Abstract

Method for manufacturing functional plywood using loess, activated carbon and wood vinegar

Description

Functional plywood {active board}

Currently used plywood dissipates and releases formaldehyde and organic compounds to create a harmful environment for humans, and has the disadvantage of burning easily in a fire.

The object of the present invention is to provide a plywood that can provide a beneficial environment to the human body using functional plywood and at the same time have a low emission of toxic gases and delay ignition time even in a fire.

It also aims to improve indoor air quality and create a pleasant environment.

The object of the present invention is to provide a plywood having functionalities such as reduction of formaldehyde and organic compounds using ocher, activated carbon and wood vinegar, deodorization, reduction of formaldehyde dissipation, far infrared rays, anion, and antibacterial properties.

Various furniture manufactured using general plywood is a reality that the harmful components are detected and released by the bond used to bond the sheet and sheet paper.

The present invention has been made to create a beneficial environment for the human body by using the functions of the representative far-infrared rays of an ocher, anion, and deodorization of an activated carbon, an anion, and an antibacterial and an antibacterial activity of wood vinegar.

The purpose of the present invention is to provide a method of manufacturing plywood using the functionality of ocher, activated carbon and wood vinegar while maintaining the beneficial ingredients of ocher, wood vinegar and activated carbon.

The present invention also provides a method of manufacturing a functional plywood to increase the fire resistance of the plywood and less emission of toxic gases in the event of fire.

The present invention comprises the steps of preparing ocher, activated carbon and wood vinegar, preparing a water-soluble resin and perforating plywood, mixing ocher, activated carbon and wood vinegar to the processed water-soluble resin and ocher composition on the perforated portion of plywood And characterized by the step of constructing the activated charcoal vinegar composition.

The ocher is prepared by selecting the ocher having a powder level of 200 mesh or more by drying the ocher collected at a depth of 1 meter or more underground.

Activated carbon is powdered to prepare activated carbon having a powder level of 200 mesh or more.

Wood vinegar is prepared by using activated carbon.

The step of preparing a water-soluble resin binder used in the composition is as follows. A surfactant solution is prepared by mixing deionized water and a surfactant.

Next, the resin binder solution which comprises a water-soluble binder is prepared.

At this time, deionized water and a surfactant are added to add methyl acrylate (Methyl Acid), acryl butyl (Butyl Acrtlate), methacrylic acid (Methacrylic Acid), and functional monomer (Functional Monomer).

At this time, the catalyst is mixed with a small amount of ammonium persulfate (Ammonium Persulfate) in deionized water.

Thus, after preparing a surfactant solution, a resin binder solution, and a catalyst, the prepared surfactant solution is heated.

The heating temperature at this time is 80 +/- 2 degreeC, The said resin binder solution and a catalyst are added, maintaining the temperature state at this time.

The mixed solution is reacted by slowly adding the resin binder solution and the catalyst to the surfactant solution for 3 to 5 hours.

The mixture is then aged for about 3 hours, maintaining its temperature (80 ± 2 ° C.). After the aging process is complete, a cooling step is performed.

The cooling step at this time is lowered to about 45 ℃ to cool the aged resin binder.

And the acidity (PH) of the said resin binder solution is adjusted using the after additive.

Filter the water-soluble binder adjusted pH to remove impurities.

Plywood is processed by CNC machine

The prepared water-soluble resin binder and water were diluted 1: 3.75% WT, and the mixture was added and mixed with ocher 47% WT.

The prepared water-soluble resin binder and wood vinegar were diluted 1: 4.90% WT and added and mixed with activated carbon 21% WT.

The prepared ocher and activated carbon composition is applied to the processed plywood by brush, roller and spray method and dried.

When applied to plywood and MDF, formaldehyde showed a decrease of 79.5.

Far infrared rays and negative ions also showed excellent results, and antibacterial tests showed that E. coli and Pseudomonas aeruginosa were significantly reduced.

In particular, the present invention has the effect of essentially improving the plywood dissipating harmful substances and creating a beneficial environment for the human body.
