## Abstract

The present invention discloses an assembly of prefabricated wall modular decoration, comprising a conventional decorative material, a plate, a movable laminating layer and a protective layer. The conventional decorative material being mounted on the surface of the plate, a number of movable laminating layers being evenly spaced between the plate and the protective layer making a sound-insulated air gap between them, and the protective layer being mounted on the surface of the wall. The present invention also discloses an installation method for the assembly above. Due to the traditional decorative material, the plate, the active lamination layer, and the protective layer of the present invention are set to be installed on the wall in turn, together with the sound-insulated air gap within the structure, which is not only simple to manufacture and easy to install, but also has better sound absorption performance which could reduce the noise nuisance.

## Claims

### Claim 1

A production and installation method for assembly of a prefabricated wall modular decoration, comprising:
S1. editing, typesetting and making construction plans in accordance with dimensions of a wall to make a modular splicing plan for a prefabricated wall decorative assembly;
S2. cutting plates into specified sizes in accordance with the modular splicing plan and marking each plate with a label, sequentially, to assist with assembly and installation of a finished product in accordance with the modular splicing plan;
S3. adding and mixing additives with silver ions or copper ions, having_antibacterial function, to the liquefied state of raw materials in a conventional decorative materials manufacturing process, so that the surface of the conventional decorative materials has an antibacterial function after forming;
S4. applying or laying the conventional decorative materials, which have silver or copper ions attached, on the plates;
S5. laminating a first double-sided sticker onto a first latex layer, then laminating a second double-sided sticker between the first latex layer and a first plasticized stem locking layer, laminating a fourth double-sided sticker onto a second latex layer, then laminating a third double-sided sticker between the second latex layer and a second plasticized stem locking layer, and finally, the first plasticized stem locking layer and the second plasticized stem locking layer are combined together to form a movable laminating layer, which is cut into a certain size and inlaid or laminated to the bottom of the plate at uniform intervals;
S6. coating the wall surface with at least two protective layers to increase bonding capability of the wall surface; and
S7. laminating the finished product to the protective layer in accordance with the modular splicing plan, wherein a sound-insulated air gap of 5-6 mm is formed between the plate and the protective layer.
