Abstract

The invention discloses reflective insulation building paint. The reflective insulation building paint is prepared from the following raw materials in parts by weight: 72-82 parts of styrene-acrylic emulsion, 24-27 parts of active powder, 8-10 parts of polyacrylonitrile-based carbon fibers, 2-3 parts of chromic chloride, 10-15 parts of titanium dioxide, 2-3 parts of vanadium pentoxide, 1-1.5 parts of sodium dodecyl benzene sulfonate, 2-3 parts of dimethyl silicone oil and 0.8-1.2 parts of triethylene tetraamine, wherein the active powder consists of pyrophyllite with a grain size of 500-800mesh and sepiolite in a ratio of 1 to 2. The aqueous paint for a building exterior wall disclosed by the invention has good reflective insulation effects; meanwhile, the optimized formula has relatively high bonding strength and relatively high high-temperature resistance.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, more specifically, to a reflective heat-insulating architectural paint and a preparation method thereof. Background technique [0002] Reflective heat-insulating coatings are mainly used in heat-insulating occasions in the field of construction engineering, that is, the use of high-reflective heat-insulating coatings on the surface of the outer envelope can reduce the absorption of solar radiant heat by buildings and prevent the surface of buildings from absorbing sunlight. The temperature rise caused by radiation reduces the heat transfer into the room. In the past, it was mainly researched on the application on the roof to reduce the temperature rise and protect the roof waterproof material. In recent years, due to the emergence of new high-efficiency reflective material glass hollow microspheres abroad and the promotion of products, the application of this kind of coatings in the ex...
