The invention discloses a preparation technology of a
composite material tank car, and belongs to the technical field of transportation tank car preparation, the preparation technology comprises preparation of an inner
core shell, winding forming of a winding layer, installation of a supporting structure and installation of a platform structure; the preparation of the inner
core shell comprises the steps of preparation of an upper inner
core shell and a lower inner core shell, preparation of a wave-proof plate, overturning and standing of the upper inner core shell and the lower inner core shell, co-cementing curing of the lower inner core shell and the wave-proof plate,
assembly of the upper inner core shell and the lower inner core shell, co-cementing curing of the upper inner core shell and the wave-proof plate and sealing curing of a center joint. The inner core upper shell and the inner core lower shell which are formed by the male mold are hoisted and stood by the shell hoisting tool device and the
standing frame, and then the inner core assembling tool is used for assembling the inner core upper shell, the inner core lower shell and the washboard, so that the method can be suitable for preparing a tank car from a
composite material. According to the tank body prepared from the
composite material, diversity of transportation media can be achieved, the problem that a
metal tank body is not universal in acid and alkali is solved, and the service life can be prolonged.
