Abstract

The invention discloses a sunlight reflective thermal-insulation paint, and a preparation method thereof. The sunlight reflective thermal-insulation paint comprises, by weight, 35 to 50 parts of fluorocarbon resin emulsion, 5 to 15 parts of a high reflectivity pigment, 5 to 10 parts of polymer hollow micro-sphere, 5 to 10 parts of a reflective material, 5 to 15 parts of nanometer metal powder, 3 to 8 parts of nanometer silica, 0.2 to 0.5 part of a wetting dispersant, 0.4 to 0.8 part of a thickening agent, 0.2 to 0.4 part of a bactericide, 0.5 to 2.5 parts of a film forming auxiliary agent, 0.6to 1.6 parts of an antifoaming agent, and 15 to 25 parts of deionized water. The sunlight reflective thermal-insulation paint is capable of reflecting thermal energy transmission effectively, blocking heat radiation, blocking infrared heat energy, is excellent in thermal insulation performance, is low in energy consumption, is obvious in thermal insulation effect, and is long in service life; thepreparation method is simple, and is suitable for large scale production and applications.

Description

technical field [0001] The invention relates to the technical field of new materials with nanometer heat-insulating function, in particular to a sunlight-reflecting heat-insulating coating and a preparation method thereof. Background technique [0002] Although there are many types of traditional heat-insulating coatings that reflect sunlight, there are very few heat-insulating coatings that really have good heat-insulating effects; the reason is that these coatings only rely on additional materials with heat-insulating properties (such as glass beads) effect, it is difficult to obtain excellent heat insulation effect. [0003] In order to overcome these defects, heat reflective coatings have been developed in recent years. Compared with ordinary paint, this paint can reflect or scatter more infrared rays, and has a certain heat insulation effect. At present, the existing heat reflective coatings are mostly solvent-based or water-diluted coatings. [0004] A thermal insul...
