Abstract

The invention discloses an environmentally-friendly high-flame-retardant composite material used for an air-conditioned bus tube wall, the composite material comprises a combined material and isocyanate, the mass ratio of the combined material: isocyanate is 1.6: 1, 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 high flame-retardant vehicle roof composite material and a preparation method thereof. Background technique [0002] The pipe walls of air-conditioned vehicles in the prior art are usually plastic products, but plastic products usually have poor flame retardancy, and are prone to fires in the event of failures or accidents, thereby causing serious loss of life and property. During the transportation of automobiles, due to electrical short circuit, engine failure, traffic accidents and other reasons, it is very easy to cause fire, resulting in property loss and casualties. And flammable car interior decorations tend to aggravate the degree of fire in accidents. Moreover, the sources of raw materials for many car interiors are not environmentally friendly, and some toxic and harmful substances are often volatilized. People will inhale...
