Double-sided polyurethane high-pressure wear-resistant composite hose and machining process thereof

Abstract

The invention discloses a double-sided polyurethane high-pressure wear-resistant composite hose. The hose comprises a hose body which comprises an inner waterproof layer and an outer wear-resistant layer, wherein a first enhancement layer and a second enhancement layer are additionally arranged between the wear-resistant layer and the waterproof layer, a first adhesive layer is additionally arranged between the wear-resistant layer and the first enhancement layer, a second adhesive layer is additionally arranged between the first enhancement layer and the second enhancement layer, and a third adhesive layer is additionally arranged between the second enhancement layer and the waterproof layer. The hose disclosed by the invention has the advantages that by combining the first enhancement layer and the second enhancement, the wear resistance and the corrosion resistance of the hose are enhanced; the waterproof layer, the wear-resistant layer, the first enhancement layer and the second enhancement layer are separated through the adhesive layers, so that the wear resistance of the hose is enhanced, and the layers are firmly adhered and are unlikely to split, and therefore, the service life of the hose is prolonged.

Description

technical field [0001] The invention belongs to the field of pipe materials, relates to the field of composite hose materials, in particular to a double-sided polyurethane high-pressure wear-resistant composite hose, and also relates to a double-sided polyurethane high-pressure wear-resistant composite hose and its processing technology. Background technique [0002] Composite hose is a special packaging container, which occupies an important position in the field of packaging. The composite hose is made of a variety of materials with a multi-layer sealing structure, and it still has good crack resistance and leakage resistance in harsh environments. Sex, will not burst out suddenly. However, in the existing composite hose, the composite hose is woven with polyester staple fiber or polyester industrial filament, and the inner lining is made of rubber or polyurethane, which cannot have both wear resistance and corrosion resistance. It is inconvenient, but in the past process...

Problems solved by technology

However, in the existing composite hose, the composite hose is woven with polyester staple fiber or polyester industrial filament, and the inner lining is made of rubber or polyurethane, which cannot have both wear resistance and corrosion resistance. It is inconvenient, but in the past processing technology of composite hose, the process is simple, just penetrate the lining into the reinforcement layer, and thermally vulcanize the lining and reinforcement layer, resulting in a thin and thin composite hose wall. Disadvantages of pressure resistance and non-wear resistance
