Embodiment Construction

[0010] Specific embodiments of the present invention will be described in detail below.

[0011] A reflective heat-insulating paint, comprising the following components and the weight ratio of each component is:

[0012]

[0013]

[0014] A method for preparing a reflective heat-insulating coating, comprising the following steps:

[0015] First mix water, film-forming aids, wetting agents, PH regulators, dispersants, and defoamers according to the ratio, and stir until uniform; add iron red powder, iron yellow powder and ultramarine powder into the above uniform solution according to the ratio, and use a mixer Stir at a high speed of 3000r / min~5000r / min for 20min~30min to obtain a dispersion system; adjust the rotor speed of the mixer to 800r / min~1200r / min, add acrylic emulsion to the above dispersion system, and stir for 15min~ 20min; adjust the rotor speed of the mixer to 250r / min-400r / min, add thickener and anti-fungal agent, and continue stirring for 10min-15min to ...

Abstract

The invention discloses a reflective heat insulation coating and a preparation method thereof, belongs to the technical field of coatings and solves the technical problems that an existing reflective heat insulation coating is low in solar reflectance ratio and has common reflective heat insulation effect and single color. The reflective heat insulation coating comprises components in parts by weight as follows: 60-80 parts of water, 250-300 parts of an acrylic emulsion, 20-25 parts of a coalescing agent, 3-5 parts of a wetting agent, 2-5 parts of a PH regulator, 2-5 parts of a dispersing agent, 2-5 parts of a defoaming agent, 10-30 parts of iron oxide red powder, 10-30 parts of iron oxide yellow powder, 10-30 parts of ultramarine blue powder, 1-3 parts of a thickening agent and 1-3 parts of a mildew preventive. The reflective heat insulation coating has higher reflecting capacity in the infrared light band with more solar heat distribution intervals, the heat insulation effect is remarkably improved, besides, color of the reflective heat insulation coating is diversified according to a ratio of the iron oxide red powder, the iron oxide yellow powder and the ultramarine blue powder, and color demands of an outer wall of a building are met.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a reflective heat-insulating coating and a preparation method thereof. Background technique [0002] In recent years, building energy conservation has been valued by the government and the general public. By coating a layer of reflective heat-insulating coating on the surface of buildings, most of the heat in sunlight can be effectively reflected, thereby reducing the heat introduced into the room. Greatly reduce air conditioning usage. Most of the current reflective and heat-insulating coatings are aimed at white reflective and heat-insulating coatings, whose solar reflection ratio is not high, and the reflective and heat-insulating effect is average. In addition, they cannot meet people's large demand for colored reflective and heat-insulating exterior walls. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a refle...
