| titleOfInvention | Cold-resistant polyurethane cushion plate for heavy haul railway and preparation method thereof |
| abstract | The invention relates to the technical field of polyurethane materials, in particular to a cold-resistant polyurethane cushion plate for a heavy haul railway and a preparation method thereof. The weight ratio of A component to B component is 100: (91-107) by mass; the component A comprises the following raw materials: polyol A, a chain extender and an auxiliary agent; the component B comprises the following raw materials: polyol B, diisocyanate and a polymerization inhibitor. The cold-resistant polyurethane backing board has excellent mechanical property, lower compression permanent deformation and dynamic-static ratio and better vibration reduction effect. In addition, the polyurethane elastic base plate has lower low-temperature brittleness temperature, meets the use requirement, has excellent low-temperature resistance, and is suitable for the construction of railways in cold regions such as Xinjiang, inner Mongolia and northeast China. |
