The invention provides a heat insulation layer for a low-temperature liquid cargo tank and the low-temperature liquid cargo tank, the heat insulation layer comprises a low-temperature layer, a vacuum layer and a high-temperature layer which are stacked, the low-temperature layer is close to a low-temperature liquefaction tank and is composed of a plurality of heat insulation plates, and the low-temperature layer is fixedly installed through a stud, a fixing disc, a fixing nut and the like; the vacuum layer and the stainless steel net are arranged between the high-temperature layer and the low-temperature layer, so that the heat preservation effect can be improved, and the overall structural strength between the heat preservation layers can be improved. The whole heat insulation layer structure can effectively reduce heat transfer between the liquid cargo tank and the external environment, and it is guaranteed that the liquid cargo is kept in a low-temperature state. And the protective layer on the outer surface of the high-temperature layer can protect the inner layer structure, and also can play a role in preventing moisture and water. In addition, the low-temperature layer further has the function of a shielding layer, leaked liquid can be prevented from splashing to the periphery, damage of low-temperature liquid to the surrounding structure is avoided, in addition, a leakage-proof thin film is further arranged on the inner surface of the low-temperature layer, and the safety degree is further improved.

    本发明提供一种用于低温液货舱的绝热层及低温液货舱,该绝热层包括叠置的低温层、真空层及高温层,低温层靠近低温液化舱,由多块保温板组成,低温层通过螺柱、固定盘、固定螺母等完成固定安装;高温层与低温层之间设有真空层和不锈钢网,既可以增加其保温效果,也能够增加保温层次间整体之间的结构强度。整个的绝热层结构能够有效地减少液货舱与外界环境之间的热传递,保证液货保持在低温状态。高温层外表面的保护层既能保护内层结构,同时还可以起到防潮和防水的作用。低温层还具备屏蔽层的作用,可以防止泄漏液体飞溅到周围,避免低温液体对周围结构的破坏,此外,在低温层的内表面还设有防漏薄膜,进一步提高了安全程度。
