摘 要: 研究了以碳酸鎳、硼酸酯和混合羧酸合成新的金屬橡膠粘合促進(jìn)劑硼酰化鎳的新方法。系統(tǒng)地考察了各種因素對(duì)合成硼酰化鎳的影響。以2-乙基己酸和硼酸三丁酯為有機(jī)原料合成的硼酰化鎳，通過檢測(cè)，與英國(guó)Manobond公司產(chǎn)品680 C比較，二者紅外光譜數(shù)據(jù)、300%定伸強(qiáng)度、拉伸強(qiáng)度、硬度和硫化曲線非常接近，而拉斷伸長(zhǎng)率、熱空氣老化的粘合性能則前者稍低。實(shí)驗(yàn)表明，制備的硼酰化鎳可用作金屬橡膠粘合促進(jìn)劑。

Abstract:The synthetic method for nickel borate acylate (NBA), a kind of rubbersteel cord adhesion promoter, through nickelous carbonate borate and mixed carboxylic acids was studied, and many factors influencing the synthesis of NBA were investigated systematically. By detection and comparison with product 680 C from Manobond Company of England, the NBA synthesized through isooctanoic acid and tributyl borate is very similar with product 680 C in IR data, 300% fixed extension strength, tensile strength, hardness and cure curve, and is a little lower than product 680 C in tensile failure extensibility and hot air aging. The experimental results show that the prepared NBA can be used as rubbersteel cord adhesion promoter.
