Description
The present invention relates to a method for producing an elastic plate for artificial turf in which natural cork is mixed with talc and synthetic resin, and more specifically, 10 to 50 parts by weight of polyacetate-based synthetic resin in 100 parts by weight of cork powder particle size of 1 mm to 30 mm, 10 to 50 parts by weight of talc is mixed in a batch mixer, and then compressed into a plate having a thickness of 25mm ~ 1000mm for the artificial turf elastic plate material manufacturing method.
In addition, it is a method of manufacturing an elastic plate for artificial turf to permeate the elastic plate to the bottom of the elastic plate by drilling the Ø7mm ~ Ø10mm size in the horizontal 100mm length 100mm interval.
According to the present invention, it is possible to efficiently recycle the cork waste resources of natural cork and incinerated wood bark and to provide environmentally friendly elastic plates for artificial turf. It has the effect of blocking the pollution of the environment.
Cork is the outermost protective tissue on the stems, branches, and roots of overgrowing plants and corresponds to the bark of grown or aged trees. Over the years, the bark has been deposited with a polymer of fatty acid called sverine, which is much less than 1 in the severin deposit, making it light and difficult for water or gas to pass through. However, since the independent voids and density have excellent properties in moistureproof soundproof insulation, etc., they are used in various caps such as bottle caps, indoor wallpaper, boards, etc.
Cork is good or bad depending on the density of the physical form and the thickness of the bark, but in Korea, the production itself is insignificant, but in the process of collecting wood, many corks are produced as by-products. However, domestic cork is used for simple incineration or sawdust. However, as an elastic sheet for artificial turf to be used in the present invention utilizing the characteristics of natural, turn, fouling, deodorizing, sound absorbing, antibacterial, antifungal, far-infrared radiation, non-rotating properties, humidity control functions of the cork In case of use, there is no big difference in physical properties, so the potential value of utilization of waste and renewable resources and the efficient development of forest resources in Korea are needed.
Artificial turf is installed in places where natural grass cannot be installed or it is difficult to maintain. Natural turf has a low initial construction cost but is difficult to maintain, whereas artificial turf has a high initial cost but is easy to maintain and is widely used in school playgrounds and soccer stadiums and baseball fields.
However, since artificial turf has no softness and elasticity compared to natural grass, artificial turf is filled with recycled EPDM or waste tire powder SEBS chips to provide elasticity. However, artificial turf itself has strong frictional resistance, no moisture, and has horizontal and vertical direction due to the physical characteristics of the weaving. Therefore, serious turf and resistance occurs when the player turns and slides. In particular, long-term use of artificial turf ground can cause artificial turf surface permeation or natural ground subsidence. Therefore, it is very important to maintain the smoothness and elasticity of artificial turf playgrounds. As a result of the loss or harmful gas generated, serious environmental pollution and harmful substances are generated, so the blocking measures are very urgent.
Therefore, instead of minimizing the use of existing artificial turf rubber chips, elastic plates should be fixed to the bottom of artificial turf to maintain smoothness due to shock absorption and ground subsidence. However, currently, recycled EPDM or waste tire powder recycled vulcanized rubber powder is mixed with harmful chemical adhesives and applied to the surface, and artificial turf is laid and used. (Refer to domestic patent registration 10-780229)
These regenerative vulcanized rubber powders contain heavy metals, volatile organic chemicals, and polynuclear aromatic hydrocarbon compounds, so they smell in hot summer months and pollute soil and ground water as harmful chemicals penetrate and deteriorate the surface. Causing dermatitis. In the rain, the elastic chips are lost to sewers or streams and are not recycled or reduced.
Therefore, there is an urgent situation in which a method of manufacturing an environmentally friendly artificial grass elastic plate using natural cork, which is low in material cost and does not cause environmental problems, is urgent.
The present invention relates to a method for producing an elastic grass plate for artificial turf using a natural cork which is low in material cost and does not cause environmental problems. More specifically, the batch cork 1 mm to 30 mm granules and thermoplastic synthetic resin 30 to 50 parts by weight When the synthetic resin is deposited on the cork by mixing in a mixer, it is compressed in a molding machine to provide a method for producing an elastic plate composition for artificial turf having a specific gravity of 0.9 to 1.2 with a hardness of 10 to 80A.

It relates to a method for producing an elastic plate for use.
In the present invention, since the cork powder of about 1mm to 30mm can not be used as an elastic plate for absorbing artificial turf playground itself, a method of efficiently recycling the cork powder was put into a mixer, and the cork powder having a particle size of 1mm to 30mm was placed in a mixer. When mixed with 50 to 50 parts by weight of talc 10 to 50 parts by weight is deposited on the cork powder by the shear force, and pressurized or heated in the molding machine it can be made of an elastic plate material excellent in environmentally friendly and light resistance water resistance as a natural material.
In the present invention, 100 parts by weight of natural cork powder is added to a batch mixer, and 10 to 30 parts by weight of polyacetate-based synthetic resin is mixed with 10 to 50 parts by weight of talc. It relates to the manufacture of plate materials.
In addition, another manufacturing method as described above relates to the production of elastic plate material for artificial turf by mixing 100 to 100 parts by weight of natural cork powder emulsified synthetic resin 10 to 30 parts by weight, talc 30 parts by weight and molding with a pressure heating molding machine.
