Abstract
Description
본 발명은 방수성이 우수하며 동시에 시멘트 및 콘크리트 제품이나 구조물의 물리적 특성을 향상시킬 수 있는 방수제의 제조방법에 관한 것이다.The present invention relates to a method for producing a waterproofing agent that can improve the physical properties of the cement and concrete products or structures at the same time excellent waterproof.
시멘트 제품이나 콘크리트 구조물에 요구되는 특성중 특히 방수성 및 물리적 강도를 충족 시키기 위해서는 여러가지 방법과 수단이 채택되고 있다. 예를 들면 조직치밀화에 의한 방수성 및 물리적 강도를 향상 시키기 위해서 진동법, 원심법등의 기계적인 수단도 사용할 수 있고, 경화 후에 발생되는 유리석회의 생성을 방지하기 위해서 유리석회와 반응하는 물질을 첨가하여 이와 같은 반응물이 시멘트 입자와 입자간의 간극에 침적하여 견고히 고착하므로서 수밀성과 강도를 향상시키는 반응물의 첨가법이 있으며 유화능과 분산능을 가진 물질을 사용하여 물의 표면장력을 감소시키고 내부입자들의 마찰력을 적게하여 골재를 더욱 습윤하게 해주므로서 양생을 균일하게 할 수 있고 수분요구량을 적게 하여 경화 건조 후 물이 차지하는 용적을 줄일 수 있어 결국 치밀한 조직을 가질 수 있게 하는 방법이라 할 수 있다.Various methods and measures have been adopted to meet the properties required for cement products and concrete structures, especially waterproofness and physical strength. For example, mechanical means such as vibration and centrifugal methods can also be used to improve the waterproofness and physical strength due to densification of the tissues. There is a method of adding a reactant to improve the watertightness and strength by depositing the reactant in the gap between the cement particles and particles, and to reduce the surface tension of water and frictional force of the internal particles by using a material having emulsification capacity and dispersibility It can be called a method to make the aggregate more wet, so that the curing can be made uniform, and the moisture demand can be reduced to reduce the volume of water after curing and drying, thus allowing a dense structure.
그 밖에도 몰탈시공시 기포를 억제하는 방법도 방수능과 물리적 강도를 높이는 기여할 수 있는 하나의 수단이라 하겠다. 종래 한국 특허공고 79-621호는 스테아린산과 소석회, 염화칼슘을 반응시켜 얻은 액에 리그닌술폰산 나트륨을 배합 한 것이 있으나 백화현상과 그에 따른 방수성저하, 작업성, 강도등에 있어서 좋지않은 점이 있었다.In addition, the method of suppressing bubbles during mortar construction is one means that can contribute to increase the waterproof performance and physical strength. Previously, Korean Patent Publication No. 79-621 had a mixture of sodium lignin sulfonate in a solution obtained by reacting stearic acid with hydrated lime and calcium chloride, but there was a disadvantage in whitening phenomenon and its waterproofing, workability and strength.
이와 같이 방수성과 물리적 강도를 향상시키기 위해서는 전술한 조건들을 충족시키지 않고서는 우수한 방수능과 동시에 강도를 보유하기 힘들다, 그러나 종래 방수제의 대부분은 전술한 조건들의 일부를 충족시킴에 불과하다.As such, in order to improve the waterproofness and physical strength, it is difficult to have excellent waterproofing performance and strength at the same time without satisfying the above-mentioned conditions, but most of the conventional waterproofing agents only satisfy some of the above-described conditions.
예를 들어 아스팔트, 핏치, 파라핀등 유기 고분자 물질을 주재로 한 방수제는 방수성은 좋으나 비 수화성 물질로서 이들이 시멘트 입자들 둘러 싸거나 입자와 입자사이에 끼어들어 수화작용을 방해하므로서 시멘트 입자간에 수경화에 의하여 발생하는 강도를 저하시킨다. 또 지방산 금속염을 주재로한 유화능과 분산능을 향상시킨 방수제는 작업성을 좋게하고 수경성을 향상 시킬 수 있으며 수화에 요하는 물의 양을 줄일 수 있어 조직 치밀화를 도모할 수 있으나 시공 후 유리석회의 생성을 방지함에는 도움이 되지 못한다. 그밖에도 종래 방수제의 일부 성분으로 수용성 물질이 포함되어 결화건조 후에도 수분을 흡수하면 용해되어 용출되므로서 방수능을 크게 저하시킨다. 본 발명은 종래 방수제의 부족한 기능을 보완하여 방수성 강도 및 내후성을 크게 보강한 방수제로서 이의 제법을 설명하면 다음과 같다.For example, waterproofing agents based on organic polymers such as asphalt, pitch, and paraffin have good water resistance, but are non-hydratable materials, which are hardened between cement particles by enclosing the cement particles or interfering between particles and preventing hydration. Decreases the strength generated. In addition, the waterproofing agent which improves the emulsification capacity and dispersibility mainly based on fatty acid metal salt can improve workability, improve hydraulic properties, and can reduce the amount of water required for hydration, so that tissue compaction can be achieved. It does not help to prevent creation. In addition, some components of the conventional waterproofing agent contains a water-soluble substance and absorbs moisture even after condensation drying, thereby dissolving and eluting, thereby greatly reducing the waterproofing performance. The present invention will be described below as a waterproofing agent that greatly enhances the waterproofing strength and weather resistance by supplementing the insufficient function of the conventional waterproofing agent.
