Figure 2 is a flow chart showing a method of laying a cork flooring according to an embodiment of the present invention. 3 is a view for explaining the compaction process after the cork flooring composition application process (S150) in the method for laying the cork flooring according to an embodiment of the present invention. 4 is a view for explaining the upper surface of the cork flooring formed by the method of laying a cork flooring according to an embodiment of the present invention. 5 to 7 are diagrams for explaining the experimental results on the physical effect of the cork flooring for laying formed by the method for laying the cork flooring according to an embodiment of the present invention.

First, referring to FIGS. 1 and 2, the original ground 110, reinforcing mat 120, and water permeable layer 130 corresponding to the multi-layer flooring structure 1 formed by the method for laying a cork flooring according to an embodiment of the present invention, In order to sequentially form the solidification layer 140, the cork flooring layer 150, the raw ground compaction process (S110), the reinforcing mat formation process (S120), the water permeable layer formation process (S130), the solidification process (S140), the cork flooring material for laying It may include a composition application process (S150).

At this time, the reinforcing mat 120, the water permeable layer 130, the solidification layer 140, in particular, the reinforcing mat 120 may be omitted depending on the situation of the construction site or other conditions. However, it does not impair the main features of the present invention.

First, looking at the raw ground compaction process (S110), the original ground is compacted with a vibrating roller or a tire roller in order to increase the support force and flatness for the original ground such as concrete or soil layer at a position scheduled for road pavement as a cork flooring material for laying.

Next, referring to the reinforcing mat forming process (S120), the reinforcing mat is formed to improve the strength and hardness of the upper part of the original ground, and may be formed in a triple structure of a separable layer, a center layer, and a reinforcing layer.

Here, the separable layer uses a form of foam with a reinforcing structure, so that when the pouring work on the original ground is performed, it comes into contact with the surface of the original ground to be poured, and removes the fear of damage due to the impact applied when separating from the constructed original ground surface. The surface for this may be formed in an intaglio shape of a square grid pattern having a diameter of 20 μm to 35 μm.

In addition, the central layer is formed in a hexahedral shape with an empty inside between the separable layer and the reinforcing layer, and may be formed of a synthetic resin having reinforced strength to reinforce strength according to the empty space inside. Finally, the reinforcing layer is formed by being stacked on the back of the center layer, and is formed to have a surface area larger than the surface area of the back of the center layer, thereby reinforcing strength by impact from the outside at the back of the center layer as well as reinforcing. It can play a role of suppressing the expansion force due to concrete pouring acting on the front surface of the formwork foam 100 having a structure.

Next, looking at the process of forming a water permeable layer (S130), at least one water permeable layer and an additional auxiliary layer may be simultaneously included, and the water permeable layer and the auxiliary layer may be formed as one and the same layer, and the water permeable layer It has a function of permeating to the ground, and the auxiliary layer can have a function of retaining a certain amount of water.

Here, the configuration and number of the water-permeable layer and the auxiliary layer in the process of forming the water-permeable layer can be selectively applied according to the function of the cork flooring to be laid.

Next, referring to the solidification process (S140), a binder is added to the surface layer of the water permeable layer generated in the water permeable layer forming process (S130) to solidify.

The water permeable layer is deformed or deformed in the longitudinal/transverse direction due to the use of people and the penetration of rainwater, and to prevent this and to support the load caused by people's passage, a predetermined liquid binder is used to reinforce the water permeable layer and By filling the voids in the mat to secure support, and by securing the adhesion between the cork flooring material for installation formed in the process of applying the cork flooring composition for laying to the top (S150), the softening of the original ground and the reinforcing mat can be prevented. have.

The binder used for this is preferably filled to the bottom at a depth of 10 to 12 times the depth to be filled in the surface layer of the water permeable layer.

Such a binder additionally requires an amount of a binder 5 to 7 times the amount of the standard binder applied to the upper surface layer in order to secure a thickness of 20 mm to 30 mm for filling the surface layer of the water permeable layer. Here, the binder may be used as one or more of an asphalt binder, an emulsified asphalt, a liquid polymer, and a special cement paste.

Finally, looking at the process of applying the cork flooring composition for laying (S150), a previously prepared cork flooring composition for laying is applied to the solidified upper part. Here, after the process of applying the cork flooring composition for laying (S150), in the same manner as in step (S110), the compaction process as shown in FIG. 3 is performed manually or with a vibrating roller or a tire roller. It can increase the support power and increase the flatness.

