본 발명은 아크릴 수지(Acryics resin) 접합용 중합 접착제의 제조방법에 관한 것으로, 상세하게는 경화 후 아크릴 수지 경도와 동일한 경도를 유지하므로써 접합부 돌출부의 제거가 용이하여 표면처리의 효율을 높여 접합작업을 용이하게 할 수 있도록 한 것으로, 특히 다색의 아크릴 수지로 구성하는 차량용 램프 커버의 접합에 적합한 아크릴 수지 접합용 중합 접착제의 제조방법에 관한 것이다.The present invention relates to a method for producing a polymer adhesive for acrylic resin (Acryics resin) bonding, and in detail, by maintaining the hardness of the acrylic resin after curing, it is easy to remove the protrusions of the joint portion to increase the efficiency of the surface treatment to improve the bonding operation The present invention relates to a method for producing a polymerizable adhesive for acrylic resin bonding, which is particularly suitable for joining a vehicle lamp cover composed of a multicolored acrylic resin.
차량용 램프커버는 아크릴산이나 아크릴산 유도체의 중합체인 황색·적색·백색의 아크릴 수지로 이루어진 각 부재를 용도에 따라 조합시킨 후 각 부재의 조합면에 접착제를 도포하여 접합시켜, 일체형으로 구성한 것으로, 종래에는 상기한 아크릴 수지의 접합을 위해 각 부재의 조합면에 순간 접착제를 도포 또는 침투시켜 일체로 접합하므로써 차량용 램프 커버를 구성하였다. 그러나 상기한 바와 같은 순간 접착제에 의한 아크릴 수지 접합 방법은, 접합후 경화된 순간접착제와 접합면에 표시가 나므로써 외관이 좋지 않았고, 각 접합면에 틈새가 있을 경우에는 순간 접착제의 특성상 틈새를 메우지 못해 강도가 약해지는 한편, 점도가 낮은 액상의 순간접착제의 취급에도 많은 어려움이 있었다.The vehicle lamp cover is formed by combining each member made of yellow, red and white acrylic resins, which are polymers of acrylic acid or acrylic acid derivatives, according to the application, and then applying an adhesive to the combined surfaces of the respective members to form an integral structure. In order to bond the acrylic resin described above, a vehicle lamp cover was constructed by applying a temporary adhesive to the combined surface of each member or infiltrating it integrally. However, in the acrylic resin bonding method using the instant adhesive as described above, the appearance was not good due to the marking on the bonded instantaneous adhesive and the bonding surface. While the strength was weakened due to the inability to hold, there were many difficulties in the handling of a liquid adhesive having a low viscosity.
본 발명의 목적은 상기한 종래의 문제점을 해결하여 경화후에 접착제와 아크릴 수지가 동일한 경도를 갖도록 하여 표면처리 효율을 높이고 표면 처리 작업을 용이하게 할 수 있도록 한 것으로, 이하 첨부된 도면과 함께 상세히 설명한다.An object of the present invention is to solve the above-mentioned problems and to make the adhesive and the acrylic resin have the same hardness after curing to increase the surface treatment efficiency and to facilitate the surface treatment operation, it will be described in detail with the accompanying drawings. do.
본 발명에 의한 아크릴 수지 접합용 중합 접착제의 제조방법은 제1도의 블록도로서 도시한 바와같이, 메탈크릴산(Methacrylicacid) 1ℓ에 [C(CH3)2C(CN) : (CH3)2CN]의 구조를 갖는 메타크릴산 경화제 2g을 혼합하는 단계(1공정)와, 상기한 혼합액을 95℃ 이상으로 가열된 수중에서 혼합액의 온도가 90~95℃에 이르도록 중탕을 하는 단계(II 공정)와, 90~95℃에 이르도록 재중탕하는 단계(IV 공정)와, 90~95℃의 혼합액을 상온으로 급냉한 후 대기중에서 서냉시키는 단계(V 공정)로 이루어진 공정에 의해 아크릴 수지와 경도와 동일한 경도를 갖는 아크릴 수지 접합용 중합 접착제를 제조한다.According to the present invention, a method for producing a polymer adhesive for bonding acrylic resins is shown in FIG. 1 as a block diagram. In 1 L of metalcrylic acid, [C (CH 3 ) 2 C (CN): (CH 3 ) 2 CN] step of mixing 2 g of methacrylic acid curing agent having a structure (step 1), and performing a hot bath so that the temperature of the mixed solution reaches 90 ~ 95 ℃ in water heated above 95 ℃ (II) Step), a step of re-bathing up to 90-95 ° C. (step IV), and a step of rapidly cooling the mixture liquid at 90-95 ° C. at room temperature, followed by slow cooling in air (V step). The polymer adhesive for acrylic resin bonding which has hardness equivalent to hardness is manufactured.
