The invention provides a B-type independent liquid cargo tank mixed insulation structure which comprises a leakage containing cavity and an insulation layer supporting structure composed of an inverted semicircular leakage groove and a plurality of insulation boards which are arranged in the circumferential direction and are in specific shapes, and the overall mixed insulation structure is formed by combining on-site foaming and spraying polyurethane. The mixed insulation structure meets the IGC standard requirement, is good in sealing performance, not prone to overall cracking, good in heat insulation and heat preservation effect compared with a plate type heat preservation structure, short in construction period and low in cost. And particularly, the insulating material does not fall off on the vertical surface of the large B-type cabin, and the service life is long.
本发明提供了一种B型独立液货舱混合式绝缘结构,包括:用倒半圆型泄漏槽和几道周向布置的特定形状的保温板构成泄露容纳腔和保温层支撑结构,并用现场发泡喷涂聚氨酯结合形成整体混合式绝缘结构。该混合式绝缘结构满足IGC规范要求,密封性好,整体不易开裂,绝热保温效果好于板式保温结构,且施工周期短,成本低;强度优于整体现场发泡喷涂式保温结构,尤其是在大型B型舱垂直面上绝缘材料不脱落,寿命长。
