Abstract
Description
본 발명은 건축물의 내부에 위치하는 철골 표면이나 콘크리트 표면같은 내부 구조물의 표면에 처리하는 무기질 내화 피복재의 제조방법에 관한 것이다.The present invention relates to a method for producing an inorganic fire-resistant coating material which is treated on the surface of an internal structure such as steel surface or concrete surface located inside the building.
전술한 형태의 내화 피복재는 단열등의 목적으로 건축물의 내부에 노출되는 철골 표면이나 벽면에 처리되고 있는바, 이러한 내화 피복재는 무기질 섬유와 무기질 및 /또는 유기질 결합제를 주제로 포함하고 있으며 내화 피복재의 제품 형태에 따라 건식처리 방법이나 습식 처리 방법에 의하여 피처리면에 부착시키고 있다. 건식처리방법은 피복재의 분사처리시 무기질 섬유, 특히 석면 분말의 비산등으로 환경 오염의 문제가 발생하므로 최근에는 습식처리 방법을 주로 이용하고 있다. 습식 처리방법에 의하면 내화 피복재를 다량의 물을 함유하는 점성 유동체 상태로 만들어서 처리하므로 환경 오염의 문제는 없으나 피복재가 피처리면에 처리된후 교착되고 건조되어 견고하게 부착되는데 시간이 경과함에 따라 건조 수축이 심해서 피복재가 피처리면에서 박리되는 경우가 있다.The above-mentioned fireproof coating material is treated on the steel surface or wall surface exposed to the interior of the building for the purpose of thermal insulation and the like. The fireproof coating material includes inorganic fibers and inorganic and / or organic binders as the subjects. Depending on the type of product, it is adhered to the surface to be treated by a dry treatment method or a wet treatment method. In the dry treatment method, since the problem of environmental pollution occurs due to the scattering of inorganic fibers, especially asbestos powder during spray treatment of the coating material, the wet treatment method is mainly used in recent years. According to the wet treatment method, the refractory coating material is processed into a viscous fluid state containing a large amount of water, so there is no problem of environmental pollution. However, after the coating material is treated on the surface to be treated, it is stuck, dried, and firmly adhered to it. This severe condition may cause the coating material to peel off from the surface to be treated.
특히 건축물의 내부에 처리하는 내화 피복재는 결합제의 대부분이 내화성 물질로 구성되어야 하는바, 종래의 내화 피복재는 피복층의 균열 및 박리현상이 나타나고, 피복층의 균열 및 박리현상을 방지 하기 위하여 다량의 결합제를 사용하는 경우에는 내화 성능과 단열 성능이 규격에 미달하게 되는 문제가 나타났다.In particular, the fireproof coating material to be treated in the interior of the building should be composed mostly of the refractory material, the conventional fireproof coating material is cracking and peeling phenomenon of the coating layer, a large amount of binder to prevent cracking and peeling of the coating layer. In the case of use, the problem that the fire resistance and the insulation performance did not meet the specification.
본 발명자는 전술한 종래 내화 피복재의 문제점을 개선하기 위하여 연구한 결과 무기질 단열재, 특히 질석과 무기섬유 및 소석고를 일정한 비율로 배합하면 종래 피복재에서 나타나는 문제점인 균일 및 박리현상을 억제할 수 있고 작업성을 향상시킬 수 있음을 알게되어 본 발명을 완성하게 된 것이다.The present inventors have studied in order to improve the problems of the above-mentioned conventional fire-resistant coating material, as a result of mixing the inorganic insulating material, especially vermiculite, inorganic fiber and calcined gypsum in a constant ratio, it is possible to suppress the uniformity and peeling phenomenon which is a problem in the conventional coating material and workability It will be appreciated that to improve the present invention will be completed.
본 발명의 목적은 피복층의 균열 및 박리현상이 나타나지 않고 작업성이 양호한 내화 피복재를 제공하기 위한 것이다.An object of the present invention is to provide a fireproof coating material having good workability without cracking and peeling of the coating layer.