한편, 혼합액을 조성하는 제1공정에서, 제조가 완료되는(V) 과정까지의 전 공정중에는 균질한 혼합액을 얻고 동일한 온도조건이 되도록 혼합액이 되도록 혼합액을 충분히 교반시키므로써 불량을 방지하도록 하며, 전술한 III 공정과 IV 공정의 반복횟수를 조절하므로써 제조되는 아크릴 접합용 중합 접착제의 점도를 조절한다.On the other hand, in the first step of forming a mixed solution, during the entire process up to the process of manufacturing (V), a homogeneous mixed solution is obtained and the mixed solution is sufficiently stirred so that the mixed solution is brought to the same temperature conditions, thereby preventing defects. The viscosity of the polymer adhesive for acrylic bonding produced is controlled by controlling the number of repetitions of steps III and IV.
즉, 통상적인 점도를 갖는 아크릴 접합용 중합 접착제의 제조시에는 상기한 III 공정과 IV 공정을 3 내지 4회 정도 반복시켜 적정 점도를 갖는 아크릴 접합용 중합 접착제를 제조하며, 점도가 높은 아크릴 접합용 중합 접착제의 경우에는 III 공정과 IV 공정을 다수 반복하여 고점도의 아크릴 접합용 중합 접착제를 제조한다.That is, in the preparation of the acrylic adhesive polymer adhesive having a conventional viscosity, the above-described steps III and IV are repeated about 3 to 4 times to produce an acrylic adhesive polymer adhesive having an appropriate viscosity, and the acrylic adhesive for high viscosity In the case of the polymer adhesive, a plurality of steps III and IV are repeated to produce a polymer adhesive for high viscosity acrylic bonding.
상기한 방법에 의해 제조된 아크릴 접합용 중합 접착제의 사용예를 이하 제2도 및 3도로써 설명한다.Examples of use of the acrylic adhesive polymer adhesive prepared by the above method will be described with reference to FIGS. 2 and 3 below.
제2도는 본 발명에 의한 아크릴 접합용 중합 접착제가 적용되는 자동차용 테일라이트 커버(10)의 일례를 도시한 것으로, 일반적으로 적색의 아크릴로 이루어진 차폭 및 브레이크등 커버(5)의 내부에 백색의 후진등(3)과 황색의 방향 지시등(1)을 조합하여 이루어진 테일라이트 커버(10)의 각 접합면을,제3도에 도시한 바와 같이 외측이 확개부를 이루는 경사면으로 가공한 다음, 그 대향면에 본 발명에 의한 접착제의 누출을 방지하도록 셀룰로오스 필름(15) 등을 밀착시킨 후 스카치테입 등으로 고정시키고 경사면에 본 발명에 의해 제조된 접착제를 주입한다.FIG. 2 shows an example of a taillight cover 10 for a vehicle to which the acrylic adhesive polymer adhesive according to the present invention is applied, and generally has a white color inside a vehicle width and brake light cover 5 made of red acrylic. Each joining surface of the taillight cover 10 formed by combining the reversing light 3 and the yellow turn signal 1 is processed into an inclined surface whose outer side forms an enlarged portion as shown in FIG. In order to prevent the leakage of the adhesive according to the present invention on the surface, the cellulose film 15, etc. are brought into close contact with the scotch tape and the like, and the adhesive prepared by the present invention is injected into the inclined surface.
상기한 접착제의 경화는 통상적으로 4시간 경과하면 이루어지는데, 경화를 요할 경우에는 경화촉진 효과가 있는 자외선 형광등을 조사하므로써 경화시간을 단축시킨다.The curing of the adhesive is usually carried out after 4 hours. When curing is required, curing time is shortened by irradiating an ultraviolet fluorescent lamp having a curing promoting effect.
접착제의 경화가 완전히 이루어진 다음에는 표면에 튀어나온 접착제의 돌출 경화부를 사상작업 등으로 제거한 후 광택작업을 실시하므로써 완료한다.After the curing of the adhesive is completely completed, remove the protruding hardened portion of the adhesive protruding from the surface by finishing work, etc., and then finish it by polishing.
상기한 바와 같이 실시하는 본 발명은 경화후 아크릴 수지의 경도와 동일한 경도를 유지하므로써 접합후 돌출부의 제거가 용이하여 표면처리의 효율을 높여 작업을 용이하게 할 수 있는 한편, 각 부재에 간극이 생겼을 때에는 밀폐작업이 용이하므로써 접합부에 미려한 외관을 얻는 효과가 있다.According to the present invention carried out as described above, by maintaining the same hardness as the acrylic resin after curing, it is easy to remove the protrusions after bonding, thereby increasing the efficiency of the surface treatment and facilitating the work. In this case, it is possible to obtain a beautiful appearance by joining to the joint easily by sealing.
