Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation of gas tank trucks, in particular to a foaming tooling for high-pressure liquefied gas tanks. Background Art

[0002] The general structure of a high-pressure liquefied gas tank truck is a single-layer or double-layer cylindrical structure. One type is to use a foaming mold to prepare the polyurethane foam layer after the inner cylinder is made, and finally wrap it with a thin aluminum plate for protection; the other type is to draw a vacuum between the inner and outer cylinders to reduce external heat transfer. At the same time, it is supplemented by pearl sand filling technology or insulation paper wrapping technology to further enhance the insulation effect.

[0003] Of the two types of high-pressure liquefied gas tanker structures mentioned above, the former is more favored by customers due to its multiple advantages, such as simple manufacturing process, easy to control the quality of the insulation layer, lightweight and strong economy. Therefore, among the current domestic high-pressure liquefied gas tanker products, especially liquid carbon dioxide transport vehicles, there are still many that choose and use polyurethane foam structures for insulation. In the existing foaming tooling, the arc is manually trimmed after the foam is cooled, and then the outer surface is coated with waterproofing. In this process, not only a large amount of manpower and material resources are consumed to reduce production efficiency, but also the manual application of waterproofing cannot guarantee the integrity of the waterproof layer, resulting in the penetration of moisture in the atmosphere into the gaps when the product is running, and the phenomenon of ice accumulation gradually occurs, which seriously reduces the cold preservation effect of this part.
