Mixed casting nylon sleeper
The invention discloses a mixed casting nylon sleeper which is formed by mixing and casting a main material and an auxiliary material in percentage by mass, the main material is caprolactam, and the auxiliary material is sodium hydroxide, toluene diisocynate, glass fiber powder, glass beads, peregal, polyethylene glycol, a PVT liquid flexibilizer, sodium carbonate, silicone grease or silicone oil, toner and molybdenum disulfide. The main material is caprolactam, and the auxiliary material is sodium hydroxide, toluene diisocynate, glass fiber powder, glass beads, peregal, polyethylene glycol, PVT liquid flexibilizer, sodium carbonate, silicone grease or silicone oil, toner and molybdenum disulfide. The composite material is prepared from the following raw materials in percentage by mass: 0.1 to 0.15 percent of sodium hydroxide, 0.8 to 1.2 percent of toluene diisocynate, 6 to 8 percent of glass fiber powder, 4 to 6 percent of glass beads, 2 to 3 percent of peregal, 2 to 3 percent of polyethylene glycol, 3 to 4 percent of PVT (Polyvinyl Pyrrolidone) liquid flexibilizer, 2 to 3 percent of sodium carbonate, 1 to 2 percent of silicone grease or silicone oil, 0.5 to 1 percent of toner, 2 to 3 percent of molybdenum disulfide and 65.65 to 76.6 percent of caprolactam. The product provided by the invention has excellent mechanical properties, bending strength and shear strength, low water absorption, high and low temperature climate resistance, corrosion resistance and good insulativity; the device is simple in structure, reduces vibration and noise, reduces secondary airborne sound, improves driving comfort and track safety, protects the service life of a track bed, and greatly reduces maintenance cost and workload of railway infrastructures.
本发明公开了一种混铸尼龙轨枕，它由主料和辅料依质量百分比混铸而成，主料为己内酰胺，辅料有：氢氧化钠，甲苯二乙氰酸酯，玻璃纤维粉，玻璃微珠，平平加，聚乙二醇，PVT液态增韧剂，石钠，硅脂或硅油，色粉，二硫化钼；各原料质量百分比如下：氢氧化钠0.1‑0.15%，甲苯二乙氰酸酯0.8‑1.2%，玻璃纤维粉6‑8%，玻璃微珠4‑6%，平平加2‑3%，聚乙二醇2‑3%，PVT液态增韧剂3‑4%，石钠2‑3%，硅脂或硅油1‑2%，色粉0.5‑1%，二硫化钼2‑3%，己内酰胺65.65%‑76.6%。本发明的产品具有优异的力学性能、弯曲强度与剪切强度，低吸水率，耐高低温气候，耐腐蚀，绝缘性好；减震降噪，减少二次空气传播的声音，提高了行车的舒适性和轨道的安全性，保护道床的使用寿命，大大降低了铁路基础设施的维护成本和工作量。
