Description
Technical field
The invention belongs to railway cold chain technology field more particularly to a kind of refrigerator car roofs, foaming method and refrigerator car.
Background technique
The fresh and alive perishable goods of refrigerated railway car prevailing traffic, car body are equipped with thermal insulation layer and are kept the temperature, and thermal insulation layer is mainly filled out
Fill formula and two kinds of foaming type.Filled type thermal insulation layer is exactly the cavity shape for forming heat-insulating heat-preserving material according to inner panel and outside plate,
It is divided into fritter to be filled one by one, the main material of the heat-insulated material of filled type is polystyrene rigid foam.Foaming type is heat-insulated
Layer filling polyurethane foamed material, foamed material mainly in the cavity that inner panel and outside plate are formed are formed high by chemical reaction
Molecularly Imprinted Polymer, volume expansion fill entire cavity and form whole thermal insulation layer.
The heat-barrier material of filled type thermal insulation layer is to carry out the splicing of fritter scene according to insulating layer cavity size and shape, is existed
Splice gap, and the gap in all components cannot be filled, influences heat insulation.The polystyrene that filled type heat-barrier material uses
Rigid foam has water imbibition, and absorbs water and easily shrink, the fresh and alive perishable goods of refrigerator car prevailing traffic, air humidity between goods
Greatly, in vehicle with after a certain period of time, heat-barrier material water-absorbing shrinkable causes to assemble interstitial gap increasing, between some formation perforations
Gap forms heat bridge, seriously affects the heat-proof quality and air-tightness of cold chain equipment.Foamed material is fillable all in foaming type thermal insulation layer
Space forms a whole thermal insulation layer, and polyurethane foam does not absorb water, and it is good to can guarantee that thermal insulation layer has in the entire life cycle phase
Good thermal insulation and air-tightness.
Currently, both at home and abroad in technologically advanced cold chain equipment, the slab constructions such as side wall, headwall, flat-top be all made of foaming every
Heat structure is thermally shielded.And the refrigerator car with circular arc roof, because of roof structure complexity, volume is big, the foaming matter of foaming heat insulation
Amount it cannot be guaranteed that etc. composite factors, be all made of filled type heat insulation structural, the heat-insulated roof of filled type becomes the country because of poor thermal insulation property
The outer most important cold draining point of refrigerated railway car, seriously affects the synthesis heat-proof quality of refrigerated railway car.
In the implementation of the present invention, it is found by the applicant that in the prior art the prior art has at least the following problems:
It is limited by China railways limit, to increase interior volume, the roof of China railways refrigerator car is all made of dome knot
Structure.Because circular arc roof structure is unsatisfactory for integral foam, it is all made of polystyrene rigid foam and is filled, i.e., according to roof
Polystyrene rigid foam is imitated type and is cut into the live spelling of fritter progress by the cavity shape that outside plate and roof inner panel are formed
Dress., can not be completely closely connected using polystyrene rigid foam since there are errors for the manufacture of circular arc roof, there are clipping rooms
Gap, and polystyrene rigid foam has water-absorbing shrinkable characteristic, especially piece shrinks to form penetrating gap, reduce vehicle every
Therefore hot property and air-tightness need to improve the prior art.
