Description
技术领域technical field
本发明涉及一种复合板材保温技术，特别涉及一种冷藏运输车厢、复合保温板及其制造方法。The invention relates to a thermal insulation technology of a composite board, in particular to a refrigerated transport carriage, a composite thermal insulation board and a manufacturing method thereof.
背景技术Background technique
冷藏运输车厢用于易腐产品的运输，其围护结构主要包括厢体壁面材料和内部隔热材料两大部分。The refrigerated transport compartment is used for the transportation of perishable products, and its enclosure structure mainly includes two parts: the wall material of the compartment and the internal insulation material.
传统厢体壁面材料主要是钢板，随着技术的发展，冷藏运输车厢体的内外围护结构壁面材料越来越多采用耐气候、耐辐射、耐腐蚀的碳素铝合金板、玻璃纤维或镀铝锌彩钢板。The wall surface material of the traditional car body is mainly steel plate. With the development of technology, more and more wall materials of the inner and outer protective structure of the refrigerated transport car body are made of carbon aluminum alloy plate, glass fiber or plated with weather resistance, radiation resistance and corrosion resistance. Aluminum zinc color steel plate.
内部隔热材料主要有发泡聚苯乙烯（EPS）、软发泡聚乙烯（PEF）、挤塑聚苯乙烯泡沫塑料（XPS）和聚氨酯硬质泡沫材料（PU）。目前冷藏运输车厢体大都采用聚氨酯硬质泡沫材料作为隔热材料，一般导热系数在0.03w/（m·k）左右。为保证良好的隔热保温效果，通常需要采用较厚的聚氨酯硬质泡沫材料板，导致厢体可利用容积率较小，而且能耗高。新型隔热材料真空隔热板（VacuumInsulationPanel，简称VIP板）的导热系数大小与芯材有关，一般都在0.01w/（m·k）以下，其绝热性能要比聚氨酯硬质泡沫材料优越且质量轻，但由于真空隔热板容易被刺破，本身强度低，不能满足冷藏运输车厢体的强度要求而没有得到应用于冷藏运输车厢体上。Internal insulation materials mainly include expanded polystyrene (EPS), soft expanded polyethylene (PEF), extruded polystyrene foam (XPS) and polyurethane rigid foam (PU). At present, most of the refrigerated transport vehicles use rigid polyurethane foam as the heat insulation material, and the general thermal conductivity is about 0.03w/(m·k). In order to ensure a good heat insulation effect, it is usually necessary to use a thick polyurethane rigid foam material board, resulting in a small usable volume ratio of the box body and high energy consumption. The thermal conductivity of the new insulation material vacuum insulation panel (VacuumInsulationPanel, referred to as VIP board) is related to the core material, generally below 0.01w/(m k), and its thermal insulation performance is superior to that of polyurethane rigid foam material. Lightweight, but because the vacuum insulation board is easily punctured, its own strength is low, it cannot meet the strength requirements of the refrigerated transport car body and has not been applied to the refrigerated transport car body.
