一种钛及钛合金热挤压用玻璃防护润滑剂及其制备方法
摘要：
本发明属于钛及钛合金型材制备领域，公开了一种钛及钛合金热挤压用玻璃防护润滑剂及其制备方法。该玻璃防护润滑剂包括玻璃微珠、石墨、二硫化钼和粘接剂；玻璃微珠、石墨和二硫化钼的质量比为30～90：5～40：5～30。其中，玻璃微珠按质量份数计包括：氧化钡或碳酸钡3～8份、二氧化硅30～45份、氧化钙或碳酸钙5～10份、氧化钠20～30份、硼砂10～25份、氧化镁3～5份、氧化铝1～5份。本发明润滑剂化学稳定性良好，与钛及钛合金材料不起化学反应，与钛及钛合金材料的润湿性良好，润滑性能好，可广泛用于钛及钛合金热挤压成型的应用领域。
摘要（英）：

The invention belongs to the field of preparation of titanium and titanium alloy proximate matters, and discloses a glass protecting lubricant for hot extrusion of titanium and titanium alloy and a preparation method thereof. The glass protecting lubricant comprises glass microbeads, graphite, molybdenum disulfide and an adhesive, wherein the mass ratio of the glass microbeads, the graphite and the molybdenum disulfide is (30-90):(5-40):(5-30); the glass microbeads comprise the following components in parts by mass: 3-8 parts of barium oxide or barium carbonate, 30-45 parts of silicon dioxide,5-10 parts of calcium oxide or calcium carbonate, 20-30 parts of sodium oxide, 10-25 parts of borax, 3-5 parts of magnesium oxide and 1-5 parts of aluminum oxide. The lubricant is good in chemical stability, free of a chemical reaction with titanium and titanium alloy materials, good in wettability with the titanium and titanium alloy materials and good in lubricating performance, and can be widely applied to the application field of the hot extrusion of the titanium and the titanium alloy.
