Decorative reflective coating and preparation method thereof

Abstract

The invention provides a decorative reflective coating and a preparation method thereof. The decorative reflective coating comprises the following components in parts by weight: 5-10 parts of modifiedglass beads, 60-80 parts of acrylic resin and 5-10 parts of an emulsifier, the emulsifier being sodium dodecyl benzene sulfonate, 2-3 parts of ceramic beads, 1-2 parts of nano silicon dioxide, 1-2 parts of phenolic resin and 10-15 parts of deionized water, wherein the ratio of the modified glass beads to the ceramic beads is (2-3):1. According to the invention, the hollow glass beads and titaniumtetrabromide react to obtain the modified glass beads; the modified glass beads are coated with a layer of titanium oxide, the titanium oxide has a good thermal isolation effect, so that the coatinghas good light reflection and heat preservation properties at the same time, the added ceramic beads and the modified glass beads act together, the reflection and isolation effects are brought into full play, and the performance of the coating is improved.

Description

technical field [0001] The invention relates to the technical field of decorative reflective paint, in particular to a decorative reflective paint and a preparation method thereof. Background technique [0002] With the impact of global warming brought about by the greenhouse effect, more and more modern buildings adopt methods of heat insulation and cooling such as refrigeration, air conditioning, and spraying to optimize the living environment. The resulting building energy consumption accounts for about 30% to 40% of the total energy consumption in my country, and the research on building energy conservation has received extensive attention. Fundamentally speaking, sunlight first radiates on the exterior walls and roofs of buildings to generate heat, and the performance of reflective thermal insulation of exterior wall coatings directly affects the ability of buildings to block solar radiation. In the reflective thermal insulation exterior wall coating, hollow glass micr...

Problems solved by technology

[0003] Hollow glass microspheres are thin-walled hollow tiny spheres whose outer thin-walled main component is sodium borosilicate, which has the advantages of small thermal conductivity, low true density, high and low temperature resistance, and good thermal stability; internal inertia The gas has the unique performance of heat insulation, and is widely used in the fields of building materials and coatings. In the prior art, the coating prepared by using hollow glass microspheres alone as a filler has the characteristics of good reflective performance, but its thermal insulation effect is poor, resulting in This kind of reflective coating has poor heat insulation, and it is necessary to add a variety of thermal insulation additives, which increases the difficulty and cost of the preparation of reflective coatings.
