Description

A manufacturing method of embossing wall paper using natural materials

The present invention relates to a method for producing an embossed wallpaper which has a soundproofing, moisture proof, and antibacterial effect by using wood powder, diatomaceous earth, rosin, plastic shell powder, etc., which are natural materials, and more specifically, particles generated when processing wood at a mill or the like. By mixing the waste wood powder with the adhesive on the base material of non-woven fabric or imitation paper, the wallpaper is made the same / similar to the general wallpaper products, but the embossed surface is more uniform than the existing products, and the sound insulation and insulation required by the wall are required. The present invention relates to a method for producing a wallpaper containing wood flour and functional ingredients which can have a parallel effect.

As is generally known, wallpaper is applied as a base material of paper, vinyl, and fiber attached to the wall for decoration, and this wallpaper suggests various types of wallpaper to impart various functions by escaping the basic function already attached to the wall. It is used.

In other words, the surface is simply coated with a vinyl-based sheet to keep warm, soundproof and water-washing required by the wall to be adhered to by removing the basic concept of simply attaching wallpaper having various patterns on the base material to the room. A product is appearing.

Sick House Syndrome is a term that causes residents to feel uneasiness and health problems due to toxic substances from building materials and wall paper used for building new buildings. Sick house syndrome is a substance causing sick house syndrome. Benzene, chloroform, There are volatile organic compounds called VOCs (Volatile Organic Compounds) such as styrene and formaldehyde, which contain carcinogens.

In addition, there may be contaminants such as radon, asbestos, carbon monoxide, carbon dioxide, nitrogen oxides, ozone, fine dust, and airborne bacteria that occur when building a house, and other organisms such as bacteria, mites, etc. Pollution is a factor, but when these pollutants are not discharged out of the building and accumulate indoors, they cause various problems.

Recently, as the awareness of the residential environment pursues well-being, research on the management of indoor air quality and harmful pollutants is being actively conducted. In addition to removing the VOCs through fabrication or wallpaper, a method for creating a comfortable indoor environment and securing deodorization and antibacterial activity is required.

In the conventional wallpaper technology, the wallpaper using wood powder is proposed to obtain sound insulation and thermal insulation effect. The basic manufacturing process is a base material supply step of supplying a nonwoven fabric, imitation paper, vinyl or fiber as a base paper, and an adhesive on the upper surface of the base material. It consists of a step of applying an adhesive and the coating of wood powder to form a wood powder layer and embossing after pressing, winding and packaging after cooling.

The wallpaper provided through the manufacturing process was embossed to give a three-dimensional effect, but in the process of scattering wood flour, which is one of the manufacturing processes, a problem was caused in uniform scattering and adhesion, and the applied wood powder layer was not uniform. As a result, many troubles occur during the printing and surface treatment steps.

Specifically, the conventional scattering method is a guide roll between the lower vessel and the upper guide roll in the process of applying the adhesive to the non-woven fabric, imitation paper or vinyl or fiber paper layer as a base material, the excess vessel powder in the lower vessel is transferred to the upper guide roll The vibrator of the type is vibrated to shake off only a certain amount of scattering. In the course of this process, the relatively large particle size of the wood flour tends to be concentrated on both sides of the width of the finished product. In the analysis, relatively fine particle size of wood powder is coated in the middle, and relatively thick particle size of wood powder is coated, resulting in a relatively uneven amount of coating in the adhesion, printing, and surface treatment processes. When it comes to the finished wallpaper, the problem of shade of color and uneven coating Effect is reduced and, therefore, has a problem in that mistaken for a lower quality.

In addition, in order to save costs in the wallpaper manufacturing process, the waste wood powder generated in the processing of wood at the sawmill is pulverized and used. Since the moisture content is different depending on the source of the raw wood powder used, the wood powder is also used in the wallpaper manufacturing process. It affects the wallpaper quality according to the water content of and the wood powder absorbs the moisture in the air excessively even after being constructed as a wallpaper, and the wallpaper is easily damaged. Has

In addition, in recent years when the well-being culture of consumers has been expanded and air quality is important, wallpaper that has added ingredients that can contaminate indoor air or have the potential to release VOCs and rather benefit the human body As a product, a product different from the existing wood powder wallpaper is needed.

The present invention has been made in order to solve the fundamental problem that the above-described wallpaper is retained, but the wallpaper is produced by using wood powder generated in the process of processing wood at the sawmill, etc. Manufacture of wallpaper that adds functionality by using environmentally friendly adhesive raw materials that do not contain harmful ingredients and functional ingredients having affinity with wood flour while using wood flour that has undergone a pretreatment process to remove the absorbency of wood flour used as a main raw material.
