Modified inorganic powder material, preparation method and membrane material containing modified inorganic powder material
The invention relates to a functional modified inorganic powder material and a preparation method thereof. The weight percentage of inorganic powder in the modified inorganic powder material is 50-65%. The method comprises the following steps: (1) sequentially adding monomers into inorganic powder, wherein the monomers are attached to the outer surface of the inorganic powder to form a coating structure; (2) adding an initiator into the mixture obtained in the step (1), naturally heating the inorganic powder to 50-100 DEG C through friction impact under the condition of high-speed rotation, and performing polymerization reaction on the polymer monomer under the action of the initiator under the condition to obtain inorganic powder of which the surface is covered with a polymer; (3) addinga linking agent into the inorganic powder of which the surface is covered with the polymer after reaction in the step (2); and (4) sequentially arranging a tough layer, a mechanical layer and an optional configuration layer on the inorganic powder of which the surface is covered with the polymer. Compared with the prior art, the tensile strength and breaking strength of a film prepared from the modified inorganic powder material are greatly improved.
本发明涉及一种功能性改性无机粉体材料及其制备方法，改性无机粉体材料中无机粉体的重量百分比为50‑65%。所述方法包括如下步骤：（1）向无机粉体中依次加入单体，所述单体附着在无机粉体的外表面形成包覆结构；（2）向步骤（1）的混合物中加入引发剂，在高速旋转条件下使无机粉体经摩擦撞击自然升温至50‑100℃，在此条件下聚合物单体在引发剂的作用下发生聚合反应，得到表面覆盖有聚合物的无机粉体；（3）向步骤（2）反应后的表面覆盖有聚合物的无机粉体中加入链接剂；（4）在表面覆盖有聚合物的无机粉体上依次设置韧性层、力学层，及可选的配置层。由本发明的改性无机粉体材料制备得到的膜的拉伸强度和断裂强度相对于现有技术有大幅的提高。
