Description

색상 시멘트 건축재용 변색 방지제Discoloration inhibitors for color cement building materials

본 발명은 몰탈, 큰크리트 등, 시멘트를 주재로 하여서 되는 색상 시멘트 건축재에, 내변색성을 부여하는 첨가물을 조성하는 변색 방지제에 관한 것이다.The present invention relates to a discoloration preventing agent for forming an additive for imparting discoloration resistance to color cement building materials based on cement, such as mortar and large concrete.

구체적으로는 포트랜드 시멘트를 주원료로 하여서 되는 몰탈, 큰크리트 기타 시멘트 건축재 및 구축물들에 안료를 혼합하여 착색하는 것에 있어서, 본 발명에 의하여 조성된 혼합물을 시멘트 원료 중량비에 적량을 첨가하므로서 변색을 억제하여 선명한 색상을 장기간 유지케할 수 있음은 물론, 건축재 제품의 강도를 증진시키고, 아울러 내약품성, 내후성이 우수한 색상 시멘트 건축재들을 손쉽게 얻을 수 있게 한 것이다.Specifically, in the coloring of pigments mixed with mortar, large concrete, and other cement building materials and constructions using portland cement as a main raw material, discoloration is suppressed by adding an appropriate amount to the weight ratio of cement raw materials. Not only can it keep the vivid color for a long time, but it also enhances the strength of building products, and also makes it easy to obtain color cement building materials with excellent chemical resistance and weather resistance.

일단적으로, 시멘트 건축재나 구축물들에 있어서, 이들의 외관 심미도를 높히고, 또 상품 가치를 향상시킬 목적으로 몰탈, 큰크리트 및 기타 시멘트 건축재들에 안료를 혼합 하거나 이들 표면에 안료가 혼합된 수성도료를 도포하여 착색을 한다.At one time, in cement building materials or constructions, waterborne paints incorporating or mixing pigments with mortar, large concrete and other cement building materials for the purpose of increasing their appearance aesthetics and improving their commodity value. Apply to color.

그러나 몰탈, 콘크리트 등에 안료를 혼합하여 착색할 경우, 양생과정에 안료가 표면으로 부유되어 색상이 균일하게 침착 되지 못하고, 표면에만 색상이 나타나면서 쉽게 탈색, 변색될 뿐 아니라 강도가 상대적으로 저하되는 결점이 있다.However, when pigments are mixed and mixed with mortar and concrete, the pigments float to the surface during curing, and the color is not uniformly deposited. There is this.

또, 시멘트 그 성질상 공기중에서 수분을 흡수하고, 그로 인한 수화작용으로 생성된 수산화 칼슘이 대기중의 탄산가스와 결합하여 탄산석회를 만들게되는데 이때, 시멘트의 입자는 이 화합물의 피막으로 피복되는 현상이 생기면서 이것은 변색, 퇴색의 가중 요인으로 작용하게 된다. 뿐만 아니라 골재의 알칼리 반응도 복합적으로 작용하여, 색상의 퇴화가 점진적으로 심화되고 제품 강도도 저하 되면서 쉽게파손되는 빈도가 높다. 나아가, 약품에 대한 견뢰도도 낮아 산이나, 알카리, 염, 물, 일광등에 지속적으로 견디지 못하는 결점이 있다.In addition, the cement absorbs moisture in the air, and the calcium hydroxide produced by the hydration effect is combined with carbon dioxide gas in the air to form lime carbonate, in which the particles of cement are coated with the coating of the compound. This occurs as a weighting factor of discoloration and fading. In addition, the alkali reaction of the aggregates also acts in combination, causing the color deterioration to gradually intensify and the product strength to decrease, so that the frequency of breakage is high. In addition, the fastness to the drug is also low, there is a defect that can not continuously endure acid, alkali, salt, water, sunlight and the like.

따라서, 필요한 색상의 밝고 선명한 색체를 장기간 유지 할 수 있는 색상 시멘트 건축재나 구축물을 얻기에는 매우 어려운 실정에 있다. 종전의 공지기술, 예컨데 특허공고번호 제76-199호에서 시멘트 건축재에 착색을 시도한 기술이 알려진바 있으나, 이는 에멀존의 접착력을 이용하여서 된 것이므로 당해 발명에 있어서는 대체로 적절한 기술을 나타대고 있으나 본 발명에서는 응용할 수가 없다.Therefore, it is very difficult to obtain a color cement building material or a structure that can maintain a bright and vivid color of a required color for a long time. Prior art, for example, Patent Publication No. 76-199 has been known for attempting to color the cement building materials, but this is by using the adhesive force of the emulsion zone generally shows the appropriate technology in the present invention, but the present invention Is not applicable.

