Formula and preparation method of coating suitable for water seepage wall of basement

Abstract

The invention discloses a formula of a coating suitable for a water seepage wall of a basement. The coating is prepared from the materials in percentage by weight: 40% of cement, 28% of slaked lime powder, 15% of quartz sand, 8% of fine aggregate, 7% of polymer powder, 1% of anti-crack fiber and 1% of superhydrophobic silicon resin powder. The formula disclosed by the invention is scientific and reasonable in component proportion, capable of meeting various requirements of a coating for an internal wall and good in construction quality. The coating can be used for smearing the surface of a wall body by using a spray method and a scraping method, so that a decorative surface of which the thickness is controllable and uniform can be obtained. The coating disclosed by the invention has strong adaptability on the water seepage wall of the basement, has the advantages of water resistance, waterproofness, strong bonding power and the like and generally reaches the service life period of more than ten years. The invention further provides a preparation method of the coating.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a paint formulation and preparation method suitable for water seepage walls in basements. Background technique [0002] Architectural coatings are materials that use different construction techniques to paint various base materials of buildings, such as walls, columns, structural ceilings, etc., to form a complete and tough protective film. Architectural coatings are also the direct manifestation of architectural decorative surfaces. Different architectural coatings and colors produce different architectural decorative effects. At present, the materials used in architectural decoration at home and abroad mainly include: decorative stone, decorative panels, architectural coatings, etc. Among them, architectural coatings have bright colors, rich shapes, and good decorative effects; excellent performance, diverse functions, and good protection effects; conv...

Problems solved by technology

[0003] In recent years, with the rapid development of China's urbanization, the continuous improvement of my country's economic strength and people's living standards, the owners' continuous emphasis on project quality, the continuous development of construction technology, and the continuous expansion of various high, large and deep projects, Especially in basements in areas with abundant groundwater, the problem of water seepage on external walls cannot be completely solved. Therefore, for basement water seepage walls, traditional coatings tend to soften, peel and fall off quickly after being used on water seepage walls. It can be seen that traditional architectural coatings can no longer meet the construction and use requirements of water seepage walls, let alone meet people's requirements for aesthetics and durability of modern buildings. Therefore, the construction industry poses new challenges to the development of architectural coatings. At the same time It also provides unprecedented development opportunities for architectural coatings products
