먼저, 본 발명의 일 실시 예에 따른 흡음재 제조과정을 도 1의 순서도를 통해 살펴보면 다음과 같다.First, looking at the sound absorbing material manufacturing process according to an embodiment of the present invention through the flow chart of Figure 1 as follows.

<스펀지 성형>(ST 1)<Sponge Molding> (ST 1)

먼저, 일정 탄력성을 갖는 폴리우레탄 등과 같은 합성수지재질의 경량형 다공성 스펀지(1)를 성형하게 된다.First, a lightweight porous sponge 1 of synthetic resin material such as polyurethane having a certain elasticity is molded.

이때 성형되어지는 스펀지(1)는 사용 용도에 따라 다양한 크기로 성형이 이루어질 수 있으며, 필요에 따라서는 흡음성능 향상을 고려하여 상면을 요철형상으로 형성할 수도 있게 된다.In this case, the sponge 1 to be molded may be formed in various sizes according to the intended use, and if necessary, the upper surface may be formed into an uneven shape in consideration of improvement of sound absorption performance.

<몰탈 침적>(ST 2)Mortar Deposition (ST 2)

이와 같이 성형된 스펀지(1)는 도 2a 및 도 2b에서와 같이 시멘트 몰탈(11)이 일정 수위로 조정된 몰탈수조(10)에 투입하여 침적시키는 작업을 수행하게 된다.The sponge 1 thus formed is put into the mortar dewatering tank 10 in which the cement mortar 11 is adjusted to a predetermined level, as shown in FIGS. 2A and 2B.

특히, 스펀지(1)를 몰탈수조(10)에 투입한 후에는 몰탈이 스펀지의 공극으로 용이하게 스며들수 있도록 도 2c에서와 같이 방망이(20)를 이용하여 스펀지(1)를 수회 눌러주는 동작을 수행함이 바람직한데, 이와 같이 방망이(20)로 눌러주게 되면 스펀지(1)내 공기가 강제 배출되어지면서 시멘트몰탈이 스펀지내로 용이하게 유입되어질 수 있게 된다.In particular, after the sponge (1) is put into the mortar tank 10, the operation of pressing the sponge 1 several times using the bat 20 as shown in Figure 2c so that the mortar can easily penetrate into the void of the sponge It is preferable to perform this, when the bat 20 is pressed in this way, the air in the sponge 1 is forced out of the cement mortar can be easily introduced into the sponge.

한편, 몰탈수조(10)에 저장되는 시멘트 몰탈(11)은 결합제인 시멘트에 강도강화 및 표면경도 향상을 위한 보조결합제 및 유기결합제가 혼합되어지되, 상기 보조결합제는 분말유리, 규사, 펄라이트, 규조토, 화산재 중 하나 이상이 선택되어지며, 상기 유기결합제는 아크릴에멀젼, 아크릴-코폴리머화합물, 에틸-부틸비닐아크릴 코폴리머유도체, 실란유도체, 수용성 우레탄수지, 메틸 셀룰로오스, CMC(carboxymethyl cellulose) 중 하나 이상이 선택되어지게 된다.On the other hand, the cement mortar (11) stored in the mortar dewatering tank (10) is mixed with a binder cement and an auxiliary binder and an organic binder for improving the strength and surface hardness, the auxiliary binder is powder glass, silica sand, pearlite, diatomaceous earth At least one of volcanic ash is selected, and the organic binder is at least one of an acrylic emulsion, an acrylic copolymer compound, an ethyl-butyl vinyl acrylic copolymer derivative, a silane derivative, a water-soluble urethane resin, methyl cellulose, and carboxymethyl cellulose (CMC). Will be selected.

즉, 시멘트 몰탈(11) 조성물의 일 예로서 물 30~70중량%, 결합제 5~50중량%, 보조결합제 3~40중량%, 유기결합제 0.5~30중량%의 혼합범위로 혼합이 이루어짐이 바람직하다.That is, as an example of the cement mortar (11) composition is preferably mixed in the mixing range of 30 to 70% by weight of water, 5 to 50% by weight of the binder, 3 to 40% by weight of the auxiliary binder, 0.5 to 30% by weight of the organic binder. Do.

상기에서 결합제는 포틀란트시멘트, 슬라그시멘트, 백시멘트, 알루미나시멘트, 석탄재 등이 선택적으로 사용되어질 수 있게 된다.In the binder, portant cement, slag cement, back cement, alumina cement, coal ash, etc. may be selectively used.

