Description

一种减振毯
技术领域
本发明涉及一种汽车内饰材料技术领域，尤其是涉及一种减振毯。
背景技术
汽车内部通常会用到不同类型的地毯，有的由毯面、毛毡租成，有的由毯面、EVA、毛毡组成，而也有的由毯面、EPDM和PU组成。根据声学性能的要求不同，客户会选择不同类型的地毯。而无论哪种类型的地毯，通常都不会缺少毯面。毯面主要有两种类型：簇绒毯和针刺毯。簇绒毯一般用于中高端车型，价格比较高；而针刺毯常用于平民车型。毯面不但有理化性能的要求，近年来对声学性能的要求也越来越高。
公开号为：CN104321478的中国专利公开了一种中空纤维在针刺地毯上的应用，该发明中至少包括一个由短纤维制成的作为顶层的针刺表面层，短纤维中包括中空纤维。与普通针刺毯相比，中空纤维针刺毯的耐磨性能占有明显优势，但声学性能并没有多大提升。
限于目前对于吸声材料中微观结构和吸声原理的认知水平，目前市场中生产的毯面材料基本都仅仅着眼于其隔声性能的改善，但是，一种材料整体的声学性能不光与其隔声性能有关，还与其吸声性能密切相关。材料的吸声性能主要取决于声波在其本体结构中传播的耗散，即与组成吸声材料的纤维种类、纤维直径和纤维强度密切相关。传统毡类毯面材料，通过背胶的设计如淋不同克重的胶膜层或者复合不同克重的薄膜，往往可以取得很高的隔声性能，但这必然会牺牲掉毯面的吸声性能。对于改善车内吸声性能，传统毯面材料通常已没有更好的办法，使得传统车用毯面材料在应用时具有一定的局限性。
随着自动驾驶技术的发展，乘客的注意力会从驾驶转移到驾乘体验上，对车辆舒适性要求会越来越高，对车内吸声和隔声的需求只增不减。在客户需求的驱动下，本领域的技术人员需要研发一种既能发挥很高的隔声性能，又能保持很好的吸声性能的减振毯面，提升车内的声学品质。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种既能发挥很高的隔声性能，又能保持很好的吸声性能的减振毯，以满足车辆等交通工具的高端化、私密化需求，减少对于人耳的噪声危害。
为达此目的，本发明采用以下技术方案：
一种减振毯，所述减振毯至少包括一个表面层，所述表面层由短纤维和极细纤维混合制成，其特征在于：所述极细纤维的线密度为0.02dtex～0.5dtex，按重量百分数计算，所述极细纤维的含量≥8wt％。
特别地，所述短纤维由热塑性材料制成，所述热塑性材料为聚丙烯腈纤维、腈纶、聚对苯二甲酸乙二醇酯(PET)、聚对苯二甲酸丁二醇酯(PBT)、聚对苯二甲酸丙二醇酯(PTT)、丙纶(PP)或者聚酰胺(PA)的任一种或几种。
特别地，所述短纤维的线密度为1～20dtex，优选为4～10dtex。
特别地，所述短纤维的长度在25mm～130mm之间，优选为40～90mm。
特别地，所述减振毯中的表面层为丝绒、无定向丝绒或平坦的表面的任一种。
特别地，所述表面层具有100～2000g/m2的面积重量。
一种减振毯，所述减振毯包括上述表面层，所述表面层的底部设置有粘结介质层，所述粘结介质层通过底部的粘结层与表面层粘结为一体。
特别地，所述粘结介质层为无纺布层或泡沫层的任一种。
特别地，所述粘结层由胶膜或者胶粉制成，所述胶膜或者胶粉由PE、PP或EVA制成。
特别地，所述减振毯用于制备汽车或轨道交通车辆中的覆盖物，特别是用做主地毯、内控制板区域、地板垫、座椅靠背、行李架的覆盖物，或者用作车尾箱或行李箱中的区域的覆盖物。
本发明的有益效果为，与现有技术相比所述减振毯能够发挥很高的隔声性能，同时具有很好的吸声性能。能满足车辆等交通工具的高端化、私密化的需求，减少对于人耳的噪声危害。
