High-strength high-temperature-resistant thermal insulation material and preparation method thereof
The invention relates to a high-strength high-temperature-resistant thermal insulation material and a preparation method thereof. The method comprises the following steps: uniformly dispersing zirconium oxide fibers and zirconium carbide fibers with water, and making wet fiber sheets with paper; solid phosphate, magnesia and chromic oxide are mixed and subjected to ball milling, filler is obtained, a phosphate solution is added, mixing and stirring are conducted, and the high-temperature-resistant phosphate adhesive is obtained; the surface of the reflecting screen is coated with a high-temperature-resistant phosphate adhesive, and the modified reflecting screen is obtained through curing; a plurality of modified reflecting screens and a plurality of fiber wet sheets are alternately arranged, and the high-strength high-temperature-resistant thermal insulation material is prepared through mold pressing and curing; in the alternate arrangement, a fiber wet sheet is arranged between every two modified reflecting screens, and the surface of each fiber wet sheet is coated with a high-temperature-resistant phosphate adhesive. According to the method, the high-temperature crystal form of the phosphate is controlled, meanwhile, oxidation inhibition treatment is conducted on the reflecting screen through the phosphate adhesive, the interface stability of the multi-layer material is improved, and the purpose of durable application of the material under the ultra-high-temperature condition is achieved.
本发明涉及一种高强度耐高温隔热材料及其制备方法。所述方法：用水将氧化锆纤维和碳化锆纤维分散均匀，抄造出纤维湿片；将固体磷酸盐、镁砂和氧化铬混合并球磨，得到填料，加入磷酸盐溶液混合并进行搅拌，得到耐高温磷酸盐粘接剂；往反射屏的表面涂覆耐高温磷酸盐粘接剂，经固化，得到改性反射屏；将多个改性反射屏与多个纤维湿片交替设置，经模压与固化，制得高强度耐高温隔热材料；在交替设置中，每两个改性反射屏之间设置一个纤维湿片，纤维湿片的表面涂覆有耐高温磷酸盐粘接剂。本发明实现了对磷酸盐高温晶型的控制，同时以磷酸盐粘接剂对反射屏进行氧化抑制处理，提升了多层材料的界面稳定性，达到了材料超高温条件下持久性应用的目的。
