The invention relates to a high-barrier composite hose which comprises a hose body, a hose shoulder and a cap cover, wherein a hose wall of the hose body is provided with a barrier layer; the barrier layer is a PVA (Polyvinylalcohol) coating; preferably, the hose wall of the hose further comprises a printing layer, an outer adhesive layer, an inner adhesive layer and a heat sealing layer; the printing layer, the outer adhesive layer, the barrier layer, the inner adhesive layer and the heat sealing layer are sequentially bonded from the outside in; the hose wall of the hose body further comprises an oil ink layer; the oil ink layer is positioned between the printing layer and the outer adhesive layer and bonded with the printing layer and the outer adhesive layer respectively, or is positioned outside the printing layer and bonded with the printing layer; the hose shoulder is mounted on the hose body; and the cap cover is arranged on a hose orifice of the hose shoulder in a covering manner. The invention further relates to a manufacturing method of the high-barrier composite hose. The high-barrier composite hose is high in barrier property, convenient to process, low in production cost, and suitable for large-scale popularization and application, and the barrier property is improved comprehensively.
Description
technical field [0001] The invention relates to the field of pipes, in particular to the field of composite hoses, in particular to a high-barrier composite hose and a manufacturing method thereof. Background technique [0002] With the continuous development of material science, plastic macromolecules have been widely used in all aspects of social production. In the field of pipe materials, plastic pipes play an extremely important role in the packaging fields of modern cosmetics, food, and medicine because of their high barrier properties to water vapor and air, safety, hygiene and non-toxicity. [0003] Most of the barrier layers used in the production of plastic pipes in China are EVOH. The production of ordinary EVOH co-extrusion PE film requires a large-scale multi-layer co-extrusion line, which requires high production conditions, and EVOH itself is expensive. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned...
