본 발명은 바닥재를 구성하는 중간층 시공용 수지조성물에 관한 것으로서, 특히 바닥재 시공시 접착제층 상부에 여러겹으로 도포되어 중간층을 이루게되는 수지조성물에 관한 것이다.The present invention relates to a resin composition for the construction of the intermediate layer constituting the flooring, and more particularly to a resin composition to form an intermediate layer by applying a plurality of layers on the adhesive layer during construction of the flooring.

종래의 바닥재는 도 1 에 도시된 바와같이Conventional flooring is shown in Figure 1

골재층(8)의 상부에 아스콘 또는 콘크리트를 일정두께로 도포한 후 가압처리하여 바닥층(7)을 형성하고, 상기 바닥층(7)의 상부에 하도전용 접착제를 도포하여 접착제층(6)을 형성하며, 상기 접착제층(6)의 상부에는 폴리우레탄 수지를 주재료로하는 중간층(5)을 형성하고, 상기 중간층(5)의 상부에 폴리우레아(Poly Urea)를 주재료로 하는 표면층(4)을 형성하여 구성된다.Ascon or concrete is applied to the top of the aggregate layer 8 to a predetermined thickness, and then pressurized to form a bottom layer 7, and an adhesive layer 6 is formed on the top of the bottom layer 7 to form an adhesive layer 6. The intermediate layer 5 mainly composed of polyurethane resin is formed on the adhesive layer 6, and the surface layer 4 mainly formed of polyurea is formed on the intermediate layer 5. It is configured by.

상기 중간층(5)은 접착제층(6) 상부에 폴리우레탄 수지를 여러겹으로 적층 도포하여 이룬다.The intermediate layer 5 is formed by laminating and applying several layers of polyurethane resin on the adhesive layer 6.

이러한 바닥재는 현재 실내 주차장 바닥, 인라인스케이트 트랙, 농구코트 등에 널리 사용되고 있다.Such flooring is currently widely used in indoor parking lot floors, inline skate tracks, basketball courts, and the like.

그러나, 종래기술은 중간층을 단순히 폴리우레탄 수지를 여러겹 적층 도포하여 구성하는 것이기 때문에 중간층 자체의 인장강도가 약하고, 중간층 아래의 접착제층과 결합강도 및 상부의 표면층과의 결합강도가 약하여 바닥재 표면이 쉽게 중간층으로부터 벗겨지는 문제점이 발생하고 있었다.However, in the prior art, since the intermediate layer is simply formed by applying a plurality of layers of polyurethane resin, the tensile strength of the intermediate layer itself is weak, and the adhesive layer and the bonding strength of the intermediate layer and the bonding strength of the upper surface layer are weak. There was a problem of peeling easily from the intermediate layer.

상기 문제점을 해결하기 위한 본 발명은 에폭시 수지 또는 우레탄수지 또는 아크릴수지 중 어느 하나의 수지로서 이루어진 수지원액에 총 100중량% 대비 0.5~1중량%의 첨가재를 혼합하되, 상기 첨가재는 PP(Poly Propylene), PVA(Polyvinyl accetate), 나일론 중 어느 하나의 소재로 이루어진 3~10mm 길이의 극세사 양끝단에 다수의 분할 보강사를 분기시켜 구성한 것을 특징으로 한다.The present invention for solving the above problems is mixed with an additive of 0.5 to 1% by weight compared to a total of 100% by weight of the resin support solution made of any one of an epoxy resin or a urethane resin or acrylic resin, the additive is PP (Poly Propylene) ), PVA (Polyvinyl accetate), nylon is characterized by consisting of a plurality of split reinforcement branches on both ends of the microfiber length of 3 ~ 10mm length of any one material.

본 발명에 의하면, According to the invention,

바닥재 시공시 중간층을 이루는 수지에 분할 보강사가 양끝단에 구비된 극세사가 첨가되므로 중간층의 인장강도가 보강됨은 물론 상측 표면층과의 결합강도가 향상되어 전체적인 바닥재의 결합강도를 향상시키는 효과를 기대할 수 있다.Since the microfiber yarns with split reinforcement yarns at both ends are added to the resin that forms the intermediate layer during the construction of the flooring material, the tensile strength of the intermediate layer is reinforced, and the bonding strength with the upper surface layer is improved, so that the overall bond strength of the flooring material can be expected. .

이하, 첨부된 도면 도 2 내지 도 5 를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 2 to 5.

본 발명의 설명에 있어서 종래와 동일한 구성요소에 대해서는 동일부호 표기하여 중복설명을 피하기로 한다.In the description of the present invention, the same components as in the prior art will be denoted by the same reference numerals to avoid redundant description.

상기 구성과 같이 본 발명의 수지 조성물은 우레탄 수지 또는 아크릴 수지 또는 에폭시 수지 중 어느 하나의 수지(10) 원액에 전체 100중량% 대비 0.5~1중량%의 첨가재를 혼합한 것이다.As described above, the resin composition of the present invention is a mixture of 0.5 to 1% by weight of the additive of any one of the resin 10 stock solution of the urethane resin, acrylic resin or epoxy resin.

