Abstract

The invention discloses a low thermal conductivity wall thermal insulation coating and its preparation method and relates to the technical field of building materials. The low thermal conductivity wall thermal insulation coating is prepared from 75 to 85 parts of polyamide resin, 55 to 65 parts of epoxy resin, 45 to 55 parts of modified hollow ceramic beads, 35 to 40 parts of silica airgel, 30 to 33 parts of talc powder, 25 to 27 parts of glass wool, 20 to 23 parts of an inorganic additive, 15 to 20 parts of an infrared reflective pigment, 15 to 18 parts of aids and 85 to 95 parts of deionized water. The low thermal conductivity wall thermal insulation coating can form a low thermal conductivity protection layer on the wall after curing and has good corrosion resistance, cohesiveness and compressive strength.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a wall thermal insulation coating with low thermal conductivity and a preparation method thereof. Background technique [0002] At present, thermal insulation coatings are widely used in various fields of the national economy. However, general thermal insulation coatings are poor in reducing convection and radiation heat transfer, and the thermal insulation layer is thick, not resistant to vibration, high water absorption, and long service life. Short, poor anti-corrosion ability, the most widely used barrier type thermal insulation coating is composite silicate thermal insulation coating, which has been widely used in practical applications. However, the coating still has defects caused by its own material structure, such as long drying period, construction conditions are greatly affected by seasons and climates, poor impact resistance, large drying shrinkage, hig...
