Problems solved by technology

As the evaporation rate of low-temperature storage tanks and fuels gradually increases, it is necessary to increase the thickness of the insulation to ensure its evaporation, which will directly reduce the storage capacity of the liquid tank. At the same time, as the thickness of the insulation board becomes thicker, the raw materials Insulation at higher temperatures is not as effective
It is conceivable that the material properties of existing raw materials have gradually failed to meet market requirements

Abstract

The invention relates to a heat and cold insulating composite board and layer for a liquefied gas low-temperature storage tank. The heat and cold insulating composite board comprises a vacuum board, apolyurethane board and a polyurethane foam-sprayed layer. The vacuum board is bound to the polyurethane board, polyurethane is foam-sprayed to the polyurethane board and the vacuum board, the polyurethane foam-sprayed layer is formed, the vacuum board is wrapped by the polyurethane foam-sprayed layer and the polyurethane board, and a sandwich structure is formed. Compared with the prior art, theheat preservation performance is excellent, the heat preserving effect of the heat preserving composite board to which the vacuum board is added is better under the low-temperature condition, the samethickness and the same condition and is at least 2 times of the original heat preserving effect, the requirement of the low-evaporation-rate storage tank can be met, and losses of liquid in the storage tank are reduced. Meanwhile, the heat and cold insulating composite board and layer have the beneficial effects that the manufacturing process is convenient, the use range is wide, the capacity ofthe storage tank is increased, mounting is convenient and rapid, the plasticity is high, and the cost is low.

Description

technical field [0001] The invention relates to a heat-insulating and cold-preserving composite board and a composite layer for a low-temperature storage tank of liquefied gas, belonging to the technical field of composite boards. Background technique [0002] At present, for the insulation of some low-temperature storage tanks and fuel tanks on the market, polyurethane spray foam and insulation boards are used for insulation. Its raw material is polyurethane or polystyrene. As the evaporation rate of low-temperature storage tanks and fuels gradually increases, it is necessary to increase the thickness of the insulation to ensure its evaporation, which will directly reduce the storage capacity of the liquid tank. At the same time, as the thickness of the insulation board becomes thicker, the raw materials The insulation effect at higher temperatures is not good. It is conceivable that the material properties of existing raw materials have gradually failed to meet market re...
