Problems solved by technology

Although various types of imitation brick coatings have been developed rapidly, after visiting many imitation brick engineering projects, there are still many hidden dangers in construction. (1) The adhesion of the coating film is poor. Destroying the coating, causing peeling, and then reworking or drawing lines, which brings great trouble to the construction
(2) The pointing black paint used can only resist alkali or improve adhesion, and often does not have the functions of UV resistance and anti-aging, resulting in pulverization and water seepage of imitation brick joints after sunlight and long-term wind and rain Phenomenon

Abstract

The invention discloses special joint pointing black paint for an outer wall imitation brick process and a preparation method of the black paint. The special joint pointing black paint comprises, in weight percentage, 35-40% of acrylic emulsion, 2-3% of silica solution, 2-3% of titanium dioxide, 5-10% of kaolin, 5-10% of calcium carbonate, 0.8-1% of environment-friendly solvents, 0.2-3% of film coalescing aid, 0.1-0.2% of moistening agents, 0.5-0.8% of dispersing agents, 0.3-0.5% of cellulose, 0.1-0.3% of defoaming agents, 0.1-0.3% of preservative, 0.2-3% of thickening agents, 3-5% of carbon black color paste and 28-35% of water. The special joint pointing black paint is green and environmentally friendly, alkali resistance of the black paint is normal within 144h, ageing resistance of the black paint is normal within 600h, and the black paint has grade-1 adhesive force and is high in textured-paper-resistant efficiency.

Description

technical field [0001] The invention relates to the field of paints, in particular to a special pointing black paint for exterior wall imitation brick technology and a preparation method thereof. Background technique [0002] In recent years, the application of imitation brick coatings in the real estate market and engineering projects has been on the rise. In most provinces in China, the state has issued relevant policies to mandate external wall insulation systems, but because the external insulation base has a strong load-bearing Requirements, ceramic tiles or marble loads are relatively heavy, there is no way to meet the basic requirements of external insulation, especially high-rise buildings have the risk of falling off, so the rapid development of imitation brick coatings, including real stone paint imitation bricks, texture paint imitation bricks, colorful paint Imitation brick, elastic paint imitation brick and many other types. Although various types of imitation ...
