The exterior wall thermal insulation materials on the market at present are various, and can be divided into three categories, namely inorganic thermal insulation materials, organic thermal insulation materials and composite materials according to material properties.

The rock wool has the advantages of good heat insulation, sound absorption, fire prevention and the like, and is a main energy-saving material, but the rock wool is easy to absorb water and pulverize, influences the heat conductivity coefficient and reduces the heat insulation performance. The organic heat-insulating material includes moulded polyphenyl board, extruded polyphenyl board, phenolic foam, hard foamed polyurethane, etc. The organic heat-insulating material has low heat conductivity and large thermal resistance, can play a good heat-insulating role, but has poor flame retardance. The composite heat-insulating material comprises a metal sandwich plate and a metal heat-insulating splint, wherein a core material of the metal sandwich plate is polyphenyl particles, vitrified micro bubbles and the like, and the core material of the metal sandwich plate is rock wool and other heat-insulating materials with certain rigidity.

The insulation board of the refrigeration house is also a common engineering construction material, and plays an important role in engineering projects. The existing common insulation board for the refrigeration house is a polyurethane insulation board, and is a sandwich board for producing polyurethane foam as an insulation material. The thickness of the polyurethane freezer insulation board is generally between 100 mm and 300mm, and the polyurethane freezer insulation board is formed by mixing polyurethane black and white materials according to a certain proportion on site and extruding foam into a mould by high-pressure equipment for foaming. However, the polyurethane foam material of the refrigeration house can have size change (generally shrinkage) under severe temperature change or long-term low temperature, the size change is usually reflected as foam cracking or falling off, and the foam is easy to age and shrink when meeting air to generate cold bridges, and the normal use of the refrigeration house is necessarily influenced.
