Description

Functional Paving Composition Using Trachybasalt Powder

The present invention relates to a functional packaging composition comprising waste rubber powder and rough basalt stone powder. Specifically, the present invention relates to a packaging material composition having far-infrared radiation, deodorizing properties, and heavy metal adsorption properties of rough basalt stone powder by adding rough basalt stone powder to waste rubber powder.

Until recently, pavement materials installed on sidewalks, bicycle paths, trails, etc. are concrete pavement materials that are used by mixing aggregates and sand cement in a predetermined ratio and pressing them in a molding mold.

Since the concrete pavement is easily damaged by impact, it is cumbersome to continuously replace it every 1 to 5 years, and since it is not elastic, it can be easily damaged when a pedestrian falls down.

For this reason, in recent years, elastic pavements based on waste rubber such as waste tires have been widely used not only for sidewalks, walkways and bicycle paths, but also for sports facilities such as children's playgrounds and fitness clubs and sports fields.

Elastic packaging material is made by mixing waste tire powder with pigment and binder uniformly and heating and pressure molding to make it into block or mat form, or by directly installing the packaging material mixture on road surface and ground and heating and pressing with heat roller. It is becoming.

The technologies developed for waste rubber such as waste tires can be used to expand the field of use of waste rubber from road surface and pavement to other fields and uses (for example, water purification (Korean Patent Registration No. 613229) or prefabricated piping blocks (Korean patent). Registration No. 712171), etc.), and technology for efficient recycling of waste rubber (for example, Korean Patent No. 830615, a waste tire recycling device, and Korean Patent No. 788716, a waste tire grinding device, etc.) It is mainly focused on improving performance as a packaging material (for example, Korean Patent No. 645799, which is a manufacturing method of a recycled packaging material using waste tires).

To date, there have been few technologies attempting to impart beneficial functions to the human body such as far-infrared radioactive and deodorant in the utilization of waste rubber such as waste tires.

The present invention has been completed in view of imparting beneficial functionality to the human body in the utilization of waste rubber.

An object of the present invention is to provide a functional packaging composition using basalt stone powder.

Another object of the present invention to provide a method for producing an elastic block or elastic mat using the functional packaging composition.

Still another object of the present invention is to provide a road surface construction method using the elastic block or elastic mat.

Another object of the present invention to provide a packaging method of the road surface using the packaging material composition.

Other objects or specific aspects of the present invention will be presented below.

In one aspect, the invention relates to a functional packaging composition.

As confirmed in the following Examples and Experimental Examples, the present inventors uniformly mix rough basalt stone powder with waste binder and pigment with waste rubber powder, particularly waste tire powder, and melt and mold the mixture to form an elastic block and waste. Heavy metal adsorption experiments, far-infrared radiation experiments and deodorization tests of elastic blocks made of a mixture of tire powders (binders not containing rough basalt stone powder) were carried out. Compared to the elastic block, which does not contain rough basalt stone powder, it was found to have excellent heavy metal adsorption effect, far infrared radiation effect, and deodorizing effect.

In particular, the present inventors have found that the heavy metal adsorption effect, far-infrared radiation effect, and deodorizing effect of the elastic block prepared by containing the rough basalt stone powder are the results of heavy metal adsorption experiment, far-infrared radiation experiment, and deodorization experiment of the roughening basalt itself conducted as a comparative experiment. There was no particular difference.

The functional packaging composition of the present invention is provided based on these experimental results, and the functional packaging composition of the present invention is still mixed with the waste rubber powder, the binder, and the waste rubber powder having a packaging function, and still has a heavy metal adsorption effect, far infrared radiation effect, and / or the like. Or rough basalt stone powder exhibiting a deodorizing effect as an additive.

The functional packaging material composition of the present invention is used for the packaging of sports facilities such as pedestrian roads, walkways, children's playgrounds, playgrounds, fitness clubs (hereinafter referred to as "road surface") in the form of blocks, mats, etc. manufactured by heating and pressure molding, or It can be used for road pavement because it is directly installed on and heated and pressed. Whether the functional packaging composition of the present invention is manufactured in the form of a block, a mat, or the like, whether used for paving the road or directly installed and installed on the road, it will show the functionality such as heavy metal adsorption effect even in the state of being paved on the road.

In the present specification, including the claims, "functional" means heavy metal adsorptive, far-infrared radioactive and / or deodorant. Since the functionality is defined as such a complex, the functional packaging composition of the present invention can be understood as a meaning encompassing all heavy metal adsorption packaging material composition, far-infrared radiation packaging composition and deodorizing packaging composition.

