The invention discloses a preparation method for a thin flame-retardant non-woven fabric applied to vehicles. The preparation method comprises the following steps: compounding polyester fibers and viscose fibers in a needling manner so as to form a base fabric; uniformly mixing a flame retardant and water-based glue to form a flame-retardant adhesive, and mixing the flame-retardant adhesive with black color paste and water to obtain an impregnation solution; soaking the base fabric obtained after needling in the impregnation solution; and spraying powder particles on the impregnated base fabric so as to obtain the flame-retardant non-woven fabric with a gram weight of 100 to 150 g/m<2>, wherein the powder particles are a mixture of the powder particles of polyethersulfone resin and phenolic resin. Compared with conventional flame-retardant non-woven fabrics, the flame-retardant non-woven fabric of the invention is reduced in thickness, saves materials and lowered in production cost, and achieves good flame retardant effect at the same time.
