Technical Field

The invention relates to a method for decorating the surface of an object, in particular to a method for manufacturing an anti-crack texture sandwich coating and a coating on the surface of an object such as a building.

Background

The wall surface coating is used for decorating and protecting the building wall surface, so that the building wall surface is attractive and tidy, and meanwhile, the wall surface coating can also play a role in protecting the building wall surface and prolonging the service life of the building wall surface. In the specific technical field, the development of various binder film-forming technologies makes great progress on the performance of the coating, and the development of emulsion preparation technology is particularly important. The existing coating materials form a component system with binders, fillers, pigments, additives and solvents (such as water). In order to embody the environmental protection performance of the coating, inorganic binders (such as silicates) and various aqueous emulsions are commonly used as film-forming materials for the coating. In order to reduce the content of harmful substances such as VOC, benzene, formaldehyde and the like, water is generally used as a solvent.

Throughout the development process of the architectural coating technology, the development of the coating technology goes through the process from simple color decoration and functional protection to balanced development of color and functional protection, and the wall coating is developed towards the trend of rich and colorful, fashionable, healthy, environment-friendly and functional besides the decoration and protection functions of the wall coating.

The texture coating is mainly characterized in that different shapes and patterns are formed on a wall by using special tools, so that the space is more three-dimensional, real, attractive and elegant. The texture paint shows a unique space visual angle by the infinitely variable three-dimensional texture and the multi-choice individual collocation, and meets the overall decoration style by individual creation, so that the texture paint shows the own unique style in decoration, and the texture paint can also be called as artistic paint. However, the texture formed on the surface of the wall body by the texture coating is manual texture, so that a standardized and large-scale texture effect cannot be formed, and the requirement of uniform and uniform texture cannot be met when the texture coating is used in a large area.

In order to show the coating texture of the coating, the particle size of the filler in the coating component needs to be enlarged, generally the particle size range of sand, and various manual-plastering coating textures and spraying textures are formed by adopting the methods of manual plastering and spray gun spraying. In order to improve the crack resistance of the coating, a high-elasticity binder is generally used as a film-forming material to improve the ductility of the coating, or suitable short fibers are added to the components such as the binder, the filler, the pigment, the additive and the solvent (such as water) to improve the crack resistance of the coating, so as to meet the crack resistance requirement of the coating. Similar to the texture coatings described above, this texture also does not provide a standardized, scaled texture effect.

In the other technology aspect of making textures on the surface of a wall body, one is to make textures in a coating on the surface of a building by adopting a special tool. For example, chinese patents CN205577286U and CN205444747U both adopt a scraper and a spatula to scrape and coat the surface of the coating to form texture, the texture coating has high requirements on operators, the texture of the surface of the same building is easily different, and the crack resistance is poor. The other way is to form texture in a way of sticking wallpaper, wall cloth or a wallpaper imitation decorative layer, the rough surface of the wallpaper, wall cloth or decorative layer is used as the texture, and then coating is coated on the surface, the wallpaper in the texture coating is easy to peel off, and when the adjacent wallpapers are butted, gaps are very obvious, so that the texture can not be smoothly transited. For example, in chinese patent CN103758307A, the base material components are first pressed and molded in a mold with a wallpaper texture to produce a decorative surface with texture, and then an ultraviolet-resistant coating is sprayed on the texture surface, and when in use, the produced wallpaper texture-imitating layer is adhered to a wall.

Coatings with both crack resistance and texture have become a popular research direction in the coating field except for environmental protection performance, but related technologies are not yet available.

The method for manufacturing the impregnation coating composite anti-crack texture sandwich coating on the surface of the object or the method for manufacturing the texture has the following beneficial effects that:

1) the impregnating coating paint is coated on the surface of an object, has enough adhesive force with the surface of the object, and the whole coating finish surface is firm and reliable.

2) The coating infiltrates, permeates and fills into the meshes of the three-dimensional interpenetrating network structure of the fiber texture network sandwich, so that the fibers of the fiber texture network sandwich and the infiltrated coating have occlusion and bonding effects, and meanwhile, because the meshes of the three-dimensional interpenetrating network structure are three-dimensionally distributed and are communicated with each other, and the infiltration, permeation and filling of the coating in the meshes are also in a three-dimensional form, the coating and the fiber texture network sandwich can be more tightly combined, so that compared with the texture manufacturing of wallpaper, the coating has obviously higher stripping resistance.

3) The sandwich structure is formed, the fiber texture network sandwich is positioned between the impregnating coating materials, the thickness of the fiber texture network sandwich is more than or equal to the sum of the thicknesses of the first coating and the second coating, after the second coating is coated on the surface of the fiber texture network sandwich, the thickness of the surface of the fiber is increased, and the second coating on the surface of the mesh is sunken in the curing process, so that the texture of the fiber texture network sandwich is presented, therefore, the sandwich structure has the advantage of controllable texture, the fiber texture network sandwich can be manufactured in a standardized and large-scale production manner, and the consistency of the texture is ensured; meanwhile, the texture modeling can be diversified, so that the texture modeling of the coating is rich and diverse.

4) Compared with the texture coating made of wallpaper and wall cloth in a layered mode, the sandwich structure has obviously better anti-stripping capability, and compared with the coating made of glass fiber cloth in the prior art, the sandwich structure is obviously smaller in coating weight and has no loss of pit cracking capability.

5) The method of the invention can produce texture on the surface of the object, no obvious gap can be generated at the butt joint, and the texture consistency is good;

6) the method can produce abundant textures similar to wallpaper on the surface of an object.