상기 공지기술은 안료가 혼합된 착색제인 백색 시멘트 수용액에 수용성 아크릴계의 에멀존을 첨가하여, 에멀존의 접착력으로 백색 시멘트 착색기제의 부착력을 증대시키게 한 것이므로 내멀존, 내약품성이 비교적 조하고 특히 내변색성은 극히 낮아 점진 퇴색이나 변색의 방지는 매우 어려운 결점이 있다.Since the known technology is to add a water-soluble acrylic emulsion zone to the aqueous solution of white cement, which is a pigment mixed colorant, to increase the adhesion of the white cement colorant by the adhesive strength of the emulsion zone, it is relatively resistant to the emulsion zone, chemical resistance The discoloration is extremely low, and it is very difficult to prevent gradual fading or discoloration.

본 발명은 상기 공지기술과는 전연 달리 고도의 내후성, 내약품성 및 강도를 가짐과 동시에, 변색이 거의없이 선명한 색상을 장기간 유지할 수 있는 색상 시멘트 건축재용 변색 방지재를 제공하고자 함에 주요 목적이 있다.The present invention has a main object to provide a discoloration preventing material for color cement building material that can maintain a clear color for a long time with almost no discoloration, while having a high weather resistance, chemical resistance and strength unlike the leading edge.

본 발명의 다른 목적은 색상 시멘트 건축재 뿐만 아니라 시멘트 구축물 기타 시멘트 주재의 모든 착색시공물에 광범위하게 널리 이용될 수 있는 신규의 조성물을 제공하고자 한 것이다.It is another object of the present invention to provide a novel composition that can be widely used in a wide variety of colored constructions of cement constructions and other cement bases as well as color cement construction materials.

이와 같은 본 발명의 특징적인 요소로서는 몰탈, 큰크리트등, 포트랜드 시멘트를 주원료로하여 이루어지는 건축재, 구축물들에 안료를 혼합하여 착색을 함에 있어서, 황산 마그네시움(MgSO4), 초산 소오다(NaCH3CO2), 중크롬산 칼리움(K2Cr2O2), 카제인(Casein), 암모니아수(水) 및 물 등으로 조성되는 혼합물 용액을 시멘트 원료 중량비의 미량을 첨가하는 것만으로 변색을 억제하여 선명한 색상을 장기간 유지게할 수 있을 뿐만 아니라 색상 건축재등의 제품 강도 증진을 상승효과로 나타낼 수 있게 한 것이다.Such characteristic elements of the present invention include magnesium sulfate (MgSO 4 ) and soda acetate (NaCH) in the coloring of pigments mixed with building materials and constructs composed mainly of Portland cement, such as mortar and large concrete. 3 CO 2 ), dichromate (K 2 Cr 2 O 2 ), casein (Casein), ammonia water (water) and a mixture solution composed of water, etc. by adding a small amount of the weight ratio of the cement raw material to suppress discoloration Not only can the color be maintained for a long time, but also the synergistic effect of the product strength improvement of the color building materials can be shown.

이와 같은 본 발명을 구체적으로 설명하면 다음과 같다.The present invention will be described in detail as follows.

1. 본 발명 변색 방지제의 조성1. Composition of the Discoloration Preventer of the Present Invention

황산마그네시움 25∼30중량%25-30% by weight of magnesium sulfate

초산소오다 8∼10중량%8-10 wt%

중크롬산칼리움 3∼ 5중량%3 to 5% by weight of dichromium

카제인 3∼ 5중량%Casein 3-5% by weight

암모니아수 0.5중량%0.5% by weight of ammonia

물 40 ∼ 50중량%40-50% by weight of water

2. 본 발명 변색 방지제 조성물의 배합과정2. Mixing process of the present invention discoloration preventing agent composition

본 발명에 의한 변색 방지제는 상기 조성물들에 있어서, 먼저 물을 70℃ 내외의 온도로 가열 후, 여기에 카제연을 넣고, 이어서 암모니아 수를 미량 첨가하여 5∼10분 정도 혼련한 다음 상온에서 방치하여 냉각 시킨다.Discoloration preventing agent according to the present invention, in the above compositions, the water is first heated to a temperature of about 70 ℃, then added the casein, then kneaded for about 5 to 10 minutes by adding a small amount of ammonia and then left at room temperature To cool.

이 냉각 용역에 황산 마그네시움, 초산 소오다, 중크롬산 칼리움 들을 순서대로 투입하고 용액이 기포를 발생할때까지 충분히 교반한다. 기포용액은 약 2시간 정도 상온에서 방치하여 기포가 완전 사멸되었을때 기포가 재 발생하지 않는 범위내에서 서서히 교반하여 숙성 시키므로서 맑은 황색을 띤 용액의 본 발명에 의한 변색 방지제를 얻게 된다.Magnesium sulfate, soda acetate, and potassium dichromate are sequentially added to the cooling service, and the solution is sufficiently stirred until bubbles are generated. The bubble solution is left at room temperature for about 2 hours, and when the bubble is completely killed, the bubble solution is gradually stirred and aged in a range where bubbles are not regenerated, thereby obtaining a discoloration preventing agent according to the present invention in a clear yellowish solution.

