Therefore, a material for filling the gap between the refrigerating duct 2 and the refrigerating liner 6 is required.
The sealant 4 in the application is polyurethane foam, and the sealant 4 is prepared from polyether polyol and isocyanate according to a mass ratio of 1.8-1.
The polyurethane is a high molecular compound and is named polyurethane. The sealant 4 in the application is compressible polyurethane foam rubber, is a special polyurethane product which is prepared by filling components such as polyurethane prepolymer, foaming agent, catalyst and the like into a pressure-resistant aerosol can, and is often used for installing joint filling, bonding, leaking stoppage, heat preservation, sound insulation and water prevention.

In some embodiments, the isocyanate and polyether polyol are polycondensed at a mass ratio of 1.
The sealant 4 in this application is disposed on the bonding surface on the top surface of the air duct groove 22 by using a dispensing device.
The polyurethane foaming glue is a product of cross combination of an aerosol technology and a polyurethane foam technology. The special polyurethane product is prepared by filling components such as a polyurethane prepolymer, a foaming agent, a catalyst and the like into a pressure-resistant aerosol can. When in use, a special dispensing tool is needed to say that the polyurethane foaming adhesive is arranged at a designated place.
The dispensing tool comprises a gun-separating type dispensing tool and a tube-type dispensing tool. The tube type product is mainly used as a disposable dispensing tool, the pressure of the tube type product is smaller than that of a gun type product, the tube type product can not be completely punched sometimes, phenomena such as a gambling valve cannot be punched easily and the like can be caused, in addition, a glue bubble hole punched by the tube type product is not fine and smooth in the gun type, and the expansion force is relatively large. When the material is sprayed out of the dispensing equipment, the foamed polyurethane material can expand rapidly and perform a curing reaction with air or moisture in a contacted matrix to form foam, namely polyurethane foaming glue. Utilize the point to glue instrument and set up the polyurethane foaming glue, can set up the polyurethane foaming glue in any place, can be in accordance with cold-stored wind channel 2 with the actual conditions in the gap between the cold-stored inside lining 6 sets up the polyurethane foaming glue in the place of needs, and the place that the gap is big can be glued many times.
The thickness of the sealant 4 after curing in this application is 2-3mm.
Because the glue has certain fluidity and needs a certain time to solidify, touch is avoided at the beginning of dispensing. After the glue is cured, a layer of film can be formed on the surface of the glue to prevent water, and the glue has certain elasticity and certain compression space. The thickness of the solidified sealant 4 is 2-3mm, and the thickness is too high, so that the structural stability of the refrigerating air duct 2 assembly of the whole refrigerator is reduced; the thickness is too low, the gap between the refrigerating air duct 2 and the refrigerating lining 6 can not be completely filled, and the air duct is not sealed enough.
Because the foaming glue has a certain after-foaming effect, the glue can be used for filling the gap by only filling 50% of the gap in the glue filling process, and the glue can slowly and automatically fill the gap in the curing process, so that the glue is saved, the expansion force is reduced, and the glue in the deep part of the gap can fully absorb moisture. If the thickness of the cured polyurethane foam is 2-3mm, the thickness of the cured polyurethane foam is slightly lower than that of the cured polyurethane foam.
When the polyurethane material is sprayed out of the dispensing tool, the foamed polyurethane material can expand rapidly and perform a curing reaction with air or moisture in a contacted matrix to form foam. The cured polyurethane foam has multiple effects of joint filling, bonding, sealing, heat insulation, sound absorption and the like.