In addition, in the present specification, which includes claims, the meaning of “comprising as an additive” means to include substantially less than the waste tire powder having a road surface packaging function, and to express the functionality as described above. It can be defined as meaning including in quantity. Herein, "substantially less than waste tire powder" may be defined as an amount which does not exceed the usual ratio of waste tire powder and additives necessary to exhibit the functionality as described above while maintaining its function as road pavement.

Those skilled in the art, based on the technology known in the art based on the filing of the present application and the following Examples and Experimental Examples of the present invention, while maintaining the function as a road surface packaging material within its ordinary capacity, It will be possible to determine the appropriate ratio of waste tire powder and additives that may be exhibited (although there may be differences in the degree of functionality).

For example, when the packaging composition of the present invention is made of an elastic block and used for road surface packaging, the additive is preferably included in the range of 3 to 35 parts by weight based on 100 parts by weight of the waste tire powder. If it is less than 3 parts by weight, the above functionality may not be sufficiently exhibited, and if it exceeds 35 parts by weight, the mechanical strength of the elastic block may be lowered.

Therefore, any packaging composition contains waste tire powder and rough basalt stone powder as an additive, and whether or not it is used for paving the road surface in the form of a block or directly laid on the road surface, the functionality as described above. The ratio of the waste tire powder and the additive contained therein should be taken as arbitrary as long as it is indicated.

On the other hand, it is preferable that the rough basalt stone powder contained in the functional packaging material composition of this invention is 0.5 mm or less in average particle diameter. This is because when the average particle diameter of rough basalt stone powder exceeds 0.5 mm, the mechanical strength of the pavement pavement may be lowered when the pavement composition of the present invention is used for pavement, and the functionality of the rough basalt stone powder may not be properly displayed. . The average particle diameter of the preferable rough basalt confirmed by the present inventors is 0.15 mm or less. Rough basalt stone powder with an average particle diameter of 0.15 mm or less will vary depending on the amount added to its waste tire powder, but exhibits the above-mentioned functionality sufficiently and has little effect on the mechanical strength of the road pavement. This is because the mechanical strength is improved as described later.

In the case of the waste tire powder having a road surface packaging function, the functional packaging composition of the present invention may use an average particle diameter of 0.1 mm to 12 mm. Specifically, the waste tire powder having an average particle diameter may be determined in consideration of the degree of permeability and / or elasticity to the road pavement when it is used for pavement pavement.

For example, in order to impart water permeability to the pavement, it is preferable to use waste tire powder having an average particle diameter of 8 mm or more, and to increase elasticity, for example, it is preferable to use waste tire powder having a larger average particle diameter.

The binder that can be used in the functional packaging composition of the present invention is to increase the binding force of the waste tire powder, for example, latex (latex), liquid rubber, polyurethane (polyurethan) adhesive, epoxy (epoxy) adhesive, melamine (melamine) Resins, phenol resins, urea resins, polyvinyl alcohol resins, gelatin, polyethylene oxide resins, acrylic resins, polyester resins, polyester resins, and the like, and are cured at room temperature or by heating. One can or can be used.

Meanwhile, the packaging material composition of the present invention may further include a pigment, a curing accelerator, and the like as an additive.

The pigment may be used by selecting a known suitable one according to the intended color when paving the road surface. For example, known pigments include titanium dioxide (TiO2), mercury sulphide (HgS), lead trioxide (Pb3O4), lead carbonate (PbCO3), calcium carbonate (CaCO3; Calcium carbonate), phthalocyanine blue (Phthalocyanine BLUE), diazone Diazo Yellow, carbon black, zinc oxide (ZnO), copper sulfate (CuSO 4) and the like may be exemplified.

As a hardening accelerator, in order to raise and strengthen the function of a binder, tertiary amine, tertiary amine alcohol, tertiary amine phenol, a compound of amidazole, boric acid ester, Lewis acid, an organometallic compound, etc. can be used.

The packaging composition of the present invention may include one or more of the various additives described above according to the purpose, purpose, location, type, etc. of the road surface packaging.

The various additives added at this time function as additives without impairing the properties required for the type of road pavement (for example, water permeability or the far-infrared radioactivity of the functional pavement composition of the present invention when paved on a pedestrian road). If it can be shown, the compounding quantity to the waste tire powder is not limited to a specific range.

For example, when a polyurethane-based adhesive is blended with waste tire powder for pedestrian road pavement, it is preferable to mix 2 to 15 parts by weight with respect to 100 parts by weight of waste tire powder, which is less than 2 parts by weight of polyurethane-based adhesive. This is because when it is blended, the function as a binder cannot be sufficiently exhibited, and when it is blended in an amount of more than 15 parts by weight, the permeability of the pedestrian road can be reduced.

From the same point of view, for example, the blending amount of the pigment or the curing accelerator is preferably blended in an amount of 1 to 3 parts by weight and 0.1 to 3 parts by weight, respectively, when they are blended with a petty powder for pedestrian pavement.

