Description

Elastic flooring for sports facilities {Resilient Sports Flooring}

The present invention relates to elastic flooring for sports facilities. More specifically, the present invention relates to an elastic flooring material for a sports mat of a molded mat type having a layer structure consisting of a tread layer of an upper layer and a support formation of a lower layer.

In general, the elastic flooring material adjusts the landing impact during driving or walking to increase the shock absorbing characteristics when the foot lands on the ground, thereby reducing the burden on the body and ensuring safety, and the floor repulsion force caused by the reaction of body acceleration after landing. The damping degree is lowered so as to improve the movement characteristics necessary for running and walking.

Such elastic flooring is widely used as a shock absorbing flooring material for athletic tracks, basketball courts, volleyball courts, tennis courts, jogging tracks, bicycle paths, walkways, playgrounds, etc. Various types of elastic flooring materials are used, such as elastic epoxy flooring and polyvinyl chloride (PVC) flooring.

Among these, elastic flooring materials widely used in sports facilities such as athletic tracks such as running tracks, basketball courts, and volleyball courts include polyurethane (Polyurethan, PU) chips, EPDM (Ethylene Propylene Diene Terpolymer) chips, or recycled rubber chips. The elastic rubber flooring material to be used is widely known.

The rubber flooring material using the rubber chip is a rubber chip elastic flooring material of a construction method for laying rubber chips, and a mat type of a method in which a rubber chip is pressed and molded into a mat or block of a desired size and color. It is roughly classified as elastic flooring.

The rubber chips used in the elastic flooring materials include polyurethane chips, EPDM chips, and recycled rubber chips as described above. The characteristics of the rubber chips will be described below.

Polyurethane is formed by binding of molecules while alcohol and isocyanate generate heat of reaction by polymerization. Polyurethane chips have good affinity with polyurethane binders for excellent adhesive strength and excellent abrasion resistance due to the characteristics of polyurethane materials. In particular, polyurethane chips have excellent weather resistance and chemical resistance, so they can be easily changed even when exposed to UV rays or acid rain. It is characterized by little change in physical properties.

EPDM is a synthetic rubber composed of ethylene, propylene, and non-conjugated diene. It has excellent ozone resistance, cold resistance, heat resistance, solvent resistance, color stability, and various colors. It is widely used as an elastic flooring material.

There are various kinds of recycled rubbers such as waste tires and automobile parts. Since recycled rubbers are black in color, they can produce various surfaces as polyurethane resins and coatings on the surface after chip construction, so tennis courts, outdoor basketball courts, children's playgrounds, parks It is widely used as a flooring material for walkways and disabled facilities. In addition, recycled rubber is an eco-friendly product that recycles industrial waste rubber and uses it as an excellent high-elastic floor packaging material.

Referring to the manufacturing process of the rubber chip used as the elastic rubber flooring using a polyurethane, EPDM or recycled rubber having such characteristics as follows.

Rubber chips are pulverized using a cutter mill to have a range of particle sizes such as polyurethane, EPDM, or recycled rubber. The crushed rubber chip is configured to have an even particle size distribution to improve the elasticity according to the porosity and the adhesiveness with the binder when stirring. It is preferable to use a urethane-based binder having good elasticity and adhesiveness as a binder, and the rubber chip and the binder are mixed using a stirrer, but the rubber chip is first mixed and then the binder is uniformly added. It is preferable to mix.

Using the elastic rubber flooring material using the rubber chip produced by the above-described process, the method of constructing a shock absorbing flooring material of sports facilities such as a running track or multi-purpose outdoor stadium, the mat-shaped flooring of the pressure-molded form of the rubber chip It can be largely divided into a method of use and a method of laying rubber chips at a construction site.

The mat floor is filled with rubber chips mixed at an appropriate mixing ratio into a mold, and then pressed under a predetermined temperature at a predetermined temperature while applying pressure to form a mat or block having a desired size and color. Press-molded mat-shaped elastic flooring is applied either directly to the track of an athletic field or indoor gymnasium, and to a field of a general athletic field, or to a track or a stadium floor and the bottom of a field surface which are separately constructed. The thickness, elasticity, strength, and the like can be appropriately changed and molded according to the use and properties.

In the related art, U.S. Patent No. 4042888, Italian Patent No. 1082914, Japanese Patent Application No. 47-19358, and Japanese Patent Application No. 61-176760 combine the crushed rubber chips with a binder and then press There is a technique of forming a sheet by processing and molding, or attaching it flat to a certain thickness on a nonwoven fabric or an impregnated paper.

