Abstract

The invention discloses an environmentally friendly flame-retardant fabric compound for motor vehicle interior decoration and a preparation method thereof, comprising a motor vehicle interior environment-friendly flame-retardant fabric and a flame-retardant lining, the two are compounded by flame, flame-retardant glue or flame-retardant heat Melt-adhesive compounding achieves tight bonding. The environmentally friendly flame-retardant composite fabric for motor vehicle interiors has dry cloth surface, green environmental protection, low smoke and less toxicity, low VOC, low atomization value, no peculiar smell, soft hand feeling, excellent flame-retardant performance, high peel strength, good resilience, Good antistatic performance and other characteristics, can be widely used in seats, safety seats, ceilings, door panels, handrails, etc.

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. Relevant national ministries and commissions issued a document pointing out that the combustion test standard of motor vehicle interior materials is one of the important factors to ensure the safety of motor vehicles. All countries have clear regulations on the flammability of automotive interior fabrics. my country has proposed new standards on the flame retardant performance requirements of school bus, passenger car and train interior fabrics. 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 r...
