난연 및 방염성이 개선된 목질계 건축 마감재의 제조방법{Method of preparing Wood and Wood Based Finishing materials improved fire and flame-retardant}Method of preparing wood-based building finishing materials with improved flame retardancy and flame retardancy

본 발명은 난연 및 방염성이 개선된 목질계 건축 마감재의 제조방법에 관한 것이다. 보다 구체적으로는, 본 발명은 목질계 건축마감재 소재에 침투성 난연처리제를 침투시킨 후 난연성 도료로 도막을 형성시킴으로써 기존의 난연도료로 도장시 도막마모, 도막박리, 도막 크랙이나 할렬 등으로 방염 또는 난연 성능의 저하문제를 방지하고 방염성능 또는 난연성능을 지속적으로 유지할 수 있는 목질계 건축 마감재의 제조방법에 관한 것이다. The present invention relates to a method for manufacturing a wood-based building finishing material with improved flame retardancy and flame retardancy. More specifically, the present invention permeates a permeable flame-retardant treatment agent into a wood-based building finishing material and forms a coating film with a flame-retardant coating material. It relates to a method for manufacturing a wood-based building finishing material that can prevent performance degradation and continuously maintain flame-retardant performance or flame-retardant performance.

또한, 침투성 방염액 처리의 경우에는 침투성 방염액의 조습성에 의하여 백화발생, 얼룩, 물걸레질 시 방염액 제거, 표면 일어남 등을 효과적으로 방지함으로써 방염성능 또는 난연성능을 지속적으로 유지할 수 있는 목질계 건축 마감재의 제조방법에 관한 것이다. In addition, in the case of permeable flame retardant treatment, it is a wood-based construction that can continuously maintain flame retardant or flame retardant performance by effectively preventing whitening, stains, removal of flame retardant solution when wiping, surface occurrence, etc. It relates to a method of manufacturing a finishing material.

건축 마감재는 크게 내장재, 외장재 및 바닥재로 구분되며, 건축 마감재로 주로 사용되는 재료로는 목재 및 목질재료, 대리석, 현무암, 화강암 등 석재, 금속재 및 타일과 같은 세라믹이 있다. 이중에서 목질계(목질재료, 목재, 합판, 중밀도섬유판 등)는 다른 재료에 비해 사람과 환경에 친화적인 재료로 알려져 있으며, 특히, 충격 및 소음을 효율적으로 흡수하여 조용한 환경을 조성할 수 있으며, 시각적으로도 아름답고 편안한 느낌을 제공하여 전세계적으로 수요와 사용량이 증가하고 있다.Building finishing materials are largely divided into interior materials, exterior materials, and flooring materials. Materials mainly used as building finishing materials include wood and wood materials, marble, basalt, stone materials such as granite, metal materials, and ceramics such as tiles. Among them, wood-based materials (wood materials, wood, plywood, medium-density fiberboard, etc.) are known to be more friendly to people and the environment compared to other materials. , providing a visually beautiful and comfortable feeling, the demand and usage worldwide is increasing.

다만, 목질계 재료는 가열하면 산화되면서 순식간에 건축물을 연소시켜 막대한 인명과 재산 피해를 유발하고 있기 때문에 효과적인 방염 및 난연처리가 필수적으로 요구되고 있다. However, since wood-based materials are oxidized when heated and burn buildings in an instant, causing enormous human life and property damage, effective flame-retardant and flame-retardant treatment are essential.

현재 목질계 건축마감재의 화재안전과 관련하여 처리하는 방법인 후처리 방법은 방염 및 난연성 도료를 건축마감재 시공 후 현장에서 도장하는 방법으로 이루어지고 있는데, 통상 3회 이상 도장으로 도막 두께를 100㎛ 이상 형성시킴으로써 관련 법령 및 기준에서 규정하고 있는 방염성능을 확보하여야 하지만(도 1 참고), 현장 작업 특성(흘러내림, 얼룩발생, 미처리 부분 발생)상 규정 도막두께 확보와 균일한 처리가 곤란하여 방염성능을 확보하기가 현실적으로 어렵고, 따라서 부실방염처리로 인한 화재안전 문제가 발생하고 있다. Currently, the post-treatment method, which is a method of treating wood-based building finishing materials in relation to fire safety, is a method of painting flame-retardant and flame-retardant paints at the site after construction of the building finishing materials. Although it is necessary to secure the flame-retardant performance stipulated in the relevant laws and standards by forming it (refer to Fig. 1), it is difficult to secure the prescribed film thickness and uniform treatment due to the characteristics of the field work (flowing, staining, untreated parts). It is practically difficult to secure, and therefore fire safety problems are occurring due to poor flame retardancy treatment.

또한, 규정대로 100㎛ 이상의 도막 두께를 확보한다고 하여도, 시간 경과에 따른 도막의 갈라짐, 깨짐, 벗겨짐, 마모 등이 발생하게 되므로 화재시 화염이 소재에 닿게 되어 화염의 확대, 잔신, 잔염 등이 발생하는 문제점이 여전히 제기되고 있다(도 2 참고). In addition, even if a coating film thickness of 100 μm or more is secured as prescribed, cracks, cracks, peeling, and abrasion of the coating film over time occur. Problems that occur are still being raised (refer to FIG. 2).

이러한 문제를 해결하고자 수용성의 난연제를 목재 내부에 함침시켜 난연성능을 높이는 방법이 개발되어 사용되고 있다. 하지만, 목재 내부로 함침된 난연제는 흡습 및 조습성 문제로 습기 및 수분을 흡수하게 되어 표면에 결로 및 젖음 현상이 발생하고, 또한, 도 3과 같이 흡습과 건조과정에서 표면이 건조되면 얼룩이나 백화현상이 심하게 발생하게 되며, 표면 오염 물질의 제거(청소 또는 물걸레질)시 표면에 함침된 난연제가 함께 제거되어 방염 및 난연성능이 저하되는 문제가 발생되었다. In order to solve this problem, a method of improving the flame retardant performance by impregnating the inside of the wood with a water-soluble flame retardant has been developed and used. However, the flame retardant impregnated into the wood absorbs moisture and moisture due to moisture absorption and humidity control problems, causing condensation and wetting on the surface. The phenomenon occurs severely, and when the surface contaminants are removed (cleaning or wiping with water), the flame retardant impregnated on the surface is also removed, causing a problem in that the flame retardant and flame retardant performance is lowered.

본 발명은 도막의 갈라짐이나 마모, 벗겨짐 등의 현상이 발생하여도 난연 및 방염 성능을 확보할 수 있고, 마감재 표면에 흡음성 개선 등을 위하여 타공, 홈가공 등을 하여도 방염 및 난연성능을 유지할 수 있는 건축 마감재의 표면 처리 방법을 제공하는 것이다.The present invention can secure flame-retardant and flame-retardant performance even when cracks, abrasion, peeling, etc. occur in the coating film, and can maintain flame-retardant and flame-retardant performance even when drilling or groove processing is performed to improve sound absorption on the surface of the finished material. It is to provide a method for surface treatment of a building finishing material.

본 발명은 표면에 얼룩이나 백화현상, 젖음, 결로 현상 등이 발생하지 않는 건축 마감재의 제조방법을 제공하는 것이다.An object of the present invention is to provide a method for manufacturing a building finishing material that does not cause stains, whitening, wetting, and condensation on the surface.
