Description

폐석회를 이용한 염기성 페인트용 조성물 제조방법{preparation method of composition for alkaline paint using waste lime} Preparation method of composition for alkaline paint using waste lime}

본 발명은 폐석회를 이용한 염기성 페인트용 조성물 제조방법에 관한 것으로, 상세하게는 폐석회를 재활용하여, 환경문제에 대처하고, 경제적으로 바람직하며, 도장의 전착과 도막 형성에 우수하고, 광택 유지성등 도막 특성이 우수하며, 이를 적용한 제품의 표면 부식 억제에 우수한, 폐석회를 이용한 염기성 페인트용 조성물 제조방법에 관한 것이다. The present invention relates to a method for producing a composition for basic paint using waste lime, in particular, to recycle the waste lime, to cope with environmental problems, economically preferred, excellent in electrodeposition of coatings and coating film formation, gloss retention, etc. The present invention relates to a method for producing a composition for basic paint using waste lime, which is excellent in coating properties and excellent in suppressing surface corrosion of a product to which the coating film is applied.

폐석회는, 일반적으로 석회석, 백암등의 가공 처리에 의해 생석회, 소석회, 탄산석회, 소다회등이 생산되는 과정에서 발생하는 부산물로서, pH 12의 강알카리성을 나타낸다. Waste lime is generally a by-product produced in the process of producing quicklime, slaked lime, carbonate lime, soda ash and the like by processing such as limestone and white rock, and exhibits strong alkalinity of pH 12.

이와 같은 폐석회는, 보건 환경 연구원의 분석에 따르면, 총인(TP 물속에 포함된 인의 총량) 농도가 환경부 기준치의 배출 허용 기준(80ppm/L)을 86배 초과한 689.04ppm/L를 갖는데, 이러한 폐석회는 산먼지 및 침출수 등에 의해 환경을 오염시킬 우려가 있으며, 폐석회를 단순히 폐처리할 경우 경제적으로도 바람직하지 않은 바, 폐석회의 재활용이 요구된다.Such waste lime has a 689.04 ppm / L concentration of total phosphorus (total amount of phosphorus in TP water), which is 86 times higher than the Ministry of Environment standard (80 ppm / L). Waste lime may contaminate the environment by acid dust, leachate, etc., and it is economically undesirable to simply waste the waste lime, and recycling of waste lime is required.

그러나 종래 폐석회는 시멘트, 타일 등 건축자재의 원료(국내특허공보 공고번호 제94-4779호, 국내공개특허공보 공개번호 제99-64880호, 국내공개특허공보 공개번호 제99-31805호, 국내공개특허공보 공개번호 제2000-24562호 등)나 석회비료로 일부사용되는 것을 제외하고는 거의 재활용되지 않고, 대부분 폐처리되어 매립되는 실정에 있어, 종래와 다른 새로운 재활용 방법이 예의 요구된다.However, the conventional waste lime is a raw material of building materials such as cement, tiles (Korean Patent Publication No. 94-4779, Domestic Publication No. 99-64880, Korean Publication No. 99-31805, Domestic Except for the use of JP-A-2000-24562 and the like as part of lime fertilizers, it is hardly recycled, and most of the wastes are disposed of in landfills.

한편, 종래 페인트에 이용되는 착색 안료의 경우는, 도장의 전착과 도막 형성에 있어서 바람직하지 않은데, 특히 산업용 소부도료인 산화연의 제조 과정에서, 보다 더 강한 착상을 갖도록 하는 염기성 규조 안료가 필요하다.On the other hand, in the case of colored pigments used in conventional paints, they are not preferable in electrodeposition of coatings and coating film formation. Especially, in the process of producing lead oxide, which is an industrial baking agent, basic diatom pigments are required to have a stronger idea.

또한, 도료가 전착되는 철판의 표면은 철판의 부식에 의해 마이크론 단위에서 표면이 상당히 거칠고 엠보싱을 갖는데, 이러한 부식의 원인은 철박테리아가 공기중에 번식하여 금속의 표면에 침투하여 철을 산화시키기 때문으로, 이러한 철박테리아의 성장을 억제시킬 필요가 있으나, 종래의 도료로는 철박테리아의 성장을 억제하는데 한계가 있었다.In addition, the surface of the iron plate to which the paint is electrodeposited has a very rough surface at the micron unit due to the corrosion of the iron plate and has embossing. The reason for this corrosion is because the iron bacteria multiply in the air and penetrate the surface of the metal to oxidize iron. It is necessary to suppress the growth of such iron bacteria, but conventional paints have had limitations in suppressing the growth of iron bacteria.

그리고, 종래 페인트에 이용되는 페놀변성 알키드 수지를 사용하는 알키드 에나멜의 경우는, 알키드 수지의 성질에 페놀 수지의 성질이 가해져 부착성, 내수성, 내약품성이 우수하나, 도막의 보색성, 광택 유지성이 낮다는 한계가 있었다.In the case of alkyd enamels using phenol-modified alkyd resins used in conventional paints, the properties of phenol resins are added to the properties of alkyd resins to provide excellent adhesion, water resistance, and chemical resistance, but the complementary color and gloss retention of coating films are excellent. There was a limit of low.

그리고, 종래 페인트에 이용되는 에멀젼 도료의 경우에도, 도장의 전착 특성과 도막 형성이 미비하여, 제품의 수명이 낮다는 한계가 있었다.In addition, even in the case of emulsion paints used in conventional paints, electrodeposition characteristics and coating film formation of coatings are inadequate, and there is a limit of low product life.

