摘要

研究了红麻纤维填充量和粒径对红麻纤维填充天然胶乳泡沫材料力学性能的影响。采用Dunlop法制备NRLF。将红麻纤维筛选到97、144和200µm的粒径，并以0、1、3、5和7‰的橡胶纤维含量掺入橡胶硫化胶中。增加红麻纤维在NRLF中的负荷，导致拉伸强度、断裂伸长率和回复率降低，但增加了100%模量(M100)、抗压强度、压缩集定、硬度和泡沫密度。在相同的红麻纤维负荷下，越小尺寸的红麻纤维填充NRLF具有较高的拉伸性能、抗压强度、压缩集度和硬度。扫描电镜结果表明，随着红麻纤维载荷和粒径的增大，NRLF的孔径增大，从而导致了NRLF的抗拉强度、M100、抗压强度和硬度的增大。

The effects of filler contents and particle sizes on properties of green kenaf-filled natural rubber latex foam

The effects of filler loading and size of kenaf fibre on the mechanical properties of kenaf fibre-filled natural rubber latex foam (NRLF) have been studied. The NRLF was prepared by using the Dunlop method. The kenaf fibre was sieved to 97, 144 and 200 µm particle sizes and incorporated into the rubber vulcanizates at 0, 1, 3, 5 and 7 part per hundred rubber fibre contents. Increasing kenaf fibre loading in NRLF resulted in the reduction of tensile strength, elongation at break and recovery percentage but increased in modulus at 100% (M100), compression strength, compression set, hardness and foam density. At the same kenaf fibre loading, smaller size of kenaf fibre-filled NRLF showed higher tensile properties, compression strength, compression set and hardness. Scanning electron microscope demonstrated that as kenaf fibre loading and size increased, a larger pore size of NRLF was formed and this led to tensile strength, M100, compression strength and hardness.

期刊介绍： Cellular Polymers is concerned primarily with the science of foamed materials, the technology and state of the art for processing and fabricating, the engineering techniques and principles of the machines used to produce them economically, and their applications in varied and wide ranging uses where they are making an increasingly valuable contribution. Potential problems for the industry are also covered, including fire performance of materials, CFC-replacement technology, recycling and environmental legislation. Reviews of technical and commercial advances in the manufacturing and application technologies are also included. Cellular Polymers covers these and other related topics and also pays particular attention to the ways in which the science and technology of cellular polymers is being developed throughout the world.
