The adhesive is an environmentally friendly binder that does not emit harmful substances to the human body, does not burn, and emits no harmful gases.
본 발명에서 사용하기에 바람직한 상기 무기계 접착제는 (i) 수산화 알루미늄분말 32 ~ 38wt%, 산화구리분말 3wt%, 산화아연분말 20 ~ 25wt%, 액상의 규산소다 41 ~ 30wt% 및 액상의 메칠 셀룰로즈 4wt%로 되는 혼합물과 (ii) 정제된 규산소다를 함유하는 것(이하 "접착제-A"라 함)이거나, 또는 여기에 (iii) 황토, 모래, 옥 및 일라이트로 이루어진 군에서 선택되는 1종 이상의 천연무기분말이 더 함유된 것(이하, '접착제-B'라 함)이다. 여기서, 상기 혼합물(i) 대 상기 규산소다(ii)의 중량비(i:ii)는 1: 8~9이고, 상기 혼합물과 상기 규산소다의 합계량(i+ii) 대 상기 천연무기분말(iii)의 중량비[(i+ii) : iii]가 1:2이다. The inorganic adhesives preferred for use in the present invention are (i) aluminum hydroxide powder 32 to 38wt%, copper oxide powder 3wt%, zinc oxide powder 20 to 25wt%, liquid sodium silicate 41 to 30wt% and liquid methyl cellulose 4wt A mixture comprising (%) refined sodium silicate (hereinafter referred to as "glue-A"), or (iii) one selected from the group consisting of ocher, sand, jade and illite The above-mentioned natural inorganic powder is further contained (hereinafter, referred to as 'glue-B'). Wherein the weight ratio (i: ii) of the mixture (i) to the sodium silicate (ii) is 1: 8 to 9, and the total amount of the mixture and the sodium silicate (i + ii) to the natural inorganic powder (iii) The weight ratio of [(i + ii): iii] is 1: 2.
상기 접착제-A는 예를 들어 수산화 알루미늄분말 32 ~ 38wt%와 산화구리분말 3wt%와 산화아연분말 20 ~ 5wt%와 액상의 규산소다 41 ~ 30wt%에 액상의 메칠 셀룰로즈 4wt%를 첨가하여 1000 rpm정도의 속도로 충분히 교반하는 단계; 상기 혼합물의 중량에 대하여 규산소다를 중량비로 8 내지 9배 첨가하여 1000rpm 내외의 속도로 1 시간 내외의 시간동안 재차 교반하여 제조할 수 있고, 상기 접착제-B는 상기한 접착제-A 성분에 천연 무기분말을 첨가하고 1000 rpm의 속도로 30 내외의 시간 동안 교반하는 것에 의해 제조할 수 있다. The adhesive-A is, for example, by adding 32 wt% to 38 wt% of aluminum hydroxide powder, 3 wt% of copper oxide powder, 20 to 5 wt% of zinc oxide powder, and 41 to 30 wt% of liquid sodium silicate, and adding 4 wt% of liquid methyl cellulose to 1000 rpm. Stirring sufficiently at a rate of about; Sodium silicate may be prepared by adding 8 to 9 times the weight ratio to the weight of the mixture and stirring again for about 1 hour at a speed of about 1000 rpm. The adhesive-B is a natural inorganic It can be prepared by adding the powder and stirring for about 30 hours at a speed of 1000 rpm.
본 발명에 있어서, 무기계 접착제의 배합비율은 조성성분들을 충분히 결합시키기에 적합한 양으로 조절하는 것이 바람직하다. 이러한 무기계 접착제의 바람직한 배합비율은 왕겨와 무기입자로 되는 주원료 100중량부에 대하여 10~20중량부가 적당하다. 무기계 접착제의 배합비율이 너무 적으면 판재의 강도가 건축용 내,외장재로 사용하기에 다소 미흡하고, 너무 많으면 판재구성성분간에 형성되는 공극이 적어져서 소망하는 통기성 및 흡음성을 달성하는 것이 어렵게 된다. In the present invention, the mixing ratio of the inorganic adhesive is preferably adjusted to an amount suitable to sufficiently bond the components. A preferred blending ratio of such an inorganic adhesive is 10 to 20 parts by weight with respect to 100 parts by weight of the main raw material consisting of chaff and inorganic particles. If the mixing ratio of the inorganic adhesive is too small, the strength of the sheet is somewhat insufficient for use as interior and exterior materials for building, and if it is too large, the gap formed in the sheet composition becomes less, making it difficult to achieve the desired breathability and sound absorption.
