Composite heat insulation ball as well as preparation method and application thereof
The invention relates to a composite heat insulation ball as well as a preparation method and application thereof. The ball comprises a ball core which is of a porous spherical structure; the ball core is made of aluminum oxide; the isolating layer is arranged on the outer surface of the ball core; the isolating layer can prevent liquid and/or solid from permeating into the surface of the ball core; the coating layer is adhered to the outer surface of the isolating layer through an adhesive A; the coating layer is made of aluminum oxide and aerogel; the mass ratio of the aerogel to the aluminum oxide is 1: (15-25); the reflecting layer is adhered to the outer surface of the coating layer through an adhesive B, and the reflecting layer is made of a material with the performance that the reflectivity of middle and far infrared light is larger than 0.3-0.6 and the emissivity of the middle and far infrared light is 0.7-0.9; and the thickness of the reflecting layer is 80-120 [mu] m. The technical problem to be solved is how to provide a composite heat-insulating ball, so that a heat-insulating repair molding material prepared from the composite heat-insulating ball can effectively block a heat transfer process mainly comprising heat radiation at a high temperature of 800-1500 DEG C.
本发明是关于一种复合隔热球及其制备方法和应用。其包括：球芯，其为多孔球状结构；所述球芯的材质为氧化铝；隔离层，其设置于所述球芯的外表面；所述隔离层能够防止液体和/或固体渗入到所述球芯表面；包覆层，其通过粘接剂A粘接在所述隔离层外表面；所述包覆层的材质包括氧化铝和气凝胶；所述气凝胶和氧化铝的质量比为1:15～25；和，反射层，其通过粘接剂B粘接在所述包覆层外表面，所述反射层的材质为具有对中远红外光反射率大于0.3～0.6和发射率为0.7～0.9性能的材料；所述反射层的厚度为80～120μm。所要解决的技术问题是如何提供一种复合隔热球，使其制得的隔热修补成型材料能够在800～1500℃的高温下有效阻挡以热辐射为主的传热过程。
