Description

분말 방수제{POWDERED WATER PROOFING AGENT}Powder waterproofing agent {POWDERED WATER PROOFING AGENT}

본 발명은 분말 형태의 방수제에 대한 것으로서, 특히, 벽돌 표면에 타설이 가능한 분말 방수제로서, 높은 침투력과 방수력을 갖는 방수제를 낮은 단가로 제조될 수 있는 것이다. The present invention relates to a waterproofing agent in the form of a powder, and in particular, as a waterproofing agent capable of being cast on a brick surface, a waterproofing agent having high penetration and waterproofing power can be manufactured at a low cost.

일반적으로, 방수제(防水劑, waterproof agent)는, 방수성(防水性)을 갖게 하기 위하여 사용되는 재료를 말하는 것으로, 방수포(防水布)와 같이 무명, 삼베의 발에 아스팔트 등을 함침(含浸)시킨 것, 또는 콘크리트블록 등의 아스팔트루핑이나, 모르타르, 콘크리트제품 등의 표면, 또는 천/종이/섬유제품의 표면에 발라서 발수성(撥水性: 물이 겉돌게 하는 성질)을 갖게 하는 것, 또한 모르타르 ·콘크리트의 혼합, 용해제로서 방수성과 수밀성을 증대시키는 것 등 다양하다. In general, a waterproof agent refers to a material used to make it waterproof, and is made of cotton, such as a waterproof cloth, impregnated with asphalt, etc. on the feet of hemp. It is applied to the asphalt roofing of concrete blocks, the surface of mortar, concrete products, or the surface of cloth/paper/fiber products to give water repellency (water repellency), and mortar It is various such as mixing concrete and improving watertightness and waterproofness as a dissolving agent.

상기 방수제 중에서, 콘크리트 제품, 콘크리트 구조물에 사용하는 일반적인 방수제는, 다양한 유기질 및 유기질 및 화학적 성분이 포함되어, 도포한 모재 표면에 방수층을 형성하여 콘크리트층에 방수 효과를 갖도록 적용된다.Among the waterproofing agents, general waterproofing agents used for concrete products and concrete structures are applied to have a waterproof effect on the concrete layer by forming a waterproof layer on the surface of the coated base material by containing various organic, organic, and chemical components.

또한, 최근에는 무기질 또는 무기계 재료를 주성분으로 하는 방수제가 제시되고 있는바 그 예시를 들면 대한민국 특허등록 제474166호 '세라믹 방수방법 및 그에 사용되는 방수제' 특허기술에서는 40％의 옥 파우더, 20％의 규사, 30％의 포틀랜드 시멘트, 3％의 메틸셀로우즈 및 7％의 옥사이드로 구성되는 무기질 재료와 20％의 S.B.R 라텍스, 20％의 E.V.A 접합제, 3％의 소디움 벤조나이트, 57％의 증류수로 구성되는 경화재가 혼합되도록 적용되는 방수제가 제시되어 있다.In addition, recently, a waterproofing agent containing inorganic or inorganic materials as a main component has been proposed. For example, Korean Patent Registration No. 474166'Ceramic waterproofing method and waterproofing agent used therein' patent technology has 40% of jade powder and 20% of waterproofing agent. Inorganic material composed of silica sand, 30% Portland cement, 3% methyl cellulose and 7% oxide, 20% SBR latex, 20% EVA bonding agent, 3% sodium benzoite, 57% distilled water A waterproofing agent applied so that the hardening material composed of is mixed is suggested.

또한, 대한민국 특허등록 제668077호 '콘크리트 및 이를 이용한 콘크리트 구조물 보호용 무기계 표면침투제'는 부분적으로 가수분해되어 조절된 에틸실리케이트 단량체 50 내올리고머 실록산 및 저분자량의 폴리실록산으로 이루어진 군에서 선택된 어느 하나의 유기계 실리콘 화합물 10 내지 50중량％로 이루어진 조성 100 중량부에 대하여 글라이콜 에테르계, 탄화수소계, 글리콜 에테르 에스테르계 및 C1∼C4의 알코올로 이루어진 군에서 선택된 어느 하나의 유기용매 10 내지 50중량부로 구성하는 표면침투제가 제시되어 있고, 최근 토목분야를 중심으로 도포방수제라 칭하는 구체방수제(軀體防水濟)의 수요가 증가하고 있다. In addition, Republic of Korea Patent Registration No. 668077'Inorganic surface penetrant for protecting concrete and concrete structures using the same' is partially hydrolyzed to control ethyl silicate monomer 50 oligomer siloxane and low molecular weight polysiloxane selected from the group consisting of any one organic silicone Consisting of 10 to 50 parts by weight of any one organic solvent selected from the group consisting of glycol ethers, hydrocarbons, glycol ether esters and C1 to C4 alcohols based on 100 parts by weight of the composition consisting of 10 to 50% by weight of the compound Surface penetrants have been suggested, and demand for concrete waterproofing agents called coating waterproofing agents is increasing in the field of civil engineering in recent years.

