[0028] (1) The present invention breaks the traditional inertial thinking of the wallpaper and wall cloth industry and provides a new technical idea and solution. While achieving the same or highly similar surface decoration effect, it can also solve the many drawbacks, pain points and shortcomings of wallpaper and wall cloth that have been reported and exposed in the actual application and promotion process at a relatively low cost (for example: Class A non-combustible performance and fireproof performance, waterproof and moisture-proof, antibacterial and mildew-proof performance, surface stain resistance, surface aging resistance, color retention, as well as odorless, odorless and healthy and environmentally friendly performance and other key performance and quality indicators. The problem of poor performance, etc.) can be completely solved when wallpaper and wall cloth finishing effects are applied to wall decoration in the field of indoor commercial space decoration. The problem of high risk of after-sales customer complaints and high probability of claims is faced, so that the product has better wallpaper and wall cloth surface decoration effect and surface performance, helping the industry to develop new quality productivity, and can be used as an excellent substitute for wallpaper and wall cloth and a solution for upgrading and improving quality and efficiency.

[0029] (2) The present invention, as a new type of wall decoration material mainly used in the field of indoor commercial space decoration, has very outstanding differentiation characteristics compared with traditional wallpaper and wall cloth. It looks like paper but not paper, like cloth but not cloth, and has very obvious appearance and performance characteristics. It not only inherits and upgrades the grade, appearance and finishing effect (color, texture, grain, texture, touch, feel and its comprehensive decorative effect) of wallpaper and wall cloth, but also has the ultimate product performance of fireproof A grade non-flammable, waterproof and moisture-proof, 0 grade mildew-proof, 1 grade antibacterial and antiviral, 5 grade stain resistance, 6 grade light fastness, the highest grade of aging resistance and anti-discoloration, 1 grade odorless and odorless, formaldehyde-free and non-toxic grade health and environmental protection.

[0030] (3) In addition, it has excellent performance in fire resistance and non-combustibility: it can achieve the best non-combustibility level: Class A non-combustibility; during the combustion test, almost no smoke is generated, and the smoke production characteristic level can reach the best level: Class 1; the level of burning drips or particles can reach the best level: Class D0, no burning drips; the smoke toxicity level can reach the best quasi-safety level ZA1, almost no toxicity. However, the combustion performance and fire resistance level of conventional wallpaper and wall cloth can only achieve Class B1 difficulty in combustion, and the amount of smoke produced during combustion or fire is large, there is burning dripping, and there is a certain degree of slight smoke toxicity; therefore, conventional wallpaper and wall cloth cannot be used in public buildings and high-rise buildings, etc., where the fire resistance level of indoor wall decoration materials is required to be non-combustible (Class A). The invention of the utility model is a boon for interior decoration and space designers, and is a major improvement and breakthrough in traditional wallpaper and wall cloth, so that the decorative effect of wallpaper and wall cloth can be implemented in projects and application scenarios where the fire resistance performance requirement is Class A non-combustibility.
