MANUFACTURING METHOD OF POLYURETHANE ARTIFICIAL LEATHER HAVING INCOMBUSTIBILITY AND POLYURETHANE ARTIFICIAL LEATHER USING THE SAME

摘要

A manufacturing method of a polyurethane artificial leather having the flame resistant property and the polyurethane artificial leather according to the same are provided to manufacture the bead-shaped flame resistant agent including plural flame resistant agent particles and to impregnate the non-woven cloth to the impregnated mixing solution. A bead-shaped flame resistant agent is prepared(S110). The bead-shaped flame resistant agent has a spherical shape bead shape. Plural flame resistant particles are impregnated to the inside of a resin. Thereafter, the non-woven cloth is impregnated into the impregnated mixing solution mixed by the prepared bead-shaped flame resistant agent and polyurethane resin(S120). Thereafter, the sea component of the impregnated non-woven cloth is erupted by means of sodium hydroxide so that the weight is decreased(S130). Thereafter, the non-woven cloth is dyed by acid dyes so that a suede-shape polyurethane artificial leather is manufactured(S140). The non-woven cloth is treated by the textile combining process so that a dried-type polyurethane artificial leather is manufactured(S150). Further, the flame resistant agent is one or more selected from a group consisting of phosphorus based flame resistant agent, halogen based flame resistant agent and melamin based flame resistant agent.
