Problems solved by technology

[0004] Relevant studies have shown that when fillers such as hollow glass beads are used in reflective thermal insulation coatings, their dosage must exceed a certain threshold, otherwise the thermal insulation effect will not be good
However, the mechanical properties of the coating at this time will be reduced due to the addition of a large amount of hollow fillers, making it difficult to achieve a balance between heat insulation effect and mechanical properties in some applications.

Abstract

The invention provides a reflecting heat-insulating coating and a preparation method thereof. The reflecting heat-insulating coating is characterized by comprising a base coating and an imaging layer;the base coating is a continuous coating formed by subjecting reflecting heat-insulating paint including hollow glass beads and hollow polymer beads to drying or curing and filming; the imaging layercomposed of hollow glass beads partially embedded in the top of the base coating and subjected to surface modification, and forms obvious raised point structures. Overall coating reflecting ratio isincreased such that surface heat resistance of the coating is improved, and the effects such as heat transfer between the surface of the coating and air are enhanced; cooling effect of the coating obtained is improved.

Description

technical field [0001] The invention belongs to the technical field of reflective heat-insulating coatings, and in particular relates to a reflective heat-insulating coating and a preparation method thereof. Background technique [0002] The Sun continuously moves at about 1.77×10 17 The speed of J / s radiates energy to the surface of the earth, providing energy for human beings to survive. However, strong solar radiation can also cause negative effects such as excessive temperature, which need to be adjusted and controlled by measures. As an important means to control the influence of solar radiation, the technology of reflective heat-insulating coatings has attracted more attention. Since the 1980s, research on various coatings that reduce the temperature of the coated object under solar radiation has been active. At present, reflective heat-insulating coatings have been successfully used in aerospace, construction, petrochemical, military, industrial and other fields, a...