따라서, 본 발명자들은 상기한 폐석회를 재활용하여, 환경 문제에 대처하고, 경제적으로 유익하면서도, 폐석회의 특질이 가장 적합하게 이용되도록 이를 염기성 페인트용 조성물에 적용하되, 바람직한 도장 전착 및 도막 형성을 가능하게 하고, 도막 특성을 향상하며, 표면 부식을 억제하기 위한, 신규한 폐석회를 이용한 염기성 페인트용 조성물의 제조 방법에 대하여 예의 연구하여 왔다.Accordingly, the present inventors recycle the waste lime as described above to cope with environmental problems and economically, while applying it to the composition for basic paint so that the characteristics of the waste lime are most suitably utilized, the desired coating electrodeposition and coating film can be formed. The manufacturing method of the composition for basic paints using the new waste lime for making it, to improve a coating film characteristic, and to suppress surface corrosion has been intensively studied.

It provides a composition obtained by remixing and heating each waste lime, rice straw, and red soil, which is suitable for use in basic paints, which is preferable from an environmental and economical point of view, and has a significant effect on the electrodeposition of coatings and the formation of a coating film. It is based on the technical idea that the coating properties can be improved, and the surface properties can be improved by preventing corrosion of the surface of the substrate to be coated.

본 발명에 따른 폐석회를 이용한 염기성 페인트용 조성물의 제조 방법은, 먼저, 폐석회의 산도를 떨어뜨리기 위해, 폐석회, 적토, 볏짚을 예를 들어 가마와 같은 가열기에 넣어 혼합하고 가열하여 열처리하는 단계(S1)를 거치도록 한다.In the method for producing a composition for basic paint using waste lime according to the present invention, first, in order to reduce the acidity of waste lime, waste lime, red soil, rice straw is put into a heater such as a kiln, for example, mixed and heated to heat treatment.

이때, 상기 폐석회는 10kg을 이용하고, 상기 적토는 1.2kg을 이용하고, 상기 볏짚은 1kg을 이용하는 것이 적절한 중화를 위해 바람직하다. At this time, the waste lime is used for 10kg, the red soil is used for 1.2kg, the rice straw is preferably used for proper neutralization.

상기 적토는 그 구입이 쉬우므로, 제조 단가의 절감 및 원료 구입의 용이라는 측면에서 우수하다. Since the red soil is easy to purchase, it is excellent in terms of reducing the manufacturing cost and purchasing of raw materials.

한편, 상기 열처리를 함에 있어서, 약 580℃의 온도 분위기에서 약 8분간 열처리를 하는 것이 바람직한데, 이와 같은 열처리 과정에서, 볏짚으로부터의 재와 연기로 폐석회의 산도의 수치를 떨어뜨릴 수 있게 된다.On the other hand, in the heat treatment, it is preferable to perform a heat treatment for about 8 minutes in a temperature atmosphere of about 580 ℃, in this heat treatment process, it is possible to reduce the acidity of the waste lime by ash and smoke from rice straw.

다음으로, 본 발명에서는, 열처리된 폐석회를 분쇄한 후 집진하고, 이에 열처리에 의해 태워진 볏짚의 재 및 열처리에 의해 집진된 적토분을 다시 혼합하고, 이들에 열을 가하며 교반하는 단계(S2)를 거치게 된다.Next, in the present invention, the heat-treated waste lime is pulverized and collected, and the ash of the rice straw burned by the heat treatment and the red earth powder collected by the heat treatment again mixed, applying heat to them and stirring (S2 ).

이와 같은 S2 단계에서는 앞서 S1 단계에서 폐석회, 볏짚 및 적토분을 혼합하여 열처리한 것을 그대로 사용할 수도 있으나, 상기 S1단계로부터 열처리된 폐석회, 볏짚, 적토분 각각을 별도로 더 열처리하여 사용할 수도 있다.In this step S2 may be used as the heat treatment by mixing the waste lime, rice straw and red clay powder in step S1 as above, but may be further heat-treated each of the waste lime, rice straw, red soil powder heat treated from the step S1.

이때, 열처리된 폐석회를 입경이 약 650㎛의 입자 크기를 갖도록 분쇄하는 것이 바람직하다. 이와 같은 입자크기에서 페인트에의 이용이 적절하다. 그리고, 열처리된 폐석회는 약 10kg을 집진하여 이용하는 것이 바람직하다.At this time, the heat-treated waste lime is preferably pulverized so as to have a particle size of about 650㎛.

After mixing in this manner, a temperature atmosphere of about 70 ° C. is formed and stirred in such a temperature atmosphere. At this time, it is appropriate to utilize the radiant heat from the heater used previously.

[실시예]EXAMPLE

본 실시예에서는 폐석회 10kg과 적토 1.2kg 볏짚 1kg의 비율로 가마에 넣어 580℃의 고온으로 약 8분정도 열처리를 하였다. 이때 볏짚에서 나오는 재와 연기에 의하여 폐석회의 산도의 수치가 현격히 낮아지게 된다. In the present embodiment, the kiln was put in a kiln at a ratio of 10 kg of waste lime and 1 kg of red straw 1.2 kg rice straw, and heat-treated at about 580 ° C. for about 8 minutes. At this time, the acidity of waste lime is significantly lowered by ash and smoke from rice straw.

상기 과정을 거쳐 조성된 폐석회를 완전히 식힌 다음 약 650미크론의 가는 입자로 분쇄하여 집진한 후 10kg과 볏집을 태운 재(650미크론) 35g과 900℃로 열처리되어 집진한 적토분(650미크론)을 골고루 혼합하며, 이 과정에 기포 방지제인 이소옥틸알콜을 약 1.25mg을 넣어 가마로부터 약 70℃의 복사열을 가하여 다시 교반하여 분말로 가공한다. 완성된 제품을 지정된 용기에 저장하고, 가능하면 25kg의 무게로 계근한 뒤 포대에 담아 포장하여, 페인트의 재료인 안료로 사용한다.