The cork flooring composition for laying for this may be prepared by a cork pulverization process, an eco-friendly recycled material mixing process, a variable temperature paint mixing process, and a liquid-type cork laying composition manufacturing process by mixing an orb member.

More specifically, in the cork pulverization process, after the cork raw material is obtained, the cork raw material is pulverized through a grinder to produce cork chips in micro units. At this time, the diameter of each cork chip to be generated may be 200㎛ to 300㎛. Here, when the diameter of the cork chip exceeds 300 μm, when mixing with a fluorescent temperature-changing pigment corresponding to the temperature-changing paint to be described later, it causes glare even in broad daylight depending on the color of the paint, and the powder in the liquid-type cork-laying composition of the cork chip Acidity becomes weak, and if it is less than 200㎛, it may affect the manpower with PLA (PolyLactic Acid)-based raw materials in the process of mixing eco-friendly recycled materials, thereby lowering the bonding strength.

Next, looking at the process of mixing eco-friendly recycled materials, the eco-friendly recycled materials use PLA (PolyLactic Acid) composite materials. Here, the PLA composite raw material may be used by mixing PLA and PCM capsule powder. PLA (PolyLactic Acid) is a natural plant-based raw material with corn starch as the main raw material. It does not contain synthetic resins (PC, ABS, etc.) and is 100% decomposed under natural conditions, and prevents the generation of harmful substances such as dioxin and other environmental pollution. can do. PLA can be substituted for injection and extruded plastics, and it is a groundbreaking eco-friendly resin with general-purpose physical properties and can be commercialized in a full range of plastics. On the other hand, PLA has characteristics of crystallinity, natural circulation, biocompatibility, and CO ₂ reduction. PLA is an eco-friendly material capable of natural decomposition of products as plant-based raw materials, and natural decomposition is possible through the cycle process of plant-based raw materials, lactic acid, polymers, resins, products, and decomposition.

On the other hand, in another embodiment of the present invention, the weight ratio of each raw material composition constituting the PLA (PolyLactic Acid)-based raw material may be performed in a manner requested by an orderer, and may be produced based on other main raw materials.

Among PLA composite raw materials, PLA is a thermoplastic polyester manufactured by polymerizing lactide or lactic acid obtained by fermenting plants such as renewable corn, and is an eco-friendly property that is not only irrelevant to fossil resource depletion, but can be easily decomposed by landfill after use. There is this.

PLA can be prepared by polymerizing lactic acid or lactide, and if necessary, glycol compounds such as ethylene glycol or propylene glycol, dicarboxylic acids such as ethanedioic acid or terephthalic acid, glycolic acid or 2-hydroxy It may be copolymerized with an appropriate monomer such as hydroxycarboxylic acid such as benzoic acid or lactones such as caprolactone or propiolactone. And, PLA can be usually divided into D, L-PLA, meso-PLA, D-PLA, L-PLA, etc., but in the present invention is not limited to the type, the above-described PLA alone or two or more It can be mixed and used.

For this PLA, a preset ratio, that is, 10 to 15 parts by weight of PCM capsule powder (Phase Change Material Microcapsul Powder) corresponding to 100 parts by weight of the total PLA is added. Here, the PCM capsule powder includes a phase change material inside the capsule formed of a synthetic resin, and the internal phase change material may be formed of a material that repeatedly changes to solid, melting, heat energy absorption, liquid, condensation, heat energy release, and solid. Accordingly, the PCM capsule powder is mixed with the above-described cork chip to mitigate the heat island phenomenon due to low radiant heat, which is a characteristic of the cork material, in the liquid-type cork laying composition, and to provide an endothermic function according to the content of the preset PCM capsule powder. By doing so, it is possible to extend the life of the laid area formed of the liquid type cork laying composition including cork through heat exchange with the cork chips.

That is, if less than 10 parts by weight of PCM capsule powder, which is 10 to 15 parts by weight, is added to 100 parts by weight of the total PLA, the radiant heat is increased to 38°C or higher and the heat absorbing function is lowered. In this case, excessive addition of PLA to the total weight of the PLA may interfere with mixing between the binder, PLA, and cork chips.

Next, looking at the process of mixing the modified temperature paint, the modified temperature paint is formed by mixing a fluorescent pigment with a thermochromism pigment, and the thermochromic pigment reversibly changes its color based on a preset temperature. In one embodiment, the thermochromic pigment changes from achromatic color to red when heated from around 45°C, and is reduced to the original achromatic color when cooled.