또한, 시멘트 몰탈 제조과정에서 기능성 향상을 위해 기능성 결합제를 추가로 첨가하거나, 또는 점도 조절을 위한 유동화제 및 공극 조절을 위한 기포제가 각각 0.1~ 5중량% 범위내에서 첨가되어질 수 있게 된다.In addition, in the cement mortar manufacturing process, an additional functional binder may be added to improve functionality, or a fluidizing agent for adjusting viscosity and a foaming agent for controlling voids may be added in a range of 0.1 to 5% by weight, respectively.

그중 기능성 결합제로는 황토, 숯가루, 은나노 가 선택적으로 사용될 수 있는데, 특히 은나노는 항균 및 탈취기능을 갖기 때문에 실내 장식재로 사용되는 흡음재에 사용함이 바람직하다.Among them, ocher, charcoal powder, and silver nano may be selectively used as the functional binder. Particularly, silver nano is preferably used as a sound absorbing material used as an interior decoration material because it has antibacterial and deodorizing function.

또한, 유동화제는 아크릴산유도체, 멜라민유도체 가 선택적으로 사용됨으로서 몰탈의 점성을 부드럽게 해서 작업성을 향상시키도록 하게 된다.In addition, the fluidizing agent is used to selectively improve the workability by softening the viscosity of the mortar by using acrylic acid derivatives, melamine derivatives selectively.

또한, 기포제를 혼합하는 방법은 직접혼합법 또는 프리폼 혼합법이 사용되어질 수 있게 되는데, 이때 사용되는 기포제는 여러가지 기포제 종류 중 시멘트 성분과 기포반응성이 뛰어난 디아조아미노벤젠을 첨가함이 바람직하다.In addition, the method of mixing the foaming agent can be used a direct mixing method or a preform mixing method, wherein the foaming agent used is preferably added to the diazoaminobenzene excellent foaming reactivity with the cement component of the various foaming agent types.

이 외에도 필요에 따라 안료 등이 소량 첨가되어질 수 있게 된다.In addition to this, a small amount of pigment or the like may be added as necessary.

<몰탈수조 이탈>(ST 3)<Mortal dewatering tank leaving> (ST 3)

몰탈수조 이탈단계(ST 3) 에서는 상기와 같은 조성을 이루는 시멘트 몰탈이 내부 공극에 고르게 침적된 스펀지(1)를 몰탈수조(10)로 부터 꺼내어 주게 된다.In the mortar dewatering step (ST 3), the cement mortar forming the composition as described above is taken out of the sponge 1 from the mortar dewatering tank 10 evenly deposited in the internal voids.

<프레스(비중조절)>(ST 4)Press (weight control) (ST 4)

그리고, 스펀지(1)를 가압프레스(30)를 이용하여 일정 압력으로 가압시킴으로서 내부에 침적된 시멘트 몰탈을 일정량 배출시켜 몰탈의 적정비중을 조절해 주게 된다.Then, by pressing the sponge (1) at a predetermined pressure by using a pressure press 30 to discharge a certain amount of cement mortar deposited therein to adjust the appropriate weight of the mortar.

이때, 스펀지(1)의 비중이 200~300㎏/㎥ 의 범위를 만족하도록 프레스 압력을 조절해야 하는데, 비중이 200㎏/㎥ 이하인 경우에는 방화기능이 저하되어지게 되며, 비중이 300㎏/㎥ 이상이 되게 되면 내부 공극률이 낮아지게 됨으로서 흡음성능을 저해하게 된다.At this time, the press pressure should be adjusted so that the specific gravity of the sponge 1 satisfies the range of 200 ~ 300㎏ / ㎥, if the specific gravity is less than 200㎏ / ㎥, the fire protection function is lowered, the specific gravity is 300㎏ / ㎥ When the abnormality is lowered, the internal porosity is lowered, thereby inhibiting the sound absorption performance.

따라서, 가압프레스(30)에 가해지는 프레스 압력을 조금씩 증가시키면서 수회에 걸쳐 가압을 실시함으로서 적절한 비중을 조절함이 바람직하다.Therefore, it is preferable to adjust an appropriate specific gravity by performing pressurization several times, while increasing the press pressure applied to the pressurization press 30 little by little.

<건조>(ST 5)<Drying> (ST 5)

상기와 같이 비중조절이 완료된 스펀지(1)는 몰탈이 경화되어지도록 15~30℃에서 10~20시간 동안 건조시키는 건조과정 및 양생과정을 거침으로서 고형화 되어진 흡음재의 제작이 완료되어지게 된다.As described above, the sponge 1 of which the specific gravity control is completed is completed to manufacture the sound absorbing material that has been solidified by undergoing a drying process and a curing process of drying at 15 to 30 ° C. for 10 to 20 hours so that the mortar is cured.

