Description

Elastic flooring materials for sports facilities

The present invention relates to an elastic packaging material containing various stone powders and polyurethanes, and more specifically, to mix 20 to 60% by weight of general stone powders and 40 to 80% by weight of polyurethane, in order to impart functionality in some cases. Instead of ordinary stone powder, add 20 ~ 60% by weight of elvan, natural jade, serpentine, kaolin, ceramic, illite, germanium, ocher, charcoal or carbon powder with far-infrared radiation function and anion generating effect. It relates to an elastic flooring material for athletic facilities that can be molded by.

Conventional road surface is mainly formed by cement pavement or asphalt pavement, using cement block or by compacting the road itself, but when using cement or asphalt pavement or cement block, there is no buffering effect, so jogging or other Rather than impairing the joints and the health during exercise, there are problems such as deformation or damage due to the passage of the vehicle and frequent replacement.In the case of road compaction with dirt, the road structure is fragile due to rain or vehicle passing. It is easy to settle down or deform, and frequent maintenance is required, and when the dust is generated during drying and the water is not quickly discharged during rainfall, the road surface flutters and dirt sticks when walking.

In order to solve this problem, Utility Model Registration No. 190054 describes a pavement road using waste tires. However, there is an advantage in recycling waste tires, which are wastes. Waste tire powder falls off from the road surface, and there is no color and physical properties such as shock absorbency, durability, cold resistance, elastic resilience, and softness are inferior to the body when walking or running, and fatigue occurs easily. There are limitations in obtaining the effect of natural road surface, and in order to manufacture waste tire powder, tire cord must be separated from waste tire and desulfurization process is required, which makes the process of obtaining main material complicated and expensive. there was.

On the other hand, polyurethane foam (trade name: Styrofoam) is widely used as insulation and sound absorbing material in building materials, but it is weak to heat, not easy to handle, and plays an important role in spreading fire in case of fire. It is a required situation.
In addition, as is widely known, polyurethane is formed by combining polyol and isocyanate with other additives, and since the reaction occurs quickly when the polyol and isocyanate are combined, it is expensive to add additives such as stone powder. Since only polyurethane is used, there is a problem of costly construction of elastic packaging and the like.

Accordingly, an object of the present invention is to solve the problem of causing environmental pollution, and to provide an elastic flooring material for athletic facilities that is not only possible to replace the currently available road pavement, insulation, sound absorbing material at a low price.

In order to achieve not only the above-mentioned object but also other objects that are easily expressed, in the present invention, 20 to 60% by weight of general stone powder and 40 to 80% by weight of polyurethane are mixed, but in order to give functionality, general stone powder Instead, add 20 to 60% by weight of ganban stone, natural jade, serpentine, kaolin, ceramic, elite, germanium, ocher, charcoal, and carbon powder, which have far-infrared radiation function and anion generating effect, and mix and shape The manufacture of functional materials solves the problem of causing environmental pollution, and it can be recycled by melt method even at the end of its service life with low price. Could get.

The present invention is described in more detail as follows.

Elastic flooring material for athletic facilities according to the present invention is mixed with 20 to 60% by weight of general stone powder and 40 to 80% by weight of polyurethane, but in order to give functionality in the case of far-infrared radiation function and anion generation effect in place of general stone powder 20 to 60% by weight of ganban stone, natural jade, serpentine, kaolin, ceramic, illite, germanium, ocher, charcoal or carbon powder are added to the stone powder and mixed (mixed) uniformly and packed on the floor of a sports facility, etc. It can be formed into a shape.

The use of the elastic flooring according to the present invention can be used as a paving block for sidewalks, elastic flooring, land tracks, playgrounds, roller skates, sound absorption for building materials, insulation, etc., and directly mixed in the field without molding to a specific shape It can also be used as a packaging material.

In the present invention, by using the stone powder as the main material can not only have almost the same physical properties as the natural road surface, there is no fear of causing environmental pollution by not using waste tires, and since it is a material that can be easily obtained anywhere, the production cost is very low It works.

