Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing:
[0016] see figure 1 , the present invention provides a PVB film with a rainbow effect, which is formed by five-layer co-extrusion, wherein the outer first layer 11 and the fifth layer 15 are transparent layers, the middle second layer 22, the third layer 23, the second layer Four layers 24 are color layers; any one or more layers of the color layers form a rainbow pattern.
[0017] Further, the second layer 22 , the third layer 23 , and the fourth layer 24 in the color layers of the present invention are arranged randomly in three colors of red, green, and blue to form a rainbow pattern.
[0018] The layer thicknesses of the second layer 22, the third layer 23, and the fourth layer 24 in the intermediate color layer are 60-340 μm.
[0019] Each layer of the color layer is trapezoidal, and the long sides and short sides of two adjacent layers are connected.
[0020] The p...

Abstract
The invention discloses a PVB film with a rainbow effect. The PVB film is formed by a manner of co-extrusion of five layers, wherein a first layer and a fifth layer, on the surface of the PVB film, are transparent layers; a second layer, a third layer and a fourth layer, in the middle of the PVB film, are colored layers; and a rainbow pattern is formed by any one or more of the colored layers. The invention further discloses a manufacturing method of the PVB film with the rainbow effect. According to the PVB film and the manufacturing method thereof disclosed by the invention, the colorful effect and the transition gradient color effect are realized through the combination of three colors in different concentration percentages by utilizing the light transmission of the PVB film and the color matching principle of three-primary colors, so that a rainbow color changing effect is achieved, the problem that in the prior art the colored pattern of the PVB film is relatively single is effectively solved, and the colorful PVB film with the rainbow pattern is realized.
Description
technical field [0001] The invention belongs to the technical field of PVB film production, and in particular relates to a PVB film with rainbow effect and a manufacturing method thereof. Background technique [0002] PVB film can be used to make laminated glass as a main safe decorative material, mainly used in curtain walls, skylights, roofs, partitions, safety and anti-theft doors and windows, and commodity display windows of high-rise buildings such as commercial buildings, hotels, and restaurants. However, the PVB laminated glass products on the market are relatively single in color and pattern, and there are only single-color PVB film products on the market. It is difficult to adapt to the diverse needs of doors, windows and architectural glass in color patterns. The colorful films disclosed in the prior art are generally realized by using the principle of light wave reflection or by color printing. There is only single-color diaphragm technology on PVB material diap...
