Thermal insulation material and preparation method thereof
The invention belongs to the technical field of thermal insulation, and discloses a thermal insulation material and a preparation method thereof. The thermal insulation material comprises an upper panel layer, a middle sandwich layer and a lower panel layer from top to bottom, wherein the upper panel layer and the lower panel layer are fiber-reinforced resin-based composite sheets, and the middlesandwich layer is composed of aerogel powder, a heat insulation filler, an infrared opacifying agent and short fibers; and the upper panel layer, the middle sandwich layer and the lower panel layer are integrally formed. The preparation method comprises the following steps: fully mixing the aerogel powder, the heat insulation filler, the infrared opacifying agent and the short fibers to obtain a mixture A, and performing compression molding to obtain a sandwich layer B; and flatly laying a fiber-reinforced resin-based prepreg tape corresponding to the lower panel layer, flatly laying the sandwich layer B on the upper surface of the fiber reinforced resin-based prepreg tape corresponding to the lower panel layer, then continuously laying the fiber reinforced resin-based prepreg tape corresponding to the upper panel layer on the upper surface of the sandwich layer B, and carrying out hot press molding. According to the preparation method, the problem of high brittleness of aerogel is well solved.
本发明属于隔热保温技术领域，公开一种隔热保温材料及其制备方法。由上至下包括上面板层、中间夹心层、下面板层，上、下面板层为纤维增强树脂基复合片，中间夹心层由气凝胶粉、隔热填料、红外遮光剂、短纤维组成；上面板层、中间夹心层、下面板层之间为一体成型。将气凝胶粉、隔热填料、红外遮光剂、短纤维充分混合，得到混合料A，压制成型，得到夹心层B；将与下面板层对应的纤维增强树脂基预浸带平铺放置，将夹心层B平铺于与下面板层对应的纤维增强树脂基预浸带的上表面，接着在夹心层B的上表面再继续铺设与上面板层对应的纤维增强树脂基预浸带，热压成型。本发明很好地解决了气凝胶脆性大的问题。
