Problems solved by technology
The invention provides a distributor structure for preparing multiple layers of CPP thin films. According to the distributor structure for preparing the multiple layers of CPP thin films, the problemsthat the flow dividing technology of an existing distributor is uneven, especially when the thickness of a single CPP film layer is lower than 15 [mu]m or below, even distributing is difficult to achieve, and consequently, co-extrusion of the multiple CPP film layers is difficult to achieve are solved. The distributor structure adopts the mode that multiple sprue spreaders are adopted for flow dividing, then converging is conducted again, thus olypropylene melt liquid can be evenly distributed through the distributor structure, and the thickness of each layer of CPP thin film can reach 5 [mu]m-15 [mu]m; and in this way, the original single layer of CPP thin film can be replaced with the multiple layers of CPP thin films, and meanwhile, the material cost is not increased.
