摘要
研究金属-有机骨架(MOFs)多孔材料ZIF-8的特性,并用其部分替代白炭黑和氧化锌用于轮胎胎面胶。结果表明:ZIF-8的骨架上含有大量金属活性位点,且大部分金属活性位点裸露在外,使其具有更高的催化性能,ZIF-8具有特殊的有机-无机骨架结构,比表面积大,易分散且对小分子吸附性更好;在轮胎胎面胶中加入ZIF-8,可以大幅度降低氧化锌和白炭黑的用量,缩短硫化时间,提高胶料的物理性能,胶料具有更高的拉伸性能且保持较低的温升。
The properties of porous metal-organic frameworks(MOFs) material ZIF-8 was investigated,and it was used to replace part of the silica and zinc oxide in tire tread compound. The results showed that,the frameworks of ZIF-8 contained a large number of metal active sites,and most of the metal sites were exposed which enabled high catalytic performance. ZIF-8 had a special organic-inorganic skeleton structure,large specific surface area,easy dispersion and good adsorption for small molecules. With the addition of ZIF-8 in tire tread compound,the amount of zinc oxide and silica could be greatly reduced,the curing time was shortened,the physical properties of the compound were improved,the tensile properties of the compound were higher,and the low heat build-up property was maintained.
