FIGS. 3 and 4 are graphs showing a comparison of wear amounts of conventional road pavement materials and road pavement materials according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. On the other hand, throughout the specification, when an element is referred to as "including" an element, it means that it can include other elements as well, without excluding other elements, unless specifically stated otherwise.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flowchart of a method for manufacturing a road pavement material according to the present invention. As shown in FIG. 1, the road pavement material according to the present invention has a structure in which a packing material and a carbon nano material are selected (S100, S200) by mixing them on the basis of loess or concrete, The wet method (S300) and the dry method (S400) can be performed.

On the other hand, regarding the content of the constituents of the road packaging material, the total weight of the road packaging material was used as a basis, and the amount of the solvent used in the wet method was excluded from the content standard since it was mostly removed during the curing process of the packaging material. That is, the content standard was based on the solid content of the road packaging material.

The carbon nanomaterial may include at least one selected from carbon nanotubes, carbon nanofibers, carbon nanohorns, fullerenes, nano-carbon blacks, and graphenes. The base material may be composed of loess and kaolin or may be composed of concrete do. As will be described later, the road pavement material may optionally include one or more additives selected from sunlight, wood chips, rubber chips, and the like.

The wet method (S300) includes a step (S310) of producing a liquid carbon nanomaterial by mixing a carbon nanomaterial and a dispersant in a solvent, a step (S310) of adding a conventional packing material such as loess, kaolin or concrete to the liquid carbon nanomaterial (S320) of adding the binder to the mixture (S330), and adjusting the viscosity and color of the mixture (S500).

The carbon nanomaterial plays a role of improving mechanical properties such as abrasion resistance, impact resistance, and vibration resistance of a road pavement by forming a network of a packaging material, an additive and a net structure on the basis of the base. The carbon nano material has a base on the hydrophobicity and excellent thermal conductivity Thereby improving the water-releasing ability and the warming property of the road wrapping material, thereby giving an effect of preventing icing and snowing. It is preferable that the carbon nanomaterial is added in the range of 0.1 to 10 wt% based on the total weight of the packaging material. If the content is less than 0.1 wt%, the desired effect is not expected. If the content exceeds 10 wt%, the strength of the packaging material is lowered due to the excessive volume of the carbon nanomaterial.

The solvent is not particularly limited and may be selected from distilled water, alcohol, dimethyl formamide (DMF), methyl ethyl ketone (MEK), polyol, or silicone. Dispersants for smooth dispersion of carbon nanomaterials include Triton-X, sodium dodecylsulfate (SDS), carboxy methyl cellulose (CMC), polyvinyl butyral (PVB), polybutyl acetate (PAB), cellulose acetate butyrate ester ) Or CAB (Cellulose acetate butyrate). It is preferable that the dispersant is added in a solvent for smooth dispersion when the dispersion is difficult, such as a carbon nano material, particularly a linear carbon nano material, but in the case of a particulate nano carbon black, a dispersant may not be added. It is preferable that the content of the dispersant added is in the range of 0.5 to 2 times that of the carbon nanomaterial.

As the base material, loess and kaolin emit a large amount of far-infrared rays as main components such as silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron (Fe), magnesium (Mg), sodium It acts as a promoter. The content of the loess is preferably in the range of 50 to 60 wt%, and the content of the kaolin is in the range of 10 to 30 wt%. The ratio of the proposed loess to kaolin is a ratio derived for the effect of the additive on the basis of the ratio applied to the usual packaging material, and when it is out of the range, it is difficult to realize the desired characteristics. Also, in the case of concrete composed of cement, sand, gravel, etc., the content is preferably 60 to 99.9 wt%, based on the ratio of the general packaging material to the total packaging material.

The road paving material may include at least one additive selected from sunlight, wood chips, rubber chips and the like, if necessary. Illite is added for the purpose of generating far-infrared radiation and anion, and the wood chip plays a role of absorbing and discharging moisture and absorbing shock, and the rubber chip plays a role of keeping warm and absorbing shock. It is preferable that 1 to 10 wt% of ilite and 1 to 10 wt% of each of wood chips and rubber chips are added based on the total weight of the packaging material. The addition ratio of sunlight, wood chips and rubber chips presented is a ratio derived from the function of each additive other than yellow clay and kaolin or concrete applied to ordinary packaging materials. The characteristics become difficult to implement.

The method for performing the step S320 of mechanically mixing the carbon nanomaterial, the loess, the kaolin, or the concrete as the foundation road packing material and the optionally added additives is not particularly limited, and the roll milling, Any of a ball milling, a V mixing, an attrition milling, a planetary milling, a jet milling, a strring, or a screw mixing may be used. Can be performed in a manner selected from one.