Next, the construction method of the elastic flooring of the method of laying the rubber chip in detail as follows.

The installation method of laying rubber chips is a step of treating the floor to be constructed with elastic floor, applying a primer, laying a step of elastic flooring, and sealing step, which is a finishing process of chip pores. , Liquid urethane coating step, top coating step, line marking step, and curing step.

Underfloor treatment is to clean and dry the floor surface on which the elastic flooring material is to be laid, and then to dry out, find the recessed part of the floor surface, and then patch the recessed part with the elastic flooring and then dry it. It finds a weak part on the floor surface of concrete and ASCON (asphalt concrete) and performs the reinforcement work of the base material by applying a thin layer of epoxy to facilitate the adhesion and application of the binder afterwards.

After the bottom treatment step, a primer is applied to apply a thin layer of binder to the concrete surface using a roller or a spray. This is to make the surface condition uniform and even.

An elastic floor laying step is followed by laying down the elastic flooring material before the binder applied in the primer application step is cured. The installation of the elastic flooring material before the binder is cured is to enhance the adhesiveness between the elastic flooring material and the concrete.

The elastic floor laying step is to install the rubber chip and binder directly at the construction site by using a finisher (Rubber Paver) or a hand tool within a predetermined time.The binder hardens after a long time after mixing. In consideration of the curing time of, the preparation should be carried out immediately after completion of the formulation.

Then, the constant temperature roller is repeatedly moved to the laying surface of the elastic flooring material many times, and the surface is repeatedly compressed to form a flat surface while applying a constant pressure. The parts not in contact with the constant temperature roller and the defective parts are pressurized using a thermal iron.

The elastic layer completed by the above-described process is cured by curing (curing) for at least 24 hours or more, and then proceeds to the next step, the sealing step.

Sealing (Sealing) step is to put the sealing material in the air hole generated during the curing of the elastic flooring material to finish the gap to prevent the cracks by filling the voids between the rubber chip particles. When the sealing material is cured, the liquid urethane coating step is performed.

Liquid urethane coating step is to apply a liquid urethane for the waterproofing of the floor to be carried out over a second, and after the applied liquid urethane is sufficiently cured to perform the next step. Liquid urethane is also excellent in elasticity, so also has the effect of improving the elasticity of the construction floor.

Up to the liquid urethane coating step, the top coating step of coating the color by mixing the urethane resin and the pigment on the rough construction surface. Rubber chips made of polyurethane, EPDM, or recycled rubber are used as the elastic flooring material. Since the color is mainly black, the appearance is not good and the floors cannot be expressed in various colors. Top coated with the desired color. After the construction, the pigment used in the top coating and the urethane resin are sufficiently cured.

In the line marking step, the marking is performed on the ground surface of the constructed floor according to the purpose of construction, and the marking line or the pattern is marked for each use purpose such as a running track, a basketball court, a foot ball court, a tennis court, a bicycle road, and a pedestrian road. .

Finally, access to the construction site is controlled and there is a curing phase for more than two days.

The multi-purpose stadiums such as running tracks, basketball courts, foot volleyball courts, tennis courts, and shock absorbing elastic floors such as bicycle paths and pedestrian tracks can be applied to the installation surface of the elastic flooring material and liquid urethane coating. By doing so, durability and elasticity are improved.

However, in general, when the elastic rubber flooring using the conventional rubber chip is installed as a shock absorbing flooring of sports facilities such as a running track or a multipurpose outdoor stadium, the following problems exist.

The elastic flooring material using the conventional polyurethane (PU) chip contains heavy metals such as mercury, a pollutant harmful to the human body, and is easily damaged due to corrosion and aging of the upper layer, and is repaired when repairing damaged parts. The physical properties of the part has a problem that is different from the existing part.

In particular, the method of laying rubber chips at the construction site is difficult to control uniform quality such as elasticity varies depending on thickness, humidity, curing temperature, and the number of constructions. It does not meet demanding standards, and it poses a problem that samples and construction products do not have the same performance.

In addition, in order to provide the best athletic performance in various kinds of sports, an elastic flooring material having excellent resilience and shock absorbing power is required, and the elastic flooring material using rubber chips has a difficult problem in meeting these demands.

Accordingly, there is a need for an elastic flooring material for sports facilities that does not contain heavy metal substances that are harmful to the human body, is easy to control quality such as excellent durability and uniform elasticity, and provides the best performance to athletes with excellent resilience and shock absorption. It is true.
