Phosphate thermal insulation layer with strong interface chemical bonding, preparation method thereof and composite material
The invention provides a phosphate thermal insulation layer with strong interface chemical bonding. The phosphate thermal insulation layer comprises a matrix and ceramic filler, wherein the matrix isprepared from Al(OH)3, H3PO4 and CuO. The invention further provides a preparation method of the phosphate thermal insulation layer with the strong interface chemical bonding function. According to the phosphate heat-insulating layer, the copper phosphate is modified through the ceramic filler, and the high-temperature resistance and high emissivity of the ceramic filler and the excellent mechanical property and low heat conductivity of a copper phosphate material are integrated, so that the phosphate heat-insulating layer has the effects of high-temperature resistance and heat insulation; andmeanwhile, the copper phosphate material can be cured and formed at normal temperature, so that the controllability is high, and the heat insulation requirements of various aerospace products can bewell met. Therefore, the phosphate sub-thermal insulation layer provided by the invention has the advantages of excellent performance, simple process, short preparation period, low production cost, high controllability and the like.
本发明提供了一种强界面化学键合的磷酸盐隔热层，包括基体和陶瓷填料；所述基体由Al(OH)、HPO、CuO制备得到。本申请还提供了所述强界面化学键合的磷酸盐隔热层的制备方法。本申请磷酸盐隔热层通过陶瓷填料改性磷酸铜，集合了陶瓷填料耐高温、发射率高与磷酸铜材料优异的力学性能与低的热导率，使其具有耐高温和隔热的作用；同时由于磷酸铜材料在常温下即可固化成型，可控性高，可以很好的满足多种航天产品的隔热需求。因此，本发明提供的磷酸亚隔热层在具有优异性能的同时还具有工艺简单、制备周期短、生产成本低、可控性高等优势。