본 발명에 의한 방수제의 제조방법은 먼저 스테아린산과 암모니아수를 반응시키고 여기에 황산알미늄을 첨가하여 약 120℃-130℃에서 재차 반응시킨다음 이 반응물에 리그닌술폰산칼슘 수용액을 첨가 분산시킴을 특징으로 하는 방수제의 제조 방법에 관한 것이라 하겠다.The method for preparing a waterproofing agent according to the present invention comprises first reacting stearic acid with ammonia water and adding aluminum sulfate thereto to react again at about 120 ° C.-130 ° C., and then dispersing an aqueous solution of calcium lignin sulfonate in the reactant. It relates to the manufacturing method of.
이의 반응에서 제1단계 반응은 스테아린산과 암모니아수가 반응하여 스테아린산암모늄을 생성하고 여분의 스테아린산과 황산알미늄이 반응하여 스테아린산 알미늄이 생성된다.In the reaction, stearic acid and ammonia water react to form ammonium stearate, and excess stearic acid and aluminum sulfate react to produce aluminum stearate.
여기에서 스테아린산은 암모니아수 반응할 수 있는 양외에 황산알미늄과 반응할 수 있는 여분의 양이 투입되고 황산알미늄도 약간 과량으로 분산유화된 상태로 존재하는 것이 유리하다.In this case, stearic acid is added in an amount that can react with aluminum sulfate in addition to the amount capable of reacting with ammonia water, and it is advantageous that the aluminum sulfate is also present in a slightly excessively dispersed emulsion state.
이의 반응에서 소요되는 원료 투입량은 엄격하게 제한되는 것은 아니지만 대략 중량비로 오레인산 100부에 대하여 10%의 암모니아수 15-30부, 황산알미늄 5-10부, 리그닌술폰산칼슘 5-20부를 사용하고 리그닌술폰산의 경우에는 적량의 물에 분산시킨 상태에서 사용된다.The input amount of raw materials required in the reaction is not strictly limited, but the weight ratio is about 15 parts by weight of 10% ammonia water, 5-10 parts of aluminum sulfate, 5-20 parts of calcium sulfate and 5-20 parts of lignin sulfonic acid, based on 100 parts of oleic acid. In the case of, it is used in a state dispersed in a suitable amount of water.
또 본발명에 의하여 제조된 방수제의 몰탈시공 및 강화건조 후의 작용과 기능을 살펴보면 반응생성물인 스테아린산알미늄은 윤활성과 분산성이 양호하여 몰탈시공시 균일한 배합과 작업성을 크게 향상시키므로서 수경화에 필요한 물의 양을 줄일 수 있으므로 시멘트입자와 입자간에 스테아린산알미늄입자가 층진되고 시멘트나 콘크리트의 겉보기 체적을 줄일 수 있어 수밀성을 좋게하고 나아가서 기포발생을 억제하는 작용도 있으므로 우수한 방수능과 강도를 부여하는 작용을 가진다. 또 스테아린산 암모늄도 윤활성과 분산성이 양호하여 콘크리트 방수능제의 기능을 가지고 있으며 미반응 황산알미늄은 수산화석회와 반응하여 황산칼슘을 생성하므로서 유리석회의 생성을 방지할 수 있다.In addition, the action and function after the mortar and reinforcement drying of the waterproofing agent prepared according to the present invention show that the reaction product, aluminum stearate, has good lubricity and dispersibility, and greatly improves the uniform mixing and workability during mortar application. Since the amount of water required can be reduced, aluminum stearate particles are stratified between the cement particles and the particles, and the apparent volume of cement or concrete can be reduced to improve water-tightness and further suppress bubbles. Has In addition, ammonium stearate also has good lubricity and dispersibility and has the function of a concrete waterproofing agent. Unreacted aluminum sulfate reacts with lime hydroxide to produce calcium sulfate, thereby preventing the formation of free lime.
그 밖에 라그닌술폰산칼슘은 그 구성단위가 방향고리에 수산기(OH), 메톡실기(-CH3O)등의 치환기를 갖는 화학구조이여서 분산능이 우수하며 몰탈시공시 작업성을 향상시킬수 있고 균일한 배합이 가능하며 수경화에 필요한 수량을 줄일 수 있으므로서 방수기능을 가지며 용액상태에서도 안정성이 있어 방수액중에서 다른 물질을 균일한 분산 상태의 용액으로 장기간 보존할 수 있다.In addition, calcium ragnin sulfonate is a chemical structure having a substituent such as hydroxyl group (OH), methoxyl group (-CH 3 O) in the aromatic ring, excellent dispersibility and improved workability during mortar construction and uniformity It is possible to mix and reduce the amount of water needed for water curing, and it has waterproof function, and it is stable even in solution state, so that other materials can be stored in the solution in a uniform dispersion state for a long time.
지금까지 본 발명에 의한 방수제의 개괄적인 제조 방법과 이에 대한 이론적인 설명을 기술했지만 구체적인 실시예를 들므로서 본 발병에 대한 기술사상을 더욱 분명하게 할 수 있다.Although the general manufacturing method of the waterproofing agent by this invention and the theoretical explanation for this have been described so far, the technical concept of this disease can be clarified by listening to a specific example.
