| description | The invention relates to a flame-retardant leather preparation process based on nitrogen-phosphorus-aluminum. The flame-retardant leather preparation process comprises the following steps of softening, retanning, neutralizing, filling and dyeing, fat liquoring and color register. Melamine, tetrakis (hydroxymethyl) phosphonium sulfate, glutaraldehyde and aluminum sulfate are utilized to construct a nitrogen-phosphorus-aluminum synergistic flame-retardant filler, and the nitrogen-phosphorus-aluminum synergistic flame-retardant filler is introduced into collagen fiber bundles of leather through a replacement method and a filling process, so that the leather has good synergistic flame-retardant performance, and the flame-retardant grade can reach UL 94V-0.
本发明涉及一种基于氮-磷-铝的阻燃皮革制备工艺，包括如下步骤：回软→复鞣→中和→填充、染色→加脂→套色。本申请通过利用三聚氰胺、四羟甲基硫酸磷、戊二醛和硫酸铝构建氮-磷-铝协同阻燃填料，并通过替换法利用填充工艺将其引入到皮革的胶原纤维束，使皮革具有良好的协同阻燃性能，阻燃等级可达到UL 94V-0。 |
