Nano fireproof insulating thermal-insulating macromolecule material for high-speed rail vehicle body

Abstract

The invention discloses a nano fireproof insulating thermal-insulating macromolecule material for a high-speed rail vehicle body. The material comprises a fireproof coating consisting of a matrix resin, a catalyst, a carbonization agent and a foaming agent, and further comprises the following material components: nano aluminum hydroxide, nano silicon dioxide, a plasticizer, a reinforcing fiber, anantioxidant, graphite and film formation aids. Due to addition of the nano aluminum hydroxide in the fireproof coating, the fireproof coating has good fireproof performance and is small in amount andlow in cost, the physical-chemical mechanical properties and the weather resistance can be greatly improved, when being combusted, a fireproof coating layer is expanded, a foaming layer is very highin density, then a uniform fireproof thermal-insulating layer is formed, and effective fireproof protection can be provided for the high-speed rail vehicle body.

Description

technical field [0001] The invention relates to the technical field of functional composite materials, in particular to a nanometer fire-proof and heat-insulating polymer material used for high-speed rail car bodies. Background technique [0002] High-speed rail refers to a railway with a high design speed standard for basic settings and a safe and high-speed train running on the track. The operating speed of the train is 200km / h. Because the high-speed rail body operates at a high speed, the requirements for the materials used in the high-speed rail body are very high. , the requirements for fire insulation and heat insulation are also very high. If the fire insulation and heat insulation of the car body material is not strong, after the car body catches fire, its running speed will be faster, which will accelerate the burning of the car body, and the occupants will not be able to evacuate in time, causing casualties. Therefore, there is an urgent need to provide a nano-fir...
