이하에서는 본 발명에 대하여 보다 상세하게 설명하기로 한다. 그리고 하기의 설명에서는 본 발명의 EVA 폼 좌변기 시트부재를 이해하는데 필요한 부분만이 설명되며, 그 이외 부분의 설명은 본 발명의 요지를 흩트리지 않는 범위내에서 생략될 것이라는 것을 유의하여야 한다.Hereinafter, the present invention will be described in more detail. In the following description, only the parts necessary to understand the EVA foam toilet seat sheet member of the present invention will be described, it should be noted that the description of other parts will be omitted within the scope that does not disturb the gist of the present invention.
도 1은 본 발명에 따라 제작된 쿠션성이 우수한 사출 발포 일체형 EVA 폼 좌변기 시트부재의 평면도이고, 도 2는 본 발명에 따라 제작된 쿠션성이 우수한 사출 발포 일체형 EVA 폼 좌변기 시트부재의 저면도이며, 도 3은 본 발명에 따라 제작된 쿠션성이 우수한 사출 발포 일체형 EVA 폼 좌변기 시트부재를 합성수지 성형물 지지대에 고정한 결합사시도이다.1 is a plan view of an injection foamed integral EVA foam toilet seat sheet member having excellent cushioning properties manufactured according to the present invention, Figure 2 is a bottom view of an injection foamed integral EVA foam toilet seat sheet member having excellent cushionability produced according to the present invention, 3 is a combined perspective view of fixing the injection-molded one-piece EVA foam toilet seat sheet having excellent cushioning properties produced in accordance with the present invention to the synthetic resin molding support.
본 발명의 EVA 폼 좌변기 시트부재는 사출 발포하여 일체형으로 엠보가 형성된 표면이 미려한 EVA 폼 시트부재를 형성하는 제 1공정을 통해 제작된다.The EVA foam toilet seat sheet member of the present invention is manufactured through the first process of forming an EVA foam sheet member having a beautiful surface embossed by injection foam.
즉, 본 발명에 따른 EVA 폼 좌변기 시트부재는 EVA를 사출 발포하여 제조되며, 힌지부가 형성된 합성수지 성형물 지지대에 고정되어 변기시트를 형성하는 것으로, 종래의 좌변기용 시트부재에 비하여 쿠션감이 양호할 뿐만 아니라, 엠보가 형성되어 통기가 양호하며, EVA 재질로 제작되어 PVC 및 폴리우레탄 재질로 된 것에 비하여 내구성이 우수한 효과가 있다.That is, the EVA foam toilet seat sheet member according to the present invention is manufactured by injection molding the EVA, and is fixed to the synthetic resin molded support formed by the hinge portion to form a toilet seat, a cushioning feeling is better than the conventional toilet seat member. Rather, the emboss is formed, good ventilation, and is made of EVA material has excellent durability compared to made of PVC and polyurethane material.
상기 엠보는 지름 10~30mm를 갖는 것이 바람직하다. 상기 엠보의 지름이 10mm 미만이면 통기 성능은 우수하나 사용자가 이물감을 느끼게 되어 사용하기에 부적절하고, 30mm를 초과하면 통기 효과가 미미하다.The embossing preferably has a diameter of 10 to 30 mm. If the diameter of the embossing is less than 10mm, the ventilation performance is excellent, but the user feels a foreign object, and is not suitable for use, and if it exceeds 30mm, the ventilation effect is insignificant.
한편, 본 발명의 EVA 폼은 EVA 수지와 통상적인 폼 배합용 가교제, 발포제 및 첨가제를 혼합하여 제조한다.Meanwhile, the EVA foam of the present invention is prepared by mixing an EVA resin and a conventional foam compounding crosslinking agent, foaming agent and additives.
본 발명에서 사용하는 EVA 수지는 바람직하게는 Vinyl Acetate(VA) 함량이 15내지 30중량%의 범위를 갖는 것이 바람직하다. 상기 VA 함량이 15% 미만이면, EVA 폼의 탄성이 적게 되어 쿠션성이 감소하고, 30%를 초과하면, 발포가 어려우며, 점착성이 증가하여 사용자가 불쾌감을 느끼게 될 우려가 있다.EVA resin used in the present invention preferably has a vinyl acetate (VA) content of 15 to 30% by weight. If the VA content is less than 15%, the elasticity of the EVA foam is reduced, the cushioning property is reduced, if it exceeds 30%, foaming is difficult, the adhesiveness increases, there is a fear that the user may feel uncomfortable.
또한, 상기의 사출 발포하여 제조되는 EVA 폼은 발포배율이 200~250%의 범위를 갖는 것이 바람직하다. 상기 발포배율이 200% 미만이면, 경도가 증가하여 장시간 사용시 불편함을 느끼게 되고, 250%를 초과하면 경도가 감소하여 쿠션성이 감소하게 된다.In addition, the EVA foam produced by the injection molding of the foaming ratio is preferably in the range of 200 ~ 250%. If the expansion ratio is less than 200%, the hardness is increased to feel uncomfortable when using for a long time, if it exceeds 250% the hardness is reduced to decrease the cushioning properties.
