Multi-temperature-zone multi-layer composite thermal insulation material and preparation method thereof
The invention relates to the field of thermal insulation materials, and discloses a multi-temperature-zone multi-layer composite thermal insulation material and a preparation method thereof. The composite heat insulation material comprises at least one high-temperature area heat insulation layer, at least one medium-temperature area heat insulation layer and at least one low-temperature area heat insulation layer, each of the high-temperature area heat insulation layer, the medium-temperature area heat insulation layer and the low-temperature area heat insulation layer comprises an inorganic fiber base material, inorganic heat insulation powder, SiC particles and sodium silicate colloid; and the particle sizes of the SiC particles in the high-temperature area thermal insulation layer, the medium-temperature area thermal insulation layer and the low-temperature area thermal insulation layer are gradually increased and the content is gradually decreased. Firstly, by optimizing the particle size and content of SiC in each heat insulation layer, it can be ensured that the positive effect is larger than the negative effect after SiC is introduced into the heat insulation layers in different temperature zones, so that the heat insulation performance of the composite material is improved, and secondly, by introducing sodium silicate colloid into the composite heat insulation material, the heat insulation performance of the composite heat insulation material under pressure is improved.
本发明涉及隔热材料领域，公开了一种多温区多层复合隔热材料及其制备方法。该复合隔热材料包括至少一层高温区隔热层、包括至少一层中温区隔热层和包括至少一层低温区隔热层；高温区隔热层、中温区隔热层和低温区隔热层均包括无机纤维基材，无机隔热粉体、SiC颗粒和硅酸钠胶体；高温区隔热层、中温区隔热层和低温区隔热层中的SiC颗粒的粒径递增且含量递减。首先，通过优化SiC在各隔热层中的粒径、含量，使得不同温区隔热层中引入SiC后都能确保正面效应大于负面效应，从而提升复合材料的隔热性能，其次，本发明通过在复合隔热材料中引入硅酸钠胶体，提升了复合隔热材料在受压下的隔热性能。
