Dual-layer oil tank made of glass fiber, manufacturing method thereof and special mold

Abstract

The invention discloses a dual-layer oil tank made of glass fiber, a manufacturing method thereof and a special mold. The dual-layer oil tank comprises a storage inner tank I made of glass fiber and a reinforcing tank II stuck to the outer surface of the storage inner tank made of glass fiber. A glass fiber sleeve adopted as a reinforcing rib concurrently is further stuck between the storage inner tank I made of glass fiber and the reinforcing tank II. First glass fiber non-twist fine mesh gauze capable of solidifying resin, a first S yarn picking layer, a first glass fiber short fiber layer, a first Z yarn picking layer, first glass fiber plying coarse mesh gauze and an anticorrosion solidification layer are sequentially stuck into the storage inner tank I from interior to exterior in a soaking mode. Second glass fiber plying coarse mesh gauze capable of solidifying resin, a second Z yarn picking layer, a second glass fiber short fiber layer, a second S yarn picking layer, second glass fiber non-twist fine mesh gauze, a modification polyethylene layer and an anti-aging white oil layer are sequentially stuck into the reinforcing tank II from interior to exterior in a soaking mode. The dual-layer oil tank achieves the effects of being high in safety and environment-friendly performance, low in cost and capable of preventing steam corrosion 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...