본 발명은 소석고 질석 및 무기섬유를 다음의 식에 맞게 배합하는 내화 피복재 제조방법으로 구성된다.The present invention comprises a method for producing a fire-resistant coating material in which calcined gypsum vermiculite and inorganic fibers are blended in accordance with the following formula.
본 발명에 있어서 질석은 가열하여 열팽화시킨 질석을 사용하는바, 경우에따라서는 펠라이트, 규조토, 인조경량 골재등 질석과 유사한 단열 효과와 물성을 갖는 무기질 단열재를 질석대신 사용하거나 질석과 함께 사용할 수도 있다. 이와같은 질석과 단열재는 분말상 또는 입상으로 된 것을 사용할 수 있는 바, 3mm이하의 입도, 특히 0.1-1mm의 입도를 갖는 것이 바람직하다.In the present invention, vermiculite is heated and thermally expanded vermiculite, and in some cases, an inorganic insulator having similar thermal insulation properties and properties similar to vermiculite such as ferrite, diatomaceous earth, artificial light weight aggregate, etc. may be used instead of or in combination with vermiculite. It may be. Such vermiculite and heat insulating material can be used in the form of powder or granules, it is preferred to have a particle size of 3mm or less, in particular 0.1-1mm.
무기질 섬유로는 암면, 유리섬유, 퓌스커, 세라믹섬유, 세피오라이트 등이 사용될 수 있다. 무기섬유는 약 20mm이하의 길이로 절단하여 사용하는바, 특히 0.5-10mm의 길이를 갖는 것이 분무처리가 용이하고 형성된 피복층의 균열을 방지하는데 유리하다.As the inorganic fiber, rock wool, glass fiber, fusing, ceramic fiber, sepiolite and the like can be used. Inorganic fibers are cut to a length of about 20 mm or less, and in particular, having a length of 0.5-10 mm is easy to spray treatment and is advantageous to prevent cracking of the formed coating layer.
본 발명에 의하여 제조되는 내화 피복재는 전술한 소석고, 단열재 및 무기섬유외에도 접착 및 점증제로서 시멘트류, 석회류, 산화티탄, 물 유리 등을 소량 포함할 수 있다. 피복층의 경량화를 위하여 경량제도 소량 포함할 수 있는바, 경량제의 대표적인 것으로는 규조토와 벤토나이트가 있다. 규조토와 벤토나이트는 경량제임과 동시에 단열재이므로 질석의 일부를 규조토나 벤토나이트로 대치하여 사용할 수도 있다. 또한 유연성을 향상시키기 위하여 피복재에 점토류, 펄프, 종이 등을 첨가할 수도 있다.Fire-resistant coating material produced by the present invention may include a small amount of cements, lime, titanium oxide, water glass and the like as an adhesive and a thickener in addition to the above-described calcined gypsum, insulation and inorganic fibers. In order to reduce the weight of the coating layer may also include a small amount of light weight, representative examples of the lightweight agent is diatomaceous earth and bentonite. Diatomaceous earth and bentonite are lightweight and at the same time insulated, so some vermiculite may be replaced by diatomaceous earth or bentonite. Also, clay, pulp, paper, or the like may be added to the coating material in order to improve the flexibility.
그외에도 본 발명의 내화 피복재는 구연산나트륨 단백질, 황산염 염화물등의 응결 경화조제를 소량 포함할 수 있고 카복시메틸셀룰로우스 등과 같은 유기 접착제도 소량 포함할 수도 있다. 그리고 피복층의 경량화를 향상 시키기 위하여 기포제도 포함할 수 있는바, 기포제로는 ＂OSB＂, ＂DE＂등의 상품명으로 판매되는 기포제를 사용할 수 있다.In addition, the refractory coating material of the present invention may contain a small amount of a coagulation curing aid such as sodium citrate protein, sulfate chloride, and may also contain a small amount of an organic adhesive such as carboxymethyl cellulose. In addition, a foaming agent may be included to improve the weight reduction of the coating layer. As the foaming agent, a foaming agent sold under the trade names of “OSB” and “DE” may be used.
