摘　　要：以丁苯橡胶/高乙烯橡胶和三元乙丙橡胶地板布为研究对象,对轨道交通车辆橡胶地板布(简称地板布)的挥发性有机化合物(TVOC)释放量进行分析并探究其控制方法。结果表明:混炼胶长时间(6~8个月)停放及地板布烘烤加晾放均对减小地板布的TVOC释放量起到良好作用,地板布自然停放60~70 d,其TVOC释放量基本可以控制为约1.5 mg·m^(-3);整卷竖立式烘烤方式的地板布卷材取样部位不同,地板布的TVOC释放量差异较大,该烘烤方式难以有效控制地板布的TVOC含量;单层通过式连续烘道烘烤方式可减小地板布的TVOC释放量;科学的胶料配方设计及精益化的加工工艺是减小地板布的TVOC含量的有效途径和研究方向。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 single-layer 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.
