Abstract

The invention discloses flame-retardant automotive interior composite fabric and a preparation method thereof. The flame-retardant automotive interior composite fabric comprises flame-retardant automotive interior fabric and flame-retardant soft polyurethane foam sponge which are compounded through flame compounding, wherein the back surface of the flame-retardant automotive interior fabric contains a flame-retardant coating adhesive functional material. The flame-retardant automotive interior composite fabric has the characteristics of environment friendliness, low smoke, low toxicity, low VOC, a low fogging value, no peculiar smell, a soft hand feel, excellent flame resistance, high peel strength, good resilience, good antistatic performance and the like, and can be widely applied to seats, safety seats, roofs, door panels and handrails of cars or buses.

Description

technical field [0001] The invention relates to the field of flame-retardant materials, in particular to a flame-retardant automotive interior composite fabric and a preparation method thereof. Background technique [0002] In recent years, automobile combustion safety accidents have occurred frequently. Relevant national ministries and commissions issued a document pointing out that the combustion test standards for automobile interior materials are one of the important factors to ensure automobile safety. All countries have clear regulations on the flammability of automotive interior fabrics. my country has proposed new standards for the flame retardant performance of school bus, passenger car and train interior fabrics. The horizontal combustion test index is changed from the original burning speed ≤ 100mm / min Reduced to ≤70mm / min. The flame retardant requirements of passenger car interior materials only refer to the national mandatory GB8410-2006 to control the horizonta...
