Problems solved by technology

[0003] However, there are few applications of PVC wallboards on the market. Based on the existing floor calendering production process, there are still some problems in the process development of wallboards: (1) Wallboards are perpendicular to the wall and different from the ground, so It is necessary to improve the adhesion performance of the wallboard adhesive; (2) the wallboard is attached to the wall and is easily polluted by graffiti, so it is also important to provide its resistance to graffiti pollution; (3) to improve the flame retardancy of the wallboard, Reducing the smoke index is also conducive to preventing the spread of fire

Abstract

The invention discloses a preparation method of a DIY PVC wallboard. Flame retardant substances are added into a prepared bottom sheet of PVC wall cloth, so that the fire resistance of the wallboard is excellent and the safety performance is improved; the surface is treated by adopting a special UV process, the surface has high stain resistance and is very convenient to clean, only a rag is neededto wipe off stains, which saves trouble for consumers; the prepared DIY PVC wallboard has processability and is easy to cut, so that the wallboard can be DIY according to the needs of the consumers;the surface does not need to be painted again; in addition, compared with logs, the wallboard has more physical advantages and good stability, in daily use, the wallboard is not prone to cracking, edge warping and cross grain, the wallboard is corrosion resistant and easy to maintain, the wallboard is very convenient to install; and compared with plastic wallpaper and wall cloth, the PVC wallboardhas higher hardness and longer service life.

Description

technical field [0001] The invention relates to the field of preparation of a wallboard, in particular to a preparation method of a DIY PVC wallboard. Background technique [0002] At present, PVC flooring on the market has broad application prospects due to its excellent wear resistance, decorative properties, stain resistance and chemical reagent resistance. [0003] However, there are few applications of PVC wallboards on the market. Based on the existing floor calendering production process, there are still some problems in the development of wallboards: (1) Wallboards are perpendicular to the wall and different from the ground, so It is necessary to improve the adhesion performance of the wallboard adhesive; (2) the wallboard is attached to the wall and is easily polluted by graffiti, so it is also important to provide its resistance to graffiti pollution; (3) to improve the flame retardant performance of the wallboard, Lowering the smoke index also helps prevent the s...
