Abstract

The invention discloses a polyurethane thermal insulation board for a refrigeration storage and a refrigeration box and a preparation method thereof. The polyurethane thermal insulation board comprises surface layer materials and a base material. The surface layer materials are arranged on the upper surface and the lower surface of the base material, and are fiber cloth or polycarbonate films. Thebase material formed by reaction of reinforcing fibers, a filler and a rigid polyurethane foam foaming material includes 0-60 parts by weight of the reinforcing fibers, 0-60 parts by weight of the filler and 40-80 parts by weight of the rigid polyurethane foam foaming material. The burning performance grade of the obtained polyurethane thermal insulation board is not lower than grade B2 in GB8624-2012 'classification for burning behavior of building materials and products'. The polyurethane thermal insulation board for the refrigeration storage/box has the advantages of waterproof and thermalinsulation decoration, lightweight, high strength, integral molding and continuous production and easy installation and maintenance.

Description

technical field [0001] The invention belongs to the field of cold chain technology industry, and in particular relates to a polyurethane insulation board for refrigerators and refrigerators and a preparation method thereof. Background technique [0002] Since the beginning of the new century, the storage, transportation and fresh-keeping technology of agricultural products has developed rapidly, and the environment and conditions for the development of cold chain logistics have continued to improve. However, my country's cold chain logistics system has not yet formed a system, the proportion of cold chain circulation of fresh and live agricultural products is still low, and the capacity of cold chain logistics infrastructure is seriously insufficient. Over the years, many areas, especially poverty-stricken areas, lack infrastructure such as cold storage, fresh-keeping storage, and refrigerated trucks, and various agricultural products have been seriously unsalable, causing h...