본 조성물에는 상기한 주원료와 무기계 접착제 이외에, 발포유리입자, 단섬유 등을 선택성분으로 배합할 수도 있다. 상기 단섬유 대용으로 일정 크기로 파쇄한 나무를 사용할 수도 있다. In addition to the above main raw materials and the inorganic adhesive, the present composition may also contain foamed glass particles, short fibers, and the like as optional components. It is also possible to use wood shredded to a certain size in place of the short fibers.
발포유리입자는 판재의 흠음성을 향상시키는 효과가 있으며 본 발명의 무기계 접착제에 대한 친화력이 높아 본 발명의 판재에 우수한 결합강도로 결합하는 특징이 있다. Foamed glass particles have the effect of improving the flaw of the plate and has a high affinity for the inorganic adhesive of the present invention has a feature of bonding to the plate of the present invention with excellent bonding strength.
발포유리(foamed glass)는 아주 미세하게 분쇄된 특수한 조성을 갖는 유리에 발포제를 혼합하여 소성한 무기질 유리로서 일반적인 명칭으로 세포성 유리(cellular glass) 또는 다세포성 유리(multicellular glass)로 불리워진다. 이러한 명칭은 이 유리가 아주 얇은 유리막으로 쌓인 세포상의 독립기공이 형성된 구조적인 특성을 지니고 있는데 기인한다. 이 발포유리는 이러한 구조적인 특성 때문에 저온보온, 불꽃차단, 단열, 방음, 내수성 등에 탁월한 효능을 나타낼 뿐 아니라 경량이어서 구조물이나 건축물에 있어 훌륭한 재료로 사용될 수 있다.Foamed glass is an inorganic glass sintered by mixing a blowing agent in a glass having a special composition that is very finely pulverized, and is generally called cellular glass or multicellular glass. This designation is due to the structural nature of the glass, which is formed by independent pores on the cells, which are stacked in a very thin glass membrane. Because of its structural properties, this foam glass not only shows excellent effects in low temperature insulation, flame protection, insulation, sound insulation, water resistance, etc., but is also lightweight and can be used as an excellent material for structures and buildings.
발포유리는 구성성분에 따라 낮은 선형열팽창 계수를 갖는 고기능성의 붕규 산 발포유리 및 소다석회 발포유리로 분류할 수 있으나 최종제품의 형태에 따라 괴상의 형태인 발포유리 벽돌(foamed glass block)과 0.1∼10mm의 직경을 갖는 구형 또는 원통형의 발포유리입자(foamed glass bead)의 두 종류로 나눌 수 있다. 발포유리 벽돌은 주로 굴뚝 및 연돌의 내장, 에틸렌 공장(ethylene plant), 액화가스의 저장탱크의 보온재 및 일반건축의 단열재로서 그 자체를 그대로 사용되고 있고 그 용도로도 점차 확대되고 있다. 그리고, 발포유리입자는 그 자체의 단독 사용보다는 시멘트와 함께 혼합하여 시멘트 벽돌 내에 또는 시멘트 구조물에 충전시킴으로써 시멘트벽돌 및 구조물의 열전도도를 낮추어 건축 및 토목 구조물의 단열 및 보온의 기능을 부여하는 것은 물론 경량화시킬 수도 있다.Foamed glass can be classified into highly functional borosilicate foamed glass and soda-lime foamed glass with low linear thermal expansion coefficient, depending on the composition, but it is a foamed glass block and 0.1 It can be divided into two types of spherical or cylindrical foamed glass beads having a diameter of ˜10 mm. Foam glass brick is mainly used as a thermal insulation material for chimneys and stacks, ethylene plant, liquefied gas storage tank and insulation of general construction, and is gradually expanding to its use. In addition, the foamed glass particles are mixed with cement rather than used alone, and filled into cement bricks or cement structures, thereby lowering the thermal conductivity of cement bricks and structures to impart thermal insulation and thermal insulation of construction and civil engineering structures. It can also reduce weight.
