牛皮再生革强度的改性研究

Study on Modification of Regeneration Cowhide Leather's Strength

文章对牛皮再生革制品的强度进行了改性研究,找到了增强牛皮再生革强度的工艺条件:不加丙烯酸丁酯BA辐照18 h天然胶乳或50%苯丙乳液加入皮毛中后,其片皮革的强度比原来的天然胶乳提高了55.6%;而在对片皮革处理样品中,不含TT、70℃、2 MPa下,处理30 min和60 min或者70℃、1 MPa下处理10 min的样品,强度大于9 MPa,应力为47 N左右,可满足牛皮再生革的强度要求。

The paper below is concerned about research of modification of regeneration cowhide leather＇s strength, which finds the technological conditions of increasing regeneration cowhide leather＇s strength： After natural latex without the addition of butyl acrylate BA irradiated 18 h or 50 % styrene acrylic emulsion are added into fur, the strength of this piece of leather is increased by 55.6 % compared to the original natural latex; Furthermore, in the piece of leather processing samples, without TT, 70 degrees, 2 MPa, dealing with the sample in 30 min and 60 min or 70 degrees, 1 MPa, the strength is larger than 9 MPa, the stress is about 47 N, all above can reach the requirement of regeneration cowhide leather＇s strength.
