Problems solved by technology

However, the current coatings often have shortcomings such as water resistance, weather resistance, pollution resistance and poor mechanical properties.
[0004] At the same time, when exterior wall coatings are used in some high-design buildings, special visual effects are required from the appearance, such as shiny effects or discoloration effects, etc. gradually decrease until it disappears

Embodiment 1

[0017] The invention provides a high-strength exterior wall paint with bright bead effect. Calculated in parts by weight, the proportions of each component are: 25 parts of acrylic emulsion, 25 parts of pure acrylic elastic emulsion, 5 parts of titanium dioxide, 5 parts of kaolin, and propylene glycol 8 parts, 7 parts of talcum powder, 10 parts of glaze powder, 27 parts of lignocellulose, 27 parts of glass fiber, 120 parts of deionized water, 0.5 parts of thickener, 3.5 parts of dispersant, 3.1 parts of defoamer, wetting agent 0.25 parts, 1 part antifungal agent. Titanium dioxide is composed of rutile titanium dioxide and anatase titanium dioxide, which account for 80% of rutile titanium dioxide and 20% of anatase titanium dioxide. The average powder diameter of rutile titanium dioxide is 0.10 μm, and the average powder diameter of anatase titanium dioxide is 0.30 μm. The glaze powder is a low-temperature feldspar glaze powder with a size of 75 μm and a molding temperature of...

Abstract

The invention belongs to the field of coatings, and provides a high-strength outer wall coating with a bright bead effect. The high-strength outer wall coating consists of the following components: crylic acid emulsion, pure-acrylic elastic emulsion, titanium dioxide, kaolin, propylene glycol, talcum powder, glaze powder, lignocelluloses, glass fiber, deionized water, a thickening agent, a dispersing agent, a defoaming agent, a moistening agent and an anti-mold agent. The invention further provides a preparation method of the high-strength outer wall coating. Compared with the prior art, a finished product prepared by using the preparation method has the beneficial effects of being good in plasticity, good in cracking resistance, good in water, weather, pollution and wearing resistance, good in anti-aging property, and convenient and rapid in coating.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a high-strength exterior wall coating with a bright bead effect and a preparation method. Background technique [0002] In industrialized countries such as Europe and the United States, 90% of the exterior walls of buildings are finished with high-performance coatings; while the exterior walls of our country are still far below this level, and most of them use hard surface materials (bricks, granite, ceramic tiles, etc.) , curtain wall and stainless steel panels). These hard facing materials are not only expensive, but also have the potential safety hazard of being damaged and falling. At present, the rapid development of China's real estate industry provides a huge market for exterior wall coatings. [0003] Exterior wall coatings mainly play the role of decorating and protecting the exterior walls. The most important properties are mainly reflected in appearance, water resistance, weath...
