Abstract
The invention discloses a method for preparing environmentally-friendly polyurethane plastic for a track. Polyether polyol, isocyanate, MDI (diphenyl methane diisocyanate), a polyurethane vulcanizing agent, a plasticizer, padding and pigments are taken as the main raw materials for preparing the polyurethane plastic. The method comprises the following steps of: preparing a polyurethane prepolymer through reaction of polyether polyol and liquefied MDI under the condition of vacuum dewatering; then adding a chain extender, after heating and vacuum degassing, adding the plasticizer, the padding, an antiager, and the pigments, and preparing the polyurethane plastic through stirring and grinding. The method has the advantages of being simple and easy to operate, and the prepared plastics have the characteristics of being good in overall performance, non-toxic, tasteless, and environmentally-friendly.
