놀이터용 완충 및 배수 고무매트{Playground Cushion and Draining Rubber Mat}Playground Cushion and Draining Rubber Mat}

본 발명은 놀이터용 완충 및 배수 고무매트에 관한 것으로, 더욱 상세하게는 고무칩, 우레탄바인더 및 고체형 우레탄바인더를 성형하여 제조되되, 고체형태 바인더를 이용하여 고열에서 액체가 액상으로 변하여 공극이 발생되도록 함과 동시에 바인더 역할을 하도록 제조된 것으로서, 놀이터에서 충격을 흡수하는 완충기능을 수행하며 동시에 높은 투수성으로 저면에 형성된 배수로를 통해 배수가 가능하도록 된 새로운 형태의 놀이터용 완충 및 배수 고무매트에 관한 것이다.
The present invention relates to a buffer and drainage rubber mat for playgrounds. More specifically, the rubber chips, urethane binders and solid urethane binders are manufactured by molding the liquid into a liquid phase at a high temperature using a solid binder to generate voids. It is manufactured to act as a binder and at the same time, a shock absorbing function in the playground to absorb shocks and at the same time a high permeability to a new type of playground buffer and drainage rubber mats to enable drainage through the drainage formed on the bottom It is about.

종래에 체육 근린시설 및 놀이터 등의 바닥에 시공되는 탄성포장재의 시공으로는 물빠짐과 탄성은 좋으나 인장강도 신장율과 경도 등이 떨어져 수명이 짧고, 고무매트는 인장강도 신장율과 경도 등은 좋으나, 투수성 및 탄성이 부족하였다.Conventionally, the elastic packing material which is installed on the floor of sports facilities and playgrounds has good water drainage and elasticity, but the tensile strength elongation rate and hardness are short, so the life span is short, and the rubber mat has good tensile strength elongation rate and hardness, Lack of elasticity and elasticity.

또한 모래 바닥의 경우 기생충등 위생문제와 유실이 문제시 되었다. In the case of the sandy bottom, hygiene problems such as parasites and loss have been a problem.

또한, 종래에 인도, 체육근린시설 및 놀이터 등의 바닥에 시공되는 바닥아스콘의 시공으로는 물빠짐이나 인장강도, 신장율과 경도 등이 적정규정치에 적절하게 맞추어지지 않았고, 또한 경우에 따라서는 콘크리트나 아스팔트피치등의 소재로 시공되는 것이 대다수 였었다.In addition, in the conventional construction of flooring asphalt concrete on the floor of sidewalks, sports facilities, and playgrounds, water drainage, tensile strength, elongation rate and hardness have not been properly adjusted to the appropriate standard values. Most of them were constructed with materials such as asphalt pitch.

콘크리트 소재는 경도 및 내열성등이 우수하여 나름대로 유용하게 사용되고 있으나, 경도가 우수한 반면 충격을 잘 흡수하지 못하여 체육근린시설, 놀이터 등을 이용하는 사용자가 상기 시설들을 이용하는 도중에 부상을 당하기 쉬운 문제점이 있다.The concrete material has excellent hardness and heat resistance, but is usefully used in its own way. However, since the hardness is excellent, it does not absorb shock well, so that a user using a sports neighborhood facility, a playground, etc. is easily injured while using the facilities.

이러한 문제점을 해결하기 위하여 개시된 하단부 돌출형 매트(대한민국 실용신안등록번호 제20-0389089호, 2005년06월29일 등록)는, 사각형상으로 구성된 폐타이어를 재활용한 고무매트의 하단 표면에 사다리꼴 형상의 요철을 형성시켜서 공원, 놀이터, 도로변의 인도 등에 설치하여 사용자의 신체에 가해지는 충격을분산시키는 것으로, 폐타이어를 이용한 하단부 돌출형 고무매트에 있어서, 상기 고무매트는 폐타이어분말 80 내지 90 중량% 와 폴리우레탄결합체 5 내지 10 중량 % 및 염료 5 내지 10 중량% 로 이루어진 상부판 (10); 및 폐타이어분말 90 내지 98 중량% 와 폴리우레탄 결합체 2 내지 10 중량% 로 이루어진 하부판 (20)로 구성되고, 상기 하부판(20)은 다수의 요철부가 상기 상부판의 밑면부의 전체면에 바둑판 모양으로 형성되고, 상기 각각의 요철은 서로가 20 내지 25 mm 의 간격을 가지도록 형성되고, 상기 폐타이어분말의 각각의 직경이 3 내지 6 mm 이고, 상기 하단부돌출형 고무매트의 상부판과 하부판은 금형에 투입되어 150 내지 190 도의 온도하에서 제조되고, 상기 하단부 돌출형 고무매트의 하단부 (20) 의 각 요철의 높이가 10 내지 30 mm 인 것을 특징으로 하여 폐타이어를 이용하는 환경친화적인 제품으로서 공정의 신속성과 인건비의 절감등의 효과가 있고, 적절한 탄성을 유지하여 충격흡수력이 우수하고, 내구성 및 내마모성이 우수하고 경제적이며 어린이들의 안전한 사용이 가능한 것이다.In order to solve this problem, the lower protruded mat (Korean Utility Model Registration No. 20-0389089, registered on June 29, 2005) has a trapezoidal shape on the lower surface of the rubber mat in which a waste tire composed of a rectangular shape is recycled. By forming the irregularities of the installation in a park, a playground, a roadside, etc. to distribute the impact applied to the user's body, the rubber mat in the bottom portion protruding rubber mat using waste tires, the rubber tire 80 to 90 weight A top plate 10 composed of 5 to 10 wt% of polyurethane binder and 5 to 10 wt% of dye; And a lower plate 20 composed of 90 to 98% by weight of waste tire powder and 2 to 10% by weight of polyurethane binder, wherein the lower plate 20 has a plurality of irregularities in a checkerboard shape on the entire surface of the bottom of the upper plate. The convex and convex portions are formed to have an interval of 20 to 25 mm from each other, and each of the waste tire powders has a diameter of 3 to 6 mm, and the upper plate and the lower plate of the lower protrusion type rubber mat are formed of a mold. It is put under the temperature of 150 to 190 degrees, and the height of each unevenness of the lower end portion 20 of the lower end protruding rubber mat is characterized in that the height of 10 to 30 mm, the speed of the process as an environmentally friendly product using waste tires It has the effect of reducing labor costs and labor costs, and maintains the proper elasticity to provide excellent shock absorption, durability and wear resistance, economical and safe children. This will be possible.

