【摘要】：硅藻巖是生物質(zhì)沉積巖,因其具有質(zhì)輕、大的比表面積、超強(qiáng)的吸附性、隔音、耐磨、耐熱以及耐腐蝕等特點(diǎn)而被廣泛應(yīng)用于化工、石油、建材、生物醫(yī)藥衛(wèi)生以及環(huán)保等眾多領(lǐng)域,其與白炭黑成分結(jié)構(gòu)類似,可作為白炭黑的替代品來增強(qiáng)橡膠材料。本文首先對(duì)黑龍江省黑河硅藻巖進(jìn)行了改性,考察了不同改性劑的改性效果,結(jié)果表明偶聯(lián)劑Si69的改性效果較好。采用機(jī)械共混法制備了改性硅藻巖/橡膠復(fù)合材料,通過力學(xué)性能測(cè)試和SEM分析確定了最適合硅藻巖增強(qiáng)的橡膠是氟橡膠、三元乙丙橡膠和丙烯酸酯橡膠,硅藻巖能均勻分散在這三種橡膠基體中,相容性良好且機(jī)械性能優(yōu)異。
[Abstract]:Diatoms are biomass sedimentary rocks, which are widely used in chemical, petroleum and building materials because of their light weight, large specific surface area, super absorbability, sound insulation, wear resistance, heat resistance and corrosion resistance.Biopharmaceutical, environmental protection and other fields, similar to the composition of silica, can be used as a substitute for silica to strengthen rubber materials.In this paper, the modification of Heihe diatom in Heilongjiang Province was carried out, and the modification effects of different modifiers were investigated. The results showed that the modification effect of coupling agent Si69 was better.The modified diatom / rubber composites were prepared by mechanical blending method. The results of mechanical properties test and SEM analysis showed that the most suitable rubber reinforced by diatom was fluorine rubber, ethylene propylene diene diene diene monomer rubber and acrylate rubber.Diatoms can be uniformly dispersed in these three rubber substrates with good compatibility and excellent mechanical properties.
