The present invention relates to a colored elastic pavement body suitable for use in golf course passageways, which has excellent functionality, fashionability, workability, and economic efficiency. Various types of polyurethane-based elastic pavements using rubber chips as an aggregate have been developed. However, most of these are aimed at improving physical properties such as elasticity, walking ability, and maneuverability.
Recently, in addition to this characteristic, emphasis has been placed on a comprehensive design that balances the interests of people, the environment, and economy, and a new type of resilient pavement is in demand. The inventors of the present invention comprehensively examined what type of resilient pavement would be required in the new era from the aspects of functionality, functionality, economy, and workability, and made comparisons by making improvements and devising. Succeeded in achieving these objectives with a simple structure,
This completes the present invention. That is, the present invention uses particularly selected aggregates as aggregates.
Using granular rubber chips of 0.5 to 5 mm, one-component polyurethane as a binder, and pigment as a coloring agent,
Adding a rubber color preservative and a curing accelerator to this, and assuming that the granular rubber chips and one-component polyurethane are mixed together as 100, the weight ratio is 75 to 70.
Colored elastic pavement for golf course walking paths made by uniformly mixing the mixture in a ratio of 25 to 30 and curing it by a conventional method, and acrylic resin and tolylene diisocyanate on the surface of the elastic material cured as above. The present invention relates to a colored elastic pavement for golf course walking paths, which is provided with a surface treatment layer consisting of the following. In the present invention, granular rubber chips of a particularly selected size, a rubber color fixing agent, a pigment, and air are organically dispersed in a polyurethane binder from the bottom to the surface of the pavement. Although it has an extremely simple structure and composition, it has the following characteristics that make it ideal for use. It has moderate strength and excellent durability.
The specially selected size of granular rubber chips and one-component polyurethane are blended in a specific ratio, so the rubber chips are evenly dispersed with air in the polyurethane, providing comfortable cushioning for long walks. , I don't feel any fatigue when using it. On the surface of the pavement, polyurethane resin is bonded to cover the rubber chips, resulting in a moderately rough surface that has an anti-slip effect and an anti-light reflection effect. One-part polyurethanes provide a more uniform mixture than two-part polyurethanes, and therefore provide a more homogeneous pavement. The color of the rubber chips is fixed with a color fixing agent, and the pigments are evenly dispersed inside the pavement, so even if a part of the chip is damaged and the inside is exposed, it still shows beautiful color and there is no color unevenness.
Rubber color fixing agent has the effect of erasing the black color of rubber.
By using a color fixing agent, the amount of pigment can be reduced and a more economical and cheaper elastomer can be provided. By providing a surface treatment layer made of acrylic resin and tolylene diisocyanate, ultraviolet ray resistance and ozone resistance are increased, resulting in even more excellent durability. It can be constructed on-site to suit the layout and can be used the next day. Even if repairs are necessary, they can be easily repaired. In the present invention, rubber chips in the form of particles of 0.5 to 5 mm are used. If rubber chips with a diameter of 0.5 mm or less are used, there will be no voids inside the resilient pavement, resulting in a so-called clogging phenomenon, which will provide strength but reduce elasticity, and with rubber chips of 5 mm or more, brittleness will occur. It gets bigger and cannot maintain its strength,
In either case, it cannot be used as a resilient pavement that achieves the object of the present invention. In particular, 1~
When 3 mm granular rubber chips are used and the ratio of rubber chips to one-component polyurethane is adjusted to 75 to 70 parts by weight to 25 to 30 parts by weight of urethane, the best elasticity, strength, walkability, etc. are exhibited. Therefore, it is ideal for golf course walking paths that require ultra-local elasticity and compressive strength due to spikes, etc. If the urethane content is higher than the above ratio, the urethane will foam and become sticky, and if the urethane content is less than the above ratio, it will be more susceptible to physical stimulation due to spikes, and other properties such as durability will be affected. descend. When using one-component polyurethane, it is easy to blend the components, it cures quickly, and it imparts great flexibility. Coupled with the mixing ratio of , the product of the present invention provides a resilient pavement with excellent usability. The rubber chips are most preferably tire rubber, but other vulcanized rubbers may also be used. Calcium carbonate and titanium oxide are also used as rubber color preventive agents, which can reduce the amount of pigment used by about 40%. In terms of vivid colors, in the present invention, the rubber chips, rubber color preservative, coloring agent, and urethane are organically dispersed and constituted, so the coloring effect of the coloring agent is large, and moreover, it can be applied over the entire surface of the pavement. Gives bright and vivid color. The color is green,