이러한 방수제는 콘크리트면에 타설하여 구체(驅體)에 무기질 분말이 도포되도록 하는 것이나, 상하방향으로도 높은 압력을 받는 벽돌 표면에 타설하기에는 방수 효과가 현저히 떨어지는 문제가 있다. Such a waterproofing agent is poured on a concrete surface so that inorganic powder is applied to a sphere, but there is a problem in that the waterproofing effect is significantly lowered when it is placed on a brick surface that is subjected to high pressure in the vertical direction as well.

일반적으로 콘크리트 방수제로 유기질 재료는 표면에 단순히 유기성 방수막을 형성하기 때문에 시간이 지남에 따라 부착력과 내구성이 떨어지고, 내산성이 떨어지며 유기 용재에 취약한 문제점이 있고 자외선에 직접적인 노출시 부착성과 내구성이 더욱 떨어지는 문제점이 있고, 무기계 재료를 주성분으로 하는 분말형 도포제 또는 방수제는 접착성능 등의 물성을 향상시킬 필요성이 요구되어 왔다.In general, as a concrete waterproofing agent, organic materials simply form an organic waterproofing film on the surface, so adhesion and durability decrease over time, acid resistance decreases, and are vulnerable to organic solvents, and when direct exposure to ultraviolet rays, adhesion and durability decrease further. In addition, there has been a need for a powder coating agent or waterproofing agent containing an inorganic material as a main component to improve physical properties such as adhesion performance.

본 발명은 제조 단가가 낮으면서, 쉽게 제조가 가능하며 방수 효과를 크게 향상시킬 수 있는 분말 방수제를 제안하고자 한다. An object of the present invention is to propose a powder waterproofing agent that can be manufactured easily while having a low manufacturing cost and greatly improves the waterproofing effect.

본 발명에 따른 분말 방수제는, 점토를 원료로 하는 벽돌 표면에 타설될 수 있는 방수제로서, 75wt%의 양으로 첨가되는 포틀랜드 시멘트와, 20wt%의 양으로 첨가되는 쿼츠 샌드와, 첨가제로서, 1wt% 양으로 첨가되고, 다당류 생체 고분자인 검분말과, 첨가제로서, 1wt%의 양으로 첨가되고, 습윤제의 역할을 수행하는 하이드록시프로필 메틸셀룰로스(Hydroxypropyl methylcellulose, HPMC)와, 첨가제로서, 1wt%의 양으로 첨가되는 칼슘실리케이트와, 첨가제로서, 1wt%의 양으로 첨가되고, 분자식이 Na2OSiO2**5H2O 또는 Na2OSiO2*9H2O인 소듐 실리케이트와, 첨가제로서, 1wt%의 양으로 첨가되는 이산화규소를 포함하는 것을 특징으로 한다. The powder waterproofing agent according to the present invention is a waterproofing agent that can be poured on the surface of a brick made of clay as a raw material, Portland cement added in an amount of 75 wt%, quartz sand added in an amount of 20 wt%, and as an additive, 1 wt% Gum powder, which is a polysaccharide biopolymer, is added in an amount, and as an additive, hydroxypropyl methylcellulose (HPMC) is added in an amount of 1 wt% and serves as a wetting agent, and as an additive, in an amount of 1 wt% Calcium silicate added as an additive, sodium silicate having a molecular formula of Na 2 OSiO 2 * *5H 2 O or Na 2 OSiO 2 *9H 2 O, and an amount of 1 wt% as an additive It characterized in that it comprises silicon dioxide added as.

