Anchoring material for sleeper screw spikes
The invention relates to an anchoring material for sleeper screw spikes. The nchoring material is characterized by comprising the following components in parts by weight: 60-110 parts of vinyl ester resin, 0.5 to 5 parts of an amine accelerator; 0.005 to 0.1 part of a free radical polymerization inhibitor; 0.5 to 5 parts of peroxide initiator, 500 to 1500 parts of continuous graded quartz sand, 100 to 500 parts of silica powder, 0.2 to 3 parts of secondary mercaptan compound, and 1 to 5 parts of leveling agent, defoamer, wetting dispersant, thixotropic agent, thickener and pigment. The situation that limit that resin spike anchoring agents in the market are single epoxy anchoring agents is broken through, the bottleneck of online rapid anchoring operation is solved, and the anchoring material is free of pollution, high in insulativity, high in early strength, high in pulling resistance, high in durability, free of corrosion to steel bars and acceptable in cost.
本发明涉及一种用于轨枕螺旋道钉的锚固材料，其特征在于按重量份数计，包含60~110份的乙烯基酯树脂，0.5~5份的胺类促进剂，0.005~0.1份的自由基阻聚剂，0.5~5份的过氧化物类引发剂，500~1500份的连续级配石英砂，100~500份的硅微粉，0.2~3份的二级硫醇类化合物，以及总质量为1~5份的流平剂、消泡剂、润湿分散剂、触变剂、增稠剂和颜料。本发明突破了市场上树脂类道钉锚固剂为环氧类锚固剂单一品种的局限，解决了线上快速锚固作业的瓶颈，是一种无污染、高绝缘性、高早期强度、高抗拔力、高耐久性、对钢筋无腐蚀且成本可接受的新型锚固胶。
