이하 첨부된 도면을 참조로 본 발명의 바람직한 실시예를 상세히 설명하도록 한다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해석되어서는 아니되며, 발명자는 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in this specification and claims should not be construed as being limited to the usual or dictionary meaning, and the inventor appropriately uses the concept of the term in order to explain his/her invention in the best way. It should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.
따라서, 본 명세서에 기재된 실시예와 도면에 도시된 구성은 본 발명의 가장 바람직한 일 실시예에 불과할 뿐이고 본 발명의 기술적 사상을 모두 대변하는 것은 아니므로, 본 출원시점에 있어서 이들을 대체할 수 있는 다양한 균등물과 변형 예들이 있을 수 있음을 이해하여야 한다.Therefore, since the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, various alternatives may be used at the time of this application. It should be understood that there may be equivalents and variations.
이하, 도 1을 참조하여 본 발명의 바람직한 실시예에 따른 체결나사용 고내식성 마찰계수 안정제를 상세히 설명하도록 한다.Hereinafter, a highly corrosion resistant friction coefficient stabilizer for fastening screws according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 1 .
본 발명의 체결나사용 고내식성 마찰계수 안정제는 하기와 같다.The high corrosion resistance friction coefficient stabilizer for fastening screws of the present invention is as follows.
도금처리된 볼트 또는 스크류 등과 같은 체결나사를, 본 발명의 마찰계수 안정제로 코팅처리한 후 건조시킴으로써, 체결나사의 마찰계수(토크계수)를 햐향조정시키고 내식성을 향상시킬 수 있도록 하는 것이다.By coating a fastening screw such as a plated bolt or screw with the friction coefficient stabilizer of the present invention and then drying it, the friction coefficient (torque coefficient) of the fastening screw can be adjusted downward and corrosion resistance can be improved.
이러한 본 발명의 마찰계수 안정제는, 마찰계수 안정제 100중량부에 대하여, 5 내지 20중량부를 포함하는 증류수에 하기의 수지를 혼합하는 것으로, 더욱 상세하게는 5 내지 20중량부를 포함하는 증류수에 나머지 중량부는 에폭시(Epoxy)계 수지에, 액의 침강 및 엉킴현상을 발생시키기 않고, 경화온도를 낮추기 위한 왁스(Wax)계 수지가 상호간 사전설정비율로, 상기 증류수에 혼합시킨 것이다. (단독으로 Wax계(Paraffin계) 수지만 사용시 내식성 저하의 문제가 있을 수 있기 때문에 2개의 수지를 혼합하여 사용하는 것이고, 에폭시계 수지와 수계 왁스를 일정 비율로 혼합하여 내식성을 향상시키는 것이다.)The friction coefficient stabilizer of the present invention is to mix the following resin in distilled water containing 5 to 20 parts by weight based on 100 parts by weight of the friction coefficient stabilizer, more specifically, the remaining weight to distilled water containing 5 to 20 parts by weight. The epoxy resin is mixed with the distilled water at a predetermined ratio of a wax resin to lower the curing temperature without causing sedimentation and entanglement of the liquid. (Since there may be a problem of corrosion resistance degradation when using wax-based (Paraffin-based) resin alone, two resins are mixed and used, and corrosion resistance is improved by mixing epoxy resin and water-based wax in a certain ratio.)
상기의 에폭시계 수지는 실리케이트(Silicate) 및 아크릴레이트(Acrylate), 우레탄(Urethane) 수지 중 하나가 사용되는 것이며,The above epoxy-based resin is one of silicate, acrylate, and urethane resin,
상기의 Wax계(Paraffin계) 수지를 사용하게 되면, 별도의 마찰계수 안정화 물질이 첨가되지 않으므로, 액의 침강 및 엉킴 현상을 없앨 수 있고, 경화 온도를 낮출 수 있는 이점을 가지고 있다.When the wax-based (Paraffin-based) resin is used, since no additional friction coefficient stabilizing material is added, settling and entanglement of the liquid can be eliminated and the curing temperature can be lowered.
상기 에폭시계 수지와 왁스계 수지의 중량부 비율은, 체결나사의 종류 또는 체결나사가 적용되는 차량종류 등 다양한 적용조건에 따라, 상호간 1:1 또는 2:3 비율로 혼합하여 사용하도록 한다.The weight ratio of the epoxy-based resin and the wax-based resin is used in a 1: 1 or 2: 3 ratio according to various application conditions such as the type of fastening screw or the type of vehicle to which the fastening screw is applied.
일실시예로는 도 1에 도시된 바와 같이, 체결나사의 1종 조건의 범위(1종 만족이라 표시된 빨간색 사각 점선칸 상에 표시된 2개의 빨간선 사이)에 만족되도록 에폭시계 수지(ex: 우레탄)와 왁스계 수지를 1:1 비율로 혼합하고. 이를 20% 증류수와 혼합한 마찰계수 안정제를 사용한 것이고,In one embodiment, as shown in FIG. 1, an epoxy resin (ex: urethane ) and a wax-based resin in a 1:1 ratio. A friction coefficient stabilizer mixed with 20% distilled water was used,
또는 체결나사의 3종 조건의 범위(3종 만족이라 표시된 파란색 사각 점선칸 상에 표시된 2개의 파란선 사이)에 만족되도록 에폭시계 수지(ex: 우레탄)와 왁스계 수지를 2:3 비율로 혼합하고. 이를 15% 증류수 또는 20% 증류수와 혼합한 마찰계수 안정제를 사용한 것이다.Or mix epoxy resin (ex: urethane) and wax resin at a ratio of 2:3 to satisfy the range of 3 types of fastening screws (between the 2 blue lines marked on the blue square dotted line marked as satisfying 3 types) do. A friction coefficient stabilizer mixed with 15% distilled water or 20% distilled water was used.
이러한, 본 발명의 마찰계수 안정제를 사용함에 따라, 안정제 사용대상이 되는 체결나사의 마찰계수를 기존의 마찰계수 0.25 ~ 0.45에서 0.10 ~ 0.16까지 저감시킬 수 있어서, 체결 안정성을 확보할 수 있는 것이다.According to the use of the friction coefficient stabilizer of the present invention, the friction coefficient of the fastening screw to be used for the stabilizer can be reduced from the existing friction coefficient of 0.25 to 0.45 to 0.10 to 0.16, thereby securing fastening stability.
상기 조성물에 포함되는 에폭시계 수지는 내식성에 안정적인 물성을 나타내지만, 가혹한 조건의 산소나 물, 기타 온도에 대한 적응력은 만족할 수 없으므로, 본 발명에서는 첨가제를 사용하여 내식성을 향상시킨다.Although the epoxy-based resin included in the composition exhibits stable physical properties for corrosion resistance, adaptability to oxygen, water, and other temperatures under harsh conditions is not satisfactory. In the present invention, corrosion resistance is improved by using additives.
이와 같은 첨가제로는 가교제, 수계 왁스, 경화제 중 어느 하나 또는 2개 이상이 사용될 수 있다.As such an additive, any one or two or more of a crosslinking agent, a water-based wax, and a curing agent may be used.
이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변경이 가능함은 물론이다.As described above, although the present invention has been described by the limited embodiments and drawings, the present invention is not limited thereto, and the technical spirit of the present invention and the following by those skilled in the art to which the present invention belongs Of course, various modifications and changes are possible within the scope of equivalents of the claims to be described.