It is preferable that the mechanical mixing conditions are controlled within such a range that sufficient dispersion can be achieved within a range in which the carbon nanomaterial is not damaged. In this respect, the mechanical mixing is preferably carried out at a speed of 10 to 500 RPM for 5 seconds to 360 minutes. If the mixing speed or time is excessive, the carbon nanomaterial is damaged and the effect of increasing the wear amount can not be expected. If the mixing speed is too short, the carbon nanomaterial is not sufficiently dispersed and is present in a loose state. I can not.

After the mechanical mixing is completed, a binder is added (S330) to add the additives used in the road pavement. The type of the binder used may be a binding agent usually used in a packaging material, and is not particularly limited in the present invention. The binder content may be added in the range of 0 to 30 wt% based on the total weight ratio of the packaging material depending on the type of the packaging material (orthopedic, amorphous). If it exceeds 30 wt%, the effect of impact absorption, moisture discharge, and warming will be lost due to excessive binder.

Alternatively, the dry method (S400) may include providing carbon nanomaterials of a homogeneous or heterogeneous powder in a pre-dispersed form (S410) instead of preparing a liquid carbon nanomaterial as in the wet method (S300) , A mechanical mixing step (S420) for the mixture as well as a wetting method (S300), and a step of adding a binder (S430). This drying method (S400) is advantageous in that the process is simple and economical as compared with the wet method (S300), but has a disadvantage in terms of dispersion of carbon nanomaterials. In the dry method, the content of the carbon nanomaterial, the loess, kaolin, or concrete as a base material packing material, and the daily light, wood chips, and rubber chips as additives, , 10 to 30 wt.% Of loess, 60 to 99.9 wt.% Of kaolin, 1 to 10 wt.% Of sunlight, 1 to 10 wt.% Of wood chips, wt%, and the rubber chip is in the range of 1 to 10 wt%.

The final mixture prepared through the wet method (S300) or the dry method (S400) may be prepared in the form of a powdery or liquid amorphous packing material (S600) after adjusting the viscosity and color (S500) Or blocks. ≪ / RTI > The viscosity can be controlled by controlling the moisture according to the final shape of the road pavement or the amorphous form of the road pavement, and the pigments can be added if necessary considering the installation environment of the road pavement material. The viscosity is preferably 100 to 100,000 cP. On the other hand, the solvent used in the wet process is mostly removed during the process of adjusting the viscosity or molding the package.

FIG. 2 is a schematic view of the conventional road pavement material and the constituent materials of the road pavement material according to the present invention. As shown in FIG. 2, when compared with a conventional roadway packaging material, the roadway packaging material according to the present invention forms a network of carbon nanomaterials and net structures, including additives such as yellow earth, kaolin or concrete, By fixing the mixed components, the mechanical properties such as abrasion resistance, impact resistance, and vibration resistance of the road pavement are improved. In addition, based on the hydrophobicity and excellent thermal conductivity of the carbon nanomaterial, the water-discharging ability and the warming property of the road pavement material are improved, and the effect of preventing icing and snowing is given.

FIGS. 3 and 4 are graphs showing a comparison of the amount of wear of the conventional road pavement material and the road pavement material according to the present invention. As shown in FIGS. 3 and 4, when carbon nanomaterials are added to road pavement materials according to their real names, the amount of wear is 1/5 of that of conventional road pavement materials, indicating excellent wear resistance. As shown in the schematic diagram of FIG. 2, this is due to the effect of fixing the constituent materials of the packaging material while forming a network of carbon nanomaterials.

Example  One

The results of measuring the amount of wear of the road pavement according to the type of carbon nano material, the effect of addition, and the mixing conditions with respect to the production of the road pavement material according to the present invention are shown in FIG.

With regard to the provision of the carbon nanomaterial, the wet method is a method in which 0.1 to 10 wt% of a homogeneous or heterogeneous carbon nanomaterial is added using distilled water, alcohol, DMF, MEK, polyol or silicon as a solvent, It is added selectively according to the type of nanomaterial. In the case of linear nanomaterials which are difficult to disperse, the liquid nanomaterial is prepared by adding 0.5 to 2 times of the carbon nanomaterial content and the particulate nanocarbon black. Respectively.

Yellow lime, kaolin, ilite, wood chips and rubber chips were added to the prepared liquid carbon nanomaterials and charged into a mechanical mixing apparatus. The mixture was uniformly mixed at 10 to 500 RPM for 5 seconds to 360 minutes. In this case, the components of the mixture are 0.1 to 10 wt% of carbon nanomaterial, 50 to 60 wt% of loess, 10 to 30 wt% of kaolin, 1 to 10 wt% of ILLITE, 1 to 10 wt% 10 wt%.

