选取数种纳米填料对硅橡胶进行补强,结果发现不同的纳米填料对硅橡胶的影响区别很大,白炭黑会使硅橡胶的拉伸强度提高;纳米三氧化二铁粒子越小,补强效果越好,当纳米三氧化二铁含量达到10%,会使硅橡胶的强度提高达到5.16Mpa,而且会使硅橡胶的热稳定性大幅提高,TGA曲线中535℃时残留质量由空白胶的30.75%提高到了86.15%;但是纳米炭化硅、氮化硅会对硅橡胶产生强烈的阻聚作用,以至于硅橡胶包覆层无法聚合。 Select a few kinds of nano-filler on the silicone rubber reinforcement, found that different nano-filler on the impact of silicone rubber vary greatly, silica will increase the tensile strength of silicone rubber; nano-iron oxide particles smaller, make up Strong effect is better, when the content of nano ferric oxide reaches 10%, the strength of silicone rubber will be increased to 5.16Mpa, and the thermal stability of silicone rubber will be greatly improved. The residual mass of TGA curve at 535 ℃ consists of blank glue Of the 30.75% to 86.15%; but nano-silicon carbide, silicon nitride will have a strong resistance to the role of silicone rubber, so that the silicone rubber coating can not be polymerized.
