Description
본 발명은 샤워부스용 강화 아크릴판에 관한 것으로, 보다 상세하게는 강도가 높고 쉽게 깨지지 않아 안전하면서 내스크래치성은 물론 난연성까지 향상된 샤워부스용 강화 아크릴판에 관한 것이다.
The present invention relates to a reinforced acrylic plate for a shower booth, and more particularly, to a reinforced acrylic plate for a shower booth which has a high strength and is not easily broken, and which is safe and has improved scratch resistance as well as flame retardancy.
잘 알려진 바와 같이, 샤워부스는 이용자에게 밀폐된 공간을 제공하여 외부로부터의 간섭과 물튀김에 대한 우려없이 편안하게 샤워할 수 있도록 설치되는 욕실기구이다.As is well known, the shower booth is a bathroom appliance that is provided to provide a closed space for the user, so that the user can shower comfortably without fear of interference from outside and water splashing.
이러한 샤워부스는 벽체에 견고하게 고정되어 일정 공간을 구획하는 칸막이와, 칸막이에 의해 밀폐되어진 공간을 개폐시킬 수 있도록 회동가능하게 설치되는 도어로 이루어지는 것이 일반적이며, 등록실용 제0286547호를 비롯한 다수의 특허기술들에 개시되어 있다.Such a shower booth is generally composed of a partition which is firmly fixed to the wall and which divides a certain space and a door which is rotatably installed so as to open and close a space sealed by the partition, and a plurality of shower booths including a registration room No. 0286547 Are disclosed in patented technologies.
또한, 주거문화의 변화에 따라 아파트를 포함한 일반 가정집에서도 샤워부스의 설치는 보편화되었고, 최근에는 고정식 샤워부스 뿐만 아니라, 이동식 샤워부스도 개시되고 있는데, 관련 기술로는 공개특허 제2012-0115164호를 들 수 있다.In addition, according to the change of the residential culture, the installation of the shower booth has become commonplace in general households including apartments, and in recent years, not only a fixed shower booth but also a movable shower booth have been disclosed. As related technology, .
그런데, 종래 샤워부스의 경우 물이 튀는 것을 막기 위한 밀폐구조물로 유리를 택하고 있어 안전상 문제가 발생된다.However, in the case of a conventional shower booth, glass is selected as a hermetic structure for preventing water from splashing, which poses a safety problem.
유리는 투명 혹은 반투명을 사용하며, 내외를 볼 수 있기 때문에 공간의 협소함을 해소할 수 있어 폐쇄공포를 줄여 주기 때문에 심리적 안정감을 주는 장점은 있으나, 깨지면 상해를 입기 쉽고, 설치하기 어려우며, 무겁고, 특히 화재 발생시 내화성이 없어 매우 취약하다는 단점을 안고 있다.The glass is transparent or translucent, and can be seen inside and outside, so it can solve the narrowness of the space, which reduces the fear of closure, so it has the advantage of providing psychological stability. However, it is easy to get injured, difficult to install, heavy It has a disadvantage that it is very vulnerable because it is not fire-resistant when a fire occurs.
이와 같은 단점을 해소하기 위해 아크릴판이 대체사용되고 있다.In order to overcome such disadvantages, an acrylic plate has been used alternatively.
하지만, 아크릴판의 경우에도 난연성이 결여되어 있기 때문에 화재에 취약하고, 특히 강도가 약해 표면스크래치가 쉽게 발생하므로 외관 품질이 급격히 떨어지는 단점이 있다.However, even in the case of an acrylic plate, since it lacks flame retardancy, it is vulnerable to fire. In particular, it has a weak strength and a surface scratch easily occurs.
나아가, 샤워부스는 항상 물과 접촉해 있어야 하기 때문에 내식성도 강해야 하는데, 일반적인 아크릴판은 내부식성이 떨어지는 단점도 있고, 쉽게 오염되므로 위생측면에서도 바람직하지 못하다.
Furthermore, since the shower booth should always be in contact with water, the corrosion resistance must be strong. In general, the acrylic plate has a disadvantage that it is poor in corrosion resistance and is not preferable from the viewpoint of hygiene because it is easily contaminated.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 아크릴판의 강도를 현저히 강화시켜 내스크래치성을 증대시킴으로써 외관품질을 높일 수 있는 샤워부스용 강화 아크릴판을 제공함에 그 주된 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems in the prior art, and provides a reinforced acrylic plate for a shower booth, which can improve the appearance quality by enhancing the scratch resistance by significantly enhancing the strength of the acrylic plate There is a main purpose in.
