As the city develops, concrete structures and asphalt pavements increase, greatly deteriorating the city's natural and ecological functions. Due to the deterioration of the natural and ecological functions, it has a vulnerable structure for natural disasters such as climate change, urban flooding, etc., such as urban heat island effect. In addition, the quality of the living environment is greatly degraded due to such natural degradation, and the habitat space of living organisms is rapidly reduced, confronting serious ecological problems.

Accordingly, the Ministry of Environment has implemented the 'Economic Area Application Guideline' from December 2005, and it has functions of evaporation, fine dust adsorption, rainwater permeation and storage, soil function, habitat of animals and plants to solve ecological problems in urban space. It proposes an environmental plan that can lead to the maintenance and improvement of the natural circulation function.

The application of 'eco-area area ratio' is required in the ecosystem to create a space rich in biodiversity where various organisms can live.

Among them, the ecologically important role in rivers in the city is a waterway, and the waterway is formed of a concrete tube having a bottom and a sidewall formed in a substantially U-shaped cross section. Although the concrete water channel was able to secure safety in the dimensions even when a large amount of water flows at the time of flooding, it is made of an environment that is impossible for plants to grow.

In addition, in the banks of rivers, non-woven fabrics are laid on the surface of the river and landslides are installed to protect the land surface by resisting the water pressure and flow rate of the river water rather than the purpose of vegetation. In addition, various types of composition blocks made of synthetic resin or cement are installed on slopes of general roads to prevent loss of soil. However, such a raft block, a composition block can also plant plants in the narrow gap between the block, but there is a problem that the vegetation is impossible in the upper part of the cement block.

On the other hand, indoor air pollution (new house syndrome) due to increased use of building materials containing chemicals and increased confidentiality of houses has emerged as a social problem. Therefore, the Ministry of Environment has implemented the Indoor Air Quality Management Act for Multi-Use Facilities to regulate formaldehyde and volatile organic compounds (VOC) emitted from building materials. It is necessary to establish VOC analysis, systemic evaluation methods, establish appropriate regulatory standards, and devise future management plans.

Herbs grown on the surface greatly increase the surface strength of the board, so it has excellent strength performance as a wall material in contact with water or waterways. Use of foundation material that can replace soil function for wall, wall and roof greening It is a block-board and its manufacturing method that can be used to provide.

Another object of the present invention is to manufacture the board by adding ocher, to form a basis of the plant root adhesion system to achieve a balanced vegetation, supplement the inorganic nutrients necessary for plant growth, to extend the moisturizing time to withstand the dryer It is to create a vegetative environment.

Still another object of the present invention is to provide a sound absorbing material for interior building interiors or soundproof walls because VOC is not released since the board is manufactured by dissociating wood chips and waste paper without using formaldehyde-based adhesives.

In addition, the block-type board of the present invention is easy to germinate from the grass seed due to the high water retention and bowel properties due to expansion, shrinkage breakage, growth and early rooting of the early plants. Since the growth of natural germinated herbs has a binding force between the roots, the strength of the board is greatly improved by rooting, and the herbs grown on the surface greatly increase the surface strength of the board. Because of this, even when used as a wall material of the water contact area or the waterway, it shows excellent strength against corrosion resistance. In addition, due to the rapid greening, the sloped greening acts as a protector to reduce the drying rate of the soil by direct sunlight and reduces the scattering of the soil by weathering.

And when the ocher is added to the board of the present invention, by forming the basis of the root system attached to the vegetation due to the ocher, the plant evenly ingests the inorganic nutrients in the ocher to achieve a balanced vegetation, prolong the moisturizing time to withstand the dryer It provides the effect of creating an environment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The manufacturing method of the block-type board of this invention is demonstrated.

1 is a manufacturing process diagram of the greening block block board according to the present invention, waste paper dissociation, slurry-type pulp manufacturing (S1), wood chips, pulp mixing (S2), wet strength enhancer mixing (S3), put into the mold , Dehydration and cold pressure, wet board manufacturing (S4), thermal pressure, board forming (S5) and drying step (S6) will be included.

First, the waste paper is dissociated about 5,000 times in dissociation to prepare a slurry (S1). In this case, as the abolition, it is preferable to use the abolition of the cardboard, but not necessarily limited thereto, and also does not limit the number of dissociation.

When dissociation is completed as described above and the slurry pulp is prepared (S1), 30 to 40 parts by weight of the prepared slurry pulp is mixed (S2) to 60 to 70 parts by weight of wood chips. At this time, the wood chips are used having a particle size of 10 ~ 15mm, and the processed by-products discharged while processing the thinning material is crushed and reused. In other words, the wood chip is to use the processing by-product of wood, which is discarded waste resources, so as to be able to manufacture eco-friendly board as well as resource saving. At this time, if the particle size of the wood chip is less than 10mm or more than 15mm, there is a difference in physical strength, so to use a wood chip having the particle size as described above.

And based on 60 to 70 parts by weight of the wood chips, the slurry in the form of pulp 30 to 40 parts by weight, which is a problem that the physical strength is lowered when the pulp is less than 30 parts by weight, more than 40 parts by weight Since there is no difference in strength even if it is, use the above-described pulp by weight.

And it is environmentally friendly by recycling the waste resources discarded as a material of the vegetation-based board according to the present invention, it is possible to manufacture a board having excellent moisture retention by using wood and pulp.

