Problems solved by technology

[0005] However, due to the high density of quartz sand (1.6-1.7t / m 3 ), generally 2.2 times or even higher than that of water, which makes the above-mentioned sand-in-water multi-color paint prone to layering and segregation in the process of preparation and storage, and the density of the paint layer after construction is high, and the effect of reflective heat insulation is not ideal

Abstract

The invention discloses reflection-type light sand-in-water multi-color paint, belongs to the technical field of building exterior wall paint, and aims to solve problems in the prior art that the sand-in-water multi-color paint is large in density, poor in laminarity resistance, and poor in reflective insulation effect. A key point of a technical scheme of the sand-in-water multi-color paint is that raw materials comprise at least two types of different colors of sintering light color sand, environment-friendly acrylic emulsion, protective glue, a defoaming agent, propylene glycol, a preservative and a thickening agent, wherein the density of the sintering light color sand is 900-1000 kg / m<3>. The reflection-type light sand-in-water multi-color paint has the advantages of good laminarity resistance, good reflective insulation effect, lasting color and washing-out resistance. Another purpose of the invention is to provide a preparation method for the above reflection-type light sand-in-water multi-color paint. The preparation method is simple in process, and the sand-in-water multi-color paint prepared by the preparation method is adequate in texture, good in decorative effect, andexcellent in reflective insulation performance.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall paint and its preparation, and more specifically relates to a reflective light-weight sand-in-water multi-color paint and a preparation method thereof. Background technique [0002] Natural granite has a limited variety of patterns and colors, and the cost is extremely high. The dry-hanging load of the stone is too heavy, and there is a hidden danger of falling off over time. Natural granite is widely used in construction, but the mining and application of natural stone materials will lead to social and public problems such as resource waste and exhaustion and climate warming. With the continuous development of my country's requirements for building energy conservation, buildings must be externally insulated to reduce building energy consumption. It is not only difficult to construct the external wall of the building with external thermal insulation and then decorate it with stone,...
