The invention relates to the technical field of thermal insulation materials, in particular to a phase change vacuum ceramic thermal insulation material. The phase-change vacuum ceramic thermal insulation material is prepared by mixing the following raw materials in percentage by weight: 15%-40% of acrylic emulsion, 20%-60% of gypsum powder, 15%-70% of ceramic microbeads, 15%-85% of fine sand, 1%-40% of a phase-change material, 15%-55% of fly ash, 3%-45% of aerogel, 1%-30% of an auxiliary agent and a proper amount of water. The invention has the following beneficial effects: 1, the density is very small, and the specific gravity is about 0.5 and is only half of the density of water; 2, the heat conductivity coefficient is very low; the equivalent heat conductivity coefficient is 0.00206; 3, the construction is simple, the mortar can be sprayed and brushed, and the mortar with the thickness of 2-6mm can replace the traditional thermal insulation mortar with the thickness of 15cm; 4, the firmness is strong, and the powder or the falling is not easy to occur; and 5, the product has the advantages of high light and heat reflectivity, low heat transfer coefficient, high equivalent thermal resistivity and excellent heat conductivity coefficient.
本发明涉及保温隔热材料技术领域，具体是指相变真空陶瓷保温隔热材料。相变真空陶瓷保温隔热材料，由以下重量配比的原料混合而成：丙烯酸乳液15％～40％、石膏粉20％～60％、陶瓷微珠15％～70％、细砂15％～85％、相变材料1％～40％、粉煤灰15％～55％、气凝胶3％～45％、助剂1％～30％和水适量。本发明的有益效果是：1.密度非常小，比重在0.5左右，只是水密度的一半；2.导热系数非常低。当量导热系数是0.00206；3.施工简单，可喷可刷，一般厚度2～6㎜厚即可代替传统保温砂浆15cm厚的效果；4.牢固度强，不易粉化或脱落；5.本产品具有对光热高反射率、传热系数低、当量热阻率高，导热系数非常出色。
