Secondary foaming rail transit base plate and preparation method and application thereof
The invention discloses a secondary foaming rail transit base plate. The secondary foaming rail transit base plate comprises the following raw materials in parts by weight: 100 parts of EPDM, 20-30 parts of butadiene rubber, 40-50 parts of carbon black, 25-35 parts of silica, 0.4-0.7 part of an accelerant, 3-5 parts of a foaming agent, 3-5 parts of a bridging agent, 1-2 parts of a dispersing agent, 3-5 parts of an active agent, 1-1.5 parts of stearic acid, 4-6 parts of zinc oxide, 30-40 parts of paraffin oil and 1-1.5 parts of insoluble sulfur. According to the rail transit base plate, a halogen content is greatly reduced, and environmental protection requirements are met; meanwhile, after the base plate is used, vibration and noise reduction effect on rail is good; and the base plate hashigh smoothness, excellent stability and excellent aging resistance, applicability to a wide high and low temperature range, extremely low shrinkage rate after used in an environment with a temperature of -60 DEG C to 120 DEG C for a long time, a small compression deformation rate and static rigidity of smaller than 30 KN/mm.
本发明公开了一种二次发泡轨道交通垫板，包括以下重量份配比的原料：EPDM100份、顺丁橡胶20～30份、碳黑40～50份、硅土25～35份、促进剂0.4～0.7份、发泡剂3～5份、架桥剂3～5份、分散剂1～2份、活性剂3～5份、硬脂酸1～1.5份、氧化锌4～6份、石蜡油30～40份、不溶性硫磺药胶1～1.5份;本发明交通垫板大大降低了卤素的含量，符合环保要求，同时使用本发明的垫板后，轨道减振降噪效果好并具有优良的高平顺性、稳定性、耐老化性能、耐高低温范围广，在‑60℃～120℃环境长期使用时收缩率极低，压缩变形率小，静刚度小于30KN/mm。
