Solid waterproof additive based on magnesium oxide powder mixing ratio and mixing ratio method

A preparation method of the solid waterproof additive based on the magnesium oxide powder mixing ratio comprises the following steps: S1, raw material selection: selecting white carbon black, high-hydrogen-content organic silicon resin and ultrafine powder grade talc raw materials; s2, pouring the white carbon black, the high-hydrogen-content organic silicon resin and the ultrafine-powder-grade talc raw material into a reaction kettle according to a certain proportion, and mixing and stirring for 30 minutes to obtain mixed slurry; s3, performing high-temperature baking on the mixed slurry to obtain a solid material; s4, pouring the solid material into a jaw crusher, and crushing the solid material into a particle material; and S5, carrying out ball milling on the granular material to obtain the powdery solid waterproof additive. 一种基于氧化镁粉混合配比的固体防水添加剂，制备方法如下：S1、原料选取，选取白炭黑、高含氢有机硅树脂和超细粉级别滑石原料；S2、将白炭黑、高含氢有机硅树脂和超细粉级别滑石原料按照一定比例倒入反应釜内混合搅拌30min，得到混料浆体；S3、将混料浆体进行高温烘制，得到固体料；S4、将固体料倒入鄂式粉碎机中，破碎成颗粒物料；S5、对颗粒物料进行球磨，得到粉末状固体防水
