Modified inorganic powder material, preparation method thereof and aluminum-plastic panel core material containing modified inorganic powder material
The invention relates to a functional modified inorganic powder material and an aluminum-plastic panel core material prepared from the functional modified inorganic powder material. The weight percentage of inorganic powder in the modified inorganic powder material is 88-95%. The preparation method of the modified inorganic powder material comprises the following steps: (1) adding a monomer into inorganic powder, so that the monomer forms a coating structure on the outer surface of the inorganic powder, (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, and carrying out polymerization reaction on the polymer monomer under the action of the initiator to obtain inorganic powder of which the surface is covered with a polymer, (3) adding a linking agent into the inorganic powder reacted in the step (2), and (4) sequentially arranging a mechanical layer and an optional configuration layer on theinorganic powder. The tensile breaking strength of an aluminum-plastic panel core material prepared from the modified inorganic powder material is greater than or equal to 7MPa, the combustion heat value is less than or equal to 2.9 MJ, and the peel strength of an aluminum-plastic panel prepared from the aluminum-plastic panel core material is greater than or equal to 7MPa.
本发明涉及一种功能性改性无机粉体材料及由其制备得到的铝塑板芯材，其中改性无机粉体材料中无机粉体的重量百分比为88‑95%。所述改性无机粉体材料的制备方法包括如下步骤：（1）向无机粉体中加入单体，使单体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，使无机粉体经摩擦撞击自然升温至50‑100℃，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）反应后的无机粉体中加入链接剂；（4）在无机粉体上依次设置力学层，及可选的配置层。由本发明的改性无机粉体材料制备的铝塑板芯材的拉伸断裂强度大于等于7MPa、燃烧热值小于等于2.9MJ，由其制备的铝塑板的剥离强度大于等于7MPa。
