The invention discloses a production process of rubber and plastic products without prohibited and restricted substances for locomotives. S1. Making rubber and plastic products without prohibited and restricted substances. S2. Banburying: the weighed materials are put into a banburying chamber for denseness. Refining, get No. 1 glue, S3, cutting glue: Pour No. 1 glue into the open mill and completely thin and pass it twice to cool down, then put into the automatic swinging rack, turn the glue and slice it, S4, start training: put No. 1 film into the open mill , S5, extrusion: using twin-screw extruder, S6, trimming: extruding the rubber material and then pulling and calendering to adjust the size; S7, plate making: the molding material is sent into a multi-section drying oven to foam out the rubber plate , S8, cooling, S9, die cutting: cut according to size requirements. The product of the invention does not contain prohibited substances, does not harm the human body, has less volatile substances, and has low odor; does not contain antimony trioxide, halogen flame retardants and other substances, and has low smoke density and low smoke toxicity during combustion. It adopts organic intumescent flame retardant, which has good compatibility with rubber and plastic. |