There are various types such as brown and blue, and depending on the design requirements of the construction site, it is possible to select the most suitable color by mixing not only one type but also two or more types of pigment. Depending on the purpose of use, it is also possible to use different functional colors. Most of the conventionally known rubber chips are black or black-gray, which is the original color of the rubber chips, and this cannot be called a colored pavement. In addition, there is a structure that has a coating layer containing a coloring agent on the surface of the pavement for coloring, but in this case, the elastic layer under the coating layer is a layer that has the original black color of rubber, and due to some accident, If the surface is scratched or chipped due to continuous use, the underlying color will appear and color unevenness will easily occur. In addition, in the present invention, the elastic material is the color layer, but
This method requires further coating of a color layer on the surface of the elastic body, and is inferior in terms of short-term, easy construction, and economical construction. Although the pavement body of the present invention can be put to practical use as a structure as described above, it is further coated with a surface treatment layer consisting of an acrylic resin and tolylene diisocyanate, preferably at a rate of 200 to 300 g per 1 m 2 of the elastic body. When formed, variations in the surface of the elastic body can be prevented and the surface strength can be further maintained. The acrylic resin and tolylene diisocyanate may be blended in any ratio from the viewpoint of workability, but especially when blended in a weight ratio of approximately 1:1, it is suitable for spraying with a spray gun. Tolylene diisocyanate is not only used as a solvent for the acrylic resin, but also serves as an adhesive between the surface treatment layer and the elastic layer. Part of this material evaporates and escapes during construction, so the proportion in the surface treatment layer usually changes between the initial blending and after construction. Further, by providing an acrylic layer, it is possible to expect the effects of preventing deterioration of the polyurethane resin due to ultraviolet rays and ozone generation, resulting in a pavement with excellent light resistance. Moreover, the acrylic layer is transparent and reflects the color of the polyurethane layer. The pavement according to the present invention is constructed and formed as follows. First, surface treatment is performed. Since the pavement of the present invention is mainly constructed on-site, it is susceptible to the influence of the substrate in such cases, so it is particularly necessary to adjust the substrate, such as leveling and cleaning the substrate. Next, a primer is applied. Then, a uniformly mixed mixture of rubber chips, rubber color fixing agent, pigment, curing accelerator, and one-component polyurethane is applied, pressed with a rubber spatula, trowel, or preferably a heated hand roller, and cured and finished. . In this way, the intended colored elastic pavement can be formed with extremely simple construction, and can be used the next day after construction. If necessary, a surface treatment layer made of acrylic resin and tolylene diisocyanate is provided by spraying, brushing, etc. Next, the present invention will be explained in more detail with reference to Examples. However, the present invention is not limited to these examples. Example 1 23.4 parts by weight of a one-component moisture-curable urethane prepolymer with NCO terminals (hereinafter referred to as MDI prepolymer) prepared by reacting diphenylmethane diisocyanate with a polyol was thoroughly mixed with 1.8 parts of calcium carbonate in a mixer in advance. 70.1 parts by weight of rubber chips of 1 to 3 mm (corresponding to a weight ratio of 25.1 urethane prepolymer to 74.9 parts of rubber chips when the mixture of both is 100), 3.4 parts by weight of iron oxide, and 1.3 parts by weight of a metal catalyst curing accelerator. Add and mix well.
Apply this mixture at 15.2 kg per 1 m 2 on the asphalt pavement base that has been pre-primed.
After leveling it by hand, it was lightly compacted with a roller and left alone. After about 8 hours at a temperature of about 15°C, a beautiful brick-colored elastic pavement was obtained. The physical properties of this elastic body are tensile strength of 16Kgf/cm 2 and elongation.
The tear strength was 14 Kgf/cm 2 and the impact resilience was 48%. Example 2 25.3 parts by weight of MD1 prepolymer, 68.4 parts by weight of 1-3 mm rubber chips (when the mixture of both is taken as 100, the weight ratio is 27.0 parts of urethane prepolymer to 73.0 parts of rubber chips), 5.6 parts by weight of red pigment (3.9 parts by weight of iron oxide) and 1.7 parts by weight of titanium oxide) and 0.7 parts by weight of a metal catalyst curing accelerator were thoroughly mixed. Apply this mixture at 14.2 kg per 1 m 2 on the primer-treated asphalt concrete base.
