摘 要:通過(guò)共沉淀-脫水法制備了木質(zhì)素-硅藻土復合物填料,并濕法混煉制備了木質(zhì)素-硅藻土復合物填充三角帶底膠實(shí)驗膠。通過(guò)無(wú)轉子硫化儀、電子萬(wàn)能試驗機、邵氏硬度計研究了硫磺和促進(jìn)劑的量、天然橡膠和順丁橡膠的量對三角帶底膠實(shí)驗膠的硫化特性和力學(xué)性能的影響,并將木質(zhì)素-硅藻土復合物填充三角帶底膠與炭黑填充的三角帶底膠實(shí)驗膠進(jìn)行了比較。結果表明:增加硫磺和促進(jìn)劑的量,提高了三角帶底膠實(shí)驗膠的硬度和300%定伸應力;將順丁橡膠替換成天然橡膠則提高了三角帶底膠實(shí)驗膠的拉伸強度。配方調整后三角帶底膠實(shí)驗膠的綜合性能已與N330填充膠料相當。 |

Abstract:A novel rubber filler, lignin-diatomite complex, was prepared by co-precipitation and dehydration of the mixture of black liquor and diatomite and used in the base rubber of V-belt manufactured by mechanical mixing method. The effect of the content of sulphur and accelerator, the mass of natural rubber (NR) and 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- diatomite complex was compared with that filled with carbon black. The experiments 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 of the base rubber was increased when BR was replaced with NR. After some adjustments of the formulation, the comprehensive properties of the base rubber filled with lignin-diatomite were similar to those of the base rubber filled with carbon black. |
Key words:base rubber of V-belt;lignin-diatomite complex;curing characteristic; mechanical property |
