单级配和双级配磁流变复合胶的制备及其流变特性
Preparation and Rheological Property of Single- and Double-Grading Magnetorheological Composite Gel
摘 要
在以甲基硅油、明胶、琼脂胶为原料制备的复合胶状基体中添加了单一粒径(单级配)和两种粒径级配(双级配)的改性羰基铁粉, 通过真空减压制备了单级配和双级配磁流变复合胶, 研究了羰基铁粉粒径及其级配对该磁流变复合胶流变性能的影响。结果表明: 单级配磁流变复合胶的剪切强度随着羰基铁粉粒径的减小逐渐减小; 90%(质量分数, 下同)未球磨混合10%球磨羰基铁粉的双级配磁流变复合胶的剪切强度则随球磨时间的延长(羰基铁粉粒径的减小)先增后降, 球磨24 h后的剪切强度可达99.6 kPa, 相比于未球磨单级配磁流变复合胶, 其剪切强度提高了17.8 kPa。

Abstract
The modified carbonyl iron powders with single particle size (single-grading) and binary particle sizes (double-grading) were added in the composite gel, which was prepared by using methyl silicone oil, gelatin and agaropectin colloids as raw materials, and then the single- and double-grading magnetorheological composite gel (MRCG) was prepared by vacuum decompression. The effects of particle size and gradation of carbonyl iron powder on the rheological behaviors of the MRCG were studied. The results show that the shear strength of single-grading MRCG decreased gradually with the decrease of the carbonyl iron particle size. However, the shear strength of the double-grading MRCG with the gradation of 90wt% un-ball-milled and 10wt% ball-milled carbonyl iron powders first increased then decreased with the increase of milling time (the decrease of the carbonyl iron particle size) and reached 99.6 kPa after ball milling for 24 h, which was 17.8 kPa larger than that of un-ball-milled single-grading MRCG.
