Abstract:
      Taking styrene butadiene rubber/high vinyl rubber and ethylene-propylene-diene rubber floor cloths as the research objects，the total volatile organic compound（TVOC） emission of the rubber floor cloth （referred to as floor cloth） for rail transit vehicle was analyzed，and its control method was studied. The results showed that the long-time（6～8 months） parking of compounds and baking and parking of the floor cloth played good roles in reducing the TVOC emission of the floor cloth. The TVOC emission of the floor cloth could be controlled about 1. 5 mg·m-3 after natural parking for 60～70 d. The TVOC emission of the floor cloth with different sampling positions varied greatly through the whole roll vertical baking method，and this baking method made it difficult to effectively control the TVOC content of the floor cloth. The singlelayer continuous baking method could reduce the TVOC emission of the floor cloth. Scientific compound formulation design and lean processing technology were effective ways and research directions to reduce TVOC content of the floor cloth.
