Description

Technical Field

[0001] This invention relates to the field of seamless wallcovering technology, specifically to a functional and environmentally friendly seamless wallcovering. Background Technology

[0002] Seamless wall coverings, also known as seamless wallpaper, are a type of wall covering product developed in China in recent years. They are designed according to the height of interior walls and can be applied as a single piece along the perimeter of the wall. Seamless wall coverings can be custom-cut to fit the room's perimeter, with a width greater than or equal to the room's height. One sheet of fabric is used per room, eliminating the need for splicing. Features include seamless application, a strong three-dimensional effect, fire resistance, and washability.

[0003] Currently, although existing seamless wall coverings have added anti-fouling finishing processes in their pre-processing, their overall anti-static capabilities are still poor. This causes the wall coverings to attract dust and become contaminated in dry weather, which has a certain impact on people's lives. At the same time, the adhesive layer in existing seamless wall coverings releases volatile gases, affecting people's health. Therefore, it is necessary to develop a functional and environmentally friendly seamless wall covering to solve this problem and meet market demand. Summary of the Invention

[0013] S5. After the treated surface fabric, middle layer and bottom fabric are stacked in sequence, they are fed into the hot press roller through the guide belt in the laminating machine, so that the surface fabric, middle layer and bottom fabric are directly laminated into one.

[0014] S6. The composite fabric from step S5 is fed into a cooling roller via a guide belt for cooling, thus obtaining a functional, environmentally friendly, seamless wall covering.

[0015] Preferably, the pigment filler is a mixture of titanium dioxide and barium sulfate, and the mixing ratio of titanium dioxide to barium sulfate is 6:4.

[0016] Preferably, the film-forming aid is a mixture of titanium dioxide and calcium carbonate, and the mixing ratio of titanium dioxide to calcium carbonate is 3:7.

[0023] (III) Beneficial Effects

[0024] This invention provides a functional, environmentally friendly, seamless wall covering. It has the following beneficial effects:

[0025] (1) This functional and environmentally friendly seamless wall covering has good anti-static ability by injecting stainless steel fibers into the surface layer. In dry weather, the surface of the wall covering is less likely to be contaminated by dust, thus ensuring the quality of life and reducing the number of times people need to maintain the wall covering. At the same time, the use of the middle layer gives the seamless wall covering a good ability to prevent mold growth.

[0026] (2) This functional environmentally friendly seamless wall covering can avoid the use of adhesives by using activated carbon nonwoven fabric and the use of the middle layer. The middle layer uses water-based raw materials, which will not produce harmful volatile organic compounds, which is beneficial to people's health. At the same time, the activated carbon nonwoven fabric can absorb harmful gases during the production process, which meets market demand.

[0027] (3) This functional and environmentally friendly seamless wall covering, by adding titanium dioxide and barium sulfate as pigment fillers, not only has the advantages of good wettability and good chemical stability, but also can prevent the penetration of ultraviolet rays and moisture, thus extending the service life of the seamless wall covering.
