Surface gradient hardening method of nanometer heat insulation material
The invention discloses a surface gradient hardening method of a nanometer heat insulation material, and belongs to the technical field of nanometer heat insulation material preparation. The preparation method comprises the following steps: ball-milling boron oxide powder and white oil in a dry environment to obtain modified boron oxide powder; uniformly mixing the modified boron oxide powder with boron nitride powder, boron carbide powder and polymer particles to obtain a composition A; adding the composition A into a solvent B, and stirring until the polymer particles are completely dissolved to obtain a composition B; uniformly coating the composition B on the inner surface of the ceramic box, and uniformly adhering the composition A on the inner surface of the ceramic box after the solvent B is completely volatilized; and placing the nano heat insulation material component in a ceramic box, sealing the ceramic box, placing the ceramic box in a muffle furnace, performing heat treatment, cooling and taking out the ceramic box to obtain the nano heat insulation material block with the gradient hardened surface. The problems that the surface structure of a nanometer heat insulation material component is loose, and powder is prone to falling can be solved.
本发明公开一种纳米隔热材料的表面梯度硬化方法，属于纳米隔热材料制备技术领域。在干燥环境下，将氧化硼粉、白油球磨得到改性氧化硼粉；将改性氧化硼粉与氮化硼粉、碳化硼粉、高分子颗粒均匀混合，得到组合物A；将组合物A加入到溶剂B中，搅拌至高分子颗粒完全溶解，得到组合物B；将组合物B均匀涂至陶瓷匣子内表面，待溶剂B挥发完毕后，组合物A在陶瓷匣子内表面均匀附着；将纳米隔热材料构件置于陶瓷匣子内部，将陶瓷匣子密封，置于马弗炉中，热处理后冷却取出，得到表面梯度硬化的纳米隔热材料块体。本发明能够解决纳米隔热材料构件表面结构疏松、易掉粉的问题。
