Processed cork-chips for elastic pavement and construction method of elastic pavement by using cork chips}

The present invention is to solve the problems of the elastic flooring material of the existing synthetic material, and to relate to the process and chip construction for elastic packaging using an elastic flooring material of the natural material that is environmentally friendly and excellent elasticity than the existing elastic flooring material and improved friction strength .

In particular, the present invention relates to the manufacture of elastic packaging materials and the construction of elastic packaging materials using the warmth and resilience of the cork, and is not limited to the use of the existing cork, by inhibiting the water expansion of the cork, without altering the external weather conditions, the strength and permeability It is a technical field to reduce deformation by overcoming urethane resin on the surface of natural cork to maintain its properties, and to overcome the defects of the product itself even when used as a packaging material in the field. In the field of technology.

In addition, the present invention is based on the water permeability of the optimized permeability structure and the elasticity and warmth of the cork as a method for overcoming the problems of urethane and rubber-based elastic packaging material based on the technology of the applicant Patent No. 0497565.

The present invention relates to a method for manufacturing and constructing an elastic pavement material using cork (powder), which is a natural material, on the floor of an indoor stadium, a school corridor, or a sports facility in a park. In order to overcome the problem, it proposed a method to alleviate the expansion of natural cork so that it would not be deformed even when it was installed on the open air, and solved the problem of maintaining the cork itself airtightness and forming the pores of particles to permeate will be.

Existing elastic flooring material becomes hot under the influence of the sun in the summer, adding to the urban heat island phenomenon, and when snow falls on existing structures that are not pitched in winter, the melting time is long, which is a risk factor for pedestrian safety.

In addition, in order to maintain elasticity that meets the environmental standards of children's playgrounds, a huge cost is required to achieve the desired elasticity and to cope with the adverse effects on the human body due to residual ingredients, which are synthetic materials. Was not developed.

In addition, the general elastic packaging material has a large specific gravity, so there is little jungle phenomenon during construction, there is no problem in the construction, but the cork has a low specific gravity, there is a problem to pay attention to mixing and construction.

In order to solve these problems and to solve the shortcomings of the existing elastic packaging materials and to propose an environmentally friendly way, the existing elastic flooring material generates deadly poisonous gas to the human body in the event of fire and heats the trees by radiating heat when exposed to sunlight. Although it contributes to the urban heat island phenomenon, it is mainly used for school or park playgrounds by alleviating the movement shock caused by the convenience of walking and elasticity.

In the case of the permeable packaging material that is currently used, there is little air gap and its own elasticity plays a role of blocking the permeability gap, and fine dust or other contaminants get stuck in the air gap, so the drainage performance is drastically deteriorated. Leads to an impossible state.

As an alternative to overcome the shortcomings of this elastic packaging material, it is a natural material and is used as a bottom elastic packaging material using cork, which has been used continuously since ancient times. Existing cork products are compressed into planks and are not permeable and have uneven floors. Could not be used.

In addition, even if the volume of the expansion caused by the expansion of the water expansion, swelling and the phenomenon of the seams that occur due to the phenomena of the expansion and expansion, so that the use of the walkway playground park playground exposed to the outside is like a dream.

Cork is a natural material that is familiar with nature and has many pores in its own way, so it can be suggested as a way to solve various problems.

Cork has a swelling due to moisture, and when used without processing, swells due to volume expansion in rainy weather and separates from the bottom.

Cork is inflated with moisture and used as a lid for airtight containers or as a raw material for products that require airtightness such as waterproofing or gaskets by using the airtightness of the cell itself. It emits negative ions and far-infrared rays and has been used as a beneficial material for the human body.

 Taking advantage of these characteristics, the surface of the existing elastic flooring due to the increase in the surface temperature due to the increase in the temperature caused by the rise of the temperature, and further damage to the plant heat, a new replacement is needed.

Applicant Patent No. 0497565 of the present applicant is constructed in a permeable structure in the construction of the elastic packaging material, so that the pitch of the rainwater is smooth, not only the role of replenishing the groundwater, and also plays a role in flood prevention.

However, due to the characteristics of the polymer compound that is applied to the surface layer, it provides the cause of city temperature rise and hardens with long-term use, and loses its inherent elasticity as time passes. It sinks in rivers and remains a cause of environmental destruction.

An object of the present invention is to solve the problems as described above, to maintain the performance of the permeability structure using the cork on the basis of the permeability structure and to serve to alleviate the urban heat island phenomenon by maintaining the room temperature surface It is to provide an elastic packaging processing cork chip and construction method using the characteristics of the cork.

