In addition, it is preferable to polish the upper surface of the molded board to a predetermined thickness using an abrasive member.

Further, there is provided a building board using a mulberry wood, characterized in that produced by the manufacturing method of a building board using a wood mulberry.

Hereinafter, a method of manufacturing a building board using a mulberry wood part of an embodiment of the present invention will be described in detail.

According to one embodiment of the present invention, a method of manufacturing a building board using a mulberry wood part is made by mixing a powder of a mulberry wood part obtained by pulverizing the discarded waste wood part after making Hanji and forming a board shape.

At this time, the pulverized wood shredded wood powder is discarded waste wood of the abandoned bark wood to remove the bast fiber in the state of 10 ~ 50 mesh, it is preferable to adjust the moisture content to 5 ~ 10% or less in order to maintain uniformity during manufacture. .

As the binder, a phenol resin or urea resin can be used.

Here, it is good to manufacture by molding in the shape of a board after mixing 90 ~ 95% by weight of the wood shredded wood and 5-10% by weight of the binder.

In addition, when manufactured by molding to a board shape, not only the physical properties such as bending strength and compressive strength is more improved, but also the deodorization rate is more remarkably improved, far infrared rays also in order to be able to be radiated more easily in the mulberry wood 90 It is good to prepare a board by molding the board shape after mixing ~ 95% by weight and 5-10% by weight of the binder.

In order to further improve physical properties such as bending strength and compressive strength, the mulch wood flour and the binder are mixed, and then laminated on a square stainless mold on a hot plate of a thermocompressor to be adjusted to a predetermined height from 150 to 200. It is recommended to manufacture the board by thermoforming for 4 to 6 minutes at a temperature of 20 ℃ and a pressure of 20 ~ 50kgf / cm ² .

Furthermore, by being able to contact the air more smoothly, not only can the deodorization rate be improved more significantly, but also the top surface of the building board using the wood mulberry wood can be sanded to sand so that far infrared rays can be radiated more smoothly. It is good to grind to a certain thickness using a member.

The present invention recycles the wood waste wood discarded after making the Hanji, and remove the waste organic compounds generated from formaldehyde and volatile organic compounds to prevent building syndrome and new house syndrome, as well as radiate far infrared rays It is effective to promote blood circulation.

In addition, since 90 to 95% by weight of the crushed wood of the mulberry wood and 5 to 10% by weight of the binder are mixed, the physical properties such as bending strength and compressive strength are not only improved, but the deodorization rate is significantly improved. Of course, far infrared rays also have an effect that can be more easily radiated.

In addition, since the wood mulch pulverized powder and the binder is mixed and manufactured by thermoforming for 4 to 6 minutes at a temperature of 150 ~ 200 ℃ and a pressure of 20 ~ 50kgf / cm ² to improve the physical properties such as bending strength and compressive strength It can be effected.

Furthermore, since the upper surface of the building board using the wood wood part is polished to a certain thickness by using an abrasive member, the contact surface can be more smoothly contacted with air, so that not only the deodorization rate can be improved more significantly but also the far infrared ray is more smoothly. There is an effect that can be radiated.

Hereinafter, the manufacturing method of the building board using the wood mulberry of the present invention will be described in more detail with reference to the following Examples, of course, the scope of the present invention is not limited to the following examples, the technical gist of the present invention Various modifications can be made by those skilled in the art without departing from the scope of the present invention.

Example 1

After making the paper, the abandoned waste wood was collected at the Hanji plant located in Jeonju, Jeonbuk, and then pulverized into 18-mesh shredded wood, and the water content was adjusted to 8% or less.

Kolon Oil Co., Ltd. powdered phenol resin (KNB-100PL) was used as a binder.

98% by weight of the wood shredded wood and 2% by weight of the binder was mixed, followed by thermoforming for 4 minutes at a temperature of 150 ° C. and a pressure of ²⁰ kgf / cm ² to prepare a building board of Example 1.

[Example 2]

Unlike Example 1, 95% by weight of the wood shredded wood and 5% by weight of the binder were mixed, followed by thermoforming for 4 minutes at a temperature of 170 ° C. and a pressure of 30 kgf / cm ² to prepare a building board of Example 2.

Example 3

Unlike Example 1, 90% by weight of the crushed wood mulberry wood and 10% by weight of the binder was mixed, followed by thermoforming for 5 minutes at a temperature of 190 ℃ and a pressure of 30kgf / cm ² to prepare a building board of Example 3.

Example 4

Unlike Example 1, after mixing 85% by weight of the crushed wood mulberry wood and 15% by weight of the binder, the building board of Example 4 was manufactured by thermoforming for 6 minutes at a temperature of 200 ℃ and a pressure of 50kgf / cm ² .

