Track foaming vibration reduction base plate and preparation method thereof
The invention relates to the field of foaming vibration reduction base plates, in particular to a track foaming vibration reduction base plate and a preparation method thereof.The track foaming vibration reduction base plate is formed by laminating a first layer of material, a second layer of material and a third layer of material in a sheet shape and then conducting mold closing and vulcanization; the first layer material is one-time vulcanized rubber, and the rubber comprises the following raw materials in parts by weight: 40-50 parts of ethylene propylene diene monomer, 1-3 parts of a vulcanizing agent, 3-5 parts of a vulcanization accelerator, 20-30 parts of carbon black, 5-10 parts of paraffin oil and 1-3 parts of a microsphere foaming agent; the second layer is made of non-foaming low Mooney rubber; and the third layer is made of modified PET geotechnical cloth. The track foaming vibration reduction base plate prepared by the invention is high in flatness, uniform in foaming, proper in foam hole density, good in water resistance, good in cohesiveness between layers, not easy to fall off and easy to industrialize.
本发明涉及发泡减振垫板领域，具体涉及一种轨道发泡减振垫板及其制备方法，其中，所述轨道发泡减振垫板由第一层材料、第二层材料和第三层材料呈片状叠合后经合模硫化而成；所述第一层材料为一次硫化的橡胶，按重量份计，所述橡胶包括以下原料，三元乙丙橡胶40‑50份、硫化剂1‑3份、硫化促进剂3‑5份、炭黑20‑30份、石蜡油5‑10份、微球发泡剂1‑3份；所述第二层材料为非发泡低门尼橡胶；所述第三层材料为改性PET土工布。本发明制备得到的轨道发泡减振垫板平整度高、发泡均匀、泡孔密度合适、耐水性能好且各层之间粘结性好、不易脱落，容易实现工业化。
