Microstructural multi-layer composite distributor

Abstract

The invention discloses a microstructural multi-layer composite distributor, which comprises a microlayer distributor and a hybrid amplifier, wherein the microlayer distributor is formed by overlapping one or more structural plates; the structural plate is provided with a plurality of flow layer communicating ports at intervals; after a plurality of layers of structural plates are overlapped, corresponding flow layer communicating ports of the layers are communicated; a feed melt is injected from runners of the structural plates, is distributed by the flow layer communicating ports of the layers to be superposed, and is transmitted to the hybrid amplifier; the hybrid amplifier is provided with a plurality of flow layer channels which are overlapped in a staggered mode and form a hybrid outlet channel; and the flow layers are multiplied and overlapped at the hybrid outlet to form an integral flow layer. The ideal thickness of the flow layer is achieved through compression, the layer number of the structural plates can be increased so as to achieve the overlapping and multiplication of more layers, and various rays are reflected through interference of the surfaces of the hundreds of flow layers, so that a composite membrane has a rainbow effect.

Description

technical field

[0001] The invention relates to a multi-layer composite dispenser applied in the field of composite film and sheet material co-extrusion production. Background technique

[0002] Composite films and sheets, especially multi-layer composite films, currently on the market, the composite dispensers of such products are usually single-layer or less than nine-layer structures. Technically speaking, the more layers, the lower the possibility of fracture due to the dissolution density of the film. The products produced by low-layer fat-dissolving polymers do not have strong flexibility. Although the product surface is relatively flat, due to The quality has no toughness at all, so the product is easy to break, and the finish is not satisfactory. For some decorative materials with relatively high color requirements, it is even less able to achieve the effect of various interlaced colors required by some consumers. The multi-layer composite distributor is the most i...
