摘　　要：试验研究了4种抗撕裂油、4种醛鞣剂、4种回湿剂、大小丙烯酸树脂、铬粉和含铬单宁处理黄牛二层蓝革后,成革的抗张强度和撕裂强度。发现抗撕裂油LWKM、脂肪醛PF、唑烷OXB和回湿剂NP-2处理皮革后,其抗张强度和撕裂强度较好;在铬粉与含铬单宁的对比中,发现AB铬粉复鞣二层蓝革,可以获得更高的机械强度;大分子丙烯酸树脂填充二层蓝革后,其抗张强度优异,而小分子丙烯酸树脂填充二层蓝革后,其撕裂强度更好。4 tear resistance oils, 4 aldehyde tanning agents, 4 rewetting agents, chrome tanning agent and chrome containing tannin, 2 acrylic polymers were used to treat wet split leather. And the tensile strength and tear strength of resultant leathers were determined. It shows that the leather made by oil LWKM, aliphatic aldehyde PF, oxazolidine OXB and rewetting agent NP - 2 respectively has good tensile strength and tear strength. The wet blue retanned by chrome powder AB got a better strength than that of the leather retanned by chrome containing tannin. The leather filled by big molecule acrylic resin got a better tensile strength while the leather filled by small molecule acrylic resin got better tear strength.
