Refrigerated transport car, composite insulation board and manufacturing method of composite insulation board

Abstract

The invention discloses a composite insulation board, comprising an inner wall plate, an outer wall plate and a heat-insulated combination layer, wherein the heat-insulated combination layer is fixedly arranged between the inner wall plate and the outer wall plate and comprises reinforcing ribs, a vacuum heat-insulating board, an inner protection layer and an outer protection layer; the inner protection layer and the outer protection layer are fixed at two sides of the vacuum heat-insulating board; the reinforcing ribs are respectively embedded into the inner protection layer and the outer protection layer; and the inner protection layer and the outer protection layer are respectively connected with the inner wall plate and the outer wall plate. The invention also discloses a refrigerated transport car using the composite insulation board disclosed by the invention and a manufacturing method of the composite insulation board. The vacuum heat-insulating board and a rigid polyurethane board are used together; comprehensive cold broken bridge treatment is carried out on inner and outer parts of the composite insulation board, so that the heat insulation and preservation performances are improved and the weight is light. The strength of the composite insulation board is improved by arrangement of a reinforcing layer, and the inner protection layer and the outer protection layer can effectively prevent the vacuum heat-insulating board from being punctured; therefore, the composite insulation board has a long service life, a broad market application and popularization prospects.

Description

technical field [0001] 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. Background technique [0002] 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. [0003] 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. [0004] Internal insulation materials mainly include expanded polystyrene (EPS), soft expanded polyethyl...

AI Technical Summary

Problems solved by technology

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 (Vacuum Insulation Panel, referred to as VIP panel) is related to the core material, generally below 0.01w / (m·k), and its thermal insulation performance is superior to polyurethane rigid foam material And the weight is light, but because the vacuum insulation board is easily punctured, its own strength is low, and it cannot meet the strength requirements of the refrigerated transport car body and has not been applied to the refrigerated transport car body
