The invention discloses a Na-based rare earth composite heat insulation coating and a preparation method thereof, and belongs to the technical field of building construction materials. The Na-based rare earth composite heat insulation coating is characterized by being prepared from the following materials in parts by weight: 30-100 parts of tap water, 1-5 parts of a penetrant, 5-30 parts of glass wool, 5-30 parts of aluminum silicate wool, 10-50 parts of diatomite, 10-50 parts of silica fume, 0.5-1 part of rare earth, 3-5 parts of Na-based earth, 5-30 parts of floating beads, 1-5 parts of an expanding agent, 0.001-0.005 part of high temperature glue, and 5-40 parts of perlite. Compared with the prior art, the Na-based rare earth composite heat insulation coating is wide in using temeprature range, suitable for long-term use, low in aging possibility, free from deterioration, non-toxic, odorless, and long in service life, and has the outstanding substantial characteristics and significant progress that the size is small, the heat conductivity coefficient is low, and the effects of cold insulation, heat insulation, shock resistance and sound absorption are good.