또한, 본 발명은 샤워부스용으로 사용되는 강화 아크릴판에 특정 성분을 첨가시켜 난연성을 향상시켜 화재시 내화성을 증대시킬 수 있도록 함에 그 다른 목적이 있다.It is another object of the present invention to improve the flame retardancy by adding a specific component to a reinforced acrylic plate used for a shower booth, thereby enhancing fire resistance in case of fire.
뿐만 아니라, 본 발명은 샤워부스용으로 사용되는 강화 아크릴판에 특정 성분을 첨가시켜 이물 미끄럼성을 향상시킴으로써 내오염성을 증대시키고, 내부식성도 향상시킬 수 있도록 함에 그 또다른 목적이 있다.
Another object of the present invention is to add a specific component to a reinforced acrylic plate used for a shower booth to improve the slip resistance, thereby increasing stain resistance and improving corrosion resistance.
본 발명은 상기한 목적을 달성하기 위한 수단으로, 아크릴판을 열가마에 넣고 150~200℃의 온도로 가열한 다음 일정시간 동안 유지하면서 가소화시키고, 가소화 된 아크릴판을 무늬판이 구비된 상부금형과 하부금형 사이에 배치한 후 가압하면서 평평하게 레벨링하여 무늬판에 형성된 무늬가 상기 아크릴판의 표면과 이면에 압착과 동시에 새겨지게 한 것을 특징으로 하는 샤워부스용 강화 아크릴판을 제공한다.In order to achieve the above-mentioned object, the present invention provides a method for producing an acrylic plate, comprising the steps of placing an acrylic plate in a heating furnace, heating the mixture at a temperature of 150 to 200 ° C, maintaining the plate for a predetermined period of time, plasticizing the plasticized acrylic plate Wherein the patterned plate is placed between the mold and the lower mold and leveled while being pressed so that the pattern formed on the pattern plate is pressed and pressed on the front and back surfaces of the acrylic plate.
이때, 상기 상부금형과 하부금형에 구비된 무늬판에 새겨진 무늬는 서로 거울 대칭인 것에도 그 특징이 있다.At this time, the patterns engraved on the pattern plates provided in the upper mold and the lower mold are mirror-symmetrical to each other.

According to the present invention, by strengthening the strength of an acrylic plate for glass substitute used for a shower booth, it is possible to prevent cracking to increase safety, to increase fire resistance as well as scratch resistance, to increase fire resistance in case of fire, The effect of increasing the hygiene can be obtained.
도 1은 본 발명에 따른 샤워부스용 강화 아크릴판의 제조예를 보인 예시도이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an example of production of a reinforced acrylic plate for a shower booth according to the present invention.
이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.
또한, 본 발명의 개념에 따른 실시예는 다양한 변경을 가할 수 있고 여러 가지 형태를 가질 수 있으므로, 특정 실시예들은 도면에 예시하고 본 명세서에 상세하게 설명하고자 한다. 그러나, 이는 본 발명의 개념에 따른 실시예들을 특정한 개시 형태에 한정하려는 것이 아니며, 본 발명의 사상 및 기술 범위에 포함되는 모든 변경물, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
본 발명에 따른 샤워부스용 강화 아크릴판은 일반적인 공지의 아크릴판을 열처리하여 내스크래치성을 갖는 강화 아크릴판으로 전환된 특징을 갖는다.The reinforced acrylic plate for a shower booth according to the present invention is characterized in that it is converted into a reinforced acrylic plate having scratch resistance by heat treating a generally known acrylic plate.
예컨대, 도 1의 예시와 같이, 일반적인 아크릴판(10)은 표면강도는 물론 전체적인 강도가 약하기 때문에 이하 설명되는 열처리 과정을 통해 구조 강도를 높이도록 구성된다.For example, as in the example of FIG. 1, the general
본 발명에 따른 열처리 과정은 다음과 같다.The heat treatment process according to the present invention is as follows.
먼저, 아크릴판(10)을 열가마(20)에 넣고 약 150~200℃의 온도로 가열한 다음 일정시간 동안 유지한다.First, the
그러면, 상기 아크릴판(10)은 가소화되면서 연화된다.Then, the
이어, 연화된 아크릴판(10)을 하부금형(40)에 올려 놓고, 상부금형(30)을 하강시켜 가압하면서 평평하게 레벨링되도록 유지시킨다.Then, the softened
이에 따라, 아크릴판(10)의 조직은 치밀해지면서 표면강도가 급격히 상승하게 된다.As a result, the texture of the
하지만, 이러한 내용은 통상적인 강화방법과 다르지 않다. 본 발명은 이에 그치지 않고 상부금형(30)과 하부금형(40)의 각 표면, 즉 서로 마주보게 무늬판(50)이 부착된다.However, this does not differ from conventional reinforcement methods. The present invention is not limited to this, but the respective surfaces of the
이때, 주의해야 할 점은 상기 무늬판(50), 즉 상기 상부금형(30)에 부착된 무늬판(50)과, 상기 하부금형(40)에 부착된 무늬판(50)이 서로 거울대칭이어야 한다는 점이다.It should be noted that the
만약, 대칭이 되지 않게 되면 무늬가 다르거나 없는 쪽으로 냉각시 휘는 변형이 발생되어 불량품이 되기 때문이다.If it does not become symmetrical, it deforms due to cooling when the pattern is different or does not exist, which is a defective product.
