Abstract

PURPOSE: Wallpaper obtained by coating a specified amount of an adhesive on ordinary wallpaper and then coating wood powder, rice hull powder and the like thereon and an apparatus thereof are provided. This method has an effect on saving resources and reducing environmental pollution as well as providing wallpaper having excellent smoothness. CONSTITUTION: An adhesive is coated on the surface of ordinary paper(1) such as wood-free paper and reclaimed paper in an amount of 20 to 100g/m¬2 on a solid basis by passing through a gravure mesh roller. The adhesive coated paper is coated with wood paper(pine tree, juniper, pine nuts, fir tree or the like), rice hull powder, mugwort powder by passing through a gravure roller(3, 4) and a pressure roller(5) and subjected to passing through a roller(7) to remove the excessively attached materials. Thereafter, the pretreated wallpaper is subjected to passing through a first drying oven(8) and a compression roll(9) to give smoothness to the wallpaper and top coating treatment to prevent detachment and staining of the half product.

Description

Wallpaper and machinery using wood flour, chaff powder, wormwood powder, etc. {.}

The present invention is a new type of wood powder (wood powder such as pine, juniper, fir, white pine, meat, etc.), chaff powder, wormwood powder, hay powder, dried water powder than the method for bonding wood powder to the nonwoven fabric described in Patent Registration No. 0166630. The present invention intends to form a wallpaper having a mechanism and a product structure capable of attaching a raw material such as a wallpaper to the wallpaper.

The existing method of attaching wood powder to a nonwoven fabric (Patent No. 0166630) uses a method of generating static electricity by using high voltage (a kind of flocking method) and uses a nonwoven fabric as a base for wood powder attachment.

In this case, the nonwoven fabric is not regenerated (in the case of recycled nonwoven fabric, the raw material price is very expensive), and the dryness of the adhesive binder and excessive use of the adhesive binder can also be a problem when penetrating the adhesive binder deep inside the nonwoven fabric. Because of the elongation (elasticity) of the front, back, left and right, it should be equipped with a dent.

The present invention uses a common wallpaper paper (white paper and recycled paper produced in a general paper mill) to solve this problem, and the surface coating layer formation and the composition of the mechanical device to prevent the desorption and contamination of raw materials of the product is configured in a gravure method The wood flour, chaff flour, wormwood powder, hay flour, dried grass flour, etc. to more efficiently attach the material.

A certain amount of adhesive is applied to the wallpaper paper (white paper and recycled paper) commonly used in a gravure method (20-100 g / m2 on a fixed basis), and the paper passed through the gravure mesh roll is about 20 to 45 degrees with the gravure mesh roll. At an angle (upward direction), the paper is passed between the gravure-shaped roll and the roll formed horizontally at a distance of 30 cm to 100 cm in the direction of the wallpaper paper running direction (with a certain amount of adhesive applied). Wood flour separated by granularity (pine, juniper, fir, pine, meat, white pine, etc.) The outer roll of two gravure rolls formed horizontally by supplying raw materials such as chaff, mugwort, hay, and dried grass Rotation in the reverse direction of travel (another gravure roll acts as a guide roll with the original paper wrapped). By is attached to the sheet.

The raw material attached to the base paper is to dry the adhesive while passing through the drying oven and press the roll again to adjust the smoothness of the product, and again to treat the surface top coating to prevent the raw material desorption and contamination of the product to compose the product.

An embodiment of the present invention will be described with reference to the accompanying drawings.

1) Adhesive application step

An adhesive is applied while the wallpaper paper 1 wound around the paper tube having a constant width and length passes through the gravure mesh roller in a taut state by several guide rolls. (The gravure roller uses two-stage and three-stage rolls, and the amount of adhesive applied is applied between 20 ~ 80g / ㎡ based on solid content.The adhesives used are PE, EVA, EVA containing biodegradable surfactant, acrylic adhesive , Adhesives such as fluorine and polyazole are used.)

2) Gravure rolls (3.4) formed horizontally with adhesive applied to the base paper, such as wood flour, rice husk, wormwood, hay flour, dry grass, etc. If you supply raw materials such as wood flour (pine, juniper, pine, fir, white pine, meat, etc.), rice hull, wormwood, hay, dry grass, etc., roll (4) is rotated in the reverse direction of the paper, It is pressurized so that it can be easily attached to the paper on which the adhesive is applied. (Roll (4) is installed to be able to move forward and backward. Keep the gap with roll (3) properly.)

Roll (5) is also rotated in the reverse direction of the paper's advancing direction so that the raw material can be easily attached to the paper. (At this time, the surface shape of the roll (4) is engraved with an inclined oblique line in a diamond shape for easy pressurization, and the surface shape of the roll (5) is engraved with an inclined and embossed oblique line in the longitudinal direction for easy pressurization. At this time, wood flour and other raw materials can be supplied manually (of FIG. 1), or an automatic feeding device (12. 13) can be used as shown in FIG.

3) The process of attaching the raw material to the base paper constantly and the step of removing excessively attached raw material

Since the raw materials attached to the paper are excessively attached as needed, the raw materials are piled up due to the movement speed of the paper. , 8 angles, 12 angles, 16 angles) can be rotated in the reverse direction of the paper advance direction to shake off the excessively attached raw material and to make the raw material adhere to the paper uniformly.

4) Smoothness work stage

After passing the raw material attached to the base paper through the primary drying oven (adhesive drying) (8) press the compression roll (9) to adjust the smoothness of the product.

(The job is to adjust the thickness of the left and right center of the product.)

5) Top coating layer coating step

Top coating can be performed like a multi-degree printing process by several times, such as 1 degree, 2 degree, 3 degree, 4 degree, etc. to prevent desorption, color treatment, and contamination of surface raw materials of dry pressurized products. (In this way, various printing patterns work on the surface of the product and the top coating layer can be carried out simultaneously.)

When the work is carried out as described above can be used as an adhesive binder alone, it may be used by adding a conventional antimicrobial agent and far-infrared radiation materials such as ocher, illite, elvan, jade, germanium, ceramic, charcoal powder.

Example 1) Mixing Ratio Weight% of Adhesive Binder and Radiating Material

The resin used for the top coating layer (4 in FIG. 3) may be used alone or in combination of two or more kinds of resins such as PE, EVA, acrylic, surfactant-containing EVA, fluorine, and urethane waxes. In order to achieve this, it is possible to add functionality such as far-infrared radiation materials such as fertilizer, TIO ₂ , loess, illite, elvan, jade, germanium, ceramic, and charcoal powder.

At this time, the coating amount of the top coating agent is applied to 50 ~ 200g / ㎡ based on the solid content.

Example 2 Mixing Ratio Weight% of Top Coating Resin

Example 3) Mixing Ratio Weight% of Top Coating Agent Resin and Far Infrared Radiation Material

The present invention as described above is intended to suppress the effect of recycling the resources and environmental pollution at the time of producing wallpaper using natural materials such as wood flour, rice husk flour, wormwood powder, hay flour, dried water grass flour.
