Method for preparing high-density and high-flame-retardant resin-based electronic material

The invention discloses a method for preparing a high-density and high-flame-retardant resin-based electronic material, and the method comprises the following steps: firstly, using bismaleimide to obtain modified modify epoxy resin; adding halloysite nanotubes to a tetrabutyl titanate hydrolysis system, and adding a silane coupling agent as a surfactant to prepare a nano-titanium oxide/ halloysitenanotube composite, and finally adding the modified epoxy resin, the nano-titanium oxide/ halloysite nanotube composite to a high-mixer to mix, then adding an anti-aging agent and a dispersing agent,continuing mixing, performing extruding and granulating by an extruder to obtain a mixture material, and finally forming by hot-pressing of the obtained mixture material to obtain the electronic material. The electronic material not only has excellent stability but also has excellent flame retardancy. 本发明公开了种高密度高阻燃的树脂基电子材料的制备方法，具体包括以下步骤：首先以双马来酰亚胺为改性剂为改性环氧树脂；在钛酸四丁酯的水解体系中加入埃洛石纳米管，并加入硅烷偶联剂作为表面活性剂，制得纳米氧化钛/埃洛石纳米管复合材料，最后将改性环氧树脂
