    • PROBLEM TO BE SOLVED: To provide a flame-retardant synthetic leather having a high-level flame retardance without deteriorating physical properties, and producible in a labor-saved process, and to provide a method for producing the synthetic leather. SOLUTION: The flame-retardant synthetic leather is obtained by laminating a skin layer composed of a polyurethane resin formed by reacting a hot-melt urethane polyol prepolymer comprising a phosphorus-based flame retardant added thereto with a urethane curing agent, and a protective layer composed of a polyurethane resin in the order on one of the surfaces of a fibrous substrate. When producing the flame-retardant synthetic leather, the phosphorus-based flame retardant is added to the hot-melt urethane polyol prepolymer in a hot molten state, and the resultant mixture is then mixed with the urethane curing agent to prepare a prepolymer composition. The resultant prepolymer composition in the hot molten state is applied to [1] the fibrous substrate. Otherwise, the prepolymer composition in the hot molten state is applied onto [2] a mold release substrate, and the fibrous substrate is laminated to the coated surface. Thereby, the skin layer composed of the polyurethane resin is formed. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供具有高阻燃性的阻燃合成革,而不会使物理性能下降,并且可以节省劳动生产,并提供合成皮革的制造方法。 解决方案:阻燃合成革是通过将由包含添加有磷系阻燃剂的热熔氨基甲酸酯多元醇预聚物与氨基甲酸酯固化剂反应而形成的聚氨酯树脂层叠的表皮层和 保护层由纤维基材的一个表面上的顺序依次由聚氨酯树脂构成。 在制造阻燃性合成革时,将磷系阻燃剂以热熔状态添加到热熔氨基甲酸酯多元醇预聚物中,然后将所得混合物与聚氨酯固化剂混合,制备预聚物组合物。 将所得到的热熔融状态的预聚物组合物施加到[1]纤维基材上。 否则,将热熔融状态的预聚物组合物施加到[2]脱模基材上,并将纤维基材层压到涂布表面上。 由此,形成由聚氨酯树脂构成的表皮层。 版权所有(C)2009,JPO&INPIT
