Preparation method of flame-retardant ultrahigh-temperature-resistant electromagnetic wave absorbing material
The invention relates to a preparation method of a flame-retardant ultrahigh-temperature-resistant electromagnetic wave absorbing material, which comprises the following steps: step 1, material selection; step 2, preparing slurry, namely adding resin, a dispersing agent, a defoaming agent and a flatting agent in corresponding parts by mass into a reaction container, and stirring for 15-25 minutes at the speed of 300-500r/min; adding certain parts of Fe-Si-Al micro powder, a flame retardant and a solvent in batches, then stirring for 30-60 minutes at the speed of 2000-3000r/min to enable the Fe-Si-Al micro powder, the flame retardant and the solvent to be completely dispersed in the solution, and filtering to obtain mixed slurry; 3, coating: coating the mixed slurry by a coating method, and baking to form a film; and 4, pressing: pressing the film material at a certain temperature and pressure by using a vulcanizing machine. The wave-absorbing material can tolerate 250 DEG C for a long time, and the problems that an existing wave-absorbing material is not resistant to high temperature and flammable are solved.
本发明涉及一种阻燃型耐超高温电磁波吸收材料的制备方法，包括以下步骤，步骤1：材料选取；步骤2：制备浆料，将相应质量份数的树脂、分散剂、消泡剂、流平剂加入到反应容器中，以300～500r/min的速率搅拌15～25min；分次加入一定份数铁硅铝微粉、阻燃剂、溶剂，然后以2000～3000r/min的速率搅拌30～60min，使其完全分散在溶液中，过滤得到混合浆料；步骤3：涂布，将混合浆料用涂布法涂布烘烤成膜；步骤4：压合，使用硫化机在一定温度、压力下压合膜材料。本发明的吸波材料可以长期耐受250℃，解决了现有吸波材料不耐高温、易燃的问题。
