综述硅藻土的提纯、改性及其在橡胶中的应用。硅藻土的提纯包括水洗、酸洗、焙烧等，采用隔绝空气焙烧的高烧失量硅藻土可以用作橡胶填料。硅藻土属酸性矿物，可选用硬脂酸和硅烷等作为改性剂，以提高其与橡胶基体的相容性，改善其在橡胶中的分散。硅藻土可部分替代炭黑和/或白炭黑作为橡胶的补强剂，并可用于生产白炭黑，是一种生产彩色橡胶制品的新原料。硅藻土在橡胶中还可作为氢氧化镁等的阻燃协效剂等使用。

The puriifcation and modiifcation of diatomite, and its application in rubber are reviewed in this paper. The puriifcation process includes water washing, acid treatment and calcinations. The diatomite having high weight loss after being treated with calcinations in the absence of air can be used as filler for rubber materials. Due to the acidic nature of diatomite, stearic acid and silane coupling agent are suitable modiifers to improve the compatibility between diatomite and rubber and improve the dispersion of diatomite in rubber. Diatomite can be used to partially replace carbon black or silica in the reinforcement system for rubber compound. Diatomite can also be used to produce silica. It is a new ifller to formulate colored rubber products. In addition, diatomite shows the synergistic lfame retardant effect with magnesium hydroxide in rubber materials.
