Description

一种汽车安全带卷轴器隔音垫的制备方法及应用
技术领域
本发明涉及一种安全带卷轴配件，尤其是涉及一种汽车安全带卷轴器隔音垫的制备方法及应用。
背景技术
汽车安全带是为了在碰撞时对乘员进行约束，以及避免碰撞时乘员与方向盘及仪表板等发生二次碰撞或避免碰撞时冲出车外导致死伤的安全装置。汽车安全带又可以称之为座椅安全带，是乘员约束装置的一种。汽车安全带是公认的最廉价也是最有效的安全装置，在车辆的装备中很多国家是强制装备安全带的，其中用于安全收卷的芯轴是其关键部件，通常卷轴采用注塑成型。
安全带在收卷或拉出过程中会因卷轴器转轴的转动产生噪音，这会严重的影响汽车安全带的使用体验感，特别是全带卷轴器在长时间使用后噪音问题会愈加突出，特别是在高档车的应用环境内更是需要解决的问题，目前市场的汽车安全带卷轴器(三厢车乘用车后排的安全带卷轴器)没有专们设计的隔音隔热垫，目前市场空白。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷而提供严重隔音效果好、安装方便的汽车安全带卷轴器隔音垫的制备方法。
本发明的目的可以通过以下技术方案来实现：
本发明中汽车安全带卷轴器隔音垫的制备方法，包括以下步骤：
S1：半制品重层片材制造成型
S1-1：密炼，将橡胶粒子、塑料粒子、添加剂、炭黑和矿物填充物放入密炼机中密炼；
S1-2：挤出，将密炼后的产物放入螺杆挤出机中，挤出，得到半制品重层片材；
S2：半制品重层吸塑成型
将半制品重层片材烘干，通过吸塑模真空成型，冷却，得到半制品重层；
S3：发泡成型
以半制品重层片材为骨架，通过发泡原料在半制品重层片材上发泡成型，得到卷轴器隔音垫成品。
进一步地，S1-1所述的橡胶粒子为EPDM，所述的塑料粒子为TPO与PE的混合颗粒，所述的添加剂为加工添加剂：白油和抗氧剂1010&168，所述的矿物填充物为硫酸钡与碳酸钙的混合物。
进一步地，S1-1中所述的橡胶粒子、塑料粒子、添加剂、炭黑和矿物填充物的质量比为(8～12％)：(12～19％)：(3～5％)：(0.1～0.3％)：(68～72％)。
进一步优选地，S1-1中所述的橡胶粒子、塑料粒子、添加剂、炭黑和矿物填充物的质量比为10％：15％：4％：0.2％：70.8％。
进一步地，S1-1的密炼温度为150～200℃，密炼时间为10～30min。
进一步地，S1-2中的挤出机的螺杆温度为150～200℃，磨头温度为200℃，获得的片材的厚度为1～2mm。通过磨头设备控制挤出片材宽度和厚度，设置寄出过程中各个分区温度，并通过磨头微调得到适宜的挤出速度。
进一步地，S2中的烘干温度为160～200℃，烘干温度为40～60s。
进一步地，S3中所述的发泡原料为聚醚和异氰酸酯，聚醚和异氰酸酯的质量比为(90～110)：(50～65)。
进一步地，S3中发泡的压缩强度为65-90kg/m3，发泡压缩强度为5-15kPa。
进一步地，S3中获得的卷轴器隔音垫成品的厚度为10-15mm。
上述方法制备的汽车安全带卷轴器隔音垫在具体应用时，直接将卷轴器隔音垫成品包覆于汽车安全带卷轴器上，实现隔音效果。
与现有技术相比，本发明具有以下优点：
1)通过包覆本技术方案制备的汽车安全带卷轴器隔音垫，使得安全带在拉伸和收缩过程中其轴杆发出的噪音显著降低，显著的提升了车内安全带使用的体验感。
2)本技术方案中将以改性塑胶的半制品重层片材为骨架，通过发泡原料在半制品重层片材上发泡成型，使得转轴产生的大部分噪音在双层发泡层和骨架层中被吸收耗散，得到卷轴器隔音垫成品，可适配于各种汽车安全带卷轴器的安装。
3)本技术方案整体工艺流程简单，各组分配方如橡胶粒子、塑料粒子、添加剂、炭黑，发泡原料均为工业常用廉价原料，使得本安全带转轴器隔音垫可实现大规模的工业化生产。
