The invention provides a low-temperature thermal insulation plate of a refrigerator car and a manufacturing method thereof. The thermal insulation plate comprises an outer thermal insulation layer, the inner side of the thermal insulation layer is connected with an outer cementing layer in a bonding mode, the inner side of the cementing layer is connected with a metal layer, the inner side of the metal layer is connected with an inner cementing layer, the inner side of the inner cementing layer is connected with the middle heat preservation layer of the thermal insulation plate, the whole thermal insulation plate is centered on the middle heat preservation layer, the two outer sides of the whole thermal insulation plate are symmetrically arranged, and the outermost layer of the thermal insulation plate is wrapped by a PVC cow leather layer. The thermal insulation plate has high low-temperature resistance, does not deform, expand, shrink or leak air at the temperature ranging from-30 DEG C to-40 DEG C, has certain impact resistance, can meet the strength requirement of a long-distance cold chain transport vehicle, and is suitable for being popularized and used in refrigerator cars.

    本发明提供了一种一种冷藏车的低温隔温板及其制作方法,该隔温板包括外层的隔温层,所述隔温层的内侧粘合连接有外胶合层,所述胶合层的内侧连接有金属层,所述金属层的内侧与内胶合层连接,内胶合层的内侧与隔温板的中间保温层相连接,整个隔温板以中间的保温层为中心,两外侧对称布置,隔温板的最外层由一层PVC牛皮层包裹。该隔温板具有较强的抗低温能力,能够在‑30℃‑‑40℃之间不变形,不膨胀,不收缩,不漏气,且具有一定的抗冲击能力,能够满足长途冷链运输车的强度要求,适合在冷藏车中推广使用。