이와 같은 과정을 통해 제작되어진 본 발명의 스펀지 흡음재는 스펀지 재료로 인해 내부의 공극이 일정범위로 확보되어짐으로서 최적의 흡음효과를 나타냄과 함께 시멘트 몰탈로 인해 화재로 부터 안전성이 확보되어질 수 있게 된다.The sponge sound absorbing material of the present invention manufactured through such a process can be secured from fire due to cement mortar while exhibiting an optimal sound absorbing effect as the voids inside are secured to a certain range due to the sponge material.

특히, 다공질 구조로 인한 제품의 경량성, 단열성, 탈취 및 습도조절 기능 등 다양한 기능성을 확보하게 되어, 음악실이나 방송실 등과 같은 실내 인테리어 마감재로 사용되거나, 또는 도로 방음벽, 터널벽 등 다양한 용도로 활용되어질 수 있게 된다.
In particular, it has various functionalities such as light weight, insulation, deodorization, and humidity control functions of the product due to the porous structure, and can be used as interior finishing materials such as music room or broadcasting room, or for various purposes such as road soundproof wall and tunnel wall. It becomes possible.

한편, 도 4는 본 발명의 다른 실시 예에 따른 스펀지 흡음재 제조과정을 나타낸 것으로서, 형틀투입단계(ST 2-1)에서는 성형된 스펀지를 몰탈형틀에 투입시킨 후, 몰탈 주입단계(ST 2-2)에서 몰탈형틀에 정해진 일정량의 시멘트몰탈을 주입시켜 몰탈이 스펀지의 공극으로 스며들도록 하게 되는 것이다.On the other hand, Figure 4 shows a sponge sound absorbing material manufacturing process according to another embodiment of the present invention, in the mold input step (ST 2-1), after the molded sponge is injected into the mortar mold, a mortar injection step (ST 2-2 ), A certain amount of cement mortar is injected into the mortar mold so that the mortar penetrates into the pores of the sponge.

즉, 스펀지와 동일한 크기 및 형상으로 몰탈형틀을 제작하여 비중이 200~300㎏/㎥ 로 맞춰질 수 있는 량의 시멘트몰탈을 형틀에 주입한 후 방망이를 이용하여 스펀지를 수회 눌러줌으로서 주입된 몰탈이 전량 스펀지내로 유입되어질 수 있게 된다.In other words, by making a mortar mold with the same size and shape as the sponge, and injecting the cement mortar of the amount can be adjusted to 200 ~ 300 ㎏ / ㎥ into the mold, the mortar injected by pressing the sponge several times using a bat. The whole amount can be introduced into the sponge.

이와 같이 몰탈이 주입된 스펀지를 몰탈형틀로 부터 이탈시키는 이탈단계(ST 3)를 수행한 후 프레스 가압작업 없이 곧바로 건조작업을 실시하여 흡음재의 제작이 완료되어질 수 있게 되는 것이다.As described above, after performing the detachment step (ST 3) of detaching the mortar-injected sponge from the mortar-type mold, the drying operation is performed immediately without press pressurization, thereby producing a sound absorbing material.

따라서, 이러한 다른 실시 예에 의한 몰탈 주입식 방법은 상기 일 실시 예에 따른 몰탈수조를 이용하는 침적법에 비해 몰탈의 리사이클이 줄어들게 되어 적정비중을 맞추는데 유용하게 되고, 따라서 별도로 프레스 가압을 실시하는 과정이 필요없게 됨으로서 제조과정을 단축시킴과 함께 몰탈의 낭비를 방지하는 이점을 나타낼 수 있게 된다.Therefore, the mortar injection method according to another embodiment of the present invention is useful to meet the appropriate specific gravity by reducing the recycling of mortar compared to the deposition method using the mortar tank according to the above embodiment, and thus requires a process of separately pressing This can shorten the manufacturing process and present an advantage of preventing the waste of mortar.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 흡음재 제조과정이 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다.In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the manufacturing process of the sound absorbing material of the present invention may be variously modified and implemented by those skilled in the art.

예를 들면, 프레스 단계에서의 프레스 압력이나 또는 건조단계에서의 건조시간 및 온도 등은 상기 실시 예에서의 수치범위를 벋어나서 실시 될 수도 있게 된다.For example, the press pressure in the press step or the drying time and temperature in the drying step may be carried out beyond the numerical range in the above embodiment.

따라서, 이와 같은 변형된 실시예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.Therefore, it should be understood that such modified embodiments should not be understood individually from the technical spirit and scope of the present invention, and such modified embodiments should be included in the appended claims of the present invention.