제안되는 바와 같은 본 발명의 분말 방수제에 의해서, 제조 단가가 낮으면서 방수의 효율을 증가시킬 수 있으며, 단열 효과와 소음방지 효과 뿐만 아니라 포틀랜트 시멘트의 수성 현탁액에 결정을 안정화시킬 수 있는 장점이 있다. By the powder waterproofing agent of the present invention as proposed, it is possible to increase the efficiency of waterproofing while having a low manufacturing cost, and has the advantage of stabilizing the crystals in the aqueous suspension of Portland cement as well as the insulation effect and noise prevention effect. .

이하, 본 발명의 바람직한 실시예에 대한 분말 방수제에 대해서 상세히 설명한다. Hereinafter, a powder waterproofing agent for a preferred embodiment of the present invention will be described in detail.

먼저, 본 발명에 따른 분말 방수제는 벽돌 제조 공장이나 건축 현장에서 점토를 주원료로 하는 벽돌 표면에 타설되는 분말 방수제에 대한 것이다. First, the powder waterproofing agent according to the present invention is for a powder waterproofing agent that is poured on the surface of a brick using clay as a main raw material in a brick manufacturing factory or a construction site.

본 발명의 방수제를 주로 구성하는 포틀랜드 시멘트는 주성분이 석회, 실리카, 알루미나 및 산화철을 함유하는 원료를 혼합한 것으로서, 그 일부가 용융하여 소결된 클링커에 석고를 첨가해 분말로 이루어진 것이다. 본 발명의 방수제는 주택이나 건물 건축시 사용되는 벽돌에 사용되도록 하기 위한 것으로, 벽돌 제조 공장에서 방수제를 도포하여 출하하거나, 건축 현장에서 직접 방수제를 벽돌에 도포시킬 수 있다. Portland cement, which mainly constitutes the waterproofing agent of the present invention, is a mixture of raw materials containing lime, silica, alumina, and iron oxide as the main components, and is made of powder by adding gypsum to the clinker that is partially melted and sintered. The waterproofing agent of the present invention is intended to be used for bricks used in the construction of houses or buildings, and may be shipped by applying a waterproofing agent in a brick manufacturing factory, or the waterproofing agent may be applied directly to the bricks at a construction site.

방수제의 원가를 절감시키면서 현장에서도 쉽게 제조할 수 있도록 하기 위하여 포틀랜드 시멘트가 주성분으로 이루어진다. Portland cement is the main component in order to reduce the cost of the waterproofing agent and make it easier to manufacture on site.

상기 포틀랜드 시멘트를 주성분으로 하여 쿼츠 샌드(Quartz sand, 규사)가 부성분으로 포함되며, 첨가제로는 분산 검분말, 하이드록시프로필 메틸셀룰로스, 칼슘 실리케이트, 소듐 실리케이트, 및 이산화규소가 포함된다. The Portland cement is used as a main component, and quartz sand is included as an auxiliary component, and additives include dispersed gum powder, hydroxypropyl methylcellulose, calcium silicate, sodium silicate, and silicon dioxide.

상기 쿼츠 샌드는 포틀랜드 시멘트가 70wt%의 양만큼 사용되는 때에 20wt%의 양이 혼합된다. The quartz sand is mixed in an amount of 20 wt% when Portland cement is used in an amount of 70 wt%.

상기 쿼츠 샌드는 세립자가 많으면 상기 포틀랜드 시멘트의 유동성이 증가하지만 크기에 따라 유동성, 펌핑성, 공기연행성에 영향을 미치므로 인위적으로 부순 고른 입도를 가져 품질을 향상시킬 수 있는 직경 약 200메쉬 이하의 쿼츠 샌드를 사용하는 것이 좋다. 쿼츠샌드의 직경이 200메쉬보다 더 작은 것이 사용되는 것도 가능하지만, 벽돌 표면에 타설되는 방수제에 대한 것이기 때문에 100메쉬 내지 200 메쉬 범위의 크기면 충분하다. The quartz sand increases the fluidity of the Portland cement when there are many fine particles, but it affects the fluidity, pumpability, and air entrainment depending on the size. It is better to use sand. It is possible to use a quartz sand with a diameter of less than 200 mesh, but a size in the range of 100 mesh to 200 mesh is sufficient because it is for a waterproofing agent poured on the brick surface.

