Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of curtain coating shaping system of radiation refrigeration equipment for making film is present embodiments provided, it is uniform for producing thickness
Radiation refrigeration film, including the extruder 2 for squeezing out high-temperature fusant, the die head 3 for being initially formed, be used for high-temperature shaping
The first casting roller 4, for the second low-temperature shaped casting roller 5 and for low-temperature shaped third casting roller 6, the mould
First 3 are located at 2 left side of extruder, and first casting roller 4 is located at 3 lower left side of die head, and second casting roller 5 is located at the first curtain coating
4 left side of roller, the third casting roller 6 are located at 5 left side of the second casting roller；1 first end of radiation refrigeration film is located under die head 3
Side, 1 second end of radiation refrigeration film from right to left successively with 4 bottom of the first casting roller, the top of the second casting roller 5 and the
Three casting rollers, 6 bottom is tangent.
As shown in Figure 1, in the present embodiment, by including but not limited to Ag, TiO2, ZnS, graphene, glass microballoon, Al, nitrogen
Change gallium, carbon nanotube are mixed with including but not limited to TPX, PET, PETG, PMMA, PVDF, ABS, EVOH, EVA high molecular material,
