Problems solved by technology

[0003] However, there are few varieties of commercialized exterior wall heat insulation coatings at present, and most of them use one or two of the three heat insulation methods of reflective heat insulation, radiation heat insulation, and barrier heat insulation. Although they have a certain heat insulation effect , but the overall performance is poor, and it can only exert obvious heat insulation effect in a specific thermal environment

Abstract

The invention relates to a reflection, radiation and blocking type external wall heat insulation coating. The heat insulation coating is based on a reflection heat insulation coating and a blocking heat insulation coating, wherein high-reflectance stuffing, hollow insulating stuffing and thermal radiation stuffing are preferably selected, controlled in particle size, and uniformly dispersed in a water-based binding agent. In order to reduce the damage to a coating film caused by environmental factors such as sunlight irradiation during the use of the external wall heat insulation coating, an organic binding agent and an inorganic binding agent are mixed for use, a nano modifying agent is also added to improve the durability of the coating film and hence to reduce the degradation of the external wall heat insulation coating in heat-insulating property. The heat insulation coating provided by the invention has three heat insulation manners, namely reflection heat insulation, radiation heat insulation and blocking heat insulation, thereby having prominent insulating effect and excellent comprehensive performance.

Description

technical field [0001] The invention relates to a heat-insulating coating for exterior walls, in particular to a heat-insulating coating for reflecting radiation and blocking exterior walls. Background technique [0002] With the increasingly severe energy crisis, energy conservation, emission reduction and improvement of energy efficiency have become one of the important goals of the development of science and technology. As a technology widely used in various fields of society, coating technology is also facing new challenges and opportunities, especially the thermal insulation coating for building exterior walls, which is not only manufactured with green environmental protection technology itself, but also by changing the heat transfer of buildings. Direction, reflect or radiate external heat energy such as solar radiation energy back into the atmosphere, and reduce the conduction of heat energy inside the building to the outside world, thereby reducing the building's ope...
