The invention discloses a heat-preservation material which is prepared from the following components in percentage by mass: 25-40% of expanded perlite, 20-30% of cement, 5-10% of construction gypsum, 5-10% of sepiolite fiber, 10-15 parts of a high-velocity agent, 1-2% of redispersible adhesive powder, 1-3% of hydroxypropyl methyl cellulose and 1-2% of water repellent, wherein the stacking density of the mixed base materials is 240-280kg/m<3>, and the weight ratio of the base materials to water is 1:(1.2-1.3) when the heat-preservation material is used. The high-velocity agent used in the heat-preservation material is an inorganic high-velocity agent. The water repellent used in the heat-preservation material is organic silicon water repellent.
