Description
Technical Field
The invention relates to the technical field of PVB (polyvinyl butyral) film production, in particular to a device and a process for producing an ultra-wide automobile colored tape and a gradual change PVB film.
Background
Along with the improvement of the living standard of people, the market of household cars is getting bigger and bigger, and due to the special performance of the PVB membrane, the laminated glass has the special performances of excellent optical performance, penetration resistance, sound insulation, heat insulation, ultraviolet insulation, high and low temperature climate resistance, excellent safety performance and the like, so that the front windshield glass and the side windshield glass of the automobile both use the laminated glass, and the consumption of the PVB membrane is rapidly increased. At present, the integration of the front windshield and the skylight in the market tends to require that the width of the colored ribbon reaches more than 600mm, and at present, no manufacturers exist for the wide colored ribbon with the width of more than 600mm in China.
The special car diaphragm market demand of present PVB super wide colored ribbon is huge, but current PVB diaphragm apparatus for producing adopts PVB resin and pigment to mix in advance more, then flows the curtain coating film behind the extruder jointly, can only produce the narrower PVB diaphragm of colored ribbon width, also can't produce the PVB diaphragm of gradual change of color.
Patent CN2013208155730 discloses a colored PVB's colouring and drying device, including the colouring case that arranges in proper order, turn to the roller, wash tank and cooler bin, the PVB intermediate coat that will come out from the die head gets into the colouring case that contains dye solution and colors, can let the PVB diaphragm cool down simultaneously, then the PVB intermediate coat gets into the wash tank after turning to the roller, wash the solution on diaphragm surface in the cooling water, and make the temperature of diaphragm further reduce, the PVB diaphragm that comes out from the wash tank gets into the drying roller after turning to the roller and carries out the predrying, it is further dry to get into the drying cabinet again. The device need make the PVB diaphragm earlier, then carries out further dyeing drying to the PVB membrane again, and the operation is more loaded down with trivial details, and can't produce the PVB diaphragm of gradual change colour.
In patent CN2012205559371, a colorant distributor for a color PVB film insert is disclosed, which comprises an insert, wherein a colorant channel is arranged in the insert, and the colorant channel is spaced from the edge of the insert, i.e. the colorant channel is slightly away from the edge of the insert, preferably 1 cm. Stopping the operation of colored ribbon PVB film, changing into the transparent PVB film of production after, injecting into the mould as transparent PVB raw materials, extrude through short-term promotion, can thoroughly, cleanly extrude the colouring material of remaining in the mould to ensure the production and the quality of the transparent PVB film in later stage. Through the pigment distributor that adopts the colored PVB film of this kind of structure to insert for the PVB production line can not only produce the colored ribbon PVB film, can also produce transparent PVB film, make full use of production resource. However, the color material distributor can only produce PVB films with the width of 300mm and 300mm, and cannot produce color tapes with the width of more than 600 mm.
