Embodiment 1

[0120] refer to Figure 1A , the present invention impregnates and coats composite anti-crack texture sandwich coating, or coating structure is as follows:

[0121] The surface of the wall body 10 is impregnated with a composite anti-crack texture sandwich coating, or the coating includes a first coating 20, a second coating 40, and fibers sandwiched between the first coating 20 and the second coating 40 Texture Network Sandwich 30.

[0122]Wherein, the fiber texture network sandwich core 30 contains a three-dimensional interpenetrating network structure formed by fibers, and the fibers include horizontal fibers, vertical fibers and fibers in an oblique direction, Figure 2A-Figure 2C The top view structure of several fiber texture network sandwich cores 30 is given, refer to Figure 2A-Figure 2C , in the same plane, the transverse fibers 5 intersect with the longitudinal fibers 4 and oblique fibers 3, and the intersecting fibers enclose the mesh 2. The intersections between...

Embodiment 2

[0141] In the present embodiment, the method of making the dip coating compound anti-crack texture sandwich coating or coating is as follows:

[0142] Coating an organic adhesive on the surface of the wall body 10, such as an epoxy resin adhesive, or coating the organic adhesive on the surface of the fiber texture network sandwich core 30, as the first coating, the fiber texture network sandwich core 30 passes through The organic adhesive is pasted on the surface of the body of wall 10,

[0143] By applying pressure, the organic adhesive soaks into the fiber and penetrates into the pores of the three-dimensional interpenetrating network structure;

[0144] Coating an organic coating to form a second coating, applying pressure to make the organic coating infiltrate the fibers of the three-dimensional interpenetrating network structure and immerse into the meshes of the three-dimensional interpenetrating network structure; forming a sandwich coating;

[0145] When the sandwich ...

Embodiment 3

[0150] In the present embodiment, the method of making the dip coating compound anti-crack texture sandwich coating or coating is as follows:

[0151] Coating the first organic paint on the surface of the body of wall 10, such as latex paint, forms the first coating 20;

[0152] Applying the fiber texture network sandwich core 30 to the surface of the first coating 20, applying pressure to the fiber texture network sandwich core 30 to make the first organic coating soak into the fiber and penetrate into the pores of the three-dimensional interpenetrating network structure;

[0153] Coating the second organic coating, also can be latex paint, as the second coating, apply pressure to make the second organic coating infiltrate the fibers of the three-dimensional interpenetrating network structure, and immerse in the mesh of the three-dimensional interpenetrating network structure; form a sandwich Coating; when the sandwich coating is cured, the organic coating on the surface of t...

Abstract

The invention provides a kind of impregnation coating compound anti-cracking texture sandwich coating, coating and the method for making the coating or coating on the surface of an object, before the first coating loses plasticity, the fiber texture network sandwich paste Covered in the first coating, the fiber texture network sandwich contains a three-dimensional interpenetrating network structure formed by fibers, and the coating of the first coating infiltrates the fibers and penetrates into the meshes of the three-dimensional interpenetrating network structure; then coating The second coating, applying pressure to make the coating of the second coating soak into the fibers of the three-dimensional interpenetrating network structure and immerse in the meshes of the three-dimensional interpenetrating network structure; curing the sandwich coating, the second coating is during the curing process The paint on the mesh surface of the three-dimensional interpenetrating network structure collapses inward, while the coating on the fiber surface is blocked by the fibers and does not sink or forms a small sink, thus forming a texture. The invention can produce textures in a standardized and large-scale manner, and has good crack resistance.

Description

technical field [0001] The invention relates to a method for decorating the surface of an object, in particular to a method for making an anti-cracking texture sandwich coating and paint on the surface of buildings and the like. Background technique [0002] Wall paint refers to the decoration and protection of the building wall, making the building wall beautiful and tidy, and at the same time protecting the building wall and prolonging its service life. In the specific technical field, the development of various binder film-forming technologies has greatly improved the performance of coatings, especially the development of emulsion preparation technology is particularly important. Existing coatings form a system consisting of binders, fillers, pigments, additives and solvents (such as water). In order to reflect the environmental protection performance of coatings, inorganic binders (such as silicates) and various water-based emulsions are commonly used as the bonding and...
