Abstract

The invention discloses a flame-retardant PVC leather compound for traffic interior decoration as well as a preparation method and application thereof. The PVC leather compound comprises a PVC leatherlayer, a flame-retardant functional layer and an elastic layer, wherein the flame-retardant functional layer is prepared from 100 parts of PVC paste resin, 50-120 parts of a flame-retardant plasticizer, 5-20 parts of a phosphorus-containing liquid flame retardant, 5-20 parts of a powder flame retardant, 3-10 parts of a flame-retardant synergist, 1-10 parts of zirconium phosphate, 1-5 parts of anantioxidant, 1-5 parts of a heat stabilizer, 1-10 parts of a filler, 0-5 parts of color paste and 1-10 parts of a foaming agent; the elastic layer is polyurethane sponge. The flame-retardant functional layer is combined with the PVC leather layer to form a flame-retardant PVC leather layer, and then the flame-retardant PVC leather layer is tightly combined with the elastic layer through flame compounding, flame-retardant glue compounding or flame-retardant hot melt adhesive compounding. The flame-retardant PVC leather compound has the characteristics of excellent flame retardancy, low smoke, low toxicity, low VOC, low atomization value, no peculiar smell, soft hand feeling, high peel strength, good resilience and the like, and can be widely applied to seats, safety seats, door plates, handrails and the like of cars, passenger cars, trucks, high-speed rails, bullet trains, urban railways, low-speed trains and the like.

Description

Technical field [0001] The present invention relates to the field of flame-retardant materials, particularly relates to a preparation method and application A vehicle interior composite flame-retardant PVC leather. Background technique [0002] In recent years, motor vehicle combustion accidents, the relevant state ministries issued a document that the vehicle interior materials fire test standard is an important factor in ensuring the safety of the vehicle. States for the vehicle interior fabric flammability has clear regulations, my country has proposed a new standard in fire-retardant performance requirements of the school bus, buses and trains with interior fabric, horizontal burn test indicators from the original burning speed ≤100mm / min decreased to ≤70mm / min. Flame retardant passenger interior materials only with reference to the level of national mandatory GB8410-2006 burning rate control, is not sufficient to effectively prevent fire retard the spread of fire. Theref...
