Wood is an important raw material used by mankind and has a long history with mankind. In modern society, paper, furniture, and construction are used as important raw materials for various industries. Korea uses about 30 million m3 of wood a year, and most depend on imports. In the future, it will be difficult to procure raw materials such as forestry export regulations due to changes in international conditions such as environmental protection issues and green rounds.

To solve these problems, it is necessary to utilize resources effectively. Specifically, it is possible to utilize wood discarded from the production site to increase resource utilization and profitability. In addition, waste wood can be recycled to protect the environment. It can also effectively utilize the remaining wood after processing. In addition, resources that can be procured and recycled in the region can be utilized to reduce energy used for transportation.

It can also be used to develop building materials using wood.

Wood is a building material with many advantages and disadvantages.

Representative advantages are natural materials, environment friendly and harmless to human body. In addition, since the thermal conductivity is low, the thermal insulation effect is good. Also, the conductivity of sound or electricity is low. In addition, when the external temperature is high, the room temperature is lowered by absorbing the heat, and when the temperature is low, the room temperature is controlled. In addition, it absorbs when there is a lot of external moisture and is discharged when it is dried, which helps to create pleasant environment. In addition, it has good processability and elasticity and can be used for various purposes.

However, the disadvantage is easy to ignite. Further, deformation such as expansion, contraction, warping, cracking or the like occurs. Also, it is vulnerable to corrosion. In addition, material and strength are not uniform as a material. Also, in order to use wood, it needs to be processed and treated according to the purpose. In addition, continuous management is required.

As described above, the merits of wood can be increased and the disadvantages can be supplemented to make useful materials for living.

The object of the present invention is to provide an eco-friendly nonflammable wood chip block and panel for building materials having a flame-retardant property by mixing wood chips with cement as an adhesive agent and a solid agent and adding liquid sodium silicate and diethanolamine, .

And FIG. 9 is a view for comparing wood chips processed with special sizes and shapes and wood chips having simple cut surfaces mixed with cement.

The environmentally friendly nonflammable wood chip block according to the present invention and a method for manufacturing the same are schematically described below.

Referring to Figure 1,

First, the processing of the wood chips and the material preparing process (first step, S2)

Thereafter, chemical reaction processing and processing steps (second step, S4) of the wood chips,

Thereafter, the manufacturing process (the third step, S6) of the mixture of the high strength potantand cement,

Thereafter, a step of adding liquid sodium silicate and diethanolamine (fourth step, S8)

Thereafter, the process is largely divided into the molding and curing of the product, the drying and storing process (the fifth step, S10).

Preparation of materials and production of materials will be described below.

Principle of material selection: Use only harmless materials.

The types of materials are as follows.

Wood chips, high strength Portland cement, water, aluminum sulfate Al2 (SO4) 3, calcium chloride (CaCl2), sodium silicate Na2SiO3, diethanolamine (HOCH2CH2) 2NH.

First, the wood chips will be described in more detail as follows.

The wood chip is the main material of the environmentally flame retardant wood chip block product according to the present invention.

Wood and waste wood are used to make wood chips.

The order of production is as follows.

First, the wood chips are cut, crushed to a certain size, then screened and dried.

The manufacturing principle of the wood chip will be explained in more detail below.

Wood chips are manufactured in a long and thin form. 2 is a photograph showing a processed wood chip.

The physical principles will be further explained with reference to Figs. 3 to 7 below.

Referring to FIG. 3, the wood has a high compressive strength and tensile strength in the longitudinal direction due to the microstructure of the wood. That is, a wooden chip made in a long and thin shape, such as a matchstick, is easily broken when it is horizontally laid down and pulled up or down to break it (see FIGS. 4 and 5). However, even if pressure is applied in the longitudinal direction, it is not easily broken (see Figs. 6 and 7). That is, the transverse direction is weak to pressure, but the longitudinal direction (longitudinal direction) is strong against pressure.

That is, referring to Figs. 3 to 7, a long-shaped wooden chip is easily broken when pressure is applied laterally. Further, the long-shaped wood chips are resistant to pressure in the longitudinal direction and are not easily broken.

Using this principle, many wood chips processed in special sizes and shapes are processed into block or panel form.