즉, 상기 무늬판(50)에 의해 아크릴판(10)이 압축되면서 수평상으로 레벨링될 때 아크릴판(10)의 표면과 이면에 다수의 요철형 대칭 무늬가 동시 형성됨으로써 치밀해진 조직이 무늬를 중심으로 뭉치면서 표면강도를 높이는 효과를 얻을 수 있게 된다.That is, when the
더구나, 이러한 효과는 표면강도가 높아짐으로 인해 내스크래치성까지 증대시키는 효과를 더불어 가져오게 된다.Moreover, such an effect brings an effect of increasing the scratch resistance due to the increase of the surface strength.
이에 더하여, 본 발명은 내화성 또는 내부식성, 슬립성을 향상시키는 것은 물론 강도를 더욱 더 보강키 위해 아크릴판(10) 제조시 특정 성분이 더 첨가될 수 있다.In addition, the present invention can further improve the fire resistance or the corrosion resistance, the slip property, and the specific component in the production of the
예컨대, 본 발명에 따른 강화 아크릴판은 아크릴수지를 주성분으로 하며, 여기에 특성을 발현시키기 위한 첨가물들이 첨가되어 조성물을 이루고, 이 조성물을 재료로 하여 시트상의 아크릴판으로 제조함으로써 이루어진다.For example, the reinforced acrylic plate according to the present invention comprises an acrylic resin as a main component, and additives for expressing the properties are added to the composition to form a sheet-like acrylic plate using the composition.
이때, 본 발명에 따라 표면강도를 더욱 더 보강하기 위해 다음과 같은 보강제가 더 첨가될 수 있는데, 상기 보강제는 표면강도 뿐만 아니라, 표면에서의 이물 슬립성을 증대시켜 이물이 쉽게 부착되지 않게 함으로써 내오염성도 함께 증대시킬 수 있도록 구성된다.In this case, in order to further reinforce the surface strength according to the present invention, the following reinforcing agent may be further added. The reinforcing agent increases not only the surface strength but also the slip property on the surface, So that the pollution can also be increased.
이를 위해, 본 발명에 따른 강화 아크릴판은, 아크릴수지 100중량부에 대해, 폴리락트산 30-40중량부, 알루미나 분말 5-10중량부, 이트리아 5-10중량부, CZ(N-cyclohexylbenzothiazole-2-sulfenamide) 10-15중량부, Ds(Dichlorodimethylsilane) 8-12중량부, SB(Sodium Benzoate) 10-15중량부가 첨가된 혼합물을 충분히 교반한 후 시트상으로 성형하여 이루어진다.To this end, the reinforced acrylic plate according to the present invention comprises 30-40 parts by weight of polylactic acid, 5-10 parts by weight of alumina powder, 5-10 parts by weight of yttria, and N-cyclohexylbenzothiazole- 2-sulfenamide), 8-12 parts by weight of Ds (dichlorodimethylsilane) and 10-15 parts by weight of SB (sodium benzoate) are thoroughly stirred and molded into a sheet.
여기에서, 상기 폴리락트산은 합성고분자 타입의 수지로서 내습성, 가공성, 인장강도가 우수한 물성이 있으며, 용융온도는 150-200℃이고, 연성에 의한 연질화, 인장강도, 신장율을 향상시키는 특성이 있어 주성분인 아크릴수지의 표면이 쉽게 깨지지 않도록 강도를 향상시키는데 기여하게 된다.The polylactic acid is a synthetic polymer type resin having excellent moisture resistance, processability and tensile strength. The polylactic acid has a melting temperature of 150-200 占 폚 and has characteristics of improving softening, tensile strength and elongation by ductility Which contributes to improving the strength of the acrylic resin so that the surface of the acrylic resin as a main component is not easily broken.
