Preparation method of efficient composite active material zinc oxide powder

The invention relates to a preparation method of efficient composite active material zinc oxide powder, particularly to a preparation method of efficient composite active zinc oxide material powder for assisting rubber and plastic material molding vulcanization preparation. The method mainly comprises the following steps: mixing an alkali liquor with a calcium compound; adding a zinc salt solution, directly carrying out chemical reaction mixing to obtain a precipitation solution with a predetermined pH value, carrying out a proper filtering and dewatering process to obtain a powdery intermediate product, and properly drying the powdery intermediate product to prepare the zinc oxide crystal growth material with nanoscale high-efficiency composite activity, so that the goal of multi-elementutilization of the zinc oxide powder industry is provided. 本发明的一种高效复合活性材料氧化锌粉末的制备方法是一种提供橡塑料成型硫化制备辅助用的高效复合活性氧化锌材料粉末的制备方法，主要在通过以碱液与钙化合物的混合，配合锌盐溶液添加，使其直接进行化学反应混合，藉以获得预定PH值的沉淀液，经适当滤净除水程序，得到粉末状中间产物，将其适当烘干，制成具纳米级高效复合活性的氧化锌长晶材料，提供氧化