발포유리입자는 유리에 탄소재와 같은 환원제와 산화물, 설페이트(sulfate) 또는 다른 형태의 산화성분들을 함유하는 기포 형성제를 함께 혼합하여 이를 분쇄한 후, 이 분쇄된 혼합물을 그래인형태로 성형한 후 연화 또는 용융점까지 소성시킨다. 이 열처리 과정에서 탄소와 황산화물(또는 산화제 또는 유리의 산화물) 사이에 산화-환원반응이 일어나고 그 결과 용융된 유리는 SO2, CO2 , N2 , H2S 또는 다른 가스를 함유하게 되며, 이것이 저밀도 및 열전도 및 복사에 저항성을 갖는 구조를 형성하게 하는 물질을 만드는 유리가스를 형성한다. 그 결과 가장 최상의 결과를 얻을 경우 유리의 구조는 물 또는 수증기, 또는 다른 액체 및 기체 등이 스며들지 않는 밀폐기공을 갖게 된다. The foamed glass particles are mixed with a reducing agent such as a carbonaceous material and a bubble former containing an oxide, sulfate or other type of oxidizing component in the glass, and then pulverized, and then the pulverized mixture is formed into a grain form. It is then fired to softening or melting point. During this heat treatment, an oxidation-reduction reaction occurs between carbon and sulfur oxides (or oxidants or oxides of glass), and as a result, the molten glass contains SO 2 , CO 2 , N 2 , H 2 S or other gases. This forms a glass gas that makes a material that forms a structure that is low density and resistant to thermal conduction and radiation. As a result, for best results, the structure of the glass has a closed pore free of water, water vapor, or other liquids and gases.
본 발명에서 사용되는 발포 유리입자는 블록 등의 건축자재의 제조에 이용되 는 것으로서 이 분야에 잘 알려져 있는 것으로 폐유리 분말과 발포조제 등의 첨가제를 균일하게 혼합하고 여기에 물을 가하여 입자형태로 성형하고, 성형된 입자를 발포시키는 방법으로 제조할 수 있다. 시중구입가능한 발포유리입자의 예로는 한국미부주식회사에서 제조판매되는 인노텍스 엘더블유에이(Innotex LWA)가 있다. The foamed glass particles used in the present invention are well known in the art as used in the manufacture of building materials such as blocks, and are uniformly mixed with additives such as waste glass powder and foaming aids, and added thereto to form particles. It can be produced by molding and foaming the molded particles. An example of commercially available expanded glass particles is Innotex LWA manufactured and sold by Korea Ung Co., Ltd.
본 발명에서 사용하기에 특히 바람직한 발포유리 입자의 크기는 직경 7mm 이하, 보다 바람직하게 0.1 내지 4mm이며, 또한 발포유리입자의 압축강도와 경도는 가급적 높은 것이 바람직하다. Particularly preferred foamed glass particles for use in the present invention have a diameter of 7 mm or less, more preferably 0.1 to 4 mm, and the compressive strength and hardness of the foamed glass particles are preferably as high as possible.
본 조성물중 발포유리입자의 함량은 주원료 100중량부에 대하여 10~30 중량부가 적당하다. The content of the expanded glass particles in the composition is 10 to 30 parts by weight based on 100 parts by weight of the main raw material.
단섬유, 예를 들어 전연 또는 합성 단섬유는 판재의 탄성, 내충격성 등의 물성을 향상시키는 효과가 있으며, 본 조성물중 발포유리입자의 함량은 주원료 100중량부에 대하여 0.1~10 중량부가 적당하다. 단섬유의 배합비가 너무 낮으면 너무 높으면 다른 조성성분과의 균질한 혼합이 어려워 균일한 물성분포를 갖는 판재를 얻는 것이 곤란하게 된다. Short fibers, for example, leading edge or synthetic short fibers have the effect of improving the physical properties such as elasticity, impact resistance, etc. of the plate, the content of the foam glass particles in the composition is suitable 0.1 to 10 parts by weight based on 100 parts by weight of the main raw material. . If the blending ratio of the short fibers is too low, it is difficult to homogeneously mix with other composition components, it is difficult to obtain a plate having a uniform water component cloth.
