Problems solved by technology

[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

specific Embodiment approach

[0037] The present invention adds a special heat-insulating powder to the provided sunlight-reflecting heat-insulating coating, and coats the pigment in the coating, thereby achieving the following ideal effects:

[0038] 1. Special heat insulation powder, which significantly improves the heat insulation effect;

[0039] 2. As we all know, dark-colored objects are easy to absorb heat; after coating the pigment, the heat can be reflected, which can reduce the heat-absorbing effect of dark-colored objects, so as to achieve the purpose of heat insulation.

[0040] The auxiliary agents include preservatives, bactericides, dispersants, leveling agents, defoamers, film-forming aids, thickeners and antifreezes in sequence, and the ratio between them is recommended to be 1:1:3:2 :3:6:4:10.

[0041] The porous mineral particles are diatomite, pumice, expanded perlite, sepiolite, zeolite at least one or a mixture of two or more in any proportion; it can be a crushed natural mineral or ...

Abstract

The invention relates to a sun-reflection heat-insulation paint and a manufacturing method thereof. The invention aims to provide a paint with favorable heat-insulation property. The technical scheme is as follows: the sun-reflection heat-insulation paint comprises a water-based resin, assistants, titanium white, heat-insulation powder and a far-infrared powder composite pigment, wherein the water-based resin is a pure acrylic emulsion or fluorocarbon resin emulsion or silicone acrylate resin emulsion; and the assistants comprise a preservative, a bactericide, a dispersing agent, a leveling agent, a defoaming agent, a film formation assistant, a thickener and an antifreezing agent. The manufacturing method comprises the following steps: (a) proportionally and uniformly mixing porous mineral particles, silane coupling agent, dispersing agent, deionized water and anhydrous ethanol; (b) proportionally and uniformly mixing far-infrared powder, anti-phase-separating agent, water and anhydrous ethanol; (c) proportionally and uniformly mixing the liquids formed in the steps (a) and (b), and aging to obtain a gel; and (d) drying and holding the gel to obtain the composite powder.

Description

technical field [0001] The invention relates to a coating and a manufacturing method thereof, in particular to a heat-insulating coating for reflecting sunlight and a manufacturing 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sunlight-reflecting heat-insulating coating and its production method. The coating should have good heat-insulating performance, and has the characteristics of easy-to-obtain raw materials, convenient manufacture and low cost. [0004] The technical scheme provided by the i...
