Description

3D环形真空绝热板和保温容器 技术领域
本发明涉及保温材料领域，具体是指一种3D的真空绝热板。
背景技术
目前真空绝热板多为二维平板型，大多用于矩形容器的保温，也有将平板拼接成环形的VIP板，但其工艺复杂，对本身VIP的阻隔膜亦有损伤，影响VIP性能及寿命。平板VIP拼成环形结构，此结构VIP板拼接处的漏冷严重，影响了整体的绝热性能；且内层阻隔膜的褶皱，极大提高了VIP板的漏气比例，提高了VIP的使用成本。VIP的应用带来的保温性能提升的不理想，以及不良率较高，限制了VIP在环形保温领域的应用。
发明内容
本发明的目的在于解决平板VIP在环形保温应用上的性能不足以及不良率高，提供一种环形真空绝热板，应用在环形容器或管道的保温上，没有拼接部位的漏冷，极大增强保温性能，同时保证了VIP的良率，从而提高VIP应用的性价比，更加节能环保。
为了解决上述技术问题，本发明提供了一种3D环形真空绝热板，包括：内＝阻隔层、中间芯材、外阻隔层；
所述内阻隔层为环形，其沿着轴向的两端为开口面；所述外阻隔层包括沿着内阻隔层的径向外凸的外凸部分、以及沿着内阻隔层的轴向设置在外凸部分上下两侧的平直部分；所述平直部分与内阻隔层复合以在所述外凸部分与内阻隔层之间形成用于填充中间芯材的真空密闭空间。
在一较佳实施例中：所述内阻隔层为金属材质或为铝塑膜材质；在真空条件下，内阻隔层的氦质谱漏率小于10 -4Pa.l/s.cm 2。
在一较佳实施例中：所述中间芯材为一体成型，或为平板芯材卷成圆环形。
在一较佳实施例中：所述外阻隔膜为金属材质或为铝塑膜材质；在真空条件下，所述外阻隔膜的氦质谱漏率小于10 -4Pa.l/s.cm 2。
本发明还提供了一种保温容器，使用了如上所述的3D环形真空绝热板。
相较于现有技术，本发明的技术方案具备以下有益效果：
1.通过将VIP板制成3D环形结构，可直接将环形的绝热需求完全包裹，不留缝隙，避免了平板VIP板拼接形成的缝隙，从而大大提高VIP实际保温效果，从而提高保温时长。
2.内阻隔层可为金属材质，可直接应用于高温绝热领域如热水器储水桶，解决了铝塑膜不能直接接触高温物体的问题。
3.被包裹的内胆为金属内胆，可采用食品级金属，直接接触食品、生鲜及药品。相当于直接用保温材料将物品包裹，大大提高绝热性能及应用场景。
4.当内层采用铝塑阻隔膜时，避免了内层阻隔膜的过渡褶皱，提高了产品的良率，降低了成本。