본 발명에 의한 내화피복재는 공지의 건식 또는 습식 분무 처리에 의하거나 또는 로울러를 이용한 도장 방법으로 도장 할 수 있다. 본 발명에 의한 내화 피복재를 습식 분무 또는 도장할 때는 본 발명에 의한 피막 조성물에 조성물 중량을 기준으로 120-180%의 물을 가하여 균질이되게 혼합하여야 한다.The fireproof coating according to the present invention can be coated by a known dry or wet spray treatment or by a coating method using a roller. When wet spraying or painting the fire resistant coating material according to the present invention, 120-180% of water based on the composition weight is added to the coating composition according to the present invention and mixed homogeneously.
본 발명에 의한 내화 피복재 제조방법의 일예를 설명하면 다음과 같다.When explaining an example of the manufacturing method of the refractory coating material according to the present invention.
소석고에 소량 첨가물인 기포제, 점증제, 경화조절제등을 배합하여 균질이되게 혼합한 다음 질석과 무기질섬유를 소석고에 대하여 다음의 중량비로 되게 혼합한 다음 방습 포장한다.Mix small amount additives such as foaming agent, thickener, hardening control agent, etc., and mix it homogeneously, mix vermiculite and inorganic fiber with calcined gypsum in the following weight ratio.
본 발명에 의한 내화 피복재를 습식 분무처리할 때는 방습 포장된 내화 피복재를 약 1.2-1.8배의 물에 투입하고 내화 피복재와 물이 균질이 되게 혼합하여 사용한다.When wet-spraying the fireproof coating material according to the present invention, the moisture-proof packaged fireproof coating material is added to about 1.2-1.8 times of water, and the fireproof coating material and water are mixed and used homogeneously.
본 발명에 있어서, 소석고에 대한 단열재와 무기질 섬유의 배합비는 내화 피복재를 처리한 후에 생성된 피복층의 물성에 큰 영향을 미친다. 단열재의 배합량이 소석고 양의 0.63이하로 되면 내화성과 단열성이 저하되고 0.78이상으로 되면 결합력이 약하여 피복층이 박리되는 경우가 나타나며 강도가 저하되게 된다. 또한 무기질 섬유의 배합량이 소석고양의 0.10 이하로 되면 피복층의 인장 강도가 약하여지고 피복층이 균열되는 현상이 나타나며 0.25 이상으로 되면 접착 강도가 저하되고 피복재의 균질성이 저하되며 작업성이 나빠진다. 따라서 소석고 질석- 무기질 섬유의 배합비율은 전술한 배합비의 범위에 들도록 하여야 한다.In the present invention, the blending ratio of the heat insulating material and the inorganic fiber to the calcined gypsum has a great influence on the physical properties of the coating layer formed after treating the fireproof coating material. When the amount of the heat insulating material is less than 0.63 of the amount of calcined gypsum, the fire resistance and heat resistance are lowered, and when the amount of the heat insulating material is 0.78 or more, the bonding strength is weak and the coating layer may be peeled off, resulting in a decrease in strength. In addition, when the amount of the inorganic fiber is less than 0.10 of the calcined cat, the tensile strength of the coating layer becomes weak and the coating layer is cracked. When the amount is 0.25 or more, the adhesive strength is lowered, the homogeneity of the coating material is lowered, and the workability is deteriorated. Therefore, the mixing ratio of calcined tartar vermiculite-inorganic fiber should be in the range of the above-mentioned compounding ratio.
전술한 본 발명의 방법에 의하면 피처리면에 처리된 후에 생성된 피복층이 균열되거나 박리되는 일이 없을 뿐아니라 균열강도와 인장 강도가 우수한 내화 피복재가 얻어진다.According to the method of the present invention described above, a fire resistant coating material excellent in crack strength and tensile strength is obtained as well as the coating layer produced after the treatment to the surface to be treated is not cracked or peeled off.
