A double-layer oil tank made of glass fiber and its preparation method and special mold

Abstract

The invention discloses a double-layer oil tank made of glass fiber, its preparation method and a special mold. It includes an inner storage tank I made of fiberglass and a reinforced tank II bonded to the outer surface of the inner storage tank made of glass fiber. The glass fiber inner storage tank I and the reinforced tank II are also bonded with a glass fiber casing that also serves as a reinforcing rib. The glass fiber inner storage tank I is impregnated with possible fibers from the inside to the outside. The first fiberglass untwisted roving cloth, the first S-twisted yarn layer, the first glass fiber short fiber layer, the first Z-twisted yarn layer, the first glass fiber plied roving cloth and the anti-corrosion curing layer of the cured resin are bonded in sequence. ; The reinforced tank II passes through the second glass fiber plied roving, the second Z-twisted yarn layer, the second glass fiber short fiber layer, and the second S-twisted yarn impregnated with curable resin from the inside to the outside. The thread layer, the second fiberglass untwisted gauze cloth, the modified polyethylene layer and the anti-aging white oil layer are bonded in sequence; achieving high safety, high environmental performance, low cost, and the ability to prevent water vapor erosion and electrolytic corrosion.

Description

technical field [0001] The invention relates to a double-layer oil tank, in particular to a double-layer oil tank made of glass fiber, its preparation method and a special mold. Background technique [0002] With the rapid development of industrial economy, the demand for storage oil tanks is increasing, and its volume is getting larger and larger. The current oil tanks are buried underground all the year round, and are vulnerable to erosion and electrolytic corrosion of underground water vapor, which not only brings The direct loss of incoming oil products can also cause environmental pollution. Contents of the invention [0003] The first object of the present invention is to provide a glass fiber double-layer oil tank with high safety, high environmental protection performance, low cost, and capable of preventing water vapor erosion and electrolytic corrosion. [0004] In order to achieve the above object, the technical solution of the present invention is a double-lay...