On the other hand, the waste rubber powder used in the functional packaging material composition of the present invention is a concept including waste synthetic rubber powder and waste natural rubber powder, such waste synthetic rubber or waste natural rubber by grinding waste tires, discarded shoe soles, etc. Can be obtained.

In addition, the rough basalt stone powder used in the present invention can be used as the sludge obtained in the process of processing the rough basalt in the building, civil works for use.

In the packaging material composition of the present invention, the waste rubber powder may be included in an amount of 60% to 90% by weight based on the total weight of the composition.

In another aspect, the present invention relates to a method for producing an elastic rubber block having functionality using rough basalt stone powder.

The method for producing a functional elastic rubber block of the present invention comprises the steps of (a) uniformly mixing the waste rubber powder, rough basalt stone powder and binder, and (b) putting the mixture into a mold and heating and pressing to form a block shape A step is made.

In another aspect, the present invention relates to a method for producing a functional elastic mat, the method of manufacturing a functional elastic mat of the present invention comprises the steps of (a) uniformly mixing the rubber powder, rough basalt stone powder and binder, and ( b) molding the mixture into a mold and heating and pressing to form a mat.

In the manufacturing method of the functional elastic block or the manufacturing method of the functional elastic mat of the present invention, the pigment may be added and mixed in step (a), and in some cases, the curing accelerator may be further added and mixed. Can be.

In addition, in the manufacturing method of the functional elastic block of the present invention or the manufacturing method of the functional elastic mat, the heating of the step (b) will usually be made in the temperature range of about 70 to 220 ℃.

In the manufacturing method of the functional elastic block or the manufacturing method of the functional elastic mat of this invention, the meaning of the said waste rubber powder, the meaning of functionality, the mixing ratio of waste rubber powder and rough basalt stone powder, an additive, such as a binder, a pigment, a hardening accelerator, etc. With respect to the addition ratio of the above, the bar described for the functional packaging composition of the present invention is effective as it is.

In another aspect, the present invention relates to a functional elastic block or a functional elastic mat obtained by the manufacturing method of the functional elastic block or a manufacturing method of the functional elastic mat.

The functional elastic block or the functional elastic mat of the present invention can be understood to be molded by heating and pressure by uniformly mixing the waste rubber powder, rough basalt stone powder and the binder, and in some cases additional formulation of the pigment and / or hardening accelerator It can be understood to be molded.

In still another aspect, the present invention relates to a method of constructing the functional elastic block or the functional elastic mat on a road surface.

The construction method of the present invention comprises the step of smoothing the road surface, and the step of constructing the functional elastic block or the elastic mat on the smoothed road surface.

In this case, the road surface may be a concrete surface or an asphalt surface, and may be a surface on which gravel and / or sand layers are installed.

When constructing an elastic block or elastic mat, it is preferable that the construction be as close as possible between the mats or blocks, and it is preferable to cut the construction so that the edge part is also as close as possible.

In still another aspect, the present invention relates to a road surface construction method of directly installing and constructing a road surface using the functional packaging material composition of the present invention.

The road construction method of the present invention comprises the steps of (a) uniformly mixing the waste rubber powder, rough basalt stone powder and binder, (b) laying the mixture on the road surface, and (c) the mixture installed on the road surface Pressing is made.

The construction method of the road surface of the present invention using the functional packaging composition directly is a method that does not use an elastic mat or an elastic block.

When the functional packaging is installed by directly laying the composition on the road surface, it is unusual that the tensile strength increases in proportion to the addition amount of the stone powder, as shown in FIG. 1. When the functional packaging composition of the present invention was heated and pressed to form an elastic block or elastic mat, the tensile strength was reduced (data not shown). Increased.

1 shows that 100 parts by weight of waste tire powder, 3 parts by weight of pigment, 23 parts by weight of binder, and 5, 10 or 20 parts by weight of stone powder may be uniformly mixed to prepare a specimen having a width of 15 mm, a length of 180 mm, and a thickness of 30 mm. It was obtained by experimenting with the method of KS M 6518 (tension rate is 50 ± 2.5mm / min) using the specimen obtained by pressurizing at 62.5kg / m ² and natural curing for 1 week.

From the results of FIG. 1, it can be seen that as a surprising result, the tensile strength increases in proportion to the increase in the amount of stone powder.

Therefore, when laying and constructing a functional packaging composition containing stone powder directly on the road surface, the road pavement not only has the functionality that rough basalt stone powder has, but also has the effect of improving the strength.

In the road construction method of the present invention directly constructing the functional packaging composition, the pigment may be added and mixed in step (a), and in some cases, a curing accelerator may be further added and mixed. .
