Storage and transport gas cylinder with fiber wound plastic liner, and manufacturing method thereof

Abstract

The invention discloses a storage and transport gas cylinder with a fiber wound plastic liner. The storage and transport gas cylinder comprises a plastic liner, a fiber-reinforced layer and a fiber reticular bonding layer, and the fiber reticular bonding layer is fused into the plastic liner; the fiber-reinforced layer is wound the exposed part of the fiber reticular bonding layer and the outer wall of the plastic liner; and resins are filled among the fiber-reinforced layer, the fiber reticular bonding layer and the outer wall of the plastic liner. The invention further discloses a manufacturing method of the gas cylinder, and the manufacturing method comprises the steps that fiber mesh cloth is prearranged in a plastic liner die, and plastic particles are heated so that the plastic particles are fused and extruded into a semi-fluid baggy semi-finished product; air is blown into the semi-finished product for manufacturing the plastic liner, and the fiber mesh cloth is hot fused into the wall of the plastic liner so that the fiber reticular bonding layer is formed; and fiber bundles are socked with the resins and wound on the fiber reticular bonding layer so that the fiber-reinforced layer is formed. According to the storage and transport gas cylinder, the problem of bonding between the plastic liner and the fiber winding layer can be solved effectively, and the debonding phenomenon is not generated after vacuum circulating detection and when temperature, pressure and other environmental conditions are changed greatly.

Description

technical field [0001] The invention relates to a high-pressure gas storage bottle, which belongs to the technical field of pressure vessels, in particular to a fiber-wound plastic liner gas storage bottle and a manufacturing method thereof. Background technique [0002] With the continuous progress of new energy technology, the corresponding energy storage and transportation technology has also made great progress in recent years. The demand for pressure gas cylinders containing energy media, especially gas media, has also increased significantly at home and abroad. However, the current domestic market application The vast majority of gas cylinders used for high-pressure gas storage and transportation are all-metal or fiber-wound reinforced gas cylinders with metal liners. However, steel cylinders have defects such as complex molding process, high quality, inconvenient transportation, easy corrosion, no visibility, and frequent explosion accidents during use.

AI Technical Summary

Problems solved by technology

The second option is to apply polyurethane and other adhesives on the outer wall of the plastic liner to bond the liner and the fiber winding layer together. Since the two materials are different and cannot be intimately combined, this method still cannot meet the detection conditions

So up to now, the key problem of the combination of the plastic liner and the fiber winding layer interface has not been effectively solved
