铵、0.5份油酸聚氧乙烯酯和0.5份环氧大豆油，搅拌使其完全溶解后继续微波处理5min，处理结束后自然冷却至室温，然后将混合液置于0-5℃条件中静置12h，过滤，所得固体于100℃下烘干，最后于450-500℃下焙烧2h。
本发明的有益效果是：本发明所制润滑剂适用于钢管热轧芯棒，属于水溶性润滑剂，在40-50℃下即可完全溶解于水中，同时使用方便，使用时只需将其均匀喷涂于芯棒上即可，对芯棒无任何腐蚀作用；该润滑剂的润滑性能好且润滑用量少，不仅能够大大提高热轧加工后钢管的内表面质量，消除连轧后钢管两侧的横裂与人字裂口，降低报废率，解决了一般润滑剂不能轧制薄壁管的问题，同时有效延长芯棒的使用寿命。
