Abstract

The invention provides aqueous architectural reflective heat-insulation paint and a preparation method thereof. The aqueous architectural reflective heat-insulation paint comprises the following components according to parts by weight: 20-50 parts of high molecular synthetic emulsion, 10-20 parts of deionized water, 10-30 parts of nano material, 0.5-5 parts of dispersant, 10-30 parts of filler, 1-20 parts of pigment, 0.5-3 parts of thickening agent and 5-10 parts of other auxiliary agents. The aqueous architectural reflective heat-insulation paint has simple production technology, adopts the nano material, has excellent reflective heat-insulation performance, contains no noxious substance and does not pollute the environment. A coating manufactured by using the paint has the sunlight reflectivity (white) of 80-85%, the solar radiation heat-insulation index of more than 12 DEG C, the hemispherical emissivity of more than 0.80 and obvious reflective heat-insulation effect.

Description

technical field [0001] The invention relates to a building coating, in particular to a water-based heat-insulating coating. Background technique [0002] The world faces tight energy supplies and high prices. The energy consumption of buildings accounts for about 25% to 40% of the total energy consumption in my country. Compared with developed countries with similar climates, there is still a big gap in the thermal performance of envelope structures in most areas of my country. For regions with cold winter and hot summer and warm winter and hot summer, in summer, to prevent outdoor solar radiation and high temperature heat conduction, the heat insulation performance of the enclosure structure is required to be better; in winter, to maintain the indoor temperature, the insulation performance of the enclosure structure is required to be better. In order to achieve a better comprehensive energy-saving effect, both heat insulation and heat preservation need to be considered. ...
