Description

Manufacture method of aqueous foamed wallpaper having high-resolution printing effect

The present invention relates to a method for producing an aqueous sol foam wallpaper having a high resolution printing effect, and more particularly, by improving and improving the surface smoothness of a foam wallpaper that excludes harmful substances to the human body, thereby improving the printing effect, It is possible to print a variety of designs through, and to a method for producing an aqueous sol foam wallpaper having a high-resolution printing effect that can enhance the printing effect.

In general, wallpaper is generally applied to the wall to maximize the interior effect of the interior space to protect the wall surface and enhance the decoration.

Such a wallpaper is hung and then placed on it, printed with various patterns on the sun, printed on cloth, and woven in order to be applied to the wall from the beginning. (Vinyl chloride sheet).

In other words, depending on the material to be produced, paper laminated wallpaper, silk wallpaper, textile (fabric) wallpaper is used.

The laminated paper wallpaper overlaps two sheets of paper wallpaper, which is generally used in a room where people mainly reside, but it is difficult to obtain a high interior effect.

The fabric (fabric) wallpaper is formed of cloth has the advantage of increasing the interior effect, but the cost was expensive and the appearance was easily damaged.

The silk wallpaper is commonly used in common areas such as living rooms or kitchens, and the material is generally manufactured using PVC (vinyl). In particular, the silk wallpaper can be wallpapered without applying a cover paper, and the wallpaper is torn off when the wallpaper is replaced. It is also used most often because it is easy to peel off the dirt with a mop.

Of the above-mentioned wallpaper, silk wallpaper is widely used for many advantages such as excellent design and formability, but by using chemicals such as PVC, it can harm the health due to symptoms such as sick house syndrome, and it is expensive compared to paper and harmful by PVC component. Atopic substances can be induced as a substance, and in case of fire, toxic gases are generated to increase the damage. In addition, there was a problem that the wallpaper is sagging or crying on a wet day.

In order to solve such a problem, an aqueous sol (system having colloidal particles dispersed in a liquid and having fluidity) having a moldability comparable to a silk wall but having a PVC composition is provided.

As such, the aqueous sol wall paper, as shown in Figure 1, the paper input step (10) of the paper or non-woven fabric, the aqueous foam sol (3) (colloid particles are dispersed in the liquid on top of the paper 2) Designed on top of the sol coating step (20) to coat the fluidity), the foaming step (30) to apply the heat to the sol-coated base paper (2) by applying heat to the oven foaming, the foamed aqueous sol layer (3) It is generally manufactured by a printing step 40 for printing the embossing step 50 to increase the formability by applying heat to the printing surface.

However, in the above-described general method of manufacturing an aqueous sol wallpaper, the surface of the aqueous sol layer 3 is foamed as the foaming step 30 is foamed as shown in FIG. There was a problem that was difficult to print the design on the surface.

In addition, in order to solve the above-described printing problem, as shown in Figure 3a, after the paper feeding step 10, the sol coating step 20, the foaming step 30, the surface ironing step (30-1) After the printing step 40 or as shown in Figure 3b, after the surface ironing (30-1), a transparent treatment agent coating step (30-) to coat the transparent treatment agent to ensure the smoothness of the aqueous sol layer (3) A method of performing 2) is provided.

However, if the surface is cured after being foamed in an oven, it is also characterized by an aqueous foaming foam which does not have a gel phenomenon even when heat is applied. There was a slight problem.

In addition, in the embossing step, due to the problem of having to apply a high pressure of about 10 ~ 60kg / cm2 for molding there was a problem that the embossing is broken due to poor fluidity after the embossing operation.

An object of the present invention is to solve the above-mentioned problems of the prior art, to provide a method for producing an aqueous scrubbing wallpaper having a high-resolution printing effect by ensuring the smoothness of the printing surface without containing a harmful substance to the human body.

In addition, by printing various patterns on the surface of the water-based foamed wallpaper wallpaper, it is possible to print out the computer-generated or existing stored designs or images and to print precise and high-quality patterns and images on the surface of the foam wallpaper. It is to provide a method for producing an aqueous brushed foam wallpaper having a high-resolution printing effect that can be printed.
