Heat insulating paint

Abstract

The invention discloses a heat insulating paint. The heat insulating paint comprises the following constituents in parts by weight: 3 to 12 parts of water-borne acrylic, 10 to 14 parts of propylene glycol, 8 to 11 parts of epoxy resin, 0.8 to 1.8 parts of methyl methacrylate, 23 to 36 parts of coarse whiting, 2 to 8 parts of infusorial earth, 9 to 12 parts of plant cellulose, and 3 to 7 parts of a curing agent. By adoption of the mode, the heat insulating paint not only has good heat insulating property after construction, but also is not easy to crack in the condition of large temperature difference, and is high in pollution resistance.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a thermal insulation coating. Background technique [0002] Building heat insulation materials can achieve the purpose of heat preservation and heat insulation after being compounded with the building envelope. It is a commonly used material in the implementation of building energy conservation. Building thermal insulation coatings are more and more welcomed and favored by users because of their advantages such as economy, ease of use and good thermal insulation effect. At present, the coating used as the finishing layer in the thermal insulation system for building exterior walls is a coating with ordinary emulsion as the film-forming substance. When the temperature difference between the external environment becomes large, the coating film of the finishing layer will crack, which will cause the thermal insulation layer to be damaged. cracking, which affects the service li...
