Problems solved by technology

[0003] However, there are still many problems in the current research on reflective heat-insulating coatings, such as: most of the reflective heat-insulating coatings used on metal surfaces are solvent-based systems, and the environmental protection effect is poor; the cost of applying multi-layer coatings is high and the reflection efficiency is relatively low. Poor, resulting in poor heat insulation effect of the coating, etc.

preparation example Construction

[0028] The present invention also provides a method for preparing the paint. First, add additives including wetting agent, dispersant, antifreeze, and preservative into water and stir at a low speed for 10 to 15 minutes;

[0029] Next, add pigments and fillers and functional fillers, stir at high speed for 15 to 20 minutes, add an appropriate amount of defoamer and thickener to pre-mix the ingredients during the stirring process, and grind the uniformly mixed pigments and fillers for 10 to 20 minutes;

[0030] Then, stir the ground slurry at a low speed, add the emulsion mixed with film-forming aids and plasticizers and mix evenly;

[0031] Finally, add a defoamer and a pH regulator, and add a thickener according to the required viscosity, stir well and filter to obtain a finished product.

[0032] In the above coatings, in order to better mix the components and achieve better physical and chemical properties,

[0033] Preferably, when hollow ceramic microspheres are used as ...

Abstract

The invention provides light reflection heat insulation coating. The light reflection heat insulation coating is characterized by comprising the following concrete components: emulsion, pigment filler, functional filler, auxiliaries and water, wherein the emulsion is mixed solution containing waterborne polyurethane resin and waterborne polytetrafluoroethylene resin; the pigment filler comprises titanium dioxide and talcum powder; the functional filler comprises a hollow ceramic microbead material and infrared ceramic powder; and the auxiliaries comprise a dispersing agent, an antifreezing agent, a thickening agent, a wetting agent, a defoaming agent, a coalescing agent, a preservative, a pH regulator and a plasticizer. The invention also provides a preparation method of the light reflection heat insulation coating. The light reflection heat insulation coating has the advantages that heat insulation performance of the light reflection heat insulation coating is improved in a waterborne coating system, the light reflection heat insulation coating also has multiple functions in self-cleaning, heat insulation, weather resistance and decoration, and the effects of saving energy and protecting the environment are achieved.

Description

technical field [0001] The invention relates to the technical field of architectural exterior wall coatings, in particular to a composition of light-reflecting coatings and a preparation method thereof. Background technique [0002] Building exterior wall paint is an important decorative material in modern construction operations. It can not only beautify the environment and give people beautiful enjoyment, but also play a good role in protecting buildings. In recent years, architectural coatings at home and abroad have made great progress in terms of variety, scale application, quality level and research level. Judging from the current development momentum, the architectural coatings consumption market will maintain a relatively high growth rate in the next few years , the prospect is broad, and the functional building thermal insulation coating will become one of the important development directions in the future. [0003] However, there are still many problems in the cur...
