摘要： 利用磨盤型力化學(xué)反應(yīng)器強(qiáng)大的剪切、環(huán)向應(yīng)力、擠壓、拉伸和摩擦作用,用水作分散介質(zhì),建立濕磨粉碎方法,制備廢舊輪胎橡膠超細(xì)粉體。結(jié)果表明:碾磨21次膠粉的粒徑可控制在0.3到5μm之間,小于1μm的膠粉達(dá)85%以上,同時(shí)濕磨膠粉在水中具有很好的分散穩(wěn)定性,濕法碾磨后膠粉的親水性大大提高了。 In this paper,using water-surfactant mixture as dispersing medium,ultra-fine waste tire rubber(WTR) powders were prepared by pan-milling in wet state,a mechanochemical route based on a complex combination of shearing,compression,stretching and friction actions.The experimental results indicated that super-fine waste tire rubber powders with diameter 0.3~5μm were prepared by pan-milling with 21 cycles,the content of particle size smaller than 1μm was more than 85%.The experimental results also showed that su...
