Abstract

The invention relates to a refrigeration and heat preservation composite board. The composite board comprises a heat preservation layer, the top and the bottom of the heat preservation layer are connected with panel layers through adhesive layers, the surfaces of the two panel layers are coated with gel coat layers, and the gel coat layers comprise, by weight, 15-20 parts of a vinyl acetate emulsion, 10-15 parts of epoxy resin, 12-16 parts of glycerinum, 2-8 parts of an anti-aging agent, 1-3 parts of a leveling agent, 5-6 parts of a coalescing agent, 0.5-0.8 part of a dispersing agent, 0.1-0.2 part of a defoaming agent, 0.8-1.2 parts of a preservative and 0.1-0.3 part of a stabilizing agent. The glass steel plate is adopted as the panel, polyurethane is directly foamed and filled to form the heat preservation layer, the weight is light, the strength is high, the rigidity is good, the sound insulation performance and the heat preservation performance are good, and the problems that a traditional plate material is not easy to clean, prone to concave deformation, poor in durability, prone to abrasion and poor in anti-collision performance are solved. The glass steel plate is water-impermeable the closed porosity of the rigid polyurethane foam is greater than 90%, and the composite board has good chemical stability to atmosphere, water and media such as acid, alkali and salt with general concentration due to a gel coat layer.

Description

technical field [0001] The invention relates to the technical field of composite board processing technology, in particular to a refrigeration and thermal insulation composite board and its processing technology. Background technique [0002] A refrigerated truck refers to a closed van transport vehicle used to maintain the temperature of frozen or fresh goods. A refrigerated vehicle is a special refrigerated transport vehicle equipped with a refrigeration unit refrigeration unit and a polyurethane insulated compartment. The refrigerated vehicle can be used according to the manufacturer, chassis Carrying capacity and compartment type are classified. The box of refrigerated trucks usually uses composite panels to improve the thermal insulation effect of items. However, the surface of current refrigerated thermal insulation composite panels is not easy to clean, easy to dent and deform, poor durability, easy to wear, and anti-collision Poor performance. For this reason, we pr...
