摘要
２－甲基丙烯酸和对氨基苯甲酸按一定摩尔比混合后与硅酸钠、硝酸铝反应，将制得的活性硅铝氧烷溶胶（粒径为６～１５μｍ，灰分为３０％～６０％）填充到ＮＢＲ胶料中，其硫化胶性能与无填充活性硅铝氧烷溶胶者相比，拉伸强度可提高２～６倍，具有明显的增强作用和硫化促进作用。用２－甲基丙烯酸和硬脂酸制得的活性硅铝氧烷溶胶对ＮＢＲ硫化胶无增强作用。
The active aluminosiloxane sol(particle diameter 6～15μm,ash 30%～60%)was prepared by the reaction of the mixture of 2-methylacrylic acid and aminobenzoic acid with sodium silicate and aluminium nitrate.The results showed that the tensile strength of NBR vulcanized rubber filled with the active aluminosiloxane sol increased 2～6times.It had obvious reinforcing and vulcanization accelerating effects.It was also showed that the active aluminosiloxane sol from 2-methylacrylic acid and stearic acid had no reinforcing effect on NBR vulcanized rubber.
