| 摘 要： | 以亲水性聚硅氧烷KGF-903共混改性天然乳胶,通过拉力试验、老化试验、接触角测量和扫描电子显微镜等研究了聚硅氧烷的添加量对天然乳胶力学性能、抗老化性能、亲水性能和表面形貌的影响。结果表明,KGF-903含量在1.5%时拉伸强度有最佳的改性效果;KGF-903添加量约为3%时断裂伸长率达到最大,老化前后的断裂伸长率比改性前分别提高57%和50%。随着KGF-903含量的增加,改性天然乳胶片的水接触角逐渐减小;扫描电子显微镜观察的结果表明,添加聚硅氧烷能改变乳胶的分散状态。利用小试的最佳配方(即KGF-903的添加量为1.5%)生产了2批次医用导尿管,其表面光洁度、导尿管球囊的成品率、管身硬度、连接器与导尿管排泄锥形接口所承受的拉力和充气漏斗与引流漏斗连接处所承受的拉力等均有显著的提高,有效改善了产品的质量。 |

| Abstract: | The natural rubber latexes were blended with hydrophilic organosiloxane KGF-903 for the improvement of its performance. The effect of the content of organosiloxane on blended natural rubber latex was investigated through mechanical,antiaging,hydrophilic and morphological measurement. It indicated that the mechanical and antiaging properties were improved with the addition of organosiloxane at an optimal content of 1.5%,at which the tensile strengths of improved natural rubber before and after the aging were... |
| Keywords: | nature rubber latex organosiloxane blend mechanical and antiaging properties hydrophilicity |
