Electromagnetic shielding impregnation coating sandwich wall cloth and manufacturing method thereof

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...

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 firmness of the bond is often relatively poor. Especially environmentally friendly adhesives such as glutinous rice glue are easy to absorb water and become moldy, causing the wall covering to fall off; Under normal circumstances, the seams between the wall coverings are very obvious, which seriously affects the decorative effect and the design of the color and pattern of the wall covering. 4) The 3D effect is poor. The principle is to produce a 3D effect, which is often thicker and has a greater limitation on the viewing angle.