Thermal discoloration in the present invention is a phenomenon representing a change in reversible optical properties, such as color change, color intensity, ultraviolet transmittance, and the like, which appear from a preset temperature when heat is applied or cooled. Using such thermal discoloration, a color change may occur at a preset temperature, and a warning requiring attention may be displayed according to a preset specific color. Here, the color change may cause a change in a very small temperature range or a gradual color change around a certain temperature. Thermal discoloration, first reported in 1871, is not explained by any one mechanism, but by several different causes depending on the rough classification of the substance. Some of these thermochromic substances, such as Organic Compounds, Inorganic Compounds, and Polymers, are actually applied in various fields, and a number of details that can be adjusted to suit the detailed mechanism and purpose of each have been revealed.

In addition, the fluorescent pigment in the present invention is manufactured to exhibit a color rendering index (Ra) of 75 or more for the discoloration of the temperature-changed paint to red color in outdoor natural light according to the mixing ratio of the fluorescent pigment, cork chip, and eco-friendly recycled material. For this purpose, the blue (B) fluorescent pigment and the green (R) fluorescent pigment are blended in a weight ratio of 4.4 to 4.7: 5.3 to 5.6, and the thermochromic pigment is 122 to 135 parts by weight based on 100 parts by weight of the total fluorescent pigment. When mixing parts by weight, the above-described 75 or more color rendering index (Ra) appeared. According to such a change in color temperature, it is possible to provide an effect for children or guardians to naturally recognize the heatwave outdoors in summer.

Next, looking at the manufacturing process of the composition for laying liquid type cork by mixing the orbs member, the first weight setting ratio for the cork chips pulverized in the cork crushing process, and the eco-friendly recycled material mixed in the mixing process of the eco-friendly recycled material. After mixing the second weight setting ratio and the third weight setting ratio to the variable temperature paint, a solvent-free binder corresponding to the fourth weight setting ratio is mixed to complete the preparation of a liquid-type composition for laying cork.

In the present invention, the solvent-free binder preferably has a total volatile organic compound content of less than 2.5 mg/m ² . It is preferable that such a solvent-free binder is selected from urethane and epoxy. In addition, a foam type binder that can additionally provide a sound absorbing and insulating function may be optionally used. In addition, such a binder preferably corresponds to the fourth weight setting ratio of the entire adhesive, and when the lower limit of the fourth weight setting ratio range to be described later is less than 0.1, the adhesive ability and workability are lowered, and the upper limit of the fourth weight setting ratio range is 0.2 If it exceeds, it is uneconomical because the noise prevention effect and cost competitiveness decrease.

Here, in the case of the first embodiment, the first weight setting ratio, the second weight setting ratio, the third weight setting ratio, and the fourth weight setting ratio are 4 to 6: 2 to 3: 0.3 to 0.5: 0.1 to 0.2. Compared to Comparative Example 1-1 and Comparative Example 1-2, radiant heat is low as shown in Table 1 below, and the permeability coefficient is high as shown in Table 2 below, and tensile strength, as shown in FIGS. 5 to 7, It can be seen that the cutting resistance and bursting strength are excellent.

Meanwhile, in Comparative Example 1-1, the first weight setting ratio, the second weight setting ratio, the third weight setting ratio, and the fourth weight setting ratio are 3:1:0.2:0.05, and Comparative Example 1-2 The first weight setting ratio, the second weight setting ratio, the third weight setting ratio, and the fourth weight setting ratio are 7:4:0.6:0.3.

Test item/classification Embodiment 1 Comparative Example 1-1 Comparative Example 1-2 Radiant heat temperature 39.8 42.5 44.2 Permeability coefficient (cm/s) 6.2 5.8 5.7

In addition, in the present invention, micro-hollow spheres may be added to the solvent-free binder in a preset ratio, that is, within 4 to 5 parts by weight based on 100 parts by weight of the total solvent-free binder. The micro-hollow sphere that can be preferably used in the present invention is a ceramic ball of a small size having a cavity space in the center, and has a shell made of ceramic material having a thickness of 200 to 300 µm, which is a preset thickness, and a pore space. When a sound wave is transmitted through the micro-hollow sphere, the opposite wave is emitted from the wall of the micro-hollow sphere, and as a result, the sound wave is trapped inside and the sound wave disappears. As such, the solvent-free binder of the present invention containing micro-hollow spheres is constructed as a flooring material, so when the impact and noise (sound waves) transmitted to the original ground such as concrete under the flooring material reach within the micro-hollow spheres, it has a damping effect against the impact. It is a place to create attenuation and noise area by refractive interference with sound waves. That is, sound isolation is achieved, so that sound waves entering the micro-hollow sphere are reduced from leaking out, thereby reducing noise. On the other hand, when the solvent-free binder is selected as the foam type, pores or voids are formed by foaming, and noise is further reduced by the same principle as the micro-hollow spheres.

