본 발명은 필터망에 대한 접착력이 우수하면서 유연성이 뛰어난 필터테를 갖춘 자동차 공기조화기용 에어필터에 관한 것이다.The present invention relates to an air filter for a car air conditioner having a filter frame having excellent adhesive force to a filter network and excellent flexibility.

일반적으로, 자동차 공기조화기에서, 자동차의 실내에 공기를 순환시키는 공기순환유니트에는 증발기가 배설되어 있고, 상기 증발기를 통과하는 공기를 필터링하도록 상기 필터가 상기 증발기의 일측에 배설되어 있다.In general, in an automobile air conditioner, an evaporator is disposed in an air circulation unit that circulates air in an interior of an automobile, and the filter is disposed on one side of the evaporator to filter the air passing through the evaporator.

종래 자동차 공기조화기용 에어필터는 제1도에 도시한 바와 같이, 접착제에 의해 일정한 강성을 가진 필터프레임(1)의 내면에 필터망(3)이 접합되어 있었다.In the conventional air filter for automobile air conditioners, as shown in FIG. 1, the filter net 3 is bonded to the inner surface of the filter frame 1 having a fixed rigidity by an adhesive agent.

또한, 종래 다른 예로서, 제2도에 도시한 바와 같이, 일정한 강성을 가진 필터프레임(5)의 상측 또는 하측면에 나사부재(7)에 의해 필터망(9)이 고정되어 있었다.In addition, as another conventional example, as shown in FIG. 2, the filter net 9 was fixed by the screw member 7 to the upper side or the lower side of the filter frame 5 with fixed rigidity.

이때, 상기 필터프레임(1,5)은 사각테형상으로서, 폴리플로필렌등의 재질로 되어 있다.At this time, the filter frame (1, 5) is a rectangular rim, made of a material such as polypropylene.

그런데, 이와같이 구성된 조래의 에어필터는 필터프레임(1,5)의 강성으로 인하여 구부려지지 않으므로, 일정한 공간상의 제약을 받는 자동차 공기조화기에서 그 협소한 공간에 에어필터를 설치하기가 용이하지 않다는 문제점이 있었다.By the way, since the air filter of Chorae constructed in this way is not bent due to the rigidity of the filter frames (1, 5), it is not easy to install the air filter in the narrow space in a car air conditioner subject to a certain space constraints. There was this.

상기한 바와 같은 문제점을 해결하기 위하여 고무등 유연한 재질의 필터테를 필터망의 가장자리에 접합한 에어필터가 제안되어 있으나, 상기 필터테를 형성하기가 용이하지 않을 뿐만 아니라, 이 필터테는 에어필터의 필터망에 접착력이 우수하지 못하다는 문제점이 있었다.In order to solve the above problems, there has been proposed an air filter in which a filter frame made of a flexible material such as rubber is bonded to the edge of the filter network, but it is not easy to form the filter frame. There was a problem in that the adhesive force is not excellent in the filter net.

따라서, 본 발명은 상기 문제점들을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 필터망에 대한 접착력이 우수하면서 유연성이 뛰어난 필터테를 갖춘 자동차 공기조화기용 에어필터를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide an air filter for an automobile air conditioner with a filter frame having excellent flexibility and excellent flexibility to the filter network.

상기 목적을 달성하기 위한 본 발명에 의한 자동차 공기조화기용 에어필터는 폴리에스테르(POLYESTER) 100 중량부에 대해 이소시아나이트(ISOCYNATE) 20~40중량부로 이루어지는 필터테를 갖춘 것을 특징으로 한다.Air filter for a vehicle air conditioner according to the present invention for achieving the above object is characterized by having a filter frame consisting of 20 to 40 parts by weight of isocyanate (ISOCYNATE) with respect to 100 parts by weight of polyester (POLYESTER).

이때, 상기 이소시아나이트(ISOCYNATE)는 폴리에스테르(POLYESTER) 100 중량부에 대해 28중량부로 이루어지는 것이 특히 바람직하다.At this time, the isocyanate (ISOCYNATE) is particularly preferably made of 28 parts by weight based on 100 parts by weight of polyester (POLYESTER).

그리고, 상기 폴리에스테르(POLYESTER)는 SQ-R(상품명)등이 사용가능하고, 상기 이소시아나이트(ISOCYNATE)는 SQ-I(상품명)등이 사용가능하지만, 이에 제한받지 않는다.The polyester (POLYESTER) can be used SQ-R (trade name) and the like, the isocyanate (ISOCYNATE) can be used SQ-I (trade name) and the like, but is not limited thereto.

이하, 본 발명이 적용된 자동차 공기조화기용 에어필터의 제조방법의 일예에 대해 제3a도 내지 제3d도에 따라 설명한다.Hereinafter, an example of a method of manufacturing an air filter for an automobile air conditioner to which the present invention is applied will be described with reference to FIGS. 3A to 3D.

먼저, 제3a도의 S1공정에서는 다공질의 섬유로 된 필터원재를 일정한 크기로 절단하여 산형상으로 절첩하여 필터망재(11a)를 만들고, 그 일측면이 랙의 잇빨형상으로 된 한쌍의 치구(J)를 준비하여 상기 한쌍의 치구(J)를 상기 필터재(11a)의 일측부의 산형상에 끼워 상기 필터망재(11a)를 고정한다.First, in the step S1 of FIG. 3a, the filter material made of porous fibers is cut to a certain size, folded into an acid shape to form a filter net material 11a, and a pair of jigs J having one side thereof as a tooth shape of a rack. And a pair of jig (J) is fitted on the mountain shape of one side of the filter material (11a) to fix the filter net material (11a).

