The invention provides a waterproof 
thermal insulation rheological material and a preparation method thereof. The waterproof 
thermal insulation rheological material is prepared from 240 to 350 parts by 
mass of latex-containing solution, 50 to 120 parts by 
mass of 
organosilicon waterproofing agent, 50 to 100 parts by 
mass of 
aerogel powder, 50 to 150 parts by mass of hollow glass-bead, 150 to 200 parts by mass of 
pigment filler, 150 to 200 parts by mass of 
solvent and 40 to 100 parts by mass of various aids. The waterproof 
thermal insulation rheological material is dried to form a waterproof 
insulation layer; the waterproof 
insulation layer has the characteristics of good elasticity, high 
bonding strength, water-repellent and self-cleaning property, obvious waterproof and anti-seepage effect, heat and 
frost resistance, UV 
irradiation resistance, 
antibody aging resistance, good extension performance, thermal insulation, no 
pollution and the like; in addition, one-time construction can achieve two requirements of 
water resistance and heat insulation; meanwhile, the waterproof thermal insulation rheological material can improve the waterproof and thermal insulation properties of building roofs, 
metal plates, tiles, decorative tiles and the like.