이를 위해, 본 발명에서는 30-40중량부의 범위로 첨가되어야 하는데, 40중량부를 초과하게 되면 분해성이 증대되고, 30중량부 미만으로 첨가되면 인장강도를 떨어뜨리므로 상기 범위로 한정하여야 한다.In the present invention, it is added in the range of 30-40 parts by weight. When it exceeds 40 parts by weight, decomposition ability is increased. When added below 30 parts by weight, tensile strength is decreased.
또한, 상기 알루미나는 알루미늄과 산소의 화합물로서, 상기 이트리아와 결합하여 복합산화물막을 형성함으로써 강도 향상 및 내부식성 향상을 위해 사용된다.The alumina is a compound of aluminum and oxygen, and is used for improving strength and improving corrosion resistance by forming a composite oxide film by binding with yttria.
본 발명에서는 상기 알루미나와 이트리아를 1:1의 중량비로 혼합하여 첨가 사용하여야 하는데, 이 비율을 벗어나게 되면 알루미나와 이트리아의 결합성이 떨어져 복합산화물막 형성이 어렵게 되므로 강도 및 내부식성 향상을 기대할 수 없다.In the present invention, the alumina and yttria should be mixed and added in a weight ratio of 1: 1. When the ratio is out of the above range, the alumina and yttria can not be combined with each other and the composite oxide film is difficult to be formed. I can not.
특히, 상기 이트리아는 강도, 내부식성 향상 외에도 내화성을 갖고 있어 난연제로도 활용되므로 과량 첨가되면 좋겠지만, 10중량부를 넘어설 경우 아크릴판 성형시 성형성을 급격히 하락시키고 표면 평탄도를 약화시키기 때문에 상기 알루미나와 함께 10중량부 미만으로 첨가되어야 하며, 5중량부에 미달할 경우에는 내부식성 향상을 기대하기 어렵기 때문에 그 이상으로 첨가되어야 한다.Particularly, the yttria has fire resistance besides improvement in strength and corrosion resistance, and it is also used as a flame retardant, so it is desirable that it is added in an excess amount, but if it exceeds 10 parts by weight, the moldability is drastically decreased and the surface flatness is weakened It should be added in an amount of less than 10 parts by weight together with the above alumina, and if it is less than 5 parts by weight, it is difficult to expect improvement in corrosion resistance.
또한, CZ(N-cyclohexylbenzothiazole-2-sulfenamide)는 아크릴판의 표면 슬립성을 증대시켜 방오기능을 높이기 위한 것으로, 벤조티아졸 화합물로서 윤활성을 높이기 위해 10-15중량부의 범위로 첨가되어야 한다.Further, CZ (N-cyclohexylbenzothiazole-2-sulfenamide) is added to increase the surface slipperiness of the acrylic plate to improve antifouling function, and it should be added in the range of 10-15 parts by weight as a benzothiazole compound in order to enhance lubricity.
만약, 15중량부를 초과하게 되면 아크릴수지의 점도를 떨어뜨려 성형을 어렵게 하고, 10중량부 미만으로 첨가되면 윤활성이 떨어져 방오기능이 약화되므로 상기 범위로 한정하여 첨가하여야 한다.If the amount is more than 15 parts by weight, the viscosity of the acrylic resin is lowered to make the molding difficult. If the amount of the acrylic resin is less than 10 parts by weight, the lubricant may be lost and the antifouling function may be weakened.
뿐만 아니라, Ds(Dichlorodimethylsilane)도 강한 소수성을 가진 물질로서, 방오기능 향상을 위해 첨가되며, 12중량부를 초과하면 성형성을 저해하고, 8중량부 미만으로 첨가되면 뭉침현상을 유발하여 표면 평탄도를 떨어뜨리므로 상기 범위로 한정해야 한다.In addition, Ds (Dichlorodimethylsilane) also has a strong hydrophobic property and is added to improve the antifouling function. When it exceeds 12 parts by weight, moldability is inhibited. When added at less than 8 parts by weight, aggregation occurs, It should be limited to the above range.
그리고, SB(Sodium Benzoate)는 방부성을 증대시키기 위해 첨가되며, 10-15중량부 범위내로 한정하여 첨가하여야 한다.In addition, SB (sodium benzoate) is added to increase the antifogging property, and it should be added in a range of 10-15 parts by weight.
이에 더하여, 난연성 향상을 위해 난연제가 더 첨가될 수 있는데, 상기 난연제로는 실리카분말과 규산나트륨이 1:1의 중량비로 혼합된 혼합물을 20-30중량부 더 첨가할 수 있다.In addition, a flame retardant may be further added to improve the flame retardancy. As the flame retardant, 20-30 parts by weight of a mixture of silica powder and sodium silicate in a weight ratio of 1: 1 may be further added.
