Abstract

The invention discloses an environment-friendly anti-flaming fabric compound for motor vehicle interior and a preparation method thereof. The environment-friendly anti-flaming fabric compound for motor vehicle interior comprises an environment-friendly anti-flaming fabric and an anti-flaming lining for motor vehicle interior, which are tightly combined with each other through flame compounding, anti-flaming glue compounding or anti-flaming hot molten glue compounding. The environment-friendly anti-flaming fabric for motor vehicle interior has the characteristics of dry fabric surface, environmental protection, low smoke, less toxicity, low VOC, low atomizing value, no odor, soft hand feel, excellent anti-flaming property, high peeling strength, high resilience, excellent antistatic property, and the like, and can be widely applied to the seats of cars, coaches, trucks, high speed rails, bullet trains, urban railways, low-speed trains, safety seats, ceilings, door planks, handrails, andthe like.

Description

Technical field [0001] The invention relates to the field of flame-retardant materials, in particular to an environmentally-friendly flame-retardant fabric composite for motor vehicle interior decoration and a preparation method thereof. Background technique [0002] In recent years, motor vehicle combustion accidents have occurred frequently, and relevant national ministries and commissions have issued documents stating that the combustion test standard for motor vehicle interior materials is one of the important factors to ensure motor vehicle safety. Various countries have clear regulations on the flammability of interior fabrics for vehicles. my country has proposed new standards for the flame retardant performance requirements of interior fabrics for school buses, buses and trains. The horizontal combustion test index is changed from the original burning speed ≤100mm / min is reduced to ≤70mm / min. The flame retardant requirements of passenger car interior materials only refer...