A colored elastic pavement was obtained in the same manner as in Example 1. The tensile strength of this elastic body is 18Kgf/cm 2 and the elongation is
127%, tear strength 15Kgf/cm 2 , impact resilience 47%
It was hot. Example 3 26.2 parts by weight of MDI pre-prepolymer, 61.4 parts by weight of 1-3 mm rubber chips (when the mixture of both is taken as 100, the weight ratio is 29.9 urethane prepolymer to 70.1 parts rubber chips), and 8.8 parts by weight of green pigment consisting of iron oxide and phthalocyanine green. Part by weight, calcium carbonate
2.9 parts by weight and 0.5 parts by weight of the metal catalyst curing accelerator were thoroughly mixed. 13.7Kg per 1m2 of this mixture was applied to the primer-treated asphalt pavement base.
was applied, smoothed by hand, and then lightly rolled with a roller. In summer, a beautiful green colored elastic pavement was obtained in about 3 to 4 hours. The tensile strength of this elastic body is 20Kgf/cm 2 , the elongation is 150%, and the tear strength is
The impact resilience was 16Kgf/cm 2 and 45%. Example 4 A mixed solution consisting of 50 parts by weight of acrylic resin and 50 parts by weight of tolylene diisocyanate was sprayed onto the surface of the elastic body obtained in Example 3 at a rate of 250 g per 1 m 2 of the elastic body using a spray gun, and the surface was dried. A treated layer was formed. This elastic body exhibits physical properties equivalent to or better than those of Example 3. Furthermore, compared to the elastic material of Example 3, which began to discolor and fade around three months after construction, the same phenomenon began to occur with the material of this example after 6 to 7 months, and a significant improvement in light resistance was observed. It will be done.
Furthermore, the rubber chips were less likely to fray and become scattered than in Examples 1 to 3. Comparative Example 1 71.9 parts by weight of 1-3 mm rubber chips (equivalent to 23:77), 3.5 parts by weight of iron oxide, 1.8 parts by weight of calcium carbonate, and 1.4 parts by weight of a metal catalyst curing accelerator were added to 21.4 parts by weight of MDI prepolymer. The mixture was thoroughly mixed and applied in an amount of 15.0 kg per 1 m 2 to obtain a colored elastic pavement in the same manner as in Example 1. This elastic body had a tensile strength of 13 Kgf/cm 2 , an elongation of 90%, a tear strength of 9.1 Kgf/cm 2 , and an impact resilience of 50%. Comparative Example 2 30.1 parts by weight of MDI prepolymer, 64 parts by weight of 1-3 mm rubber chips (32:68), 3.4 parts by weight of iron oxide, 1.3 parts by weight of calcium carbonate, metal catalyst curing accelerator
Add 1.2 parts by weight, mix well, and add 1.2 parts by weight of this mixture.
A colored elastic pavement was obtained in the same manner as in Example 1 by applying 16.8 kg per m 2 . The tensile strength of this elastic body is 28Kgf/cm 2 , the elongation is 145%, and the tear strength is 19Kg
f/cm 2 and rebound resilience was 43%.

As a result, the elastic bodies of Examples 1 to 4 have physical properties suitable as elastic bodies for golf course walkways, and have sufficient durability for long-term use of three years or more. On the other hand, the physical properties of the elastic body of Comparative Example 1 are lower than those of the product of the present invention, and the surface of this elastic body tends to fray and crack due to continuous use, and lacks durability for long-term use. Further, in the elastic body of Comparative Example 2, a polyurethane film appeared in the form of islands on the surface of the elastic body during manufacturing, and a homogeneous elastic body was not formed. As a result, the product value is lost. In addition, in the product of the present invention, the spikes of the golf shoes enter the hollows between the elastic tips when walking, increasing the sense of stability while walking and reducing the feeling of fatigue. On the other hand, since the surface of Comparative Example 2 is covered with a hard film, it lacks the functionality of the product of the present invention. As detailed above, the colored elastic pavement of the present invention has an extremely simple composition and structure, has excellent physical properties, and is also excellent in workability and economy.
In terms of function and fashion, it is the most suitable color elastic pavement for the coming era, making it ideal for golf walking paths.