Since the stone powder has a rough surface, even if a small amount of polyurethane is used, it is easy to be molded or processed as a product according to the use of the product of the present invention, and the amount of polyurethane is used is excellent in heat resistance, and sound absorption and insulation due to the fine pore of the stone powder The effect can also be obtained an excellent effect. When the amount of the stone used is more than 60% by weight or the amount of the polyurethane used exceeds 40% by weight, the effect of using the stone is reduced, and there is a disadvantage in that molding of the product with a specific shape is not easy.

In the present invention, at least one selected from the group consisting of ganban stone, natural jade, serpentine, kaolin, ceramic, illite, germanium, loess, charcoal and carbon powder having far-infrared radiation function and anion generating effect instead of the general stone powder Various functions can be imposed by using 20-60 weight% of the above. In this case, when the amount of at least one or more selected from the group consisting of ganbanite, natural jade, serpentine, kaolin, ceramic, elite, germanium, loess, charcoal, and carbon powder having far-infrared radiation function and anion generating effect is less than 20% by weight If the degree of expression of the functionality is weak and exceeds 60% by weight, it will cause a rise in product prices.

Illite and elvan are known materials that emit inorganic germanium, far infrared rays and the like that are beneficial to the human body. The illite is a clay soft mica mineral, and has a unique property with silkiness when solved in water as a three-layered scale-like structure, and is composed of yellowish-white synthetic material composed of main components SiO ₂ , Al ₂ O ₃ , K ₂ O, FeO _2, etc. It is a mineral, and its physicochemical property is effective in dissipating a large amount of dissolved oxygen in water, and it has good adsorption ability to adsorb heavy metal ions, organic ions, and depleted organic odors, which are dissolved in water. It can be used as a raw material for toxic gas and odor remover.

In addition, illite contains more than 150ppm of inorganic germanium, which has the effect of promoting the metabolism of the human body. As a result of the toxic gas adsorption and desorption test of the illite, C0 was removed 15% under the condition of flow rate 10ml / min, adsorbed CO was started to desorption at a temperature of 280 ℃, H ₂ O flow rate 10ml 100% was removed under the condition of / min, and the desorption of adsorbed H ₂ S was predicted. The results of far-infrared spectroscopy showed that the far-infrared radiation of 3 ~ 14㎛ wavelength was 82.98% at the measurement temperature of 229 ℃ It is revealed that the far infrared radiation efficacy is also excellent in Patent No. 303911.

Elvan, as is well known, is a mineral mainly composed of SiO ₂ , Al ₂ O ₃ , Fe ₂ O ₃ , CaO, MgO, K ₂ O, Na ₂ O, TiO ₂ , MnO, P ₂ O ₅ . In particular, because it is a porous inorganic material, it is known as having an excellent antibacterial and neutralizing properties.

Natural jade and serpentine are dense and hard, and are rich in components such as magnesium, iron, silicon, calcium, copper, and zinc, which are the source of human energy. It emits infrared rays continuously to help the user to concentrate and sleep and to activate the immune function.

Kaolin used in the present invention is the most commonly used material among porcelain raw materials, and is a clay that is abundant in the ancient provinces of China. The British people first named Koline after the name and named Kaoline. Kaolin's chemical formula is Al ₂ O ₃ + SiO ₂ + 2H ₂ O, which is composed of clay, quartz, and decomposed feldspar. In Korea, high-quality kaolin is collected from Hadong, Sancheong, and Seongju. Kaolins produced in the United States, Florida, Carolina, and Georgia are called Ball Kaoline, Ball Clay, or EPK Edgar Plastic Kaoline, among which the clay is the most plastic kaolin.

Ocher is scattered throughout the country. Although it varies slightly from region to region, it is a clay material belonging to mesophilic clay (approximately 1,000 ~ 1,200 or so) containing iron.

In general, charcoal refers to the change of carbonized material into carbonized material as the microcellular tissue is carbonized in the process of burning wood at 400 to 1300 ℃, and numerous pores are formed on the surface. It is widely used to have the effect of anti-oxidation, far-infrared radiation, anion divergence, humidity control, electromagnetic shielding.
