Preparation process for glass fibre reinforced plastic dual-layer oil storage tank

Abstract

The invention discloses a preparation process for a glass fibre reinforced plastic dual-layer oil storage tank. The preparation process comprises the following steps: preparing a pair of semicircular cylinder moulds, splicing the semicircular cylinder moulds into a circular cylinder mould, preparing hemispherical sealing head moulds, respectively performing raw material spraying on the circular cylinder mould and the hemispherical sealing head moulds, then performing heating curing treatment, disassembling the circular cylinder mould into the semicircular cylinder moulds, taking out an intermediate cylinder body, butting the intermediate cylinder body and the pair of semicircular cylinder moulds to install an oil storage tank blank, forming a plurality of well mouths in the oil storage tank blank, and installing operating well walls and electronic systems. The intermediate cylinder body is prepared in the mode of performing spraying moulding on the circular cylinder mould which is spliced by the semicircular cylinder moulds, so that the processes of spraying and de-moulding can be performed highly effectively; the preparation process complexity is greatly reduced; meanwhile, butting openings of the oil storage tank blank are transferred out of the intermediate cylinder body from the intermediate cylinder body, so that the butting openings avoid a stress concentration area; the oil storage tank cannot crack easily to cause the situations of oil leakage and liquid leakage, so that the reliability of a finished product is improved.

Description

technical field [0001] The invention relates to the technical field of oil storage equipment, and more specifically, relates to a preparation process of a glass fiber reinforced plastic double-layer oil storage tank. Background technique [0002] At present, in the preparation process of resin glass fiber reinforced plastic oil storage tanks, the preparation process of glass fiber reinforced plastic tanks generally adopts the spray molding process, which requires it to have a spray forming mold first. [0003] The traditional mold consists of two parts, the left mold formed by half of the middle half tank body and hemispherical head, and the right mold formed by the other half of the middle half tank body and hemispherical head. Barrel-shaped structure, mold manufacturing is more complicated, and the injection molding process is also more complicated to operate. At the same time, when the half-tanks spray-molded by the left mold and the right mold are connected, the butt joi...
