Abstract

The invention discloses an environmentally-friendly high-flame-retardant composite material used for a high-speed train air-conditioning duct, the composite material comprises a combined material and isocyanate, the mass ratio of the combined material: isocyanate is 1: 1.7, the composite material has high flame retardant properties, and is not easy to burn when meeting a fire, thus ensuring the safety of the whole vehicle and the safety of passengers, the composite material has the advantages of deformation resistance, even if the composite material is used for a long term, the composite material may not deform, and raw materials used in the composite material are environmentally friendly, so that no substances toxic and harmful to the human body may be released.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to an environment-friendly and highly flame-retardant composite material for air-conditioning ducts of high-speed trains. Background technique [0002] In recent years, with the continuous development of economy and technology and the improvement of people's living standards, people have higher and higher requirements for ride comfort when traveling, especially the improvement of the smell inside the car. However, general-purpose materials cannot meet the odor improvement requirements or cannot meet the installation requirements and flame retardancy requirements, which requires researchers to continuously explore new materials. [0003] At present, the air duct sealing materials commonly used in the bus industry on the market are mainly divided into two categories: the first category is thermosetting composite materials, such as glass fiber reinforced unsatura...
