Abstract

The invention discloses a heat-insulating coating for outer walls. The heat-insulating coating is prepared from raw materials in parts by weight as follows: 15-30 parts of hollow ceramic microspheres, 10-20 parts of diatomite, 10-25 parts of coarse whiting, 8-18 parts of talc powder, 15-30 parts of muscovite, 5-12 parts of titanium dioxide, 3-10 parts of zinc oxide, 2-10 parts of an elastic acrylic emulsion, 1-8 parts of hydroxyl cellulose, 1-5 parts of an aid and 80-150 parts of water. The prepared coating can effectively reduce temperatures of surfaces of the outer walls of buildings and indoor temperatures, has the good heat-insulating effect, is high in bonding strength to wall bodies, greatly improves heat-insulating, waterproof and corrosion-resistant functions of the wall bodies, and prolongs service lives of the wall bodies.

Description

technical field [0001] The invention relates to a coating, in particular to an exterior wall heat-insulating coating, which belongs to the technical field of building materials. Background technique [0002] With the increasingly acute energy problems, people pay more and more attention to energy saving and emission reduction while developing new energy sources. In the field of construction, thermal insulation coatings with advantages such as economy, environmental protection, and energy saving are used more and more widely as thermal insulation materials on the surface of buildings in the construction industry. Building exterior wall thermal insulation coatings are divided into three types according to their thermal insulation mechanism: 1) barrier coatings that increase the thermal resistance of the external wall to block and reduce heat conduction and heat convection; 2) reflective coatings that reflect visible light and infrared light to reduce the temperature of the ext...
