Vehicular roof environment-friendly high-flame-retardance foam material and preparation method thereof

Abstract

The invention discloses a roof environment-friendly high-flame-retardance foam material for multi-purpose vehicles and a preparation method thereof. The foam material is composed of, by mass, isocyanate and a combined material according to a proportion of 1:1.65, and the combined material is composed of, by mass, 16-20 parts of polyester 10100, 55-58 parts of polyester 3360, 45-55 parts of reinforced glass fiber, 3.0-3.5 parts of silicon oil AK8860, 8-10 parts of triethanolamine, 1.2-1.7 parts of catalyst HP-54, 1.6-1.9 parts of catalyst HP-80, 3.0-3.8 parts of water and 40-45 parts of flame retardant TCEP. After adopting the materials and the method, the foam material is high in flame retardance and less prone to burning when catching fire, so that fireproof safety and personal safety of whole vehicles are ensured. In addition, a vehicular roof made by adopting the material is quite light in weight and can meet weight requirements of vehicles; raw materials of the foam material are environment-friendly and reasonable in matching, so that the foam material does not release substances toxic and harmful to human body.

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 foaming material for a commercial vehicle ceiling and a preparation method thereof. Background technique [0002] With the development of the automobile industry, the car roof is an important part of the car, and its fire safety is very important. In addition to the fire safety, the existing car roof also needs to have lightweight requirements to adapt to the vehicle. The overall weight requirement, in order to achieve this purpose, people try various materials as the material of the car roof, but the pursuit of light weight also reduces the safety, and it is often easy to cause fires when encountering failures or accidents Therefore, how to meet the demand for lightweight and have flame-retardant performance to ensure safety is a difficult technical problem to solve. In addition, the existing roof materials for ...
