Prefabricated slab type ballastless track high polymer isolating layer material and application
The invention discloses a prefabricated plate type ballastless track high polymer isolation layer material and application. Comprising the following components in parts by mass: 75-85 parts of ethylene propylene diene monomer, 15-25 parts of a nitrile rubber plastic alloy material, 4-7.5 parts of an activating agent, 1-3 parts of a heat stabilizer, 0.5-1.5 parts of a chemical anti-aging agent, 0.5-1 part of a physical anti-aging agent, 40-60 parts of carbon black, 5-10 parts of fumed silica, 35-25 parts of CaCO3, 25-35 parts of an environment-friendly plasticizer, 1-1.5 parts of a vulcanizing agent, 1.8-2.7 parts of an accelerant, 12-23 parts of paraffin oil, 2-2.5 parts of zinc oxide, 1-1.5 parts of stearic acid, 0.8-1.5 parts of an anti-aging agent TMQ, 0.4-0.5 part of sulfur and 0.3-0.5 part of urea grease BK. According to the invention, through polymerization of the ethylene propylene diene monomer and the nitrile rubber plastic alloy material, the comprehensive mechanical property effect of the product can be ensured, the material of the isolating layer has good pressure, is not easy to damage and does not crack, and the excellent rebound resilience of the product is ensured, so that the product is not easy to puncture in the use process, and the service life of the product is prolonged.
本发明公开一种预制板式无砟轨道高聚物隔离层材料及应用，包括如下质量份数组份：三元乙丙橡胶75～85份、丁晴橡塑合金材料15～25份、活化剂4～7.5份、热稳定剂1～3份、化学防老剂0.5～1.5份、物理防老剂0.5～1份、炭黑40～60份、气相法白炭黑5～10份、CaCO35～25份、环保增塑剂25～35份、硫化剂1～1.5份、促进剂1.8～2.7份、石蜡油12～23份、氧化锌2～2.5份、硬脂酸1～1.5份、防老剂TMQ0.8～1.5份、硫磺0.4～0.5份、尿素脂BK0.3～0.5份。本发明通过三元乙丙橡胶与丁晴橡塑合金材料的聚合能够在保证产品综合力学性能效果的同时，使隔离层材料具备良好的受压不易破损、不产生龟裂，保证产品优良的回弹性能，从而使产品在使用过程中不易被刺穿，延长产品的使用寿命。
