The invention discloses a heat preservation compartment plate for a refrigerator truck, belonging to the field of heat preservation plate production. The compartment plate disclosed by the invention is of a hexahedral totally-enclosed structure, and is produced through the following processes of I1) feeding bottom-layer glass fiber materials, heat preservation layer materials, surface-layer glass fiber materials and side glass fiber materials according to a compartment plate shape and compartment plate opening situations; (2) sequentially laying the bottom-layer glass fiber materials, the heat preservation layer materials and the surface-layer glass fiber materials from bottom to top in a mold, and laying the side glass fiber materials between each of the bottom-layer glass fiber materials, the heat preservation layer materials and the surface-layer glass fiber materials and the side wall of the mold; (3) performing vacuumization operation in the process of heating and pressurizing, and obtaining the heat preservation compartment plate with the hexahedral totally-enclosed structure through one-step forming, wherein the forming temperature is 60-70 DEG C, the forming pressure is 0.8-1.2 kg/cm<2>, and the vacuumization operation is performed to -0.25 to -0.15 MPa. Compared with the prior art, the heat preservation compartment plate for the refrigerator truck disclosed by the invention has the features of light weight and high strength, and has excellent popularization application values.