다음에, 제3b도의 S2공정에서는 요입공간(Da)을 가진 금형(D)을 준비하여 기 제조된 액상의 필터테 조성물(13a)을 주입통(I)을 통해 상기 금형(D)의 요입공간(Da)에 주입한다.Next, in the step S2 of FIG. 3B, the mold D having the indentation space Da is prepared, and the preformed liquid filter frame composition 13a is injected through the infusion tube I. Inject in (Da).

이때, 상기 액상의 필터테 조성물(13a)은 폴리에스테르(POLYESTER)와 이소시아나이트(ISOCYNATE)를 50℃에서 혼합하여 배합한 후, 도시하지 않은 믹서에 넣어 믹싱함에 의해 제조한다.In this case, the liquid filter frame composition 13a is prepared by mixing and mixing polyester (POLYESTER) and isocyanate (ISOCYNATE) at 50 ° C., and then mixing the mixture into a mixer (not shown).

그리고, 상기 액상의 플라스틱재는 상기 폴리에스테르(POLYESTER) 100 중량부에 대해 이소시아나이트(ISOCYNATE) 28중량부에 배합한다.The liquid plastic material is blended with 28 parts by weight of isocyanate (ISOCYNATE) based on 100 parts by weight of the polyester (POLYESTER).

또한, 상기 액상의 필터테 조성물(13a)을 상기 금형(D)에 주입할 때의 온도는 30℃로 한다.In addition, the temperature at the time of inject | pouring the said liquid filter frame composition 13a into the said metal mold | die (D) shall be 30 degreeC.

다음에, 제3c도의 S3공정에서는 상기 치구(J)에 의해 고정된 상기 필터망재(11a)의 일단부를 상기 금형(D)이 요입공간(Da)에 삽입하여 일정한 시간을 유지시켜 액상의 필터테 조성물(13a)이 경화한 후, 상기 금형(D)을 상기 필터망재(11a)에서 분리하면, 상기 필터망재(11a)의 일측부에 하나의 필터테(13)가 형성된다.Next, in the step S3 of FIG. 3C, the mold D is inserted into the recessed space Da by holding one end of the filter net material 11a fixed by the jig J to maintain a constant time, thereby providing a liquid filter frame. After the composition 13a is cured, the mold D is separated from the filter net material 11a, and one filter frame 13 is formed at one side of the filter net material 11a.

다음에, 제3d도의 S4공정에서는 상기 치구(J)에 의해 고정된 상기 필터망재(11a)를 뒤집은 후, 상기 S2공정을 다시 수행하여 상기 필터망재(11a)의 타단부를 상기 금형(D)의 요입공간(Da)에 삽입하여 일정한 시간을 유지시켜 액상의 필터테 조성물(13a)이 경화한 후, 상기 금형(D)을 상기 필터망재(11a)에 분리하면, 상기 필터망재(11a)의 타측부에 하나의 필터테(13')가 형성되어, 제4도에 도시된 바와같은 에어필터가 완성된다.Next, in the step S4 of FIG. 3d, the filter mesh member 11a fixed by the jig J is overturned, and then the process S2 is performed again to form the other end of the filter mesh member 11a in the mold D. After the liquid filter frame composition (13a) is cured by inserting it into the indentation space (Da) of the liquid, the mold (D) is separated from the filter network material (11a), and the filter network material (11a) One filter frame 13 'is formed at the other side, thereby completing the air filter as shown in FIG.

이때, 상기 금형(D)의 요입공간(Da)에 주입된 액상의 필터테 조성물(13a)에 상기 필터망재(11a)가 삽입된 후, 반응/경화에 소요되는 시간은 CREME TIME(삽입후 발포가 시작되는 시간) 30~50초, RISE TIME(발포가 시작되어 끝나는 시간) 90~110초, TACK FREE TIME(발포가 끝나고 점성이 없어지는 시간) 3~5분, DEMOLD TIME(반응이 완료하는 시간) 5~9분이 필요하다.At this time, after the filter network material 11a is inserted into the liquid filter frame composition 13a injected into the inlet space Da of the mold D, the time required for reaction / curing is CREME TIME (foaming after insertion). 30 ~ 50 seconds, RISE TIME 90 ~ 110 seconds, TACK FREE TIME 3 ~ 5 minutes, DEMOLD TIME Time) 5-9 minutes are required.

이와같이 제조된 자동차 공기조화기용 에어필터는 유연성이 뛰어나므로, 공간상의 제약을 받는 자동차 공기조화기에서 그 협소한 공 간에서도 에어필터를 설치하기가 용이하고, 필터테는 필터망에 대한 접착력이 우수하므로 에어필터의 내구성이 양호한 것이다.Since the air filter for automobile air conditioners manufactured in this way has excellent flexibility, it is easy to install an air filter in a narrow space in a car air conditioner that is limited by space, and the filter frame has excellent adhesion to the filter network. Therefore, the durability of the air filter is good.

앞에서 설명한 바와 같이, 본 발명에 의한 자동차 공기조화기용 에어필터는 그 필터테가 필터망에 대해 접착력이 우수하면서 유연성이 뛰어난 효과가 있다.As described above, the air filter for a vehicle air conditioner according to the present invention has an excellent flexibility and excellent adhesion to the filter tega filter network.
