Description

汽车顶衬制作方法、汽车顶衬和车辆Manufacturing method of automobile headliner, automobile headliner and vehicle

技术领域technical field

本发明涉及车辆技术领域，具体涉及一种汽车顶衬制作方法、汽车顶衬和车辆。The invention relates to the technical field of vehicles, in particular to a method for manufacturing an automobile roof lining, an automobile roof lining and a vehicle.

背景技术Background technique

汽车顶衬是一种安装在驾驶员和副驾驶员头顶上方，用来遮挡顶盖及侧围钣金、线束等零部件的结构，且具有一定的吸音、隔音和隔热的功能，是所有车型的标配。目前绝大多数顶衬均由面料和基材模压成型工艺制作而成。中高档乘用车的顶衬基材多选用玻璃纤维增强的PU板，这种基材的NVH性能相对较PP玻纤板等材料更优。The car roof lining is a structure installed above the heads of the driver and co-driver to cover the top cover, side panel, wiring harness and other components, and has certain functions of sound absorption, sound insulation and heat insulation. Standard on the model. At present, the vast majority of top linings are made of fabrics and substrates by compression molding. The top lining substrate of mid-to-high-end passenger cars is mostly made of glass fiber reinforced PU board. The NVH performance of this substrate is relatively better than that of PP glass fiber board and other materials.

常规顶盖隔热主要依靠顶衬和顶盖之间的空腔，若无空腔或腔内空间比较小，则隔热效果差。低密度、导热率的气凝胶可以提高隔热性，改善夏天车内温度。气凝胶是现有密度最小的固体，其基本制备原理是先制备溶胶，再使用超临界干燥去除凝胶中的溶剂，保留下完整骨架。气凝胶的孔隙率达到99.8％，密度低，空气在其孔内几乎完全静止，具有优异的轻质和隔音性，但纯气凝胶产品可加工性能和外观性能较差，不能直接喷涂在顶盖上实现隔热。Conventional top cover heat insulation mainly relies on the cavity between the top lining and the top cover. If there is no cavity or the space inside the cavity is relatively small, the heat insulation effect will be poor. Airgel with low density and thermal conductivity can improve heat insulation and improve the temperature inside the car in summer. Airgel is the solid with the lowest density. The basic preparation principle is to prepare a sol first, and then use supercritical drying to remove the solvent in the gel, leaving a complete skeleton. The porosity of airgel reaches 99.8%, the density is low, the air is almost completely still in its pores, and it has excellent light weight and sound insulation, but pure airgel products have poor processability and appearance, and cannot be directly sprayed on Heat insulation is realized on the top cover.

专利CN 205842099U记载了在车辆顶棚的背面粘设气凝胶膜，气凝胶的材质是钛钠硅绝热材料，隔热作用较好。Patent CN 205842099U records that an airgel film is attached to the back of the vehicle roof, and the material of the airgel is a titanium-sodium-silicon thermal insulation material, which has a better thermal insulation effect.

专利CN 112125697A记载了将PET纤维-二氧化硅气凝胶复合材料上下表面与增强层复合，制成可应用于汽车内饰零部件的层状复合材料，用于汽车内饰顶棚与钣金顶盖之间，替代传统的双组份吸音棉，有效隔绝车顶噪音，降低车顶振动。Patent CN 112125697A records that the upper and lower surfaces of the PET fiber-silica airgel composite material are combined with the reinforcement layer to make a layered composite material that can be applied to automotive interior parts, and is used for automotive interior ceilings and sheet metal roofs Between the covers, instead of the traditional two-component sound-absorbing cotton, it can effectively isolate the noise of the roof and reduce the vibration of the roof.

专利CN110524962A记载了将纤维网压薄，再采用针刺机刺毡，热压成型，得到汽车用气凝胶热塑性材料。此材料隔热保温性能高、抗压力、抗撕扯力强、质轻。The patent CN110524962A records that the fiber web is thinned, and then a needle-punched felt is used for hot-press molding to obtain an airgel thermoplastic material for automobiles. This material has high thermal insulation performance, strong pressure resistance, strong tear resistance, and light weight.

常规顶衬自身隔热性能较差，NVH和轻量化有提升空间。其他技术记载的气凝胶应用方案一般是将气凝胶直接制成成品后替代吸音棉或直接制成毡子，没有夹在本体中应用，未能充分发挥气凝胶材料的性能。Conventional top lining itself has poor thermal insulation performance, and there is room for improvement in NVH and lightweight. The airgel application schemes recorded in other technologies generally make the airgel directly into a finished product to replace the sound-absorbing cotton or directly make a felt, which is not clamped in the body for application, and the performance of the airgel material cannot be fully utilized.

Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

下面首先结合附图具体描述根据本发明实施例的汽车顶衬的制作方法。Firstly, the manufacturing method of the automobile roof lining according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

根据本发明实施例的汽车顶衬的制作方法，包括以下步骤：The manufacturing method of automobile roof lining according to the embodiment of the present invention, comprises the following steps:

S10、制备纤维网以及基材复合板10；S10, preparing a fiber web and a substrate composite board 10;