그러나 상기 종래기술은 상부판 및 하부판이 모두 충진된 재료로 이루어져 충격흡수력과 투수성이 좋지 못한 문제점이 있었다. 또한 충진된 재료로 이루어져 외부에서 충격이 가해질 때 고무매트의 일부가 파손되기 쉬운 문제점이 있었다.
However, the prior art has a problem that the shock absorbing power and the water permeability are poor because the upper plate and the lower plate are both filled with the material. In addition, there is a problem that a portion of the rubber mat is easily broken when the impact is applied from the outside made of a filled material.

도 2를 참조하면, 놀이터용 완충 및 배수 고무매트는 성형프레스(미도시)라는 장치에 의해 제조되는데, 그 과정을 간단히 설명한다.Referring to Figure 2, the playground buffer and drainage rubber mat is manufactured by a device called a molding press (not shown), the process will be briefly described.

먼저 놀이터용 완충 및 배수 고무매트에 있어서, First, in the buffer and drainage rubber mats for playgrounds,

고무칩(고무분말) 75 내지 90 중량%와 우레탄바인더 5 내지 15 중량 % 및 안료 5 내지 15 중량% 로 이루어진 제2층; 및A second layer comprising 75 to 90 wt% of rubber chips (rubber powder), 5 to 15 wt% of urethane binder, and 5 to 15 wt% of pigment; And

고무칩(고무분말) 75 내지 90 중량%와 우레탄바인더 5 내지 10 중량 % 및 고체형 우레탄 바인더 5 내지 15 중량% 로 이루어진 제1층;을 고무매트 성형 프레스에 준비한다(S2).A first layer consisting of 75 to 90% by weight of rubber chips (rubber powder), 5 to 10% by weight of urethane binder, and 5 to 15% by weight of solid urethane binder; is prepared in a rubber mat molding press (S2).

이후, 고무매트성형 프레스를 사용하여 성형하되(S4),Then, molding using a rubber mat molding press (S4),

상면은 평평하고 저면에는 복수개의 돌출부가 형성되며, 상기 복수개의 돌출부로 인해 돌출부들 사이에 배수로가 형성된 것을 특징으로 한다.The upper surface is flat and a plurality of protrusions are formed on the bottom, and a plurality of protrusions are formed between the protrusions due to the plurality of protrusions.

상기 성형프레스에서의 성형 온도는 섭씨 135 내지 210도이고 성형시간은 10 내지 26분인 것을 특징으로 한다.
The molding temperature in the molding press is 135 to 210 degrees Celsius and the molding time is characterized in that 10 to 26 minutes.

상기 단계 S4에서, 성형과정에서 고체형태의 바인더를 이용하여 고무칩과 혼합하여 성형하게 되는데, 상기 고체형태의 바인더는 고열에서 고체가 액상으로 변하는 공극 발생과 동시에 바인더 역할을 하게 된다.In the step S4, the molding process is performed by mixing with a rubber chip using a solid binder, and the solid binder serves as a binder simultaneously with the generation of voids in which the solid turns into a liquid at high heat.

이때, 공극은 매트 하부판 전체적으로 발생 된다. 상기 과정에서, 고체 바인더는 고무분말과 같이 배합되어 균일하게 투입 되며, 투입 후 일정시간이 지나 열이 충분히 가해졌을 때 용해되며 일부 스티로폼과 같은 형상을 띈다.
At this time, the voids are generated throughout the mat bottom plate. In the above process, the solid binder is mixed with the rubber powder and uniformly added thereto, and after a certain time after the addition, the solid binder dissolves and forms some styrofoam-like shape.

도 3 및 도 4를 참조하면, 3 and 4,

본 발명에 따른 놀이터용 충격 및 배수 고무매트(100)에 있어서, 고무매트(100)의 측단면 중간 중간에 다수개의 공극(110a)이 형성된 것을 볼 수 있다. 이들 복수개의 공극(110a)은 성형과정에서 고체형태의 바인더가 고온에서 용융되어 생긴 공간이다.In the impact and drainage rubber mat 100 for a playground according to the present invention, it can be seen that a plurality of voids 110a are formed in the middle of the side cross section of the rubber mat 100. The plurality of voids 110a are spaces formed by melting a solid binder at a high temperature during molding.

미설명부호 122 및 124는 배수로를 나타낸다. 이는 돌출부(120)를 성형하는과정에서 함께 형성된 것이다.Reference numerals 122 and 124 denote drainage channels. This is formed together in the process of forming the protrusion 120.