특히, 앞서 설명하였듯이 이트리아도 훌륭한 난연제이므로 이와 함께 난연 보강, 즉 내화성 향상을 위해 상기 혼합물이 첨가될 수 있는데, 실리카분말은 대표적인 난연, 소광제이고, 규산나트륨은 주로 물유리(Water Glass)로 알려져 있는 바, 화재 등에 의해 발열시 금속이온과 반응하여 겔화되면서 아크릴판 표면에 보호막을 형성하여 내화성이 증대되도록 작용한다.In particular, as described above, yttria is also a good flame retardant, and thus the above mixture can be added to improve flame retardancy, that is, to improve fire resistance. The silica powder is a typical flame retardant and quencher, and sodium silicate is mainly known as Water Glass Which reacts with metal ions upon heat generation due to fire or the like to form a protective film on the surface of the acrylic plate while being gelled, thereby increasing the fire resistance.
하지만, 과량 첨가되면 성형성을 떨어뜨리고, 미량 첨가되면 특성이 발현되지 않으므로 상기 범위로 한정하여 첨가됨이 특히 바람직하다.However, if it is added in an excess amount, moldability is deteriorated, and when added in a small amount, properties are not exhibited.
이러한 구성으로 이루어진 본 발명에 따른 강화 아크릴판의 특성 확인을 위해 다음과 같이 시험하였다.In order to confirm the characteristics of the reinforced acrylic plate according to the present invention having such a constitution, the following test was conducted.
[시험예][Test Example]

특히, 강도 보조제가 첨가될 경우, 더욱 더 높은 표면강도를 유지함을 확인할 수 있었다.In particular, it was confirmed that when the strength auxiliary agent is added, the surface strength is further increased.
그리고, 내스크래치성 테스트는 500원짜리 동전으로 종래재, 발명재 1,2의 표면을 긁었을 때 긁힘 자국이 나타나는지를 육안으로 확인하는 방법을 사용하였다.In the scratch resistance test, a method of visually confirming whether or not a scratch mark appears on the surface of the inventive materials 1 and 2 with a 500 won coin is used.
시험 결과, 종래재의 표면에는 선명한 긁힘 자국이 나타났지만, 발명재 1,2에서는 긁힘 자국이 나타나지 않았다.
As a result of the test, clear scratch marks appeared on the surface of conventional materials, but scratch marks did not appear on inventions 1 and 2.
(슬립성 테스트)(Slip resistance test)
슬립성을 테스트하기 위해, 종래재 및 발명재 1,2를 차량 통행이 많은 도로가에 설치하고 10일 후 외관을 관찰하여 먼지 부착정도를 확인하였으며, 확인 결과 종래재에서는 먼지 부착정도가 눈에 띌 정도로 현저하게 나타났지만, 발명재 1에서는 약간의 먼지 부착이 있었고, 발명재 2에서는 먼지 부착이 거의 없었다.
In order to test the slip property, the conventional material and the inventive materials 1 and 2 were installed on a road having a lot of vehicle traffic, and after ten days, the appearance was observed to confirm the dust adhesion degree. As a result, However, in Inventive Material 1, there was some dust adhesion, and in Inventive Material 2, there was almost no dust adhesion.
(난연성 테스트)(Flame retardancy test)
시료에 대한 난연성을 평가하기 위해 각 시편을 건축물의 내장재료 및 구조의 난연성 시험방법(KS F2271)에 따라 난연성 테스트를 하였다.In order to evaluate the flame retardancy of the specimens, each specimen was tested for flame retardancy according to the flame resistance test method (KS F2271) of the interior materials and structures of the building.
이때, 난연성 테스트시에는 발명재 2의 시편 구성시 실리카분말과 규산나트륨이 1:1의 중량비로 혼합된 혼합물을 25중량부 더 첨가하여 구성하였다.At the time of the flame retardancy test, 25 parts by weight of a mixture of silica powder and sodium silicate at a weight ratio of 1: 1 was added to the test piece of Inventive Material 2.
그 결과, 종래재와 발명재 1은 난연성이 없었고, 발명재 2의 경우에는 난연 3급에 준하는 불연성을 나타내었다.As a result, the conventional material and the inventive material 1 did not have flame retardancy, and in the case of the inventive material 2, they showed incompatibility similar to the flame retardant grade 3.
이를 통해, 본 발명에 따른 강화 아크릴판이 인체에 무해한 친환경적 도료 조성물임도 분명히 확인하였다.
Thus, it was confirmed that the reinforced acrylic plate according to the present invention is an environmentally friendly coating composition harmless to human body.