또한, 상기 포틀랜드 시멘트가 75wt%의 양이 첨가될 때, 1wt% 양으로 분산 검분말(dispersible gum powder)가 혼합된다. 예를 들어, 분산 검분말은 다당류 생체 고분자로서 유체를 점성화하기 위하여 제작된 것이다. 담수, 해수, 소금 및 염수 모두에 용해되며, 잔탄 검(Xanthan Gum)이 사용될 수 있다. In addition, when the Portland cement is added in an amount of 75 wt%, dispersible gum powder is mixed in an amount of 1 wt%. For example, the dispersed gum powder is a polysaccharide biopolymer, which is manufactured to make a fluid viscous. It is soluble in both fresh water, sea water, salt and brine, and Xanthan Gum can be used.

잔탄 검은 다당체이며, 글루코스, 수 크로스 또는 락토오스의 발효에 의해 생성되는 클루코오스, 만노스 및 글루 쿠 론산을 2:2:1의 몰비로 포함하는 펜타사카라이드 반복 단위로 구성된다. Xanthan gum is a polysaccharide and is composed of pentasaccharide repeating units containing glucose, mannose, and glucuronic acid in a molar ratio of 2:2:1, produced by fermentation of glucose, sucrose or lactose.

특히, 상기 잔탄 검은 본 발명의 방수제에서 점도 및 겔 구조를 형성하며, 1 wt.%의 비율만으로도 효과적인 전단 박리 작용은 높은 전단하에서의 침투율을 증가시킬 수 있다. In particular, the xanthan gum forms a viscosity and a gel structure in the waterproofing agent of the present invention, and an effective shear peeling action with only a ratio of 1 wt.% can increase the penetration rate under high shear.

잔탄 검의 경우, 상온(예를 들면, 20℃)에서 물과 소금물에 매우 잘 용해되기 때문에, 일반적인 벽돌 제조 공장이나 건축 현장에서도 방수제 제조를 위해 사용될 수 있다. In the case of xanthan gum, since it is very soluble in water and salt water at room temperature (for example, 20°C), it can be used for the manufacture of waterproofing agents in general brick manufacturing plants or construction sites.

상기 분산 검분말이 제조되는 분말 방수제에서 1wt%를 초과하게 되는 경우에는, 제조되는 분말 방수제를 벽돌 표면에 타설할 때에 그 점성이 너무 높아져 현장에서 벽돌에 도포/코팅을 하기 매우 어려워지므로, 포틀랜드 시멘트가 75wt%의 양이 사용되는 경우에는 1/75에 해당하는 1wt%로 혼합되는 것이 가장 바람지하다. If the dispersed gum powder exceeds 1 wt% in the powder waterproofing agent to be manufactured, the viscosity of the manufactured powder waterproofing agent is too high when the manufactured powder waterproofing agent is poured onto the brick surface, making it very difficult to apply/coating to the brick at the site, so Portland Cement When the amount of 75wt% is used, it is most preferable to mix it with 1wt% corresponding to 1/75.

또한, 본 발명에서 포틀랜드 시멘트가 75wt%의 양이 사용되면, 습윤제의 역할을 수행하는 하이드록시프로필 메틸셀룰로스(Hydroxypropyl methylcellulose, HPMC)는 1wt%의 양이 첨가된다. In addition, in the present invention, when an amount of Portland cement is used in an amount of 75 wt%, hydroxypropyl methylcellulose (HPMC) serving as a wetting agent is added in an amount of 1 wt%.