The dry method relating to the provision of the carbon nanomaterial is a method of dispersing carbon nanomaterials of the same kind or different kinds in advance and then adding loess, kaolin, ilite, wood chips and rubber chips as in the wet method, . In the dry process, the process conditions for mechanical mixing and the component content of the mixture were the same as in the wet process.

For the road packaging material mixture prepared by the wet method and the dry method, the viscosity and the color were adjusted according to the kind of the final product to finally prepare the amorphous and shaped packaging material.

Table 1 shows the results of measurement of wearing amount according to the manufacturing conditions of the manufactured packaging materials.

Referring to Table 1, when carbon nanotubes, carbon nanofibers, and graphene except nanocarbon black were added to the types of carbon nanomaterials, the amount of wear was reduced compared to the conventional road wrapping materials regardless of the amount thereof . This is because, in the case of linear carbon nanomaterials, it is easier to form a net structure network than nano carbon black which is spherical particulate.

The addition of carbon nanomaterials showed excellent results in the range of 0.1 to 10 wt%. However, when the amount of carbon nanomaterial was less than 0.1 wt% and 10 wt%, the wear reduction was not observed.

The effect of the mixing condition on the amount of wear was reduced when the number of revolutions was 10 to 500 RPM and the time was 5 seconds to 360 minutes. When the number of revolutions is more than 500 RPM or the time is more than 360 minutes, the carbon nanomaterial is damaged by excessive energy and the wear amount is not reduced. When the number of revolutions is less than 10 RPM or less than 5 seconds, It was confirmed that the effect of reducing the wear amount was not exhibited because it was in a state of being not fully formed.

On the other hand, in the production of the road pavement material, the content of the road packaging material mixture components is 20 wt% of kaolin, 7 wt% of kaolin, 3 wt% of carbon nanomaterial, 5 wt% of wood chips, And the mechanical mixing condition was most preferable when the number of revolutions was 200 RPM and the time was 60 minutes.

Example  2

With respect to the production of road pavement material according to the present invention, the results of measuring the amount of wear of the concrete pavement material according to the kinds of carbon nano materials, the effect of addition and the mixing conditions for application to concrete pavement are shown in FIG. 4 and Table 2 do.

In connection with the provision of the carbon nanomaterial, the concrete alone, the ilite, the wood chip and the rubber chip were selectively added to the liquid carbon nanomaterial produced in the same manner as in Example 1 in the wet method, charged into the mechanical mixing apparatus, 10 to 500 RPM, and 5 seconds to 360 minutes. In this case, the components of the mixture were 0.1 to 10 wt% of carbon nanomaterial, 60 to 99.9 wt% of concrete, 1 to 10 wt% of ilite, 1 to 10 wt% of wood chips, and 1 to 10 wt% of rubber chips.

The drying method related to the provision of the carbon nanomaterial of Example 2 is the same as the method of Example 1, except that the same or different carbon nanomaterials in powder form are dispersed in advance, and then the concrete alone or the wood chips and rubber Chips were selectively added and mechanically mixed. In the dry process, the process conditions for mechanical mixing and the component content of the mixture were the same as in the wet process.

For the road packaging material mixture prepared by the wet method and the dry method, the amorphous and the shaped packaging material were finally prepared by selectively controlling the viscosity and the color depending on the kind of the final product.

Table 2 shows the results of measurement of the wear amount according to the manufacturing conditions of the manufactured packaging materials. The results are the same as those of Example 1.

Referring to Table 2, when carbon nanotubes, carbon nanofibers, and graphenes except nanocarbon black were added to the types of carbon nanomaterials, the amount of wear decreased compared to conventional concrete packaging materials regardless of the amount of carbon nanotubes, carbon nanofibers, and graphene . This is because, in the case of linear carbon nanomaterials, it is easier to form a net structure network than nano carbon black which is spherical particulate.

The addition of carbon nanomaterials showed excellent results in the range of 0.1 to 10 wt%. However, when the amount of carbon nanomaterial was less than 0.1 wt% and 10 wt%, the wear reduction was not observed.

The effect of the mixing condition on the amount of wear was reduced when the number of revolutions was 10 to 500 RPM and the time was 5 seconds to 360 minutes. When the number of revolutions is more than 500 RPM or the time is more than 360 minutes, the carbon nanomaterial is damaged by excessive energy and the wear amount is not reduced. When the number of revolutions is less than 10 RPM or less than 5 seconds, It was confirmed that the effect of reducing the wear amount was not exhibited because it was in a state of being not fully formed.

It is most desirable to mix 2 wt% of 1 light, 1 wt% of carbon nanomaterial and 2 wt% of rubber chips in 95 wt% of concrete, Was most preferable when the number of revolutions was 200 RPM and the time was 60 minutes.
