Waterproof heat insulation mortar and preparation method thereof

The invention discloses a waterproof thermal insulation mortar and a preparation method thereof. The mortar is prepared from, by weight, 30-50 parts of cement, 20-30 parts of thermal insulation base,20-30 parts of quartz sand powder, 10-30 parts of brucite powder, 10-20 parts of kaolin, 5-15 parts of nano-silica powder, 15-25 parts of light-burned magnesia, 5-10 parts of mica powder, 2-8 parts ofalum, 5-15 parts of quartz powder, 3-8 parts of hollow vitrified beads, 5-15 parts of modified jade powder, 4-10 parts of calcium carbonate, 3-10 parts of reinforcing fibers, 2-6 parts of sepiolite powder, 1-5 parts of polycarboxylic acid water reducing agent, 3-8 parts of water repellent and 60-80 parts of water. The mortar has the characteristics of high waterproof, high-efficiency heat preservation, high-efficiency heat insulation, good flame retardancy, environmental protection and the like, and can be widely used for projects such as heat preservation insulation, waterproofing and the like of interior and exterio