상기 하이드록시프로필 메틸셀룰로스(Hydroxypropyl methylcellulose, HPMC)는 서방성 약물 제제화시 친수성 매트릭스의 제조 및 고체 화합물의 고체 분산물 내 습윤제 및 담체로서의 기능을 비롯하여, 제약 산업에서 다양한 방식으로 이용된다. 본 발명에서는 하이드록시프로필 메틸셀룰로스를 방수제의 1 wt%의 비율로 혼합되며, 결정 안정화제 및 습윤제로서의 역할을 수행한다. 포틀랜트 시멘트의 수성 현탁액에 결정을 안정화시키고, 결정 성장 및 재형성을 제어함으로써 결정 구조를 안정화할 수 있다. 하이드록시프로필 메틸셀룰로스는 본 발명의 방수제에서 습윤제로도 작용할 수 있다. 포틀랜드 시멘트와 석영의 수성 현탁액에 하이드록시프로필 메틸셀룰로스를 첨가하게 되면 현탁된 포틀랜드 시멘트와 석영 결정의 크기 변화, 용해 및 재결정화가 현저히 느려진다. The hydroxypropyl methylcellulose (HPMC) is used in a variety of ways in the pharmaceutical industry, including the preparation of a hydrophilic matrix and a function as a wetting agent and a carrier in a solid dispersion of a solid compound when formulating a sustained-release drug. In the present invention, hydroxypropyl methylcellulose is mixed in an amount of 1 wt% of the waterproofing agent, and serves as a crystal stabilizer and a wetting agent. The crystal structure can be stabilized by stabilizing the crystals in an aqueous suspension of Portland cement and controlling crystal growth and reformation. Hydroxypropyl methylcellulose can also act as a wetting agent in the waterproofing agent of the present invention. The addition of hydroxypropyl methylcellulose to the aqueous suspension of Portland cement and quartz significantly slows the size change, dissolution and recrystallization of the suspended Portland cement and quartz crystals.

또한, 첨가제로서 방수제의 단열 효과와 소음방지 효과를 증가시키기 위하여 칼슘 실리케이트(calcium silicate)가 1wt%의 양만큼 첨가된다. 1wt% 이하의 양이 사용되면 되지만, 1wt%를 초과하게 되면 단열 효과가 크게 증가하지는 않으면서 고가의 중공체 분말이 고다 사용됨에 따라 제조 단가가 크게 증가하기 때문에, 1wt% 정도의 양만큼 첨가되면 충분하다. In addition, as an additive, calcium silicate is added in an amount of 1 wt% in order to increase the insulation effect and noise prevention effect of the waterproofing agent. An amount of 1 wt% or less may be used, but if it exceeds 1 wt%, the insulation effect does not increase significantly, and the manufacturing cost increases significantly as expensive hollow powders are used extensively.If the amount is added in an amount of about 1 wt%, Suffice.

또한, 첨가제로서 소듐실리케이트(sodium silicate)가 1wt%의 양만큼 첨가된다. 상기 소듐실리케이트는 분자식이 Na2OSiO2**5H2O 또는 Na2OSiO2*9H2O로서, 백색 립상으로 물에 가용 침투력이 강하다. 상기 소듐실리케이트는 정제수(물)에 쉽게 용해되는 성질을 갖고 있으며, 별다른 온도조건이나 별도의 장치를 사용하지 않고서도 제조할 수 있다. In addition, as an additive, sodium silicate is added in an amount of 1 wt%. The sodium silicate has a molecular formula of Na 2 OSiO 2* *5H 2 O or Na 2 OSiO 2 *9H 2 O, and has a strong soluble permeability in water in the form of white granules. The sodium silicate has a property that is easily soluble in purified water (water), and can be prepared without using a special temperature condition or a separate device.

또한, 첨가제로서 이산화규소(silicon dioxide)가 1wt%의 양만큼 첨가되며, 규소의 산화물로 실리카라고도 하며, 습기를 잡아주는 흡습 작용의 기능이 있다. 이산화규소는 분말 방수제를 벽돌표면에 타설할 때에 이산화규소가 물에 반응하여 실리카가 형성된 후 겔로 변하는 과정에서 벽돌 내부의 열과 수분에 의해 침투가 이루어져 겔화를 마치게 되면 벽돌 피복 내부를 채워주게 되고, 산성비, 미세먼지, 물 등을 방지해주면서 열화를 억제하고 벽돌 표면을 추가적으로 도색으로 마감할 수 있도록 해준다. In addition, silicon dioxide is added in an amount of 1 wt% as an additive, and it is also referred to as silica as an oxide of silicon, and has a function of absorbing moisture. When the powder waterproofing agent is poured on the brick surface, silicon dioxide reacts with water to form silica and then becomes a gel. In the process, it penetrates by heat and moisture inside the brick, and when gelation is complete, it fills the inside of the brick covering. It suppresses deterioration while preventing fine dust, water, etc., and allows the brick surface to be additionally painted.
