原位表面改性纳米氧化锌对NR胶料性能的影响

对纳米氧化锌进行原位表面改性，研究改性纳米氧化锌对NR胶料性能的影响。结果表明：与普通氧化锌相比，改性纳米氧化锌的团聚程度减轻，粒径分布均匀；在改性纳米氧化锌用量为5份时，胶料的t₁₀延长，t₉₀缩短，硫化胶的拉伸强度和拉断伸长率分别提高了12.89%和6.12%。;The surface of nano-zinc oxide was in-situ modified,and the influence of modified nano-zinc oxide on the properties of NR compound was investigated.The results showed that,when compared to common zinc oxide,the modified nano-zinc oxide had less agglomeration,and uniform distribution of particle size,when addition level of modified nano-zinc oxide was 5 phr,t₁₀ of the compound was extendedt₉₀was shortened,and the tensile strength and elongation at break of vulcanizate were increased by 12.89% and 6.12% respectively
