Abstract

The invention discloses a foaming basalt material used for high speed train and a manufacturing method. The foaming basalt material comprises foaming basalt plates, flame retardation PEF foam, foaming aluminium plates and decorative boards. The peripheral part of the foaming basalt plate is connected with the flame retardation PEF foam, the foaming aluminium plate is connected with the external surface of the flame retardation PEF foam, the decorative board is connected with the external surface of the foaming aluminium plate, and the foaming basalt plate and the flame retardation PEF foam are connected through gluing. The foaming aluminium plates are connected through a broken bridge structure, and the decorative board and the foaming aluminium plate are connected through gluing. The product is manufactured through basalt and the foaming aluminium plate by a foaming production technology, by using the characteristic of the flame retardation PEF foam and a hot pressing technology, the above materials are better combined, and the foaming basalt material has the advantages of water resistance, moisture resistance, fire resistance, durable and firm performances, convenient combination and installation, long usage life, certain buffer effect, no toxicity, no radiation, good thermal insulation performance, and stable chemical properties.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a foamed basalt material for high-speed trains and a production method. Background technique [0002] With the rapid development of railway traffic, the quality requirements for train interior parts are getting higher and higher. The quality of train interiors is primarily determined by their composite substrates. The traditional train inner plate composite base material mostly adopts solid wood board or PP wood powder board. Generally speaking, the wood utilization rate of solid wood boards is only 30% to 40%. Therefore, the disadvantage of using solid wood boards as composite substrates is that a large amount of logs will be used as raw materials, and the dependence on solid wood, a non-renewable resource, is relatively high. Strong; From the bending failure resistance of the train composite floor in the prior art, that is, the static bending strength and flexibility are rela...
