Description

Interior materials using silver grass and manufacturing method

The present invention relates to indoor interior materials using silver grass pulp, and more particularly, to mix indoor grass pulp obtained from silver grass with natural pulp, such as doc pulp, wood pulp, paper pulp, etc. By manufacturing in the form of excellent breathability, antibacterial and deodorant as well as harmless to the human body relates to the interior interior materials with an environmentally friendly and visual aesthetics.

In general, various finishing materials, such as brick, marble, board, veneer, and panel, or flooring, wallpaper, and ceiling, are used for finishing or decorating a structure of a building. Due to the harmful substances coming out to damage the various syndromes are increasing interest in environmentally friendly interior interior materials harmless to the human body. For example, the wallpaper using natural plants or natural minerals to reduce the emission of harmful substances and at the same time a number of wallpaper that emphasizes the aesthetic aspect is coming out, the Republic of Korea Patent Publication No. 10-0554875 No. Natural mineral salts are prepared by using tourmaline, and natural plant salts are prepared by using gardenia or onion skin, and a natural wall cloth which is dyed by injecting pure cotton wallpaper is disclosed. In Korean Patent Publication No. 10-0445039 Although natural wallpaper, which has no harmful substances such as heavy metals, is produced by manufacturing wallpaper using guinea pigs, biotite and natural adhesives, the above literature discloses an environment-friendly wallpaper that is harmless to the human body through dyeing and post-processing after manufacturing wallpaper. It only discloses a method of manufacturing and is a problem of existing natural wallpaper. Fungi, deodorants, water resistance and visual aesthetics are not fundamentally addressed.

In the present invention to solve the problems as described above in the present invention in the form of indoor interior materials such as wallpaper, flooring, ceiling paper that realizes the natural pattern and color due to pamper pulp and natural pulp using a pampas pulp and natural pulp By using natural seaweed extract as strength enhancer, it aims to provide indoor interior materials such as eco-friendly wallpaper, flooring, and ceiling paper, which are harmless to human body.

In addition, it aims to provide indoor interior materials such as wallpaper, flooring, ceiling paper that can be utilized in a variety of construction by improving the antibacterial, deodorant and waterproof properties of the existing natural wallpaper.

In order to achieve the above object, the present invention (1) the first step of beating and treating the mixed pulp containing 70 ~ 95wt% Doc pulp and 5-30wt% of silver grass pulp, (2) the mixed pulp 100 The second step of forming a stock by adding 5 to 10 parts by weight of extract extracted by selecting one species of seaweed, E. coli and loot as strength enhancer and 0.05 to 3 parts by weight of paper dispersant, (3) It comprises a third step of molding the paper into a paper making machine and pressurized at a temperature of 160 ~ 180 ℃ so that the fibers are strongly bound to form a desired shape and design.

The Pampas grass pulp can be obtained by adding 50% to 70 minutes of sodium hydroxide solution (2 to 5wt%) and removing the foreign matter. When the concentration of the sodium hydroxide solution is too low or the boiling time is too short, the cooking is incomplete. If the concentration of sodium hydroxide is too high or the boiling time is too long, the fibers are damaged and the pulp strength and yield are lowered. Therefore, it is preferable to keep the concentration and the cooking time of the aqueous sodium hydroxide solution.

In the first step is a process of beating and treating the mixed pulp containing the pulping pulp and pampas pulp using a refiner, wherein if the content of pampas pulp is too high, the strength of the interior interior materials may be lowered and the content of pampas pulp in the above range If it is lower, it is preferable to mix Docpul 70 ~ 95wt% and 5 ~ 30wt% of duct pulp because the unique pattern and color may not be properly expressed due to pampas pulp. Wood pulp and paper pulp may be used instead of the docpulp blended with the silver grass pulp.

In the second step, a strength enhancer and a paper dispersant are mixed with the mixed pulp treated by beating to form a paper. The strength enhancer is mixed with 0.5 to 0.7 parts by weight of an acetic acid solution (10 wt%) based on 100 parts by weight of ethanol or methanol. Into an alkaline aqueous solution, one or more kinds of crushed seaweed, E. coli and loach are added, and the extract is obtained by concentrating the filtrate, which is filtered and concentrated under reduced pressure, for 4 hours.

Strength enhancers added in the manufacture of paper are typically polyamide resins, melamine resins, polyamidoamine-epichlorohydrin (PAAE), urea-and formaldehyde-based resins. resin, polyethyleneimine, and the like, but in the present invention, by using the natural seaweed extract as a strength enhancer, the same or more effects are obtained, and there is no effect of dioxins, which are harmful substances when incinerated. .

Examples of the dispersant include polyethylene oxide (PEO), carboxymethyl cellulose (CMC), cationic starch (Cation-ic starch), acetyl starch (Acethyl starch), and sulfuric acid slime (dakula solution obtained by dissociating roots of water in water). One type can be selected and used, but in the present invention, it is preferable to select and add sulfuric mucus, which is a natural substance.

In addition, if necessary, chemicals such as a sizing agent, a retention agent, an antifoaming agent, a dye, and the like may be selectively mixed. However, when the amount of such additives is too large, unnecessary cost may increase. In the case of the additive, commercially available conventional additives may be mixed, but in the case of the sizing agent, it is preferable to use alkylketen dimer (AKD).

The third step is a step of forming into a desired shape and design, by suctioning the vacuum liquid through a suction hole installed in the mold network of the papermaking machine, depositing the stock liquid in the mold network, and forming a water pressure by pressing at 160 to 180 ° C. Dry to 10% or less. At this time, the thickness of the paper is preferably adjusted according to the purpose of the interior of the interior material, to be manufactured to be at least 5 to 10mm, which is less than 5mm when the molding is not only completeness of the overall design, but also a problem that the strength is lowered.

Interior materials produced through the process is wallpaper. There are features that can be utilized in the form of floor, ceiling, etc.

Indoor interior materials manufactured in the form of wallpaper, floor paper, ceiling paper using pampas grass pulp according to the present invention are harmless to the human body and at the same time excellent in strength, antibacterial, deodorant and waterproof, and no harmful dioxin even when incinerated. Not only does it occur, but also because of the natural pattern and color that can be obtained with silver grass pulp, there is an effect that can give a visual aesthetic to the interior materials such as wallpaper, flooring, ceiling paper.
