摘 要:通過(guò)共沉淀-脫水法制備了木質(zhì)素-蒙脫土復合物填料,并濕法混煉制備了木質(zhì)素-蒙脫土復合物填充三角帶底膠試驗膠。研究了硫磺和促進(jìn)劑的量、天然橡膠(NR)和順丁橡膠(BR)的質(zhì)量比對三角帶底膠試驗膠的硫化特性和力學(xué)性能的影響。并將木質(zhì)素-蒙脫土復合物填充三角帶底膠與炭黑填充的三角帶底膠進(jìn)行了比較。結果表明:增加硫磺和促進(jìn)劑的量,提高了三角帶底膠試驗膠的硬度和300%定伸應力。增加天然橡膠和順丁橡膠的質(zhì)量比提高了三角帶底膠試驗膠的拉伸強度。調整配方后三角帶底膠試驗膠的綜合性能已與N330填充膠料相當。 |

Abstract:A novel rubber filler,lignin-montmorillonite complex,was prepared by co-precipitation and dehydration of the mixture of montmorillonite and black liquor and used in the base rubber of V-belt manufactured by mechanical mixing method. The effects of the contents of sulphur and accelerator and the mass ratio of natural rubber(NR)to cis-1,4-polybutadiene rubber(BR)on the curing characteristics and the mechanical properties of the base rubber of V-belt were studied. The base rubber filled with lignin-montmorillonite complex was compared with a base rubber filled with carbon black. The results showed that the Shore A hardness and 300% modulus of the base rubber were increased as the content of sulphur and accelerator increased,and the tensile strength was increased as the mass ratio of NR to BR increased. After some adjustments of the formulation,the comprehensive properties of the base rubber filled with lignin-montmorillonite could achieve the standards of the base rubber filled with carbon black. |
Key words:lignin-montmorillonite complex;base rubber of V-belt;mechanical property;curing characteristic |
