Non-metal flame-retardant lining block structure for railway tank car and preparation method thereof

Abstract

The invention discloses a non-metal flame-retardant lining block for a railway tank car; a non-metal flame-retardant lining block structure for the railway tank car comprises a first lining block located right under an oil tank, a second lining block located right under the oil tank and a third lining block located under a side of the oil tank, and the lining block comprises an arc-shaped contactsurface and is fixed on a train chassis through screw holes and screws. The non-metal flame-retardant lining block for the railway tank car is prepared by the following steps: melting a specially-madehigh polymer material; adding flame retardants and ceramic powder in different parts respectively; physical blending said materials through a mechanical method to form mixed materials of flame retardants and ceramic powder with different contents; respectively injecting the mixed materials into a mold in an injection molding machine, enabling the flame retardants and the ceramic materials to mainly distribute on the surface of the lining block, and forming different content distributions of reinforcing materials at different positions; or heating and melting in an extruder to continuously extrude a polymer melt from a mouth mold and cooling the polymer melt to obtain special plates with different components, and carrying out corresponding subsequent machining on the plates to obtain the structure.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a non-metal flame-retardant lining block structure for a railway tank car and a preparation method thereof. Background technique [0002] Oil storage tank, referred to as oil tank or storage tank, is a container for storing crude oil or other petroleum products. In modern industrial production, in order to transport large quantities of crude oil at one time and reduce transportation and production costs, railways are usually used for oil transportation. The current transportation method is to fix the oil tank on the train chassis, and then use the train for transportation. During the transportation process, due to the large mass of the oil tank, the inertia of the train is very large when braking and starting. Damping parts are arranged between them to prevent the impact of the inertia on the oil tank when the train starts and stops. At present, the damping parts ...

Problems solved by technology

Due to the high temperature weather that often occurs during railway transportation, the wooden shock-absorbing parts are very dry. At the same time, it is inevitable that some metal parts will rub against each other to generate static electricity or collide with sparks during the operation of the train. Therefore, in some extreme cases, It may cause the burning of the wooden shock absorbing parts, which may lead to the explosion accident of the oil tank
