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...