If you put a lot of wood chips and make a solid shape, the wood chip will stand as a species, lying side by side or at an angle. Each of the many erected wood chips has a high compressive strength and tensile strength up and down. In addition, many wood chips lying sideways have compressive strength and tensile strength in the lateral direction. In addition, the wooden chips lying obliquely have a constant compressive strength and tensile strength in the up, down, left, and right directions.

The above principle will be described in more detail as follows. First, we examine the resistance of the wood chips to the outside in the wood chip aggregate. That is, those arranged laterally are resistant to the upper and lower pressures but resistant to the left and right pressures. In addition, those placed in a standing position are resistant to left and right pressures but resistant to upper and lower pressures. Also, those arranged obliquely are resistant to external pressure in an oblique direction. In addition, a large number of wood chips are mutually complementary to each other with respect to external pressure according to the direction in which they are placed (see Fig. 8).

On the other hand, in the environmentally flammable wood chip block according to the present invention, the water content of the wood chip will be described below.

Use a dry wood chip so that the moisture content does not exceed 20%.

If the wood chip contains too much moisture, it will adversely affect the process. Much moisture inside the wood chips shrinks during the drying process after molding, causing deformation of the wood chips, and the bonded part falls off, weakening the bonding strength.

On the other hand, the processing size and shape of the wood chips will be further explained.

It is processed to the size and shape that can best bond with cement binder and give good characteristics of material.

The size of the wood chip is 1mm ~ 10mm.

The width is 5 ~ 20mm.

The length is 10mm ~ 70mm.

However, it is not limited thereto. Modifications will be possible.

We explain more about the shape of wood chips.

The wood chips are machined to have many irregular needle shapes and fur shapes with both ends pointed and sharp.

It is aimed to increase the strength by strengthening adhesion with cement to maximize adhesion surface of wood chip. It is stronger than wood chip with cross section cut surface and has excellent strength. The wood chips are combined with the cement, which is an adhesive, to produce a shape that can produce as much air as possible.

It creates much more contact and air layers than wood chips cut in cross section, and improves the various properties of the block. Wood chips like this are more advantageous for reaction and adhesion with chemical additives than wood chips with angled section. The above shape minimizes the deformation of the wood chip by dispersing the wood chip in various directions when it deforms such as shrinkage and expansion due to the influence of humidity.

A wood chip having the above shape minimizes deformation by dispersing an external impact in various directions rather than a wood chip having a rectangular cross section against an external impact.

The above-mentioned type of wood chip does not fall off much better than a wood chip having a rectangular cross-section when an external impact is applied.

A combined form of wood chips and cement can be seen in FIG.

In FIG. 9, a combination of a wood chip and a cement combined with a long, both-end-sharpened wood chip and a cement-bonded wood chip can be seen. 10 is a photograph showing a wood chip cut into a section.

Hereinafter, a process and a method for processing wood chips in an environmentally friendly nonflammable wood chip block according to the present invention will be described.

First, the wood chips are cut to a certain size.

Then, the wood chip is cut and broken by a rotary hammer that rotates inside the drum, and the wood chip is manufactured by tearing it. This allows you to make chips with sharp, irregular shapes on both ends like needles.

Thereafter, a round wire mesh is used in the wood chip shredder drum to make the hole a certain size and to spread out a certain size.

In the meantime, the corrosion prevention treatment and the adhesive strength enhancement of the wood chip in the environmentally flammable wood chip block according to the present invention will be described.

The wood is composed of cellulose, hemicellulose, lignin and other preservatives. Cellulose is the main component of wood, accounting for about 60%. Cellulose is a component of polysaccharides. Saccharides are a major source of wood corrosion due to the feeding of microorganisms and insects.

Add the wood chips and water into the mixer, add aluminum sulfate and calcium chloride and mix well (not more than about 10 minutes). Or a mixture of aluminum sulfate and calcium chloride is added and mixed well. This can neutralize the sugars in the wood chips, mineralize the wood chips and form a film to strengthen the bond with the cement to prevent corrosion.

Wood chips and cement blocks made without the above process are quickly broken due to weak bonding strength. Also, the strength is weak and rusts quickly.

