Description

Wallpaper {Wall Paper}

The present invention relates to a wallpaper, and more particularly, to a wallpaper to improve workability when the paper is formed by forming an adhesive layer having an antibacterial function on one surface of the wallpaper.

In general, the wallpaper is a variety of the fabric is provided with a paper or a tissue paper, etc., one surface of the wallpaper provided in this way was applied by applying a paste or glue on the wall surface of the target object.

However, such a conventional wallpaper has been very cumbersome because the work of applying grass to one surface of the wallpaper cut to a size corresponding to the wall surface, which is the target object, must be performed inevitably.

In addition, in order to solve the above problems, a sticker adhesive is formed on one surface of the wallpaper and protected as a release paper, and then the release paper is peeled off during use of the wallpaper, and then the adhesive is applied to the wall surface. The adhesive force gradually decreases and eventually the wallpaper falls from the wall, and the dropped wallpaper has a problem in that it cannot be reattached due to the adhesive having a reduced adhesive strength.

In particular, when trying to remove the wrong wallpaper from the wall and reattach it, the sticker adhesive is already contaminated by the foreign matter and the adhesive force is significantly reduced, so that it cannot be reattached to the wall.

As described above, the conventional wallpaper attached to the wall has a problem in that when water or moisture is generated on the wall due to a temperature difference with the outside, mold or bacteria are generated and propagated to stain the wallpaper and become contaminated.

Accordingly, the present invention has been made to solve the conventional problems as described above, by forming an adhesive layer having an antimicrobial function on one side of the fabric of the wallpaper to solve the trouble of applying the adhesive during the paper work is improved workability The purpose of this invention is to provide a wallpaper that can be detached and attached to the wall repeatedly and to prevent contamination of the wallpaper and to keep the indoor environment clean.

Also, the deodorant illite is also pulverized into 1000 mesh and added.

The liquid antimicrobial base coating composition thus formed is poured onto one of the surface fabrics selected from cotton jacquard, poly jacquard, poly pillow jacquard, chanel polysatin, silk, artificial dog, and acetate, and then coated with a knife method to give an antibacterial base. The thickness of the coating layer is formed to 0.2 to 0.5 mm.

Subsequently, the antimicrobial base coating agent layer coated as described above is first dried with hot air at 150 ° C., completely dried as a heater and hot air at 150 ° C., and then an antibacterial hot melt adhesive layer is formed on one surface thereof.

Formation of antibacterial hot melt adhesive layer

With respect to the composition constituting the antibacterial hot melt adhesive layer, that is, the base polymer 35wt%, tackifier 20wt%, wax 20wt%, plasticizer 12wt%, antioxidant 5wt%, filler 5wt%, elastomer 3wt% 100wt%, An antimicrobial agent, an anion agent, and a deodorant are added at a ratio of 4: 3: 3, and heated and mixed at a temperature of 130 to 180 ° C. to form a liquid antibacterial hot melt adhesive composition.

At this time, the antimicrobial agent, anionic agent, deodorant is made of the same composition as in the step of forming the antimicrobial base coating agent layer described above, and is pulverized into 1000 mesh is added.

Applying the antimicrobial hot melt adhesive composition of the liquid state melted at 150 ~ 170 ℃ formed as described above on one side of the fabric or one side of the antimicrobial base coating agent layer by pressing with a roller to evenly form the thickness of the antibacterial hot melt adhesive layer to 0.2 ~ 0.4㎜. .

Thereafter, by pressing the applied antibacterial hot melt adhesive layer again as a roller maintaining a temperature of 160 ~ 170 ℃ to remove all the bubbles formed in the antibacterial hot melt adhesive layer, and completely dried by infrared heater and hot air to prevent the antibacterial hot melt adhesive The layer is cured.

For reference, the manufacture of the wallpaper as described above, already registered by the present inventors Patent No. 10-0352144 (registration date: 2002.08.27, application number: 10-2000-12809, application date: 2000.03.14) It is made through the manufacturing apparatus disclosed in.

On the other hand, when the wallpaper formed as described above is used, the antibacterial hot melt adhesive may be melted with a thermal dryer of 120 to 150 ° C. heated to 80 to 120 ° C. or more, and then the wallpaper may be attached to the wall surface of the object.

At this time, if the fabric of the wallpaper is thin, the use of thermal iron is advantageous, and the use of a heat dryer is advantageous in the case of using a thick fabric such as jacquard.

Therefore, as shown in the related art, the hassle of painting grass or bond on one surface of the wallpaper is eliminated, and the papering work is easily performed, and it is possible to maintain a clean indoor environment by suppressing mold or bacteria.

As described above, the wallpaper of the present invention, by forming an antibacterial hot melt adhesive layer having an antimicrobial function on one side of the fabric of the wallpaper, to eliminate the hassle of applying the adhesive during the paper work to improve workability, wall wallpaper It can be repeatedly attached to and detached from the mold, preventing the contamination of the wallpaper by inhibiting the mold, bacteria, etc., and has the effect of maintaining a clean indoor environment.
