Assembly of prefabricated wall modular decoration and its production and installation method

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.