Another method is to pour a large amount of water into a large container, put wood chips and caustic soda into the container, and immerse them for a certain period of time. This method uses a lot of water, and there is a lot of water waste in difficult times due to lack of water resources. In addition, it requires a lot of space, manpower, and large containers, which increases cost and is not cost-effective. Especially, waste water treatment cost is high and there is environmental pollution problem.

On the other hand, the cement used as an adhesive and a solid agent will be described.

Cement uses high strength potantan cement.

Since the main filling material is wood chips, which are organic materials, high strength cement is used. Cement with special functions such as crude steel cement may be used depending on the surrounding environment and the condition of the wood chips.

In terms of functionality, cement hydrates to combine wood chips with strong strength and make the wood chip blocks into a solid, rigid body. The cement surrounds the wood chip and forms a constant film to keep it from burning.

The cement seeps into the wood chip, surrounds the wood chip, forms a film and mineralizes it to prevent corrosion of the wood.

It surrounds the wood chip and causes the bonding between the wood chips to make the air layer.

Aluminum sulfate (Al2 (SO4) 3) and calcium chloride (CaCl2) will be explained.

The main function is to increase the adhesive strength, realize the early strength and strengthen the strength of the product. More specifically, aluminum sulfate (Al 2 (SO 4) 3) and calcium chloride (CaCl 2) block the influence of sugar from wood chips to promote bonding with cement and realize early strength. Sugar is the most important obstacle to the bonding with cement and the realization of strength.

Aluminum sulphate (Al2 (SO4) 3) and calcium chloride (CaCl2) disinfect microorganisms and pests, remove foreign matter to prevent corrosion of wood chips, facilitate the bonding of wood chips to cement, It coagulates and removes the generated foreign matter, promotes bonding with cement, strengthens strength, and acts as a plasticizer.

Aluminum sulfate (Al2 (SO4) 3) and calcium chloride (CaCl2) can be used alone.

Aluminum sulfate (Al2 (SO4) 3) and calcium chloride (CaCl2) are mixed at a ratio of about 1: 1.

Depending on the application of the block, the condition of the wood chip and the condition of the cement, the mixing ratio is used.

Aluminum sulfate (Al2 (SO4) 3) and calcium chloride (CaCl2) play an important role in the realization of adhesion strength, solidification speed and strength of cement and complement each other.

Calcium chloride is hygroscopic and weakens the warmth and strength of the block.

In addition, the surface of the block may be whitened.

Aluminum sulfate can not compensate for the disadvantages of calcium chloride because it has no moisturizing properties.

On the other hand, liquid sodium silicate ((Na2O (Si02) n), which blocks the moisture permeable layer of the wood chip, forms a film around the wood chip. C. And it strengthens fire resistance, prevents corrosion, and makes product performance uniform.

Describing diethanolamine (HOCH2CH2) 2NH, the coagulation time of cement is shortened thereby realizing early strength. Also, a film is formed on the cement particles to prevent the adverse effect of sugar and foreign matter on the cement solidification.

Mixing and mixing ratios of the materials will be described below.

In the mixing ratio of the materials,

The compounding ratio is determined according to the kind of the wood chip, the moisture content, the use of the block and the strength thereof.

The use of the block is largely classified into a structure (a building such as a house), a partition, and a thermal insulation, and the mixing ratio of the material is controlled according to the use and the strength is controlled in the molding process.

The blending ratios for each application are as follows.

The mixing ratios based on general materials are shown in Table 1 below.

(The amount of material input is in kg)

The density of the insulation and partitioning block is 350kg / m3 ~ 500kg / m3.

The density of structural block is 500kg / m3 ~ 850kg / m3.

division Wood chip input Kg Cement input Kg Water input
Kg Aluminum sulfate, calcium chloride Sodium Liquid Silicate Input Kg Diethanolamine Kg Remarks Insulation 150kg ~ 220kg 120kg ~ 320kg 140kg ~ 320kg 2,4kg ~ 16kg 1.2kg ~ 9.6kg 0.24kg ~ 1.92kg For cubicle 220kg ~ 410kg 220kg ~ 360kg 220kg ~ 410kg 4.4kg ~ 18kg 2.2kg ~ 10.8kg 0.44kg ~ 2.2kg

Aluminum sulphate and calcium chloride should be mixed with each other or at a ratio of about 1: 1 depending on the application. The density of the product differs depending on the size of the manufactured wood chip. The density of wood chips is based on 180kg / m3 to 400kg / m3. The density of the block varies depending on the degree of compression of the mixture (mortar) of the manufactured wood chips and cement during the molding process, and the compression strength is adjusted according to the application.