In addition, the solvent-free binder used in the manufacturing process of the composition for laying liquid-type cork by mixing the orb member is mixed with a water-soluble solvent-free binder that is not harmful and has environment-friendly properties, and the solvent-free binder is less than 0.1, the lower limit of the fourth weight setting ratio. In the case of using, the bonding strength between the cork chips decreases during the construction of the flooring material using the liquid-type cork laying composition, and when added in excess of 0.2 corresponding to the upper limit of the fourth weight setting ratio, the water permeability and elasticity of the flooring material Since this decreases, it is preferably added in the range of 0.1 to 0.2 corresponding to the fourth weight setting ratio range.

On the other hand, as a second embodiment for the auxiliary member for strength reinforcement and color combination for 100 parts by weight of the liquid-type cork-laying composition in the manufacturing process of the liquid-type cork-laying composition by mixing the orb member, amphibole powder 3 to 7 parts by weight, 8 to 12 parts by weight of colored ore powder, and 12 to 13 parts by weight of a curing agent may be additionally included, wherein the ore powder is optionally colored ore powder in addition to the color of the thermochromic pigment and the fluorescent pigment It is possible to obtain the desired color of cork flooring through the color combination.

Here, amphibole powder has excellent abrasion resistance, so it reinforces the abrasion resistance of the floor material by reinforcing the weak abrasion resistance of the cork chip, which lacks abrasion resistance, and provides far-infrared radiation, antibacterial and antifungal properties, adsorption and deodorization properties, and anion emission functions can do.

Table 2 below shows the far-infrared radiation function test result table of amphibole powder.

(37℃) Emissivity (7~27㎛) 0.8791 KICM-FIR-1005 Radiation energy (W/㎡) 3.93×10 ²

In addition, in the process of preparing the liquid-type cork-laying composition by mixing the orb members as Comparative Example 2-1, the effect of the above-described auxiliary member according to the present invention was performed with respect to 100 parts by weight of the liquid-type cork-laying composition. 1 to 2 parts by weight, 4 to 7 parts by weight of colored ore powder, and 10 to 12 parts by weight of a hardener are additionally included, and as Comparative Example 2-2, on the other hand, liquid type cork is laid by mixing an orb member It is prepared by additionally including 8 to 9 parts by weight of amphibole powder, 13 to 15 parts by weight of color ore powder, and 13 to 15 parts by weight of a curing agent with respect to 100 parts by weight of the liquid-type cork-laying composition during the preparation of the composition.

Table 3 below shows the hardness and elongation as a result of a physical property test when a liquid-type cork-laying composition prepared according to Example 2, Comparative Example 2-1, and Comparative Example 2-2 is used as a flooring material. , Indicates the rate of dimensional change.

That is, the result of the physical property test of the liquid type cork laying composition to which the auxiliary member was added according to Example 2, Comparative Example 2-1, and Comparative Example 2-2 was obtained. And it can be seen that exhibits superior physical property values compared to Comparative Example 2-2.

On the other hand, by adding phytoncide particles to the auxiliary member in the range of 10 to 20 parts by weight based on 100 parts by weight of the total auxiliary member, an antibacterial function can be additionally added.

The composition for laying cork thus prepared is a natural material that generates negative ions, can be recycled when discarded, and minimizes the temperature increase in summer due to radiant heat.

In addition, the cork-laying composition improves durability compared to rubber elastic materials by processing the cork chips with an eco-friendly non-toxic resin, and there is no detection of harmful components by using a solvent-free binder, and this increases durability by inhibiting hydrolysis with a binder exclusively for cork. Made it.

In addition, by adding phytoncide to cork chips included in the composition for laying cork, it can add antibacterial function and emit scent. It is free from detection of formaldehyde and heavy metals, and it can solve problems of odor of rubber and heavy metals, and has optimal elasticity. As a result, the user's exercise fatigue can be minimized.