본 발명에 따르는 판재는 예를 들어 설명하면 왕겨와 무기입자 그리고 상기 무기계 접착제를 배합하고, 선택성분으로서 발포유리입자, 단섬유 등을 배합하고, 혼합하여 이를 통상의 연속식 또는 비연속식 판재성형방법으로 제조할 수 있다. For example, the plate according to the present invention may be blended with chaff, inorganic particles, and the inorganic adhesive, and as an optional component, foamed glass particles, short fibers, and the like may be mixed and mixed to form a conventional continuous or discontinuous plate. It can manufacture by a method.
예를 들어 비연속식 판재 성형에는 소정형상의 성형틀에 혼련된 조성물을 충전하여 프레스 성형하는 방법이 있으며, 연속식 판재 성형에는 혼련된 조성물을 상 하 한쌍의 롤로 이루어진 프레스 롤러군을 통과시켜 소정의 두께로 압출하고 압출된 연속상의 판재를 소정의 크기로 절단하여 성형하는 방법이 있다. For example, there is a method of forming a non-continuous plate by pressing a composition kneaded in a mold of a predetermined shape to press molding, and in the case of continuous plate forming, the kneaded composition is passed through a press roller group consisting of a pair of upper and lower rolls. There is a method of extruding to a thickness of and cutting the extruded continuous plate to a predetermined size to form.
본 발명의 판재는 그 자체로 건축내외장제로 이용할 수도 있으나, 부직포 또는 견면을 판재의 일면 또는 양면에 적층하여 사용할 수도 있고, 또한 MDF 패널과 같이 무늬목 등과 같은 시트를 판재의 일면 또는 양면에 적층하여 사용할 수도 있다. The plate of the present invention may be used as a building interior and exterior agent itself, but may be used by laminating a nonwoven fabric or a plush on one or both sides of the plate, and also by laminating a sheet such as veneer on one or both sides of the plate such as an MDF panel. Can also be used.

[실시예 1]Example 1
수산화 알미늄(60~300mesh) 35중량%, 액상 규산소다 35중량%, 산화구리(60 ~ 300 mesh) 3중량%, 산화아연(60 ~ 300 mesh) 23중량%, 메칠셀룰로즈(평균분자량 17,000이하) 4중량%의 비율로 혼합된 A재료를 1000rpm 정도의 교반속도로 충분히 교반한 후 정제된 규산소다를 재차 투입하여 기본재료를 완성한다. 기본재료를 완성하기 위한 규산소다의 투입비율은 A재료에 대하여 중량비로 규산소다를 8 내지 9배가 되도록 혼합하였다. 이때에도 1000 rpm 정도의 교반속도로 일반 상온에서 약 1시간 내외의 시간동안 충분히 교반시켜 무기계 접착제를 제조하였다. 35% by weight of aluminum hydroxide (60-300mesh), 35% by weight of liquid sodium silicate, 3% by weight of copper oxide (60-300 mesh), 23% by weight of zinc oxide (60-300 mesh), methyl cellulose (average molecular weight 17,000 or less) The A material mixed at a ratio of 4% by weight is sufficiently stirred at a stirring speed of about 1000 rpm, and then purified sodium silicate is added again to complete the basic material. The input ratio of sodium silicate to complete the base material was mixed so that the sodium silicate was 8 to 9 times by weight relative to the material A. In this case, the inorganic adhesive was prepared by sufficiently stirring for about 1 hour at normal room temperature at a stirring speed of about 1000 rpm.
제조된 무기계 접착제 30kg, 질석입자 또는 페라이트입자 120kg 및 폭쇄한 왕겨 180kg의 비율로 균일하게 혼합하여 얻어진 혼합물을 한쌍의 롤로 이루어지고 하류로 갈수록 닙간격이 점점 좁이지는 다단의 프레스 롤러를 통과시켜 915mm× 1830mm의 판재를 제조하였다. 제조된 판재를 동일한 사이즈의 기존의 MDF 판재, 석고보드, NF/시멘트 보드와 특성을 비교하였다. 그 결과는 표 1에 제시된다.The mixture obtained by uniformly mixing at a ratio of 30 kg of the inorganic adhesive prepared, 120 kg of vermiculite or ferrite particles, and 180 kg of crushed rice hulls was composed of a pair of rolls and passed through a multi-stage press roller whose nip spacing gradually narrowed downstream. A plate of 1830 mm was manufactured. The prepared plate was compared with the conventional MDF plate, gypsum board, and NF / cement board of the same size. The results are shown in Table 1.
