Anti-ultraviolet external wall paint and preparation method thereof

Abstract

The invention relates to the technical field of building materials and in particular relates to anti-ultraviolet and heat-insulated external wall paint and a preparation method thereof. The external wall paint comprises the following raw materials in percentage by weight: 10%-15% of de-ionized water, 0.1%-0.15% of a preservative, 1%-1.5% of a dispersant, 0.2%-0.5% of a wetting agent, 16%-20% of rutile titanium dioxide, 6%-8% of heavy calcium carbonate, 7%-10% of calcined kaolin, 5%-9% of wollastonite, 6%-8% of magnesium oxide, 30%-35% of acrylic acid modified emulsion, 0.3%-0.5% of an anti-settling agent, 3%-5% of glass beads, 0.9%-1.05% of an anti-yellowing agent, 2%-5% of a film-forming assistant, 0.2%-0.5% of a flatting agent and 0.25%-0.5% of a thickener. According to the external wall paint, the performance of reflection and heat insulation on light and heat is improved; outdoor and indoor heat bridges are disconnected for preventing outdoor and indoor heat alternation, so that the indoor heat loss is reduced, the energy resources are saved, the heat loss is reduced, the yellowing resistance is enhanced, and the heat insulation function is improved; the temperature of the external wall paint is 2.46 DEG C lower than the box indoor temperature of general paint, and the heat insulation effect is remarkable.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to an anti-ultraviolet exterior wall paint and a preparation method thereof. Background technique [0002] In this society full of high-rise buildings, the material conditions of life are getting better and better, the desire and pursuit of spiritual aspects are getting stronger and stronger, and the demand for the pursuit of nature is getting bigger and bigger, so the impact on visual colors is getting bigger and bigger. more intense. Therefore, the colorful coatings used on high-rise buildings are becoming more and more gorgeous. But the sun is the main killer of bright colors. To be precise, the ultraviolet rays in the sun are the executioners who destroy the colors in the paint. He can destroy and decompose the colors in the paint, make it fade, and destroy the film-forming substances of the paint Let the paint age, thereby reducing the life of the paint, and making the paint ...

But the sun is the main killer of bright colors. To be precise, the ultraviolet rays in the sun are the executioners who destroy the colors in the paint. He can destroy and decompose the colors in the paint, make it fade, and destroy the film-forming substances of the paint Let the paint age, thereby reducing the life of the paint, and making the paint lose its protective effect on the building wall
