Spraying technological method for manufacturing building external wall with rock color wall paintings

Abstract

The invention discloses a spraying technological method for manufacturing a building external wall with rock color wall paintings, and belongs to the technical field of rock color painting building external wall decoration. The method includes the steps that according to the technical characteristics of the rock color paintings, color layer analysis is performed on the wall paintings, and a chromatography construction drawing and a color layer graph template are manufactured; the color layer graph template and the spraying sequence of corresponding color layers are indicated on the chromatography construction drawing; in accordance with the standard and requirements of a spraying construction technology of the building external wall, and a rock color painting material is mixed with an external wall coating medium so that the construction requirements can be met; according to a construction procedure diagram, the graph template is fixed to a construction interface, the peripheral region of the template is protected, pollution caused in the spraying process is prevented, and when the template is replaced to spray the next color layer, the effect that a formed film on the surface of the previous color layer is basically dry should be guaranteed; and after pictures are sprayed and dried thoroughly, the surface of each wall painting is polished, rock color material particles not bonded are removed, dust is blown dry, and transparent protective topcoat is brushed.

Description

technical field [0001] The invention relates to a spraying process for making rock color murals on building exterior walls, and belongs to the technical field of rock color painting building exterior wall decoration. Background technique [0002] Rock color painting refers to works that grind colorful rocks into coarse and fine particles, blend with colloid-based media materials, and draw on paper, cloth, wood boards, walls, glass, plastic, metal and other media. [0003] Rock color painting materials mainly include: natural ore particles of different thicknesses, natural colored sandstone, natural soil, etc.; commonly used auxiliary materials include various metal foils, animal and plant fibers, etc.; commonly used binders include animal gelatin or white latex. [0004] The technical feature of rock color painting is to present the shape of the picture by flat painting with a brush or a brush. Due to the different thickness and weight of natural rock color, the color is gen...

Problems solved by technology

[0005] Rock color paintings are rich in color, rich in texture, and strong in visual effects, and are suitable for decoration in large public spaces. However, the drawing process is complicated and accidental, and it is difficult to standardize production and reproduction; manual painting has restrictions on the particle size of materials, and the efficiency is low. It has high requirements on construction conditions and environment; the adhesive medium is only suitable for general painting creation, does not meet the weather resistance standards in outdoor environments, and cannot adapt to the new needs of public art decoration in the development of modern society
