Problems solved by technology

[0004] However, the wall cloth also has the following problems: 1) The environmental protection performance is poor, and the wall cloth needs to be pasted to the wall surface. Most of the adhesives currently used are still organic solvent-based adhesives, which contain a large amount of toluene, formaldehyde, etc., which are harmful to the human body. 2) It is not tear-resistant, and adhesives are used to adhere between the wall covering and the wall. The adhesion between the adhesive and the wall is uncontrollable, and the fir

Embodiment 1

[0154] refer to Figure 1A , the structure of the electromagnetic shielding impregnation coating sandwich wall covering of the present invention is as follows: the impregnation coating composite sandwich coating complex comprising the base color coating 11, the base color coating surface, and the impregnation coating composite sandwich coating complex It includes a transparent or translucent first coating 20 , a transparent or translucent second coating 40 , and a fiber network sandwich core 30 sandwiched between the first coating 20 and the second coating 40 . Wherein, conductive fillers are added in the base color coating 11, so as to provide the coating with an electromagnetic shielding function.

[0155] In this embodiment, 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 ...

Embodiment 2

[0176] In the present embodiment, the method for making electromagnetic shielding impregnation coating sandwich wall covering is as follows: coat the base color coating 11 on the surface of the wall body 10,

[0177] After the base color coating 11 is dried, a transparent organic adhesive, such as an epoxy resin adhesive, is applied on a part of the surface of the base color coating 11, and the fiber texture network sandwich core 30 is pasted to the bottom by the organic adhesive. Color coating 11 surface;

[0178] 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;

[0179] When the sandwich coating is cured, the organic coating on the surface of the mesh sags inwardly, while the organic coating on the surface of the fiber is blocked ...

Embodiment 3

[0185] In the present embodiment, the method for making electromagnetic shielding impregnated and coated sandwich wall covering is as follows:

[0186] The surface of the wall body 10 is coated with a primer coating 11,

[0187] After the base coat 11 is dried, the base coat 11 surface is coated with a transparent or translucent first organic coating, such as latex paint, to form a transparent or translucent first coating 20;

[0188] 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;

[0189] Apply transparent or translucent second organic paint, also can be latex paint, as a transparent or translucent second coating, apply pressure to make the second organic paint infiltrate the fibers of the three-dimensional interpenetrating net...

Abstract

The invention provides an electromagnetic shielding impregnation coating sandwich wall cloth and a method of manufacturing the electromagnetic shielding impregnation coating sandwich wall cloth or anobject decoration method. The electromagnetic shielding impregnation coating sandwich wall cloth comprises a bottom coating and an impregnation coating composite sandwich coating composite body applied to the surface of the bottom coating; and the impregnation coating composite sandwich coating composite body comprises a transparent or semitransparent second coating and a fiber texture network sandwich wrapped in the second coating, the fiber texture network sandwich comprises a network structure formed through fibers, the second coating permeates into net holes of the network structure, and one or more of the bottom coating, the second coating and the fiber texture network sandwich have an electromagnetic shielding function. According to the electromagnetic shielding impregnation coatingsandwich wall cloth and the method, the wall cloth with textures and/or patterns can be manufactured in a standardized and large-scale manner, and the wall cloth has the good anti-cracking performance, air permeability and decorative performance.

Description

technical field [0001] The present invention relates to a decoration on the surface of an object, a preparation method thereof, and a method for decorating the surface of an object, in particular to a method for making an impregnated and coated sandwich wall cloth with electromagnetic shielding function on the surface of a building and other objects, and a Impregnation coated sandwich wall covering for shielding function. Background technique [0002] Early wall decoration is to use wall paint, wall paint refers to the decoration and protection of the building wall, so that the building wall is beautiful and tidy, and it can also protect the building wall and prolong 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...
