Glass fiber reinforced plastics twin-wall oil tank, preparation method and special mould thereof

Abstract

The invention belongs to the technical field of glass fiber reinforced plastics container and in particular relates to a glass fiber reinforced plastics oil tank and a preparation method thereof. The major technical proposal includes a full length revolving shaft started by an actuating unit. At least two barrel-type moulds are sleeved on the revolving shaft, the barrel-type moulds are composed of structures with frustum-shaped column casings and end parts, frustum openings of one barrel-type mould are sleeved on the revolving shaft and the frustum openings of other barrel-type moulds are respectively penetrated and sleeved on the column casing of the prior barrel-type mould in sequence, and the other ends of the barrel-type moulds and the revolving shaft are respectively and relatively fixed. The integrated and jointless glass fiber reinforced plastics twin-wall oil tank can be directly produced by the glass fiber reinforced plastics twin-wall oil tank and the preparation method of the invention and the defect of inconsistent pressure-bearing property and easy leakage of the manually pasted reducer glass fiber reinforced plastic pipe is overcome. With the mould of the invention, the reducer glass fiber reinforced plastic pipes of different specifications can be prepared, the use ratio of the mould is greatly improved and the production cost is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic containers, and in particular relates to a glass fiber reinforced plastic double-wall oil storage tank, a preparation method thereof and a special mold. Background technique [0002] With the rapid development of industrial economy, the demand for oil storage tanks is increasing and its capacity is required to be larger and larger. Therefore, the problems of corrosion resistance and safety of oil storage tanks are becoming increasingly prominent. At present, whether it is a large-scale oil storage tank buried in the ground or an oil storage tank matched to a tanker truck, there are two types of structures: one is a steel oil storage tank formed by welding steel plates, and the other is a steel oil storage tank made of the above-mentioned steel The outer surface of the oil storage tank is coated with a layer of composite structure made of glass fiber reinforced plastics. The...

AI Technical Summary

Problems solved by technology

The steel oil of the first type of structure has extremely poor corrosion resistance and short service life, which easily causes environmental pollution problems; the second type of composite structure oil storage tank is difficult to integrate with steel plate and glass fiber reinforced plastic. It is very easy to have two skins between the two, which makes it difficult for the FRP layer wrapped outside the steel tank to realize its anti-corrosion function, and the oil storage tank with this structure also has problems such as short service life.