And mixing (S2) the pulp in the form of slurry with the wood chips.

30 to 40 parts by weight of the slurry-like pulp may be further mixed with 5 to 10 parts by weight of ocher, and then it may be mixed with 60 to 70 parts by weight of wood chips. It is to create a balanced vegetation by ingesting inorganic nutrients evenly by establishing a foundation for rooting of vegetation roots, and to create a vegetation environment that can withstand dryers by extending the moisturizing time.

At this time, when the ocher is added less than 5 parts by weight, the effect due to the ocher is insignificant, and when there is an excess, there is a problem in the bonding force, so as to add 5 to 10 parts by weight of ocher as described above.

At this time, the addition of ocher to the pulp may be mixed by using a small amount of the retaining agent for the papermaking process to enhance the binding force. And the paper-making retention agent is not used in excess of 0.05 to 0.1 parts by weight.

When the wood chips and pulp are mixed (S2), 3 to 6 parts by weight of the wet strength enhancer is mixed with the mixture (S3). The wet strength enhancer is to increase the bonding strength of wood chips and pulp, and to improve the dimensional stability due to moisture, and is a wet strength enhancer for a papermaking process having a solid content of 12.5%. And 3 to 6 parts by weight of the wet strength enhancer is mixed, when the wet strength enhancer is less than 3 parts by weight, the effects of the above-described increase in bonding strength, dimensional stability, etc. are insignificant. This is because there is a problem of deterioration.

When the mixing (S3) is completed as described above, the mixture of the wood chip, pulp and wet strength enhancer is put into a board forming mold and cold-pressed to produce a wet board (S4). The wet board is manufactured for dehydration and prepressurization, and is cold pressed for 10 minutes at a pressure of 10 to 20 kgf / cm 2.

When the pressure is less than 10kgf / ㎠, dehydration is lowered, there is a problem of lowering the bonding force and heat loss when the pressure, the cold pressure under the above conditions.

When the wet board is manufactured (S4), the manufactured wet board is thermoformed to mold the board (S5). At this time, in the step of forming the board by hot-pressing the wet board, pressurized sequentially for 5 minutes at a pressure of 30kgf / ㎠ at a temperature of 200 ~ 220 ℃, 2 minutes at a pressure of 50kgf / ㎠ and 3 minutes at a pressure of 100kgf / ㎠ If the temperature is less than 200 ℃, there is a problem of evaporation of moisture and deterioration of board bonding strength if the temperature is lower than 200 ℃, there is a problem of discoloration as the surface of the finished product burns, the pressure using the pressure in the above-described order The purpose is to reduce the evaporation of the product and the ease of evaporation of the product during the manufacture of the product, because if the time is long or short, there is a problem that the bond strength and the surface burns discolored.

In addition, wires may be installed above and below the board in order to facilitate moisture evaporation of the wet board during the thermal pressure.

When the hot pressure board is manufactured as described above (S5), after the hot pressure step (S5) to dry for 3 to 5 hours in a hot air dryer at 100 ~ 130 ℃ to dry the moisture remaining in the inside of the board. In this case, when the drying temperature is less than 100 ° C., the drying time is long, and when the drying time is over 130 ° C., excessive energy is consumed. When the drying time is less than 3 hours, the drying is not completed, and when the drying temperature is more than 5 hours, it is not economical. .

The board according to the present invention manufactured as described above is as shown in Figures 2 and 3, comprising 60 to 70 parts by weight of wood chips 30 to 40 parts by weight and 3 to 6 parts by weight of wet strength enhancer.

In addition, it may be made by further comprising 5 to 10 parts by weight of ocher.

And as the wood chip has already been fully described above, the particle size of the wood chip is 10 to 15mm, it is preferable to use that by crushing the processed by-products discharged while processing the thin timber, the pulp to dissipate waste paper It is preferable to dissociate and use after manufacture in slurry form.

As described above, the board of the present invention is attached to concrete to create a growing environment of plants while absorbing and maintaining natural rainwater, and the like, as shown in FIGS. Even if it is used as a wall material of a place or a waterway, it exhibits excellent strength against corrosion resistance, so that it is possible to record a concrete vertical wall surface, which has been difficult to record until now.

In particular, it can be used as a base board that can replace soil function for greening of concrete retaining wall, wall greening and roof greening. For example, greening materials such as rivers, parks, playgrounds, schools, etc. It can be used as an eco-friendly natural recovery vegetation-based board to induce vegetation cover under adverse conditions such as greening material of concrete frame of river restoration.

Furthermore, the board according to the present invention serves to reduce the drying rate of the soil by direct sunlight in sloped greening, that is, to serve as a protector to improve moisture retention, and to reduce the scattering of the soil due to weathering.

In addition, when the vegetation-based board according to the present invention is installed in the vegetation mat bag, it becomes the base of the vegetation germinated externally, and even if the board is damaged by external pressure, the board is dropped by the network effect with the vegetation mat bag. It can be prevented.

In addition, the board according to the present invention is not only used for the vegetation base, but also can be used as interior building interior materials, sound-absorbing materials of soundproof walls, etc., without generation of formaldehyde and VOC, thereby providing environmentally friendly building materials. .

As described above, the present invention has been described with reference to the above embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope and spirit of the present invention. to be.