이와 같은 본 발명에 의한 변색 방지제의 조성물 중, 카제연(Casein)은 비교적 순수한 형으로 존재하는 단백질의 하나로서 원래 수성도료로서 사용되기도 하지만 본 발명에 있어서는 이후 설명할 초산 나트륨과 결합하여 색상 시멘트 건축재들에 투여되는 안료의 침착 증강제로 이용하기 위한 것이고, 이를 미량의 암포니아수로 혼련함은 카제인, 교질입자가 분산매의 pH에 의하여 매염제들과 친화되게 하므로서 착색을 듭기위한 것이다. 황산 마그네시움은 백색의 결점인 수용성 물질로서 매염제(妹染劑)로서는 공지되어 있기도 하나 염색제인 초산 소오다 및 염료로서의 중크롬 산 칼리움들과 결합하여 안료분산을 용이하게 하고, 산, 알카리, 염, 물, 일광 등에 대한 견뢰도를 증진시키게 한것이다.In such a discoloration preventing agent composition of the present invention, casein (Casein) is one of the proteins present in a relatively pure form, which is originally used as an aqueous coating, but in the present invention, in combination with sodium acetate to be described later in color cement building materials It is intended to be used as a deposition enhancer for pigments administered to them, and kneading them with trace amounts of amphonia water is intended to give coloring by making casein, colloid particles compatible with mordants by the pH of the dispersion medium. Magnesium sulfate is a water-soluble substance which is a white defect and is known as a mordant, but it is combined with soda acetate, a dye, and dichromic acid kalium as a dye, to facilitate pigment dispersion, acid, and alkali. It improves fastness to salt, water, daylight, etc.

본 발명에 있어서, 특히 유의할 점은 상기 조성물들중, 황산 마그네시움은 30중량% 이상의 혼합량에 있어서도 하등 지장이 없으나 초산 소오다 및 중크롬산 칼리움 들에 있어서는 가급적 8∼10중량% 및 3∼5중량%의 배합비가 가장 적절하다In the present invention, it should be noted that in the above compositions, the magnesium sulfate is not inferior even in the mixing amount of 30% by weight or more, but is preferably 8 to 10% by weight and 3 to 5 in soda acetate and dichromium kalium. The blending ratio in weight% is most suitable

이는 초산 소오다 및 중크롬산 칼리움들이 과량으로 혼합된 혼합조성물을 색상 시멘트 건축재들에 첨가하였올때 이들 건축재에는 서서히 탈색현상(약 3개월 경과후)이 나타남을 발견 할 수 있었는데 이의 원인에 대해서는 아직 이론적으로 규명되지는 않았으나 중크롬산 칼리움의 유독성과 초산 소오다에 있어서의 공기중에 풍해(風解)하고 약 알카리성이라는 성질들이 작용하여 점차 퇴색되는 것이 아닌가 생각되고 있다.It was found that when a mixed composition containing an excess of soda acetate and bichromate was added to the color cement building materials, the building material gradually showed discoloration (after about 3 months). Although it is not identified as, it is thought that the toxicity of the dichromium kalium and the soda acetate in air are windy and weakly alkaline.

그러나, 본 발명의 조성물을 상기와 같은 혼합비로 한정하였올 경우, 만족할 만한 효과를 얻을 수 있었음을 수차례의 시험을 거쳐 알 수 있었다.However, when the composition of the present invention was limited to the mixing ratio as described above, it was found through several tests that satisfactory effects were obtained.

[실시예]EXAMPLE

원통 가열부에 물을 49.5중량% 넣고, 이를 70℃ 내외의 온도로 가열 후, 여기에 카제인 5중량%를 넣고 이어서 암모니아수 0.5중량%를 첨가하여 5∼10분 정도 잘 혼련시킨 후 상온에서 방치, 냉각하였다. 이 냉각 용액에 황산 마그네시움 30중량%, 초산 소오다 10중량%, 중크롬산 칼리움 5중량%를 순서대로 투입하며, 용액전부가 거품화 될때까지 격렬하게 교반 하였다. 이 교반 용액을 약 2시간 정도 상온에서 방치하여 거품이 전부 사그러졌을때 서서히 교반, 숙성하여 맑은 황색상의 용액인 본 발명에 의한 변색 방지제를 얻었다.Put 49.5% by weight of water in the cylindrical heating part, heat it to a temperature of about 70 ℃, and then add 5% by weight of casein, and then 0.5% by weight of ammonia water to knead well for about 5 to 10 minutes, then left at room temperature, Cooled. 30 wt% of magnesium sulfate, 10 wt% of sodium acetate, and 5 wt% of dichloromium dichromate were added to the cooling solution in this order, and the mixture was stirred vigorously until foaming was made. This stirred solution was left at room temperature for about 2 hours, and when all the bubbles had collapsed, the mixture was stirred and aged gradually to obtain a discoloration preventing agent according to the present invention which is a clear yellow solution.