The present invention also processes cork, which is an alternative to solve various problems such as impermeability and post-deformation, alleviation of urban heat island phenomenon caused by heat dissipation of existing elastic packaging materials, and prevention of sliding accidents due to freezing of winter surfaces. And when cork-packed, it is lighter than the existing material, so it suggests how to solve the problem during construction.

In order to achieve the above object, the processed cork chip for elastic packaging according to the present invention comprises the steps of a) mixing a urethane resin with a cork chip using a stirrer, b) spreading the stirred mixture widely and curing for 2 to 5 hours, c A) pulverizing the cured mixture using a grinder, d) further adding a urethane resin to the pulverized mixture, and stirring; and e) pulverizing the re-stirred mixture using a grinder. .

When the hardening of the surface to the extent that it does not push when the second step of pressing with a constant temperature roller, and n) to provide an outdoor packaging method comprising the step of coating the surface with a urethane resin.

By forming a cool surface to reduce the heat island phenomenon in the city, the groundwater is raised by a smooth permeation without causing any thermal damage to the plant, and it enables a healthy life under the influence of negative ions and far infrared rays emitted from natural materials.

In addition, it can provide a comfortable feeling to people by providing natural colors such as soil on roads or walkway playground spaces that lose natural beauty due to artificial colors.

In addition, the existing elastic packaging material is exposed to ultraviolet rays, cured and discolored to damage the aesthetics and lose the original elasticity does not act as an elastic packaging material, but the natural elastic packaging material of the present invention continuously maintains elasticity and reduces environmental pollution without damaging the aesthetics by discoloration. Once collected, 100% recycling is possible.

These and other objects and novel features of the present invention will become more apparent from the description of the present specification and the accompanying drawings.

1 is a flow chart illustrating the steps of manufacturing a packaging cork chip for packaging according to the present invention, Figure 2 is a flow chart illustrating a packaging method using a packaging cork chip for packaging according to the present invention.

First, the concept of the present invention will be described.

The present invention can be installed in a structure consisting of a lower base layer, a primer layer, a cork elastic layer mixed with a binder, an upper coating layer in the case of indoor packaging using cork, and in the case of floorboards having cracks or gaps in the bottom, Attach the reinforcing mesh made of fiber with a binder, mix the cork powder with a predetermined one-component urethane-based binder on the upper part of it, go through the flat work using the primary roller, and press it using the secondary roller according to the intended use. give.

Conventional generalized elastic packaging material is opposed to the trend of pursuing well-being mainly with rubber series or petrochemical products, and it can be used as a natural material suitable for indoors requiring elasticity that existing elastic packaging materials could not digest. It does not rot and does not generate toxic gas during fire, and it has a great advantage as indoor flooring material because it has excellent performance in insulation as well as sound insulation and dustproofing.

Although the use of cork increases due to these advantages, the disadvantages of the conventional cork are that the surface strength is weak and the method of adhering the tile-shaped board-shaped products manufactured at the factory to the floor may cause a fall or a gap. Cork powder can be mixed with the binder in the field to be installed in one piece, there is an advantage to implement the one-piece floor.

The process of cork with good material and excellent elasticity is carried out two times to reduce deformation by coating natural cork chips with urethane resin that is harmless to the human body, and the coated cork powder is again used with urethane resin or urethane binder. By constructing and mixing in the field, construction of permeable and eco-friendly elastic packaging material to reduce the urban temperature rise due to radiant heat, prevent sliding accidents caused by freezing in winter, and contribute to groundwater cultivation through smooth permeation. think.

Method for producing a packaging cork chip for packaging according to the present invention is as follows.

The urethane resin is mixed with cork, 10-15% of urethane resin and 85-90% of cork chip by weight, and mixed in a stirrer at a speed of 80 times per minute in a stirrer. And harden for 2-5 hours.

At this time, a curing accelerator may be used for rapid curing.

The cured cork chips are ground to a size of 5-7 mm using a grinder, and then mixed with 85 to 90% cork chips and 10 to 15% urethane resin by weight using a stirrer. It is preferable that the grinding | pulverization at this time consists of 2-3 mm size.

Repeating the above method twice, urethane resin is evenly wrapped on the surface of the cork chip than repeated one time, less water penetration, less strain after construction.

The degree of deformation can be expressed as follows.