The mixing process will be described below.

1) Add wood chips and water, aluminum sulphate and calcium chloride or a mixture thereof to the mixer and mix well (not more than about 10 minutes).

2) Add water, cement, liquid sodium silicate and diethanolamine to the above materials and thoroughly mix them to prepare a wood chip mixture (mortar).

The molding and curing method will be described below.

The processed mixture (mortar) is molded into a block of the required shape or pantel mold. Or concrete pouring method, it is directly injected into a mold provided on a wall and a floor.

The method of injection into the mold will be described below.

In order to put the prepared material (mortar) into the mold, vibration input (vibration), compression input (press), vibration and compression input method are used.

Allow the mixed material to fit evenly into the mold.

If the mixed material is biased in either part, the properties of the product are not uniform.

The compression strength in the molding process is explained.

Unlike aggregates such as gravel sand, wood chips are organic materials and contain moisture and are mixed with cement. Also, due to the resilience, the amount of moisture and glue and the amount of chemical additive components faded by the wood chips can vary depending on the strength of the compression. Depending on the application, the strength of compressing the mixed material should be appropriately adjusted. Excessive compression of the corrugated chip during block molding can reduce the insulation and sound insulation of the material by reducing the porosity. However, mild compression of the wood chip mixture (mortar) during the molding process affects the strength of the block.

When the material is supplied, the temperature should be at room temperature above 15 ° C.

This allows the cement to cure within a reasonable amount of time and achieve sufficient strength.

The forming mold will be described.

The mold is easily manufactured by injection and desorption of mixed materials.

The mold is mixed so that the injected material does not leak out.

During the drying of the block, the wood chips are deformed as the moisture evaporates. In this process, molds are used which are hermetically sealed and firmly fixed on all sides so that volume deformation does not occur.

Curing and peeling of the mold are explained.

Curing should be done at room temperature below 15 degrees C and below 40 degrees Celsius.

Humidity is maintained at 60% ~ 80% during the curing process.

When curing using a drying facility, the temperature should not exceed 40 degrees Celsius.

When curing using a drying facility, the humidity should be between 50% and 60%.

In the mold, the mold is removed from the molding mold after curing for a certain period of time, depending on the use of the block.

The block is not broken when the mold is removed from the mold. Do not damage the edges.

Drying and storage.

Keep out of the sunlight for 7 days after peeling the mold.

It can be transported because it has a constant strength after 7 days from the mold release.

Preferably, it can be transported and used after 14 days from the mold release.

It takes 28 days at room temperature to reach full strength.

The results and characteristics will be described.

It solves fire problems, deformation and warping which are shortcomings of wood, and weak corrosion problems. The volume of wood chips in the block is about 80% to 90%. The block contains many wood chips and pores, so it has excellent warmth and car sound.

The characteristics of the finished product will be described.

The product according to the invention is environmentally friendly. This is because they did not use harmful materials.

Also, there is no harmful bacteria such as mold, and it is hygienic.

Also, material procurement is easy. It is easy to get material around the area.

In addition, materials can be obtained cheaply by utilizing surplus materials or waste materials.

Also, waste wood is not incinerated, which is good for environmental protection.

Moreover, the production is simple.

Also, it is safe because there is little risk of fire.

Moreover, it is excellent in strength and elasticity, and is not ruptured, so it is safe from collapse and earthquake.

In addition, since a large number of air layers are secured, it is excellent in warmth and heat resistance.

It is also economical and economical for energy savings (thermal conductivity, heat transfer rate, heat resistance).

In addition, the ventilation is smooth and a pleasant environment is maintained,

Also, it has excellent soundproofing ability and can be used for interlayer noise and other purposes.

In addition, it solves fire problems, deformation and warpage corrosion, which are disadvantages of wood.
