【摘要】 分析黄麻和聚丙烯纤维各自的特性,选用合理的混纺比开发汽车顶棚内饰衬板。探讨了该材料研制过程中的工艺路线及脱胶、阻燃、开松混合、梳理成网、异位对刺固结、热压等主要工艺的技术参数,将生产出的黄麻复合衬板和玻璃增强复合塑料的性能进行了比较,结果表明,用阻燃处理的黄麻纤维与聚丙烯纤维混合开发的非织造汽车内饰衬板材料,其性能指标满足汽车行业的要求,且在顶破强力、延伸性、透气性等方面优于复合塑料。更多还原

【Abstract】 The characteristics of jute and polypropylene fibers were analyzed respectively,and the reasonable blending ratio of the two fibers was determined for development of automobile interior ceiling lining boards.The processing route and chief technical parameters such as degumming,flame retardant treatment, opening and mixing,carding and web forming,take-in operation,curing and hot pressing were investigated during the development of the material.The properties of the jute and polypropylene composite lining board were compared with those of the glass fiber reinforced plastic composite and the results indicated that the performance indexes of the automobile interior lining board of jute and polypropylene non-woven composite material can meet the related requirements of the automobile industry with such properties as bursting strength,extensibility and permeability exceeding those of the glass fiber reinforced plastic composite.更多还原