   Mixing ratio       10:90        15:85        20:80        25:75   Initial state        4.5%        4.5%        4.5%         4.5%   1 time mixing        2.00%        1.8%        1.5%         1.1%   2 times mixing        0.3%        0.3%        0.2%         0.2%

According to the table, the deformation varies depending on the mixing of the urethane resin, but the cost of the urethane resin is high, and after mixing and grinding, it is mixed again with the urethane binder at the time of construction, so it is not necessary to add a lot of expensive resin and to mix the minimum amount of 10% You can make the desired elastic chip by mixing only.

The volume change test was conducted by the method of ASTM F 104: 1995 with a sample size of 3 cm x 3 cm.

The recovery test in parallel with the above test showed an excellent recovery rate of 99%. Recovery measurements were taken 5 minutes after compression.

In order to construct the above-made cork chip, a permeable layer formed of crushed stone or existing concrete, asphalt, a pitcher cone, or a sidewalk block can be installed, but a permeable layer using crushed stone is most reasonable.

As an indoor packaging method, the process of the process cork chip and the urethane binder in a ratio of 30 to 35% and 65 to 70% by weight, respectively, laid and laid down, and then planarized, the laid process cork chip mixture with a constant temperature roller first Pressing step, when the hardening of the surface 20 ~ 30% after the compaction (this state means that the hardening occurred so as not to be pushed when selecting the surface with the roller) the second step of pressing with a constant temperature roller And, it is preferable to proceed to the step of coating the surface with a urethane resin.

However, when the cork has a low specific gravity, when it is applied to existing concrete, asphalt, pitcher cone, or sidewalk block, it is severely pushed during construction, which reduces efficiency. Before spraying the cork chip of about 5mm size, it should be cured and make a protruding surface to prevent the rolling from the surface.

Specifically, applying a primer and sprinkling the processed cork chip to form a protruding surface for anti-rolling, after the primer is cured, the processed cork chip and the urethane binder are mixed in a ratio of 30 to 35% and 65 to 70% by weight, respectively. Step of laying and then flattening, pressing the laid process cork chip mixture with a constant temperature roller first, when the surface hardening occurs 20-30% after the compaction When hardening does not push when the state occurs) The second step of pressing with a constant temperature roller, and the step of coating the surface with a urethane resin to prevent the phenomena, it is possible to stably fix the processed cork chip.

However, when the construction using the crushed stone, the phenomenon of the jungle is alleviated, so that the cork chips mixed at once can be installed immediately.

In this case, spraying 1.2 kg of urethane binder per ㎡ on the surface of the crushed stone, the surface of the crushed stone is covered with the urethane binder, and the urethane binder is 45-50% and 50-55% of the weight of the cork chip without the urethane binder. You may mix by mixing ratio and may apply to the upper part of a crushed stone.

In this case, a large amount of urethane surrounds the cork chip, making it difficult to infiltrate moisture, and due to the large amount of urethane, expansion does not occur and smooth drainage is achieved through the lower crushed stone.

At this time, if you install a separate reinforcement mesh on the top of the crushed stone and install the cork chip, as in the case of installing cork on the floor with the space below, the cork chip will not be deformed, so there will be no cracking even if you use it for a long time. .

In the case of cracks in the floor or floorboards with gaps in the room, the reinforcing mesh is firmly attached to the lower part using a primer and an adhesive with a binder, and cured, and then cork powder is mixed with a predetermined one-component urethane binder. After the flat work using the first constant temperature roller, it is preferable to press using the secondary roller according to the intended use.

In addition, in order to eliminate the smell of the binder and to smell, adding a fragrance 0.5% by weight to the binder can be mixed to make a fragrant elastic packaging cork chip.

In addition, two pressing processes to increase the density of the package should be performed two times after the cork has high elasticity and resilience, and the binder is cured for about 20 hours by about 1 hour.

On the other hand, when the cork is used only by processing the chip, the weight ratio of the cork chip and the urethane binder is mixed by 45 to 50% and 50 to 55% and packaged by the above method.

At this time, the mixing is carried out at a rotational speed of 80 or more times per minute. This is because the cork is light so that the mixing speed should be set fast. In addition, it is possible to prevent the bubble phenomenon that occurs when the cork, the binder is agglomerated due to inadequate mixing.

In this case, the consumption of the binder increases, but there is an advantage that does not go through processing.

The present invention is applied to the processed cork chip for elastic packaging and its construction method.
