A kind of preparation method of lightweight and environment-friendly high-speed train plug door cover plate

Abstract

The invention relates to the technical field of track traffic, and discloses a lightweight environmental protective high speed train sliding plug door cover plate and preparation method. The lightweight environmental protective high speed train sliding plug door cover plate comprises a left door cover plate, a right door cover plate and a top door cover plate connected to the tops of the left doorcover plate and the right door cover plate in a crossing mode, wherein the left door cover plate, the right door cover plate and the top door cover plate are formed by mold pressing hemp fiber composite plates, and the back surfaces of the left door cover plate, the right door cover plate and the top door cover plate are connected with metal reinforcing ribs correspondingly; and the mold pressinghemp fiber composite plates comprise front surface layers, middle layers and back surface layers, the front surface layers, the middle layers and the back surface layers are sequentially connected inan overlapping mode, the middle layers are hemp fiber felt layers prepared from synthetic fabrics of the hemp fiber and polypropylene fiber, and the front surface layers and the back surface layers are both non-woven fabrics. According to the lightweight environmental protective high speed train sliding plug door cover plate and the preparation method, lightweight of the high speed train slidingplug door cover plate is achieved, and environmental protective performance of the sliding plug door cover plate is further improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a light-weight and environment-friendly high-speed train plug door cover and a preparation method. Background technique [0002] At present, interior panel components such as plug door panels used in high-speed rail transit trains are made of glass fiber reinforced plastics. Ribs and fixed with bolts or screws. [0003] There are the following problems in the above-mentioned sliding door cover plate made of glass fiber reinforced plastic base material: [0004] One is poor environmental protection. FRP is formed by the reaction of unsaturated resin and methyl ethyl ketone peroxide. During the reaction, a large amount of aldehyde and ketone gases harmful to the human body will be produced, and the debris formed by the broken glass fiber cannot be decomposed after entering the human body, which will cause harm to human health. Harm; moreover, the FRP material itself cannot ...

AI Technical Summary

Problems solved by technology

[0004] One is poor environmental protection

FRP is formed by the reaction of unsaturated resin and methyl ethyl ketone peroxide. During the reaction, a large amount of aldehyde and ketone gases harmful to the human body will be produced, and the debris formed by the broken glass fiber cannot be decomposed after entering the human body, which will cause harm to human health. hazard; moreover, the FRP material itself cannot be degraded and will eventually become waste that damages the environment

[0005] Second, the lightweight effect is poor

Therefore, the weight of the sliding door cover plate made of glass fiber reinforced plastic base material is relatively heavy, thereby increasing the overall weight of the train, and the increase of the overall weight of the train will cause the energy consumption of the train under high-speed operation