Example 5

Unlike Example 1, after mixing 95% by weight of the crushed wood mulberry and 5% by weight of the binder, and dried by thermoforming for 6 minutes at a temperature of 200 ℃ and a pressure of 50kgf / cm ² , and then sand the top surface with sandpaper To prepare a building board of Example 5 having a thickness of 1.1cm.

Deodorization rate, far infrared radiation, formaldehyde and volatile organic compound radiation and bending strength of the building boards of Examples 1 to 5 thus prepared were measured.

At this time, each measurement was carried out on the 20 building boards of Examples 1 to 5 after measuring the average value.

[Deodorization rate measurement]

Deodorization rate of formaldehyde and volatile organic compounds was measured in accordance with KICM-FIR-1085 at the Korea Institute of Construction Materials, and the results are shown in Table 1.

[Table 1] Deodorization rate measurement results

Example 1 Example 2 Example 3 Example 4 Example 5 Average deodorization rate
(%)
80.6
90.3
87.1
81.9
88.3

Thus, the average deodorization rate of the building boards of Examples 1 to 5 was measured to be 80.6% or more.

This is due to the increase in the pore structure of the building board of Examples 1 to 5 as the mixing ratio of the wood shredder of the mulberry increases, the deodorization rate for formaldehyde and volatile organic compounds increased,

As the mixing ratio of the binder increased, the deodorization rate of formaldehyde and volatile organic compounds increased, and the upper surface of the building board of Example 5 was sanded to a thickness of 1.1 cm using sandpaper to formaldehyde and volatile organic compounds. Deodorization rate was increased.

[Far Infrared Radiation Measurement]

Far-infrared radiation measurements were measured using a FT-IR spectrometer in the range of 5 ~ 20㎛ at 40 ℃ based on KICM-FIR-1005 of the Institute of Construction Materials, the results are shown in Table 2.

Table 2 Far-Infrared Radiation Measurement Results

Example 1 Example 2 Example 3 Example 4 Example 5 Average
Far Infrared
Emission amount (%)
0.891
0.897
0.895
0.892
0.899

Thus, the average far-infrared radiation amount of the building boards of Examples 2, 3 and 5 was measured to be 0.89 5% or more.

However, the average far-infrared radiation dose of the building boards of Examples 1 and 4 was 0.892% or less, which was lower than that of the building boards of Examples 2, 3 and 5.

This is because the average far-infrared radiation rate increases as the mixing ratio of the mulberry wood pulverization increases, but the average far-infrared radiation decreases as the mixing ratio of the binder increases, and the far-infrared radiation increases as the thickness of the upper surface of the building board increases.

[Measurement of Radiation of Formaldehyde and Volatile Organic Compounds]

Radiation measurements of formaldehyde and volatile organic compounds were measured in accordance with KSM ISO 16000-3 (2003) and KSM ISO 16000-6 (2004) using a 20 liter small chamber (model ADTECH, Japan) at NICEM at Seoul National University. The results are shown in Table 3.

[Table 3] Radiation Measurement Results of Formaldehyde and Volatile Organic Compounds

Average
Radiation Example 1 Example 2 Example 3 Example 4 Example 5 (mg / m ² · H) HCHO TVOC HCHO TVOC HCHO TVOC HCHO TVOC HCHO TVOC 0.004 0.281 0.004 0.074 0.005 0.077 0.006 0.285 0.004 0.075

※ HCHO represents formaldehyde and TVOC represents total volatile organic compounds.

As described above, the average TVOC of the building boards of Examples 2, 3 and 5 was measured to be 0.077 mg / m ² · H or less, and the average TVOC of the building boards of Examples 1 and 4 was 0.281 mg / m ² · H. It was measured highly above.

The average HCHO of the building boards of Examples 1 to 5 was constantly measured in the range of 0.004 to 0.006 mg / m ² · H.

This is because the binder is mixed in the building board of Example 2, 3, 5, 5% by weight and 10% by weight, respectively, in particular, the upper surface of the building board of Example 5 is polished to 1.1cm, the form present in the binder This may be due to the increased deodorization rate of aldehydes and volatile organic compounds.

[Bending Strength Measurement]

Evaluation of the flexural strength test was measured the average flexural strength of the building board of Examples 1 to 4 by using a flexural strength test, the results are shown in Table 4.

[Table 4] Average bending strength measurement results

Average flexural strength Example 1 Example 2 Example 3 Example 4 kgf / cm ² 81 87 86 82

Thus, the average bending strength of the building boards of Examples 2, 3 86kgf / cm ² It was measured as high as above, and the average flexural strength of the building boards of Examples 1 and 4 was measured as low as 82kgf / cm ² or less.

It is believed that the flexural strength also increased as the mixing ratio of the binder increased.
