preparation example Construction

[0016] The preparation method of the colored reflective and heat-insulating coating is to prepare the color paste first, and then carry out color matching to produce the colored reflective and heat-insulating coating.

[0017] The gray reflective heat-insulating paint with a lightness of 50, compared with ordinary paints, has a reflectivity increased by 17%, and can reduce the surface temperature of buildings by 20°C.

[0018] According to the length of the wavelength, sunlight can be divided into ultraviolet light, visible light and infrared light. The wavelength of ultraviolet light is less than 400nm, accounting for about 5% of the total energy of the sun. The wavelength of visible light is 400nm-760nm, which accounts for about 45% of the total energy of the sun. The wavelength of infrared rays is greater than 760nm, accounting for about 50% of the total energy of the sun. It can be seen that solar energy is mainly concentrated in the visible light region and the infrared...

Abstract

The invention discloses a colored reflection heat insulation coating, comprising acrylic acid emulsion, titanium dioxide, infrared reflection pigment, calcium carbonate powder, powdered steatile, kaolin powder, dispersant, wetting agent, antifoaming agent, thickening agent, film forming auxiliary agent, and antiseptic. The heat insulation principle of the reflection heat insulation coating is high reflectivity, thus the heat of solar radiation can be effectively reduced. According to the invention, the colored reflection heat insulation coating disclosed herein is used for coating the exterior walls of buildings, can reduce the surface temperature of the buildings by 10-20 DEG C, thus the energy consumption of air conditioning is saved; the colored reflection heat insulation coating can be used in hot-in-summer and warm-in-winter area hot-in-summer and cold-in-winter area and the like, thus the effects of heat preservation and heat insulation are achieved; the colored reflection heat insulation coating has excellent energy saving effect; and compared with the prior art, the colored reflection heat insulation coating has remarkable substantial characteristics and significant progress.

Description

technical field [0001] The invention relates to the technical field of environmental protection coatings for exterior walls of building construction, in particular to a colored reflective heat-insulating coating, and in particular to the mass percentage of the coating composition. Background technique [0002] Building energy conservation is one of the key points of my country's energy conservation work, and external wall insulation has become the main product of building energy conservation. For areas where thermal insulation is the main focus of thermal design, such as severe cold areas and cold areas, external wall insulation is not only reasonable, but also applicable, and has developed rapidly. For hot summer and warm winter regions where thermal design generally only considers heat insulation, or hot summer and cold winter regions where heat insulation is the main consideration in thermal design, there is room for further improvement of some current external wall ...