상기 첨가재(11)는 도 2 에 도시된 바와같이 PP(Poly Propylene), PVA(Polyvinyl accetate), 나일론 중 어느 하나의 소재로 이루어진 3~10mm 길이의 극세사(100)를 구비하고, 상기 극세사(100)의 양끝단에 다수의 분할 보강사(101)를 분기시켜 구성한다.As shown in FIG. 2, the additive 11 includes a microfiber 100 having a length of 3 to 10 mm made of any one material of polypropylene (PP), polyvinyl accetate (PVA), and nylon, and the microfiber 100 A plurality of split reinforcement yarns (101) are branched at both ends of the c).

상기 극세사(100)는 중간층(5) 형성시 수지(10)의 사이사이에 존재하면서 수 지(10)의 결합력을 증대시켜 전체적인 중간층(5)의 인장강도가 향상되도록 하며, 또한 상기 극세사(100)의 양끝단에 분기되어 있는 다수의 분할 보강사(101)는 넓게 퍼진 상태로 고형화되므로 중간층(5)의 인장강도를 한층 더 향상시키는 기능을 제공하게 된다.The microfiber 100 is present between the resin 10 when the intermediate layer 5 is formed to increase the bonding strength of the resin 10 to improve the tensile strength of the overall intermediate layer 5, and also the microfiber 100 Since the plurality of split reinforcing yarns (101) branched at both ends of the solidification is solidified in a wide spread state, it provides a function of further improving the tensile strength of the intermediate layer (5).

본 발명의 수지 조성물 제조과정을 설명하면,Referring to the manufacturing process of the resin composition of the present invention,

준비된 수지(10) 원액과 첨가재(11)를 교반기에 투입하여 약 1시간 교반시키는데, 상기 첨가재(11)의 투입량은 전체 수지 조성물이 100중량%라 할때 약 0.5~1중량%의 첨가재(11)를 투입하는 것이 바람직하다.The prepared resin 10 stock solution and the additive 11 were added to a stirrer and stirred for about 1 hour. The amount of the additive 11 was about 0.5 to 1 wt% of the additive when the total resin composition was 100 wt% (11). It is preferable to add).

수지(10) 원액에 첨가재(11)를 넣고 1시간 교반시키면 도 3 에 도시된 바와같이 수지(10) 원액에 첨가재(11)가 골고루 퍼진상태로 혼합되어 본 발명의 수지 조성물을 완성하게된다.When the additive 11 is added to the stock solution of resin 10 and stirred for 1 hour, the additive 11 is evenly mixed in the stock solution of resin 10 to complete the resin composition of the present invention as shown in FIG. 3.

상기 완성된 수지 조성물은 별도의 밀폐용기에 투입하여 소비자에게 제공한다.The completed resin composition is put into a separate sealed container to provide to the consumer.

상기 제조된 본 발명의 수지 조성물은 수지(10)의 비중에 비해 첨가재(11)의 무게가 워낙 가볍기 때문에 수지 조성물을 용기에 담아 출하하여 장시간 방치하더라도 첨가재(11)가 가라앉지 않고 초기 혼합된 상태를 그대로 유지하게 된다.Since the resin composition of the present invention is lighter than the specific gravity of the resin 10, the weight of the additive 11 is so light that even if the resin composition is shipped in a container and left for a long time, the additive 11 does not sink and is initially mixed. Will remain the same.

여기서, 본 발명의 수지 조성물을 이용하여 중간층(5)을 시공하는 과정을 설명하면 다음과 같다.Here, the process of constructing the intermediate layer 5 using the resin composition of the present invention is as follows.

중간층(5)은 접착제층(6)의 상부에 수지 조성물을 여러번 도포하여 굳히므로서 이루어진다.The intermediate | middle layer 5 is made by apply | coating and hardening a resin composition on the upper part of the adhesive bond layer 6 several times.

본 발명의 수지 조성물을 접착제층(6)의 상부에 여러번 도포하여 굳히게되면 수지(10)에 골고루 분포되어 있는 첨가재(11)가 수지(10)의 결합강도를 증가시키게되어 전체적인 중간층(5)의 인장강도를 향상시키게 된다.When the resin composition of the present invention is hardened by coating the upper part of the adhesive layer 6 several times, the additive material 11 evenly distributed in the resin 10 increases the bonding strength of the resin 10, thereby increasing the bonding strength of the entire intermediate layer 5. It will improve the tensile strength.

또한, 첨가재(11)를 이루는 극세사(100)의 분할 보강사(101)가 넓게 퍼진 상태로 굳어지게 되므로 이또한 중간층(5)의 전체적인 인장강도를 더욱 향상시키게되는 효과를 기대할 수 있게된다.In addition, since the split reinforcement yarn 101 of the microfiber 100 forming the additive material 11 is hardened in a wide spread state, it is also possible to expect the effect of further improving the overall tensile strength of the intermediate layer 5.

도 5 는 본 발명의 수지 조성물을 이용하여 시공한 중간층(5)의 평단면을 부분 확대한 것으로 중간층(5)에 다수의 첨가재(11)가 넓게 분포되어 있으면서 중간층(5)의 인장강도를 향상시키고 있음을 확인할 수 있다.5 is a partially enlarged planar cross section of the intermediate layer 5 constructed using the resin composition of the present invention, and the tensile strength of the intermediate layer 5 is improved while a plurality of additives 11 are widely distributed in the intermediate layer 5. It can be confirmed that.
